All -development is happening in the PCRE2 10.xx series. - -Version 8.38 23-November-2015 ------------------------------ - -1. If a group that contained a recursive back reference also contained a - forward reference subroutine call followed by a non-forward-reference - subroutine call, for example /.((?2)(?R)\1)()/, pcre2_compile() failed to - compile correct code, leading to undefined behaviour or an internally - detected error. This bug was discovered by the LLVM fuzzer. - -2. Quantification of certain items (e.g. atomic back references) could cause - incorrect code to be compiled when recursive forward references were - involved. For example, in this pattern: /(?1)()((((((\1++))\x85)+)|))/. - This bug was discovered by the LLVM fuzzer. - -3. A repeated conditional group whose condition was a reference by name caused - a buffer overflow if there was more than one group with the given name. - This bug was discovered by the LLVM fuzzer. - -4. A recursive back reference by name within a group that had the same name as - another group caused a buffer overflow. For example: - /(?J)(?'d'(?'d'\g{d}))/. This bug was discovered by the LLVM fuzzer. - -5. A forward reference by name to a group whose number is the same as the - current group, for example in this pattern: /(?|(\k'Pm')|(?'Pm'))/, caused - a buffer overflow at compile time. This bug was discovered by the LLVM - fuzzer. - -6. A lookbehind assertion within a set of mutually recursive subpatterns could - provoke a buffer overflow. This bug was discovered by the LLVM fuzzer. - -7. Another buffer overflow bug involved duplicate named groups with a - reference between their definition, with a group that reset capture - numbers, for example: /(?J:(?|(?'R')(\k'R')|((?'R'))))/. This has been - fixed by always allowing for more memory, even if not needed. (A proper fix - is implemented in PCRE2, but it involves more refactoring.) - -8. There was no check for integer overflow in subroutine calls such as (?123). - -9. The table entry for \l in EBCDIC environments was incorrect, leading to its - being treated as a literal 'l' instead of causing an error. - -10. There was a buffer overflow if pcre_exec() was called with an ovector of - size 1. This bug was found by american fuzzy lop. - -11. If a non-capturing group containing a conditional group that could match - an empty string was repeated, it was not identified as matching an empty - string itself. For example: /^(?:(?(1)x|)+)+$()/. - -12. In an EBCDIC environment, pcretest was mishandling the escape sequences - \a and \e in test subject lines. - -13. In an EBCDIC environment, \a in a pattern was converted to the ASCII - instead of the EBCDIC value. - -14. The handling of \c in an EBCDIC environment has been revised so that it is - now compatible with the specification in Perl's perlebcdic page. - -15. The EBCDIC character 0x41 is a non-breaking space, equivalent to 0xa0 in - ASCII/Unicode. This has now been added to the list of characters that are - recognized as white space in EBCDIC. - -16. When PCRE was compiled without UCP support, the use of \p and \P gave an - error (correctly) when used outside a class, but did not give an error - within a class. - -17. \h within a class was incorrectly compiled in EBCDIC environments. - -18. A pattern with an unmatched closing parenthesis that contained a backward - assertion which itself contained a forward reference caused buffer - overflow. And example pattern is: /(?=di(?<=(?1))|(?=(.))))/. - -19. JIT should return with error when the compiled pattern requires more stack - space than the maximum. - -20. A possessively repeated conditional group that could match an empty string, - for example, /(?(R))*+/, was incorrectly compiled. - -21. Fix infinite recursion in the JIT compiler when certain patterns such as - /(?:|a|){100}x/ are analysed. - -22. Some patterns with character classes involving [: and \\ were incorrectly - compiled and could cause reading from uninitialized memory or an incorrect - error diagnosis. - -23. Pathological patterns containing many nested occurrences of [: caused - pcre_compile() to run for a very long time. - -24. A conditional group with only one branch has an implicit empty alternative - branch and must therefore be treated as potentially matching an empty - string. - -25. If (?R was followed by - or + incorrect behaviour happened instead of a - diagnostic. - -26. Arrange to give up on finding the minimum matching length for overly - complex patterns. - -27. Similar to (4) above: in a pattern with duplicated named groups and an - occurrence of (?| it is possible for an apparently non-recursive back - reference to become recursive if a later named group with the relevant - number is encountered. This could lead to a buffer overflow. Wen Guanxing - from Venustech ADLAB discovered this bug. - -28. If pcregrep was given the -q option with -c or -l, or when handling a - binary file, it incorrectly wrote output to stdout. - -29. The JIT compiler did not restore the control verb head in case of *THEN - control verbs. This issue was found by Karl Skomski with a custom LLVM - fuzzer. - -30. Error messages for syntax errors following \g and \k were giving inaccurate - offsets in the pattern. - -31. Added a check for integer overflow in conditions (?(<digits>) and - (?(R<digits>). This omission was discovered by Karl Skomski with the LLVM - fuzzer. - -32. Handling recursive references such as (?2) when the reference is to a group - later in the pattern uses code that is very hacked about and error-prone. - It has been re-written for PCRE2. Here in PCRE1, a check has been added to - give an internal error if it is obvious that compiling has gone wrong. - -33. The JIT compiler should not check repeats after a {0,1} repeat byte code. - This issue was found by Karl Skomski with a custom LLVM fuzzer. - -34. The JIT compiler should restore the control chain for empty possessive - repeats. This issue was found by Karl Skomski with a custom LLVM fuzzer. - -35. Match limit check added to JIT recursion. This issue was found by Karl - Skomski with a custom LLVM fuzzer. - -36. Yet another case similar to 27 above has been circumvented by an - unconditional allocation of extra memory. This issue is fixed "properly" in - PCRE2 by refactoring the way references are handled. Wen Guanxing - from Venustech ADLAB discovered this bug. - -37. Fix two assertion fails in JIT. These issues were found by Karl Skomski - with a custom LLVM fuzzer. - -38. Fixed a corner case of range optimization in JIT. - -39. An incorrect error "overran compiling workspace" was given if there were - exactly enough group forward references such that the last one extended - into the workspace safety margin. The next one would have expanded the - workspace. The test for overflow was not including the safety margin. - -40. A match limit issue is fixed in JIT which was found by Karl Skomski - with a custom LLVM fuzzer. - -41. Remove the use of /dev/null in testdata/testinput2, because it doesn't - work under Windows. (Why has it taken so long for anyone to notice?) - -42. In a character class such as [\W\p{Any}] where both a negative-type escape - ("not a word character") and a property escape were present, the property - escape was being ignored. - -43. Fix crash caused by very long (*MARK) or (*THEN) names. - -44. A sequence such as [[:punct:]b] that is, a POSIX character class followed - by a single ASCII character in a class item, was incorrectly compiled in - UCP mode. The POSIX class got lost, but only if the single character - followed it. - -45. [:punct:] in UCP mode was matching some characters in the range 128-255 - that should not have been matched. - -46. If [:^ascii:] or [:^xdigit:] or [:^cntrl:] are present in a non-negated - class, all characters with code points greater than 255 are in the class. - When a Unicode property was also in the class (if PCRE_UCP is set, escapes - such as \w are turned into Unicode properties), wide characters were not - correctly handled, and could fail to match. - - -Version 8.37 28-April-2015 --------------------------- - -1. When an (*ACCEPT) is triggered inside capturing parentheses, it arranges - for those parentheses to be closed with whatever has been captured so far. - However, it was failing to mark any other groups between the hightest - capture so far and the currrent group as "unset". Thus, the ovector for - those groups contained whatever was previously there. An example is the - pattern /(x)|((*ACCEPT))/ when matched against "abcd". - -2. If an assertion condition was quantified with a minimum of zero (an odd - thing to do, but it happened), SIGSEGV or other misbehaviour could occur. - -3. If a pattern in pcretest input had the P (POSIX) modifier followed by an - unrecognized modifier, a crash could occur. - -4. An attempt to do global matching in pcretest with a zero-length ovector - caused a crash. - -5. Fixed a memory leak during matching that could occur for a subpattern - subroutine call (recursive or otherwise) if the number of captured groups - that had to be saved was greater than ten. - -6. Catch a bad opcode during auto-possessification after compiling a bad UTF - string with NO_UTF_CHECK. This is a tidyup, not a bug fix, as passing bad - UTF with NO_UTF_CHECK is documented as having an undefined outcome. - -7. A UTF pattern containing a "not" match of a non-ASCII character and a - subroutine reference could loop at compile time. Example: /[^\xff]((?1))/. - -8. When a pattern is compiled, it remembers the highest back reference so that - when matching, if the ovector is too small, extra memory can be obtained to - use instead. A conditional subpattern whose condition is a check on a - capture having happened, such as, for example in the pattern - /^(?:(a)|b)(?(1)A|B)/, is another kind of back reference, but it was not - setting the highest backreference number. This mattered only if pcre_exec() - was called with an ovector that was too small to hold the capture, and there - was no other kind of back reference (a situation which is probably quite - rare). The effect of the bug was that the condition was always treated as - FALSE when the capture could not be consulted, leading to a incorrect - behaviour by pcre_exec(). This bug has been fixed. - -9. A reference to a duplicated named group (either a back reference or a test - for being set in a conditional) that occurred in a part of the pattern where - PCRE_DUPNAMES was not set caused the amount of memory needed for the pattern - to be incorrectly calculated, leading to overwriting. - -10. A mutually recursive set of back references such as (\2)(\1) caused a - segfault at study time (while trying to find the minimum matching length). - The infinite loop is now broken (with the minimum length unset, that is, - zero). - -11. If an assertion that was used as a condition was quantified with a minimum - of zero, matching went wrong. In particular, if the whole group had - unlimited repetition and could match an empty string, a segfault was - likely. The pattern (?(?=0)?)+ is an example that caused this. Perl allows - assertions to be quantified, but not if they are being used as conditions, - so the above pattern is faulted by Perl. PCRE has now been changed so that - it also rejects such patterns. - -12. A possessive capturing group such as (a)*+ with a minimum repeat of zero - failed to allow the zero-repeat case if pcre2_exec() was called with an - ovector too small to capture the group. - -13. Fixed two bugs in pcretest that were discovered by fuzzing and reported by - Red Hat Product Security: - - (a) A crash if /K and /F were both set with the option to save the compiled - pattern. - - (b) Another crash if the option to print captured substrings in a callout - was combined with setting a null ovector, for example \O\C+ as a subject - string. - -14. A pattern such as "((?2){0,1999}())?", which has a group containing a - forward reference repeated a large (but limited) number of times within a - repeated outer group that has a zero minimum quantifier, caused incorrect - code to be compiled, leading to the error "internal error: - previously-checked referenced subpattern not found" when an incorrect - memory address was read. This bug was reported as "heap overflow", - discovered by Kai Lu of Fortinet's FortiGuard Labs and given the CVE number - CVE-2015-2325. - -23. A pattern such as "((?+1)(\1))/" containing a forward reference subroutine - call within a group that also contained a recursive back reference caused - incorrect code to be compiled. This bug was reported as "heap overflow", - discovered by Kai Lu of Fortinet's FortiGuard Labs, and given the CVE - number CVE-2015-2326. - -24. Computing the size of the JIT read-only data in advance has been a source - of various issues, and new ones are still appear unfortunately. To fix - existing and future issues, size computation is eliminated from the code, - and replaced by on-demand memory allocation. - -25. A pattern such as /(?i)[A-`]/, where characters in the other case are - adjacent to the end of the range, and the range contained characters with - more than one other case, caused incorrect behaviour when compiled in UTF - mode. In that example, the range a-j was left out of the class. - -26. Fix JIT compilation of conditional blocks, which assertion - is converted to (*FAIL). E.g: /(?(?!))/. - -27. The pattern /(?(?!)^)/ caused references to random memory. This bug was - discovered by the LLVM fuzzer. - -28. The assertion (?!) is optimized to (*FAIL). This was not handled correctly - when this assertion was used as a condition, for example (?(?!)a|b). In - pcre2_match() it worked by luck; in pcre2_dfa_match() it gave an incorrect - error about an unsupported item. - -29. For some types of pattern, for example /Z*(|d*){216}/, the auto- - possessification code could take exponential time to complete. A recursion - depth limit of 1000 has been imposed to limit the resources used by this - optimization. - -30. A pattern such as /(*UTF)[\S\V\H]/, which contains a negated special class - such as \S in non-UCP mode, explicit wide characters (> 255) can be ignored - because \S ensures they are all in the class. The code for doing this was - interacting badly with the code for computing the amount of space needed to - compile the pattern, leading to a buffer overflow. This bug was discovered - by the LLVM fuzzer. - -31. A pattern such as /((?2)+)((?1))/ which has mutual recursion nested inside - other kinds of group caused stack overflow at compile time. This bug was - discovered by the LLVM fuzzer. - -32. A pattern such as /(?1)(?#?'){8}(a)/ which had a parenthesized comment - between a subroutine call and its quantifier was incorrectly compiled, - leading to buffer overflow or other errors. This bug was discovered by the - LLVM fuzzer. - -33. The illegal pattern /(?(?<E>.*!.*)?)/ was not being diagnosed as missing an - assertion after (?(. The code was failing to check the character after - (?(?< for the ! or = that would indicate a lookbehind assertion. This bug - was discovered by the LLVM fuzzer. - -34. A pattern such as /X((?2)()*+){2}+/ which has a possessive quantifier with - a fixed maximum following a group that contains a subroutine reference was - incorrectly compiled and could trigger buffer overflow. This bug was - discovered by the LLVM fuzzer. - -35. A mutual recursion within a lookbehind assertion such as (?<=((?2))((?1))) - caused a stack overflow instead of the diagnosis of a non-fixed length - lookbehind assertion. This bug was discovered by the LLVM fuzzer. - -36. The use of \K in a positive lookbehind assertion in a non-anchored pattern - (e.g. /(?<=\Ka)/) could make pcregrep loop. - -37. There was a similar problem to 36 in pcretest for global matches. - -38. If a greedy quantified \X was preceded by \C in UTF mode (e.g. \C\X*), - and a subsequent item in the pattern caused a non-match, backtracking over - the repeated \X did not stop, but carried on past the start of the subject, - causing reference to random memory and/or a segfault. There were also some - other cases where backtracking after \C could crash. This set of bugs was - discovered by the LLVM fuzzer. - -39. The function for finding the minimum length of a matching string could take - a very long time if mutual recursion was present many times in a pattern, - for example, /((?2){73}(?2))((?1))/. A better mutual recursion detection - method has been implemented. This infelicity was discovered by the LLVM - fuzzer. - -40. Static linking against the PCRE library using the pkg-config module was - failing on missing pthread symbols. - - -Version 8.36 26-September-2014 ------------------------------- - -1. Got rid of some compiler warnings in the C++ modules that were shown up by - -Wmissing-field-initializers and -Wunused-parameter. - -2. The tests for quantifiers being too big (greater than 65535) were being - applied after reading the number, and stupidly assuming that integer - overflow would give a negative number. The tests are now applied as the - numbers are read. - -3. Tidy code in pcre_exec.c where two branches that used to be different are - now the same. - -4. The JIT compiler did not generate match limit checks for certain - bracketed expressions with quantifiers. This may lead to exponential - backtracking, instead of returning with PCRE_ERROR_MATCHLIMIT. This - issue should be resolved now. - -5. Fixed an issue, which occures when nested alternatives are optimized - with table jumps. - -6. Inserted two casts and changed some ints to size_t in the light of some - reported 64-bit compiler warnings (Bugzilla 1477). - -7. Fixed a bug concerned with zero-minimum possessive groups that could match - an empty string, which sometimes were behaving incorrectly in the - interpreter (though correctly in the JIT matcher). This pcretest input is - an example: - - '\A(?:[^"]++|"(?:[^"]*+|"")*+")++' - NON QUOTED "QUOT""ED" AFTER "NOT MATCHED - - the interpreter was reporting a match of 'NON QUOTED ' only, whereas the - JIT matcher and Perl both matched 'NON QUOTED "QUOT""ED" AFTER '. The test - for an empty string was breaking the inner loop and carrying on at a lower - level, when possessive repeated groups should always return to a higher - level as they have no backtrack points in them. The empty string test now - occurs at the outer level. - -8. Fixed a bug that was incorrectly auto-possessifying \w+ in the pattern - ^\w+(?>\s*)(?<=\w) which caused it not to match "test test". - -9. Give a compile-time error for \o{} (as Perl does) and for \x{} (which Perl - doesn't). - -10. Change 8.34/15 introduced a bug that caused the amount of memory needed - to hold a pattern to be incorrectly computed (too small) when there were - named back references to duplicated names. This could cause "internal - error: code overflow" or "double free or corruption" or other memory - handling errors. - -11. When named subpatterns had the same prefixes, back references could be - confused. For example, in this pattern: - - /(?P<Name>a)?(?P<Name2>b)?(?(<Name>)c|d)*l/ - - the reference to 'Name' was incorrectly treated as a reference to a - duplicate name. - -12. A pattern such as /^s?c/mi8 where the optional character has more than - one "other case" was incorrectly compiled such that it would only try to - match starting at "c". - -13. When a pattern starting with \s was studied, VT was not included in the - list of possible starting characters; this should have been part of the - 8.34/18 patch. - -14. If a character class started [\Qx]... where x is any character, the class - was incorrectly terminated at the ]. - -15. If a pattern that started with a caseless match for a character with more - than one "other case" was studied, PCRE did not set up the starting code - unit bit map for the list of possible characters. Now it does. This is an - optimization improvement, not a bug fix. - -16. The Unicode data tables have been updated to Unicode 7.0.0. - -17. Fixed a number of memory leaks in pcregrep. - -18. Avoid a compiler warning (from some compilers) for a function call with - a cast that removes "const" from an lvalue by using an intermediate - variable (to which the compiler does not object). - -19. Incorrect code was compiled if a group that contained an internal recursive - back reference was optional (had quantifier with a minimum of zero). This - example compiled incorrect code: /(((a\2)|(a*)\g<-1>))*/ and other examples - caused segmentation faults because of stack overflows at compile time. - -20. A pattern such as /((?(R)a|(?1)))+/, which contains a recursion within a - group that is quantified with an indefinite repeat, caused a compile-time - loop which used up all the system stack and provoked a segmentation fault. - This was not the same bug as 19 above. - -21. Add PCRECPP_EXP_DECL declaration to operator<< in pcre_stringpiece.h. - Patch by Mike Frysinger. - - -Version 8.35 04-April-2014 --------------------------- - -1. A new flag is set, when property checks are present in an XCLASS. - When this flag is not set, PCRE can perform certain optimizations - such as studying these XCLASS-es. - -2. The auto-possessification of character sets were improved: a normal - and an extended character set can be compared now. Furthermore - the JIT compiler optimizes more character set checks. - -3. Got rid of some compiler warnings for potentially uninitialized variables - that show up only when compiled with -O2. - -4. A pattern such as (?=ab\K) that uses \K in an assertion can set the start - of a match later then the end of the match. The pcretest program was not - handling the case sensibly - it was outputting from the start to the next - binary zero. It now reports this situation in a message, and outputs the - text from the end to the start. - -5. Fast forward search is improved in JIT. Instead of the first three - characters, any three characters with fixed position can be searched. - Search order: first, last, middle. - -6. Improve character range checks in JIT. Characters are read by an inprecise - function now, which returns with an unknown value if the character code is - above a certain threshold (e.g: 256). The only limitation is that the value - must be bigger than the threshold as well. This function is useful when - the characters above the threshold are handled in the same way. - -7. The macros whose names start with RAWUCHAR are placeholders for a future - mode in which only the bottom 21 bits of 32-bit data items are used. To - make this more memorable for those maintaining the code, the names have - been changed to start with UCHAR21, and an extensive comment has been added - to their definition. - -8. Add missing (new) files sljitNativeTILEGX.c and sljitNativeTILEGX-encoder.c - to the export list in Makefile.am (they were accidentally omitted from the - 8.34 tarball). - -9. The informational output from pcretest used the phrase "starting byte set" - which is inappropriate for the 16-bit and 32-bit libraries. As the output - for "first char" and "need char" really means "non-UTF-char", I've changed - "byte" to "char", and slightly reworded the output. The documentation about - these values has also been (I hope) clarified. - -10. Another JIT related optimization: use table jumps for selecting the correct - backtracking path, when more than four alternatives are present inside a - bracket. - -11. Empty match is not possible, when the minimum length is greater than zero, - and there is no \K in the pattern. JIT should avoid empty match checks in - such cases. - -12. In a caseless character class with UCP support, when a character with more - than one alternative case was not the first character of a range, not all - the alternative cases were added to the class. For example, s and \x{17f} - are both alternative cases for S: the class [RST] was handled correctly, - but [R-T] was not. - -13. The configure.ac file always checked for pthread support when JIT was - enabled. This is not used in Windows, so I have put this test inside a - check for the presence of windows.h (which was already tested for). - -14. Improve pattern prefix search by a simplified Boyer-Moore algorithm in JIT. - The algorithm provides a way to skip certain starting offsets, and usually - faster than linear prefix searches. - -15. Change 13 for 8.20 updated RunTest to check for the 'fr' locale as well - as for 'fr_FR' and 'french'. For some reason, however, it then used the - Windows-specific input and output files, which have 'french' screwed in. - So this could never have worked. One of the problems with locales is that - they aren't always the same. I have now updated RunTest so that it checks - the output of the locale test (test 3) against three different output - files, and it allows the test to pass if any one of them matches. With luck - this should make the test pass on some versions of Solaris where it was - failing. Because of the uncertainty, the script did not used to stop if - test 3 failed; it now does. If further versions of a French locale ever - come to light, they can now easily be added. - -16. If --with-pcregrep-bufsize was given a non-integer value such as "50K", - there was a message during ./configure, but it did not stop. This now - provokes an error. The invalid example in README has been corrected. - If a value less than the minimum is given, the minimum value has always - been used, but now a warning is given. - -17. If --enable-bsr-anycrlf was set, the special 16/32-bit test failed. This - was a bug in the test system, which is now fixed. Also, the list of various - configurations that are tested for each release did not have one with both - 16/32 bits and --enable-bar-anycrlf. It now does. - -18. pcretest was missing "-C bsr" for displaying the \R default setting. - -19. Little endian PowerPC systems are supported now by the JIT compiler. - -20. The fast forward newline mechanism could enter to an infinite loop on - certain invalid UTF-8 input. Although we don't support these cases - this issue can be fixed by a performance optimization. - -21. Change 33 of 8.34 is not sufficient to ensure stack safety because it does - not take account if existing stack usage. There is now a new global - variable called pcre_stack_guard that can be set to point to an external - function to check stack availability. It is called at the start of - processing every parenthesized group. - -22. A typo in the code meant that in ungreedy mode the max/min qualifier - behaved like a min-possessive qualifier, and, for example, /a{1,3}b/U did - not match "ab". - -23. When UTF was disabled, the JIT program reported some incorrect compile - errors. These messages are silenced now. - -24. Experimental support for ARM-64 and MIPS-64 has been added to the JIT - compiler. - -25. Change all the temporary files used in RunGrepTest to be different to those - used by RunTest so that the tests can be run simultaneously, for example by - "make -j check". - - -Version 8.34 15-December-2013 ------------------------------ - -1. Add pcre[16|32]_jit_free_unused_memory to forcibly free unused JIT - executable memory. Patch inspired by Carsten Klein. - -2. ./configure --enable-coverage defined SUPPORT_GCOV in config.h, although - this macro is never tested and has no effect, because the work to support - coverage involves only compiling and linking options and special targets in - the Makefile. The comment in config.h implied that defining the macro would - enable coverage support, which is totally false. There was also support for - setting this macro in the CMake files (my fault, I just copied it from - configure). SUPPORT_GCOV has now been removed. - -3. Make a small performance improvement in strlen16() and strlen32() in - pcretest. - -4. Change 36 for 8.33 left some unreachable statements in pcre_exec.c, - detected by the Solaris compiler (gcc doesn't seem to be able to diagnose - these cases). There was also one in pcretest.c. - -5. Cleaned up a "may be uninitialized" compiler warning in pcre_exec.c. - -6. In UTF mode, the code for checking whether a group could match an empty - string (which is used for indefinitely repeated groups to allow for - breaking an infinite loop) was broken when the group contained a repeated - negated single-character class with a character that occupied more than one - data item and had a minimum repetition of zero (for example, [^\x{100}]* in - UTF-8 mode). The effect was undefined: the group might or might not be - deemed as matching an empty string, or the program might have crashed. - -7. The code for checking whether a group could match an empty string was not - recognizing that \h, \H, \v, \V, and \R must match a character. - -8. Implemented PCRE_INFO_MATCH_EMPTY, which yields 1 if the pattern can match - an empty string. If it can, pcretest shows this in its information output. - -9. Fixed two related bugs that applied to Unicode extended grapheme clusters - that were repeated with a maximizing qualifier (e.g. \X* or \X{2,5}) when - matched by pcre_exec() without using JIT: - - (a) If the rest of the pattern did not match after a maximal run of - grapheme clusters, the code for backing up to try with fewer of them - did not always back up over a full grapheme when characters that do not - have the modifier quality were involved, e.g. Hangul syllables. - - (b) If the match point in a subject started with modifier character, and - there was no match, the code could incorrectly back up beyond the match - point, and potentially beyond the first character in the subject, - leading to a segfault or an incorrect match result. - -10. A conditional group with an assertion condition could lead to PCRE - recording an incorrect first data item for a match if no other first data - item was recorded. For example, the pattern (?(?=ab)ab) recorded "a" as a - first data item, and therefore matched "ca" after "c" instead of at the - start. - -11. Change 40 for 8.33 (allowing pcregrep to find empty strings) showed up a - bug that caused the command "echo a | ./pcregrep -M '|a'" to loop. - -12. The source of pcregrep now includes z/OS-specific code so that it can be - compiled for z/OS as part of the special z/OS distribution. - -13. Added the -T and -TM options to pcretest. - -14. The code in pcre_compile.c for creating the table of named capturing groups - has been refactored. Instead of creating the table dynamically during the - actual compiling pass, the information is remembered during the pre-compile - pass (on the stack unless there are more than 20 named groups, in which - case malloc() is used) and the whole table is created before the actual - compile happens. This has simplified the code (it is now nearly 150 lines - shorter) and prepared the way for better handling of references to groups - with duplicate names. - -15. A back reference to a named subpattern when there is more than one of the - same name now checks them in the order in which they appear in the pattern. - The first one that is set is used for the reference. Previously only the - first one was inspected. This change makes PCRE more compatible with Perl. - -16. Unicode character properties were updated from Unicode 6.3.0. - -17. The compile-time code for auto-possessification has been refactored, based - on a patch by Zoltan Herczeg. It now happens after instead of during - compilation. The code is cleaner, and more cases are handled. The option - PCRE_NO_AUTO_POSSESS is added for testing purposes, and the -O and /O - options in pcretest are provided to set it. It can also be set by - (*NO_AUTO_POSSESS) at the start of a pattern. - -18. The character VT has been added to the default ("C" locale) set of - characters that match \s and are generally treated as white space, - following this same change in Perl 5.18. There is now no difference between - "Perl space" and "POSIX space". Whether VT is treated as white space in - other locales depends on the locale. - -19. The code for checking named groups as conditions, either for being set or - for being recursed, has been refactored (this is related to 14 and 15 - above). Processing unduplicated named groups should now be as fast at - numerical groups, and processing duplicated groups should be faster than - before. - -20. Two patches to the CMake build system, by Alexander Barkov: - - (1) Replace the "source" command by "." in CMakeLists.txt because - "source" is a bash-ism. - - (2) Add missing HAVE_STDINT_H and HAVE_INTTYPES_H to config-cmake.h.in; - without these the CMake build does not work on Solaris. - -21. Perl has changed its handling of \8 and \9. If there is no previously - encountered capturing group of those numbers, they are treated as the - literal characters 8 and 9 instead of a binary zero followed by the - literals. PCRE now does the same. - -22. Following Perl, added \o{} to specify codepoints in octal, making it - possible to specify values greater than 0777 and also making them - unambiguous. - -23. Perl now gives an error for missing closing braces after \x{... instead of - treating the string as literal. PCRE now does the same. - -24. RunTest used to grumble if an inappropriate test was selected explicitly, - but just skip it when running all tests. This make it awkward to run ranges - of tests when one of them was inappropriate. Now it just skips any - inappropriate tests, as it always did when running all tests. - -25. If PCRE_AUTO_CALLOUT and PCRE_UCP were set for a pattern that contained - character types such as \d or \w, too many callouts were inserted, and the - data that they returned was rubbish. - -26. In UCP mode, \s was not matching two of the characters that Perl matches, - namely NEL (U+0085) and MONGOLIAN VOWEL SEPARATOR (U+180E), though they - were matched by \h. The code has now been refactored so that the lists of - the horizontal and vertical whitespace characters used for \h and \v (which - are defined only in one place) are now also used for \s. - -27. Add JIT support for the 64 bit TileGX architecture. - Patch by Jiong Wang (Tilera Corporation). - -28. Possessive quantifiers for classes (both explicit and automatically - generated) now use special opcodes instead of wrapping in ONCE brackets. - -29. Whereas an item such as A{4}+ ignored the possessivenes of the quantifier - (because it's meaningless), this was not happening when PCRE_CASELESS was - set. Not wrong, but inefficient. - -30. Updated perltest.pl to add /u (force Unicode mode) when /W (use Unicode - properties for \w, \d, etc) is present in a test regex. Otherwise if the - test contains no characters greater than 255, Perl doesn't realise it - should be using Unicode semantics. - -31. Upgraded the handling of the POSIX classes [:graph:], [:print:], and - [:punct:] when PCRE_UCP is set so as to include the same characters as Perl - does in Unicode mode. - -32. Added the "forbid" facility to pcretest so that putting tests into the - wrong test files can sometimes be quickly detected. - -33. There is now a limit (default 250) on the depth of nesting of parentheses. - This limit is imposed to control the amount of system stack used at compile - time. It can be changed at build time by --with-parens-nest-limit=xxx or - the equivalent in CMake. - -34. Character classes such as [A-\d] or [a-[:digit:]] now cause compile-time - errors. Perl warns for these when in warning mode, but PCRE has no facility - for giving warnings. - -35. Change 34 for 8.13 allowed quantifiers on assertions, because Perl does. - However, this was not working for (?!) because it is optimized to (*FAIL), - for which PCRE does not allow quantifiers. The optimization is now disabled - when a quantifier follows (?!). I can't see any use for this, but it makes - things uniform. - -36. Perl no longer allows group names to start with digits, so I have made this - change also in PCRE. It simplifies the code a bit. - -37. In extended mode, Perl ignores spaces before a + that indicates a - possessive quantifier. PCRE allowed a space before the quantifier, but not - before the possessive +. It now does. - -38. The use of \K (reset reported match start) within a repeated possessive - group such as (a\Kb)*+ was not working. - -40. Document that the same character tables must be used at compile time and - run time, and that the facility to pass tables to pcre_exec() and - pcre_dfa_exec() is for use only with saved/restored patterns. - -41. Applied Jeff Trawick's patch CMakeLists.txt, which "provides two new - features for Builds with MSVC: - - 1. Support pcre.rc and/or pcreposix.rc (as is already done for MinGW - builds). The .rc files can be used to set FileDescription and many other - attributes. - - 2. Add an option (-DINSTALL_MSVC_PDB) to enable installation of .pdb files. - This allows higher-level build scripts which want .pdb files to avoid - hard-coding the exact files needed." - -42. Added support for [[:<:]] and [[:>:]] as used in the BSD POSIX library to - mean "start of word" and "end of word", respectively, as a transition aid. - -43. A minimizing repeat of a class containing codepoints greater than 255 in - non-UTF 16-bit or 32-bit modes caused an internal error when PCRE was - compiled to use the heap for recursion. - -44. Got rid of some compiler warnings for unused variables when UTF but not UCP - is configured. - - -Version 8.33 28-May-2013 ------------------------- - -1. Added 'U' to some constants that are compared to unsigned integers, to - avoid compiler signed/unsigned warnings. Added (int) casts to unsigned - variables that are added to signed variables, to ensure the result is - signed and can be negated. - -2. Applied patch by Daniel Richard G for quashing MSVC warnings to the - CMake config files. - -3. Revise the creation of config.h.generic so that all boolean macros are - #undefined, whereas non-boolean macros are #ifndef/#endif-ed. This makes - overriding via -D on the command line possible. - -4. Changing the definition of the variable "op" in pcre_exec.c from pcre_uchar - to unsigned int is reported to make a quite noticeable speed difference in - a specific Windows environment. Testing on Linux did also appear to show - some benefit (and it is clearly not harmful). Also fixed the definition of - Xop which should be unsigned. - -5. Related to (4), changing the definition of the intermediate variable cc - in repeated character loops from pcre_uchar to pcre_uint32 also gave speed - improvements. - -6. Fix forward search in JIT when link size is 3 or greater. Also removed some - unnecessary spaces. - -7. Adjust autogen.sh and configure.ac to lose warnings given by automake 1.12 - and later. - -8. Fix two buffer over read issues in 16 and 32 bit modes. Affects JIT only. - -9. Optimizing fast_forward_start_bits in JIT. - -10. Adding support for callouts in JIT, and fixing some issues revealed - during this work. Namely: - - (a) Unoptimized capturing brackets incorrectly reset on backtrack. - - (b) Minimum length was not checked before the matching is started. - -11. The value of capture_last that is passed to callouts was incorrect in some - cases when there was a capture on one path that was subsequently abandoned - after a backtrack. Also, the capture_last value is now reset after a - recursion, since all captures are also reset in this case. - -12. The interpreter no longer returns the "too many substrings" error in the - case when an overflowing capture is in a branch that is subsequently - abandoned after a backtrack. - -13. In the pathological case when an offset vector of size 2 is used, pcretest - now prints out the matched string after a yield of 0 or 1. - -14. Inlining subpatterns in recursions, when certain conditions are fulfilled. - Only supported by the JIT compiler at the moment. - -15. JIT compiler now supports 32 bit Macs thanks to Lawrence Velazquez. - -16. Partial matches now set offsets[2] to the "bumpalong" value, that is, the - offset of the starting point of the matching process, provided the offsets - vector is large enough. - -17. The \A escape now records a lookbehind value of 1, though its execution - does not actually inspect the previous character. This is to ensure that, - in partial multi-segment matching, at least one character from the old - segment is retained when a new segment is processed. Otherwise, if there - are no lookbehinds in the pattern, \A might match incorrectly at the start - of a new segment. - -18. Added some #ifdef __VMS code into pcretest.c to help VMS implementations. - -19. Redefined some pcre_uchar variables in pcre_exec.c as pcre_uint32; this - gives some modest performance improvement in 8-bit mode. - -20. Added the PCRE-specific property \p{Xuc} for matching characters that can - be expressed in certain programming languages using Universal Character - Names. - -21. Unicode validation has been updated in the light of Unicode Corrigendum #9, - which points out that "non characters" are not "characters that may not - appear in Unicode strings" but rather "characters that are reserved for - internal use and have only local meaning". - -22. When a pattern was compiled with automatic callouts (PCRE_AUTO_CALLOUT) and - there was a conditional group that depended on an assertion, if the - assertion was false, the callout that immediately followed the alternation - in the condition was skipped when pcre_exec() was used for matching. - -23. Allow an explicit callout to be inserted before an assertion that is the - condition for a conditional group, for compatibility with automatic - callouts, which always insert a callout at this point. - -24. In 8.31, (*COMMIT) was confined to within a recursive subpattern. Perl also - confines (*SKIP) and (*PRUNE) in the same way, and this has now been done. - -25. (*PRUNE) is now supported by the JIT compiler. - -26. Fix infinite loop when /(?<=(*SKIP)ac)a/ is matched against aa. - -27. Fix the case where there are two or more SKIPs with arguments that may be - ignored. - -28. (*SKIP) is now supported by the JIT compiler. - -29. (*THEN) is now supported by the JIT compiler. - -30. Update RunTest with additional test selector options. - -31. The way PCRE handles backtracking verbs has been changed in two ways. - - (1) Previously, in something like (*COMMIT)(*SKIP), COMMIT would override - SKIP. Now, PCRE acts on whichever backtracking verb is reached first by - backtracking. In some cases this makes it more Perl-compatible, but Perl's - rather obscure rules do not always do the same thing. - - (2) Previously, backtracking verbs were confined within assertions. This is - no longer the case for positive assertions, except for (*ACCEPT). Again, - this sometimes improves Perl compatibility, and sometimes does not. - -32. A number of tests that were in test 2 because Perl did things differently - have been moved to test 1, because either Perl or PCRE has changed, and - these tests are now compatible. - -32. Backtracking control verbs are now handled in the same way in JIT and - interpreter. - -33. An opening parenthesis in a MARK/PRUNE/SKIP/THEN name in a pattern that - contained a forward subroutine reference caused a compile error. - -34. Auto-detect and optimize limited repetitions in JIT. - -35. Implement PCRE_NEVER_UTF to lock out the use of UTF, in particular, - blocking (*UTF) etc. - -36. In the interpreter, maximizing pattern repetitions for characters and - character types now use tail recursion, which reduces stack usage. - -37. The value of the max lookbehind was not correctly preserved if a compiled - and saved regex was reloaded on a host of different endianness. - -38. Implemented (*LIMIT_MATCH) and (*LIMIT_RECURSION). As part of the extension - of the compiled pattern block, expand the flags field from 16 to 32 bits - because it was almost full. - -39. Try madvise first before posix_madvise. - -40. Change 7 for PCRE 7.9 made it impossible for pcregrep to find empty lines - with a pattern such as ^$. It has taken 4 years for anybody to notice! The - original change locked out all matches of empty strings. This has been - changed so that one match of an empty string per line is recognized. - Subsequent searches on the same line (for colouring or for --only-matching, - for example) do not recognize empty strings. - -41. Applied a user patch to fix a number of spelling mistakes in comments. - -42. Data lines longer than 65536 caused pcretest to crash. - -43. Clarified the data type for length and startoffset arguments for pcre_exec - and pcre_dfa_exec in the function-specific man pages, where they were - explicitly stated to be in bytes, never having been updated. I also added - some clarification to the pcreapi man page. - -44. A call to pcre_dfa_exec() with an output vector size less than 2 caused - a segmentation fault. - - -Version 8.32 30-November-2012 ------------------------------ - -1. Improved JIT compiler optimizations for first character search and single - character iterators. - -2. Supporting IBM XL C compilers for PPC architectures in the JIT compiler. - Patch by Daniel Richard G. - -3. Single character iterator optimizations in the JIT compiler. - -4. Improved JIT compiler optimizations for character ranges. - -5. Rename the "leave" variable names to "quit" to improve WinCE compatibility. - Reported by Giuseppe D'Angelo. - -6. The PCRE_STARTLINE bit, indicating that a match can occur only at the start - of a line, was being set incorrectly in cases where .* appeared inside - atomic brackets at the start of a pattern, or where there was a subsequent - *PRUNE or *SKIP. - -7. Improved instruction cache flush for POWER/PowerPC. - Patch by Daniel Richard G. - -8. Fixed a number of issues in pcregrep, making it more compatible with GNU - grep: - - (a) There is now no limit to the number of patterns to be matched. - - (b) An error is given if a pattern is too long. - - (c) Multiple uses of --exclude, --exclude-dir, --include, and --include-dir - are now supported. - - (d) --exclude-from and --include-from (multiple use) have been added. - - (e) Exclusions and inclusions now apply to all files and directories, not - just to those obtained from scanning a directory recursively. - - (f) Multiple uses of -f and --file-list are now supported. - - (g) In a Windows environment, the default for -d has been changed from - "read" (the GNU grep default) to "skip", because otherwise the presence - of a directory in the file list provokes an error. - - (h) The documentation has been revised and clarified in places. - -9. Improve the matching speed of capturing brackets. - -10. Changed the meaning of \X so that it now matches a Unicode extended - grapheme cluster. - -11. Patch by Daniel Richard G to the autoconf files to add a macro for sorting - out POSIX threads when JIT support is configured. - -12. Added support for PCRE_STUDY_EXTRA_NEEDED. - -13. In the POSIX wrapper regcomp() function, setting re_nsub field in the preg - structure could go wrong in environments where size_t is not the same size - as int. - -14. Applied user-supplied patch to pcrecpp.cc to allow PCRE_NO_UTF8_CHECK to be - set. - -15. The EBCDIC support had decayed; later updates to the code had included - explicit references to (e.g.) \x0a instead of CHAR_LF. There has been a - general tidy up of EBCDIC-related issues, and the documentation was also - not quite right. There is now a test that can be run on ASCII systems to - check some of the EBCDIC-related things (but is it not a full test). - -16. The new PCRE_STUDY_EXTRA_NEEDED option is now used by pcregrep, resulting - in a small tidy to the code. - -17. Fix JIT tests when UTF is disabled and both 8 and 16 bit mode are enabled. - -18. If the --only-matching (-o) option in pcregrep is specified multiple - times, each one causes appropriate output. For example, -o1 -o2 outputs the - substrings matched by the 1st and 2nd capturing parentheses. A separating - string can be specified by --om-separator (default empty). - -19. Improving the first n character searches. - -20. Turn case lists for horizontal and vertical white space into macros so that - they are defined only once. - -21. This set of changes together give more compatible Unicode case-folding - behaviour for characters that have more than one other case when UCP - support is available. - - (a) The Unicode property table now has offsets into a new table of sets of - three or more characters that are case-equivalent. The MultiStage2.py - script that generates these tables (the pcre_ucd.c file) now scans - CaseFolding.txt instead of UnicodeData.txt for character case - information. - - (b) The code for adding characters or ranges of characters to a character - class has been abstracted into a generalized function that also handles - case-independence. In UTF-mode with UCP support, this uses the new data - to handle characters with more than one other case. - - (c) A bug that is fixed as a result of (b) is that codepoints less than 256 - whose other case is greater than 256 are now correctly matched - caselessly. Previously, the high codepoint matched the low one, but not - vice versa. - - (d) The processing of \h, \H, \v, and \ in character classes now makes use - of the new class addition function, using character lists defined as - macros alongside the case definitions of 20 above. - - (e) Caseless back references now work with characters that have more than - one other case. - - (f) General caseless matching of characters with more than one other case - is supported. - -22. Unicode character properties were updated from Unicode 6.2.0 - -23. Improved CMake support under Windows. Patch by Daniel Richard G. - -24. Add support for 32-bit character strings, and UTF-32 - -25. Major JIT compiler update (code refactoring and bugfixing). - Experimental Sparc 32 support is added. - -26. Applied a modified version of Daniel Richard G's patch to create - pcre.h.generic and config.h.generic by "make" instead of in the - PrepareRelease script. - -27. Added a definition for CHAR_NULL (helpful for the z/OS port), and use it in - pcre_compile.c when checking for a zero character. - -28. Introducing a native interface for JIT. Through this interface, the compiled - machine code can be directly executed. The purpose of this interface is to - provide fast pattern matching, so several sanity checks are not performed. - However, feature tests are still performed. The new interface provides - 1.4x speedup compared to the old one. - -29. If pcre_exec() or pcre_dfa_exec() was called with a negative value for - the subject string length, the error given was PCRE_ERROR_BADOFFSET, which - was confusing. There is now a new error PCRE_ERROR_BADLENGTH for this case. - -30. In 8-bit UTF-8 mode, pcretest failed to give an error for data codepoints - greater than 0x7fffffff (which cannot be represented in UTF-8, even under - the "old" RFC 2279). Instead, it ended up passing a negative length to - pcre_exec(). - -31. Add support for GCC's visibility feature to hide internal functions. - -32. Running "pcretest -C pcre8" or "pcretest -C pcre16" gave a spurious error - "unknown -C option" after outputting 0 or 1. - -33. There is now support for generating a code coverage report for the test - suite in environments where gcc is the compiler and lcov is installed. This - is mainly for the benefit of the developers. - -34. If PCRE is built with --enable-valgrind, certain memory regions are marked - unaddressable using valgrind annotations, allowing valgrind to detect - invalid memory accesses. This is mainly for the benefit of the developers. - -25. (*UTF) can now be used to start a pattern in any of the three libraries. - -26. Give configure error if --enable-cpp but no C++ compiler found. - - -Version 8.31 06-July-2012 -------------------------- - -1. Fixing a wrong JIT test case and some compiler warnings. - -2. Removed a bashism from the RunTest script. - -3. Add a cast to pcre_exec.c to fix the warning "unary minus operator applied - to unsigned type, result still unsigned" that was given by an MS compiler - on encountering the code "-sizeof(xxx)". - -4. Partial matching support is added to the JIT compiler. - -5. Fixed several bugs concerned with partial matching of items that consist - of more than one character: - - (a) /^(..)\1/ did not partially match "aba" because checking references was - done on an "all or nothing" basis. This also applied to repeated - references. - - (b) \R did not give a hard partial match if \r was found at the end of the - subject. - - (c) \X did not give a hard partial match after matching one or more - characters at the end of the subject. - - (d) When newline was set to CRLF, a pattern such as /a$/ did not recognize - a partial match for the string "\r". - - (e) When newline was set to CRLF, the metacharacter "." did not recognize - a partial match for a CR character at the end of the subject string. - -6. If JIT is requested using /S++ or -s++ (instead of just /S+ or -s+) when - running pcretest, the text "(JIT)" added to the output whenever JIT is - actually used to run the match. - -7. Individual JIT compile options can be set in pcretest by following -s+[+] - or /S+[+] with a digit between 1 and 7. - -8. OP_NOT now supports any UTF character not just single-byte ones. - -9. (*MARK) control verb is now supported by the JIT compiler. - -10. The command "./RunTest list" lists the available tests without actually - running any of them. (Because I keep forgetting what they all are.) - -11. Add PCRE_INFO_MAXLOOKBEHIND. - -12. Applied a (slightly modified) user-supplied patch that improves performance - when the heap is used for recursion (compiled with --disable-stack-for- - recursion). Instead of malloc and free for each heap frame each time a - logical recursion happens, frames are retained on a chain and re-used where - possible. This sometimes gives as much as 30% improvement. - -13. As documented, (*COMMIT) is now confined to within a recursive subpattern - call. - -14. As documented, (*COMMIT) is now confined to within a positive assertion. - -15. It is now possible to link pcretest with libedit as an alternative to - libreadline. - -16. (*COMMIT) control verb is now supported by the JIT compiler. - -17. The Unicode data tables have been updated to Unicode 6.1.0. - -18. Added --file-list option to pcregrep. - -19. Added binary file support to pcregrep, including the -a, --binary-files, - -I, and --text options. - -20. The madvise function is renamed for posix_madvise for QNX compatibility - reasons. Fixed by Giuseppe D'Angelo. - -21. Fixed a bug for backward assertions with REVERSE 0 in the JIT compiler. - -22. Changed the option for creating symbolic links for 16-bit man pages from - -s to -sf so that re-installing does not cause issues. - -23. Support PCRE_NO_START_OPTIMIZE in JIT as (*MARK) support requires it. - -24. Fixed a very old bug in pcretest that caused errors with restarted DFA - matches in certain environments (the workspace was not being correctly - retained). Also added to pcre_dfa_exec() a simple plausibility check on - some of the workspace data at the beginning of a restart. - -25. \s*\R was auto-possessifying the \s* when it should not, whereas \S*\R - was not doing so when it should - probably a typo introduced by SVN 528 - (change 8.10/14). - -26. When PCRE_UCP was not set, \w+\x{c4} was incorrectly auto-possessifying the - \w+ when the character tables indicated that \x{c4} was a word character. - There were several related cases, all because the tests for doing a table - lookup were testing for characters less than 127 instead of 255. - -27. If a pattern contains capturing parentheses that are not used in a match, - their slots in the ovector are set to -1. For those that are higher than - any matched groups, this happens at the end of processing. In the case when - there were back references that the ovector was too small to contain - (causing temporary malloc'd memory to be used during matching), and the - highest capturing number was not used, memory off the end of the ovector - was incorrectly being set to -1. (It was using the size of the temporary - memory instead of the true size.) - -28. To catch bugs like 27 using valgrind, when pcretest is asked to specify an - ovector size, it uses memory at the end of the block that it has got. - -29. Check for an overlong MARK name and give an error at compile time. The - limit is 255 for the 8-bit library and 65535 for the 16-bit library. - -30. JIT compiler update. - -31. JIT is now supported on jailbroken iOS devices. Thanks for Ruiger - Rill for the patch. - -32. Put spaces around SLJIT_PRINT_D in the JIT compiler. Required by CXX11. - -33. Variable renamings in the PCRE-JIT compiler. No functionality change. - -34. Fixed typos in pcregrep: in two places there was SUPPORT_LIBZ2 instead of - SUPPORT_LIBBZ2. This caused a build problem when bzip2 but not gzip (zlib) - was enabled. - -35. Improve JIT code generation for greedy plus quantifier. - -36. When /((?:a?)*)*c/ or /((?>a?)*)*c/ was matched against "aac", it set group - 1 to "aa" instead of to an empty string. The bug affected repeated groups - that could potentially match an empty string. - -37. Optimizing single character iterators in JIT. - -38. Wide characters specified with \uxxxx in JavaScript mode are now subject to - the same checks as \x{...} characters in non-JavaScript mode. Specifically, - codepoints that are too big for the mode are faulted, and in a UTF mode, - disallowed codepoints are also faulted. - -39. If PCRE was compiled with UTF support, in three places in the DFA - matcher there was code that should only have been obeyed in UTF mode, but - was being obeyed unconditionally. In 8-bit mode this could cause incorrect - processing when bytes with values greater than 127 were present. In 16-bit - mode the bug would be provoked by values in the range 0xfc00 to 0xdc00. In - both cases the values are those that cannot be the first data item in a UTF - character. The three items that might have provoked this were recursions, - possessively repeated groups, and atomic groups. - -40. Ensure that libpcre is explicitly listed in the link commands for pcretest - and pcregrep, because some OS require shared objects to be explicitly - passed to ld, causing the link step to fail if they are not. - -41. There were two incorrect #ifdefs in pcre_study.c, meaning that, in 16-bit - mode, patterns that started with \h* or \R* might be incorrectly matched. - - -Version 8.30 04-February-2012 ------------------------------ - -1. Renamed "isnumber" as "is_a_number" because in some Mac environments this - name is defined in ctype.h. - -2. Fixed a bug in fixed-length calculation for lookbehinds that would show up - only in quite long subpatterns. - -3. Removed the function pcre_info(), which has been obsolete and deprecated - since it was replaced by pcre_fullinfo() in February 2000. - -4. For a non-anchored pattern, if (*SKIP) was given with a name that did not - match a (*MARK), and the match failed at the start of the subject, a - reference to memory before the start of the subject could occur. This bug - was introduced by fix 17 of release 8.21. - -5. A reference to an unset group with zero minimum repetition was giving - totally wrong answers (in non-JavaScript-compatibility mode). For example, - /(another)?(\1?)test/ matched against "hello world test". This bug was - introduced in release 8.13. - -6. Add support for 16-bit character strings (a large amount of work involving - many changes and refactorings). - -7. RunGrepTest failed on msys because \r\n was replaced by whitespace when the - command "pattern=`printf 'xxx\r\njkl'`" was run. The pattern is now taken - from a file. - -8. Ovector size of 2 is also supported by JIT based pcre_exec (the ovector size - rounding is not applied in this particular case). - -9. The invalid Unicode surrogate codepoints U+D800 to U+DFFF are now rejected - if they appear, or are escaped, in patterns. - -10. Get rid of a number of -Wunused-but-set-variable warnings. - -11. The pattern /(?=(*:x))(q|)/ matches an empty string, and returns the mark - "x". The similar pattern /(?=(*:x))((*:y)q|)/ did not return a mark at all. - Oddly, Perl behaves the same way. PCRE has been fixed so that this pattern - also returns the mark "x". This bug applied to capturing parentheses, - non-capturing parentheses, and atomic parentheses. It also applied to some - assertions. - -12. Stephen Kelly's patch to CMakeLists.txt allows it to parse the version - information out of configure.ac instead of relying on pcre.h.generic, which - is not stored in the repository. - -13. Applied Dmitry V. Levin's patch for a more portable method for linking with - -lreadline. - -14. ZH added PCRE_CONFIG_JITTARGET; added its output to pcretest -C. - -15. Applied Graycode's patch to put the top-level frame on the stack rather - than the heap when not using the stack for recursion. This gives a - performance improvement in many cases when recursion is not deep. - -16. Experimental code added to "pcretest -C" to output the stack frame size. - - -Version 8.21 12-Dec-2011 ------------------------- - -1. Updating the JIT compiler. - -2. JIT compiler now supports OP_NCREF, OP_RREF and OP_NRREF. New test cases - are added as well. - -3. Fix cache-flush issue on PowerPC (It is still an experimental JIT port). - PCRE_EXTRA_TABLES is not suported by JIT, and should be checked before - calling _pcre_jit_exec. Some extra comments are added. - -4. (*MARK) settings inside atomic groups that do not contain any capturing - parentheses, for example, (?>a(*:m)), were not being passed out. This bug - was introduced by change 18 for 8.20. - -5. Supporting of \x, \U and \u in JavaScript compatibility mode based on the - ECMA-262 standard. - -6. Lookbehinds such as (?<=a{2}b) that contained a fixed repetition were - erroneously being rejected as "not fixed length" if PCRE_CASELESS was set. - This bug was probably introduced by change 9 of 8.13. - -7. While fixing 6 above, I noticed that a number of other items were being - incorrectly rejected as "not fixed length". This arose partly because newer - opcodes had not been added to the fixed-length checking code. I have (a) - corrected the bug and added tests for these items, and (b) arranged for an - error to occur if an unknown opcode is encountered while checking for fixed - length instead of just assuming "not fixed length". The items that were - rejected were: (*ACCEPT), (*COMMIT), (*FAIL), (*MARK), (*PRUNE), (*SKIP), - (*THEN), \h, \H, \v, \V, and single character negative classes with fixed - repetitions, e.g. [^a]{3}, with and without PCRE_CASELESS. - -8. A possessively repeated conditional subpattern such as (?(?=c)c|d)++ was - being incorrectly compiled and would have given unpredicatble results. - -9. A possessively repeated subpattern with minimum repeat count greater than - one behaved incorrectly. For example, (A){2,}+ behaved as if it was - (A)(A)++ which meant that, after a subsequent mismatch, backtracking into - the first (A) could occur when it should not. - -10. Add a cast and remove a redundant test from the code. - -11. JIT should use pcre_malloc/pcre_free for allocation. - -12. Updated pcre-config so that it no longer shows -L/usr/lib, which seems - best practice nowadays, and helps with cross-compiling. (If the exec_prefix - is anything other than /usr, -L is still shown). - -13. In non-UTF-8 mode, \C is now supported in lookbehinds and DFA matching. - -14. Perl does not support \N without a following name in a [] class; PCRE now - also gives an error. - -15. If a forward reference was repeated with an upper limit of around 2000, - it caused the error "internal error: overran compiling workspace". The - maximum number of forward references (including repeats) was limited by the - internal workspace, and dependent on the LINK_SIZE. The code has been - rewritten so that the workspace expands (via pcre_malloc) if necessary, and - the default depends on LINK_SIZE. There is a new upper limit (for safety) - of around 200,000 forward references. While doing this, I also speeded up - the filling in of repeated forward references. - -16. A repeated forward reference in a pattern such as (a)(?2){2}(.) was - incorrectly expecting the subject to contain another "a" after the start. - -17. When (*SKIP:name) is activated without a corresponding (*MARK:name) earlier - in the match, the SKIP should be ignored. This was not happening; instead - the SKIP was being treated as NOMATCH. For patterns such as - /A(*MARK:A)A+(*SKIP:B)Z|AAC/ this meant that the AAC branch was never - tested. - -18. The behaviour of (*MARK), (*PRUNE), and (*THEN) has been reworked and is - now much more compatible with Perl, in particular in cases where the result - is a non-match for a non-anchored pattern. For example, if - /b(*:m)f|a(*:n)w/ is matched against "abc", the non-match returns the name - "m", where previously it did not return a name. A side effect of this - change is that for partial matches, the last encountered mark name is - returned, as for non matches. A number of tests that were previously not - Perl-compatible have been moved into the Perl-compatible test files. The - refactoring has had the pleasing side effect of removing one argument from - the match() function, thus reducing its stack requirements. - -19. If the /S+ option was used in pcretest to study a pattern using JIT, - subsequent uses of /S (without +) incorrectly behaved like /S+. - -21. Retrieve executable code size support for the JIT compiler and fixing - some warnings. - -22. A caseless match of a UTF-8 character whose other case uses fewer bytes did - not work when the shorter character appeared right at the end of the - subject string. - -23. Added some (int) casts to non-JIT modules to reduce warnings on 64-bit - systems. - -24. Added PCRE_INFO_JITSIZE to pass on the value from (21) above, and also - output it when the /M option is used in pcretest. - -25. The CheckMan script was not being included in the distribution. Also, added - an explicit "perl" to run Perl scripts from the PrepareRelease script - because this is reportedly needed in Windows. - -26. If study data was being save in a file and studying had not found a set of - "starts with" bytes for the pattern, the data written to the file (though - never used) was taken from uninitialized memory and so caused valgrind to - complain. - -27. Updated RunTest.bat as provided by Sheri Pierce. - -28. Fixed a possible uninitialized memory bug in pcre_jit_compile.c. - -29. Computation of memory usage for the table of capturing group names was - giving an unnecessarily large value. - - -Version 8.20 21-Oct-2011 ------------------------- - -1. Change 37 of 8.13 broke patterns like [:a]...[b:] because it thought it had - a POSIX class. After further experiments with Perl, which convinced me that - Perl has bugs and confusions, a closing square bracket is no longer allowed - in a POSIX name. This bug also affected patterns with classes that started - with full stops. - -2. If a pattern such as /(a)b|ac/ is matched against "ac", there is no - captured substring, but while checking the failing first alternative, - substring 1 is temporarily captured. If the output vector supplied to - pcre_exec() was not big enough for this capture, the yield of the function - was still zero ("insufficient space for captured substrings"). This cannot - be totally fixed without adding another stack variable, which seems a lot - of expense for a edge case. However, I have improved the situation in cases - such as /(a)(b)x|abc/ matched against "abc", where the return code - indicates that fewer than the maximum number of slots in the ovector have - been set. - -3. Related to (2) above: when there are more back references in a pattern than - slots in the output vector, pcre_exec() uses temporary memory during - matching, and copies in the captures as far as possible afterwards. It was - using the entire output vector, but this conflicts with the specification - that only 2/3 is used for passing back captured substrings. Now it uses - only the first 2/3, for compatibility. This is, of course, another edge - case. - -4. Zoltan Herczeg's just-in-time compiler support has been integrated into the - main code base, and can be used by building with --enable-jit. When this is - done, pcregrep automatically uses it unless --disable-pcregrep-jit or the - runtime --no-jit option is given. - -5. When the number of matches in a pcre_dfa_exec() run exactly filled the - ovector, the return from the function was zero, implying that there were - other matches that did not fit. The correct "exactly full" value is now - returned. - -6. If a subpattern that was called recursively or as a subroutine contained - (*PRUNE) or any other control that caused it to give a non-standard return, - invalid errors such as "Error -26 (nested recursion at the same subject - position)" or even infinite loops could occur. - -7. If a pattern such as /a(*SKIP)c|b(*ACCEPT)|/ was studied, it stopped - computing the minimum length on reaching *ACCEPT, and so ended up with the - wrong value of 1 rather than 0. Further investigation indicates that - computing a minimum subject length in the presence of *ACCEPT is difficult - (think back references, subroutine calls), and so I have changed the code - so that no minimum is registered for a pattern that contains *ACCEPT. - -8. If (*THEN) was present in the first (true) branch of a conditional group, - it was not handled as intended. [But see 16 below.] - -9. Replaced RunTest.bat and CMakeLists.txt with improved versions provided by - Sheri Pierce. - -10. A pathological pattern such as /(*ACCEPT)a/ was miscompiled, thinking that - the first byte in a match must be "a". - -11. Change 17 for 8.13 increased the recursion depth for patterns like - /a(?:.)*?a/ drastically. I've improved things by remembering whether a - pattern contains any instances of (*THEN). If it does not, the old - optimizations are restored. It would be nice to do this on a per-group - basis, but at the moment that is not feasible. - -12. In some environments, the output of pcretest -C is CRLF terminated. This - broke RunTest's code that checks for the link size. A single white space - character after the value is now allowed for. - -13. RunTest now checks for the "fr" locale as well as for "fr_FR" and "french". - For "fr", it uses the Windows-specific input and output files. - -14. If (*THEN) appeared in a group that was called recursively or as a - subroutine, it did not work as intended. [But see next item.] - -15. Consider the pattern /A (B(*THEN)C) | D/ where A, B, C, and D are complex - pattern fragments (but not containing any | characters). If A and B are - matched, but there is a failure in C so that it backtracks to (*THEN), PCRE - was behaving differently to Perl. PCRE backtracked into A, but Perl goes to - D. In other words, Perl considers parentheses that do not contain any | - characters to be part of a surrounding alternative, whereas PCRE was - treading (B(*THEN)C) the same as (B(*THEN)C|(*FAIL)) -- which Perl handles - differently. PCRE now behaves in the same way as Perl, except in the case - of subroutine/recursion calls such as (?1) which have in any case always - been different (but PCRE had them first :-). - -16. Related to 15 above: Perl does not treat the | in a conditional group as - creating alternatives. Such a group is treated in the same way as an - ordinary group without any | characters when processing (*THEN). PCRE has - been changed to match Perl's behaviour. - -17. If a user had set PCREGREP_COLO(U)R to something other than 1:31, the - RunGrepTest script failed. - -18. Change 22 for version 13 caused atomic groups to use more stack. This is - inevitable for groups that contain captures, but it can lead to a lot of - stack use in large patterns. The old behaviour has been restored for atomic - groups that do not contain any capturing parentheses. - -19. If the PCRE_NO_START_OPTIMIZE option was set for pcre_compile(), it did not - suppress the check for a minimum subject length at run time. (If it was - given to pcre_exec() or pcre_dfa_exec() it did work.) - -20. Fixed an ASCII-dependent infelicity in pcretest that would have made it - fail to work when decoding hex characters in data strings in EBCDIC - environments. - -21. It appears that in at least one Mac OS environment, the isxdigit() function - is implemented as a macro that evaluates to its argument more than once, - contravening the C 90 Standard (I haven't checked a later standard). There - was an instance in pcretest which caused it to go wrong when processing - \x{...} escapes in subject strings. The has been rewritten to avoid using - things like p++ in the argument of isxdigit(). - - -Version 8.13 16-Aug-2011 ------------------------- - -1. The Unicode data tables have been updated to Unicode 6.0.0. - -2. Two minor typos in pcre_internal.h have been fixed. - -3. Added #include <string.h> to pcre_scanner_unittest.cc, pcrecpp.cc, and - pcrecpp_unittest.cc. They are needed for strcmp(), memset(), and strchr() - in some environments (e.g. Solaris 10/SPARC using Sun Studio 12U2). - -4. There were a number of related bugs in the code for matching backrefences - caselessly in UTF-8 mode when codes for the characters concerned were - different numbers of bytes. For example, U+023A and U+2C65 are an upper - and lower case pair, using 2 and 3 bytes, respectively. The main bugs were: - (a) A reference to 3 copies of a 2-byte code matched only 2 of a 3-byte - code. (b) A reference to 2 copies of a 3-byte code would not match 2 of a - 2-byte code at the end of the subject (it thought there wasn't enough data - left). - -5. Comprehensive information about what went wrong is now returned by - pcre_exec() and pcre_dfa_exec() when the UTF-8 string check fails, as long - as the output vector has at least 2 elements. The offset of the start of - the failing character and a reason code are placed in the vector. - -6. When the UTF-8 string check fails for pcre_compile(), the offset that is - now returned is for the first byte of the failing character, instead of the - last byte inspected. This is an incompatible change, but I hope it is small - enough not to be a problem. It makes the returned offset consistent with - pcre_exec() and pcre_dfa_exec(). - -7. pcretest now gives a text phrase as well as the error number when - pcre_exec() or pcre_dfa_exec() fails; if the error is a UTF-8 check - failure, the offset and reason code are output. - -8. When \R was used with a maximizing quantifier it failed to skip backwards - over a \r\n pair if the subsequent match failed. Instead, it just skipped - back over a single character (\n). This seems wrong (because it treated the - two characters as a single entity when going forwards), conflicts with the - documentation that \R is equivalent to (?>\r\n|\n|...etc), and makes the - behaviour of \R* different to (\R)*, which also seems wrong. The behaviour - has been changed. - -9. Some internal refactoring has changed the processing so that the handling - of the PCRE_CASELESS and PCRE_MULTILINE options is done entirely at compile - time (the PCRE_DOTALL option was changed this way some time ago: version - 7.7 change 16). This has made it possible to abolish the OP_OPT op code, - which was always a bit of a fudge. It also means that there is one less - argument for the match() function, which reduces its stack requirements - slightly. This change also fixes an incompatibility with Perl: the pattern - (?i:([^b]))(?1) should not match "ab", but previously PCRE gave a match. - -10. More internal refactoring has drastically reduced the number of recursive - calls to match() for possessively repeated groups such as (abc)++ when - using pcre_exec(). - -11. While implementing 10, a number of bugs in the handling of groups were - discovered and fixed: - - (?<=(a)+) was not diagnosed as invalid (non-fixed-length lookbehind). - (a|)*(?1) gave a compile-time internal error. - ((a|)+)+ did not notice that the outer group could match an empty string. - (^a|^)+ was not marked as anchored. - (.*a|.*)+ was not marked as matching at start or after a newline. - -12. Yet more internal refactoring has removed another argument from the match() - function. Special calls to this function are now indicated by setting a - value in a variable in the "match data" data block. - -13. Be more explicit in pcre_study() instead of relying on "default" for - opcodes that mean there is no starting character; this means that when new - ones are added and accidentally left out of pcre_study(), testing should - pick them up. - -14. The -s option of pcretest has been documented for ages as being an old - synonym of -m (show memory usage). I have changed it to mean "force study - for every regex", that is, assume /S for every regex. This is similar to -i - and -d etc. It's slightly incompatible, but I'm hoping nobody is still - using it. It makes it easier to run collections of tests with and without - study enabled, and thereby test pcre_study() more easily. All the standard - tests are now run with and without -s (but some patterns can be marked as - "never study" - see 20 below). - -15. When (*ACCEPT) was used in a subpattern that was called recursively, the - restoration of the capturing data to the outer values was not happening - correctly. - -16. If a recursively called subpattern ended with (*ACCEPT) and matched an - empty string, and PCRE_NOTEMPTY was set, pcre_exec() thought the whole - pattern had matched an empty string, and so incorrectly returned a no - match. - -17. There was optimizing code for the last branch of non-capturing parentheses, - and also for the obeyed branch of a conditional subexpression, which used - tail recursion to cut down on stack usage. Unfortunately, now that there is - the possibility of (*THEN) occurring in these branches, tail recursion is - no longer possible because the return has to be checked for (*THEN). These - two optimizations have therefore been removed. [But see 8.20/11 above.] - -18. If a pattern containing \R was studied, it was assumed that \R always - matched two bytes, thus causing the minimum subject length to be - incorrectly computed because \R can also match just one byte. - -19. If a pattern containing (*ACCEPT) was studied, the minimum subject length - was incorrectly computed. - -20. If /S is present twice on a test pattern in pcretest input, it now - *disables* studying, thereby overriding the use of -s on the command line - (see 14 above). This is necessary for one or two tests to keep the output - identical in both cases. - -21. When (*ACCEPT) was used in an assertion that matched an empty string and - PCRE_NOTEMPTY was set, PCRE applied the non-empty test to the assertion. - -22. When an atomic group that contained a capturing parenthesis was - successfully matched, but the branch in which it appeared failed, the - capturing was not being forgotten if a higher numbered group was later - captured. For example, /(?>(a))b|(a)c/ when matching "ac" set capturing - group 1 to "a", when in fact it should be unset. This applied to multi- - branched capturing and non-capturing groups, repeated or not, and also to - positive assertions (capturing in negative assertions does not happen - in PCRE) and also to nested atomic groups. - -23. Add the ++ qualifier feature to pcretest, to show the remainder of the - subject after a captured substring, to make it easier to tell which of a - number of identical substrings has been captured. - -24. The way atomic groups are processed by pcre_exec() has been changed so that - if they are repeated, backtracking one repetition now resets captured - values correctly. For example, if ((?>(a+)b)+aabab) is matched against - "aaaabaaabaabab" the value of captured group 2 is now correctly recorded as - "aaa". Previously, it would have been "a". As part of this code - refactoring, the way recursive calls are handled has also been changed. - -25. If an assertion condition captured any substrings, they were not passed - back unless some other capturing happened later. For example, if - (?(?=(a))a) was matched against "a", no capturing was returned. - -26. When studying a pattern that contained subroutine calls or assertions, - the code for finding the minimum length of a possible match was handling - direct recursions such as (xxx(?1)|yyy) but not mutual recursions (where - group 1 called group 2 while simultaneously a separate group 2 called group - 1). A stack overflow occurred in this case. I have fixed this by limiting - the recursion depth to 10. - -27. Updated RunTest.bat in the distribution to the version supplied by Tom - Fortmann. This supports explicit test numbers on the command line, and has - argument validation and error reporting. - -28. An instance of \X with an unlimited repeat could fail if at any point the - first character it looked at was a mark character. - -29. Some minor code refactoring concerning Unicode properties and scripts - should reduce the stack requirement of match() slightly. - -30. Added the '=' option to pcretest to check the setting of unused capturing - slots at the end of the pattern, which are documented as being -1, but are - not included in the return count. - -31. If \k was not followed by a braced, angle-bracketed, or quoted name, PCRE - compiled something random. Now it gives a compile-time error (as does - Perl). - -32. A *MARK encountered during the processing of a positive assertion is now - recorded and passed back (compatible with Perl). - -33. If --only-matching or --colour was set on a pcregrep call whose pattern - had alternative anchored branches, the search for a second match in a line - was done as if at the line start. Thus, for example, /^01|^02/ incorrectly - matched the line "0102" twice. The same bug affected patterns that started - with a backwards assertion. For example /\b01|\b02/ also matched "0102" - twice. - -34. Previously, PCRE did not allow quantification of assertions. However, Perl - does, and because of capturing effects, quantifying parenthesized - assertions may at times be useful. Quantifiers are now allowed for - parenthesized assertions. - -35. A minor code tidy in pcre_compile() when checking options for \R usage. - -36. \g was being checked for fancy things in a character class, when it should - just be a literal "g". - -37. PCRE was rejecting [:a[:digit:]] whereas Perl was not. It seems that the - appearance of a nested POSIX class supersedes an apparent external class. - For example, [:a[:digit:]b:] matches "a", "b", ":", or a digit. Also, - unescaped square brackets may also appear as part of class names. For - example, [:a[:abc]b:] gives unknown class "[:abc]b:]". PCRE now behaves - more like Perl. (But see 8.20/1 above.) - -38. PCRE was giving an error for \N with a braced quantifier such as {1,} (this - was because it thought it was \N{name}, which is not supported). - -39. Add minix to OS list not supporting the -S option in pcretest. - -40. PCRE tries to detect cases of infinite recursion at compile time, but it - cannot analyze patterns in sufficient detail to catch mutual recursions - such as ((?1))((?2)). There is now a runtime test that gives an error if a - subgroup is called recursively as a subpattern for a second time at the - same position in the subject string. In previous releases this might have - been caught by the recursion limit, or it might have run out of stack. - -41. A pattern such as /(?(R)a+|(?R)b)/ is quite safe, as the recursion can - happen only once. PCRE was, however incorrectly giving a compile time error - "recursive call could loop indefinitely" because it cannot analyze the - pattern in sufficient detail. The compile time test no longer happens when - PCRE is compiling a conditional subpattern, but actual runaway loops are - now caught at runtime (see 40 above). - -42. It seems that Perl allows any characters other than a closing parenthesis - to be part of the NAME in (*MARK:NAME) and other backtracking verbs. PCRE - has been changed to be the same. - -43. Updated configure.ac to put in more quoting round AC_LANG_PROGRAM etc. so - as not to get warnings when autogen.sh is called. Also changed - AC_PROG_LIBTOOL (deprecated) to LT_INIT (the current macro). - -44. To help people who use pcregrep to scan files containing exceedingly long - lines, the following changes have been made: - - (a) The default value of the buffer size parameter has been increased from - 8K to 20K. (The actual buffer used is three times this size.) - - (b) The default can be changed by ./configure --with-pcregrep-bufsize when - PCRE is built. - - (c) A --buffer-size=n option has been added to pcregrep, to allow the size - to be set at run time. - - (d) Numerical values in pcregrep options can be followed by K or M, for - example --buffer-size=50K. - - (e) If a line being scanned overflows pcregrep's buffer, an error is now - given and the return code is set to 2. - -45. Add a pointer to the latest mark to the callout data block. - -46. The pattern /.(*F)/, when applied to "abc" with PCRE_PARTIAL_HARD, gave a - partial match of an empty string instead of no match. This was specific to - the use of ".". - -47. The pattern /f.*/8s, when applied to "for" with PCRE_PARTIAL_HARD, gave a - complete match instead of a partial match. This bug was dependent on both - the PCRE_UTF8 and PCRE_DOTALL options being set. - -48. For a pattern such as /\babc|\bdef/ pcre_study() was failing to set up the - starting byte set, because \b was not being ignored. - - -Version 8.12 15-Jan-2011 ------------------------- - -1. Fixed some typos in the markup of the man pages, and wrote a script that - checks for such things as part of the documentation building process. - -2. On a big-endian 64-bit system, pcregrep did not correctly process the - --match-limit and --recursion-limit options (added for 8.11). In - particular, this made one of the standard tests fail. (The integer value - went into the wrong half of a long int.) - -3. If the --colour option was given to pcregrep with -v (invert match), it - did strange things, either producing crazy output, or crashing. It should, - of course, ignore a request for colour when reporting lines that do not - match. - -4. Another pcregrep bug caused similar problems if --colour was specified with - -M (multiline) and the pattern match finished with a line ending. - -5. In pcregrep, when a pattern that ended with a literal newline sequence was - matched in multiline mode, the following line was shown as part of the - match. This seems wrong, so I have changed it. - -6. Another pcregrep bug in multiline mode, when --colour was specified, caused - the check for further matches in the same line (so they could be coloured) - to overrun the end of the current line. If another match was found, it was - incorrectly shown (and then shown again when found in the next line). - -7. If pcregrep was compiled under Windows, there was a reference to the - function pcregrep_exit() before it was defined. I am assuming this was - the cause of the "error C2371: 'pcregrep_exit' : redefinition;" that was - reported by a user. I've moved the definition above the reference. - - -Version 8.11 10-Dec-2010 ------------------------- - -1. (*THEN) was not working properly if there were untried alternatives prior - to it in the current branch. For example, in ((a|b)(*THEN)(*F)|c..) it - backtracked to try for "b" instead of moving to the next alternative branch - at the same level (in this case, to look for "c"). The Perl documentation - is clear that when (*THEN) is backtracked onto, it goes to the "next - alternative in the innermost enclosing group". - -2. (*COMMIT) was not overriding (*THEN), as it does in Perl. In a pattern - such as (A(*COMMIT)B(*THEN)C|D) any failure after matching A should - result in overall failure. Similarly, (*COMMIT) now overrides (*PRUNE) and - (*SKIP), (*SKIP) overrides (*PRUNE) and (*THEN), and (*PRUNE) overrides - (*THEN). - -3. If \s appeared in a character class, it removed the VT character from - the class, even if it had been included by some previous item, for example - in [\x00-\xff\s]. (This was a bug related to the fact that VT is not part - of \s, but is part of the POSIX "space" class.) - -4. A partial match never returns an empty string (because you can always - match an empty string at the end of the subject); however the checking for - an empty string was starting at the "start of match" point. This has been - changed to the "earliest inspected character" point, because the returned - data for a partial match starts at this character. This means that, for - example, /(?<=abc)def/ gives a partial match for the subject "abc" - (previously it gave "no match"). - -5. Changes have been made to the way PCRE_PARTIAL_HARD affects the matching - of $, \z, \Z, \b, and \B. If the match point is at the end of the string, - previously a full match would be given. However, setting PCRE_PARTIAL_HARD - has an implication that the given string is incomplete (because a partial - match is preferred over a full match). For this reason, these items now - give a partial match in this situation. [Aside: previously, the one case - /t\b/ matched against "cat" with PCRE_PARTIAL_HARD set did return a partial - match rather than a full match, which was wrong by the old rules, but is - now correct.] - -6. There was a bug in the handling of #-introduced comments, recognized when - PCRE_EXTENDED is set, when PCRE_NEWLINE_ANY and PCRE_UTF8 were also set. - If a UTF-8 multi-byte character included the byte 0x85 (e.g. +U0445, whose - UTF-8 encoding is 0xd1,0x85), this was misinterpreted as a newline when - scanning for the end of the comment. (*Character* 0x85 is an "any" newline, - but *byte* 0x85 is not, in UTF-8 mode). This bug was present in several - places in pcre_compile(). - -7. Related to (6) above, when pcre_compile() was skipping #-introduced - comments when looking ahead for named forward references to subpatterns, - the only newline sequence it recognized was NL. It now handles newlines - according to the set newline convention. - -8. SunOS4 doesn't have strerror() or strtoul(); pcregrep dealt with the - former, but used strtoul(), whereas pcretest avoided strtoul() but did not - cater for a lack of strerror(). These oversights have been fixed. - -9. Added --match-limit and --recursion-limit to pcregrep. - -10. Added two casts needed to build with Visual Studio when NO_RECURSE is set. - -11. When the -o option was used, pcregrep was setting a return code of 1, even - when matches were found, and --line-buffered was not being honoured. - -12. Added an optional parentheses number to the -o and --only-matching options - of pcregrep. - -13. Imitating Perl's /g action for multiple matches is tricky when the pattern - can match an empty string. The code to do it in pcretest and pcredemo - needed fixing: - - (a) When the newline convention was "crlf", pcretest got it wrong, skipping - only one byte after an empty string match just before CRLF (this case - just got forgotten; "any" and "anycrlf" were OK). - - (b) The pcretest code also had a bug, causing it to loop forever in UTF-8 - mode when an empty string match preceded an ASCII character followed by - a non-ASCII character. (The code for advancing by one character rather - than one byte was nonsense.) - - (c) The pcredemo.c sample program did not have any code at all to handle - the cases when CRLF is a valid newline sequence. - -14. Neither pcre_exec() nor pcre_dfa_exec() was checking that the value given - as a starting offset was within the subject string. There is now a new - error, PCRE_ERROR_BADOFFSET, which is returned if the starting offset is - negative or greater than the length of the string. In order to test this, - pcretest is extended to allow the setting of negative starting offsets. - -15. In both pcre_exec() and pcre_dfa_exec() the code for checking that the - starting offset points to the beginning of a UTF-8 character was - unnecessarily clumsy. I tidied it up. - -16. Added PCRE_ERROR_SHORTUTF8 to make it possible to distinguish between a - bad UTF-8 sequence and one that is incomplete when using PCRE_PARTIAL_HARD. - -17. Nobody had reported that the --include_dir option, which was added in - release 7.7 should have been called --include-dir (hyphen, not underscore) - for compatibility with GNU grep. I have changed it to --include-dir, but - left --include_dir as an undocumented synonym, and the same for - --exclude-dir, though that is not available in GNU grep, at least as of - release 2.5.4. - -18. At a user's suggestion, the macros GETCHAR and friends (which pick up UTF-8 - characters from a string of bytes) have been redefined so as not to use - loops, in order to improve performance in some environments. At the same - time, I abstracted some of the common code into auxiliary macros to save - repetition (this should not affect the compiled code). - -19. If \c was followed by a multibyte UTF-8 character, bad things happened. A - compile-time error is now given if \c is not followed by an ASCII - character, that is, a byte less than 128. (In EBCDIC mode, the code is - different, and any byte value is allowed.) - -20. Recognize (*NO_START_OPT) at the start of a pattern to set the PCRE_NO_ - START_OPTIMIZE option, which is now allowed at compile time - but just - passed through to pcre_exec() or pcre_dfa_exec(). This makes it available - to pcregrep and other applications that have no direct access to PCRE - options. The new /Y option in pcretest sets this option when calling - pcre_compile(). - -21. Change 18 of release 8.01 broke the use of named subpatterns for recursive - back references. Groups containing recursive back references were forced to - be atomic by that change, but in the case of named groups, the amount of - memory required was incorrectly computed, leading to "Failed: internal - error: code overflow". This has been fixed. - -22. Some patches to pcre_stringpiece.h, pcre_stringpiece_unittest.cc, and - pcretest.c, to avoid build problems in some Borland environments. - - -Version 8.10 25-Jun-2010 ------------------------- - -1. Added support for (*MARK:ARG) and for ARG additions to PRUNE, SKIP, and - THEN. - -2. (*ACCEPT) was not working when inside an atomic group. - -3. Inside a character class, \B is treated as a literal by default, but - faulted if PCRE_EXTRA is set. This mimics Perl's behaviour (the -w option - causes the error). The code is unchanged, but I tidied the documentation. - -4. Inside a character class, PCRE always treated \R and \X as literals, - whereas Perl faults them if its -w option is set. I have changed PCRE so - that it faults them when PCRE_EXTRA is set. - -5. Added support for \N, which always matches any character other than - newline. (It is the same as "." when PCRE_DOTALL is not set.) - -6. When compiling pcregrep with newer versions of gcc which may have - FORTIFY_SOURCE set, several warnings "ignoring return value of 'fwrite', - declared with attribute warn_unused_result" were given. Just casting the - result to (void) does not stop the warnings; a more elaborate fudge is - needed. I've used a macro to implement this. - -7. Minor change to pcretest.c to avoid a compiler warning. - -8. Added four artifical Unicode properties to help with an option to make - \s etc use properties (see next item). The new properties are: Xan - (alphanumeric), Xsp (Perl space), Xps (POSIX space), and Xwd (word). - -9. Added PCRE_UCP to make \b, \d, \s, \w, and certain POSIX character classes - use Unicode properties. (*UCP) at the start of a pattern can be used to set - this option. Modified pcretest to add /W to test this facility. Added - REG_UCP to make it available via the POSIX interface. - -10. Added --line-buffered to pcregrep. - -11. In UTF-8 mode, if a pattern that was compiled with PCRE_CASELESS was - studied, and the match started with a letter with a code point greater than - 127 whose first byte was different to the first byte of the other case of - the letter, the other case of this starting letter was not recognized - (#976). - -12. If a pattern that was studied started with a repeated Unicode property - test, for example, \p{Nd}+, there was the theoretical possibility of - setting up an incorrect bitmap of starting bytes, but fortunately it could - not have actually happened in practice until change 8 above was made (it - added property types that matched character-matching opcodes). - -13. pcre_study() now recognizes \h, \v, and \R when constructing a bit map of - possible starting bytes for non-anchored patterns. - -14. Extended the "auto-possessify" feature of pcre_compile(). It now recognizes - \R, and also a number of cases that involve Unicode properties, both - explicit and implicit when PCRE_UCP is set. - -15. If a repeated Unicode property match (e.g. \p{Lu}*) was used with non-UTF-8 - input, it could crash or give wrong results if characters with values - greater than 0xc0 were present in the subject string. (Detail: it assumed - UTF-8 input when processing these items.) - -16. Added a lot of (int) casts to avoid compiler warnings in systems where - size_t is 64-bit (#991). - -17. Added a check for running out of memory when PCRE is compiled with - --disable-stack-for-recursion (#990). - -18. If the last data line in a file for pcretest does not have a newline on - the end, a newline was missing in the output. - -19. The default pcre_chartables.c file recognizes only ASCII characters (values - less than 128) in its various bitmaps. However, there is a facility for - generating tables according to the current locale when PCRE is compiled. It - turns out that in some environments, 0x85 and 0xa0, which are Unicode space - characters, are recognized by isspace() and therefore were getting set in - these tables, and indeed these tables seem to approximate to ISO 8859. This - caused a problem in UTF-8 mode when pcre_study() was used to create a list - of bytes that can start a match. For \s, it was including 0x85 and 0xa0, - which of course cannot start UTF-8 characters. I have changed the code so - that only real ASCII characters (less than 128) and the correct starting - bytes for UTF-8 encodings are set for characters greater than 127 when in - UTF-8 mode. (When PCRE_UCP is set - see 9 above - the code is different - altogether.) - -20. Added the /T option to pcretest so as to be able to run tests with non- - standard character tables, thus making it possible to include the tests - used for 19 above in the standard set of tests. - -21. A pattern such as (?&t)(?#()(?(DEFINE)(?<t>a)) which has a forward - reference to a subpattern the other side of a comment that contains an - opening parenthesis caused either an internal compiling error, or a - reference to the wrong subpattern. - - -Version 8.02 19-Mar-2010 ------------------------- - -1. The Unicode data tables have been updated to Unicode 5.2.0. - -2. Added the option --libs-cpp to pcre-config, but only when C++ support is - configured. - -3. Updated the licensing terms in the pcregexp.pas file, as agreed with the - original author of that file, following a query about its status. - -4. On systems that do not have stdint.h (e.g. Solaris), check for and include - inttypes.h instead. This fixes a bug that was introduced by change 8.01/8. - -5. A pattern such as (?&t)*+(?(DEFINE)(?<t>.)) which has a possessive - quantifier applied to a forward-referencing subroutine call, could compile - incorrect code or give the error "internal error: previously-checked - referenced subpattern not found". - -6. Both MS Visual Studio and Symbian OS have problems with initializing - variables to point to external functions. For these systems, therefore, - pcre_malloc etc. are now initialized to local functions that call the - relevant global functions. - -7. There were two entries missing in the vectors called coptable and poptable - in pcre_dfa_exec.c. This could lead to memory accesses outsize the vectors. - I've fixed the data, and added a kludgy way of testing at compile time that - the lengths are correct (equal to the number of opcodes). - -8. Following on from 7, I added a similar kludge to check the length of the - eint vector in pcreposix.c. - -9. Error texts for pcre_compile() are held as one long string to avoid too - much relocation at load time. To find a text, the string is searched, - counting zeros. There was no check for running off the end of the string, - which could happen if a new error number was added without updating the - string. - -10. \K gave a compile-time error if it appeared in a lookbehind assersion. - -11. \K was not working if it appeared in an atomic group or in a group that - was called as a "subroutine", or in an assertion. Perl 5.11 documents that - \K is "not well defined" if used in an assertion. PCRE now accepts it if - the assertion is positive, but not if it is negative. - -12. Change 11 fortuitously reduced the size of the stack frame used in the - "match()" function of pcre_exec.c by one pointer. Forthcoming - implementation of support for (*MARK) will need an extra pointer on the - stack; I have reserved it now, so that the stack frame size does not - decrease. - -13. A pattern such as (?P<L1>(?P<L2>0)|(?P>L2)(?P>L1)) in which the only other - item in branch that calls a recursion is a subroutine call - as in the - second branch in the above example - was incorrectly given the compile- - time error "recursive call could loop indefinitely" because pcre_compile() - was not correctly checking the subroutine for matching a non-empty string. - -14. The checks for overrunning compiling workspace could trigger after an - overrun had occurred. This is a "should never occur" error, but it can be - triggered by pathological patterns such as hundreds of nested parentheses. - The checks now trigger 100 bytes before the end of the workspace. - -15. Fix typo in configure.ac: "srtoq" should be "strtoq". - - -Version 8.01 19-Jan-2010 ------------------------- - -1. If a pattern contained a conditional subpattern with only one branch (in - particular, this includes all (*DEFINE) patterns), a call to pcre_study() - computed the wrong minimum data length (which is of course zero for such - subpatterns). This could cause incorrect "no match" results. - -2. For patterns such as (?i)a(?-i)b|c where an option setting at the start of - the pattern is reset in the first branch, pcre_compile() failed with - "internal error: code overflow at offset...". This happened only when - the reset was to the original external option setting. (An optimization - abstracts leading options settings into an external setting, which was the - cause of this.) - -3. A pattern such as ^(?!a(*SKIP)b) where a negative assertion contained one - of the verbs SKIP, PRUNE, or COMMIT, did not work correctly. When the - assertion pattern did not match (meaning that the assertion was true), it - was incorrectly treated as false if the SKIP had been reached during the - matching. This also applied to assertions used as conditions. - -4. If an item that is not supported by pcre_dfa_exec() was encountered in an - assertion subpattern, including such a pattern used as a condition, - unpredictable results occurred, instead of the error return - PCRE_ERROR_DFA_UITEM. - -5. The C++ GlobalReplace function was not working like Perl for the special - situation when an empty string is matched. It now does the fancy magic - stuff that is necessary. - -6. In pcre_internal.h, obsolete includes to setjmp.h and stdarg.h have been - removed. (These were left over from very, very early versions of PCRE.) - -7. Some cosmetic changes to the code to make life easier when compiling it - as part of something else: - - (a) Change DEBUG to PCRE_DEBUG. - - (b) In pcre_compile(), rename the member of the "branch_chain" structure - called "current" as "current_branch", to prevent a collision with the - Linux macro when compiled as a kernel module. - - (c) In pcre_study(), rename the function set_bit() as set_table_bit(), to - prevent a collision with the Linux macro when compiled as a kernel - module. - -8. In pcre_compile() there are some checks for integer overflows that used to - cast potentially large values to (double). This has been changed to that - when building, a check for int64_t is made, and if it is found, it is used - instead, thus avoiding the use of floating point arithmetic. (There is no - other use of FP in PCRE.) If int64_t is not found, the fallback is to - double. - -9. Added two casts to avoid signed/unsigned warnings from VS Studio Express - 2005 (difference between two addresses compared to an unsigned value). - -10. Change the standard AC_CHECK_LIB test for libbz2 in configure.ac to a - custom one, because of the following reported problem in Windows: - - - libbz2 uses the Pascal calling convention (WINAPI) for the functions - under Win32. - - The standard autoconf AC_CHECK_LIB fails to include "bzlib.h", - therefore missing the function definition. - - The compiler thus generates a "C" signature for the test function. - - The linker fails to find the "C" function. - - PCRE fails to configure if asked to do so against libbz2. - -11. When running libtoolize from libtool-2.2.6b as part of autogen.sh, these - messages were output: - - Consider adding `AC_CONFIG_MACRO_DIR([m4])' to configure.ac and - rerunning libtoolize, to keep the correct libtool macros in-tree. - Consider adding `-I m4' to ACLOCAL_AMFLAGS in Makefile.am. - - I have done both of these things. - -12. Although pcre_dfa_exec() does not use nearly as much stack as pcre_exec() - most of the time, it *can* run out if it is given a pattern that contains a - runaway infinite recursion. I updated the discussion in the pcrestack man - page. - -13. Now that we have gone to the x.xx style of version numbers, the minor - version may start with zero. Using 08 or 09 is a bad idea because users - might check the value of PCRE_MINOR in their code, and 08 or 09 may be - interpreted as invalid octal numbers. I've updated the previous comment in - configure.ac, and also added a check that gives an error if 08 or 09 are - used. - -14. Change 8.00/11 was not quite complete: code had been accidentally omitted, - causing partial matching to fail when the end of the subject matched \W - in a UTF-8 pattern where \W was quantified with a minimum of 3. - -15. There were some discrepancies between the declarations in pcre_internal.h - of _pcre_is_newline(), _pcre_was_newline(), and _pcre_valid_utf8() and - their definitions. The declarations used "const uschar *" and the - definitions used USPTR. Even though USPTR is normally defined as "const - unsigned char *" (and uschar is typedeffed as "unsigned char"), it was - reported that: "This difference in casting confuses some C++ compilers, for - example, SunCC recognizes above declarations as different functions and - generates broken code for hbpcre." I have changed the declarations to use - USPTR. - -16. GNU libtool is named differently on some systems. The autogen.sh script now - tries several variants such as glibtoolize (MacOSX) and libtoolize1x - (FreeBSD). - -17. Applied Craig's patch that fixes an HP aCC compile error in pcre 8.00 - (strtoXX undefined when compiling pcrecpp.cc). The patch contains this - comment: "Figure out how to create a longlong from a string: strtoll and - equivalent. It's not enough to call AC_CHECK_FUNCS: hpux has a strtoll, for - instance, but it only takes 2 args instead of 3!" - -18. A subtle bug concerned with back references has been fixed by a change of - specification, with a corresponding code fix. A pattern such as - ^(xa|=?\1a)+$ which contains a back reference inside the group to which it - refers, was giving matches when it shouldn't. For example, xa=xaaa would - match that pattern. Interestingly, Perl (at least up to 5.11.3) has the - same bug. Such groups have to be quantified to be useful, or contained - inside another quantified group. (If there's no repetition, the reference - can never match.) The problem arises because, having left the group and - moved on to the rest of the pattern, a later failure that backtracks into - the group uses the captured value from the final iteration of the group - rather than the correct earlier one. I have fixed this in PCRE by forcing - any group that contains a reference to itself to be an atomic group; that - is, there cannot be any backtracking into it once it has completed. This is - similar to recursive and subroutine calls. - - -Version 8.00 19-Oct-09 ----------------------- - -1. The table for translating pcre_compile() error codes into POSIX error codes - was out-of-date, and there was no check on the pcre_compile() error code - being within the table. This could lead to an OK return being given in - error. - -2. Changed the call to open a subject file in pcregrep from fopen(pathname, - "r") to fopen(pathname, "rb"), which fixed a problem with some of the tests - in a Windows environment. - -3. The pcregrep --count option prints the count for each file even when it is - zero, as does GNU grep. However, pcregrep was also printing all files when - --files-with-matches was added. Now, when both options are given, it prints - counts only for those files that have at least one match. (GNU grep just - prints the file name in this circumstance, but including the count seems - more useful - otherwise, why use --count?) Also ensured that the - combination -clh just lists non-zero counts, with no names. - -4. The long form of the pcregrep -F option was incorrectly implemented as - --fixed_strings instead of --fixed-strings. This is an incompatible change, - but it seems right to fix it, and I didn't think it was worth preserving - the old behaviour. - -5. The command line items --regex=pattern and --regexp=pattern were not - recognized by pcregrep, which required --regex pattern or --regexp pattern - (with a space rather than an '='). The man page documented the '=' forms, - which are compatible with GNU grep; these now work. - -6. No libpcreposix.pc file was created for pkg-config; there was just - libpcre.pc and libpcrecpp.pc. The omission has been rectified. - -7. Added #ifndef SUPPORT_UCP into the pcre_ucd.c module, to reduce its size - when UCP support is not needed, by modifying the Python script that - generates it from Unicode data files. This should not matter if the module - is correctly used as a library, but I received one complaint about 50K of - unwanted data. My guess is that the person linked everything into his - program rather than using a library. Anyway, it does no harm. - -8. A pattern such as /\x{123}{2,2}+/8 was incorrectly compiled; the trigger - was a minimum greater than 1 for a wide character in a possessive - repetition. The same bug could also affect patterns like /(\x{ff}{0,2})*/8 - which had an unlimited repeat of a nested, fixed maximum repeat of a wide - character. Chaos in the form of incorrect output or a compiling loop could - result. - -9. The restrictions on what a pattern can contain when partial matching is - requested for pcre_exec() have been removed. All patterns can now be - partially matched by this function. In addition, if there are at least two - slots in the offset vector, the offset of the earliest inspected character - for the match and the offset of the end of the subject are set in them when - PCRE_ERROR_PARTIAL is returned. - -10. Partial matching has been split into two forms: PCRE_PARTIAL_SOFT, which is - synonymous with PCRE_PARTIAL, for backwards compatibility, and - PCRE_PARTIAL_HARD, which causes a partial match to supersede a full match, - and may be more useful for multi-segment matching. - -11. Partial matching with pcre_exec() is now more intuitive. A partial match - used to be given if ever the end of the subject was reached; now it is - given only if matching could not proceed because another character was - needed. This makes a difference in some odd cases such as Z(*FAIL) with the - string "Z", which now yields "no match" instead of "partial match". In the - case of pcre_dfa_exec(), "no match" is given if every matching path for the - final character ended with (*FAIL). - -12. Restarting a match using pcre_dfa_exec() after a partial match did not work - if the pattern had a "must contain" character that was already found in the - earlier partial match, unless partial matching was again requested. For - example, with the pattern /dog.(body)?/, the "must contain" character is - "g". If the first part-match was for the string "dog", restarting with - "sbody" failed. This bug has been fixed. - -13. The string returned by pcre_dfa_exec() after a partial match has been - changed so that it starts at the first inspected character rather than the - first character of the match. This makes a difference only if the pattern - starts with a lookbehind assertion or \b or \B (\K is not supported by - pcre_dfa_exec()). It's an incompatible change, but it makes the two - matching functions compatible, and I think it's the right thing to do. - -14. Added a pcredemo man page, created automatically from the pcredemo.c file, - so that the demonstration program is easily available in environments where - PCRE has not been installed from source. - -15. Arranged to add -DPCRE_STATIC to cflags in libpcre.pc, libpcreposix.cp, - libpcrecpp.pc and pcre-config when PCRE is not compiled as a shared - library. - -16. Added REG_UNGREEDY to the pcreposix interface, at the request of a user. - It maps to PCRE_UNGREEDY. It is not, of course, POSIX-compatible, but it - is not the first non-POSIX option to be added. Clearly some people find - these options useful. - -17. If a caller to the POSIX matching function regexec() passes a non-zero - value for nmatch with a NULL value for pmatch, the value of - nmatch is forced to zero. - -18. RunGrepTest did not have a test for the availability of the -u option of - the diff command, as RunTest does. It now checks in the same way as - RunTest, and also checks for the -b option. - -19. If an odd number of negated classes containing just a single character - interposed, within parentheses, between a forward reference to a named - subpattern and the definition of the subpattern, compilation crashed with - an internal error, complaining that it could not find the referenced - subpattern. An example of a crashing pattern is /(?&A)(([^m])(?<A>))/. - [The bug was that it was starting one character too far in when skipping - over the character class, thus treating the ] as data rather than - terminating the class. This meant it could skip too much.] - -20. Added PCRE_NOTEMPTY_ATSTART in order to be able to correctly implement the - /g option in pcretest when the pattern contains \K, which makes it possible - to have an empty string match not at the start, even when the pattern is - anchored. Updated pcretest and pcredemo to use this option. - -21. If the maximum number of capturing subpatterns in a recursion was greater - than the maximum at the outer level, the higher number was returned, but - with unset values at the outer level. The correct (outer level) value is - now given. - -22. If (*ACCEPT) appeared inside capturing parentheses, previous releases of - PCRE did not set those parentheses (unlike Perl). I have now found a way to - make it do so. The string so far is captured, making this feature - compatible with Perl. - -23. The tests have been re-organized, adding tests 11 and 12, to make it - possible to check the Perl 5.10 features against Perl 5.10. - -24. Perl 5.10 allows subroutine calls in lookbehinds, as long as the subroutine - pattern matches a fixed length string. PCRE did not allow this; now it - does. Neither allows recursion. - -25. I finally figured out how to implement a request to provide the minimum - length of subject string that was needed in order to match a given pattern. - (It was back references and recursion that I had previously got hung up - on.) This code has now been added to pcre_study(); it finds a lower bound - to the length of subject needed. It is not necessarily the greatest lower - bound, but using it to avoid searching strings that are too short does give - some useful speed-ups. The value is available to calling programs via - pcre_fullinfo(). - -26. While implementing 25, I discovered to my embarrassment that pcretest had - not been passing the result of pcre_study() to pcre_dfa_exec(), so the - study optimizations had never been tested with that matching function. - Oops. What is worse, even when it was passed study data, there was a bug in - pcre_dfa_exec() that meant it never actually used it. Double oops. There - were also very few tests of studied patterns with pcre_dfa_exec(). - -27. If (?| is used to create subpatterns with duplicate numbers, they are now - allowed to have the same name, even if PCRE_DUPNAMES is not set. However, - on the other side of the coin, they are no longer allowed to have different - names, because these cannot be distinguished in PCRE, and this has caused - confusion. (This is a difference from Perl.) - -28. When duplicate subpattern names are present (necessarily with different - numbers, as required by 27 above), and a test is made by name in a - conditional pattern, either for a subpattern having been matched, or for - recursion in such a pattern, all the associated numbered subpatterns are - tested, and the overall condition is true if the condition is true for any - one of them. This is the way Perl works, and is also more like the way - testing by number works. - - -Version 7.9 11-Apr-09 ---------------------- - -1. When building with support for bzlib/zlib (pcregrep) and/or readline - (pcretest), all targets were linked against these libraries. This included - libpcre, libpcreposix, and libpcrecpp, even though they do not use these - libraries. This caused unwanted dependencies to be created. This problem - has been fixed, and now only pcregrep is linked with bzlib/zlib and only - pcretest is linked with readline. - -2. The "typedef int BOOL" in pcre_internal.h that was included inside the - "#ifndef FALSE" condition by an earlier change (probably 7.8/18) has been - moved outside it again, because FALSE and TRUE are already defined in AIX, - but BOOL is not. - -3. The pcre_config() function was treating the PCRE_MATCH_LIMIT and - PCRE_MATCH_LIMIT_RECURSION values as ints, when they should be long ints. - -4. The pcregrep documentation said spaces were inserted as well as colons (or - hyphens) following file names and line numbers when outputting matching - lines. This is not true; no spaces are inserted. I have also clarified the - wording for the --colour (or --color) option. - -5. In pcregrep, when --colour was used with -o, the list of matching strings - was not coloured; this is different to GNU grep, so I have changed it to be - the same. - -6. When --colo(u)r was used in pcregrep, only the first matching substring in - each matching line was coloured. Now it goes on to look for further matches - of any of the test patterns, which is the same behaviour as GNU grep. - -7. A pattern that could match an empty string could cause pcregrep to loop; it - doesn't make sense to accept an empty string match in pcregrep, so I have - locked it out (using PCRE's PCRE_NOTEMPTY option). By experiment, this - seems to be how GNU grep behaves. [But see later change 40 for release - 8.33.] - -8. The pattern (?(?=.*b)b|^) was incorrectly compiled as "match must be at - start or after a newline", because the conditional assertion was not being - correctly handled. The rule now is that both the assertion and what follows - in the first alternative must satisfy the test. - -9. If auto-callout was enabled in a pattern with a conditional group whose - condition was an assertion, PCRE could crash during matching, both with - pcre_exec() and pcre_dfa_exec(). - -10. The PCRE_DOLLAR_ENDONLY option was not working when pcre_dfa_exec() was - used for matching. - -11. Unicode property support in character classes was not working for - characters (bytes) greater than 127 when not in UTF-8 mode. - -12. Added the -M command line option to pcretest. - -14. Added the non-standard REG_NOTEMPTY option to the POSIX interface. - -15. Added the PCRE_NO_START_OPTIMIZE match-time option. - -16. Added comments and documentation about mis-use of no_arg in the C++ - wrapper. - -17. Implemented support for UTF-8 encoding in EBCDIC environments, a patch - from Martin Jerabek that uses macro names for all relevant character and - string constants. - -18. Added to pcre_internal.h two configuration checks: (a) If both EBCDIC and - SUPPORT_UTF8 are set, give an error; (b) If SUPPORT_UCP is set without - SUPPORT_UTF8, define SUPPORT_UTF8. The "configure" script handles both of - these, but not everybody uses configure. - -19. A conditional group that had only one branch was not being correctly - recognized as an item that could match an empty string. This meant that an - enclosing group might also not be so recognized, causing infinite looping - (and probably a segfault) for patterns such as ^"((?(?=[a])[^"])|b)*"$ - with the subject "ab", where knowledge that the repeated group can match - nothing is needed in order to break the loop. - -20. If a pattern that was compiled with callouts was matched using pcre_dfa_ - exec(), but without supplying a callout function, matching went wrong. - -21. If PCRE_ERROR_MATCHLIMIT occurred during a recursion, there was a memory - leak if the size of the offset vector was greater than 30. When the vector - is smaller, the saved offsets during recursion go onto a local stack - vector, but for larger vectors malloc() is used. It was failing to free - when the recursion yielded PCRE_ERROR_MATCH_LIMIT (or any other "abnormal" - error, in fact). - -22. There was a missing #ifdef SUPPORT_UTF8 round one of the variables in the - heapframe that is used only when UTF-8 support is enabled. This caused no - problem, but was untidy. - -23. Steven Van Ingelgem's patch to CMakeLists.txt to change the name - CMAKE_BINARY_DIR to PROJECT_BINARY_DIR so that it works when PCRE is - included within another project. - -24. Steven Van Ingelgem's patches to add more options to the CMake support, - slightly modified by me: - - (a) PCRE_BUILD_TESTS can be set OFF not to build the tests, including - not building pcregrep. - - (b) PCRE_BUILD_PCREGREP can be see OFF not to build pcregrep, but only - if PCRE_BUILD_TESTS is also set OFF, because the tests use pcregrep. - -25. Forward references, both numeric and by name, in patterns that made use of - duplicate group numbers, could behave incorrectly or give incorrect errors, - because when scanning forward to find the reference group, PCRE was not - taking into account the duplicate group numbers. A pattern such as - ^X(?3)(a)(?|(b)|(q))(Y) is an example. - -26. Changed a few more instances of "const unsigned char *" to USPTR, making - the feature of a custom pointer more persuasive (as requested by a user). - -27. Wrapped the definitions of fileno and isatty for Windows, which appear in - pcretest.c, inside #ifndefs, because it seems they are sometimes already - pre-defined. - -28. Added support for (*UTF8) at the start of a pattern. - -29. Arrange for flags added by the "release type" setting in CMake to be shown - in the configuration summary. - - -Version 7.8 05-Sep-08 ---------------------- - -1. Replaced UCP searching code with optimized version as implemented for Ad - Muncher (http://www.admuncher.com/) by Peter Kankowski. This uses a two- - stage table and inline lookup instead of a function, giving speed ups of 2 - to 5 times on some simple patterns that I tested. Permission was given to - distribute the MultiStage2.py script that generates the tables (it's not in - the tarball, but is in the Subversion repository). - -2. Updated the Unicode datatables to Unicode 5.1.0. This adds yet more - scripts. - -3. Change 12 for 7.7 introduced a bug in pcre_study() when a pattern contained - a group with a zero qualifier. The result of the study could be incorrect, - or the function might crash, depending on the pattern. - -4. Caseless matching was not working for non-ASCII characters in back - references. For example, /(\x{de})\1/8i was not matching \x{de}\x{fe}. - It now works when Unicode Property Support is available. - -5. In pcretest, an escape such as \x{de} in the data was always generating - a UTF-8 string, even in non-UTF-8 mode. Now it generates a single byte in - non-UTF-8 mode. If the value is greater than 255, it gives a warning about - truncation. - -6. Minor bugfix in pcrecpp.cc (change "" == ... to NULL == ...). - -7. Added two (int) casts to pcregrep when printing the difference of two - pointers, in case they are 64-bit values. - -8. Added comments about Mac OS X stack usage to the pcrestack man page and to - test 2 if it fails. - -9. Added PCRE_CALL_CONVENTION just before the names of all exported functions, - and a #define of that name to empty if it is not externally set. This is to - allow users of MSVC to set it if necessary. - -10. The PCRE_EXP_DEFN macro which precedes exported functions was missing from - the convenience functions in the pcre_get.c source file. - -11. An option change at the start of a pattern that had top-level alternatives - could cause overwriting and/or a crash. This command provoked a crash in - some environments: - - printf "/(?i)[\xc3\xa9\xc3\xbd]|[\xc3\xa9\xc3\xbdA]/8\n" | pcretest - - This potential security problem was recorded as CVE-2008-2371. - -12. For a pattern where the match had to start at the beginning or immediately - after a newline (e.g /.*anything/ without the DOTALL flag), pcre_exec() and - pcre_dfa_exec() could read past the end of the passed subject if there was - no match. To help with detecting such bugs (e.g. with valgrind), I modified - pcretest so that it places the subject at the end of its malloc-ed buffer. - -13. The change to pcretest in 12 above threw up a couple more cases when pcre_ - exec() might read past the end of the data buffer in UTF-8 mode. - -14. A similar bug to 7.3/2 existed when the PCRE_FIRSTLINE option was set and - the data contained the byte 0x85 as part of a UTF-8 character within its - first line. This applied both to normal and DFA matching. - -15. Lazy qualifiers were not working in some cases in UTF-8 mode. For example, - /^[^d]*?$/8 failed to match "abc". - -16. Added a missing copyright notice to pcrecpp_internal.h. - -17. Make it more clear in the documentation that values returned from - pcre_exec() in ovector are byte offsets, not character counts. - -18. Tidied a few places to stop certain compilers from issuing warnings. - -19. Updated the Virtual Pascal + BCC files to compile the latest v7.7, as - supplied by Stefan Weber. I made a further small update for 7.8 because - there is a change of source arrangements: the pcre_searchfuncs.c module is - replaced by pcre_ucd.c. - - -Version 7.7 07-May-08 ---------------------- - -1. Applied Craig's patch to sort out a long long problem: "If we can't convert - a string to a long long, pretend we don't even have a long long." This is - done by checking for the strtoq, strtoll, and _strtoi64 functions. - -2. Applied Craig's patch to pcrecpp.cc to restore ABI compatibility with - pre-7.6 versions, which defined a global no_arg variable instead of putting - it in the RE class. (See also #8 below.) - -3. Remove a line of dead code, identified by coverity and reported by Nuno - Lopes. - -4. Fixed two related pcregrep bugs involving -r with --include or --exclude: - - (1) The include/exclude patterns were being applied to the whole pathnames - of files, instead of just to the final components. - - (2) If there was more than one level of directory, the subdirectories were - skipped unless they satisfied the include/exclude conditions. This is - inconsistent with GNU grep (and could even be seen as contrary to the - pcregrep specification - which I improved to make it absolutely clear). - The action now is always to scan all levels of directory, and just - apply the include/exclude patterns to regular files. - -5. Added the --include_dir and --exclude_dir patterns to pcregrep, and used - --exclude_dir in the tests to avoid scanning .svn directories. - -6. Applied Craig's patch to the QuoteMeta function so that it escapes the - NUL character as backslash + 0 rather than backslash + NUL, because PCRE - doesn't support NULs in patterns. - -7. Added some missing "const"s to declarations of static tables in - pcre_compile.c and pcre_dfa_exec.c. - -8. Applied Craig's patch to pcrecpp.cc to fix a problem in OS X that was - caused by fix #2 above. (Subsequently also a second patch to fix the - first patch. And a third patch - this was a messy problem.) - -9. Applied Craig's patch to remove the use of push_back(). - -10. Applied Alan Lehotsky's patch to add REG_STARTEND support to the POSIX - matching function regexec(). - -11. Added support for the Oniguruma syntax \g<name>, \g<n>, \g'name', \g'n', - which, however, unlike Perl's \g{...}, are subroutine calls, not back - references. PCRE supports relative numbers with this syntax (I don't think - Oniguruma does). - -12. Previously, a group with a zero repeat such as (...){0} was completely - omitted from the compiled regex. However, this means that if the group - was called as a subroutine from elsewhere in the pattern, things went wrong - (an internal error was given). Such groups are now left in the compiled - pattern, with a new opcode that causes them to be skipped at execution - time. - -13. Added the PCRE_JAVASCRIPT_COMPAT option. This makes the following changes - to the way PCRE behaves: - - (a) A lone ] character is dis-allowed (Perl treats it as data). - - (b) A back reference to an unmatched subpattern matches an empty string - (Perl fails the current match path). - - (c) A data ] in a character class must be notated as \] because if the - first data character in a class is ], it defines an empty class. (In - Perl it is not possible to have an empty class.) The empty class [] - never matches; it forces failure and is equivalent to (*FAIL) or (?!). - The negative empty class [^] matches any one character, independently - of the DOTALL setting. - -14. A pattern such as /(?2)[]a()b](abc)/ which had a forward reference to a - non-existent subpattern following a character class starting with ']' and - containing () gave an internal compiling error instead of "reference to - non-existent subpattern". Fortunately, when the pattern did exist, the - compiled code was correct. (When scanning forwards to check for the - existence of the subpattern, it was treating the data ']' as terminating - the class, so got the count wrong. When actually compiling, the reference - was subsequently set up correctly.) - -15. The "always fail" assertion (?!) is optimzed to (*FAIL) by pcre_compile; - it was being rejected as not supported by pcre_dfa_exec(), even though - other assertions are supported. I have made pcre_dfa_exec() support - (*FAIL). - -16. The implementation of 13c above involved the invention of a new opcode, - OP_ALLANY, which is like OP_ANY but doesn't check the /s flag. Since /s - cannot be changed at match time, I realized I could make a small - improvement to matching performance by compiling OP_ALLANY instead of - OP_ANY for "." when DOTALL was set, and then removing the runtime tests - on the OP_ANY path. - -17. Compiling pcretest on Windows with readline support failed without the - following two fixes: (1) Make the unistd.h include conditional on - HAVE_UNISTD_H; (2) #define isatty and fileno as _isatty and _fileno. - -18. Changed CMakeLists.txt and cmake/FindReadline.cmake to arrange for the - ncurses library to be included for pcretest when ReadLine support is - requested, but also to allow for it to be overridden. This patch came from - Daniel Bergström. - -19. There was a typo in the file ucpinternal.h where f0_rangeflag was defined - as 0x00f00000 instead of 0x00800000. Luckily, this would not have caused - any errors with the current Unicode tables. Thanks to Peter Kankowski for - spotting this. - - -Version 7.6 28-Jan-08 ---------------------- - -1. A character class containing a very large number of characters with - codepoints greater than 255 (in UTF-8 mode, of course) caused a buffer - overflow. - -2. Patch to cut out the "long long" test in pcrecpp_unittest when - HAVE_LONG_LONG is not defined. - -3. Applied Christian Ehrlicher's patch to update the CMake build files to - bring them up to date and include new features. This patch includes: - - - Fixed PH's badly added libz and libbz2 support. - - Fixed a problem with static linking. - - Added pcredemo. [But later removed - see 7 below.] - - Fixed dftables problem and added an option. - - Added a number of HAVE_XXX tests, including HAVE_WINDOWS_H and - HAVE_LONG_LONG. - - Added readline support for pcretest. - - Added an listing of the option settings after cmake has run. - -4. A user submitted a patch to Makefile that makes it easy to create - "pcre.dll" under mingw when using Configure/Make. I added stuff to - Makefile.am that cause it to include this special target, without - affecting anything else. Note that the same mingw target plus all - the other distribution libraries and programs are now supported - when configuring with CMake (see 6 below) instead of with - Configure/Make. - -5. Applied Craig's patch that moves no_arg into the RE class in the C++ code. - This is an attempt to solve the reported problem "pcrecpp::no_arg is not - exported in the Windows port". It has not yet been confirmed that the patch - solves the problem, but it does no harm. - -6. Applied Sheri's patch to CMakeLists.txt to add NON_STANDARD_LIB_PREFIX and - NON_STANDARD_LIB_SUFFIX for dll names built with mingw when configured - with CMake, and also correct the comment about stack recursion. - -7. Remove the automatic building of pcredemo from the ./configure system and - from CMakeLists.txt. The whole idea of pcredemo.c is that it is an example - of a program that users should build themselves after PCRE is installed, so - building it automatically is not really right. What is more, it gave - trouble in some build environments. - -8. Further tidies to CMakeLists.txt from Sheri and Christian. - - -Version 7.5 10-Jan-08 ---------------------- - -1. Applied a patch from Craig: "This patch makes it possible to 'ignore' - values in parens when parsing an RE using the C++ wrapper." - -2. Negative specials like \S did not work in character classes in UTF-8 mode. - Characters greater than 255 were excluded from the class instead of being - included. - -3. The same bug as (2) above applied to negated POSIX classes such as - [:^space:]. - -4. PCRECPP_STATIC was referenced in pcrecpp_internal.h, but nowhere was it - defined or documented. It seems to have been a typo for PCRE_STATIC, so - I have changed it. - -5. The construct (?&) was not diagnosed as a syntax error (it referenced the - first named subpattern) and a construct such as (?&a) would reference the - first named subpattern whose name started with "a" (in other words, the - length check was missing). Both these problems are fixed. "Subpattern name - expected" is now given for (?&) (a zero-length name), and this patch also - makes it give the same error for \k'' (previously it complained that that - was a reference to a non-existent subpattern). - -6. The erroneous patterns (?+-a) and (?-+a) give different error messages; - this is right because (?- can be followed by option settings as well as by - digits. I have, however, made the messages clearer. - -7. Patterns such as (?(1)a|b) (a pattern that contains fewer subpatterns - than the number used in the conditional) now cause a compile-time error. - This is actually not compatible with Perl, which accepts such patterns, but - treats the conditional as always being FALSE (as PCRE used to), but it - seems to me that giving a diagnostic is better. - -8. Change "alphameric" to the more common word "alphanumeric" in comments - and messages. - -9. Fix two occurrences of "backslash" in comments that should have been - "backspace". - -10. Remove two redundant lines of code that can never be obeyed (their function - was moved elsewhere). - -11. The program that makes PCRE's Unicode character property table had a bug - which caused it to generate incorrect table entries for sequences of - characters that have the same character type, but are in different scripts. - It amalgamated them into a single range, with the script of the first of - them. In other words, some characters were in the wrong script. There were - thirteen such cases, affecting characters in the following ranges: - - U+002b0 - U+002c1 - U+0060c - U+0060d - U+0061e - U+00612 - U+0064b - U+0065e - U+0074d - U+0076d - U+01800 - U+01805 - U+01d00 - U+01d77 - U+01d9b - U+01dbf - U+0200b - U+0200f - U+030fc - U+030fe - U+03260 - U+0327f - U+0fb46 - U+0fbb1 - U+10450 - U+1049d - -12. The -o option (show only the matching part of a line) for pcregrep was not - compatible with GNU grep in that, if there was more than one match in a - line, it showed only the first of them. It now behaves in the same way as - GNU grep. - -13. If the -o and -v options were combined for pcregrep, it printed a blank - line for every non-matching line. GNU grep prints nothing, and pcregrep now - does the same. The return code can be used to tell if there were any - non-matching lines. - -14. Added --file-offsets and --line-offsets to pcregrep. - -15. The pattern (?=something)(?R) was not being diagnosed as a potentially - infinitely looping recursion. The bug was that positive lookaheads were not - being skipped when checking for a possible empty match (negative lookaheads - and both kinds of lookbehind were skipped). - -16. Fixed two typos in the Windows-only code in pcregrep.c, and moved the - inclusion of <windows.h> to before rather than after the definition of - INVALID_FILE_ATTRIBUTES (patch from David Byron). - -17. Specifying a possessive quantifier with a specific limit for a Unicode - character property caused pcre_compile() to compile bad code, which led at - runtime to PCRE_ERROR_INTERNAL (-14). Examples of patterns that caused this - are: /\p{Zl}{2,3}+/8 and /\p{Cc}{2}+/8. It was the possessive "+" that - caused the error; without that there was no problem. - -18. Added --enable-pcregrep-libz and --enable-pcregrep-libbz2. - -19. Added --enable-pcretest-libreadline. - -20. In pcrecpp.cc, the variable 'count' was incremented twice in - RE::GlobalReplace(). As a result, the number of replacements returned was - double what it should be. I removed one of the increments, but Craig sent a - later patch that removed the other one (the right fix) and added unit tests - that check the return values (which was not done before). - -21. Several CMake things: - - (1) Arranged that, when cmake is used on Unix, the libraries end up with - the names libpcre and libpcreposix, not just pcre and pcreposix. - - (2) The above change means that pcretest and pcregrep are now correctly - linked with the newly-built libraries, not previously installed ones. - - (3) Added PCRE_SUPPORT_LIBREADLINE, PCRE_SUPPORT_LIBZ, PCRE_SUPPORT_LIBBZ2. - -22. In UTF-8 mode, with newline set to "any", a pattern such as .*a.*=.b.* - crashed when matching a string such as a\x{2029}b (note that \x{2029} is a - UTF-8 newline character). The key issue is that the pattern starts .*; - this means that the match must be either at the beginning, or after a - newline. The bug was in the code for advancing after a failed match and - checking that the new position followed a newline. It was not taking - account of UTF-8 characters correctly. - -23. PCRE was behaving differently from Perl in the way it recognized POSIX - character classes. PCRE was not treating the sequence [:...:] as a - character class unless the ... were all letters. Perl, however, seems to - allow any characters between [: and :], though of course it rejects as - unknown any "names" that contain non-letters, because all the known class - names consist only of letters. Thus, Perl gives an error for [[:1234:]], - for example, whereas PCRE did not - it did not recognize a POSIX character - class. This seemed a bit dangerous, so the code has been changed to be - closer to Perl. The behaviour is not identical to Perl, because PCRE will - diagnose an unknown class for, for example, [[:l\ower:]] where Perl will - treat it as [[:lower:]]. However, PCRE does now give "unknown" errors where - Perl does, and where it didn't before. - -24. Rewrite so as to remove the single use of %n from pcregrep because in some - Windows environments %n is disabled by default. - - -Version 7.4 21-Sep-07 ---------------------- - -1. Change 7.3/28 was implemented for classes by looking at the bitmap. This - means that a class such as [\s] counted as "explicit reference to CR or - LF". That isn't really right - the whole point of the change was to try to - help when there was an actual mention of one of the two characters. So now - the change happens only if \r or \n (or a literal CR or LF) character is - encountered. - -2. The 32-bit options word was also used for 6 internal flags, but the numbers - of both had grown to the point where there were only 3 bits left. - Fortunately, there was spare space in the data structure, and so I have - moved the internal flags into a new 16-bit field to free up more option - bits. - -3. The appearance of (?J) at the start of a pattern set the DUPNAMES option, - but did not set the internal JCHANGED flag - either of these is enough to - control the way the "get" function works - but the PCRE_INFO_JCHANGED - facility is supposed to tell if (?J) was ever used, so now (?J) at the - start sets both bits. - -4. Added options (at build time, compile time, exec time) to change \R from - matching any Unicode line ending sequence to just matching CR, LF, or CRLF. - -5. doc/pcresyntax.html was missing from the distribution. - -6. Put back the definition of PCRE_ERROR_NULLWSLIMIT, for backward - compatibility, even though it is no longer used. - -7. Added macro for snprintf to pcrecpp_unittest.cc and also for strtoll and - strtoull to pcrecpp.cc to select the available functions in WIN32 when the - windows.h file is present (where different names are used). [This was - reversed later after testing - see 16 below.] - -8. Changed all #include <config.h> to #include "config.h". There were also - some further <pcre.h> cases that I changed to "pcre.h". - -9. When pcregrep was used with the --colour option, it missed the line ending - sequence off the lines that it output. - -10. It was pointed out to me that arrays of string pointers cause lots of - relocations when a shared library is dynamically loaded. A technique of - using a single long string with a table of offsets can drastically reduce - these. I have refactored PCRE in four places to do this. The result is - dramatic: - - Originally: 290 - After changing UCP table: 187 - After changing error message table: 43 - After changing table of "verbs" 36 - After changing table of Posix names 22 - - Thanks to the folks working on Gregex for glib for this insight. - -11. --disable-stack-for-recursion caused compiling to fail unless -enable- - unicode-properties was also set. - -12. Updated the tests so that they work when \R is defaulted to ANYCRLF. - -13. Added checks for ANY and ANYCRLF to pcrecpp.cc where it previously - checked only for CRLF. - -14. Added casts to pcretest.c to avoid compiler warnings. - -15. Added Craig's patch to various pcrecpp modules to avoid compiler warnings. - -16. Added Craig's patch to remove the WINDOWS_H tests, that were not working, - and instead check for _strtoi64 explicitly, and avoid the use of snprintf() - entirely. This removes changes made in 7 above. - -17. The CMake files have been updated, and there is now more information about - building with CMake in the NON-UNIX-USE document. - - -Version 7.3 28-Aug-07 ---------------------- - - 1. In the rejigging of the build system that eventually resulted in 7.1, the - line "#include <pcre.h>" was included in pcre_internal.h. The use of angle - brackets there is not right, since it causes compilers to look for an - installed pcre.h, not the version that is in the source that is being - compiled (which of course may be different). I have changed it back to: - - #include "pcre.h" - - I have a vague recollection that the change was concerned with compiling in - different directories, but in the new build system, that is taken care of - by the VPATH setting the Makefile. - - 2. The pattern .*$ when run in not-DOTALL UTF-8 mode with newline=any failed - when the subject happened to end in the byte 0x85 (e.g. if the last - character was \x{1ec5}). *Character* 0x85 is one of the "any" newline - characters but of course it shouldn't be taken as a newline when it is part - of another character. The bug was that, for an unlimited repeat of . in - not-DOTALL UTF-8 mode, PCRE was advancing by bytes rather than by - characters when looking for a newline. - - 3. A small performance improvement in the DOTALL UTF-8 mode .* case. - - 4. Debugging: adjusted the names of opcodes for different kinds of parentheses - in debug output. - - 5. Arrange to use "%I64d" instead of "%lld" and "%I64u" instead of "%llu" for - long printing in the pcrecpp unittest when running under MinGW. - - 6. ESC_K was left out of the EBCDIC table. - - 7. Change 7.0/38 introduced a new limit on the number of nested non-capturing - parentheses; I made it 1000, which seemed large enough. Unfortunately, the - limit also applies to "virtual nesting" when a pattern is recursive, and in - this case 1000 isn't so big. I have been able to remove this limit at the - expense of backing off one optimization in certain circumstances. Normally, - when pcre_exec() would call its internal match() function recursively and - immediately return the result unconditionally, it uses a "tail recursion" - feature to save stack. However, when a subpattern that can match an empty - string has an unlimited repetition quantifier, it no longer makes this - optimization. That gives it a stack frame in which to save the data for - checking that an empty string has been matched. Previously this was taken - from the 1000-entry workspace that had been reserved. So now there is no - explicit limit, but more stack is used. - - 8. Applied Daniel's patches to solve problems with the import/export magic - syntax that is required for Windows, and which was going wrong for the - pcreposix and pcrecpp parts of the library. These were overlooked when this - problem was solved for the main library. - - 9. There were some crude static tests to avoid integer overflow when computing - the size of patterns that contain repeated groups with explicit upper - limits. As the maximum quantifier is 65535, the maximum group length was - set at 30,000 so that the product of these two numbers did not overflow a - 32-bit integer. However, it turns out that people want to use groups that - are longer than 30,000 bytes (though not repeat them that many times). - Change 7.0/17 (the refactoring of the way the pattern size is computed) has - made it possible to implement the integer overflow checks in a much more - dynamic way, which I have now done. The artificial limitation on group - length has been removed - we now have only the limit on the total length of - the compiled pattern, which depends on the LINK_SIZE setting. - -10. Fixed a bug in the documentation for get/copy named substring when - duplicate names are permitted. If none of the named substrings are set, the - functions return PCRE_ERROR_NOSUBSTRING (7); the doc said they returned an - empty string. - -11. Because Perl interprets \Q...\E at a high level, and ignores orphan \E - instances, patterns such as [\Q\E] or [\E] or even [^\E] cause an error, - because the ] is interpreted as the first data character and the - terminating ] is not found. PCRE has been made compatible with Perl in this - regard. Previously, it interpreted [\Q\E] as an empty class, and [\E] could - cause memory overwriting. - -10. Like Perl, PCRE automatically breaks an unlimited repeat after an empty - string has been matched (to stop an infinite loop). It was not recognizing - a conditional subpattern that could match an empty string if that - subpattern was within another subpattern. For example, it looped when - trying to match (((?(1)X|))*) but it was OK with ((?(1)X|)*) where the - condition was not nested. This bug has been fixed. - -12. A pattern like \X?\d or \P{L}?\d in non-UTF-8 mode could cause a backtrack - past the start of the subject in the presence of bytes with the top bit - set, for example "\x8aBCD". - -13. Added Perl 5.10 experimental backtracking controls (*FAIL), (*F), (*PRUNE), - (*SKIP), (*THEN), (*COMMIT), and (*ACCEPT). - -14. Optimized (?!) to (*FAIL). - -15. Updated the test for a valid UTF-8 string to conform to the later RFC 3629. - This restricts code points to be within the range 0 to 0x10FFFF, excluding - the "low surrogate" sequence 0xD800 to 0xDFFF. Previously, PCRE allowed the - full range 0 to 0x7FFFFFFF, as defined by RFC 2279. Internally, it still - does: it's just the validity check that is more restrictive. - -16. Inserted checks for integer overflows during escape sequence (backslash) - processing, and also fixed erroneous offset values for syntax errors during - backslash processing. - -17. Fixed another case of looking too far back in non-UTF-8 mode (cf 12 above) - for patterns like [\PPP\x8a]{1,}\x80 with the subject "A\x80". - -18. An unterminated class in a pattern like (?1)\c[ with a "forward reference" - caused an overrun. - -19. A pattern like (?:[\PPa*]*){8,} which had an "extended class" (one with - something other than just ASCII characters) inside a group that had an - unlimited repeat caused a loop at compile time (while checking to see - whether the group could match an empty string). - -20. Debugging a pattern containing \p or \P could cause a crash. For example, - [\P{Any}] did so. (Error in the code for printing property names.) - -21. An orphan \E inside a character class could cause a crash. - -22. A repeated capturing bracket such as (A)? could cause a wild memory - reference during compilation. - -23. There are several functions in pcre_compile() that scan along a compiled - expression for various reasons (e.g. to see if it's fixed length for look - behind). There were bugs in these functions when a repeated \p or \P was - present in the pattern. These operators have additional parameters compared - with \d, etc, and these were not being taken into account when moving along - the compiled data. Specifically: - - (a) A item such as \p{Yi}{3} in a lookbehind was not treated as fixed - length. - - (b) An item such as \pL+ within a repeated group could cause crashes or - loops. - - (c) A pattern such as \p{Yi}+(\P{Yi}+)(?1) could give an incorrect - "reference to non-existent subpattern" error. - - (d) A pattern like (\P{Yi}{2}\277)? could loop at compile time. - -24. A repeated \S or \W in UTF-8 mode could give wrong answers when multibyte - characters were involved (for example /\S{2}/8g with "A\x{a3}BC"). - -25. Using pcregrep in multiline, inverted mode (-Mv) caused it to loop. - -26. Patterns such as [\P{Yi}A] which include \p or \P and just one other - character were causing crashes (broken optimization). - -27. Patterns such as (\P{Yi}*\277)* (group with possible zero repeat containing - \p or \P) caused a compile-time loop. - -28. More problems have arisen in unanchored patterns when CRLF is a valid line - break. For example, the unstudied pattern [\r\n]A does not match the string - "\r\nA" because change 7.0/46 below moves the current point on by two - characters after failing to match at the start. However, the pattern \nA - *does* match, because it doesn't start till \n, and if [\r\n]A is studied, - the same is true. There doesn't seem any very clean way out of this, but - what I have chosen to do makes the common cases work: PCRE now takes note - of whether there can be an explicit match for \r or \n anywhere in the - pattern, and if so, 7.0/46 no longer applies. As part of this change, - there's a new PCRE_INFO_HASCRORLF option for finding out whether a compiled - pattern has explicit CR or LF references. - -29. Added (*CR) etc for changing newline setting at start of pattern. - - -Version 7.2 19-Jun-07 ---------------------- - - 1. If the fr_FR locale cannot be found for test 3, try the "french" locale, - which is apparently normally available under Windows. - - 2. Re-jig the pcregrep tests with different newline settings in an attempt - to make them independent of the local environment's newline setting. - - 3. Add code to configure.ac to remove -g from the CFLAGS default settings. - - 4. Some of the "internals" tests were previously cut out when the link size - was not 2, because the output contained actual offsets. The recent new - "Z" feature of pcretest means that these can be cut out, making the tests - usable with all link sizes. - - 5. Implemented Stan Switzer's goto replacement for longjmp() when not using - stack recursion. This gives a massive performance boost under BSD, but just - a small improvement under Linux. However, it saves one field in the frame - in all cases. - - 6. Added more features from the forthcoming Perl 5.10: - - (a) (?-n) (where n is a string of digits) is a relative subroutine or - recursion call. It refers to the nth most recently opened parentheses. - - (b) (?+n) is also a relative subroutine call; it refers to the nth next - to be opened parentheses. - - (c) Conditions that refer to capturing parentheses can be specified - relatively, for example, (?(-2)... or (?(+3)... - - (d) \K resets the start of the current match so that everything before - is not part of it. - - (e) \k{name} is synonymous with \k<name> and \k'name' (.NET compatible). - - (f) \g{name} is another synonym - part of Perl 5.10's unification of - reference syntax. - - (g) (?| introduces a group in which the numbering of parentheses in each - alternative starts with the same number. - - (h) \h, \H, \v, and \V match horizontal and vertical whitespace. - - 7. Added two new calls to pcre_fullinfo(): PCRE_INFO_OKPARTIAL and - PCRE_INFO_JCHANGED. - - 8. A pattern such as (.*(.)?)* caused pcre_exec() to fail by either not - terminating or by crashing. Diagnosed by Viktor Griph; it was in the code - for detecting groups that can match an empty string. - - 9. A pattern with a very large number of alternatives (more than several - hundred) was running out of internal workspace during the pre-compile - phase, where pcre_compile() figures out how much memory will be needed. A - bit of new cunning has reduced the workspace needed for groups with - alternatives. The 1000-alternative test pattern now uses 12 bytes of - workspace instead of running out of the 4096 that are available. - -10. Inserted some missing (unsigned int) casts to get rid of compiler warnings. - -11. Applied patch from Google to remove an optimization that didn't quite work. - The report of the bug said: - - pcrecpp::RE("a*").FullMatch("aaa") matches, while - pcrecpp::RE("a*?").FullMatch("aaa") does not, and - pcrecpp::RE("a*?\\z").FullMatch("aaa") does again. - -12. If \p or \P was used in non-UTF-8 mode on a character greater than 127 - it matched the wrong number of bytes. - - -Version 7.1 24-Apr-07 ---------------------- - - 1. Applied Bob Rossi and Daniel G's patches to convert the build system to one - that is more "standard", making use of automake and other Autotools. There - is some re-arrangement of the files and adjustment of comments consequent - on this. - - 2. Part of the patch fixed a problem with the pcregrep tests. The test of -r - for recursive directory scanning broke on some systems because the files - are not scanned in any specific order and on different systems the order - was different. A call to "sort" has been inserted into RunGrepTest for the - approprate test as a short-term fix. In the longer term there may be an - alternative. - - 3. I had an email from Eric Raymond about problems translating some of PCRE's - man pages to HTML (despite the fact that I distribute HTML pages, some - people do their own conversions for various reasons). The problems - concerned the use of low-level troff macros .br and .in. I have therefore - removed all such uses from the man pages (some were redundant, some could - be replaced by .nf/.fi pairs). The 132html script that I use to generate - HTML has been updated to handle .nf/.fi and to complain if it encounters - .br or .in. - - 4. Updated comments in configure.ac that get placed in config.h.in and also - arranged for config.h to be included in the distribution, with the name - config.h.generic, for the benefit of those who have to compile without - Autotools (compare pcre.h, which is now distributed as pcre.h.generic). - - 5. Updated the support (such as it is) for Virtual Pascal, thanks to Stefan - Weber: (1) pcre_internal.h was missing some function renames; (2) updated - makevp.bat for the current PCRE, using the additional files - makevp_c.txt, makevp_l.txt, and pcregexp.pas. - - 6. A Windows user reported a minor discrepancy with test 2, which turned out - to be caused by a trailing space on an input line that had got lost in his - copy. The trailing space was an accident, so I've just removed it. - - 7. Add -Wl,-R... flags in pcre-config.in for *BSD* systems, as I'm told - that is needed. - - 8. Mark ucp_table (in ucptable.h) and ucp_gentype (in pcre_ucp_searchfuncs.c) - as "const" (a) because they are and (b) because it helps the PHP - maintainers who have recently made a script to detect big data structures - in the php code that should be moved to the .rodata section. I remembered - to update Builducptable as well, so it won't revert if ucptable.h is ever - re-created. - - 9. Added some extra #ifdef SUPPORT_UTF8 conditionals into pcretest.c, - pcre_printint.src, pcre_compile.c, pcre_study.c, and pcre_tables.c, in - order to be able to cut out the UTF-8 tables in the latter when UTF-8 - support is not required. This saves 1.5-2K of code, which is important in - some applications. - - Later: more #ifdefs are needed in pcre_ord2utf8.c and pcre_valid_utf8.c - so as not to refer to the tables, even though these functions will never be - called when UTF-8 support is disabled. Otherwise there are problems with a - shared library. - -10. Fixed two bugs in the emulated memmove() function in pcre_internal.h: - - (a) It was defining its arguments as char * instead of void *. - - (b) It was assuming that all moves were upwards in memory; this was true - a long time ago when I wrote it, but is no longer the case. - - The emulated memove() is provided for those environments that have neither - memmove() nor bcopy(). I didn't think anyone used it these days, but that - is clearly not the case, as these two bugs were recently reported. - -11. The script PrepareRelease is now distributed: it calls 132html, CleanTxt, - and Detrail to create the HTML documentation, the .txt form of the man - pages, and it removes trailing spaces from listed files. It also creates - pcre.h.generic and config.h.generic from pcre.h and config.h. In the latter - case, it wraps all the #defines with #ifndefs. This script should be run - before "make dist". - -12. Fixed two fairly obscure bugs concerned with quantified caseless matching - with Unicode property support. - - (a) For a maximizing quantifier, if the two different cases of the - character were of different lengths in their UTF-8 codings (there are - some cases like this - I found 11), and the matching function had to - back up over a mixture of the two cases, it incorrectly assumed they - were both the same length. - - (b) When PCRE was configured to use the heap rather than the stack for - recursion during matching, it was not correctly preserving the data for - the other case of a UTF-8 character when checking ahead for a match - while processing a minimizing repeat. If the check also involved - matching a wide character, but failed, corruption could cause an - erroneous result when trying to check for a repeat of the original - character. - -13. Some tidying changes to the testing mechanism: - - (a) The RunTest script now detects the internal link size and whether there - is UTF-8 and UCP support by running ./pcretest -C instead of relying on - values substituted by "configure". (The RunGrepTest script already did - this for UTF-8.) The configure.ac script no longer substitutes the - relevant variables. - - (b) The debugging options /B and /D in pcretest show the compiled bytecode - with length and offset values. This means that the output is different - for different internal link sizes. Test 2 is skipped for link sizes - other than 2 because of this, bypassing the problem. Unfortunately, - there was also a test in test 3 (the locale tests) that used /B and - failed for link sizes other than 2. Rather than cut the whole test out, - I have added a new /Z option to pcretest that replaces the length and - offset values with spaces. This is now used to make test 3 independent - of link size. (Test 2 will be tidied up later.) - -14. If erroroffset was passed as NULL to pcre_compile, it provoked a - segmentation fault instead of returning the appropriate error message. - -15. In multiline mode when the newline sequence was set to "any", the pattern - ^$ would give a match between the \r and \n of a subject such as "A\r\nB". - This doesn't seem right; it now treats the CRLF combination as the line - ending, and so does not match in that case. It's only a pattern such as ^$ - that would hit this one: something like ^ABC$ would have failed after \r - and then tried again after \r\n. - -16. Changed the comparison command for RunGrepTest from "diff -u" to "diff -ub" - in an attempt to make files that differ only in their line terminators - compare equal. This works on Linux. - -17. Under certain error circumstances pcregrep might try to free random memory - as it exited. This is now fixed, thanks to valgrind. - -19. In pcretest, if the pattern /(?m)^$/g<any> was matched against the string - "abc\r\n\r\n", it found an unwanted second match after the second \r. This - was because its rules for how to advance for /g after matching an empty - string at the end of a line did not allow for this case. They now check for - it specially. - -20. pcretest is supposed to handle patterns and data of any length, by - extending its buffers when necessary. It was getting this wrong when the - buffer for a data line had to be extended. - -21. Added PCRE_NEWLINE_ANYCRLF which is like ANY, but matches only CR, LF, or - CRLF as a newline sequence. - -22. Code for handling Unicode properties in pcre_dfa_exec() wasn't being cut - out by #ifdef SUPPORT_UCP. This did no harm, as it could never be used, but - I have nevertheless tidied it up. - -23. Added some casts to kill warnings from HP-UX ia64 compiler. - -24. Added a man page for pcre-config. - - -Version 7.0 19-Dec-06 ---------------------- - - 1. Fixed a signed/unsigned compiler warning in pcre_compile.c, shown up by - moving to gcc 4.1.1. - - 2. The -S option for pcretest uses setrlimit(); I had omitted to #include - sys/time.h, which is documented as needed for this function. It doesn't - seem to matter on Linux, but it showed up on some releases of OS X. - - 3. It seems that there are systems where bytes whose values are greater than - 127 match isprint() in the "C" locale. The "C" locale should be the - default when a C program starts up. In most systems, only ASCII printing - characters match isprint(). This difference caused the output from pcretest - to vary, making some of the tests fail. I have changed pcretest so that: - - (a) When it is outputting text in the compiled version of a pattern, bytes - other than 32-126 are always shown as hex escapes. - - (b) When it is outputting text that is a matched part of a subject string, - it does the same, unless a different locale has been set for the match - (using the /L modifier). In this case, it uses isprint() to decide. - - 4. Fixed a major bug that caused incorrect computation of the amount of memory - required for a compiled pattern when options that changed within the - pattern affected the logic of the preliminary scan that determines the - length. The relevant options are -x, and -i in UTF-8 mode. The result was - that the computed length was too small. The symptoms of this bug were - either the PCRE error "internal error: code overflow" from pcre_compile(), - or a glibc crash with a message such as "pcretest: free(): invalid next - size (fast)". Examples of patterns that provoked this bug (shown in - pcretest format) are: - - /(?-x: )/x - /(?x)(?-x: \s*#\s*)/ - /((?i)[\x{c0}])/8 - /(?i:[\x{c0}])/8 - - HOWEVER: Change 17 below makes this fix obsolete as the memory computation - is now done differently. - - 5. Applied patches from Google to: (a) add a QuoteMeta function to the C++ - wrapper classes; (b) implement a new function in the C++ scanner that is - more efficient than the old way of doing things because it avoids levels of - recursion in the regex matching; (c) add a paragraph to the documentation - for the FullMatch() function. - - 6. The escape sequence \n was being treated as whatever was defined as - "newline". Not only was this contrary to the documentation, which states - that \n is character 10 (hex 0A), but it also went horribly wrong when - "newline" was defined as CRLF. This has been fixed. - - 7. In pcre_dfa_exec.c the value of an unsigned integer (the variable called c) - was being set to -1 for the "end of line" case (supposedly a value that no - character can have). Though this value is never used (the check for end of - line is "zero bytes in current character"), it caused compiler complaints. - I've changed it to 0xffffffff. - - 8. In pcre_version.c, the version string was being built by a sequence of - C macros that, in the event of PCRE_PRERELEASE being defined as an empty - string (as it is for production releases) called a macro with an empty - argument. The C standard says the result of this is undefined. The gcc - compiler treats it as an empty string (which was what was wanted) but it is - reported that Visual C gives an error. The source has been hacked around to - avoid this problem. - - 9. On the advice of a Windows user, included <io.h> and <fcntl.h> in Windows - builds of pcretest, and changed the call to _setmode() to use _O_BINARY - instead of 0x8000. Made all the #ifdefs test both _WIN32 and WIN32 (not all - of them did). - -10. Originally, pcretest opened its input and output without "b"; then I was - told that "b" was needed in some environments, so it was added for release - 5.0 to both the input and output. (It makes no difference on Unix-like - systems.) Later I was told that it is wrong for the input on Windows. I've - now abstracted the modes into two macros, to make it easier to fiddle with - them, and removed "b" from the input mode under Windows. - -11. Added pkgconfig support for the C++ wrapper library, libpcrecpp. - -12. Added -help and --help to pcretest as an official way of being reminded - of the options. - -13. Removed some redundant semicolons after macro calls in pcrecpparg.h.in - and pcrecpp.cc because they annoy compilers at high warning levels. - -14. A bit of tidying/refactoring in pcre_exec.c in the main bumpalong loop. - -15. Fixed an occurrence of == in configure.ac that should have been = (shell - scripts are not C programs :-) and which was not noticed because it works - on Linux. - -16. pcretest is supposed to handle any length of pattern and data line (as one - line or as a continued sequence of lines) by extending its input buffer if - necessary. This feature was broken for very long pattern lines, leading to - a string of junk being passed to pcre_compile() if the pattern was longer - than about 50K. - -17. I have done a major re-factoring of the way pcre_compile() computes the - amount of memory needed for a compiled pattern. Previously, there was code - that made a preliminary scan of the pattern in order to do this. That was - OK when PCRE was new, but as the facilities have expanded, it has become - harder and harder to keep it in step with the real compile phase, and there - have been a number of bugs (see for example, 4 above). I have now found a - cunning way of running the real compile function in a "fake" mode that - enables it to compute how much memory it would need, while actually only - ever using a few hundred bytes of working memory and without too many - tests of the mode. This should make future maintenance and development - easier. A side effect of this work is that the limit of 200 on the nesting - depth of parentheses has been removed (though this was never a serious - limitation, I suspect). However, there is a downside: pcre_compile() now - runs more slowly than before (30% or more, depending on the pattern). I - hope this isn't a big issue. There is no effect on runtime performance. - -18. Fixed a minor bug in pcretest: if a pattern line was not terminated by a - newline (only possible for the last line of a file) and it was a - pattern that set a locale (followed by /Lsomething), pcretest crashed. - -19. Added additional timing features to pcretest. (1) The -tm option now times - matching only, not compiling. (2) Both -t and -tm can be followed, as a - separate command line item, by a number that specifies the number of - repeats to use when timing. The default is 50000; this gives better - precision, but takes uncomfortably long for very large patterns. - -20. Extended pcre_study() to be more clever in cases where a branch of a - subpattern has no definite first character. For example, (a*|b*)[cd] would - previously give no result from pcre_study(). Now it recognizes that the - first character must be a, b, c, or d. - -21. There was an incorrect error "recursive call could loop indefinitely" if - a subpattern (or the entire pattern) that was being tested for matching an - empty string contained only one non-empty item after a nested subpattern. - For example, the pattern (?>\x{100}*)\d(?R) provoked this error - incorrectly, because the \d was being skipped in the check. - -22. The pcretest program now has a new pattern option /B and a command line - option -b, which is equivalent to adding /B to every pattern. This causes - it to show the compiled bytecode, without the additional information that - -d shows. The effect of -d is now the same as -b with -i (and similarly, /D - is the same as /B/I). - -23. A new optimization is now able automatically to treat some sequences such - as a*b as a*+b. More specifically, if something simple (such as a character - or a simple class like \d) has an unlimited quantifier, and is followed by - something that cannot possibly match the quantified thing, the quantifier - is automatically "possessified". - -24. A recursive reference to a subpattern whose number was greater than 39 - went wrong under certain circumstances in UTF-8 mode. This bug could also - have affected the operation of pcre_study(). - -25. Realized that a little bit of performance could be had by replacing - (c & 0xc0) == 0xc0 with c >= 0xc0 when processing UTF-8 characters. - -26. Timing data from pcretest is now shown to 4 decimal places instead of 3. - -27. Possessive quantifiers such as a++ were previously implemented by turning - them into atomic groups such as ($>a+). Now they have their own opcodes, - which improves performance. This includes the automatically created ones - from 23 above. - -28. A pattern such as (?=(\w+))\1: which simulates an atomic group using a - lookahead was broken if it was not anchored. PCRE was mistakenly expecting - the first matched character to be a colon. This applied both to named and - numbered groups. - -29. The ucpinternal.h header file was missing its idempotency #ifdef. - -30. I was sent a "project" file called libpcre.a.dev which I understand makes - building PCRE on Windows easier, so I have included it in the distribution. - -31. There is now a check in pcretest against a ridiculously large number being - returned by pcre_exec() or pcre_dfa_exec(). If this happens in a /g or /G - loop, the loop is abandoned. - -32. Forward references to subpatterns in conditions such as (?(2)...) where - subpattern 2 is defined later cause pcre_compile() to search forwards in - the pattern for the relevant set of parentheses. This search went wrong - when there were unescaped parentheses in a character class, parentheses - escaped with \Q...\E, or parentheses in a #-comment in /x mode. - -33. "Subroutine" calls and backreferences were previously restricted to - referencing subpatterns earlier in the regex. This restriction has now - been removed. - -34. Added a number of extra features that are going to be in Perl 5.10. On the - whole, these are just syntactic alternatives for features that PCRE had - previously implemented using the Python syntax or my own invention. The - other formats are all retained for compatibility. - - (a) Named groups can now be defined as (?<name>...) or (?'name'...) as well - as (?P<name>...). The new forms, as well as being in Perl 5.10, are - also .NET compatible. - - (b) A recursion or subroutine call to a named group can now be defined as - (?&name) as well as (?P>name). - - (c) A backreference to a named group can now be defined as \k<name> or - \k'name' as well as (?P=name). The new forms, as well as being in Perl - 5.10, are also .NET compatible. - - (d) A conditional reference to a named group can now use the syntax - (?(<name>) or (?('name') as well as (?(name). - - (e) A "conditional group" of the form (?(DEFINE)...) can be used to define - groups (named and numbered) that are never evaluated inline, but can be - called as "subroutines" from elsewhere. In effect, the DEFINE condition - is always false. There may be only one alternative in such a group. - - (f) A test for recursion can be given as (?(R1).. or (?(R&name)... as well - as the simple (?(R). The condition is true only if the most recent - recursion is that of the given number or name. It does not search out - through the entire recursion stack. - - (g) The escape \gN or \g{N} has been added, where N is a positive or - negative number, specifying an absolute or relative reference. - -35. Tidied to get rid of some further signed/unsigned compiler warnings and - some "unreachable code" warnings. - -36. Updated the Unicode property tables to Unicode version 5.0.0. Amongst other - things, this adds five new scripts. - -37. Perl ignores orphaned \E escapes completely. PCRE now does the same. - There were also incompatibilities regarding the handling of \Q..\E inside - character classes, for example with patterns like [\Qa\E-\Qz\E] where the - hyphen was adjacent to \Q or \E. I hope I've cleared all this up now. - -38. Like Perl, PCRE detects when an indefinitely repeated parenthesized group - matches an empty string, and forcibly breaks the loop. There were bugs in - this code in non-simple cases. For a pattern such as ^(a()*)* matched - against aaaa the result was just "a" rather than "aaaa", for example. Two - separate and independent bugs (that affected different cases) have been - fixed. - -39. Refactored the code to abolish the use of different opcodes for small - capturing bracket numbers. This is a tidy that I avoided doing when I - removed the limit on the number of capturing brackets for 3.5 back in 2001. - The new approach is not only tidier, it makes it possible to reduce the - memory needed to fix the previous bug (38). - -40. Implemented PCRE_NEWLINE_ANY to recognize any of the Unicode newline - sequences (http://unicode.org/unicode/reports/tr18/) as "newline" when - processing dot, circumflex, or dollar metacharacters, or #-comments in /x - mode. - -41. Add \R to match any Unicode newline sequence, as suggested in the Unicode - report. - -42. Applied patch, originally from Ari Pollak, modified by Google, to allow - copy construction and assignment in the C++ wrapper. - -43. Updated pcregrep to support "--newline=any". In the process, I fixed a - couple of bugs that could have given wrong results in the "--newline=crlf" - case. - -44. Added a number of casts and did some reorganization of signed/unsigned int - variables following suggestions from Dair Grant. Also renamed the variable - "this" as "item" because it is a C++ keyword. - -45. Arranged for dftables to add - - #include "pcre_internal.h" - - to pcre_chartables.c because without it, gcc 4.x may remove the array - definition from the final binary if PCRE is built into a static library and - dead code stripping is activated. - -46. For an unanchored pattern, if a match attempt fails at the start of a - newline sequence, and the newline setting is CRLF or ANY, and the next two - characters are CRLF, advance by two characters instead of one. - - -Version 6.7 04-Jul-06 ---------------------- - - 1. In order to handle tests when input lines are enormously long, pcretest has - been re-factored so that it automatically extends its buffers when - necessary. The code is crude, but this _is_ just a test program. The - default size has been increased from 32K to 50K. - - 2. The code in pcre_study() was using the value of the re argument before - testing it for NULL. (Of course, in any sensible call of the function, it - won't be NULL.) - - 3. The memmove() emulation function in pcre_internal.h, which is used on - systems that lack both memmove() and bcopy() - that is, hardly ever - - was missing a "static" storage class specifier. - - 4. When UTF-8 mode was not set, PCRE looped when compiling certain patterns - containing an extended class (one that cannot be represented by a bitmap - because it contains high-valued characters or Unicode property items, e.g. - [\pZ]). Almost always one would set UTF-8 mode when processing such a - pattern, but PCRE should not loop if you do not (it no longer does). - [Detail: two cases were found: (a) a repeated subpattern containing an - extended class; (b) a recursive reference to a subpattern that followed a - previous extended class. It wasn't skipping over the extended class - correctly when UTF-8 mode was not set.] - - 5. A negated single-character class was not being recognized as fixed-length - in lookbehind assertions such as (?<=[^f]), leading to an incorrect - compile error "lookbehind assertion is not fixed length". - - 6. The RunPerlTest auxiliary script was showing an unexpected difference - between PCRE and Perl for UTF-8 tests. It turns out that it is hard to - write a Perl script that can interpret lines of an input file either as - byte characters or as UTF-8, which is what "perltest" was being required to - do for the non-UTF-8 and UTF-8 tests, respectively. Essentially what you - can't do is switch easily at run time between having the "use utf8;" pragma - or not. In the end, I fudged it by using the RunPerlTest script to insert - "use utf8;" explicitly for the UTF-8 tests. - - 7. In multiline (/m) mode, PCRE was matching ^ after a terminating newline at - the end of the subject string, contrary to the documentation and to what - Perl does. This was true of both matching functions. Now it matches only at - the start of the subject and immediately after *internal* newlines. - - 8. A call of pcre_fullinfo() from pcretest to get the option bits was passing - a pointer to an int instead of a pointer to an unsigned long int. This - caused problems on 64-bit systems. - - 9. Applied a patch from the folks at Google to pcrecpp.cc, to fix "another - instance of the 'standard' template library not being so standard". - -10. There was no check on the number of named subpatterns nor the maximum - length of a subpattern name. The product of these values is used to compute - the size of the memory block for a compiled pattern. By supplying a very - long subpattern name and a large number of named subpatterns, the size - computation could be caused to overflow. This is now prevented by limiting - the length of names to 32 characters, and the number of named subpatterns - to 10,000. - -11. Subpatterns that are repeated with specific counts have to be replicated in - the compiled pattern. The size of memory for this was computed from the - length of the subpattern and the repeat count. The latter is limited to - 65535, but there was no limit on the former, meaning that integer overflow - could in principle occur. The compiled length of a repeated subpattern is - now limited to 30,000 bytes in order to prevent this. - -12. Added the optional facility to have named substrings with the same name. - -13. Added the ability to use a named substring as a condition, using the - Python syntax: (?(name)yes|no). This overloads (?(R)... and names that - are numbers (not recommended). Forward references are permitted. - -14. Added forward references in named backreferences (if you see what I mean). - -15. In UTF-8 mode, with the PCRE_DOTALL option set, a quantified dot in the - pattern could run off the end of the subject. For example, the pattern - "(?s)(.{1,5})"8 did this with the subject "ab". - -16. If PCRE_DOTALL or PCRE_MULTILINE were set, pcre_dfa_exec() behaved as if - PCRE_CASELESS was set when matching characters that were quantified with ? - or *. - -17. A character class other than a single negated character that had a minimum - but no maximum quantifier - for example [ab]{6,} - was not handled - correctly by pce_dfa_exec(). It would match only one character. - -18. A valid (though odd) pattern that looked like a POSIX character - class but used an invalid character after [ (for example [[,abc,]]) caused - pcre_compile() to give the error "Failed: internal error: code overflow" or - in some cases to crash with a glibc free() error. This could even happen if - the pattern terminated after [[ but there just happened to be a sequence of - letters, a binary zero, and a closing ] in the memory that followed. - -19. Perl's treatment of octal escapes in the range \400 to \777 has changed - over the years. Originally (before any Unicode support), just the bottom 8 - bits were taken. Thus, for example, \500 really meant \100. Nowadays the - output from "man perlunicode" includes this: - - The regular expression compiler produces polymorphic opcodes. That - is, the pattern adapts to the data and automatically switches to - the Unicode character scheme when presented with Unicode data--or - instead uses a traditional byte scheme when presented with byte - data. - - Sadly, a wide octal escape does not cause a switch, and in a string with - no other multibyte characters, these octal escapes are treated as before. - Thus, in Perl, the pattern /\500/ actually matches \100 but the pattern - /\500|\x{1ff}/ matches \500 or \777 because the whole thing is treated as a - Unicode string. - - I have not perpetrated such confusion in PCRE. Up till now, it took just - the bottom 8 bits, as in old Perl. I have now made octal escapes with - values greater than \377 illegal in non-UTF-8 mode. In UTF-8 mode they - translate to the appropriate multibyte character. - -29. Applied some refactoring to reduce the number of warnings from Microsoft - and Borland compilers. This has included removing the fudge introduced - seven years ago for the OS/2 compiler (see 2.02/2 below) because it caused - a warning about an unused variable. - -21. PCRE has not included VT (character 0x0b) in the set of whitespace - characters since release 4.0, because Perl (from release 5.004) does not. - [Or at least, is documented not to: some releases seem to be in conflict - with the documentation.] However, when a pattern was studied with - pcre_study() and all its branches started with \s, PCRE still included VT - as a possible starting character. Of course, this did no harm; it just - caused an unnecessary match attempt. - -22. Removed a now-redundant internal flag bit that recorded the fact that case - dependency changed within the pattern. This was once needed for "required - byte" processing, but is no longer used. This recovers a now-scarce options - bit. Also moved the least significant internal flag bit to the most- - significant bit of the word, which was not previously used (hangover from - the days when it was an int rather than a uint) to free up another bit for - the future. - -23. Added support for CRLF line endings as well as CR and LF. As well as the - default being selectable at build time, it can now be changed at runtime - via the PCRE_NEWLINE_xxx flags. There are now options for pcregrep to - specify that it is scanning data with non-default line endings. - -24. Changed the definition of CXXLINK to make it agree with the definition of - LINK in the Makefile, by replacing LDFLAGS to CXXFLAGS. - -25. Applied Ian Taylor's patches to avoid using another stack frame for tail - recursions. This makes a big different to stack usage for some patterns. - -26. If a subpattern containing a named recursion or subroutine reference such - as (?P>B) was quantified, for example (xxx(?P>B)){3}, the calculation of - the space required for the compiled pattern went wrong and gave too small a - value. Depending on the environment, this could lead to "Failed: internal - error: code overflow at offset 49" or "glibc detected double free or - corruption" errors. - -27. Applied patches from Google (a) to support the new newline modes and (b) to - advance over multibyte UTF-8 characters in GlobalReplace. - -28. Change free() to pcre_free() in pcredemo.c. Apparently this makes a - difference for some implementation of PCRE in some Windows version. - -29. Added some extra testing facilities to pcretest: - - \q<number> in a data line sets the "match limit" value - \Q<number> in a data line sets the "match recursion limt" value - -S <number> sets the stack size, where <number> is in megabytes - - The -S option isn't available for Windows. - - -Version 6.6 06-Feb-06 ---------------------- - - 1. Change 16(a) for 6.5 broke things, because PCRE_DATA_SCOPE was not defined - in pcreposix.h. I have copied the definition from pcre.h. - - 2. Change 25 for 6.5 broke compilation in a build directory out-of-tree - because pcre.h is no longer a built file. - - 3. Added Jeff Friedl's additional debugging patches to pcregrep. These are - not normally included in the compiled code. - - -Version 6.5 01-Feb-06 ---------------------- - - 1. When using the partial match feature with pcre_dfa_exec(), it was not - anchoring the second and subsequent partial matches at the new starting - point. This could lead to incorrect results. For example, with the pattern - /1234/, partially matching against "123" and then "a4" gave a match. - - 2. Changes to pcregrep: - - (a) All non-match returns from pcre_exec() were being treated as failures - to match the line. Now, unless the error is PCRE_ERROR_NOMATCH, an - error message is output. Some extra information is given for the - PCRE_ERROR_MATCHLIMIT and PCRE_ERROR_RECURSIONLIMIT errors, which are - probably the only errors that are likely to be caused by users (by - specifying a regex that has nested indefinite repeats, for instance). - If there are more than 20 of these errors, pcregrep is abandoned. - - (b) A binary zero was treated as data while matching, but terminated the - output line if it was written out. This has been fixed: binary zeroes - are now no different to any other data bytes. - - (c) Whichever of the LC_ALL or LC_CTYPE environment variables is set is - used to set a locale for matching. The --locale=xxxx long option has - been added (no short equivalent) to specify a locale explicitly on the - pcregrep command, overriding the environment variables. - - (d) When -B was used with -n, some line numbers in the output were one less - than they should have been. - - (e) Added the -o (--only-matching) option. - - (f) If -A or -C was used with -c (count only), some lines of context were - accidentally printed for the final match. - - (g) Added the -H (--with-filename) option. - - (h) The combination of options -rh failed to suppress file names for files - that were found from directory arguments. - - (i) Added the -D (--devices) and -d (--directories) options. - - (j) Added the -F (--fixed-strings) option. - - (k) Allow "-" to be used as a file name for -f as well as for a data file. - - (l) Added the --colo(u)r option. - - (m) Added Jeffrey Friedl's -S testing option, but within #ifdefs so that it - is not present by default. - - 3. A nasty bug was discovered in the handling of recursive patterns, that is, - items such as (?R) or (?1), when the recursion could match a number of - alternatives. If it matched one of the alternatives, but subsequently, - outside the recursion, there was a failure, the code tried to back up into - the recursion. However, because of the way PCRE is implemented, this is not - possible, and the result was an incorrect result from the match. - - In order to prevent this happening, the specification of recursion has - been changed so that all such subpatterns are automatically treated as - atomic groups. Thus, for example, (?R) is treated as if it were (?>(?R)). - - 4. I had overlooked the fact that, in some locales, there are characters for - which isalpha() is true but neither isupper() nor islower() are true. In - the fr_FR locale, for instance, the \xAA and \xBA characters (ordmasculine - and ordfeminine) are like this. This affected the treatment of \w and \W - when they appeared in character classes, but not when they appeared outside - a character class. The bit map for "word" characters is now created - separately from the results of isalnum() instead of just taking it from the - upper, lower, and digit maps. (Plus the underscore character, of course.) - - 5. The above bug also affected the handling of POSIX character classes such as - [[:alpha:]] and [[:alnum:]]. These do not have their own bit maps in PCRE's - permanent tables. Instead, the bit maps for such a class were previously - created as the appropriate unions of the upper, lower, and digit bitmaps. - Now they are created by subtraction from the [[:word:]] class, which has - its own bitmap. - - 6. The [[:blank:]] character class matches horizontal, but not vertical space. - It is created by subtracting the vertical space characters (\x09, \x0a, - \x0b, \x0c) from the [[:space:]] bitmap. Previously, however, the - subtraction was done in the overall bitmap for a character class, meaning - that a class such as [\x0c[:blank:]] was incorrect because \x0c would not - be recognized. This bug has been fixed. - - 7. Patches from the folks at Google: - - (a) pcrecpp.cc: "to handle a corner case that may or may not happen in - real life, but is still worth protecting against". - - (b) pcrecpp.cc: "corrects a bug when negative radixes are used with - regular expressions". - - (c) pcre_scanner.cc: avoid use of std::count() because not all systems - have it. - - (d) Split off pcrecpparg.h from pcrecpp.h and had the former built by - "configure" and the latter not, in order to fix a problem somebody had - with compiling the Arg class on HP-UX. - - (e) Improve the error-handling of the C++ wrapper a little bit. - - (f) New tests for checking recursion limiting. - - 8. The pcre_memmove() function, which is used only if the environment does not - have a standard memmove() function (and is therefore rarely compiled), - contained two bugs: (a) use of int instead of size_t, and (b) it was not - returning a result (though PCRE never actually uses the result). - - 9. In the POSIX regexec() interface, if nmatch is specified as a ridiculously - large number - greater than INT_MAX/(3*sizeof(int)) - REG_ESPACE is - returned instead of calling malloc() with an overflowing number that would - most likely cause subsequent chaos. - -10. The debugging option of pcretest was not showing the NO_AUTO_CAPTURE flag. - -11. The POSIX flag REG_NOSUB is now supported. When a pattern that was compiled - with this option is matched, the nmatch and pmatch options of regexec() are - ignored. - -12. Added REG_UTF8 to the POSIX interface. This is not defined by POSIX, but is - provided in case anyone wants to the the POSIX interface with UTF-8 - strings. - -13. Added CXXLDFLAGS to the Makefile parameters to provide settings only on the - C++ linking (needed for some HP-UX environments). - -14. Avoid compiler warnings in get_ucpname() when compiled without UCP support - (unused parameter) and in the pcre_printint() function (omitted "default" - switch label when the default is to do nothing). - -15. Added some code to make it possible, when PCRE is compiled as a C++ - library, to replace subject pointers for pcre_exec() with a smart pointer - class, thus making it possible to process discontinuous strings. - -16. The two macros PCRE_EXPORT and PCRE_DATA_SCOPE are confusing, and perform - much the same function. They were added by different people who were trying - to make PCRE easy to compile on non-Unix systems. It has been suggested - that PCRE_EXPORT be abolished now that there is more automatic apparatus - for compiling on Windows systems. I have therefore replaced it with - PCRE_DATA_SCOPE. This is set automatically for Windows; if not set it - defaults to "extern" for C or "extern C" for C++, which works fine on - Unix-like systems. It is now possible to override the value of PCRE_DATA_ - SCOPE with something explicit in config.h. In addition: - - (a) pcreposix.h still had just "extern" instead of either of these macros; - I have replaced it with PCRE_DATA_SCOPE. - - (b) Functions such as _pcre_xclass(), which are internal to the library, - but external in the C sense, all had PCRE_EXPORT in their definitions. - This is apparently wrong for the Windows case, so I have removed it. - (It makes no difference on Unix-like systems.) - -17. Added a new limit, MATCH_LIMIT_RECURSION, which limits the depth of nesting - of recursive calls to match(). This is different to MATCH_LIMIT because - that limits the total number of calls to match(), not all of which increase - the depth of recursion. Limiting the recursion depth limits the amount of - stack (or heap if NO_RECURSE is set) that is used. The default can be set - when PCRE is compiled, and changed at run time. A patch from Google adds - this functionality to the C++ interface. - -18. Changes to the handling of Unicode character properties: - - (a) Updated the table to Unicode 4.1.0. - - (b) Recognize characters that are not in the table as "Cn" (undefined). - - (c) I revised the way the table is implemented to a much improved format - which includes recognition of ranges. It now supports the ranges that - are defined in UnicodeData.txt, and it also amalgamates other - characters into ranges. This has reduced the number of entries in the - table from around 16,000 to around 3,000, thus reducing its size - considerably. I realized I did not need to use a tree structure after - all - a binary chop search is just as efficient. Having reduced the - number of entries, I extended their size from 6 bytes to 8 bytes to - allow for more data. - - (d) Added support for Unicode script names via properties such as \p{Han}. - -19. In UTF-8 mode, a backslash followed by a non-Ascii character was not - matching that character. - -20. When matching a repeated Unicode property with a minimum greater than zero, - (for example \pL{2,}), PCRE could look past the end of the subject if it - reached it while seeking the minimum number of characters. This could - happen only if some of the characters were more than one byte long, because - there is a check for at least the minimum number of bytes. - -21. Refactored the implementation of \p and \P so as to be more general, to - allow for more different types of property in future. This has changed the - compiled form incompatibly. Anybody with saved compiled patterns that use - \p or \P will have to recompile them. - -22. Added "Any" and "L&" to the supported property types. - -23. Recognize \x{...} as a code point specifier, even when not in UTF-8 mode, - but give a compile time error if the value is greater than 0xff. - -24. The man pages for pcrepartial, pcreprecompile, and pcre_compile2 were - accidentally not being installed or uninstalled. - -25. The pcre.h file was built from pcre.h.in, but the only changes that were - made were to insert the current release number. This seemed silly, because - it made things harder for people building PCRE on systems that don't run - "configure". I have turned pcre.h into a distributed file, no longer built - by "configure", with the version identification directly included. There is - no longer a pcre.h.in file. - - However, this change necessitated a change to the pcre-config script as - well. It is built from pcre-config.in, and one of the substitutions was the - release number. I have updated configure.ac so that ./configure now finds - the release number by grepping pcre.h. - -26. Added the ability to run the tests under valgrind. - - -Version 6.4 05-Sep-05 ---------------------- - - 1. Change 6.0/10/(l) to pcregrep introduced a bug that caused separator lines - "--" to be printed when multiple files were scanned, even when none of the - -A, -B, or -C options were used. This is not compatible with Gnu grep, so I - consider it to be a bug, and have restored the previous behaviour. - - 2. A couple of code tidies to get rid of compiler warnings. - - 3. The pcretest program used to cheat by referring to symbols in the library - whose names begin with _pcre_. These are internal symbols that are not - really supposed to be visible externally, and in some environments it is - possible to suppress them. The cheating is now confined to including - certain files from the library's source, which is a bit cleaner. - - 4. Renamed pcre.in as pcre.h.in to go with pcrecpp.h.in; it also makes the - file's purpose clearer. - - 5. Reorganized pcre_ucp_findchar(). - - -Version 6.3 15-Aug-05 ---------------------- - - 1. The file libpcre.pc.in did not have general read permission in the tarball. - - 2. There were some problems when building without C++ support: - - (a) If C++ support was not built, "make install" and "make test" still - tried to test it. - - (b) There were problems when the value of CXX was explicitly set. Some - changes have been made to try to fix these, and ... - - (c) --disable-cpp can now be used to explicitly disable C++ support. - - (d) The use of @CPP_OBJ@ directly caused a blank line preceded by a - backslash in a target when C++ was disabled. This confuses some - versions of "make", apparently. Using an intermediate variable solves - this. (Same for CPP_LOBJ.) - - 3. $(LINK_FOR_BUILD) now includes $(CFLAGS_FOR_BUILD) and $(LINK) - (non-Windows) now includes $(CFLAGS) because these flags are sometimes - necessary on certain architectures. - - 4. Added a setting of -export-symbols-regex to the link command to remove - those symbols that are exported in the C sense, but actually are local - within the library, and not documented. Their names all begin with - "_pcre_". This is not a perfect job, because (a) we have to except some - symbols that pcretest ("illegally") uses, and (b) the facility isn't always - available (and never for static libraries). I have made a note to try to - find a way round (a) in the future. - - -Version 6.2 01-Aug-05 ---------------------- - - 1. There was no test for integer overflow of quantifier values. A construction - such as {1111111111111111} would give undefined results. What is worse, if - a minimum quantifier for a parenthesized subpattern overflowed and became - negative, the calculation of the memory size went wrong. This could have - led to memory overwriting. - - 2. Building PCRE using VPATH was broken. Hopefully it is now fixed. - - 3. Added "b" to the 2nd argument of fopen() in dftables.c, for non-Unix-like - operating environments where this matters. - - 4. Applied Giuseppe Maxia's patch to add additional features for controlling - PCRE options from within the C++ wrapper. - - 5. Named capturing subpatterns were not being correctly counted when a pattern - was compiled. This caused two problems: (a) If there were more than 100 - such subpatterns, the calculation of the memory needed for the whole - compiled pattern went wrong, leading to an overflow error. (b) Numerical - back references of the form \12, where the number was greater than 9, were - not recognized as back references, even though there were sufficient - previous subpatterns. - - 6. Two minor patches to pcrecpp.cc in order to allow it to compile on older - versions of gcc, e.g. 2.95.4. - - -Version 6.1 21-Jun-05 ---------------------- - - 1. There was one reference to the variable "posix" in pcretest.c that was not - surrounded by "#if !defined NOPOSIX". - - 2. Make it possible to compile pcretest without DFA support, UTF8 support, or - the cross-check on the old pcre_info() function, for the benefit of the - cut-down version of PCRE that is currently imported into Exim. - - 3. A (silly) pattern starting with (?i)(?-i) caused an internal space - allocation error. I've done the easy fix, which wastes 2 bytes for sensible - patterns that start (?i) but I don't think that matters. The use of (?i) is - just an example; this all applies to the other options as well. - - 4. Since libtool seems to echo the compile commands it is issuing, the output - from "make" can be reduced a bit by putting "@" in front of each libtool - compile command. - - 5. Patch from the folks at Google for configure.in to be a bit more thorough - in checking for a suitable C++ installation before trying to compile the - C++ stuff. This should fix a reported problem when a compiler was present, - but no suitable headers. - - 6. The man pages all had just "PCRE" as their title. I have changed them to - be the relevant file name. I have also arranged that these names are - retained in the file doc/pcre.txt, which is a concatenation in text format - of all the man pages except the little individual ones for each function. - - 7. The NON-UNIX-USE file had not been updated for the different set of source - files that come with release 6. I also added a few comments about the C++ - wrapper. - - -Version 6.0 07-Jun-05 ---------------------- - - 1. Some minor internal re-organization to help with my DFA experiments. - - 2. Some missing #ifdef SUPPORT_UCP conditionals in pcretest and printint that - didn't matter for the library itself when fully configured, but did matter - when compiling without UCP support, or within Exim, where the ucp files are - not imported. - - 3. Refactoring of the library code to split up the various functions into - different source modules. The addition of the new DFA matching code (see - below) to a single monolithic source would have made it really too - unwieldy, quite apart from causing all the code to be include in a - statically linked application, when only some functions are used. This is - relevant even without the DFA addition now that patterns can be compiled in - one application and matched in another. - - The downside of splitting up is that there have to be some external - functions and data tables that are used internally in different modules of - the library but which are not part of the API. These have all had their - names changed to start with "_pcre_" so that they are unlikely to clash - with other external names. - - 4. Added an alternate matching function, pcre_dfa_exec(), which matches using - a different (DFA) algorithm. Although it is slower than the original - function, it does have some advantages for certain types of matching - problem. - - 5. Upgrades to pcretest in order to test the features of pcre_dfa_exec(), - including restarting after a partial match. - - 6. A patch for pcregrep that defines INVALID_FILE_ATTRIBUTES if it is not - defined when compiling for Windows was sent to me. I have put it into the - code, though I have no means of testing or verifying it. - - 7. Added the pcre_refcount() auxiliary function. - - 8. Added the PCRE_FIRSTLINE option. This constrains an unanchored pattern to - match before or at the first newline in the subject string. In pcretest, - the /f option on a pattern can be used to set this. - - 9. A repeated \w when used in UTF-8 mode with characters greater than 256 - would behave wrongly. This has been present in PCRE since release 4.0. - -10. A number of changes to the pcregrep command: - - (a) Refactored how -x works; insert ^(...)$ instead of setting - PCRE_ANCHORED and checking the length, in preparation for adding - something similar for -w. - - (b) Added the -w (match as a word) option. - - (c) Refactored the way lines are read and buffered so as to have more - than one at a time available. - - (d) Implemented a pcregrep test script. - - (e) Added the -M (multiline match) option. This allows patterns to match - over several lines of the subject. The buffering ensures that at least - 8K, or the rest of the document (whichever is the shorter) is available - for matching (and similarly the previous 8K for lookbehind assertions). - - (f) Changed the --help output so that it now says - - -w, --word-regex(p) - - instead of two lines, one with "regex" and the other with "regexp" - because that confused at least one person since the short forms are the - same. (This required a bit of code, as the output is generated - automatically from a table. It wasn't just a text change.) - - (g) -- can be used to terminate pcregrep options if the next thing isn't an - option but starts with a hyphen. Could be a pattern or a path name - starting with a hyphen, for instance. - - (h) "-" can be given as a file name to represent stdin. - - (i) When file names are being printed, "(standard input)" is used for - the standard input, for compatibility with GNU grep. Previously - "<stdin>" was used. - - (j) The option --label=xxx can be used to supply a name to be used for - stdin when file names are being printed. There is no short form. - - (k) Re-factored the options decoding logic because we are going to add - two more options that take data. Such options can now be given in four - different ways, e.g. "-fname", "-f name", "--file=name", "--file name". - - (l) Added the -A, -B, and -C options for requesting that lines of context - around matches be printed. - - (m) Added the -L option to print the names of files that do not contain - any matching lines, that is, the complement of -l. - - (n) The return code is 2 if any file cannot be opened, but pcregrep does - continue to scan other files. - - (o) The -s option was incorrectly implemented. For compatibility with other - greps, it now suppresses the error message for a non-existent or non- - accessible file (but not the return code). There is a new option called - -q that suppresses the output of matching lines, which was what -s was - previously doing. - - (p) Added --include and --exclude options to specify files for inclusion - and exclusion when recursing. - -11. The Makefile was not using the Autoconf-supported LDFLAGS macro properly. - Hopefully, it now does. - -12. Missing cast in pcre_study(). - -13. Added an "uninstall" target to the makefile. - -14. Replaced "extern" in the function prototypes in Makefile.in with - "PCRE_DATA_SCOPE", which defaults to 'extern' or 'extern "C"' in the Unix - world, but is set differently for Windows. - -15. Added a second compiling function called pcre_compile2(). The only - difference is that it has an extra argument, which is a pointer to an - integer error code. When there is a compile-time failure, this is set - non-zero, in addition to the error test pointer being set to point to an - error message. The new argument may be NULL if no error number is required - (but then you may as well call pcre_compile(), which is now just a - wrapper). This facility is provided because some applications need a - numeric error indication, but it has also enabled me to tidy up the way - compile-time errors are handled in the POSIX wrapper. - -16. Added VPATH=.libs to the makefile; this should help when building with one - prefix path and installing with another. (Or so I'm told by someone who - knows more about this stuff than I do.) - -17. Added a new option, REG_DOTALL, to the POSIX function regcomp(). This - passes PCRE_DOTALL to the pcre_compile() function, making the "." character - match everything, including newlines. This is not POSIX-compatible, but - somebody wanted the feature. From pcretest it can be activated by using - both the P and the s flags. - -18. AC_PROG_LIBTOOL appeared twice in Makefile.in. Removed one. - -19. libpcre.pc was being incorrectly installed as executable. - -20. A couple of places in pcretest check for end-of-line by looking for '\n'; - it now also looks for '\r' so that it will work unmodified on Windows. - -21. Added Google's contributed C++ wrapper to the distribution. - -22. Added some untidy missing memory free() calls in pcretest, to keep - Electric Fence happy when testing. - - - -Version 5.0 13-Sep-04 ---------------------- - - 1. Internal change: literal characters are no longer packed up into items - containing multiple characters in a single byte-string. Each character - is now matched using a separate opcode. However, there may be more than one - byte in the character in UTF-8 mode. - - 2. The pcre_callout_block structure has two new fields: pattern_position and - next_item_length. These contain the offset in the pattern to the next match - item, and its length, respectively. - - 3. The PCRE_AUTO_CALLOUT option for pcre_compile() requests the automatic - insertion of callouts before each pattern item. Added the /C option to - pcretest to make use of this. - - 4. On the advice of a Windows user, the lines - - #if defined(_WIN32) || defined(WIN32) - _setmode( _fileno( stdout ), 0x8000 ); - #endif /* defined(_WIN32) || defined(WIN32) */ - - have been added to the source of pcretest. This apparently does useful - magic in relation to line terminators. - - 5. Changed "r" and "w" in the calls to fopen() in pcretest to "rb" and "wb" - for the benefit of those environments where the "b" makes a difference. - - 6. The icc compiler has the same options as gcc, but "configure" doesn't seem - to know about it. I have put a hack into configure.in that adds in code - to set GCC=yes if CC=icc. This seems to end up at a point in the - generated configure script that is early enough to affect the setting of - compiler options, which is what is needed, but I have no means of testing - whether it really works. (The user who reported this had patched the - generated configure script, which of course I cannot do.) - - LATER: After change 22 below (new libtool files), the configure script - seems to know about icc (and also ecc). Therefore, I have commented out - this hack in configure.in. - - 7. Added support for pkg-config (2 patches were sent in). - - 8. Negated POSIX character classes that used a combination of internal tables - were completely broken. These were [[:^alpha:]], [[:^alnum:]], and - [[:^ascii]]. Typically, they would match almost any characters. The other - POSIX classes were not broken in this way. - - 9. Matching the pattern "\b.*?" against "ab cd", starting at offset 1, failed - to find the match, as PCRE was deluded into thinking that the match had to - start at the start point or following a newline. The same bug applied to - patterns with negative forward assertions or any backward assertions - preceding ".*" at the start, unless the pattern required a fixed first - character. This was a failing pattern: "(?!.bcd).*". The bug is now fixed. - -10. In UTF-8 mode, when moving forwards in the subject after a failed match - starting at the last subject character, bytes beyond the end of the subject - string were read. - -11. Renamed the variable "class" as "classbits" to make life easier for C++ - users. (Previously there was a macro definition, but it apparently wasn't - enough.) - -12. Added the new field "tables" to the extra data so that tables can be passed - in at exec time, or the internal tables can be re-selected. This allows - a compiled regex to be saved and re-used at a later time by a different - program that might have everything at different addresses. - -13. Modified the pcre-config script so that, when run on Solaris, it shows a - -R library as well as a -L library. - -14. The debugging options of pcretest (-d on the command line or D on a - pattern) showed incorrect output for anything following an extended class - that contained multibyte characters and which was followed by a quantifier. - -15. Added optional support for general category Unicode character properties - via the \p, \P, and \X escapes. Unicode property support implies UTF-8 - support. It adds about 90K to the size of the library. The meanings of the - inbuilt class escapes such as \d and \s have NOT been changed. - -16. Updated pcredemo.c to include calls to free() to release the memory for the - compiled pattern. - -17. The generated file chartables.c was being created in the source directory - instead of in the building directory. This caused the build to fail if the - source directory was different from the building directory, and was - read-only. - -18. Added some sample Win commands from Mark Tetrode into the NON-UNIX-USE - file. No doubt somebody will tell me if they don't make sense... Also added - Dan Mooney's comments about building on OpenVMS. - -19. Added support for partial matching via the PCRE_PARTIAL option for - pcre_exec() and the \P data escape in pcretest. - -20. Extended pcretest with 3 new pattern features: - - (i) A pattern option of the form ">rest-of-line" causes pcretest to - write the compiled pattern to the file whose name is "rest-of-line". - This is a straight binary dump of the data, with the saved pointer to - the character tables forced to be NULL. The study data, if any, is - written too. After writing, pcretest reads a new pattern. - - (ii) If, instead of a pattern, "<rest-of-line" is given, pcretest reads a - compiled pattern from the given file. There must not be any - occurrences of "<" in the file name (pretty unlikely); if there are, - pcretest will instead treat the initial "<" as a pattern delimiter. - After reading in the pattern, pcretest goes on to read data lines as - usual. - - (iii) The F pattern option causes pcretest to flip the bytes in the 32-bit - and 16-bit fields in a compiled pattern, to simulate a pattern that - was compiled on a host of opposite endianness. - -21. The pcre-exec() function can now cope with patterns that were compiled on - hosts of opposite endianness, with this restriction: - - As for any compiled expression that is saved and used later, the tables - pointer field cannot be preserved; the extra_data field in the arguments - to pcre_exec() should be used to pass in a tables address if a value - other than the default internal tables were used at compile time. - -22. Calling pcre_exec() with a negative value of the "ovecsize" parameter is - now diagnosed as an error. Previously, most of the time, a negative number - would have been treated as zero, but if in addition "ovector" was passed as - NULL, a crash could occur. - -23. Updated the files ltmain.sh, config.sub, config.guess, and aclocal.m4 with - new versions from the libtool 1.5 distribution (the last one is a copy of - a file called libtool.m4). This seems to have fixed the need to patch - "configure" to support Darwin 1.3 (which I used to do). However, I still - had to patch ltmain.sh to ensure that ${SED} is set (it isn't on my - workstation). - -24. Changed the PCRE licence to be the more standard "BSD" licence. - - -Version 4.5 01-Dec-03 ---------------------- - - 1. There has been some re-arrangement of the code for the match() function so - that it can be compiled in a version that does not call itself recursively. - Instead, it keeps those local variables that need separate instances for - each "recursion" in a frame on the heap, and gets/frees frames whenever it - needs to "recurse". Keeping track of where control must go is done by means - of setjmp/longjmp. The whole thing is implemented by a set of macros that - hide most of the details from the main code, and operates only if - NO_RECURSE is defined while compiling pcre.c. If PCRE is built using the - "configure" mechanism, "--disable-stack-for-recursion" turns on this way of - operating. - - To make it easier for callers to provide specially tailored get/free - functions for this usage, two new functions, pcre_stack_malloc, and - pcre_stack_free, are used. They are always called in strict stacking order, - and the size of block requested is always the same. - - The PCRE_CONFIG_STACKRECURSE info parameter can be used to find out whether - PCRE has been compiled to use the stack or the heap for recursion. The - -C option of pcretest uses this to show which version is compiled. - - A new data escape \S, is added to pcretest; it causes the amounts of store - obtained and freed by both kinds of malloc/free at match time to be added - to the output. - - 2. Changed the locale test to use "fr_FR" instead of "fr" because that's - what's available on my current Linux desktop machine. - - 3. When matching a UTF-8 string, the test for a valid string at the start has - been extended. If start_offset is not zero, PCRE now checks that it points - to a byte that is the start of a UTF-8 character. If not, it returns - PCRE_ERROR_BADUTF8_OFFSET (-11). Note: the whole string is still checked; - this is necessary because there may be backward assertions in the pattern. - When matching the same subject several times, it may save resources to use - PCRE_NO_UTF8_CHECK on all but the first call if the string is long. - - 4. The code for checking the validity of UTF-8 strings has been tightened so - that it rejects (a) strings containing 0xfe or 0xff bytes and (b) strings - containing "overlong sequences". - - 5. Fixed a bug (appearing twice) that I could not find any way of exploiting! - I had written "if ((digitab[*p++] && chtab_digit) == 0)" where the "&&" - should have been "&", but it just so happened that all the cases this let - through by mistake were picked up later in the function. - - 6. I had used a variable called "isblank" - this is a C99 function, causing - some compilers to warn. To avoid this, I renamed it (as "blankclass"). - - 7. Cosmetic: (a) only output another newline at the end of pcretest if it is - prompting; (b) run "./pcretest /dev/null" at the start of the test script - so the version is shown; (c) stop "make test" echoing "./RunTest". - - 8. Added patches from David Burgess to enable PCRE to run on EBCDIC systems. - - 9. The prototype for memmove() for systems that don't have it was using - size_t, but the inclusion of the header that defines size_t was later. I've - moved the #includes for the C headers earlier to avoid this. - -10. Added some adjustments to the code to make it easier to compiler on certain - special systems: - - (a) Some "const" qualifiers were missing. - (b) Added the macro EXPORT before all exported functions; by default this - is defined to be empty. - (c) Changed the dftables auxiliary program (that builds chartables.c) so - that it reads its output file name as an argument instead of writing - to the standard output and assuming this can be redirected. - -11. In UTF-8 mode, if a recursive reference (e.g. (?1)) followed a character - class containing characters with values greater than 255, PCRE compilation - went into a loop. - -12. A recursive reference to a subpattern that was within another subpattern - that had a minimum quantifier of zero caused PCRE to crash. For example, - (x(y(?2))z)? provoked this bug with a subject that got as far as the - recursion. If the recursively-called subpattern itself had a zero repeat, - that was OK. - -13. In pcretest, the buffer for reading a data line was set at 30K, but the - buffer into which it was copied (for escape processing) was still set at - 1024, so long lines caused crashes. - -14. A pattern such as /[ab]{1,3}+/ failed to compile, giving the error - "internal error: code overflow...". This applied to any character class - that was followed by a possessive quantifier. - -15. Modified the Makefile to add libpcre.la as a prerequisite for - libpcreposix.la because I was told this is needed for a parallel build to - work. - -16. If a pattern that contained .* following optional items at the start was - studied, the wrong optimizing data was generated, leading to matching - errors. For example, studying /[ab]*.*c/ concluded, erroneously, that any - matching string must start with a or b or c. The correct conclusion for - this pattern is that a match can start with any character. - - -Version 4.4 13-Aug-03 ---------------------- - - 1. In UTF-8 mode, a character class containing characters with values between - 127 and 255 was not handled correctly if the compiled pattern was studied. - In fixing this, I have also improved the studying algorithm for such - classes (slightly). - - 2. Three internal functions had redundant arguments passed to them. Removal - might give a very teeny performance improvement. - - 3. Documentation bug: the value of the capture_top field in a callout is *one - more than* the number of the hightest numbered captured substring. - - 4. The Makefile linked pcretest and pcregrep with -lpcre, which could result - in incorrectly linking with a previously installed version. They now link - explicitly with libpcre.la. - - 5. configure.in no longer needs to recognize Cygwin specially. - - 6. A problem in pcre.in for Windows platforms is fixed. - - 7. If a pattern was successfully studied, and the -d (or /D) flag was given to - pcretest, it used to include the size of the study block as part of its - output. Unfortunately, the structure contains a field that has a different - size on different hardware architectures. This meant that the tests that - showed this size failed. As the block is currently always of a fixed size, - this information isn't actually particularly useful in pcretest output, so - I have just removed it. - - 8. Three pre-processor statements accidentally did not start in column 1. - Sadly, there are *still* compilers around that complain, even though - standard C has not required this for well over a decade. Sigh. - - 9. In pcretest, the code for checking callouts passed small integers in the - callout_data field, which is a void * field. However, some picky compilers - complained about the casts involved for this on 64-bit systems. Now - pcretest passes the address of the small integer instead, which should get - rid of the warnings. - -10. By default, when in UTF-8 mode, PCRE now checks for valid UTF-8 strings at - both compile and run time, and gives an error if an invalid UTF-8 sequence - is found. There is a option for disabling this check in cases where the - string is known to be correct and/or the maximum performance is wanted. - -11. In response to a bug report, I changed one line in Makefile.in from - - -Wl,--out-implib,.libs/lib@WIN_PREFIX@pcreposix.dll.a \ - to - -Wl,--out-implib,.libs/@WIN_PREFIX@libpcreposix.dll.a \ - - to look similar to other lines, but I have no way of telling whether this - is the right thing to do, as I do not use Windows. No doubt I'll get told - if it's wrong... - - -Version 4.3 21-May-03 ---------------------- - -1. Two instances of @WIN_PREFIX@ omitted from the Windows targets in the - Makefile. - -2. Some refactoring to improve the quality of the code: - - (i) The utf8_table... variables are now declared "const". - - (ii) The code for \cx, which used the "case flipping" table to upper case - lower case letters, now just substracts 32. This is ASCII-specific, - but the whole concept of \cx is ASCII-specific, so it seems - reasonable. - - (iii) PCRE was using its character types table to recognize decimal and - hexadecimal digits in the pattern. This is silly, because it handles - only 0-9, a-f, and A-F, but the character types table is locale- - specific, which means strange things might happen. A private - table is now used for this - though it costs 256 bytes, a table is - much faster than multiple explicit tests. Of course, the standard - character types table is still used for matching digits in subject - strings against \d. - - (iv) Strictly, the identifier ESC_t is reserved by POSIX (all identifiers - ending in _t are). So I've renamed it as ESC_tee. - -3. The first argument for regexec() in the POSIX wrapper should have been - defined as "const". - -4. Changed pcretest to use malloc() for its buffers so that they can be - Electric Fenced for debugging. - -5. There were several places in the code where, in UTF-8 mode, PCRE would try - to read one or more bytes before the start of the subject string. Often this - had no effect on PCRE's behaviour, but in some circumstances it could - provoke a segmentation fault. - -6. A lookbehind at the start of a pattern in UTF-8 mode could also cause PCRE - to try to read one or more bytes before the start of the subject string. - -7. A lookbehind in a pattern matched in non-UTF-8 mode on a PCRE compiled with - UTF-8 support could misbehave in various ways if the subject string - contained bytes with the 0x80 bit set and the 0x40 bit unset in a lookbehind - area. (PCRE was not checking for the UTF-8 mode flag, and trying to move - back over UTF-8 characters.) - - -Version 4.2 14-Apr-03 ---------------------- - -1. Typo "#if SUPPORT_UTF8" instead of "#ifdef SUPPORT_UTF8" fixed. - -2. Changes to the building process, supplied by Ronald Landheer-Cieslak - [ON_WINDOWS]: new variable, "#" on non-Windows platforms - [NOT_ON_WINDOWS]: new variable, "#" on Windows platforms - [WIN_PREFIX]: new variable, "cyg" for Cygwin - * Makefile.in: use autoconf substitution for OBJEXT, EXEEXT, BUILD_OBJEXT - and BUILD_EXEEXT - Note: automatic setting of the BUILD variables is not yet working - set CPPFLAGS and BUILD_CPPFLAGS (but don't use yet) - should be used at - compile-time but not at link-time - [LINK]: use for linking executables only - make different versions for Windows and non-Windows - [LINKLIB]: new variable, copy of UNIX-style LINK, used for linking - libraries - [LINK_FOR_BUILD]: new variable - [OBJEXT]: use throughout - [EXEEXT]: use throughout - <winshared>: new target - <wininstall>: new target - <dftables.o>: use native compiler - <dftables>: use native linker - <install>: handle Windows platform correctly - <clean>: ditto - <check>: ditto - copy DLL to top builddir before testing - - As part of these changes, -no-undefined was removed again. This was reported - to give trouble on HP-UX 11.0, so getting rid of it seems like a good idea - in any case. - -3. Some tidies to get rid of compiler warnings: - - . In the match_data structure, match_limit was an unsigned long int, whereas - match_call_count was an int. I've made them both unsigned long ints. - - . In pcretest the fact that a const uschar * doesn't automatically cast to - a void * provoked a warning. - - . Turning on some more compiler warnings threw up some "shadow" variables - and a few more missing casts. - -4. If PCRE was complied with UTF-8 support, but called without the PCRE_UTF8 - option, a class that contained a single character with a value between 128 - and 255 (e.g. /[\xFF]/) caused PCRE to crash. - -5. If PCRE was compiled with UTF-8 support, but called without the PCRE_UTF8 - option, a class that contained several characters, but with at least one - whose value was between 128 and 255 caused PCRE to crash. - - -Version 4.1 12-Mar-03 ---------------------- - -1. Compiling with gcc -pedantic found a couple of places where casts were -needed, and a string in dftables.c that was longer than standard compilers are -required to support. - -2. Compiling with Sun's compiler found a few more places where the code could -be tidied up in order to avoid warnings. - -3. The variables for cross-compiling were called HOST_CC and HOST_CFLAGS; the -first of these names is deprecated in the latest Autoconf in favour of the name -CC_FOR_BUILD, because "host" is typically used to mean the system on which the -compiled code will be run. I can't find a reference for HOST_CFLAGS, but by -analogy I have changed it to CFLAGS_FOR_BUILD. - -4. Added -no-undefined to the linking command in the Makefile, because this is -apparently helpful for Windows. To make it work, also added "-L. -lpcre" to the -linking step for the pcreposix library. - -5. PCRE was failing to diagnose the case of two named groups with the same -name. - -6. A problem with one of PCRE's optimizations was discovered. PCRE remembers a -literal character that is needed in the subject for a match, and scans along to -ensure that it is present before embarking on the full matching process. This -saves time in cases of nested unlimited repeats that are never going to match. -Problem: the scan can take a lot of time if the subject is very long (e.g. -megabytes), thus penalizing straightforward matches. It is now done only if the -amount of subject to be scanned is less than 1000 bytes. - -7. A lesser problem with the same optimization is that it was recording the -first character of an anchored pattern as "needed", thus provoking a search -right along the subject, even when the first match of the pattern was going to -fail. The "needed" character is now not set for anchored patterns, unless it -follows something in the pattern that is of non-fixed length. Thus, it still -fulfils its original purpose of finding quick non-matches in cases of nested -unlimited repeats, but isn't used for simple anchored patterns such as /^abc/. - - -Version 4.0 17-Feb-03 ---------------------- - -1. If a comment in an extended regex that started immediately after a meta-item -extended to the end of string, PCRE compiled incorrect data. This could lead to -all kinds of weird effects. Example: /#/ was bad; /()#/ was bad; /a#/ was not. - -2. Moved to autoconf 2.53 and libtool 1.4.2. - -3. Perl 5.8 no longer needs "use utf8" for doing UTF-8 things. Consequently, -the special perltest8 script is no longer needed - all the tests can be run -from a single perltest script. - -4. From 5.004, Perl has not included the VT character (0x0b) in the set defined -by \s. It has now been removed in PCRE. This means it isn't recognized as -whitespace in /x regexes too, which is the same as Perl. Note that the POSIX -class [:space:] *does* include VT, thereby creating a mess. - -5. Added the class [:blank:] (a GNU extension from Perl 5.8) to match only -space and tab. - -6. Perl 5.005 was a long time ago. It's time to amalgamate the tests that use -its new features into the main test script, reducing the number of scripts. - -7. Perl 5.8 has changed the meaning of patterns like /a(?i)b/. Earlier versions -were backward compatible, and made the (?i) apply to the whole pattern, as if -/i were given. Now it behaves more logically, and applies the option setting -only to what follows. PCRE has been changed to follow suit. However, if it -finds options settings right at the start of the pattern, it extracts them into -the global options, as before. Thus, they show up in the info data. - -8. Added support for the \Q...\E escape sequence. Characters in between are -treated as literals. This is slightly different from Perl in that $ and @ are -also handled as literals inside the quotes. In Perl, they will cause variable -interpolation. Note the following examples: - - Pattern PCRE matches Perl matches - - \Qabc$xyz\E abc$xyz abc followed by the contents of $xyz - \Qabc\$xyz\E abc\$xyz abc\$xyz - \Qabc\E\$\Qxyz\E abc$xyz abc$xyz - -For compatibility with Perl, \Q...\E sequences are recognized inside character -classes as well as outside them. - -9. Re-organized 3 code statements in pcretest to avoid "overflow in -floating-point constant arithmetic" warnings from a Microsoft compiler. Added a -(size_t) cast to one statement in pcretest and one in pcreposix to avoid -signed/unsigned warnings. - -10. SunOS4 doesn't have strtoul(). This was used only for unpicking the -o -option for pcretest, so I've replaced it by a simple function that does just -that job. - -11. pcregrep was ending with code 0 instead of 2 for the commands "pcregrep" or -"pcregrep -". - -12. Added "possessive quantifiers" ?+, *+, ++, and {,}+ which come from Sun's -Java package. This provides some syntactic sugar for simple cases of what my -documentation calls "once-only subpatterns". A pattern such as x*+ is the same -as (?>x*). In other words, if what is inside (?>...) is just a single repeated -item, you can use this simplified notation. Note that only makes sense with -greedy quantifiers. Consequently, the use of the possessive quantifier forces -greediness, whatever the setting of the PCRE_UNGREEDY option. - -13. A change of greediness default within a pattern was not taking effect at -the current level for patterns like /(b+(?U)a+)/. It did apply to parenthesized -subpatterns that followed. Patterns like /b+(?U)a+/ worked because the option -was abstracted outside. - -14. PCRE now supports the \G assertion. It is true when the current matching -position is at the start point of the match. This differs from \A when the -starting offset is non-zero. Used with the /g option of pcretest (or similar -code), it works in the same way as it does for Perl's /g option. If all -alternatives of a regex begin with \G, the expression is anchored to the start -match position, and the "anchored" flag is set in the compiled expression. - -15. Some bugs concerning the handling of certain option changes within patterns -have been fixed. These applied to options other than (?ims). For example, -"a(?x: b c )d" did not match "XabcdY" but did match "Xa b c dY". It should have -been the other way round. Some of this was related to change 7 above. - -16. PCRE now gives errors for /[.x.]/ and /[=x=]/ as unsupported POSIX -features, as Perl does. Previously, PCRE gave the warnings only for /[[.x.]]/ -and /[[=x=]]/. PCRE now also gives an error for /[:name:]/ because it supports -POSIX classes only within a class (e.g. /[[:alpha:]]/). - -17. Added support for Perl's \C escape. This matches one byte, even in UTF8 -mode. Unlike ".", it always matches newline, whatever the setting of -PCRE_DOTALL. However, PCRE does not permit \C to appear in lookbehind -assertions. Perl allows it, but it doesn't (in general) work because it can't -calculate the length of the lookbehind. At least, that's the case for Perl -5.8.0 - I've been told they are going to document that it doesn't work in -future. - -18. Added an error diagnosis for escapes that PCRE does not support: these are -\L, \l, \N, \P, \p, \U, \u, and \X. - -19. Although correctly diagnosing a missing ']' in a character class, PCRE was -reading past the end of the pattern in cases such as /[abcd/. - -20. PCRE was getting more memory than necessary for patterns with classes that -contained both POSIX named classes and other characters, e.g. /[[:space:]abc/. - -21. Added some code, conditional on #ifdef VPCOMPAT, to make life easier for -compiling PCRE for use with Virtual Pascal. - -22. Small fix to the Makefile to make it work properly if the build is done -outside the source tree. - -23. Added a new extension: a condition to go with recursion. If a conditional -subpattern starts with (?(R) the "true" branch is used if recursion has -happened, whereas the "false" branch is used only at the top level. - -24. When there was a very long string of literal characters (over 255 bytes -without UTF support, over 250 bytes with UTF support), the computation of how -much memory was required could be incorrect, leading to segfaults or other -strange effects. - -25. PCRE was incorrectly assuming anchoring (either to start of subject or to -start of line for a non-DOTALL pattern) when a pattern started with (.*) and -there was a subsequent back reference to those brackets. This meant that, for -example, /(.*)\d+\1/ failed to match "abc123bc". Unfortunately, it isn't -possible to check for precisely this case. All we can do is abandon the -optimization if .* occurs inside capturing brackets when there are any back -references whatsoever. (See below for a better fix that came later.) - -26. The handling of the optimization for finding the first character of a -non-anchored pattern, and for finding a character that is required later in the -match were failing in some cases. This didn't break the matching; it just -failed to optimize when it could. The way this is done has been re-implemented. - -27. Fixed typo in error message for invalid (?R item (it said "(?p"). - -28. Added a new feature that provides some of the functionality that Perl -provides with (?{...}). The facility is termed a "callout". The way it is done -in PCRE is for the caller to provide an optional function, by setting -pcre_callout to its entry point. Like pcre_malloc and pcre_free, this is a -global variable. By default it is unset, which disables all calling out. To get -the function called, the regex must include (?C) at appropriate points. This -is, in fact, equivalent to (?C0), and any number <= 255 may be given with (?C). -This provides a means of identifying different callout points. When PCRE -reaches such a point in the regex, if pcre_callout has been set, the external -function is called. It is provided with data in a structure called -pcre_callout_block, which is defined in pcre.h. If the function returns 0, -matching continues; if it returns a non-zero value, the match at the current -point fails. However, backtracking will occur if possible. [This was changed -later and other features added - see item 49 below.] - -29. pcretest is upgraded to test the callout functionality. It provides a -callout function that displays information. By default, it shows the start of -the match and the current position in the text. There are some new data escapes -to vary what happens: - - \C+ in addition, show current contents of captured substrings - \C- do not supply a callout function - \C!n return 1 when callout number n is reached - \C!n!m return 1 when callout number n is reached for the mth time - -30. If pcregrep was called with the -l option and just a single file name, it -output "<stdin>" if a match was found, instead of the file name. - -31. Improve the efficiency of the POSIX API to PCRE. If the number of capturing -slots is less than POSIX_MALLOC_THRESHOLD, use a block on the stack to pass to -pcre_exec(). This saves a malloc/free per call. The default value of -POSIX_MALLOC_THRESHOLD is 10; it can be changed by --with-posix-malloc-threshold -when configuring. - -32. The default maximum size of a compiled pattern is 64K. There have been a -few cases of people hitting this limit. The code now uses macros to handle the -storing of links as offsets within the compiled pattern. It defaults to 2-byte -links, but this can be changed to 3 or 4 bytes by --with-link-size when -configuring. Tests 2 and 5 work only with 2-byte links because they output -debugging information about compiled patterns. - -33. Internal code re-arrangements: - -(a) Moved the debugging function for printing out a compiled regex into - its own source file (printint.c) and used #include to pull it into - pcretest.c and, when DEBUG is defined, into pcre.c, instead of having two - separate copies. - -(b) Defined the list of op-code names for debugging as a macro in - internal.h so that it is next to the definition of the opcodes. - -(c) Defined a table of op-code lengths for simpler skipping along compiled - code. This is again a macro in internal.h so that it is next to the - definition of the opcodes. - -34. Added support for recursive calls to individual subpatterns, along the -lines of Robin Houston's patch (but implemented somewhat differently). - -35. Further mods to the Makefile to help Win32. Also, added code to pcregrep to -allow it to read and process whole directories in Win32. This code was -contributed by Lionel Fourquaux; it has not been tested by me. - -36. Added support for named subpatterns. The Python syntax (?P<name>...) is -used to name a group. Names consist of alphanumerics and underscores, and must -be unique. Back references use the syntax (?P=name) and recursive calls use -(?P>name) which is a PCRE extension to the Python extension. Groups still have -numbers. The function pcre_fullinfo() can be used after compilation to extract -a name/number map. There are three relevant calls: - - PCRE_INFO_NAMEENTRYSIZE yields the size of each entry in the map - PCRE_INFO_NAMECOUNT yields the number of entries - PCRE_INFO_NAMETABLE yields a pointer to the map. - -The map is a vector of fixed-size entries. The size of each entry depends on -the length of the longest name used. The first two bytes of each entry are the -group number, most significant byte first. There follows the corresponding -name, zero terminated. The names are in alphabetical order. - -37. Make the maximum literal string in the compiled code 250 for the non-UTF-8 -case instead of 255. Making it the same both with and without UTF-8 support -means that the same test output works with both. - -38. There was a case of malloc(0) in the POSIX testing code in pcretest. Avoid -calling malloc() with a zero argument. - -39. Change 25 above had to resort to a heavy-handed test for the .* anchoring -optimization. I've improved things by keeping a bitmap of backreferences with -numbers 1-31 so that if .* occurs inside capturing brackets that are not in -fact referenced, the optimization can be applied. It is unlikely that a -relevant occurrence of .* (i.e. one which might indicate anchoring or forcing -the match to follow \n) will appear inside brackets with a number greater than -31, but if it does, any back reference > 31 suppresses the optimization. - -40. Added a new compile-time option PCRE_NO_AUTO_CAPTURE. This has the effect -of disabling numbered capturing parentheses. Any opening parenthesis that is -not followed by ? behaves as if it were followed by ?: but named parentheses -can still be used for capturing (and they will acquire numbers in the usual -way). - -41. Redesigned the return codes from the match() function into yes/no/error so -that errors can be passed back from deep inside the nested calls. A malloc -failure while inside a recursive subpattern call now causes the -PCRE_ERROR_NOMEMORY return instead of quietly going wrong. - -42. It is now possible to set a limit on the number of times the match() -function is called in a call to pcre_exec(). This facility makes it possible to -limit the amount of recursion and backtracking, though not in a directly -obvious way, because the match() function is used in a number of different -circumstances. The count starts from zero for each position in the subject -string (for non-anchored patterns). The default limit is, for compatibility, a -large number, namely 10 000 000. You can change this in two ways: - -(a) When configuring PCRE before making, you can use --with-match-limit=n - to set a default value for the compiled library. - -(b) For each call to pcre_exec(), you can pass a pcre_extra block in which - a different value is set. See 45 below. - -If the limit is exceeded, pcre_exec() returns PCRE_ERROR_MATCHLIMIT. - -43. Added a new function pcre_config(int, void *) to enable run-time extraction -of things that can be changed at compile time. The first argument specifies -what is wanted and the second points to where the information is to be placed. -The current list of available information is: - - PCRE_CONFIG_UTF8 - -The output is an integer that is set to one if UTF-8 support is available; -otherwise it is set to zero. - - PCRE_CONFIG_NEWLINE - -The output is an integer that it set to the value of the code that is used for -newline. It is either LF (10) or CR (13). - - PCRE_CONFIG_LINK_SIZE - -The output is an integer that contains the number of bytes used for internal -linkage in compiled expressions. The value is 2, 3, or 4. See item 32 above. - - PCRE_CONFIG_POSIX_MALLOC_THRESHOLD - -The output is an integer that contains the threshold above which the POSIX -interface uses malloc() for output vectors. See item 31 above. - - PCRE_CONFIG_MATCH_LIMIT - -The output is an unsigned integer that contains the default limit of the number -of match() calls in a pcre_exec() execution. See 42 above. - -44. pcretest has been upgraded by the addition of the -C option. This causes it -to extract all the available output from the new pcre_config() function, and to -output it. The program then exits immediately. - -45. A need has arisen to pass over additional data with calls to pcre_exec() in -order to support additional features. One way would have been to define -pcre_exec2() (for example) with extra arguments, but this would not have been -extensible, and would also have required all calls to the original function to -be mapped to the new one. Instead, I have chosen to extend the mechanism that -is used for passing in "extra" data from pcre_study(). - -The pcre_extra structure is now exposed and defined in pcre.h. It currently -contains the following fields: - - flags a bitmap indicating which of the following fields are set - study_data opaque data from pcre_study() - match_limit a way of specifying a limit on match() calls for a specific - call to pcre_exec() - callout_data data for callouts (see 49 below) - -The flag bits are also defined in pcre.h, and are - - PCRE_EXTRA_STUDY_DATA - PCRE_EXTRA_MATCH_LIMIT - PCRE_EXTRA_CALLOUT_DATA - -The pcre_study() function now returns one of these new pcre_extra blocks, with -the actual study data pointed to by the study_data field, and the -PCRE_EXTRA_STUDY_DATA flag set. This can be passed directly to pcre_exec() as -before. That is, this change is entirely upwards-compatible and requires no -change to existing code. - -If you want to pass in additional data to pcre_exec(), you can either place it -in a pcre_extra block provided by pcre_study(), or create your own pcre_extra -block. - -46. pcretest has been extended to test the PCRE_EXTRA_MATCH_LIMIT feature. If a -data string contains the escape sequence \M, pcretest calls pcre_exec() several -times with different match limits, until it finds the minimum value needed for -pcre_exec() to complete. The value is then output. This can be instructive; for -most simple matches the number is quite small, but for pathological cases it -gets very large very quickly. - -47. There's a new option for pcre_fullinfo() called PCRE_INFO_STUDYSIZE. It -returns the size of the data block pointed to by the study_data field in a -pcre_extra block, that is, the value that was passed as the argument to -pcre_malloc() when PCRE was getting memory in which to place the information -created by pcre_study(). The fourth argument should point to a size_t variable. -pcretest has been extended so that this information is shown after a successful -pcre_study() call when information about the compiled regex is being displayed. - -48. Cosmetic change to Makefile: there's no need to have / after $(DESTDIR) -because what follows is always an absolute path. (Later: it turns out that this -is more than cosmetic for MinGW, because it doesn't like empty path -components.) - -49. Some changes have been made to the callout feature (see 28 above): - -(i) A callout function now has three choices for what it returns: - - 0 => success, carry on matching - > 0 => failure at this point, but backtrack if possible - < 0 => serious error, return this value from pcre_exec() - - Negative values should normally be chosen from the set of PCRE_ERROR_xxx - values. In particular, returning PCRE_ERROR_NOMATCH forces a standard - "match failed" error. The error number PCRE_ERROR_CALLOUT is reserved for - use by callout functions. It will never be used by PCRE itself. - -(ii) The pcre_extra structure (see 45 above) has a void * field called - callout_data, with corresponding flag bit PCRE_EXTRA_CALLOUT_DATA. The - pcre_callout_block structure has a field of the same name. The contents of - the field passed in the pcre_extra structure are passed to the callout - function in the corresponding field in the callout block. This makes it - easier to use the same callout-containing regex from multiple threads. For - testing, the pcretest program has a new data escape - - \C*n pass the number n (may be negative) as callout_data - - If the callout function in pcretest receives a non-zero value as - callout_data, it returns that value. - -50. Makefile wasn't handling CFLAGS properly when compiling dftables. Also, -there were some redundant $(CFLAGS) in commands that are now specified as -$(LINK), which already includes $(CFLAGS). - -51. Extensions to UTF-8 support are listed below. These all apply when (a) PCRE -has been compiled with UTF-8 support *and* pcre_compile() has been compiled -with the PCRE_UTF8 flag. Patterns that are compiled without that flag assume -one-byte characters throughout. Note that case-insensitive matching applies -only to characters whose values are less than 256. PCRE doesn't support the -notion of cases for higher-valued characters. - -(i) A character class whose characters are all within 0-255 is handled as - a bit map, and the map is inverted for negative classes. Previously, a - character > 255 always failed to match such a class; however it should - match if the class was a negative one (e.g. [^ab]). This has been fixed. - -(ii) A negated character class with a single character < 255 is coded as - "not this character" (OP_NOT). This wasn't working properly when the test - character was multibyte, either singly or repeated. - -(iii) Repeats of multibyte characters are now handled correctly in UTF-8 - mode, for example: \x{100}{2,3}. - -(iv) The character escapes \b, \B, \d, \D, \s, \S, \w, and \W (either - singly or repeated) now correctly test multibyte characters. However, - PCRE doesn't recognize any characters with values greater than 255 as - digits, spaces, or word characters. Such characters always match \D, \S, - and \W, and never match \d, \s, or \w. - -(v) Classes may now contain characters and character ranges with values - greater than 255. For example: [ab\x{100}-\x{400}]. - -(vi) pcregrep now has a --utf-8 option (synonym -u) which makes it call - PCRE in UTF-8 mode. - -52. The info request value PCRE_INFO_FIRSTCHAR has been renamed -PCRE_INFO_FIRSTBYTE because it is a byte value. However, the old name is -retained for backwards compatibility. (Note that LASTLITERAL is also a byte -value.) - -53. The single man page has become too large. I have therefore split it up into -a number of separate man pages. These also give rise to individual HTML pages; -these are now put in a separate directory, and there is an index.html page that -lists them all. Some hyperlinking between the pages has been installed. - -54. Added convenience functions for handling named capturing parentheses. - -55. Unknown escapes inside character classes (e.g. [\M]) and escapes that -aren't interpreted therein (e.g. [\C]) are literals in Perl. This is now also -true in PCRE, except when the PCRE_EXTENDED option is set, in which case they -are faulted. - -56. Introduced HOST_CC and HOST_CFLAGS which can be set in the environment when -calling configure. These values are used when compiling the dftables.c program -which is run to generate the source of the default character tables. They -default to the values of CC and CFLAGS. If you are cross-compiling PCRE, -you will need to set these values. - -57. Updated the building process for Windows DLL, as provided by Fred Cox. - - -Version 3.9 02-Jan-02 ---------------------- - -1. A bit of extraneous text had somehow crept into the pcregrep documentation. - -2. If --disable-static was given, the building process failed when trying to -build pcretest and pcregrep. (For some reason it was using libtool to compile -them, which is not right, as they aren't part of the library.) - - -Version 3.8 18-Dec-01 ---------------------- - -1. The experimental UTF-8 code was completely screwed up. It was packing the -bytes in the wrong order. How dumb can you get? - - -Version 3.7 29-Oct-01 ---------------------- - -1. In updating pcretest to check change 1 of version 3.6, I screwed up. -This caused pcretest, when used on the test data, to segfault. Unfortunately, -this didn't happen under Solaris 8, where I normally test things. - -2. The Makefile had to be changed to make it work on BSD systems, where 'make' -doesn't seem to recognize that ./xxx and xxx are the same file. (This entry -isn't in ChangeLog distributed with 3.7 because I forgot when I hastily made -this fix an hour or so after the initial 3.7 release.) - - -Version 3.6 23-Oct-01 ---------------------- - -1. Crashed with /(sens|respons)e and \1ibility/ and "sense and sensibility" if -offsets passed as NULL with zero offset count. - -2. The config.guess and config.sub files had not been updated when I moved to -the latest autoconf. - - -Version 3.5 15-Aug-01 ---------------------- - -1. Added some missing #if !defined NOPOSIX conditionals in pcretest.c that -had been forgotten. - -2. By using declared but undefined structures, we can avoid using "void" -definitions in pcre.h while keeping the internal definitions of the structures -private. - -3. The distribution is now built using autoconf 2.50 and libtool 1.4. From a -user point of view, this means that both static and shared libraries are built -by default, but this can be individually controlled. More of the work of -handling this static/shared cases is now inside libtool instead of PCRE's make -file. - -4. The pcretest utility is now installed along with pcregrep because it is -useful for users (to test regexs) and by doing this, it automatically gets -relinked by libtool. The documentation has been turned into a man page, so -there are now .1, .txt, and .html versions in /doc. - -5. Upgrades to pcregrep: - (i) Added long-form option names like gnu grep. - (ii) Added --help to list all options with an explanatory phrase. - (iii) Added -r, --recursive to recurse into sub-directories. - (iv) Added -f, --file to read patterns from a file. - -6. pcre_exec() was referring to its "code" argument before testing that -argument for NULL (and giving an error if it was NULL). - -7. Upgraded Makefile.in to allow for compiling in a different directory from -the source directory. - -8. Tiny buglet in pcretest: when pcre_fullinfo() was called to retrieve the -options bits, the pointer it was passed was to an int instead of to an unsigned -long int. This mattered only on 64-bit systems. - -9. Fixed typo (3.4/1) in pcre.h again. Sigh. I had changed pcre.h (which is -generated) instead of pcre.in, which it its source. Also made the same change -in several of the .c files. - -10. A new release of gcc defines printf() as a macro, which broke pcretest -because it had an ifdef in the middle of a string argument for printf(). Fixed -by using separate calls to printf(). - -11. Added --enable-newline-is-cr and --enable-newline-is-lf to the configure -script, to force use of CR or LF instead of \n in the source. On non-Unix -systems, the value can be set in config.h. - -12. The limit of 200 on non-capturing parentheses is a _nesting_ limit, not an -absolute limit. Changed the text of the error message to make this clear, and -likewise updated the man page. - -13. The limit of 99 on the number of capturing subpatterns has been removed. -The new limit is 65535, which I hope will not be a "real" limit. - - -Version 3.4 22-Aug-00 ---------------------- - -1. Fixed typo in pcre.h: unsigned const char * changed to const unsigned char *. - -2. Diagnose condition (?(0) as an error instead of crashing on matching. - - -Version 3.3 01-Aug-00 ---------------------- - -1. If an octal character was given, but the value was greater than \377, it -was not getting masked to the least significant bits, as documented. This could -lead to crashes in some systems. - -2. Perl 5.6 (if not earlier versions) accepts classes like [a-\d] and treats -the hyphen as a literal. PCRE used to give an error; it now behaves like Perl. - -3. Added the functions pcre_free_substring() and pcre_free_substring_list(). -These just pass their arguments on to (pcre_free)(), but they are provided -because some uses of PCRE bind it to non-C systems that can call its functions, -but cannot call free() or pcre_free() directly. - -4. Add "make test" as a synonym for "make check". Corrected some comments in -the Makefile. - -5. Add $(DESTDIR)/ in front of all the paths in the "install" target in the -Makefile. - -6. Changed the name of pgrep to pcregrep, because Solaris has introduced a -command called pgrep for grepping around the active processes. - -7. Added the beginnings of support for UTF-8 character strings. - -8. Arranged for the Makefile to pass over the settings of CC, CFLAGS, and -RANLIB to ./ltconfig so that they are used by libtool. I think these are all -the relevant ones. (AR is not passed because ./ltconfig does its own figuring -out for the ar command.) - - -Version 3.2 12-May-00 ---------------------- - -This is purely a bug fixing release. - -1. If the pattern /((Z)+|A)*/ was matched agained ZABCDEFG it matched Z instead -of ZA. This was just one example of several cases that could provoke this bug, -which was introduced by change 9 of version 2.00. The code for breaking -infinite loops after an iteration that matches an empty string was't working -correctly. - -2. The pcretest program was not imitating Perl correctly for the pattern /a*/g -when matched against abbab (for example). After matching an empty string, it -wasn't forcing anchoring when setting PCRE_NOTEMPTY for the next attempt; this -caused it to match further down the string than it should. - -3. The code contained an inclusion of sys/types.h. It isn't clear why this -was there because it doesn't seem to be needed, and it causes trouble on some -systems, as it is not a Standard C header. It has been removed. - -4. Made 4 silly changes to the source to avoid stupid compiler warnings that -were reported on the Macintosh. The changes were from - - while ((c = *(++ptr)) != 0 && c != '\n'); -to - while ((c = *(++ptr)) != 0 && c != '\n') ; - -Totally extraordinary, but if that's what it takes... - -5. PCRE is being used in one environment where neither memmove() nor bcopy() is -available. Added HAVE_BCOPY and an autoconf test for it; if neither -HAVE_MEMMOVE nor HAVE_BCOPY is set, use a built-in emulation function which -assumes the way PCRE uses memmove() (always moving upwards). - -6. PCRE is being used in one environment where strchr() is not available. There -was only one use in pcre.c, and writing it out to avoid strchr() probably gives -faster code anyway. - - -Version 3.1 09-Feb-00 ---------------------- - -The only change in this release is the fixing of some bugs in Makefile.in for -the "install" target: - -(1) It was failing to install pcreposix.h. - -(2) It was overwriting the pcre.3 man page with the pcreposix.3 man page. - - -Version 3.0 01-Feb-00 ---------------------- - -1. Add support for the /+ modifier to perltest (to output $` like it does in -pcretest). - -2. Add support for the /g modifier to perltest. - -3. Fix pcretest so that it behaves even more like Perl for /g when the pattern -matches null strings. - -4. Fix perltest so that it doesn't do unwanted things when fed an empty -pattern. Perl treats empty patterns specially - it reuses the most recent -pattern, which is not what we want. Replace // by /(?#)/ in order to avoid this -effect. - -5. The POSIX interface was broken in that it was just handing over the POSIX -captured string vector to pcre_exec(), but (since release 2.00) PCRE has -required a bigger vector, with some working space on the end. This means that -the POSIX wrapper now has to get and free some memory, and copy the results. - -6. Added some simple autoconf support, placing the test data and the -documentation in separate directories, re-organizing some of the -information files, and making it build pcre-config (a GNU standard). Also added -libtool support for building PCRE as a shared library, which is now the -default. - -7. Got rid of the leading zero in the definition of PCRE_MINOR because 08 and -09 are not valid octal constants. Single digits will be used for minor values -less than 10. - -8. Defined REG_EXTENDED and REG_NOSUB as zero in the POSIX header, so that -existing programs that set these in the POSIX interface can use PCRE without -modification. - -9. Added a new function, pcre_fullinfo() with an extensible interface. It can -return all that pcre_info() returns, plus additional data. The pcre_info() -function is retained for compatibility, but is considered to be obsolete. - -10. Added experimental recursion feature (?R) to handle one common case that -Perl 5.6 will be able to do with (?p{...}). - -11. Added support for POSIX character classes like [:alpha:], which Perl is -adopting. - - -Version 2.08 31-Aug-99 ----------------------- - -1. When startoffset was not zero and the pattern began with ".*", PCRE was not -trying to match at the startoffset position, but instead was moving forward to -the next newline as if a previous match had failed. - -2. pcretest was not making use of PCRE_NOTEMPTY when repeating for /g and /G, -and could get into a loop if a null string was matched other than at the start -of the subject. - -3. Added definitions of PCRE_MAJOR and PCRE_MINOR to pcre.h so the version can -be distinguished at compile time, and for completeness also added PCRE_DATE. - -5. Added Paul Sokolovsky's minor changes to make it easy to compile a Win32 DLL -in GnuWin32 environments. - - -Version 2.07 29-Jul-99 ----------------------- - -1. The documentation is now supplied in plain text form and HTML as well as in -the form of man page sources. - -2. C++ compilers don't like assigning (void *) values to other pointer types. -In particular this affects malloc(). Although there is no problem in Standard -C, I've put in casts to keep C++ compilers happy. - -3. Typo on pcretest.c; a cast of (unsigned char *) in the POSIX regexec() call -should be (const char *). - -4. If NOPOSIX is defined, pcretest.c compiles without POSIX support. This may -be useful for non-Unix systems who don't want to bother with the POSIX stuff. -However, I haven't made this a standard facility. The documentation doesn't -mention it, and the Makefile doesn't support it. - -5. The Makefile now contains an "install" target, with editable destinations at -the top of the file. The pcretest program is not installed. - -6. pgrep -V now gives the PCRE version number and date. - -7. Fixed bug: a zero repetition after a literal string (e.g. /abcde{0}/) was -causing the entire string to be ignored, instead of just the last character. - -8. If a pattern like /"([^\\"]+|\\.)*"/ is applied in the normal way to a -non-matching string, it can take a very, very long time, even for strings of -quite modest length, because of the nested recursion. PCRE now does better in -some of these cases. It does this by remembering the last required literal -character in the pattern, and pre-searching the subject to ensure it is present -before running the real match. In other words, it applies a heuristic to detect -some types of certain failure quickly, and in the above example, if presented -with a string that has no trailing " it gives "no match" very quickly. - -9. A new runtime option PCRE_NOTEMPTY causes null string matches to be ignored; -other alternatives are tried instead. - - -Version 2.06 09-Jun-99 ----------------------- - -1. Change pcretest's output for amount of store used to show just the code -space, because the remainder (the data block) varies in size between 32-bit and -64-bit systems. - -2. Added an extra argument to pcre_exec() to supply an offset in the subject to -start matching at. This allows lookbehinds to work when searching for multiple -occurrences in a string. - -3. Added additional options to pcretest for testing multiple occurrences: - - /+ outputs the rest of the string that follows a match - /g loops for multiple occurrences, using the new startoffset argument - /G loops for multiple occurrences by passing an incremented pointer - -4. PCRE wasn't doing the "first character" optimization for patterns starting -with \b or \B, though it was doing it for other lookbehind assertions. That is, -it wasn't noticing that a match for a pattern such as /\bxyz/ has to start with -the letter 'x'. On long subject strings, this gives a significant speed-up. - - -Version 2.05 21-Apr-99 ----------------------- - -1. Changed the type of magic_number from int to long int so that it works -properly on 16-bit systems. - -2. Fixed a bug which caused patterns starting with .* not to work correctly -when the subject string contained newline characters. PCRE was assuming -anchoring for such patterns in all cases, which is not correct because .* will -not pass a newline unless PCRE_DOTALL is set. It now assumes anchoring only if -DOTALL is set at top level; otherwise it knows that patterns starting with .* -must be retried after every newline in the subject. - - -Version 2.04 18-Feb-99 ----------------------- - -1. For parenthesized subpatterns with repeats whose minimum was zero, the -computation of the store needed to hold the pattern was incorrect (too large). -If such patterns were nested a few deep, this could multiply and become a real -problem. - -2. Added /M option to pcretest to show the memory requirement of a specific -pattern. Made -m a synonym of -s (which does this globally) for compatibility. - -3. Subpatterns of the form (regex){n,m} (i.e. limited maximum) were being -compiled in such a way that the backtracking after subsequent failure was -pessimal. Something like (a){0,3} was compiled as (a)?(a)?(a)? instead of -((a)((a)(a)?)?)? with disastrous performance if the maximum was of any size. - - -Version 2.03 02-Feb-99 ----------------------- - -1. Fixed typo and small mistake in man page. - -2. Added 4th condition (GPL supersedes if conflict) and created separate -LICENCE file containing the conditions. - -3. Updated pcretest so that patterns such as /abc\/def/ work like they do in -Perl, that is the internal \ allows the delimiter to be included in the -pattern. Locked out the use of \ as a delimiter. If \ immediately follows -the final delimiter, add \ to the end of the pattern (to test the error). - -4. Added the convenience functions for extracting substrings after a successful -match. Updated pcretest to make it able to test these functions. - - -Version 2.02 14-Jan-99 ----------------------- - -1. Initialized the working variables associated with each extraction so that -their saving and restoring doesn't refer to uninitialized store. - -2. Put dummy code into study.c in order to trick the optimizer of the IBM C -compiler for OS/2 into generating correct code. Apparently IBM isn't going to -fix the problem. - -3. Pcretest: the timing code wasn't using LOOPREPEAT for timing execution -calls, and wasn't printing the correct value for compiling calls. Increased the -default value of LOOPREPEAT, and the number of significant figures in the -times. - -4. Changed "/bin/rm" in the Makefile to "-rm" so it works on Windows NT. - -5. Renamed "deftables" as "dftables" to get it down to 8 characters, to avoid -a building problem on Windows NT with a FAT file system. - - -Version 2.01 21-Oct-98 ----------------------- - -1. Changed the API for pcre_compile() to allow for the provision of a pointer -to character tables built by pcre_maketables() in the current locale. If NULL -is passed, the default tables are used. - - -Version 2.00 24-Sep-98 ----------------------- - -1. Since the (>?) facility is in Perl 5.005, don't require PCRE_EXTRA to enable -it any more. - -2. Allow quantification of (?>) groups, and make it work correctly. - -3. The first character computation wasn't working for (?>) groups. - -4. Correct the implementation of \Z (it is permitted to match on the \n at the -end of the subject) and add 5.005's \z, which really does match only at the -very end of the subject. - -5. Remove the \X "cut" facility; Perl doesn't have it, and (?> is neater. - -6. Remove the ability to specify CASELESS, MULTILINE, DOTALL, and -DOLLAR_END_ONLY at runtime, to make it possible to implement the Perl 5.005 -localized options. All options to pcre_study() were also removed. - -7. Add other new features from 5.005: - - $(?<= positive lookbehind - $(?<! negative lookbehind - (?imsx-imsx) added the unsetting capability - such a setting is global if at outer level; local otherwise - (?imsx-imsx:) non-capturing groups with option setting - (?(cond)re|re) conditional pattern matching - - A backreference to itself in a repeated group matches the previous - captured string. - -8. General tidying up of studying (both automatic and via "study") -consequential on the addition of new assertions. - -9. As in 5.005, unlimited repeated groups that could match an empty substring -are no longer faulted at compile time. Instead, the loop is forcibly broken at -runtime if any iteration does actually match an empty substring. - -10. Include the RunTest script in the distribution. - -11. Added tests from the Perl 5.005_02 distribution. This showed up a few -discrepancies, some of which were old and were also with respect to 5.004. They -have now been fixed. - - -Version 1.09 28-Apr-98 ----------------------- - -1. A negated single character class followed by a quantifier with a minimum -value of one (e.g. [^x]{1,6} ) was not compiled correctly. This could lead to -program crashes, or just wrong answers. This did not apply to negated classes -containing more than one character, or to minima other than one. - - -Version 1.08 27-Mar-98 ----------------------- - -1. Add PCRE_UNGREEDY to invert the greediness of quantifiers. - -2. Add (?U) and (?X) to set PCRE_UNGREEDY and PCRE_EXTRA respectively. The -latter must appear before anything that relies on it in the pattern. - - -Version 1.07 16-Feb-98 ----------------------- - -1. A pattern such as /((a)*)*/ was not being diagnosed as in error (unlimited -repeat of a potentially empty string). - - -Version 1.06 23-Jan-98 ----------------------- - -1. Added Markus Oberhumer's little patches for C++. - -2. Literal strings longer than 255 characters were broken. - - -Version 1.05 23-Dec-97 ----------------------- - -1. Negated character classes containing more than one character were failing if -PCRE_CASELESS was set at run time. - - -Version 1.04 19-Dec-97 ----------------------- - -1. Corrected the man page, where some "const" qualifiers had been omitted. - -2. Made debugging output print "{0,xxx}" instead of just "{,xxx}" to agree with -input syntax. - -3. Fixed memory leak which occurred when a regex with back references was -matched with an offsets vector that wasn't big enough. The temporary memory -that is used in this case wasn't being freed if the match failed. - -4. Tidied pcretest to ensure it frees memory that it gets. - -5. Temporary memory was being obtained in the case where the passed offsets -vector was exactly big enough. - -6. Corrected definition of offsetof() from change 5 below. - -7. I had screwed up change 6 below and broken the rules for the use of -setjmp(). Now fixed. - - -Version 1.03 18-Dec-97 ----------------------- - -1. A erroneous regex with a missing opening parenthesis was correctly -diagnosed, but PCRE attempted to access brastack[-1], which could cause crashes -on some systems. - -2. Replaced offsetof(real_pcre, code) by offsetof(real_pcre, code[0]) because -it was reported that one broken compiler failed on the former because "code" is -also an independent variable. - -3. The erroneous regex a[]b caused an array overrun reference. - -4. A regex ending with a one-character negative class (e.g. /[^k]$/) did not -fail on data ending with that character. (It was going on too far, and checking -the next character, typically a binary zero.) This was specific to the -optimized code for single-character negative classes. - -5. Added a contributed patch from the TIN world which does the following: - - + Add an undef for memmove, in case the the system defines a macro for it. - - + Add a definition of offsetof(), in case there isn't one. (I don't know - the reason behind this - offsetof() is part of the ANSI standard - but - it does no harm). - - + Reduce the ifdef's in pcre.c using macro DPRINTF, thereby eliminating - most of the places where whitespace preceded '#'. I have given up and - allowed the remaining 2 cases to be at the margin. - - + Rename some variables in pcre to eliminate shadowing. This seems very - pedantic, but does no harm, of course. - -6. Moved the call to setjmp() into its own function, to get rid of warnings -from gcc -Wall, and avoided calling it at all unless PCRE_EXTRA is used. - -7. Constructs such as \d{8,} were compiling into the equivalent of -\d{8}\d{0,65527} instead of \d{8}\d* which didn't make much difference to the -outcome, but in this particular case used more store than had been allocated, -which caused the bug to be discovered because it threw up an internal error. - -8. The debugging code in both pcre and pcretest for outputting the compiled -form of a regex was going wrong in the case of back references followed by -curly-bracketed repeats. - - -Version 1.02 12-Dec-97 ----------------------- - -1. Typos in pcre.3 and comments in the source fixed. - -2. Applied a contributed patch to get rid of places where it used to remove -'const' from variables, and fixed some signed/unsigned and uninitialized -variable warnings. - -3. Added the "runtest" target to Makefile. - -4. Set default compiler flag to -O2 rather than just -O. - - -Version 1.01 19-Nov-97 ----------------------- - -1. PCRE was failing to diagnose unlimited repeat of empty string for patterns -like /([ab]*)*/, that is, for classes with more than one character in them. - -2. Likewise, it wasn't diagnosing patterns with "once-only" subpatterns, such -as /((?>a*))*/ (a PCRE_EXTRA facility). - - -Version 1.00 18-Nov-97 ----------------------- - -1. Added compile-time macros to support systems such as SunOS4 which don't have -memmove() or strerror() but have other things that can be used instead. - -2. Arranged that "make clean" removes the executables. - - -Version 0.99 27-Oct-97 ----------------------- - -1. Fixed bug in code for optimizing classes with only one character. It was -initializing a 32-byte map regardless, which could cause it to run off the end -of the memory it had got. - -2. Added, conditional on PCRE_EXTRA, the proposed (?>REGEX) construction. - - -Version 0.98 22-Oct-97 ----------------------- - -1. Fixed bug in code for handling temporary memory usage when there are more -back references than supplied space in the ovector. This could cause segfaults. - - -Version 0.97 21-Oct-97 ----------------------- - -1. Added the \X "cut" facility, conditional on PCRE_EXTRA. - -2. Optimized negated single characters not to use a bit map. - -3. Brought error texts together as macro definitions; clarified some of them; -fixed one that was wrong - it said "range out of order" when it meant "invalid -escape sequence". - -4. Changed some char * arguments to const char *. - -5. Added PCRE_NOTBOL and PCRE_NOTEOL (from POSIX). - -6. Added the POSIX-style API wrapper in pcreposix.a and testing facilities in -pcretest. - - -Version 0.96 16-Oct-97 ----------------------- - -1. Added a simple "pgrep" utility to the distribution. - -2. Fixed an incompatibility with Perl: "{" is now treated as a normal character -unless it appears in one of the precise forms "{ddd}", "{ddd,}", or "{ddd,ddd}" -where "ddd" means "one or more decimal digits". - -3. Fixed serious bug. If a pattern had a back reference, but the call to -pcre_exec() didn't supply a large enough ovector to record the related -identifying subpattern, the match always failed. PCRE now remembers the number -of the largest back reference, and gets some temporary memory in which to save -the offsets during matching if necessary, in order to ensure that -backreferences always work. - -4. Increased the compatibility with Perl in a number of ways: - - (a) . no longer matches \n by default; an option PCRE_DOTALL is provided - to request this handling. The option can be set at compile or exec time. - - (b) $ matches before a terminating newline by default; an option - PCRE_DOLLAR_ENDONLY is provided to override this (but not in multiline - mode). The option can be set at compile or exec time. - - (c) The handling of \ followed by a digit other than 0 is now supposed to be - the same as Perl's. If the decimal number it represents is less than 10 - or there aren't that many previous left capturing parentheses, an octal - escape is read. Inside a character class, it's always an octal escape, - even if it is a single digit. - - (d) An escaped but undefined alphabetic character is taken as a literal, - unless PCRE_EXTRA is set. Currently this just reserves the remaining - escapes. - - (e) {0} is now permitted. (The previous item is removed from the compiled - pattern). - -5. Changed all the names of code files so that the basic parts are no longer -than 10 characters, and abolished the teeny "globals.c" file. - -6. Changed the handling of character classes; they are now done with a 32-byte -bit map always. - -7. Added the -d and /D options to pcretest to make it possible to look at the -internals of compilation without having to recompile pcre. - - -Version 0.95 23-Sep-97 ----------------------- - -1. Fixed bug in pre-pass concerning escaped "normal" characters such as \x5c or -\x20 at the start of a run of normal characters. These were being treated as -real characters, instead of the source characters being re-checked. - - -Version 0.94 18-Sep-97 ----------------------- - -1. The functions are now thread-safe, with the caveat that the global variables -containing pointers to malloc() and free() or alternative functions are the -same for all threads. - -2. Get pcre_study() to generate a bitmap of initial characters for non- -anchored patterns when this is possible, and use it if passed to pcre_exec(). - - -Version 0.93 15-Sep-97 ----------------------- - -1. /(b)|(:+)/ was computing an incorrect first character. - -2. Add pcre_study() to the API and the passing of pcre_extra to pcre_exec(), -but not actually doing anything yet. - -3. Treat "-" characters in classes that cannot be part of ranges as literals, -as Perl does (e.g. [-az] or [az-]). - -4. Set the anchored flag if a branch starts with .* or .*? because that tests -all possible positions. - -5. Split up into different modules to avoid including unneeded functions in a -compiled binary. However, compile and exec are still in one module. The "study" -function is split off. - -6. The character tables are now in a separate module whose source is generated -by an auxiliary program - but can then be edited by hand if required. There are -now no calls to isalnum(), isspace(), isdigit(), isxdigit(), tolower() or -toupper() in the code. - -7. Turn the malloc/free funtions variables into pcre_malloc and pcre_free and -make them global. Abolish the function for setting them, as the caller can now -set them directly. - - -Version 0.92 11-Sep-97 ----------------------- - -1. A repeat with a fixed maximum and a minimum of 1 for an ordinary character -(e.g. /a{1,3}/) was broken (I mis-optimized it). - -2. Caseless matching was not working in character classes if the characters in -the pattern were in upper case. - -3. Make ranges like [W-c] work in the same way as Perl for caseless matching. - -4. Make PCRE_ANCHORED public and accept as a compile option. - -5. Add an options word to pcre_exec() and accept PCRE_ANCHORED and -PCRE_CASELESS at run time. Add escapes \A and \I to pcretest to cause it to -pass them. - -6. Give an error if bad option bits passed at compile or run time. - -7. Add PCRE_MULTILINE at compile and exec time, and (?m) as well. Add \M to -pcretest to cause it to pass that flag. - -8. Add pcre_info(), to get the number of identifying subpatterns, the stored -options, and the first character, if set. - -9. Recognize C+ or C{n,m} where n >= 1 as providing a fixed starting character. - - -Version 0.91 10-Sep-97 ----------------------- - -1. PCRE was failing to diagnose unlimited repeats of subpatterns that could -match the empty string as in /(a*)*/. It was looping and ultimately crashing. - -2. PCRE was looping on encountering an indefinitely repeated back reference to -a subpattern that had matched an empty string, e.g. /(a|)\1*/. It now does what -Perl does - treats the match as successful. - -**** diff --git a/src/third_party/pcre-8.38/CheckMan b/src/third_party/pcre-8.38/CheckMan deleted file mode 100755 index 480d735481e..00000000000 --- a/src/third_party/pcre-8.38/CheckMan +++ /dev/null @@ -1,67 +0,0 @@ -#! /usr/bin/perl - -# A script to scan PCRE's man pages to check for typos in the control -# sequences.

For information about testing PCRE, see the pcretest -documentation and the comment at the head of the RunTest file. - - -Historical note 1 ------------------ - -Many years ago I implemented some regular expression functions to an algorithm -suggested by Martin Richards. These were not Unix-like in form, and were quite -restricted in what they could do by comparison with Perl. The interesting part -about the algorithm was that the amount of space required to hold the compiled -form of an expression was known in advance. The code to apply an expression did -not operate by backtracking, as the original Henry Spencer code and current -Perl code does, but instead checked all possibilities simultaneously by keeping -a list of current states and checking all of them as it advanced through the -subject string. In the terminology of Jeffrey Friedl's book, it was a "DFA -algorithm", though it was not a traditional Finite State Machine (FSM). When -the pattern was all used up, all remaining states were possible matches, and -the one matching the longest subset of the subject string was chosen. This did -not necessarily maximize the individual wild portions of the pattern, as is -expected in Unix and Perl-style regular expressions. - - -Historical note 2 ------------------ - -By contrast, the code originally written by Henry Spencer (which was -subsequently heavily modified for Perl) compiles the expression twice: once in -a dummy mode in order to find out how much store will be needed, and then for -real. (The Perl version probably doesn't do this any more; I'm talking about -the original library.) The execution function operates by backtracking and -maximizing (or, optionally, minimizing in Perl) the amount of the subject that -matches individual wild portions of the pattern. This is an "NFA algorithm" in -Friedl's terminology. - - -OK, here's the real stuff -------------------------- - -For the set of functions that form the "basic" PCRE library (which are -unrelated to those mentioned above), I tried at first to invent an algorithm -that used an amount of store bounded by a multiple of the number of characters -in the pattern, to save on compiling time. However, because of the greater -complexity in Perl regular expressions, I couldn't do this. In any case, a -first pass through the pattern is helpful for other reasons. - - -Support for 16-bit and 32-bit data strings -------------------------------------------- - -From release 8.30, PCRE supports 16-bit as well as 8-bit data strings; and from -release 8.32, PCRE supports 32-bit data strings. The library can be compiled -in any combination of 8-bit, 16-bit or 32-bit modes, creating up to three -different libraries. In the description that follows, the word "short" is used -for a 16-bit data quantity, and the word "unit" is used for a quantity that is -a byte in 8-bit mode, a short in 16-bit mode and a 32-bit word in 32-bit mode. -However, so as not to over-complicate the text, the names of PCRE functions are -given in 8-bit form only. - - -Computing the memory requirement: how it was --------------------------------------------- - -Up to and including release 6.7, PCRE worked by running a very degenerate first -pass to calculate a maximum store size, and then a second pass to do the real -compile - which might use a bit less than the predicted amount of memory. The -idea was that this would turn out faster than the Henry Spencer code because -the first pass is degenerate and the second pass can just store stuff straight -into the vector, which it knows is big enough. - - -Computing the memory requirement: how it is -------------------------------------------- - -By the time I was working on a potential 6.8 release, the degenerate first pass -had become very complicated and hard to maintain. Indeed one of the early -things I did for 6.8 was to fix Yet Another Bug in the memory computation. Then -I had a flash of inspiration as to how I could run the real compile function in -a "fake" mode that enables it to compute how much memory it would need, while -actually only ever using a few hundred bytes of working memory, and without too -many tests of the mode that might slow it down. So I refactored the compiling -functions to work this way. This got rid of about 600 lines of source. It -should make future maintenance and development easier. As this was such a major -change, I never released 6.8, instead upping the number to 7.0 (other quite -major changes were also present in the 7.0 release). - -A side effect of this work was that the previous limit of 200 on the nesting -depth of parentheses was removed. However, there is a downside: pcre_compile() -runs more slowly than before (30% or more, depending on the pattern) because it -is doing a full analysis of the pattern. My hope was that this would not be a -big issue, and in the event, nobody has commented on it. - -At release 8.34, a limit on the nesting depth of parentheses was re-introduced -(default 250, settable at build time) so as to put a limit on the amount of -system stack used by pcre_compile(). This is a safety feature for environments -with small stacks where the patterns are provided by users. - - -Traditional matching function ------------------------------ - -The "traditional", and original, matching function is called pcre_exec(), and -it implements an NFA algorithm, similar to the original Henry Spencer algorithm -and the way that Perl works. This is not surprising, since it is intended to be -as compatible with Perl as possible. This is the function most users of PCRE -will use most of the time. From release 8.20, if PCRE is compiled with -just-in-time (JIT) support, and studying a compiled pattern with JIT is -successful, the JIT code is run instead of the normal pcre_exec() code, but the -result is the same. - - -Supplementary matching function -------------------------------- - -From PCRE 6.0, there is also a supplementary matching function called -pcre_dfa_exec(). This implements a DFA matching algorithm that searches -simultaneously for all possible matches that start at one point in the subject -string. (Going back to my roots: see Historical Note 1 above.) This function -intreprets the same compiled pattern data as pcre_exec(); however, not all the -facilities are available, and those that are do not always work in quite the -same way. See the user documentation for details. - -The algorithm that is used for pcre_dfa_exec() is not a traditional FSM, -because it may have a number of states active at one time. More work would be -needed at compile time to produce a traditional FSM where only one state is -ever active at once. I believe some other regex matchers work this way. JIT -support is not available for this kind of matching. - - -Changeable options ------------------- - -The /i, /m, or /s options (PCRE_CASELESS, PCRE_MULTILINE, PCRE_DOTALL, and some -others) may change in the middle of patterns. From PCRE 8.13, their processing -is handled entirely at compile time by generating different opcodes for the -different settings. The runtime functions do not need to keep track of an -options state any more. - - -Format of compiled patterns ---------------------------- - -The compiled form of a pattern is a vector of unsigned units (bytes in 8-bit -mode, shorts in 16-bit mode, 32-bit words in 32-bit mode), containing items of -variable length. The first unit in an item contains an opcode, and the length -of the item is either implicit in the opcode or contained in the data that -follows it. - -In many cases listed below, LINK_SIZE data values are specified for offsets -within the compiled pattern. LINK_SIZE always specifies a number of bytes. The -default value for LINK_SIZE is 2, but PCRE can be compiled to use 3-byte or -4-byte values for these offsets, although this impairs the performance. (3-byte -LINK_SIZE values are available only in 8-bit mode.) Specifing a LINK_SIZE -larger than 2 is necessary only when patterns whose compiled length is greater -than 64K are going to be processed. In this description, we assume the "normal" -compilation options. Data values that are counts (e.g. quantifiers) are two -bytes long in 8-bit mode (most significant byte first), or one unit in 16-bit -and 32-bit modes. - - -Opcodes with no following data ------------------------------- - -These items are all just one unit long - - OP_END end of pattern - OP_ANY match any one character other than newline - OP_ALLANY match any one character, including newline - OP_ANYBYTE match any single unit, even in UTF-8/16 mode - OP_SOD match start of data: \A - OP_SOM, start of match (subject + offset): \G - OP_SET_SOM, set start of match (\K) - OP_CIRC ^ (start of data) - OP_CIRCM ^ multiline mode (start of data or after newline) - OP_NOT_WORD_BOUNDARY \W - OP_WORD_BOUNDARY \w - OP_NOT_DIGIT \D - OP_DIGIT \d - OP_NOT_HSPACE \H - OP_HSPACE \h - OP_NOT_WHITESPACE \S - OP_WHITESPACE \s - OP_NOT_VSPACE \V - OP_VSPACE \v - OP_NOT_WORDCHAR \W - OP_WORDCHAR \w - OP_EODN match end of data or newline at end: \Z - OP_EOD match end of data: \z - OP_DOLL $ (end of data, or before final newline) - OP_DOLLM $ multiline mode (end of data or before newline) - OP_EXTUNI match an extended Unicode grapheme cluster - OP_ANYNL match any Unicode newline sequence - - OP_ASSERT_ACCEPT ) - OP_ACCEPT ) These are Perl 5.10's "backtracking control - OP_COMMIT ) verbs". If OP_ACCEPT is inside capturing - OP_FAIL ) parentheses, it may be preceded by one or more - OP_PRUNE ) OP_CLOSE, each followed by a count that - OP_SKIP ) indicates which parentheses must be closed. - OP_THEN ) - -OP_ASSERT_ACCEPT is used when (*ACCEPT) is encountered within an assertion. -This ends the assertion, not the entire pattern match. - - -Backtracking control verbs with optional data ---------------------------------------------- - -(*THEN) without an argument generates the opcode OP_THEN and no following data. -OP_MARK is followed by the mark name, preceded by a one-unit length, and -followed by a binary zero. For (*PRUNE), (*SKIP), and (*THEN) with arguments, -the opcodes OP_PRUNE_ARG, OP_SKIP_ARG, and OP_THEN_ARG are used, with the name -following in the same format as OP_MARK. - - -Matching literal characters ---------------------------- - -The OP_CHAR opcode is followed by a single character that is to be matched -casefully. For caseless matching, OP_CHARI is used. In UTF-8 or UTF-16 modes, -the character may be more than one unit long. In UTF-32 mode, characters -are always exactly one unit long. - -If there is only one character in a character class, OP_CHAR or OP_CHARI is -used for a positive class, and OP_NOT or OP_NOTI for a negative one (that is, -for something like [^a]). - - -Repeating single characters ---------------------------- - -The common repeats (*, +, ?), when applied to a single character, use the -following opcodes, which come in caseful and caseless versions: - - Caseful Caseless - OP_STAR OP_STARI - OP_MINSTAR OP_MINSTARI - OP_POSSTAR OP_POSSTARI - OP_PLUS OP_PLUSI - OP_MINPLUS OP_MINPLUSI - OP_POSPLUS OP_POSPLUSI - OP_QUERY OP_QUERYI - OP_MINQUERY OP_MINQUERYI - OP_POSQUERY OP_POSQUERYI - -Each opcode is followed by the character that is to be repeated. In ASCII mode, -these are two-unit items; in UTF-8 or UTF-16 modes, the length is variable; in -UTF-32 mode these are one-unit items. Those with "MIN" in their names are the -minimizing versions. Those with "POS" in their names are possessive versions. -Other repeats make use of these opcodes: - - Caseful Caseless - OP_UPTO OP_UPTOI - OP_MINUPTO OP_MINUPTOI - OP_POSUPTO OP_POSUPTOI - OP_EXACT OP_EXACTI - -Each of these is followed by a count and then the repeated character. OP_UPTO -matches from 0 to the given number. A repeat with a non-zero minimum and a -fixed maximum is coded as an OP_EXACT followed by an OP_UPTO (or OP_MINUPTO or -OPT_POSUPTO). - -Another set of matching repeating opcodes (called OP_NOTSTAR, OP_NOTSTARI, -etc.) are used for repeated, negated, single-character classes such as [^a]*. -The normal single-character opcodes (OP_STAR, etc.) are used for repeated -positive single-character classes. - - -Repeating character types -------------------------- - -Repeats of things like \d are done exactly as for single characters, except -that instead of a character, the opcode for the type is stored in the data -unit. The opcodes are: - - OP_TYPESTAR - OP_TYPEMINSTAR - OP_TYPEPOSSTAR - OP_TYPEPLUS - OP_TYPEMINPLUS - OP_TYPEPOSPLUS - OP_TYPEQUERY - OP_TYPEMINQUERY - OP_TYPEPOSQUERY - OP_TYPEUPTO - OP_TYPEMINUPTO - OP_TYPEPOSUPTO - OP_TYPEEXACT - - -Match by Unicode property -------------------------- - -OP_PROP and OP_NOTPROP are used for positive and negative matches of a -character by testing its Unicode property (the \p and \P escape sequences). -Each is followed by two units that encode the desired property as a type and a -value. The types are a set of #defines of the form PT_xxx, and the values are -enumerations of the form ucp_xx, defined in the ucp.h source file. The value is -relevant only for PT_GC (General Category), PT_PC (Particular Category), and -PT_SC (Script). - -Repeats of these items use the OP_TYPESTAR etc. set of opcodes, followed by -three units: OP_PROP or OP_NOTPROP, and then the desired property type and -value. - - -Character classes ------------------ - -If there is only one character in a class, OP_CHAR or OP_CHARI is used for a -positive class, and OP_NOT or OP_NOTI for a negative one (that is, for -something like [^a]). - -A set of repeating opcodes (called OP_NOTSTAR etc.) are used for repeated, -negated, single-character classes. The normal single-character opcodes -(OP_STAR, etc.) are used for repeated positive single-character classes. - -When there is more than one character in a class, and all the code points are -less than 256, OP_CLASS is used for a positive class, and OP_NCLASS for a -negative one. In either case, the opcode is followed by a 32-byte (16-short, -8-word) bit map containing a 1 bit for every character that is acceptable. The -bits are counted from the least significant end of each unit. In caseless mode, -bits for both cases are set. - -The reason for having both OP_CLASS and OP_NCLASS is so that, in UTF-8/16/32 -mode, subject characters with values greater than 255 can be handled correctly. -For OP_CLASS they do not match, whereas for OP_NCLASS they do. - -For classes containing characters with values greater than 255 or that contain -\p or \P, OP_XCLASS is used. It optionally uses a bit map if any code points -are less than 256, followed by a list of pairs (for a range) and single -characters. In caseless mode, both cases are explicitly listed. - -OP_XCLASS is followed by a unit containing flag bits: XCL_NOT indicates that -this is a negative class, and XCL_MAP indicates that a bit map is present. -There follows the bit map, if XCL_MAP is set, and then a sequence of items -coded as follows: - - XCL_END marks the end of the list - XCL_SINGLE one character follows - XCL_RANGE two characters follow - XCL_PROP a Unicode property (type, value) follows - XCL_NOTPROP a Unicode property (type, value) follows - -If a range starts with a code point less than 256 and ends with one greater -than 256, an XCL_RANGE item is used, without setting any bits in the bit map. -This means that if no other items in the class set bits in the map, a map is -not needed. - - -Back references ---------------- - -OP_REF (caseful) or OP_REFI (caseless) is followed by a count containing the -reference number if the reference is to a unique capturing group (either by -number or by name). When named groups are used, there may be more than one -group with the same name. In this case, a reference by name generates OP_DNREF -or OP_DNREFI. These are followed by two counts: the index (not the byte offset) -in the group name table of the first entry for the requred name, followed by -the number of groups with the same name. - - -Repeating character classes and back references ------------------------------------------------ - -Single-character classes are handled specially (see above). This section -applies to other classes and also to back references. In both cases, the repeat -information follows the base item. The matching code looks at the following -opcode to see if it is one of - - OP_CRSTAR - OP_CRMINSTAR - OP_CRPOSSTAR - OP_CRPLUS - OP_CRMINPLUS - OP_CRPOSPLUS - OP_CRQUERY - OP_CRMINQUERY - OP_CRPOSQUERY - OP_CRRANGE - OP_CRMINRANGE - OP_CRPOSRANGE - -All but the last three are single-unit items, with no data. The others are -followed by the minimum and maximum repeat counts. - - -Brackets and alternation ------------------------- - -A pair of non-capturing round brackets is wrapped round each expression at -compile time, so alternation always happens in the context of brackets. - -[Note for North Americans: "bracket" to some English speakers, including -myself, can be round, square, curly, or pointy. Hence this usage rather than -"parentheses".] - -Non-capturing brackets use the opcode OP_BRA. Originally PCRE was limited to 99 -capturing brackets and it used a different opcode for each one. From release -3.5, the limit was removed by putting the bracket number into the data for -higher-numbered brackets. From release 7.0 all capturing brackets are handled -this way, using the single opcode OP_CBRA. - -A bracket opcode is followed by LINK_SIZE bytes which give the offset to the -next alternative OP_ALT or, if there aren't any branches, to the matching -OP_KET opcode. Each OP_ALT is followed by LINK_SIZE bytes giving the offset to -the next one, or to the OP_KET opcode. For capturing brackets, the bracket -number is a count that immediately follows the offset. - -OP_KET is used for subpatterns that do not repeat indefinitely, and OP_KETRMIN -and OP_KETRMAX are used for indefinite repetitions, minimally or maximally -respectively (see below for possessive repetitions). All three are followed by -LINK_SIZE bytes giving (as a positive number) the offset back to the matching -bracket opcode. - -If a subpattern is quantified such that it is permitted to match zero times, it -is preceded by one of OP_BRAZERO, OP_BRAMINZERO, or OP_SKIPZERO. These are -single-unit opcodes that tell the matcher that skipping the following -subpattern entirely is a valid branch. In the case of the first two, not -skipping the pattern is also valid (greedy and non-greedy). The third is used -when a pattern has the quantifier {0,0}. It cannot be entirely discarded, -because it may be called as a subroutine from elsewhere in the regex. - -A subpattern with an indefinite maximum repetition is replicated in the -compiled data its minimum number of times (or once with OP_BRAZERO if the -minimum is zero), with the final copy terminating with OP_KETRMIN or OP_KETRMAX -as appropriate. - -A subpattern with a bounded maximum repetition is replicated in a nested -fashion up to the maximum number of times, with OP_BRAZERO or OP_BRAMINZERO -before each replication after the minimum, so that, for example, (abc){2,5} is -compiled as (abc)(abc)((abc)((abc)(abc)?)?)?, except that each bracketed group -has the same number. - -When a repeated subpattern has an unbounded upper limit, it is checked to see -whether it could match an empty string. If this is the case, the opcode in the -final replication is changed to OP_SBRA or OP_SCBRA. This tells the matcher -that it needs to check for matching an empty string when it hits OP_KETRMIN or -OP_KETRMAX, and if so, to break the loop. - - -Possessive brackets -------------------- - -When a repeated group (capturing or non-capturing) is marked as possessive by -the "+" notation, e.g. (abc)++, different opcodes are used. Their names all -have POS on the end, e.g. OP_BRAPOS instead of OP_BRA and OP_SCPBRPOS instead -of OP_SCBRA. The end of such a group is marked by OP_KETRPOS. If the minimum -repetition is zero, the group is preceded by OP_BRAPOSZERO. - - -Once-only (atomic) groups -------------------------- - -These are just like other subpatterns, but they start with the opcode -OP_ONCE or OP_ONCE_NC. The former is used when there are no capturing brackets -within the atomic group; the latter when there are. The distinction is needed -for when there is a backtrack to before the group - any captures within the -group must be reset, so it is necessary to retain backtracking points inside -the group even after it is complete in order to do this. When there are no -captures in an atomic group, all the backtracking can be discarded when it is -complete. This is more efficient, and also uses less stack. - -The check for matching an empty string in an unbounded repeat is handled -entirely at runtime, so there are just these two opcodes for atomic groups. - - -Assertions ----------- - -Forward assertions are also just like other subpatterns, but starting with one -of the opcodes OP_ASSERT or OP_ASSERT_NOT. Backward assertions use the opcodes -OP_ASSERTBACK and OP_ASSERTBACK_NOT, and the first opcode inside the assertion -is OP_REVERSE, followed by a count of the number of characters to move back the -pointer in the subject string. In ASCII mode, the count is a number of units, -but in UTF-8/16 mode each character may occupy more than one unit; in UTF-32 -mode each character occupies exactly one unit. A separate count is present in -each alternative of a lookbehind assertion, allowing them to have different -fixed lengths. - - -Conditional subpatterns ------------------------ - -These are like other subpatterns, but they start with the opcode OP_COND, or -OP_SCOND for one that might match an empty string in an unbounded repeat. If -the condition is a back reference, this is stored at the start of the -subpattern using the opcode OP_CREF followed by a count containing the -reference number, provided that the reference is to a unique capturing group. -If the reference was by name and there is more than one group with that name, -OP_DNCREF is used instead. It is followed by two counts: the index in the group -names table, and the number of groups with the same name. - -If the condition is "in recursion" (coded as "(?(R)"), or "in recursion of -group x" (coded as "(?(Rx)"), the group number is stored at the start of the -subpattern using the opcode OP_RREF (with a value of zero for "the whole -pattern") or OP_DNRREF (with data as for OP_DNCREF). For a DEFINE condition, -just the single unit OP_DEF is used (it has no associated data). Otherwise, a -conditional subpattern always starts with one of the assertions. - - -Recursion ---------- - -Recursion either matches the current regex, or some subexpression. The opcode -OP_RECURSE is followed by aLINK_SIZE value that is the offset to the starting -bracket from the start of the whole pattern. From release 6.5, OP_RECURSE is -automatically wrapped inside OP_ONCE brackets, because otherwise some patterns -broke it. OP_RECURSE is also used for "subroutine" calls, even though they are -not strictly a recursion. - - -Callout -------- - -OP_CALLOUT is followed by one unit of data that holds a callout number in the -range 0 to 254 for manual callouts, or 255 for an automatic callout. In both -cases there follows a count giving the offset in the pattern string to the -start of the following item, and another count giving the length of this item. -These values make is possible for pcretest to output useful tracing information -using automatic callouts. - -Philip Hazel -November 2013 diff --git a/src/third_party/pcre-8.38/INSTALL b/src/third_party/pcre-8.38/INSTALL deleted file mode 100644 index 2099840756e..00000000000 --- a/src/third_party/pcre-8.38/INSTALL +++ /dev/null @@ -1,370 +0,0 @@ -Installation Instructions -************************* - -Copyright (C) 1994-1996, 1999-2002, 2004-2013 Free Software Foundation, -Inc. - - Copying and distribution of this file, with or without modification, -are permitted in any medium without royalty provided the copyright -notice and this notice are preserved.

When installing into a prefix owned by root, it is - recommended that the package be configured and built as a regular - user, and only the `make install' phase executed with root - privileges. - - 5. Optionally, type `make installcheck' to repeat any self-tests, but - this time using the binaries in their final installed location. - This target does not install anything. Running this target as a - regular user, particularly if the prior `make install' required - root privileges, verifies that the installation completed - correctly. - - 6. You can remove the program binaries and object files from the - source code directory by typing `make clean'. To also remove the - files that `configure' created (so you can compile the package for - a different kind of computer), type `make distclean'. There is - also a `make maintainer-clean' target, but that is intended mainly - for the package's developers. If you use it, you may have to get - all sorts of other programs in order to regenerate files that came - with the distribution. - - 7. Often, you can also type `make uninstall' to remove the installed - files again. In practice, not all packages have tested that - uninstallation works correctly, even though it is required by the - GNU Coding Standards. - - 8. Some packages, particularly those that use Automake, provide `make - distcheck', which can by used by developers to test that all other - targets like `make install' and `make uninstall' work correctly. - This target is generally not run by end users. - -Compilers and Options -===================== - - Some systems require unusual options for compilation or linking that -the `configure' script does not know about. Run `./configure --help' -for details on some of the pertinent environment variables. - - You can give `configure' initial values for configuration parameters -by setting variables in the command line or in the environment. Here -is an example: - - ./configure CC=c99 CFLAGS=-g LIBS=-lposix - - *Note Defining Variables::, for more details. - -Compiling For Multiple Architectures -==================================== - - You can compile the package for more than one kind of computer at the -same time, by placing the object files for each architecture in their -own directory. To do this, you can use GNU `make'. `cd' to the -directory where you want the object files and executables to go and run -the `configure' script. `configure' automatically checks for the -source code in the directory that `configure' is in and in `..'. This -is known as a "VPATH" build. - - With a non-GNU `make', it is safer to compile the package for one -architecture at a time in the source code directory. After you have -installed the package for one architecture, use `make distclean' before -reconfiguring for another architecture. - - On MacOS X 10.5 and later systems, you can create libraries and -executables that work on multiple system types--known as "fat" or -"universal" binaries--by specifying multiple `-arch' options to the -compiler but only a single `-arch' option to the preprocessor. Like -this: - - ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ - CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ - CPP="gcc -E" CXXCPP="g++ -E" - - This is not guaranteed to produce working output in all cases, you -may have to build one architecture at a time and combine the results -using the `lipo' tool if you have problems. - -Installation Names -================== - - By default, `make install' installs the package's commands under -`/usr/local/bin', include files under `/usr/local/include', etc. You -can specify an installation prefix other than `/usr/local' by giving -`configure' the option `--prefix=PREFIX', where PREFIX must be an -absolute file name. - - You can specify separate installation prefixes for -architecture-specific files and architecture-independent files. If you -pass the option `--exec-prefix=PREFIX' to `configure', the package uses -PREFIX as the prefix for installing programs and libraries. -Documentation and other data files still use the regular prefix. - - In addition, if you use an unusual directory layout you can give -options like `--bindir=DIR' to specify different values for particular -kinds of files. Run `configure --help' for a list of the directories -you can set and what kinds of files go in them. In general, the -default for these options is expressed in terms of `${prefix}', so that -specifying just `--prefix' will affect all of the other directory -specifications that were not explicitly provided. - - The most portable way to affect installation locations is to pass the -correct locations to `configure'; however, many packages provide one or -both of the following shortcuts of passing variable assignments to the -`make install' command line to change installation locations without -having to reconfigure or recompile. - - The first method involves providing an override variable for each -affected directory. For example, `make install -prefix=/alternate/directory' will choose an alternate location for all -directory configuration variables that were expressed in terms of -`${prefix}'. Any directories that were specified during `configure', -but not in terms of `${prefix}', must each be overridden at install -time for the entire installation to be relocated. The approach of -makefile variable overrides for each directory variable is required by -the GNU Coding Standards, and ideally causes no recompilation. -However, some platforms have known limitations with the semantics of -shared libraries that end up requiring recompilation when using this -method, particularly noticeable in packages that use GNU Libtool. - - The second method involves providing the `DESTDIR' variable. For -example, `make install DESTDIR=/alternate/directory' will prepend -`/alternate/directory' before all installation names. The approach of -`DESTDIR' overrides is not required by the GNU Coding Standards, and -does not work on platforms that have drive letters. On the other hand, -it does better at avoiding recompilation issues, and works well even -when some directory options were not specified in terms of `${prefix}' -at `configure' time. - -Optional Features -================= - - If the package supports it, you can cause programs to be installed -with an extra prefix or suffix on their names by giving `configure' the -option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. - - Some packages pay attention to `--enable-FEATURE' options to -`configure', where FEATURE indicates an optional part of the package. -They may also pay attention to `--with-PACKAGE' options, where PACKAGE -is something like `gnu-as' or `x' (for the X Window System). The -`README' should mention any `--enable-' and `--with-' options that the -package recognizes. - - For packages that use the X Window System, `configure' can usually -find the X include and library files automatically, but if it doesn't, -you can use the `configure' options `--x-includes=DIR' and -`--x-libraries=DIR' to specify their locations. - - Some packages offer the ability to configure how verbose the -execution of `make' will be. For these packages, running `./configure ---enable-silent-rules' sets the default to minimal output, which can be -overridden with `make V=1'; while running `./configure ---disable-silent-rules' sets the default to verbose, which can be -overridden with `make V=0'. - -Particular systems -================== - - On HP-UX, the default C compiler is not ANSI C compatible. If GNU -CC is not installed, it is recommended to use the following options in -order to use an ANSI C compiler: - - ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" - -and if that doesn't work, install pre-built binaries of GCC for HP-UX. - - HP-UX `make' updates targets which have the same time stamps as -their prerequisites, which makes it generally unusable when shipped -generated files such as `configure' are involved. Use GNU `make' -instead. - - On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot -parse its `<wchar.h>' header file. The option `-nodtk' can be used as -a workaround. If GNU CC is not installed, it is therefore recommended -to try - - ./configure CC="cc" - -and if that doesn't work, try - - ./configure CC="cc -nodtk" - - On Solaris, don't put `/usr/ucb' early in your `PATH'. This -directory contains several dysfunctional programs; working variants of -these programs are available in `/usr/bin'. So, if you need `/usr/ucb' -in your `PATH', put it _after_ `/usr/bin'. - - On Haiku, software installed for all users goes in `/boot/common', -not `/usr/local'. It is recommended to use the following options: - - ./configure --prefix=/boot/common - -Specifying the System Type -========================== - - There may be some features `configure' cannot figure out -automatically, but needs to determine by the type of machine the package -will run on. Usually, assuming the package is built to be run on the -_same_ architectures, `configure' can figure that out, but if it prints -a message saying it cannot guess the machine type, give it the -`--build=TYPE' option. TYPE can either be a short name for the system -type, such as `sun4', or a canonical name which has the form: - - CPU-COMPANY-SYSTEM - -where SYSTEM can have one of these forms: - - OS - KERNEL-OS - - See the file `config.sub' for the possible values of each field. If -`config.sub' isn't included in this package, then this package doesn't -need to know the machine type. - - If you are _building_ compiler tools for cross-compiling, you should -use the option `--target=TYPE' to select the type of system they will -produce code for. - - If you want to _use_ a cross compiler, that generates code for a -platform different from the build platform, you should specify the -"host" platform (i.e., that on which the generated programs will -eventually be run) with `--host=TYPE'. - -Sharing Defaults -================ - - If you want to set default values for `configure' scripts to share, -you can create a site shell script called `config.site' that gives -default values for variables like `CC', `cache_file', and `prefix'. -`configure' looks for `PREFIX/share/config.site' if it exists, then -`PREFIX/etc/config.site' if it exists. Or, you can set the -`CONFIG_SITE' environment variable to the location of the site script. -A warning: not all `configure' scripts look for a site script. - -Defining Variables -================== - - Variables not defined in a site shell script can be set in the -environment passed to `configure'. However, some packages may run -configure again during the build, and the customized values of these -variables may be lost. In order to avoid this problem, you should set -them in the `configure' command line, using `VAR=value'. For example: - - ./configure CC=/usr/local2/bin/gcc - -causes the specified `gcc' to be used as the C compiler (unless it is -overridden in the site shell script). - -Unfortunately, this technique does not work for `CONFIG_SHELL' due to -an Autoconf limitation. Until the limitation is lifted, you can use -this workaround: - - CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash - -`configure' Invocation -====================== - - `configure' recognizes the following options to control how it -operates. - -`--help' -`-h' - Print a summary of all of the options to `configure', and exit. - -`--help=short' -`--help=recursive' - Print a summary of the options unique to this package's - `configure', and exit. The `short' variant lists options used - only in the top level, while the `recursive' variant lists options - also present in any nested packages. - -`--version' -`-V' - Print the version of Autoconf used to generate the `configure' - script, and exit. - -`--cache-file=FILE' - Enable the cache: use and save the results of the tests in FILE, - traditionally `config.cache'. FILE defaults to `/dev/null' to - disable caching. - -`--config-cache' -`-C' - Alias for `--cache-file=config.cache'. - -`--quiet' -`--silent' -`-q' - Do not print messages saying which checks are being made. To - suppress all normal output, redirect it to `/dev/null' (any error - messages will still be shown). - -`--srcdir=DIR' - Look for the package's source code in directory DIR. Usually - `configure' can determine that directory automatically. - -`--prefix=DIR' - Use DIR as the installation prefix. *note Installation Names:: - for more details, including other options available for fine-tuning - the installation locations. - -`--no-create' -`-n' - Run the configure checks, but stop before creating any output - files. - -`configure' also accepts some other, not widely useful, options. Run -`configure --help' for more details. diff --git a/src/third_party/pcre-8.38/LICENCE b/src/third_party/pcre-8.38/LICENCE deleted file mode 100644 index 9f6f98e477f..00000000000 --- a/src/third_party/pcre-8.38/LICENCE +++ /dev/null @@ -1,93 +0,0 @@ -PCRE LICENCE ------------- - -PCRE is a library of functions to support regular expressions whose syntax -and semantics are as close as possible to those of the Perl 5 language. - -Release 8 of PCRE is distributed under the terms of the "BSD" licence, as -specified below.

Note that this library (now called PCRE1) is now being -maintained for bug fixes only. New projects are advised to use the new PCRE2 -libraries. - - -Release 8.36 26-September-2014 ------------------------------- - -This is primarily a bug-fix release. However, in addition, the Unicode data -tables have been updated to Unicode 7.0.0. - - -Release 8.35 04-April-2014 --------------------------- - -There have been performance improvements for classes containing non-ASCII -characters and the "auto-possessification" feature has been extended. Other -minor improvements have been implemented and bugs fixed. There is a new callout -feature to enable applications to do detailed stack checks at compile time, to -avoid running out of stack for deeply nested parentheses. The JIT compiler has -been extended with experimental support for ARM-64, MIPS-64, and PPC-LE. - - -Release 8.34 15-December-2013 ------------------------------ - -As well as fixing the inevitable bugs, performance has been improved by -refactoring and extending the amount of "auto-possessification" that PCRE does. -Other notable changes: - -. Implemented PCRE_INFO_MATCH_EMPTY, which yields 1 if the pattern can match - an empty string. If it can, pcretest shows this in its information output. - -. A back reference to a named subpattern when there is more than one of the - same name now checks them in the order in which they appear in the pattern. - The first one that is set is used for the reference. Previously only the - first one was inspected. This change makes PCRE more compatible with Perl. - -. Unicode character properties were updated from Unicode 6.3.0. - -. The character VT has been added to the set of characters that match \s and - are generally treated as white space, following this same change in Perl - 5.18. There is now no difference between "Perl space" and "POSIX space". - -. Perl has changed its handling of \8 and \9. If there is no previously - encountered capturing group of those numbers, they are treated as the - literal characters 8 and 9 instead of a binary zero followed by the - literals. PCRE now does the same. - -. Following Perl, added \o{} to specify codepoints in octal, making it - possible to specify values greater than 0777 and also making them - unambiguous. - -. In UCP mode, \s was not matching two of the characters that Perl matches, - namely NEL (U+0085) and MONGOLIAN VOWEL SEPARATOR (U+180E), though they - were matched by \h. - -. Add JIT support for the 64 bit TileGX architecture. - -. Upgraded the handling of the POSIX classes [:graph:], [:print:], and - [:punct:] when PCRE_UCP is set so as to include the same characters as Perl - does in Unicode mode. - -. Perl no longer allows group names to start with digits, so I have made this - change also in PCRE. - -. Added support for [[:<:]] and [[:>:]] as used in the BSD POSIX library to - mean "start of word" and "end of word", respectively, as a transition aid. - - -Release 8.33 28-May-2013 --------------------------- - -A number of bugs are fixed, and some performance improvements have been made. -There are also some new features, of which these are the most important: - -. The behaviour of the backtracking verbs has been rationalized and - documented in more detail. - -. JIT now supports callouts and all of the backtracking verbs. - -. Unicode validation has been updated in the light of Unicode Corrigendum #9, - which points out that "non characters" are not "characters that may not - appear in Unicode strings" but rather "characters that are reserved for - internal use and have only local meaning". - -. (*LIMIT_MATCH=d) and (*LIMIT_RECURSION=d) have been added so that the - creator of a pattern can specify lower (but not higher) limits for the - matching process. - -. The PCRE_NEVER_UTF option is available to prevent pattern-writers from using - the (*UTF) feature, as this could be a security issue. - - -Release 8.32 30-November-2012 ------------------------------ - -This release fixes a number of bugs, but also has some new features. These are -the highlights: - -. There is now support for 32-bit character strings and UTF-32. Like the - 16-bit support, this is done by compiling a separate 32-bit library. - -. \X now matches a Unicode extended grapheme cluster. - -. Case-independent matching of Unicode characters that have more than one - "other case" now makes all three (or more) characters equivalent. This - applies, for example, to Greek Sigma, which has two lowercase versions. - -. Unicode character properties are updated to Unicode 6.2.0. - -. The EBCDIC support, which had decayed, has had a spring clean. - -. A number of JIT optimizations have been added, which give faster JIT - execution speed. In addition, a new direct interface to JIT execution is - available. This bypasses some of the sanity checks of pcre_exec() to give a - noticeable speed-up. - -. A number of issues in pcregrep have been fixed, making it more compatible - with GNU grep. In particular, --exclude and --include (and variants) apply - to all files now, not just those obtained from scanning a directory - recursively. In Windows environments, the default action for directories is - now "skip" instead of "read" (which provokes an error). - -. If the --only-matching (-o) option in pcregrep is specified multiple - times, each one causes appropriate output. For example, -o1 -o2 outputs the - substrings matched by the 1st and 2nd capturing parentheses. A separating - string can be specified by --om-separator (default empty). - -. When PCRE is built via Autotools using a version of gcc that has the - "visibility" feature, it is used to hide internal library functions that are - not part of the public API. - - -Release 8.31 06-July-2012 -------------------------- - -This is mainly a bug-fixing release, with a small number of developments: - -. The JIT compiler now supports partial matching and the (*MARK) and - (*COMMIT) verbs. - -. PCRE_INFO_MAXLOOKBEHIND can be used to find the longest lookbehind in a - pattern. - -. There should be a performance improvement when using the heap instead of the - stack for recursion. - -. pcregrep can now be linked with libedit as an alternative to libreadline. - -. pcregrep now has a --file-list option where the list of files to scan is - given as a file. - -. pcregrep now recognizes binary files and there are related options. - -. The Unicode tables have been updated to 6.1.0. - -As always, the full list of changes is in the ChangeLog file. - - -Release 8.30 04-February-2012 ------------------------------ - -Release 8.30 introduces a major new feature: support for 16-bit character -strings, compiled as a separate library. There are a few changes to the -8-bit library, in addition to some bug fixes. - -. The pcre_info() function, which has been obsolete for over 10 years, has - been removed. - -. When a compiled pattern was saved to a file and later reloaded on a host - with different endianness, PCRE used automatically to swap the bytes in some - of the data fields. With the advent of the 16-bit library, where more of this - swapping is needed, it is no longer done automatically. Instead, the bad - endianness is detected and a specific error is given. The user can then call - a new function called pcre_pattern_to_host_byte_order() (or an equivalent - 16-bit function) to do the swap. - -. In UTF-8 mode, the values 0xd800 to 0xdfff are not legal Unicode - code points and are now faulted. (They are the so-called "surrogates" - that are reserved for coding high values in UTF-16.) - - -Release 8.21 12-Dec-2011 ------------------------- - -This is almost entirely a bug-fix release. The only new feature is the ability -to obtain the size of the memory used by the JIT compiler. - - -Release 8.20 21-Oct-2011 ------------------------- - -The main change in this release is the inclusion of Zoltan Herczeg's -just-in-time compiler support, which can be accessed by building PCRE with ---enable-jit. Large performance benefits can be had in many situations. 8.20 -also fixes an unfortunate bug that was introduced in 8.13 as well as tidying up -a number of infelicities and differences from Perl. - - -Release 8.13 16-Aug-2011 ------------------------- - -This is mainly a bug-fix release. There has been a lot of internal refactoring. -The Unicode tables have been updated. The only new feature in the library is -the passing of *MARK information to callouts. Some additions have been made to -pcretest to make testing easier and more comprehensive. There is a new option -for pcregrep to adjust its internal buffer size. - - -Release 8.12 15-Jan-2011 ------------------------- - -This release fixes some bugs in pcregrep, one of which caused the tests to fail -on 64-bit big-endian systems. There are no changes to the code of the library. - - -Release 8.11 10-Dec-2010 ------------------------- - -A number of bugs in the library and in pcregrep have been fixed. As always, see -ChangeLog for details. The following are the non-bug-fix changes: - -. Added --match-limit and --recursion-limit to pcregrep. - -. Added an optional parentheses number to the -o and --only-matching options - of pcregrep. - -. Changed the way PCRE_PARTIAL_HARD affects the matching of $, \z, \Z, \b, and - \B. - -. Added PCRE_ERROR_SHORTUTF8 to make it possible to distinguish between a - bad UTF-8 sequence and one that is incomplete when using PCRE_PARTIAL_HARD. - -. Recognize (*NO_START_OPT) at the start of a pattern to set the PCRE_NO_ - START_OPTIMIZE option, which is now allowed at compile time - - -Release 8.10 25-Jun-2010 ------------------------- - -There are two major additions: support for (*MARK) and friends, and the option -PCRE_UCP, which changes the behaviour of \b, \d, \s, and \w (and their -opposites) so that they make use of Unicode properties. There are also a number -of lesser new features, and several bugs have been fixed. A new option, ---line-buffered, has been added to pcregrep, for use when it is connected to -pipes. - - -Release 8.02 19-Mar-2010 ------------------------- - -Another bug-fix release. - - -Release 8.01 19-Jan-2010 ------------------------- - -This is a bug-fix release. Several bugs in the code itself and some bugs and -infelicities in the build system have been fixed. - - -Release 8.00 19-Oct-09 ----------------------- - -Bugs have been fixed in the library and in pcregrep. There are also some -enhancements. Restrictions on patterns used for partial matching have been -removed, extra information is given for partial matches, the partial matching -process has been improved, and an option to make a partial match override a -full match is available. The "study" process has been enhanced by finding a -lower bound matching length. Groups with duplicate numbers may now have -duplicated names without the use of PCRE_DUPNAMES. However, they may not have -different names. The documentation has been revised to reflect these changes. -The version number has been expanded to 3 digits as it is clear that the rate -of change is not slowing down. - - -Release 7.9 11-Apr-09 ---------------------- - -Mostly bugfixes and tidies with just a couple of minor functional additions. - - -Release 7.8 05-Sep-08 ---------------------- - -More bug fixes, plus a performance improvement in Unicode character property -lookup. - - -Release 7.7 07-May-08 ---------------------- - -This is once again mainly a bug-fix release, but there are a couple of new -features. - - -Release 7.6 28-Jan-08 ---------------------- - -The main reason for having this release so soon after 7.5 is because it fixes a -potential buffer overflow problem in pcre_compile() when run in UTF-8 mode. In -addition, the CMake configuration files have been brought up to date. - - -Release 7.5 10-Jan-08 ---------------------- - -This is mainly a bug-fix release. However the ability to link pcregrep with -libz or libbz2 and the ability to link pcretest with libreadline have been -added. Also the --line-offsets and --file-offsets options were added to -pcregrep. - - -Release 7.4 21-Sep-07 ---------------------- - -The only change of specification is the addition of options to control whether -\R matches any Unicode line ending (the default) or just CR, LF, and CRLF. -Otherwise, the changes are bug fixes and a refactoring to reduce the number of -relocations needed in a shared library. There have also been some documentation -updates, in particular, some more information about using CMake to build PCRE -has been added to the NON-UNIX-USE file. - - -Release 7.3 28-Aug-07 ---------------------- - -Most changes are bug fixes. Some that are not: - -1. There is some support for Perl 5.10's experimental "backtracking control - verbs" such as (*PRUNE). - -2. UTF-8 checking is now as per RFC 3629 instead of RFC 2279; this is more - restrictive in the strings it accepts. - -3. Checking for potential integer overflow has been made more dynamic, and as a - consequence there is no longer a hard limit on the size of a subpattern that - has a limited repeat count. - -4. When CRLF is a valid line-ending sequence, pcre_exec() and pcre_dfa_exec() - no longer advance by two characters instead of one when an unanchored match - fails at CRLF if there are explicit CR or LF matches within the pattern. - This gets rid of some anomalous effects that previously occurred. - -5. Some PCRE-specific settings for varying the newline options at the start of - a pattern have been added. - - -Release 7.2 19-Jun-07 ---------------------- - -WARNING: saved patterns that were compiled by earlier versions of PCRE must be -recompiled for use with 7.2 (necessitated by the addition of \K, \h, \H, \v, -and \V). - -Correction to the notes for 7.1: the note about shared libraries for Windows is -wrong. Previously, three libraries were built, but each could function -independently. For example, the pcreposix library also included all the -functions from the basic pcre library. The change is that the three libraries -are no longer independent. They are like the Unix libraries. To use the -pcreposix functions, for example, you need to link with both the pcreposix and -the basic pcre library. - -Some more features from Perl 5.10 have been added: - - (?-n) and (?+n) relative references for recursion and subroutines. - - (?(-n) and (?(+n) relative references as conditions. - - \k{name} and \g{name} are synonyms for \k<name>. - - \K to reset the start of the matched string; for example, (foo)\Kbar - matches bar preceded by foo, but only sets bar as the matched string. - - (?| introduces a group where the capturing parentheses in each alternative - start from the same number; for example, (?|(abc)|(xyz)) sets capturing - parentheses number 1 in both cases. - - \h, \H, \v, \V match horizontal and vertical whitespace, respectively. - - -Release 7.1 24-Apr-07 ---------------------- - -There is only one new feature in this release: a linebreak setting of -PCRE_NEWLINE_ANYCRLF. It is a cut-down version of PCRE_NEWLINE_ANY, which -recognizes only CRLF, CR, and LF as linebreaks. - -A few bugs are fixed (see ChangeLog for details), but the major change is a -complete re-implementation of the build system. This now has full Autotools -support and so is now "standard" in some sense. It should help with compiling -PCRE in a wide variety of environments. - -NOTE: when building shared libraries for Windows, three dlls are now built, -called libpcre, libpcreposix, and libpcrecpp. Previously, everything was -included in a single dll. - -Another important change is that the dftables auxiliary program is no longer -compiled and run at "make" time by default. Instead, a default set of character -tables (assuming ASCII coding) is used. If you want to use dftables to generate -the character tables as previously, add --enable-rebuild-chartables to the -"configure" command. You must do this if you are compiling PCRE to run on a -system that uses EBCDIC code. - -There is a discussion about character tables in the README file. The default is -not to use dftables so that that there is no problem when cross-compiling. - - -Release 7.0 19-Dec-06 ---------------------- - -This release has a new major number because there have been some internal -upheavals to facilitate the addition of new optimizations and other facilities, -and to make subsequent maintenance and extension easier. Compilation is likely -to be a bit slower, but there should be no major effect on runtime performance. -Previously compiled patterns are NOT upwards compatible with this release. If -you have saved compiled patterns from a previous release, you will have to -re-compile them. Important changes that are visible to users are: - -1. The Unicode property tables have been updated to Unicode 5.0.0, which adds - some more scripts. - -2. The option PCRE_NEWLINE_ANY causes PCRE to recognize any Unicode newline - sequence as a newline. - -3. The \R escape matches a single Unicode newline sequence as a single unit. - -4. New features that will appear in Perl 5.10 are now in PCRE. These include - alternative Perl syntax for named parentheses, and Perl syntax for - recursion. - -5. The C++ wrapper interface has been extended by the addition of a - QuoteMeta function and the ability to allow copy construction and - assignment. - -For a complete list of changes, see the ChangeLog file. - - -Release 6.7 04-Jul-06 ---------------------- - -The main additions to this release are the ability to use the same name for -multiple sets of parentheses, and support for CRLF line endings in both the -library and pcregrep (and in pcretest for testing). - -Thanks to Ian Taylor, the stack usage for many kinds of pattern has been -significantly reduced for certain subject strings. - - -Release 6.5 01-Feb-06 ---------------------- - -Important changes in this release: - -1. A number of new features have been added to pcregrep. - -2. The Unicode property tables have been updated to Unicode 4.1.0, and the - supported properties have been extended with script names such as "Arabic", - and the derived properties "Any" and "L&". This has necessitated a change to - the interal format of compiled patterns. Any saved compiled patterns that - use \p or \P must be recompiled. - -3. The specification of recursion in patterns has been changed so that all - recursive subpatterns are automatically treated as atomic groups. Thus, for - example, (?R) is treated as if it were (?>(?R)). This is necessary because - otherwise there are situations where recursion does not work. - -See the ChangeLog for a complete list of changes, which include a number of bug -fixes and tidies. - - -Release 6.0 07-Jun-05 ---------------------- - -The release number has been increased to 6.0 because of the addition of several -major new pieces of functionality. - -A new function, pcre_dfa_exec(), which implements pattern matching using a DFA -algorithm, has been added. This has a number of advantages for certain cases, -though it does run more slowly, and lacks the ability to capture substrings. On -the other hand, it does find all matches, not just the first, and it works -better for partial matching. The pcrematching man page discusses the -differences. - -The pcretest program has been enhanced so that it can make use of the new -pcre_dfa_exec() matching function and the extra features it provides. - -The distribution now includes a C++ wrapper library. This is built -automatically if a C++ compiler is found. The pcrecpp man page discusses this -interface. - -The code itself has been re-organized into many more files, one for each -function, so it no longer requires everything to be linked in when static -linkage is used. As a consequence, some internal functions have had to have -their names exposed. These functions all have names starting with _pcre_. They -are undocumented, and are not intended for use by outside callers. - -The pcregrep program has been enhanced with new functionality such as -multiline-matching and options for output more matching context. See the -ChangeLog for a complete list of changes to the library and the utility -programs. - - -Release 5.0 13-Sep-04 ---------------------- - -The licence under which PCRE is released has been changed to the more -conventional "BSD" licence. - -In the code, some bugs have been fixed, and there are also some major changes -in this release (which is why I've increased the number to 5.0). Some changes -are internal rearrangements, and some provide a number of new facilities. The -new features are: - -1. There's an "automatic callout" feature that inserts callouts before every - item in the regex, and there's a new callout field that gives the position - in the pattern - useful for debugging and tracing. - -2. The extra_data structure can now be used to pass in a set of character - tables at exec time. This is useful if compiled regex are saved and re-used - at a later time when the tables may not be at the same address. If the - default internal tables are used, the pointer saved with the compiled - pattern is now set to NULL, which means that you don't need to do anything - special unless you are using custom tables. - -3. It is possible, with some restrictions on the content of the regex, to - request "partial" matching. A special return code is given if all of the - subject string matched part of the regex. This could be useful for testing - an input field as it is being typed. - -4. There is now some optional support for Unicode character properties, which - means that the patterns items such as \p{Lu} and \X can now be used. Only - the general category properties are supported. If PCRE is compiled with this - support, an additional 90K data structure is include, which increases the - size of the library dramatically. - -5. There is support for saving compiled patterns and re-using them later. - -6. There is support for running regular expressions that were compiled on a - different host with the opposite endianness. - -7. The pcretest program has been extended to accommodate the new features. - -The main internal rearrangement is that sequences of literal characters are no -longer handled as strings. Instead, each character is handled on its own. This -makes some UTF-8 handling easier, and makes the support of partial matching -possible. Compiled patterns containing long literal strings will be larger as a -result of this change; I hope that performance will not be much affected. - - -Release 4.5 01-Dec-03 ---------------------- - -Again mainly a bug-fix and tidying release, with only a couple of new features: - -1. It's possible now to compile PCRE so that it does not use recursive -function calls when matching. Instead it gets memory from the heap. This slows -things down, but may be necessary on systems with limited stacks. - -2. UTF-8 string checking has been tightened to reject overlong sequences and to -check that a starting offset points to the start of a character. Failure of the -latter returns a new error code: PCRE_ERROR_BADUTF8_OFFSET. - -3. PCRE can now be compiled for systems that use EBCDIC code. - - -Release 4.4 21-Aug-03 ---------------------- - -This is mainly a bug-fix and tidying release. The only new feature is that PCRE -checks UTF-8 strings for validity by default. There is an option to suppress -this, just in case anybody wants that teeny extra bit of performance. - - -Releases 4.1 - 4.3 ------------------- - -Sorry, I forgot about updating the NEWS file for these releases. Please take a -look at ChangeLog. - - -Release 4.0 17-Feb-03 ---------------------- - -There have been a lot of changes for the 4.0 release, adding additional -functionality and mending bugs. Below is a list of the highlights of the new -functionality. For full details of these features, please consult the -documentation. For a complete list of changes, see the ChangeLog file. - -1. Support for Perl's \Q...\E escapes. - -2. "Possessive quantifiers" ?+, *+, ++, and {,}+ which come from Sun's Java -package. They provide some syntactic sugar for simple cases of "atomic -grouping". - -3. Support for the \G assertion. It is true when the current matching position -is at the start point of the match. - -4. A new feature that provides some of the functionality that Perl provides -with (?{...}). The facility is termed a "callout". The way it is done in PCRE -is for the caller to provide an optional function, by setting pcre_callout to -its entry point. To get the function called, the regex must include (?C) at -appropriate points. - -5. Support for recursive calls to individual subpatterns. This makes it really -easy to get totally confused. - -6. Support for named subpatterns. The Python syntax (?P<name>...) is used to -name a group. - -7. Several extensions to UTF-8 support; it is now fairly complete. There is an -option for pcregrep to make it operate in UTF-8 mode. - -8. The single man page has been split into a number of separate man pages. -These also give rise to individual HTML pages which are put in a separate -directory. There is an index.html page that lists them all. Some hyperlinking -between the pages has been installed. - - -Release 3.5 15-Aug-01 ---------------------- - -1. The configuring system has been upgraded to use later versions of autoconf -and libtool. By default it builds both a shared and a static library if the OS -supports it. You can use --disable-shared or --disable-static on the configure -command if you want only one of them. - -2. The pcretest utility is now installed along with pcregrep because it is -useful for users (to test regexs) and by doing this, it automatically gets -relinked by libtool. The documentation has been turned into a man page, so -there are now .1, .txt, and .html versions in /doc. - -3. Upgrades to pcregrep: - (i) Added long-form option names like gnu grep. - (ii) Added --help to list all options with an explanatory phrase. - (iii) Added -r, --recursive to recurse into sub-directories. - (iv) Added -f, --file to read patterns from a file. - -4. Added --enable-newline-is-cr and --enable-newline-is-lf to the configure -script, to force use of CR or LF instead of \n in the source. On non-Unix -systems, the value can be set in config.h. - -5. The limit of 200 on non-capturing parentheses is a _nesting_ limit, not an -absolute limit. Changed the text of the error message to make this clear, and -likewise updated the man page. - -6. The limit of 99 on the number of capturing subpatterns has been removed. -The new limit is 65535, which I hope will not be a "real" limit. - - -Release 3.3 01-Aug-00 ---------------------- - -There is some support for UTF-8 character strings. This is incomplete and -experimental. The documentation describes what is and what is not implemented. -Otherwise, this is just a bug-fixing release. - - -Release 3.0 01-Feb-00 ---------------------- - -1. A "configure" script is now used to configure PCRE for Unix systems. It -builds a Makefile, a config.h file, and the pcre-config script. - -2. PCRE is built as a shared library by default. - -3. There is support for POSIX classes such as [:alpha:]. - -5. There is an experimental recursion feature. - ----------------------------------------------------------------------------- - IMPORTANT FOR THOSE UPGRADING FROM VERSIONS BEFORE 2.00 - -Please note that there has been a change in the API such that a larger -ovector is required at matching time, to provide some additional workspace. -The new man page has details. This change was necessary in order to support -some of the new functionality in Perl 5.005. - - IMPORTANT FOR THOSE UPGRADING FROM VERSION 2.00 - -Another (I hope this is the last!) change has been made to the API for the -pcre_compile() function. An additional argument has been added to make it -possible to pass over a pointer to character tables built in the current -locale by pcre_maketables(). To use the default tables, this new argument -should be passed as NULL. - - IMPORTANT FOR THOSE UPGRADING FROM VERSION 2.05 - -Yet another (and again I hope this really is the last) change has been made -to the API for the pcre_exec() function. An additional argument has been -added to make it possible to start the match other than at the start of the -subject string. This is important if there are lookbehinds. The new man -page has the details, but you just want to convert existing programs, all -you need to do is to stick in a new fifth argument to pcre_exec(), with a -value of zero. For example, change - - pcre_exec(pattern, extra, subject, length, options, ovec, ovecsize) -to - pcre_exec(pattern, extra, subject, length, 0, options, ovec, ovecsize) - -**** diff --git a/src/third_party/pcre-8.38/NON-AUTOTOOLS-BUILD b/src/third_party/pcre-8.38/NON-AUTOTOOLS-BUILD deleted file mode 100644 index 3910059106b..00000000000 --- a/src/third_party/pcre-8.38/NON-AUTOTOOLS-BUILD +++ /dev/null @@ -1,772 +0,0 @@ -Building PCRE without using autotools -------------------------------------- - -NOTE: This document relates to PCRE releases that use the original API, with -library names libpcre, libpcre16, and libpcre32.

The usual EBCDIC newline character is 21 (0x15, - NL), though in some cases it may be 37 (0x25). - - When you compile any of the PCRE modules, you must specify -DHAVE_CONFIG_H - to your compiler so that config.h is included in the sources. - - An alternative approach is not to edit config.h, but to use -D on the - compiler command line to make any changes that you need to the - configuration options. In this case -DHAVE_CONFIG_H must not be set. - - NOTE: There have been occasions when the way in which certain parameters - in config.h are used has changed between releases. (In the configure/make - world, this is handled automatically.) When upgrading to a new release, - you are strongly advised to review config.h.generic before re-using what - you had previously. - - (2) Copy or rename the file pcre.h.generic as pcre.h. - - (3) EITHER: - Copy or rename file pcre_chartables.c.dist as pcre_chartables.c. - - OR: - Compile dftables.c as a stand-alone program (using -DHAVE_CONFIG_H if - you have set up config.h), and then run it with the single argument - "pcre_chartables.c". This generates a set of standard character tables - and writes them to that file. The tables are generated using the default - C locale for your system. If you want to use a locale that is specified - by LC_xxx environment variables, add the -L option to the dftables - command. You must use this method if you are building on a system that - uses EBCDIC code. - - The tables in pcre_chartables.c are defaults. The caller of PCRE can - specify alternative tables at run time. - - (4) Ensure that you have the following header files: - - pcre_internal.h - ucp.h - - (5) For an 8-bit library, compile the following source files, setting - -DHAVE_CONFIG_H as a compiler option if you have set up config.h with your - configuration, or else use other -D settings to change the configuration - as required. - - pcre_byte_order.c - pcre_chartables.c - pcre_compile.c - pcre_config.c - pcre_dfa_exec.c - pcre_exec.c - pcre_fullinfo.c - pcre_get.c - pcre_globals.c - pcre_jit_compile.c - pcre_maketables.c - pcre_newline.c - pcre_ord2utf8.c - pcre_refcount.c - pcre_string_utils.c - pcre_study.c - pcre_tables.c - pcre_ucd.c - pcre_valid_utf8.c - pcre_version.c - pcre_xclass.c - - Make sure that you include -I. in the compiler command (or equivalent for - an unusual compiler) so that all included PCRE header files are first - sought in the current directory. Otherwise you run the risk of picking up - a previously-installed file from somewhere else. - - Note that you must still compile pcre_jit_compile.c, even if you have not - defined SUPPORT_JIT in config.h, because when JIT support is not - configured, dummy functions are compiled. When JIT support IS configured, - pcre_jit_compile.c #includes sources from the sljit subdirectory, where - there should be 16 files, all of whose names begin with "sljit". - - (6) Now link all the compiled code into an object library in whichever form - your system keeps such libraries. This is the basic PCRE C 8-bit library. - If your system has static and shared libraries, you may have to do this - once for each type. - - (7) If you want to build a 16-bit library (as well as, or instead of the 8-bit - or 32-bit libraries) repeat steps 5-6 with the following files: - - pcre16_byte_order.c - pcre16_chartables.c - pcre16_compile.c - pcre16_config.c - pcre16_dfa_exec.c - pcre16_exec.c - pcre16_fullinfo.c - pcre16_get.c - pcre16_globals.c - pcre16_jit_compile.c - pcre16_maketables.c - pcre16_newline.c - pcre16_ord2utf16.c - pcre16_refcount.c - pcre16_string_utils.c - pcre16_study.c - pcre16_tables.c - pcre16_ucd.c - pcre16_utf16_utils.c - pcre16_valid_utf16.c - pcre16_version.c - pcre16_xclass.c - - (8) If you want to build a 32-bit library (as well as, or instead of the 8-bit - or 16-bit libraries) repeat steps 5-6 with the following files: - - pcre32_byte_order.c - pcre32_chartables.c - pcre32_compile.c - pcre32_config.c - pcre32_dfa_exec.c - pcre32_exec.c - pcre32_fullinfo.c - pcre32_get.c - pcre32_globals.c - pcre32_jit_compile.c - pcre32_maketables.c - pcre32_newline.c - pcre32_ord2utf32.c - pcre32_refcount.c - pcre32_string_utils.c - pcre32_study.c - pcre32_tables.c - pcre32_ucd.c - pcre32_utf32_utils.c - pcre32_valid_utf32.c - pcre32_version.c - pcre32_xclass.c - - (9) If you want to build the POSIX wrapper functions (which apply only to the - 8-bit library), ensure that you have the pcreposix.h file and then compile - pcreposix.c (remembering -DHAVE_CONFIG_H if necessary). Link the result - (on its own) as the pcreposix library. - -(10) The pcretest program can be linked with any combination of the 8-bit, - 16-bit and 32-bit libraries (depending on what you selected in config.h). - Compile pcretest.c and pcre_printint.c (again, don't forget - -DHAVE_CONFIG_H) and link them together with the appropriate library/ies. - If you compiled an 8-bit library, pcretest also needs the pcreposix - wrapper library unless you compiled it with -DNOPOSIX. - -(11) Run pcretest on the testinput files in the testdata directory, and check - that the output matches the corresponding testoutput files. There are - comments about what each test does in the section entitled "Testing PCRE" - in the README file. If you compiled more than one of the 8-bit, 16-bit and - 32-bit libraries, you need to run pcretest with the -16 option to do - 16-bit tests and with the -32 option to do 32-bit tests. - - Some tests are relevant only when certain build-time options are selected. - For example, test 4 is for UTF-8/UTF-16/UTF-32 support, and will not run - if you have built PCRE without it. See the comments at the start of each - testinput file. If you have a suitable Unix-like shell, the RunTest script - will run the appropriate tests for you. The command "RunTest list" will - output a list of all the tests. - - Note that the supplied files are in Unix format, with just LF characters - as line terminators. You may need to edit them to change this if your - system uses a different convention. If you are using Windows, you probably - should use the wintestinput3 file instead of testinput3 (and the - corresponding output file). This is a locale test; wintestinput3 sets the - locale to "french" rather than "fr_FR", and there some minor output - differences. - -(12) If you have built PCRE with SUPPORT_JIT, the JIT features will be tested - by the testdata files. However, you might also like to build and run - the freestanding JIT test program, pcre_jit_test.c. - -(13) If you want to use the pcregrep command, compile and link pcregrep.c; it - uses only the basic 8-bit PCRE library (it does not need the pcreposix - library). - - -THE C++ WRAPPER FUNCTIONS - -The PCRE distribution also contains some C++ wrapper functions and tests, -applicable to the 8-bit library, which were contributed by Google Inc. On a -system that can use "configure" and "make", the functions are automatically -built into a library called pcrecpp. It should be straightforward to compile -the .cc files manually on other systems. The files called xxx_unittest.cc are -test programs for each of the corresponding xxx.cc files. - - -BUILDING FOR VIRTUAL PASCAL - -A script for building PCRE using Borland's C++ compiler for use with VPASCAL -was contributed by Alexander Tokarev. Stefan Weber updated the script and added -additional files. The following files in the distribution are for building PCRE -for use with VP/Borland: makevp_c.txt, makevp_l.txt, makevp.bat, pcregexp.pas. - - -STACK SIZE IN WINDOWS ENVIRONMENTS - -The default processor stack size of 1Mb in some Windows environments is too -small for matching patterns that need much recursion. In particular, test 2 may -fail because of this. Normally, running out of stack causes a crash, but there -have been cases where the test program has just died silently. See your linker -documentation for how to increase stack size if you experience problems. The -Linux default of 8Mb is a reasonable choice for the stack, though even that can -be too small for some pattern/subject combinations. - -PCRE has a compile configuration option to disable the use of stack for -recursion so that heap is used instead. However, pattern matching is -significantly slower when this is done. There is more about stack usage in the -"pcrestack" documentation. - - -LINKING PROGRAMS IN WINDOWS ENVIRONMENTS - -If you want to statically link a program against a PCRE library in the form of -a non-dll .a file, you must define PCRE_STATIC before including pcre.h or -pcrecpp.h, otherwise the pcre_malloc() and pcre_free() exported functions will -be declared __declspec(dllimport), with unwanted results. - - -CALLING CONVENTIONS IN WINDOWS ENVIRONMENTS - -It is possible to compile programs to use different calling conventions using -MSVC. Search the web for "calling conventions" for more information. To make it -easier to change the calling convention for the exported functions in the -PCRE library, the macro PCRE_CALL_CONVENTION is present in all the external -definitions. It can be set externally when compiling (e.g. in CFLAGS). If it is -not set, it defaults to empty; the default calling convention is then used -(which is what is wanted most of the time). - - -COMMENTS ABOUT WIN32 BUILDS (see also "BUILDING PCRE ON WINDOWS WITH CMAKE") - -There are two ways of building PCRE using the "configure, make, make install" -paradigm on Windows systems: using MinGW or using Cygwin. These are not at all -the same thing; they are completely different from each other. There is also -support for building using CMake, which some users find a more straightforward -way of building PCRE under Windows. - -The MinGW home page (http://www.mingw.org/) says this: - - MinGW: A collection of freely available and freely distributable Windows - specific header files and import libraries combined with GNU toolsets that - allow one to produce native Windows programs that do not rely on any - 3rd-party C runtime DLLs. - -The Cygwin home page (http://www.cygwin.com/) says this: - - Cygwin is a Linux-like environment for Windows. It consists of two parts: - - . A DLL (cygwin1.dll) which acts as a Linux API emulation layer providing - substantial Linux API functionality - - . A collection of tools which provide Linux look and feel. - - The Cygwin DLL currently works with all recent, commercially released x86 32 - bit and 64 bit versions of Windows, with the exception of Windows CE. - -On both MinGW and Cygwin, PCRE should build correctly using: - - ./configure && make && make install - -This should create two libraries called libpcre and libpcreposix, and, if you -have enabled building the C++ wrapper, a third one called libpcrecpp. These are -independent libraries: when you link with libpcreposix or libpcrecpp you must -also link with libpcre, which contains the basic functions. (Some earlier -releases of PCRE included the basic libpcre functions in libpcreposix. This no -longer happens.) - -A user submitted a special-purpose patch that makes it easy to create -"pcre.dll" under mingw32 using the "msys" environment. It provides "pcre.dll" -as a special target. If you use this target, no other files are built, and in -particular, the pcretest and pcregrep programs are not built. An example of how -this might be used is: - - ./configure --enable-utf --disable-cpp CFLAGS="-03 -s"; make pcre.dll - -Using Cygwin's compiler generates libraries and executables that depend on -cygwin1.dll. If a library that is generated this way is distributed, -cygwin1.dll has to be distributed as well. Since cygwin1.dll is under the GPL -licence, this forces not only PCRE to be under the GPL, but also the entire -application. A distributor who wants to keep their own code proprietary must -purchase an appropriate Cygwin licence. - -MinGW has no such restrictions. The MinGW compiler generates a library or -executable that can run standalone on Windows without any third party dll or -licensing issues. - -But there is more complication: - -If a Cygwin user uses the -mno-cygwin Cygwin gcc flag, what that really does is -to tell Cygwin's gcc to use the MinGW gcc. Cygwin's gcc is only acting as a -front end to MinGW's gcc (if you install Cygwin's gcc, you get both Cygwin's -gcc and MinGW's gcc). So, a user can: - -. Build native binaries by using MinGW or by getting Cygwin and using - -mno-cygwin. - -. Build binaries that depend on cygwin1.dll by using Cygwin with the normal - compiler flags. - -The test files that are supplied with PCRE are in UNIX format, with LF -characters as line terminators. Unless your PCRE library uses a default newline -option that includes LF as a valid newline, it may be necessary to change the -line terminators in the test files to get some of the tests to work. - - -BUILDING PCRE ON WINDOWS WITH CMAKE - -CMake is an alternative configuration facility that can be used instead of -"configure". CMake creates project files (make files, solution files, etc.) -tailored to numerous development environments, including Visual Studio, -Borland, Msys, MinGW, NMake, and Unix. If possible, use short paths with no -spaces in the names for your CMake installation and your PCRE source and build -directories. - -The following instructions were contributed by a PCRE user. If they are not -followed exactly, errors may occur. In the event that errors do occur, it is -recommended that you delete the CMake cache before attempting to repeat the -CMake build process. In the CMake GUI, the cache can be deleted by selecting -"File > Delete Cache". - -1. Install the latest CMake version available from http://www.cmake.org/, and - ensure that cmake\bin is on your path. - -2. Unzip (retaining folder structure) the PCRE source tree into a source - directory such as C:\pcre. You should ensure your local date and time - is not earlier than the file dates in your source dir if the release is - very new. - -3. Create a new, empty build directory, preferably a subdirectory of the - source dir. For example, C:\pcre\pcre-xx\build. - -4. Run cmake-gui from the Shell envirornment of your build tool, for example, - Msys for Msys/MinGW or Visual Studio Command Prompt for VC/VC++. Do not try - to start Cmake from the Windows Start menu, as this can lead to errors. - -5. Enter C:\pcre\pcre-xx and C:\pcre\pcre-xx\build for the source and build - directories, respectively. - -6. Hit the "Configure" button. - -7. Select the particular IDE / build tool that you are using (Visual - Studio, MSYS makefiles, MinGW makefiles, etc.) - -8. The GUI will then list several configuration options. This is where - you can enable UTF-8 support or other PCRE optional features. - -9. Hit "Configure" again. The adjacent "Generate" button should now be - active. - -10. Hit "Generate". - -11. The build directory should now contain a usable build system, be it a - solution file for Visual Studio, makefiles for MinGW, etc. Exit from - cmake-gui and use the generated build system with your compiler or IDE. - E.g., for MinGW you can run "make", or for Visual Studio, open the PCRE - solution, select the desired configuration (Debug, or Release, etc.) and - build the ALL_BUILD project. - -12. If during configuration with cmake-gui you've elected to build the test - programs, you can execute them by building the test project. E.g., for - MinGW: "make test"; for Visual Studio build the RUN_TESTS project. The - most recent build configuration is targeted by the tests. A summary of - test results is presented. Complete test output is subsequently - available for review in Testing\Temporary under your build dir. - - -USE OF RELATIVE PATHS WITH CMAKE ON WINDOWS - -A PCRE user comments as follows: I thought that others may want to know the -current state of CMAKE_USE_RELATIVE_PATHS support on Windows. Here it is: - --- AdditionalIncludeDirectories is only partially modified (only the - first path - see below) --- Only some of the contained file paths are modified - shown below for - pcre.vcproj --- It properly modifies - -I am sure CMake people can fix that if they want to. Until then one will -need to replace existing absolute paths in project files with relative -paths manually (e.g. from VS) - relative to project file location. I did -just that before being told to try CMAKE_USE_RELATIVE_PATHS. Not a big -deal. - -AdditionalIncludeDirectories="E:\builds\pcre\build;E:\builds\pcre\pcre-7.5;" -AdditionalIncludeDirectories=".;E:\builds\pcre\pcre-7.5;" - -RelativePath="pcre.h" -RelativePath="pcre_chartables.c" -RelativePath="pcre_chartables.c.rule" - - -TESTING WITH RUNTEST.BAT - -If configured with CMake, building the test project ("make test" or building -ALL_TESTS in Visual Studio) creates (and runs) pcre_test.bat (and depending -on your configuration options, possibly other test programs) in the build -directory. Pcre_test.bat runs RunTest.Bat with correct source and exe paths. - -For manual testing with RunTest.bat, provided the build dir is a subdirectory -of the source directory: Open command shell window. Chdir to the location -of your pcretest.exe and pcregrep.exe programs. Call RunTest.bat with -"..\RunTest.Bat" or "..\..\RunTest.bat" as appropriate. - -To run only a particular test with RunTest.Bat provide a test number argument. - -Otherwise: - -1. Copy RunTest.bat into the directory where pcretest.exe and pcregrep.exe - have been created. - -2. Edit RunTest.bat to indentify the full or relative location of - the pcre source (wherein which the testdata folder resides), e.g.: - - set srcdir=C:\pcre\pcre-8.20 - -3. In a Windows command environment, chdir to the location of your bat and - exe programs. - -4. Run RunTest.bat. Test outputs will automatically be compared to expected - results, and discrepancies will be identified in the console output. - -To independently test the just-in-time compiler, run pcre_jit_test.exe. -To test pcrecpp, run pcrecpp_unittest.exe, pcre_stringpiece_unittest.exe and -pcre_scanner_unittest.exe. - - -BUILDING UNDER WINDOWS CE WITH VISUAL STUDIO 200x - -Vincent Richomme sent a zip archive of files to help with this process. They -can be found in the file "pcre-vsbuild.zip" in the Contrib directory of the FTP -site. - - -BUILDING UNDER WINDOWS WITH BCC5.5 - -Michael Roy sent these comments about building PCRE under Windows with BCC5.5: - -Some of the core BCC libraries have a version of PCRE from 1998 built in, which -can lead to pcre_exec() giving an erroneous PCRE_ERROR_NULL from a version -mismatch. I'm including an easy workaround below, if you'd like to include it -in the non-unix instructions: - -When linking a project with BCC5.5, pcre.lib must be included before any of the -libraries cw32.lib, cw32i.lib, cw32mt.lib, and cw32mti.lib on the command line. - - -BUILDING USING BORLAND C++ BUILDER 2007 (CB2007) AND HIGHER - -A PCRE user sent these comments about this environment (see also the comment -from another user that follows them): - -The XE versions of C++ Builder come with a RegularExpressionsCore class which -contain a version of TPerlRegEx. However, direct use of the C PCRE library may -be desirable. - -The default makevp.bat, however, supplied with PCRE builds a version of PCRE -that is not usable with any version of C++ Builder because the compiler ships -with an embedded version of PCRE, version 2.01 from 1998! [See also the note -about BCC5.5 above.] If you want to use PCRE you'll need to rename the -functions (pcre_compile to pcre_compile_bcc, etc) or do as I have done and just -use the 16 bit versions. I'm using std::wstring everywhere anyway. Since the -embedded version of PCRE does not have the 16 bit function names, there is no -conflict. - -Building PCRE using a C++ Builder static library project file (recommended): - -1. Rename or remove pcre.h, pcreposi.h, and pcreposix.h from your C++ Builder -original include path. - -2. Download PCRE from pcre.org and extract to a directory. - -3. Rename pcre_chartables.c.dist to pcre_chartables.c, pcre.h.generic to -pcre.h, and config.h.generic to config.h. - -4. Edit pcre.h and pcre_config.c so that they include config.h. - -5. Edit config.h like so: - -Comment out the following lines: -#define PACKAGE "pcre" -#define PACKAGE_BUGREPORT "" -#define PACKAGE_NAME "PCRE" -#define PACKAGE_STRING "PCRE 8.32" -#define PACKAGE_TARNAME "pcre" -#define PACKAGE_URL "" -#define PACKAGE_VERSION "8.32" - -Add the following lines: -#ifndef SUPPORT_UTF -#define SUPPORT_UTF 100 // any value is fine -#endif - -#ifndef SUPPORT_UCP -#define SUPPORT_UCP 101 // any value is fine -#endif - -#ifndef SUPPORT_UCP -#define SUPPORT_PCRE16 102 // any value is fine -#endif - -#ifndef SUPPORT_UTF8 -#define SUPPORT_UTF8 103 // any value is fine -#endif - -6. Build a C++ Builder project using the IDE. Go to File / New / Other and -choose Static Library. You can name it pcre.cbproj or whatever. Now set your -paths by going to Project / Options. Set the Include path. Do this from the -"Base" option to apply to both Release and Debug builds. Now add the following -files to the project: - -pcre.h -pcre16_byte_order.c -pcre16_chartables.c -pcre16_compile.c -pcre16_config.c -pcre16_dfa_exec.c -pcre16_exec.c -pcre16_fullinfo.c -pcre16_get.c -pcre16_globals.c -pcre16_maketables.c -pcre16_newline.c -pcre16_ord2utf16.c -pcre16_printint.c -pcre16_refcount.c -pcre16_string_utils.c -pcre16_study.c -pcre16_tables.c -pcre16_ucd.c -pcre16_utf16_utils.c -pcre16_valid_utf16.c -pcre16_version.c -pcre16_xclass.c - -//Optional -pcre_version.c - -7. After compiling the .lib file, copy the .lib and header files to a project -you want to use PCRE with. Enjoy. - -Optional ... Building PCRE using the makevp.bat file: - -1. Edit makevp_c.txt and makevp_l.txt and change all the names to the 16 bit -versions. - -2. Edit makevp.bat and set the path to C++ Builder. Run makevp.bat. - -Another PCRE user added this comment: - -Another approach I successfully used for some years with BCB 5 and 6 was to -make sure that include and library paths of PCRE are configured before the -default paths of the IDE in the dialogs where one can manage those paths. -Afterwards one can open the project files using a text editor and manually add -the self created library for pcre itself, pcrecpp doesn't ship with the IDE, in -the library nodes where the IDE manages its own libraries to link against in -front of the IDE-own libraries. This way one can use the default PCRE function -names without getting access violations on runtime. - - <ALLLIB value="libpcre.lib $(LIBFILES) $(LIBRARIES) import32.lib cp32mt.lib"/> - - -BUILDING PCRE ON OPENVMS - -Stephen Hoffman sent the following, in December 2012: - -"Here <http://labs.hoffmanlabs.com/node/1847> is a very short write-up on the -OpenVMS port and here - -<http://labs.hoffmanlabs.com/labsnotes/pcre-vms-8_32.zip> - -is a zip with the OpenVMS files, and with one modified testing-related PCRE -file."

There are three sets of -functions, one for the 8-bit library, which processes strings of bytes, one for -the 16-bit library, which processes strings of 16-bit values, and one for the -32-bit library, which processes strings of 32-bit values. The distribution also -includes a set of C++ wrapper functions (see the pcrecpp man page for details), -courtesy of Google Inc., which can be used to call the 8-bit PCRE library from -C++. Other C++ wrappers have been created from time to time. See, for example: -https://github.com/YasserAsmi/regexp, which aims to be simple and similar in -style to the C API. - -The distribution also contains a set of C wrapper functions (again, just for -the 8-bit library) that are based on the POSIX regular expression API (see the -pcreposix man page). These end up in the library called libpcreposix. Note that -this just provides a POSIX calling interface to PCRE; the regular expressions -themselves still follow Perl syntax and semantics. The POSIX API is restricted, -and does not give full access to all of PCRE's facilities. - -The header file for the POSIX-style functions is called pcreposix.h. The -official POSIX name is regex.h, but I did not want to risk possible problems -with existing files of that name by distributing it that way. To use PCRE with -an existing program that uses the POSIX API, pcreposix.h will have to be -renamed or pointed at by a link. - -If you are using the POSIX interface to PCRE and there is already a POSIX regex -library installed on your system, as well as worrying about the regex.h header -file (as mentioned above), you must also take care when linking programs to -ensure that they link with PCRE's libpcreposix library. Otherwise they may pick -up the POSIX functions of the same name from the other library. - -One way of avoiding this confusion is to compile PCRE with the addition of --Dregcomp=PCREregcomp (and similarly for the other POSIX functions) to the -compiler flags (CFLAGS if you are using "configure" -- see below). This has the -effect of renaming the functions so that the names no longer clash. Of course, -you have to do the same thing for your applications, or write them using the -new names. - - -Documentation for PCRE ----------------------- - -If you install PCRE in the normal way on a Unix-like system, you will end up -with a set of man pages whose names all start with "pcre". The one that is just -called "pcre" lists all the others. In addition to these man pages, the PCRE -documentation is supplied in two other forms: - - 1. There are files called doc/pcre.txt, doc/pcregrep.txt, and - doc/pcretest.txt in the source distribution. The first of these is a - concatenation of the text forms of all the section 3 man pages except - the listing of pcredemo.c and those that summarize individual functions. - The other two are the text forms of the section 1 man pages for the - pcregrep and pcretest commands. These text forms are provided for ease of - scanning with text editors or similar tools. They are installed in - <prefix>/share/doc/pcre, where <prefix> is the installation prefix - (defaulting to /usr/local). - - 2. A set of files containing all the documentation in HTML form, hyperlinked - in various ways, and rooted in a file called index.html, is distributed in - doc/html and installed in <prefix>/share/doc/pcre/html. - -Users of PCRE have contributed files containing the documentation for various -releases in CHM format. These can be found in the Contrib directory of the FTP -site (see next section). - - -Contributions by users of PCRE ------------------------------- - -You can find contributions from PCRE users in the directory - - ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/Contrib - -There is a README file giving brief descriptions of what they are. Some are -complete in themselves; others are pointers to URLs containing relevant files. -Some of this material is likely to be well out-of-date. Several of the earlier -contributions provided support for compiling PCRE on various flavours of -Windows (I myself do not use Windows). Nowadays there is more Windows support -in the standard distribution, so these contibutions have been archived. - -A PCRE user maintains downloadable Windows binaries of the pcregrep and -pcretest programs here: - - http://www.rexegg.com/pcregrep-pcretest.html - - -Building PCRE on non-Unix-like systems --------------------------------------- - -For a non-Unix-like system, please read the comments in the file -NON-AUTOTOOLS-BUILD, though if your system supports the use of "configure" and -"make" you may be able to build PCRE using autotools in the same way as for -many Unix-like systems. - -PCRE can also be configured using the GUI facility provided by CMake's -cmake-gui command. This creates Makefiles, solution files, etc. The file -NON-AUTOTOOLS-BUILD has information about CMake. - -PCRE has been compiled on many different operating systems. It should be -straightforward to build PCRE on any system that has a Standard C compiler and -library, because it uses only Standard C functions. - - -Building PCRE without using autotools -------------------------------------- - -The use of autotools (in particular, libtool) is problematic in some -environments, even some that are Unix or Unix-like. See the NON-AUTOTOOLS-BUILD -file for ways of building PCRE without using autotools. - - -Building PCRE using autotools ------------------------------ - -If you are using HP's ANSI C++ compiler (aCC), please see the special note -in the section entitled "Using HP's ANSI C++ compiler (aCC)" below. - -The following instructions assume the use of the widely used "configure; make; -make install" (autotools) process. - -To build PCRE on system that supports autotools, first run the "configure" -command from the PCRE distribution directory, with your current directory set -to the directory where you want the files to be created. This command is a -standard GNU "autoconf" configuration script, for which generic instructions -are supplied in the file INSTALL. - -Most commonly, people build PCRE within its own distribution directory, and in -this case, on many systems, just running "./configure" is sufficient. However, -the usual methods of changing standard defaults are available. For example: - -CFLAGS='-O2 -Wall' ./configure --prefix=/opt/local - -This command specifies that the C compiler should be run with the flags '-O2 --Wall' instead of the default, and that "make install" should install PCRE -under /opt/local instead of the default /usr/local. - -If you want to build in a different directory, just run "configure" with that -directory as current. For example, suppose you have unpacked the PCRE source -into /source/pcre/pcre-xxx, but you want to build it in /build/pcre/pcre-xxx: - -cd /build/pcre/pcre-xxx -/source/pcre/pcre-xxx/configure - -PCRE is written in C and is normally compiled as a C library. However, it is -possible to build it as a C++ library, though the provided building apparatus -does not have any features to support this. - -There are some optional features that can be included or omitted from the PCRE -library. They are also documented in the pcrebuild man page. - -. By default, both shared and static libraries are built. You can change this - by adding one of these options to the "configure" command: - - --disable-shared - --disable-static - - (See also "Shared libraries on Unix-like systems" below.) - -. By default, only the 8-bit library is built. If you add --enable-pcre16 to - the "configure" command, the 16-bit library is also built. If you add - --enable-pcre32 to the "configure" command, the 32-bit library is also built. - If you want only the 16-bit or 32-bit library, use --disable-pcre8 to disable - building the 8-bit library. - -. If you are building the 8-bit library and want to suppress the building of - the C++ wrapper library, you can add --disable-cpp to the "configure" - command. Otherwise, when "configure" is run without --disable-pcre8, it will - try to find a C++ compiler and C++ header files, and if it succeeds, it will - try to build the C++ wrapper. - -. If you want to include support for just-in-time compiling, which can give - large performance improvements on certain platforms, add --enable-jit to the - "configure" command. This support is available only for certain hardware - architectures. If you try to enable it on an unsupported architecture, there - will be a compile time error. - -. When JIT support is enabled, pcregrep automatically makes use of it, unless - you add --disable-pcregrep-jit to the "configure" command. - -. If you want to make use of the support for UTF-8 Unicode character strings in - the 8-bit library, or UTF-16 Unicode character strings in the 16-bit library, - or UTF-32 Unicode character strings in the 32-bit library, you must add - --enable-utf to the "configure" command. Without it, the code for handling - UTF-8, UTF-16 and UTF-8 is not included in the relevant library. Even - when --enable-utf is included, the use of a UTF encoding still has to be - enabled by an option at run time. When PCRE is compiled with this option, its - input can only either be ASCII or UTF-8/16/32, even when running on EBCDIC - platforms. It is not possible to use both --enable-utf and --enable-ebcdic at - the same time. - -. There are no separate options for enabling UTF-8, UTF-16 and UTF-32 - independently because that would allow ridiculous settings such as requesting - UTF-16 support while building only the 8-bit library. However, the option - --enable-utf8 is retained for backwards compatibility with earlier releases - that did not support 16-bit or 32-bit character strings. It is synonymous with - --enable-utf. It is not possible to configure one library with UTF support - and the other without in the same configuration. - -. If, in addition to support for UTF-8/16/32 character strings, you want to - include support for the \P, \p, and \X sequences that recognize Unicode - character properties, you must add --enable-unicode-properties to the - "configure" command. This adds about 30K to the size of the library (in the - form of a property table); only the basic two-letter properties such as Lu - are supported. - -. You can build PCRE to recognize either CR or LF or the sequence CRLF or any - of the preceding, or any of the Unicode newline sequences as indicating the - end of a line. Whatever you specify at build time is the default; the caller - of PCRE can change the selection at run time. The default newline indicator - is a single LF character (the Unix standard). You can specify the default - newline indicator by adding --enable-newline-is-cr or --enable-newline-is-lf - or --enable-newline-is-crlf or --enable-newline-is-anycrlf or - --enable-newline-is-any to the "configure" command, respectively. - - If you specify --enable-newline-is-cr or --enable-newline-is-crlf, some of - the standard tests will fail, because the lines in the test files end with - LF. Even if the files are edited to change the line endings, there are likely - to be some failures. With --enable-newline-is-anycrlf or - --enable-newline-is-any, many tests should succeed, but there may be some - failures. - -. By default, the sequence \R in a pattern matches any Unicode line ending - sequence. This is independent of the option specifying what PCRE considers to - be the end of a line (see above). However, the caller of PCRE can restrict \R - to match only CR, LF, or CRLF. You can make this the default by adding - --enable-bsr-anycrlf to the "configure" command (bsr = "backslash R"). - -. When called via the POSIX interface, PCRE uses malloc() to get additional - storage for processing capturing parentheses if there are more than 10 of - them in a pattern. You can increase this threshold by setting, for example, - - --with-posix-malloc-threshold=20 - - on the "configure" command. - -. PCRE has a counter that limits the depth of nesting of parentheses in a - pattern. This limits the amount of system stack that a pattern uses when it - is compiled. The default is 250, but you can change it by setting, for - example, - - --with-parens-nest-limit=500 - -. PCRE has a counter that can be set to limit the amount of resources it uses - when matching a pattern. If the limit is exceeded during a match, the match - fails. The default is ten million. You can change the default by setting, for - example, - - --with-match-limit=500000 - - on the "configure" command. This is just the default; individual calls to - pcre_exec() can supply their own value. There is more discussion on the - pcreapi man page. - -. There is a separate counter that limits the depth of recursive function calls - during a matching process. This also has a default of ten million, which is - essentially "unlimited". You can change the default by setting, for example, - - --with-match-limit-recursion=500000 - - Recursive function calls use up the runtime stack; running out of stack can - cause programs to crash in strange ways. There is a discussion about stack - sizes in the pcrestack man page. - -. The default maximum compiled pattern size is around 64K. You can increase - this by adding --with-link-size=3 to the "configure" command. In the 8-bit - library, PCRE then uses three bytes instead of two for offsets to different - parts of the compiled pattern. In the 16-bit library, --with-link-size=3 is - the same as --with-link-size=4, which (in both libraries) uses four-byte - offsets. Increasing the internal link size reduces performance. In the 32-bit - library, the only supported link size is 4. - -. You can build PCRE so that its internal match() function that is called from - pcre_exec() does not call itself recursively. Instead, it uses memory blocks - obtained from the heap via the special functions pcre_stack_malloc() and - pcre_stack_free() to save data that would otherwise be saved on the stack. To - build PCRE like this, use - - --disable-stack-for-recursion - - on the "configure" command. PCRE runs more slowly in this mode, but it may be - necessary in environments with limited stack sizes. This applies only to the - normal execution of the pcre_exec() function; if JIT support is being - successfully used, it is not relevant. Equally, it does not apply to - pcre_dfa_exec(), which does not use deeply nested recursion. There is a - discussion about stack sizes in the pcrestack man page. - -. For speed, PCRE uses four tables for manipulating and identifying characters - whose code point values are less than 256. By default, it uses a set of - tables for ASCII encoding that is part of the distribution. If you specify - - --enable-rebuild-chartables - - a program called dftables is compiled and run in the default C locale when - you obey "make". It builds a source file called pcre_chartables.c. If you do - not specify this option, pcre_chartables.c is created as a copy of - pcre_chartables.c.dist. See "Character tables" below for further information. - -. It is possible to compile PCRE for use on systems that use EBCDIC as their - character code (as opposed to ASCII/Unicode) by specifying - - --enable-ebcdic - - This automatically implies --enable-rebuild-chartables (see above). However, - when PCRE is built this way, it always operates in EBCDIC. It cannot support - both EBCDIC and UTF-8/16/32. There is a second option, --enable-ebcdic-nl25, - which specifies that the code value for the EBCDIC NL character is 0x25 - instead of the default 0x15. - -. In environments where valgrind is installed, if you specify - - --enable-valgrind - - PCRE will use valgrind annotations to mark certain memory regions as - unaddressable. This allows it to detect invalid memory accesses, and is - mostly useful for debugging PCRE itself. - -. In environments where the gcc compiler is used and lcov version 1.6 or above - is installed, if you specify - - --enable-coverage - - the build process implements a code coverage report for the test suite. The - report is generated by running "make coverage". If ccache is installed on - your system, it must be disabled when building PCRE for coverage reporting. - You can do this by setting the environment variable CCACHE_DISABLE=1 before - running "make" to build PCRE. There is more information about coverage - reporting in the "pcrebuild" documentation. - -. The pcregrep program currently supports only 8-bit data files, and so - requires the 8-bit PCRE library. It is possible to compile pcregrep to use - libz and/or libbz2, in order to read .gz and .bz2 files (respectively), by - specifying one or both of - - --enable-pcregrep-libz - --enable-pcregrep-libbz2 - - Of course, the relevant libraries must be installed on your system. - -. The default size (in bytes) of the internal buffer used by pcregrep can be - set by, for example: - - --with-pcregrep-bufsize=51200 - - The value must be a plain integer. The default is 20480. - -. It is possible to compile pcretest so that it links with the libreadline - or libedit libraries, by specifying, respectively, - - --enable-pcretest-libreadline or --enable-pcretest-libedit - - If this is done, when pcretest's input is from a terminal, it reads it using - the readline() function. This provides line-editing and history facilities. - Note that libreadline is GPL-licenced, so if you distribute a binary of - pcretest linked in this way, there may be licensing issues. These can be - avoided by linking with libedit (which has a BSD licence) instead. - - Enabling libreadline causes the -lreadline option to be added to the pcretest - build. In many operating environments with a sytem-installed readline - library this is sufficient. However, in some environments (e.g. if an - unmodified distribution version of readline is in use), it may be necessary - to specify something like LIBS="-lncurses" as well. This is because, to quote - the readline INSTALL, "Readline uses the termcap functions, but does not link - with the termcap or curses library itself, allowing applications which link - with readline the to choose an appropriate library." If you get error - messages about missing functions tgetstr, tgetent, tputs, tgetflag, or tgoto, - this is the problem, and linking with the ncurses library should fix it. - -The "configure" script builds the following files for the basic C library: - -. Makefile the makefile that builds the library -. config.h build-time configuration options for the library -. pcre.h the public PCRE header file -. pcre-config script that shows the building settings such as CFLAGS - that were set for "configure" -. libpcre.pc ) data for the pkg-config command -. libpcre16.pc ) -. libpcre32.pc ) -. libpcreposix.pc ) -. libtool script that builds shared and/or static libraries - -Versions of config.h and pcre.h are distributed in the PCRE tarballs under the -names config.h.generic and pcre.h.generic. These are provided for those who -have to built PCRE without using "configure" or CMake. If you use "configure" -or CMake, the .generic versions are not used. - -When building the 8-bit library, if a C++ compiler is found, the following -files are also built: - -. libpcrecpp.pc data for the pkg-config command -. pcrecpparg.h header file for calling PCRE via the C++ wrapper -. pcre_stringpiece.h header for the C++ "stringpiece" functions - -The "configure" script also creates config.status, which is an executable -script that can be run to recreate the configuration, and config.log, which -contains compiler output from tests that "configure" runs. - -Once "configure" has run, you can run "make". This builds the the libraries -libpcre, libpcre16 and/or libpcre32, and a test program called pcretest. If you -enabled JIT support with --enable-jit, a test program called pcre_jit_test is -built as well. - -If the 8-bit library is built, libpcreposix and the pcregrep command are also -built, and if a C++ compiler was found on your system, and you did not disable -it with --disable-cpp, "make" builds the C++ wrapper library, which is called -libpcrecpp, as well as some test programs called pcrecpp_unittest, -pcre_scanner_unittest, and pcre_stringpiece_unittest. - -The command "make check" runs all the appropriate tests. Details of the PCRE -tests are given below in a separate section of this document. - -You can use "make install" to install PCRE into live directories on your -system. The following are installed (file names are all relative to the -<prefix> that is set when "configure" is run): - - Commands (bin): - pcretest - pcregrep (if 8-bit support is enabled) - pcre-config - - Libraries (lib): - libpcre16 (if 16-bit support is enabled) - libpcre32 (if 32-bit support is enabled) - libpcre (if 8-bit support is enabled) - libpcreposix (if 8-bit support is enabled) - libpcrecpp (if 8-bit and C++ support is enabled) - - Configuration information (lib/pkgconfig): - libpcre16.pc - libpcre32.pc - libpcre.pc - libpcreposix.pc - libpcrecpp.pc (if C++ support is enabled) - - Header files (include): - pcre.h - pcreposix.h - pcre_scanner.h ) - pcre_stringpiece.h ) if C++ support is enabled - pcrecpp.h ) - pcrecpparg.h ) - - Man pages (share/man/man{1,3}): - pcregrep.1 - pcretest.1 - pcre-config.1 - pcre.3 - pcre*.3 (lots more pages, all starting "pcre") - - HTML documentation (share/doc/pcre/html): - index.html - *.html (lots more pages, hyperlinked from index.html) - - Text file documentation (share/doc/pcre): - AUTHORS - COPYING - ChangeLog - LICENCE - NEWS - README - pcre.txt (a concatenation of the man(3) pages) - pcretest.txt the pcretest man page - pcregrep.txt the pcregrep man page - pcre-config.txt the pcre-config man page - -If you want to remove PCRE from your system, you can run "make uninstall". -This removes all the files that "make install" installed. However, it does not -remove any directories, because these are often shared with other programs. - - -Retrieving configuration information ------------------------------------- - -Running "make install" installs the command pcre-config, which can be used to -recall information about the PCRE configuration and installation. For example: - - pcre-config --version - -prints the version number, and - - pcre-config --libs - -outputs information about where the library is installed. This command can be -included in makefiles for programs that use PCRE, saving the programmer from -having to remember too many details. - -The pkg-config command is another system for saving and retrieving information -about installed libraries. Instead of separate commands for each library, a -single command is used. For example: - - pkg-config --cflags pcre - -The data is held in *.pc files that are installed in a directory called -<prefix>/lib/pkgconfig. - - -Shared libraries ----------------- - -The default distribution builds PCRE as shared libraries and static libraries, -as long as the operating system supports shared libraries. Shared library -support relies on the "libtool" script which is built as part of the -"configure" process. - -The libtool script is used to compile and link both shared and static -libraries. They are placed in a subdirectory called .libs when they are newly -built. The programs pcretest and pcregrep are built to use these uninstalled -libraries (by means of wrapper scripts in the case of shared libraries). When -you use "make install" to install shared libraries, pcregrep and pcretest are -automatically re-built to use the newly installed shared libraries before being -installed themselves. However, the versions left in the build directory still -use the uninstalled libraries. - -To build PCRE using static libraries only you must use --disable-shared when -configuring it. For example: - -./configure --prefix=/usr/gnu --disable-shared - -Then run "make" in the usual way. Similarly, you can use --disable-static to -build only shared libraries. - - -Cross-compiling using autotools -------------------------------- - -You can specify CC and CFLAGS in the normal way to the "configure" command, in -order to cross-compile PCRE for some other host. However, you should NOT -specify --enable-rebuild-chartables, because if you do, the dftables.c source -file is compiled and run on the local host, in order to generate the inbuilt -character tables (the pcre_chartables.c file). This will probably not work, -because dftables.c needs to be compiled with the local compiler, not the cross -compiler. - -When --enable-rebuild-chartables is not specified, pcre_chartables.c is created -by making a copy of pcre_chartables.c.dist, which is a default set of tables -that assumes ASCII code. Cross-compiling with the default tables should not be -a problem. - -If you need to modify the character tables when cross-compiling, you should -move pcre_chartables.c.dist out of the way, then compile dftables.c by hand and -run it on the local host to make a new version of pcre_chartables.c.dist. -Then when you cross-compile PCRE this new version of the tables will be used. - - -Using HP's ANSI C++ compiler (aCC) ----------------------------------- - -Unless C++ support is disabled by specifying the "--disable-cpp" option of the -"configure" script, you must include the "-AA" option in the CXXFLAGS -environment variable in order for the C++ components to compile correctly. - -Also, note that the aCC compiler on PA-RISC platforms may have a defect whereby -needed libraries fail to get included when specifying the "-AA" compiler -option. If you experience unresolved symbols when linking the C++ programs, -use the workaround of specifying the following environment variable prior to -running the "configure" script: - - CXXLDFLAGS="-lstd_v2 -lCsup_v2" - - -Compiling in Tru64 using native compilers ------------------------------------------ - -The following error may occur when compiling with native compilers in the Tru64 -operating system: - - CXX libpcrecpp_la-pcrecpp.lo -cxx: Error: /usr/lib/cmplrs/cxx/V7.1-006/include/cxx/iosfwd, line 58: #error - directive: "cannot include iosfwd -- define __USE_STD_IOSTREAM to - override default - see section 7.1.2 of the C++ Using Guide" -#error "cannot include iosfwd -- define __USE_STD_IOSTREAM to override default -- see section 7.1.2 of the C++ Using Guide" - -This may be followed by other errors, complaining that 'namespace "std" has no -member'. The solution to this is to add the line - -#define __USE_STD_IOSTREAM 1 - -to the config.h file. - - -Using Sun's compilers for Solaris ---------------------------------- - -A user reports that the following configurations work on Solaris 9 sparcv9 and -Solaris 9 x86 (32-bit): - - Solaris 9 sparcv9: ./configure --disable-cpp CC=/bin/cc CFLAGS="-m64 -g" - Solaris 9 x86: ./configure --disable-cpp CC=/bin/cc CFLAGS="-g" - - -Using PCRE from MySQL ---------------------- - -On systems where both PCRE and MySQL are installed, it is possible to make use -of PCRE from within MySQL, as an alternative to the built-in pattern matching. -There is a web page that tells you how to do this: - - http://www.mysqludf.org/lib_mysqludf_preg/index.php - - -Making new tarballs -------------------- - -The command "make dist" creates three PCRE tarballs, in tar.gz, tar.bz2, and -zip formats. The command "make distcheck" does the same, but then does a trial -build of the new distribution to ensure that it works. - -If you have modified any of the man page sources in the doc directory, you -should first run the PrepareRelease script before making a distribution. This -script creates the .txt and HTML forms of the documentation from the man pages. - - -Testing PCRE ------------- - -To test the basic PCRE library on a Unix-like system, run the RunTest script. -There is another script called RunGrepTest that tests the options of the -pcregrep command. If the C++ wrapper library is built, three test programs -called pcrecpp_unittest, pcre_scanner_unittest, and pcre_stringpiece_unittest -are also built. When JIT support is enabled, another test program called -pcre_jit_test is built. - -Both the scripts and all the program tests are run if you obey "make check" or -"make test". For other environments, see the instructions in -NON-AUTOTOOLS-BUILD. - -The RunTest script runs the pcretest test program (which is documented in its -own man page) on each of the relevant testinput files in the testdata -directory, and compares the output with the contents of the corresponding -testoutput files. RunTest uses a file called testtry to hold the main output -from pcretest. Other files whose names begin with "test" are used as working -files in some tests. - -Some tests are relevant only when certain build-time options were selected. For -example, the tests for UTF-8/16/32 support are run only if --enable-utf was -used. RunTest outputs a comment when it skips a test. - -Many of the tests that are not skipped are run up to three times. The second -run forces pcre_study() to be called for all patterns except for a few in some -tests that are marked "never study" (see the pcretest program for how this is -done). If JIT support is available, the non-DFA tests are run a third time, -this time with a forced pcre_study() with the PCRE_STUDY_JIT_COMPILE option. -This testing can be suppressed by putting "nojit" on the RunTest command line. - -The entire set of tests is run once for each of the 8-bit, 16-bit and 32-bit -libraries that are enabled. If you want to run just one set of tests, call -RunTest with either the -8, -16 or -32 option. - -If valgrind is installed, you can run the tests under it by putting "valgrind" -on the RunTest command line. To run pcretest on just one or more specific test -files, give their numbers as arguments to RunTest, for example: - - RunTest 2 7 11 - -You can also specify ranges of tests such as 3-6 or 3- (meaning 3 to the -end), or a number preceded by ~ to exclude a test. For example: - - Runtest 3-15 ~10 - -This runs tests 3 to 15, excluding test 10, and just ~13 runs all the tests -except test 13. Whatever order the arguments are in, the tests are always run -in numerical order. - -You can also call RunTest with the single argument "list" to cause it to output -a list of tests. - -The first test file can be fed directly into the perltest.pl script to check -that Perl gives the same results. The only difference you should see is in the -first few lines, where the Perl version is given instead of the PCRE version. - -The second set of tests check pcre_fullinfo(), pcre_study(), -pcre_copy_substring(), pcre_get_substring(), pcre_get_substring_list(), error -detection, and run-time flags that are specific to PCRE, as well as the POSIX -wrapper API. It also uses the debugging flags to check some of the internals of -pcre_compile(). - -If you build PCRE with a locale setting that is not the standard C locale, the -character tables may be different (see next paragraph). In some cases, this may -cause failures in the second set of tests. For example, in a locale where the -isprint() function yields TRUE for characters in the range 128-255, the use of -[:isascii:] inside a character class defines a different set of characters, and -this shows up in this test as a difference in the compiled code, which is being -listed for checking. Where the comparison test output contains [\x00-\x7f] the -test will contain [\x00-\xff], and similarly in some other cases. This is not a -bug in PCRE. - -The third set of tests checks pcre_maketables(), the facility for building a -set of character tables for a specific locale and using them instead of the -default tables. The tests make use of the "fr_FR" (French) locale. Before -running the test, the script checks for the presence of this locale by running -the "locale" command. If that command fails, or if it doesn't include "fr_FR" -in the list of available locales, the third test cannot be run, and a comment -is output to say why. If running this test produces instances of the error - - ** Failed to set locale "fr_FR" - -in the comparison output, it means that locale is not available on your system, -despite being listed by "locale". This does not mean that PCRE is broken. - -[If you are trying to run this test on Windows, you may be able to get it to -work by changing "fr_FR" to "french" everywhere it occurs. Alternatively, use -RunTest.bat. The version of RunTest.bat included with PCRE 7.4 and above uses -Windows versions of test 2. More info on using RunTest.bat is included in the -document entitled NON-UNIX-USE.] - -The fourth and fifth tests check the UTF-8/16/32 support and error handling and -internal UTF features of PCRE that are not relevant to Perl, respectively. The -sixth and seventh tests do the same for Unicode character properties support. - -The eighth, ninth, and tenth tests check the pcre_dfa_exec() alternative -matching function, in non-UTF-8/16/32 mode, UTF-8/16/32 mode, and UTF-8/16/32 -mode with Unicode property support, respectively. - -The eleventh test checks some internal offsets and code size features; it is -run only when the default "link size" of 2 is set (in other cases the sizes -change) and when Unicode property support is enabled. - -The twelfth test is run only when JIT support is available, and the thirteenth -test is run only when JIT support is not available. They test some JIT-specific -features such as information output from pcretest about JIT compilation. - -The fourteenth, fifteenth, and sixteenth tests are run only in 8-bit mode, and -the seventeenth, eighteenth, and nineteenth tests are run only in 16/32-bit -mode. These are tests that generate different output in the two modes. They are -for general cases, UTF-8/16/32 support, and Unicode property support, -respectively. - -The twentieth test is run only in 16/32-bit mode. It tests some specific -16/32-bit features of the DFA matching engine. - -The twenty-first and twenty-second tests are run only in 16/32-bit mode, when -the link size is set to 2 for the 16-bit library. They test reloading -pre-compiled patterns. - -The twenty-third and twenty-fourth tests are run only in 16-bit mode. They are -for general cases, and UTF-16 support, respectively. - -The twenty-fifth and twenty-sixth tests are run only in 32-bit mode. They are -for general cases, and UTF-32 support, respectively. - - -Character tables ----------------- - -For speed, PCRE uses four tables for manipulating and identifying characters -whose code point values are less than 256. The final argument of the -pcre_compile() function is a pointer to a block of memory containing the -concatenated tables. A call to pcre_maketables() can be used to generate a set -of tables in the current locale. If the final argument for pcre_compile() is -passed as NULL, a set of default tables that is built into the binary is used. - -The source file called pcre_chartables.c contains the default set of tables. By -default, this is created as a copy of pcre_chartables.c.dist, which contains -tables for ASCII coding. However, if --enable-rebuild-chartables is specified -for ./configure, a different version of pcre_chartables.c is built by the -program dftables (compiled from dftables.c), which uses the ANSI C character -handling functions such as isalnum(), isalpha(), isupper(), islower(), etc. to -build the table sources. This means that the default C locale which is set for -your system will control the contents of these default tables. You can change -the default tables by editing pcre_chartables.c and then re-building PCRE. If -you do this, you should take care to ensure that the file does not get -automatically re-generated. The best way to do this is to move -pcre_chartables.c.dist out of the way and replace it with your customized -tables. - -When the dftables program is run as a result of --enable-rebuild-chartables, -it uses the default C locale that is set on your system. It does not pay -attention to the LC_xxx environment variables. In other words, it uses the -system's default locale rather than whatever the compiling user happens to have -set. If you really do want to build a source set of character tables in a -locale that is specified by the LC_xxx variables, you can run the dftables -program by hand with the -L option. For example: - - ./dftables -L pcre_chartables.c.special - -The first two 256-byte tables provide lower casing and case flipping functions, -respectively. The next table consists of three 32-byte bit maps which identify -digits, "word" characters, and white space, respectively. These are used when -building 32-byte bit maps that represent character classes for code points less -than 256. - -The final 256-byte table has bits indicating various character types, as -follows: - - 1 white space character - 2 letter - 4 decimal digit - 8 hexadecimal digit - 16 alphanumeric or '_' - 128 regular expression metacharacter or binary zero - -You should not alter the set of characters that contain the 128 bit, as that -will cause PCRE to malfunction. - - -File manifest -------------- - -The distribution should contain the files listed below. Where a file name is -given as pcre[16|32]_xxx it means that there are three files, one with the name -pcre_xxx, one with the name pcre16_xx, and a third with the name pcre32_xxx. - -(A) Source files of the PCRE library functions and their headers: -

-@rem This file must use CRLF linebreaks to function properly
-@rem and requires both pcretest and pcregrep
-@rem This file was originally contributed by Ralf Junker, and touched up by
-@rem Daniel Richard G. Tests 10-12 added by Philip H.
-@rem Philip H also changed test 3 to use "wintest" files.
-@rem
-@rem Updated by Tom Fortmann to support explicit test numbers on the command line.
-@rem Added argument validation and added error reporting.
-@rem
-@rem MS Windows batch file to run pcretest on testfiles with the correct
-@rem options.
-@rem
-@rem Sheri Pierce added logic to skip feature dependent tests
-@rem tests 4 5 9 15 and 18 require utf support
-@rem tests 6 7 10 16 and 19 require ucp support
-@rem 11 requires ucp and link size 2
-@rem 12 requires presence of jit support
-@rem 13 requires absence of jit support
-@rem Sheri P also added override tests for study and jit testing
-@rem Zoltan Herczeg added libpcre16 support
-@rem Zoltan Herczeg added libpcre32 support

This is necessary if you are running in an -EBCDIC environment, or if you want to default to a different encoding, for -example ISO-8859-1. When dftables is run, it creates these tables in the -current locale. If PCRE is configured with --enable-rebuild-chartables, this -happens automatically. - -The following #includes are present because without them gcc 4.x may remove the -array definition from the final binary if PCRE is built into a static library -and dead code stripping is activated. This leads to link errors. Pulling in the -header ensures that the array gets flagged as "someone outside this compilation -unit might reference this" and so it will always be supplied to the linker. */ - -#ifdef HAVE_CONFIG_H -#include "config.h" -#endif - -#include "pcre_internal.h" - -const pcre_uint8 PRIV(default_tables)[] = { - -/* This table is a lower casing table. */ - - 0, 1, 2, 3, 4, 5, 6, 7, - 8, 9, 10, 11, 12, 13, 14, 15, - 16, 17, 18, 19, 20, 21, 22, 23, - 24, 25, 26, 27, 28, 29, 30, 31, - 32, 33, 34, 35, 36, 37, 38, 39, - 40, 41, 42, 43, 44, 45, 46, 47, - 48, 49, 50, 51, 52, 53, 54, 55, - 56, 57, 58, 59, 60, 61, 62, 63, - 64, 97, 98, 99,100,101,102,103, - 104,105,106,107,108,109,110,111, - 112,113,114,115,116,117,118,119, - 120,121,122, 91, 92, 93, 94, 95, - 96, 97, 98, 99,100,101,102,103, - 104,105,106,107,108,109,110,111, - 112,113,114,115,116,117,118,119, - 120,121,122,123,124,125,126,127, - 128,129,130,131,132,133,134,135, - 136,137,138,139,140,141,142,143, - 144,145,146,147,148,149,150,151, - 152,153,154,155,156,157,158,159, - 160,161,162,163,164,165,166,167, - 168,169,170,171,172,173,174,175, - 176,177,178,179,180,181,182,183, - 184,185,186,187,188,189,190,191, - 192,193,194,195,196,197,198,199, - 200,201,202,203,204,205,206,207, - 208,209,210,211,212,213,214,215, - 216,217,218,219,220,221,222,223, - 224,225,226,227,228,229,230,231, - 232,233,234,235,236,237,238,239, - 240,241,242,243,244,245,246,247, - 248,249,250,251,252,253,254,255, - -/* This table is a case flipping table. */ - - 0, 1, 2, 3, 4, 5, 6, 7, - 8, 9, 10, 11, 12, 13, 14, 15, - 16, 17, 18, 19, 20, 21, 22, 23, - 24, 25, 26, 27, 28, 29, 30, 31, - 32, 33, 34, 35, 36, 37, 38, 39, - 40, 41, 42, 43, 44, 45, 46, 47, - 48, 49, 50, 51, 52, 53, 54, 55, - 56, 57, 58, 59, 60, 61, 62, 63, - 64, 97, 98, 99,100,101,102,103, - 104,105,106,107,108,109,110,111, - 112,113,114,115,116,117,118,119, - 120,121,122, 91, 92, 93, 94, 95, - 96, 65, 66, 67, 68, 69, 70, 71, - 72, 73, 74, 75, 76, 77, 78, 79, - 80, 81, 82, 83, 84, 85, 86, 87, - 88, 89, 90,123,124,125,126,127, - 128,129,130,131,132,133,134,135, - 136,137,138,139,140,141,142,143, - 144,145,146,147,148,149,150,151, - 152,153,154,155,156,157,158,159, - 160,161,162,163,164,165,166,167, - 168,169,170,171,172,173,174,175, - 176,177,178,179,180,181,182,183, - 184,185,186,187,188,189,190,191, - 192,193,194,195,196,197,198,199, - 200,201,202,203,204,205,206,207, - 208,209,210,211,212,213,214,215, - 216,217,218,219,220,221,222,223, - 224,225,226,227,228,229,230,231, - 232,233,234,235,236,237,238,239, - 240,241,242,243,244,245,246,247, - 248,249,250,251,252,253,254,255, - -/* This table contains bit maps for various character classes.

Nevertheless, some regular expressions can cause -it to recurse to a great depth. I was writing for Unix, so I just let it call -itself recursively. This uses the stack for saving everything that has to be -saved for a recursive call. On Unix, the stack can be large, and this works -fine. - -It turns out that on some non-Unix-like systems there are problems with -programs that use a lot of stack. (This despite the fact that every last chip -has oodles of memory these days, and techniques for extending the stack have -been known for decades.) So.... - -There is a fudge, triggered by defining NO_RECURSE, which avoids recursive -calls by keeping local variables that need to be preserved in blocks of memory -obtained from malloc() instead instead of on the stack. Macros are used to -achieve this so that the actual code doesn't look very different to what it -always used to. - -The original heap-recursive code used longjmp(). However, it seems that this -can be very slow on some operating systems. Following a suggestion from Stan -Switzer, the use of longjmp() has been abolished, at the cost of having to -provide a unique number for each call to RMATCH. There is no way of generating -a sequence of numbers at compile time in C. I have given them names, to make -them stand out more clearly. - -Crude tests on x86 Linux show a small speedup of around 5-8%. However, on -FreeBSD, avoiding longjmp() more than halves the time taken to run the standard -tests. Furthermore, not using longjmp() means that local dynamic variables -don't have indeterminate values; this has meant that the frame size can be -reduced because the result can be "passed back" by straight setting of the -variable instead of being passed in the frame. -**************************************************************************** -***************************************************************************/ - -/* Numbers for RMATCH calls.

The basic blocks of regular expressions are condition checkers -whose execute different commands depending on the result of the condition check. -The relationship between the operators can be horizontal (concatenation) and -vertical (sub-expression) (See struct backtrack_common for more details). - - 'ab' - 'a' and 'b' regexps are concatenated - 'a+' - 'a' is the sub-expression of the '+' operator - -The condition checkers are boolean (true/false) checkers. Machine code is generated -for the checker itself and for the actions depending on the result of the checker. -The 'true' case is called as the matching path (expected path), and the other is called as -the 'backtrack' path. Branch instructions are expesive for all CPUs, so we avoid taken -branches on the matching path. - - Greedy star operator (*) : - Matching path: match happens. - Backtrack path: match failed. - Non-greedy star operator (*?) : - Matching path: no need to perform a match. - Backtrack path: match is required. - -The following example shows how the code generated for a capturing bracket -with two alternatives. Let A, B, C, D are arbirary regular expressions, and -we have the following regular expression: - - A(B|C)D - -The generated code will be the following: - - A matching path - '(' matching path (pushing arguments to the stack) - B matching path - ')' matching path (pushing arguments to the stack) - D matching path - return with successful match - - D backtrack path - ')' backtrack path (If we arrived from "C" jump to the backtrack of "C") - B backtrack path - C expected path - jump to D matching path - C backtrack path - A backtrack path - - Notice, that the order of backtrack code paths are the opposite of the fast - code paths. In this way the topmost value on the stack is always belong - to the current backtrack code path. The backtrack path must check - whether there is a next alternative. If so, it needs to jump back to - the matching path eventually.

RE supports -// Perl-style regular expressions (with extensions like \d, \w, \s, -// ...). -// -// ----------------------------------------------------------------------- -// REGEXP SYNTAX: -// -// This module is part of the pcre library and hence supports its syntax -// for regular expressions. -// -// The syntax is pretty similar to Perl's. For those not familiar -// with Perl's regular expressions, here are some examples of the most -// commonly used extensions: -// -// "hello (\\w+) world" -- \w matches a "word" character -// "version (\\d+)" -- \d matches a digit -// "hello\\s+world" -- \s matches any whitespace character -// "\\b(\\w+)\\b" -- \b matches empty string at a word boundary -// "(?i)hello" -- (?i) turns on case-insensitive matching -// "/\\*(.*?)\\*/" -- .*? matches . minimum no. of times possible -// -// ----------------------------------------------------------------------- -// MATCHING INTERFACE: -// -// The "FullMatch" operation checks that supplied text matches a -// supplied pattern exactly. -// -// Example: successful match -// pcrecpp::RE re("h.*o"); -// re.FullMatch("hello"); -// -// Example: unsuccessful match (requires full match): -// pcrecpp::RE re("e"); -// !re.FullMatch("hello"); -// -// Example: creating a temporary RE object: -// pcrecpp::RE("h.*o").FullMatch("hello"); -// -// You can pass in a "const char*" or a "string" for "text". The -// examples below tend to use a const char*. -// -// You can, as in the different examples above, store the RE object -// explicitly in a variable or use a temporary RE object. The -// examples below use one mode or the other arbitrarily. Either -// could correctly be used for any of these examples. -// -// ----------------------------------------------------------------------- -// MATCHING WITH SUB-STRING EXTRACTION: -// -// You can supply extra pointer arguments to extract matched subpieces. -// -// Example: extracts "ruby" into "s" and 1234 into "i" -// int i; -// string s; -// pcrecpp::RE re("(\\w+):(\\d+)"); -// re.FullMatch("ruby:1234", &s, &i); -// -// Example: does not try to extract any extra sub-patterns -// re.FullMatch("ruby:1234", &s); -// -// Example: does not try to extract into NULL -// re.FullMatch("ruby:1234", NULL, &i); -// -// Example: integer overflow causes failure -// !re.FullMatch("ruby:1234567891234", NULL, &i); -// -// Example: fails because there aren't enough sub-patterns: -// !pcrecpp::RE("\\w+:\\d+").FullMatch("ruby:1234", &s); -// -// Example: fails because string cannot be stored in integer -// !pcrecpp::RE("(.*)").FullMatch("ruby", &i); -// -// The provided pointer arguments can be pointers to any scalar numeric -// type, or one of -// string (matched piece is copied to string) -// StringPiece (StringPiece is mutated to point to matched piece) -// T (where "bool T::ParseFrom(const char*, int)" exists) -// NULL (the corresponding matched sub-pattern is not copied) -// -// CAVEAT: An optional sub-pattern that does not exist in the matched -// string is assigned the empty string. Therefore, the following will -// return false (because the empty string is not a valid number): -// int number; -// pcrecpp::RE::FullMatch("abc", "[a-z]+(\\d+)?", &number); -// -// ----------------------------------------------------------------------- -// DO_MATCH -// -// The matching interface supports at most 16 arguments per call. -// If you need more, consider using the more general interface -// pcrecpp::RE::DoMatch(). See pcrecpp.h for the signature for DoMatch. -// -// ----------------------------------------------------------------------- -// PARTIAL MATCHES -// -// You can use the "PartialMatch" operation when you want the pattern -// to match any substring of the text. -// -// Example: simple search for a string: -// pcrecpp::RE("ell").PartialMatch("hello"); -// -// Example: find first number in a string: -// int number; -// pcrecpp::RE re("(\\d+)"); -// re.PartialMatch("x*100 + 20", &number); -// assert(number == 100); -// -// ----------------------------------------------------------------------- -// UTF-8 AND THE MATCHING INTERFACE: -// -// By default, pattern and text are plain text, one byte per character. -// The UTF8 flag, passed to the constructor, causes both pattern -// and string to be treated as UTF-8 text, still a byte stream but -// potentially multiple bytes per character. In practice, the text -// is likelier to be UTF-8 than the pattern, but the match returned -// may depend on the UTF8 flag, so always use it when matching -// UTF8 text. E.g., "." will match one byte normally but with UTF8 -// set may match up to three bytes of a multi-byte character. -// -// Example: -// pcrecpp::RE_Options options; -// options.set_utf8(); -// pcrecpp::RE re(utf8_pattern, options); -// re.FullMatch(utf8_string); -// -// Example: using the convenience function UTF8(): -// pcrecpp::RE re(utf8_pattern, pcrecpp::UTF8()); -// re.FullMatch(utf8_string); -// -// NOTE: The UTF8 option is ignored if pcre was not configured with the -// --enable-utf8 flag. -// -// ----------------------------------------------------------------------- -// PASSING MODIFIERS TO THE REGULAR EXPRESSION ENGINE -// -// PCRE defines some modifiers to change the behavior of the regular -// expression engine. -// The C++ wrapper defines an auxiliary class, RE_Options, as a vehicle -// to pass such modifiers to a RE class. -// -// Currently, the following modifiers are supported -// -// modifier description Perl corresponding -// -// PCRE_CASELESS case insensitive match /i -// PCRE_MULTILINE multiple lines match /m -// PCRE_DOTALL dot matches newlines /s -// PCRE_DOLLAR_ENDONLY $ matches only at end N/A -// PCRE_EXTRA strict escape parsing N/A -// PCRE_EXTENDED ignore whitespaces /x -// PCRE_UTF8 handles UTF8 chars built-in -// PCRE_UNGREEDY reverses * and *? N/A -// PCRE_NO_AUTO_CAPTURE disables matching parens N/A (*) -// -// (For a full account on how each modifier works, please check the -// PCRE API reference manual). -// -// (*) Both Perl and PCRE allow non matching parentheses by means of the -// "?:" modifier within the pattern itself. e.g. (?:ab|cd) does not -// capture, while (ab|cd) does. -// -// For each modifier, there are two member functions whose name is made -// out of the modifier in lowercase, without the "PCRE_" prefix. For -// instance, PCRE_CASELESS is handled by -// bool caseless(), -// which returns true if the modifier is set, and -// RE_Options & set_caseless(bool), -// which sets or unsets the modifier. -// -// Moreover, PCRE_EXTRA_MATCH_LIMIT can be accessed through the -// set_match_limit() and match_limit() member functions. -// Setting match_limit to a non-zero value will limit the executation of -// pcre to keep it from doing bad things like blowing the stack or taking -// an eternity to return a result. A value of 5000 is good enough to stop -// stack blowup in a 2MB thread stack. Setting match_limit to zero will -// disable match limiting. Alternately, you can set match_limit_recursion() -// which uses PCRE_EXTRA_MATCH_LIMIT_RECURSION to limit how much pcre -// recurses. match_limit() caps the number of matches pcre does; -// match_limit_recrusion() caps the depth of recursion. -// -// Normally, to pass one or more modifiers to a RE class, you declare -// a RE_Options object, set the appropriate options, and pass this -// object to a RE constructor. Example: -// -// RE_options opt; -// opt.set_caseless(true); -// -// if (RE("HELLO", opt).PartialMatch("hello world")) ... -// -// RE_options has two constructors. The default constructor takes no -// arguments and creates a set of flags that are off by default. -// -// The optional parameter 'option_flags' is to facilitate transfer -// of legacy code from C programs. This lets you do -// RE(pattern, RE_Options(PCRE_CASELESS|PCRE_MULTILINE)).PartialMatch(str); -// -// But new code is better off doing -// RE(pattern, -// RE_Options().set_caseless(true).set_multiline(true)).PartialMatch(str); -// (See below) -// -// If you are going to pass one of the most used modifiers, there are some -// convenience functions that return a RE_Options class with the -// appropriate modifier already set: -// CASELESS(), UTF8(), MULTILINE(), DOTALL(), EXTENDED() -// -// If you need to set several options at once, and you don't want to go -// through the pains of declaring a RE_Options object and setting several -// options, there is a parallel method that give you such ability on the -// fly. You can concatenate several set_xxxxx member functions, since each -// of them returns a reference to its class object. e.g.: to pass -// PCRE_CASELESS, PCRE_EXTENDED, and PCRE_MULTILINE to a RE with one -// statement, you may write -// -// RE(" ^ xyz \\s+ .* blah$", RE_Options() -// .set_caseless(true) -// .set_extended(true) -// .set_multiline(true)).PartialMatch(sometext); -// -// ----------------------------------------------------------------------- -// SCANNING TEXT INCREMENTALLY -// -// The "Consume" operation may be useful if you want to repeatedly -// match regular expressions at the front of a string and skip over -// them as they match. This requires use of the "StringPiece" type, -// which represents a sub-range of a real string. Like RE, StringPiece -// is defined in the pcrecpp namespace. -// -// Example: read lines of the form "var = value" from a string. -// string contents = ...; // Fill string somehow -// pcrecpp::StringPiece input(contents); // Wrap in a StringPiece -// -// string var; -// int value; -// pcrecpp::RE re("(\\w+) = (\\d+)\n"); -// while (re.Consume(&input, &var, &value)) { -// ...; -// } -// -// Each successful call to "Consume" will set "var/value", and also -// advance "input" so it points past the matched text. -// -// The "FindAndConsume" operation is similar to "Consume" but does not -// anchor your match at the beginning of the string. For example, you -// could extract all words from a string by repeatedly calling -// pcrecpp::RE("(\\w+)").FindAndConsume(&input, &word) -// -// ----------------------------------------------------------------------- -// PARSING HEX/OCTAL/C-RADIX NUMBERS -// -// By default, if you pass a pointer to a numeric value, the -// corresponding text is interpreted as a base-10 number. You can -// instead wrap the pointer with a call to one of the operators Hex(), -// Octal(), or CRadix() to interpret the text in another base. The -// CRadix operator interprets C-style "0" (base-8) and "0x" (base-16) -// prefixes, but defaults to base-10. -// -// Example: -// int a, b, c, d; -// pcrecpp::RE re("(.*) (.*) (.*) (.*)"); -// re.FullMatch("100 40 0100 0x40", -// pcrecpp::Octal(&a), pcrecpp::Hex(&b), -// pcrecpp::CRadix(&c), pcrecpp::CRadix(&d)); -// will leave 64 in a, b, c, and d. -// -// ----------------------------------------------------------------------- -// REPLACING PARTS OF STRINGS -// -// You can replace the first match of "pattern" in "str" with -// "rewrite". Within "rewrite", backslash-escaped digits (\1 to \9) -// can be used to insert text matching corresponding parenthesized -// group from the pattern. \0 in "rewrite" refers to the entire -// matching text. E.g., -// -// string s = "yabba dabba doo"; -// pcrecpp::RE("b+").Replace("d", &s); -// -// will leave "s" containing "yada dabba doo". The result is true if -// the pattern matches and a replacement occurs, or false otherwise. -// -// GlobalReplace() is like Replace(), except that it replaces all -// occurrences of the pattern in the string with the rewrite. -// Replacements are not subject to re-matching. E.g., -// -// string s = "yabba dabba doo"; -// pcrecpp::RE("b+").GlobalReplace("d", &s); -// -// will leave "s" containing "yada dada doo". It returns the number -// of replacements made. -// -// Extract() is like Replace(), except that if the pattern matches, -// "rewrite" is copied into "out" (an additional argument) with -// substitutions. The non-matching portions of "text" are ignored. -// Returns true iff a match occurred and the extraction happened -// successfully. If no match occurs, the string is left unaffected. - - -#include <string> -#include <pcre.h> -#include <pcrecpparg.h> // defines the Arg class -// This isn't technically needed here, but we include it -// anyway so folks who include pcrecpp.h don't have to. -#include <pcre_stringpiece.h> - -namespace pcrecpp { - -#define PCRE_SET_OR_CLEAR(b, o) \ - if (b) all_options_ |= (o); else all_options_ &= ~(o); \ - return *this - -#define PCRE_IS_SET(o) \ - (all_options_ & o) == o - -/***** Compiling regular expressions: the RE class *****/ - -// RE_Options allow you to set options to be passed along to pcre, -// along with other options we put on top of pcre. -// Only 9 modifiers, plus match_limit and match_limit_recursion, -// are supported now. -class PCRECPP_EXP_DEFN RE_Options { - public: - // constructor - RE_Options() : match_limit_(0), match_limit_recursion_(0), all_options_(0) {} - - // alternative constructor. - // To facilitate transfer of legacy code from C programs - // - // This lets you do - // RE(pattern, RE_Options(PCRE_CASELESS|PCRE_MULTILINE)).PartialMatch(str); - // But new code is better off doing - // RE(pattern, - // RE_Options().set_caseless(true).set_multiline(true)).PartialMatch(str); - RE_Options(int option_flags) : match_limit_(0), match_limit_recursion_(0), - all_options_(option_flags) {} - // we're fine with the default destructor, copy constructor, etc. - - // accessors and mutators - int match_limit() const { return match_limit_; }; - RE_Options &set_match_limit(int limit) { - match_limit_ = limit; - return *this; - } - - int match_limit_recursion() const { return match_limit_recursion_; }; - RE_Options &set_match_limit_recursion(int limit) { - match_limit_recursion_ = limit; - return *this; - } - - bool caseless() const { - return PCRE_IS_SET(PCRE_CASELESS); - } - RE_Options &set_caseless(bool x) { - PCRE_SET_OR_CLEAR(x, PCRE_CASELESS); - } - - bool multiline() const { - return PCRE_IS_SET(PCRE_MULTILINE); - } - RE_Options &set_multiline(bool x) { - PCRE_SET_OR_CLEAR(x, PCRE_MULTILINE); - } - - bool dotall() const { - return PCRE_IS_SET(PCRE_DOTALL); - } - RE_Options &set_dotall(bool x) { - PCRE_SET_OR_CLEAR(x, PCRE_DOTALL); - } - - bool extended() const { - return PCRE_IS_SET(PCRE_EXTENDED); - } - RE_Options &set_extended(bool x) { - PCRE_SET_OR_CLEAR(x, PCRE_EXTENDED); - } - - bool dollar_endonly() const { - return PCRE_IS_SET(PCRE_DOLLAR_ENDONLY); - } - RE_Options &set_dollar_endonly(bool x) { - PCRE_SET_OR_CLEAR(x, PCRE_DOLLAR_ENDONLY); - } - - bool extra() const { - return PCRE_IS_SET(PCRE_EXTRA); - } - RE_Options &set_extra(bool x) { - PCRE_SET_OR_CLEAR(x, PCRE_EXTRA); - } - - bool ungreedy() const { - return PCRE_IS_SET(PCRE_UNGREEDY); - } - RE_Options &set_ungreedy(bool x) { - PCRE_SET_OR_CLEAR(x, PCRE_UNGREEDY); - } - - bool utf8() const { - return PCRE_IS_SET(PCRE_UTF8); - } - RE_Options &set_utf8(bool x) { - PCRE_SET_OR_CLEAR(x, PCRE_UTF8); - } - - bool no_auto_capture() const { - return PCRE_IS_SET(PCRE_NO_AUTO_CAPTURE); - } - RE_Options &set_no_auto_capture(bool x) { - PCRE_SET_OR_CLEAR(x, PCRE_NO_AUTO_CAPTURE); - } - - RE_Options &set_all_options(int opt) { - all_options_ = opt; - return *this; - } - int all_options() const { - return all_options_ ; - } - - // TODO: add other pcre flags - - private: - int match_limit_; - int match_limit_recursion_; - int all_options_; -}; - -// These functions return some common RE_Options -static inline RE_Options UTF8() { - return RE_Options().set_utf8(true); -} - -static inline RE_Options CASELESS() { - return RE_Options().set_caseless(true); -} -static inline RE_Options MULTILINE() { - return RE_Options().set_multiline(true); -} - -static inline RE_Options DOTALL() { - return RE_Options().set_dotall(true); -} - -static inline RE_Options EXTENDED() { - return RE_Options().set_extended(true); -} - -// Interface for regular expression matching.

- AngelsHolocaust 4-11-04 updated to use version v5.0
- (INFO: this is regex-directed, NFA)
- AH: 9-11-04 - pcre_free: removed var, pcre already gives the ptr, now
- everything works as it should (no more crashes)
- -> removed CheckRegExp because pcre handles errors perfectly
- 10-11-04 - added pcError (errorhandling), pcInit
- 13-11-04 - removed the ErrorPos = 0 check -> always print erroroffset
- 17-10-05 - support for \1-\9 backreferences in TpcRegExp.GetReplStr
- 17-02-06 - added RunTimeOptions: caller can set options while searching
- 19-02-06 - added SearchOfs(): let PCRE use the complete string and offset
- into the string itself
- 20-12-06 - support for version 7.0
- 27.08.08 - support for v7.7
