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.

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 JIT compiler now supports partial matching and the (*MARK) and + (*COMMIT) verbs. + +. PCRE_INFO_MAXLOOKBEHIND can be used to find the longest lookbehing in a + pattern. + +.

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.

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) Also ensure that you have the following file, which is #included as source - when building a debugging version of PCRE, and is also used by pcretest. - - pcre_printint.src - - (6) 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_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_info.c - pcre_maketables.c - pcre_newline.c - pcre_ord2utf8.c - pcre_refcount.c - pcre_study.c - pcre_tables.c - pcre_try_flipped.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. - - (7) Now link all the compiled code into an object library in whichever form - your system keeps such libraries. This is the basic PCRE C library. If - your system has static and shared libraries, you may have to do this once - for each type. - - (8) Similarly, if you want to build the POSIX wrapper functions, 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. - - (9) Compile the test program pcretest.c (again, don't forget -DHAVE_CONFIG_H). - This needs the functions in the PCRE library when linking. It also needs - the pcreposix wrapper functions unless you compile it with -DNOPOSIX. The - pcretest.c program also needs the pcre_printint.src source file, which it - #includes. - -(10) Run pcretest on the testinput files in the testdata directory, and check - that the output matches the corresponding testoutput files. 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. - -(11) If you want to use the pcregrep command, compile and link pcregrep.c; it - uses only the basic PCRE library (it does not need the pcreposix library). - - -THE C++ WRAPPER FUNCTIONS - -The PCRE distribution also contains some C++ wrapper functions and tests, -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 WITH CMAKE" below) - -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. However, the tests are not run -automatically when CMake is used. - -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 like 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. It may be necessary to change the line -terminators in order 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 the -traditional Unix "configure". CMake creates project files (make files, solution -files, etc.) tailored to numerous development environments, including Visual -Studio, Borland, Msys, MinGW, NMake, and Unix. The following instructions -were contributed by a PCRE user. - -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. - -3. Create a new, empty build directory, for example C:\pcre\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++. - -5. Enter C:\pcre\pcre-xx and C:\pcre\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.

However, when using the traditional - matching function, PCRE uses recursion to handle subpatterns and indef- - inite repetition. This means that the available stack space may limit - the size of a subject string that can be processed by certain patterns. - For a discussion of stack issues, see the pcrestack documentation. +PCRE(3) PCRE(3) -UTF-8 AND UNICODE PROPERTY SUPPORT - From release 3.3, PCRE has had some support for character strings - encoded in the UTF-8 format. For release 4.0 this was greatly extended - to cover most common requirements, and in release 5.0 additional sup- - port for Unicode general category properties was added. +NAME + PCRE - Perl-compatible regular expressions - In order process UTF-8 strings, you must build PCRE to include UTF-8 - support in the code, and, in addition, you must call pcre_compile() - with the PCRE_UTF8 option flag, or the pattern must start with the - sequence (*UTF8). When either of these is the case, both the pattern - and any subject strings that are matched against it are treated as - UTF-8 strings instead of strings of 1-byte characters. + #include <pcre.h> - If you compile PCRE with UTF-8 support, but do not use it at run time, - the library will be a bit bigger, but the additional run time overhead - is limited to testing the PCRE_UTF8 flag occasionally, so should not be - very big. - If PCRE is built with Unicode character property support (which implies - UTF-8 support), the escape sequences \p{..}, \P{..}, and \X are sup- - ported. The available properties that can be tested are limited to the - general category properties such as Lu for an upper case letter or Nd - for a decimal number, the Unicode script names such as Arabic or Han, - and the derived properties Any and L&. A full list is given in the - pcrepattern documentation. Only the short names for properties are sup- - ported. For example, \p{L} matches a letter. Its Perl synonym, \p{Let- - ter}, is not supported. Furthermore, in Perl, many properties may - optionally be prefixed by "Is", for compatibility with Perl 5.6. PCRE - does not support this. +PCRE 16-BIT API BASIC FUNCTIONS - Validity of UTF-8 strings + pcre16 *pcre16_compile(PCRE_SPTR16 pattern, int options, + const char **errptr, int *erroffset, + const unsigned char *tableptr); - When you set the PCRE_UTF8 flag, the strings passed as patterns and - subjects are (by default) checked for validity on entry to the relevant - functions. From release 7.3 of PCRE, the check is according the rules - of RFC 3629, which are themselves derived from the Unicode specifica- - tion. Earlier releases of PCRE followed the rules of RFC 2279, which - allows the full range of 31-bit values (0 to 0x7FFFFFFF). The current - check allows only values in the range U+0 to U+10FFFF, excluding U+D800 - to U+DFFF. - - The excluded code points are the "Low Surrogate Area" of Unicode, of - which the Unicode Standard says this: "The Low Surrogate Area does not - contain any character assignments, consequently no character code - charts or namelists are provided for this area. Surrogates are reserved - for use with UTF-16 and then must be used in pairs." The code points - that are encoded by UTF-16 pairs are available as independent code - points in the UTF-8 encoding. (In other words, the whole surrogate - thing is a fudge for UTF-16 which unfortunately messes up UTF-8.) - - If an invalid UTF-8 string is passed to PCRE, an error return - (PCRE_ERROR_BADUTF8) is given. In some situations, you may already know - that your strings are valid, and therefore want to skip these checks in - order to improve performance. If you set the PCRE_NO_UTF8_CHECK flag at - compile time or at run time, PCRE assumes that the pattern or subject - it is given (respectively) contains only valid UTF-8 codes. In this - case, it does not diagnose an invalid UTF-8 string. + pcre16 *pcre16_compile2(PCRE_SPTR16 pattern, int options, + int *errorcodeptr, + const char **errptr, int *erroffset, + const unsigned char *tableptr); - If you pass an invalid UTF-8 string when PCRE_NO_UTF8_CHECK is set, - what happens depends on why the string is invalid. If the string con- - forms to the "old" definition of UTF-8 (RFC 2279), it is processed as a - string of characters in the range 0 to 0x7FFFFFFF. In other words, - apart from the initial validity test, PCRE (when in UTF-8 mode) handles - strings according to the more liberal rules of RFC 2279. However, if - the string does not even conform to RFC 2279, the result is undefined. - Your program may crash. + pcre16_extra *pcre16_study(const pcre16 *code, int options, + const char **errptr); - If you want to process strings of values in the full range 0 to - 0x7FFFFFFF, encoded in a UTF-8-like manner as per the old RFC, you can - set PCRE_NO_UTF8_CHECK to bypass the more restrictive test. However, in - this situation, you will have to apply your own validity check. + void pcre16_free_study(pcre16_extra *extra); - General comments about UTF-8 mode + int pcre16_exec(const pcre16 *code, const pcre16_extra *extra, + PCRE_SPTR16 subject, int length, int startoffset, + int options, int *ovector, int ovecsize); - 1.

Octal numbers up to \777 are recognized, and match two-byte UTF-8 - characters for values greater than \177. - 3. Repeat quantifiers apply to complete UTF-8 characters, not to indi- - vidual bytes, for example: \x{100}{3}. +PCRE 16-BIT API STRING EXTRACTION FUNCTIONS - 4.

The escape sequence \C can be used to match a single byte in UTF-8 - mode, but its use can lead to some strange effects.

The character escapes \b, \B, \d, \D, \s, \S, \w, and \W correctly - test characters of any code value, but, by default, the characters that - PCRE recognizes as digits, spaces, or word characters remain the same - set as before, all with values less than 256. This remains true even - when PCRE is built to include Unicode property support, because to do - otherwise would slow down PCRE in many common cases. Note in particular - that this applies to \b and \B, because they are defined in terms of \w - and \W. If you really want to test for a wider sense of, say, "digit", - you can use explicit Unicode property tests such as \p{Nd}. Alterna- - tively, if you set the PCRE_UCP option, the way that the character - escapes work is changed so that Unicode properties are used to deter- - mine which characters match. There are more details in the section on - generic character types in the pcrepattern documentation. + int pcre16_get_named_substring(const pcre16 *code, + PCRE_SPTR16 subject, int *ovector, + int stringcount, PCRE_SPTR16 stringname, + PCRE_SPTR16 *stringptr); - 7.

Case-insensitive matching applies only to characters whose values - are less than 128, unless PCRE is built with Unicode property support. - Even when Unicode property support is available, PCRE still uses its - own character tables when checking the case of low-valued characters, - so as not to degrade performance. The Unicode property information is - used only for characters with higher values. Furthermore, PCRE supports - case-insensitive matching only when there is a one-to-one mapping - between a letter's cases.

The majority of the + work to make this possible was done by Zoltan Herczeg. The two + libraries contain identical sets of functions, used in exactly the same + way. Only the names of the functions and the data types of their argu- + ments and results are different. To avoid over-complication and reduce + the documentation maintenance load, most of the PCRE documentation + describes the 8-bit library, with only occasional references to the + 16-bit library. This page describes what is different when you use the + 16-bit library. + + WARNING: A single application can be linked with both libraries, but + you must take care when processing any particular pattern to use func- + tions from just one library. For example, if you want to study a pat- + tern that was compiled with pcre16_compile(), you must do so with + pcre16_study(), not pcre_study(), and you must free the study data with + pcre16_free_study(). + + +THE HEADER FILE + + There is only one header file, pcre.h. It contains prototypes for all + the functions in both libraries, as well as definitions of flags, + structures, error codes, etc. + + +THE LIBRARY NAME + + In Unix-like systems, the 16-bit library is called libpcre16, and can + normally be accesss by adding -lpcre16 to the command for linking an + application that uses PCRE. + + +STRING TYPES + + In the 8-bit library, strings are passed to PCRE library functions as + vectors of bytes with the C type "char *". In the 16-bit library, + strings are passed as vectors of unsigned 16-bit quantities. The macro + PCRE_UCHAR16 specifies an appropriate data type, and PCRE_SPTR16 is + defined as "const PCRE_UCHAR16 *". In very many environments, "short + int" is a 16-bit data type. When PCRE is built, it defines PCRE_UCHAR16 + as "short int", but checks that it really is a 16-bit data type. If it + is not, the build fails with an error message telling the maintainer to + modify the definition appropriately. + + +STRUCTURE TYPES + + The types of the opaque structures that are used for compiled 16-bit + patterns and JIT stacks are pcre16 and pcre16_jit_stack respectively. + The type of the user-accessible structure that is returned by + pcre16_study() is pcre16_extra, and the type of the structure that is + used for passing data to a callout function is pcre16_callout_block. + These structures contain the same fields, with the same names, as their + 8-bit counterparts. The only difference is that pointers to character + strings are 16-bit instead of 8-bit types. + + +16-BIT FUNCTIONS + + For every function in the 8-bit library there is a corresponding func- + tion in the 16-bit library with a name that starts with pcre16_ instead + of pcre_. The prototypes are listed above. In addition, there is one + extra function, pcre16_utf16_to_host_byte_order(). This is a utility + function that converts a UTF-16 character string to host byte order if + necessary. The other 16-bit functions expect the strings they are + passed to be in host byte order. + + The input and output arguments of pcre16_utf16_to_host_byte_order() may + point to the same address, that is, conversion in place is supported. + The output buffer must be at least as long as the input. + + The length argument specifies the number of 16-bit data units in the + input string; a negative value specifies a zero-terminated string. + + If byte_order is NULL, it is assumed that the string starts off in host + byte order. This may be changed by byte-order marks (BOMs) anywhere in + the string (commonly as the first character). + + If byte_order is not NULL, a non-zero value of the integer to which it + points means that the input starts off in host byte order, otherwise + the opposite order is assumed. Again, BOMs in the string can change + this. The final byte order is passed back at the end of processing. + + If keep_boms is not zero, byte-order mark characters (0xfeff) are + copied into the output string. Otherwise they are discarded. + + The result of the function is the number of 16-bit units placed into + the output buffer, including the zero terminator if the string was + zero-terminated. + + +SUBJECT STRING OFFSETS + + The offsets within subject strings that are returned by the matching + functions are in 16-bit units rather than bytes. + + +NAMED SUBPATTERNS + + The name-to-number translation table that is maintained for named sub- + patterns uses 16-bit characters. The pcre16_get_stringtable_entries() + function returns the length of each entry in the table as the number of + 16-bit data units. + + +OPTION NAMES + + There are two new general option names, PCRE_UTF16 and + PCRE_NO_UTF16_CHECK, which correspond to PCRE_UTF8 and + PCRE_NO_UTF8_CHECK in the 8-bit library. In fact, these new options + define the same bits in the options word. There is a discussion about + the validity of UTF-16 strings in the pcreunicode page. + + For the pcre16_config() function there is an option PCRE_CONFIG_UTF16 + that returns 1 if UTF-16 support is configured, otherwise 0. If this + option is given to pcre_config(), or if the PCRE_CONFIG_UTF8 option is + given to pcre16_config(), the result is the PCRE_ERROR_BADOPTION error. + + +CHARACTER CODES + + In 16-bit mode, when PCRE_UTF16 is not set, character values are + treated in the same way as in 8-bit, non UTF-8 mode, except, of course, + that they can range from 0 to 0xffff instead of 0 to 0xff. Character + types for characters less than 0xff can therefore be influenced by the + locale in the same way as before. Characters greater than 0xff have + only one case, and no "type" (such as letter or digit). + + In UTF-16 mode, the character code is Unicode, in the range 0 to + 0x10ffff, with the exception of values in the range 0xd800 to 0xdfff + because those are "surrogate" values that are used in pairs to encode + values greater than 0xffff. + + A UTF-16 string can indicate its endianness by special code knows as a + byte-order mark (BOM). The PCRE functions do not handle this, expecting + strings to be in host byte order. A utility function called + pcre16_utf16_to_host_byte_order() is provided to help with this (see + above). + + +ERROR NAMES + + The errors PCRE_ERROR_BADUTF16_OFFSET and PCRE_ERROR_SHORTUTF16 corre- + spond to their 8-bit counterparts. The error PCRE_ERROR_BADMODE is + given when a compiled pattern is passed to a function that processes + patterns in the other mode, for example, if a pattern compiled with + pcre_compile() is passed to pcre16_exec(). + + There are new error codes whose names begin with PCRE_UTF16_ERR for + invalid UTF-16 strings, corresponding to the PCRE_UTF8_ERR codes for + UTF-8 strings that are described in the section entitled "Reason codes + for invalid UTF-8 strings" in the main pcreapi page. The UTF-16 errors + are: + + PCRE_UTF16_ERR1 Missing low surrogate at end of string + PCRE_UTF16_ERR2 Invalid low surrogate follows high surrogate + PCRE_UTF16_ERR3 Isolated low surrogate + PCRE_UTF16_ERR4 Invalid character 0xfffe + + +ERROR TEXTS + + If there is an error while compiling a pattern, the error text that is + passed back by pcre16_compile() or pcre16_compile2() is still an 8-bit + character string, zero-terminated. + + +CALLOUTS + + The subject and mark fields in the callout block that is passed to a + callout function point to 16-bit vectors. + + +TESTING + + The pcretest program continues to operate with 8-bit input and output + files, but it can be used for testing the 16-bit library. If it is run + with the command line option -16, patterns and subject strings are con- + verted from 8-bit to 16-bit before being passed to PCRE, and the 16-bit + library functions are used instead of the 8-bit ones. Returned 16-bit + strings are converted to 8-bit for output. If the 8-bit library was not + compiled, pcretest defaults to 16-bit and the -16 option is ignored. + + When PCRE is being built, the RunTest script that is called by "make + check" uses the pcretest -C option to discover which of the 8-bit and + 16-bit libraries has been built, and runs the tests appropriately. + + +NOT SUPPORTED IN 16-BIT MODE + + Not all the features of the 8-bit library are available with the 16-bit + library.

When either of these is the case, both the pattern and any + subject strings that are matched against it are treated as UTF-8 + strings instead of strings of 1-byte characters. + + +UTF-16 SUPPORT + + In order process UTF-16 strings, you must build PCRE's 16-bit library + with UTF support, and, in addition, you must call pcre16_compile() with + the PCRE_UTF16 option flag, or the pattern must start with the sequence + (*UTF16). When either of these is the case, both the pattern and any + subject strings that are matched against it are treated as UTF-16 + strings instead of strings of 16-bit characters. + + +UTF SUPPORT OVERHEAD + + If you compile PCRE with UTF support, but do not use it at run time, + the library will be a bit bigger, but the additional run time overhead + is limited to testing the PCRE_UTF8/16 flag occasionally, so should not + be very big. + + +UNICODE PROPERTY SUPPORT + + If PCRE is built with Unicode character property support (which implies + UTF support), the escape sequences \p{..}, \P{..}, and \X can be used. + The available properties that can be tested are limited to the general + category properties such as Lu for an upper case letter or Nd for a + decimal number, the Unicode script names such as Arabic or Han, and the + derived properties Any and L&. A full list is given in the pcrepattern + documentation. Only the short names for properties are supported. For + example, \p{L} matches a letter. Its Perl synonym, \p{Letter}, is not + supported. Furthermore, in Perl, many properties may optionally be + prefixed by "Is", for compatibility with Perl 5.6. PCRE does not sup- + port this. + + Validity of UTF-8 strings + + When you set the PCRE_UTF8 flag, the byte strings passed as patterns + and subjects are (by default) checked for validity on entry to the rel- + evant functions. The entire string is checked before any other process- + ing takes place. From release 7.3 of PCRE, the check is according the + rules of RFC 3629, which are themselves derived from the Unicode speci- + fication. Earlier releases of PCRE followed the rules of RFC 2279, + which allows the full range of 31-bit values (0 to 0x7FFFFFFF). The + current check allows only values in the range U+0 to U+10FFFF, exclud- + ing U+D800 to U+DFFF. + + The excluded code points are the "Surrogate Area" of Unicode. They are + reserved for use by UTF-16, where they are used in pairs to encode + codepoints with values greater than 0xFFFF. The code points that are + encoded by UTF-16 pairs are available independently in the UTF-8 encod- + ing. (In other words, the whole surrogate thing is a fudge for UTF-16 + which unfortunately messes up UTF-8.) + + If an invalid UTF-8 string is passed to PCRE, an error return is given. + At compile time, the only additional information is the offset to the + first byte of the failing character. The run-time functions pcre_exec() + and pcre_dfa_exec() also pass back this information, as well as a more + detailed reason code if the caller has provided memory in which to do + this. + + In some situations, you may already know that your strings are valid, + and therefore want to skip these checks in order to improve perfor- + mance, for example in the case of a long subject string that is being + scanned repeatedly with different patterns. If you set the + PCRE_NO_UTF8_CHECK flag at compile time or at run time, PCRE assumes + that the pattern or subject it is given (respectively) contains only + valid UTF-8 codes. In this case, it does not diagnose an invalid UTF-8 + string. + + If you pass an invalid UTF-8 string when PCRE_NO_UTF8_CHECK is set, + what happens depends on why the string is invalid. If the string con- + forms to the "old" definition of UTF-8 (RFC 2279), it is processed as a + string of characters in the range 0 to 0x7FFFFFFF by pcre_dfa_exec() + and the interpreted version of pcre_exec(). In other words, apart from + the initial validity test, these functions (when in UTF-8 mode) handle + strings according to the more liberal rules of RFC 2279. However, the + just-in-time (JIT) optimization for pcre_exec() supports only RFC 3629. + If you are using JIT optimization, or if the string does not even con- + form to RFC 2279, the result is undefined. Your program may crash. + + If you want to process strings of values in the full range 0 to + 0x7FFFFFFF, encoded in a UTF-8-like manner as per the old RFC, you can + set PCRE_NO_UTF8_CHECK to bypass the more restrictive test. However, in + this situation, you will have to apply your own validity check, and + avoid the use of JIT optimization. + + Validity of UTF-16 strings + + When you set the PCRE_UTF16 flag, the strings of 16-bit data units that + are passed as patterns and subjects are (by default) checked for valid- + ity on entry to the relevant functions. Values other than those in the + surrogate range U+D800 to U+DFFF are independent code points. Values in + the surrogate range must be used in pairs in the correct manner. + + If an invalid UTF-16 string is passed to PCRE, an error return is + given. At compile time, the only additional information is the offset + to the first data unit of the failing character. The run-time functions + pcre16_exec() and pcre16_dfa_exec() also pass back this information, as + well as a more detailed reason code if the caller has provided memory + in which to do this. + + In some situations, you may already know that your strings are valid, + and therefore want to skip these checks in order to improve perfor- + mance. If you set the PCRE_NO_UTF16_CHECK flag at compile time or at + run time, PCRE assumes that the pattern or subject it is given (respec- + tively) contains only valid UTF-16 sequences. In this case, it does not + diagnose an invalid UTF-16 string. + + General comments about UTF modes + + 1. Codepoints less than 256 can be specified by either braced or + unbraced hexadecimal escape sequences (for example, \x{b3} or \xb3). + Larger values have to use braced sequences. + + 2. Octal numbers up to \777 are recognized, and in UTF-8 mode, they + match two-byte characters for values greater than \177. + + 3. Repeat quantifiers apply to complete UTF characters, not to individ- + ual data units, for example: \x{100}{3}. + + 4. The dot metacharacter matches one UTF character instead of a single + data unit. + + 5. The escape sequence \C can be used to match a single byte in UTF-8 + mode, or a single 16-bit data unit in UTF-16 mode, but its use can lead + to some strange effects because it breaks up multi-unit characters (see + the description of \C in the pcrepattern documentation). The use of \C + is not supported in the alternative matching function + pcre[16]_dfa_exec(), nor is it supported in UTF mode by the JIT opti- + mization of pcre[16]_exec(). If JIT optimization is requested for a UTF + pattern that contains \C, it will not succeed, and so the matching will + be carried out by the normal interpretive function. + + 6. The character escapes \b, \B, \d, \D, \s, \S, \w, and \W correctly + test characters of any code value, but, by default, the characters that + PCRE recognizes as digits, spaces, or word characters remain the same + set as in non-UTF mode, all with values less than 256. This remains + true even when PCRE is built to include Unicode property support, + because to do otherwise would slow down PCRE in many common cases. Note + in particular that this applies to \b and \B, because they are defined + in terms of \w and \W. If you really want to test for a wider sense of, + say, "digit", you can use explicit Unicode property tests such as + \p{Nd}. Alternatively, if you set the PCRE_UCP option, the way that the + character escapes work is changed so that Unicode properties are used + to determine which characters match. There are more details in the sec- + tion on generic character types in the pcrepattern documentation. + + 7. Similarly, characters that match the POSIX named character classes + are all low-valued characters, unless the PCRE_UCP option is set. + + 8. However, the horizontal and vertical white space matching escapes + (\h, \H, \v, and \V) do match all the appropriate Unicode characters, + whether or not PCRE_UCP is set. + + 9. Case-insensitive matching applies only to characters whose values + are less than 128, unless PCRE is built with Unicode property support. + Even when Unicode property support is available, PCRE still uses its + own character tables when checking the case of low-valued characters, + so as not to degrade performance. The Unicode property information is + used only for characters with higher values. Furthermore, PCRE supports + case-insensitive matching only when there is a one-to-one mapping + between a letter's cases. There are a small number of many-to-one map- + pings in Unicode; these are not supported by PCRE. + + +AUTHOR + + Philip Hazel + University Computing Service + Cambridge CB2 3QH, England. + + +REVISION + + Last updated: 14 April 2012 + Copyright (c) 1997-2012 University of Cambridge. +------------------------------------------------------------------------------ + + +PCREJIT(3) PCREJIT(3) + + +NAME + PCRE - Perl-compatible regular expressions + + +PCRE JUST-IN-TIME COMPILER SUPPORT + + Just-in-time compiling is a heavyweight optimization that can greatly + speed up pattern matching. However, it comes at the cost of extra pro- + cessing before the match is performed. Therefore, it is of most benefit + when the same pattern is going to be matched many times. This does not + necessarily mean many calls of a matching function; if the pattern is + not anchored, matching attempts may take place many times at various + positions in the subject, even for a single call. Therefore, if the + subject string is very long, it may still pay to use JIT for one-off + matches. + + JIT support applies only to the traditional Perl-compatible matching + function. It does not apply when the DFA matching function is being + used. The code for this support was written by Zoltan Herczeg. + + +8-BIT and 16-BIT SUPPORT + + JIT support is available for both the 8-bit and 16-bit PCRE libraries. + To keep this documentation simple, only the 8-bit interface is + described in what follows. If you are using the 16-bit library, substi- + tute the 16-bit functions and 16-bit structures (for example, + pcre16_jit_stack instead of pcre_jit_stack). + + +AVAILABILITY OF JIT SUPPORT + + JIT support is an optional feature of PCRE. The "configure" option + --enable-jit (or equivalent CMake option) must be set when PCRE is + built if you want to use JIT. The support is limited to the following + hardware platforms: + + ARM v5, v7, and Thumb2 + Intel x86 32-bit and 64-bit + MIPS 32-bit + Power PC 32-bit and 64-bit + + If --enable-jit is set on an unsupported platform, compilation fails. + + A program that is linked with PCRE 8.20 or later can tell if JIT sup- + port is available by calling pcre_config() with the PCRE_CONFIG_JIT + option. The result is 1 when JIT is available, and 0 otherwise. How- + ever, a simple program does not need to check this in order to use JIT. + The API is implemented in a way that falls back to the interpretive + code if JIT is not available. + + If your program may sometimes be linked with versions of PCRE that are + older than 8.20, but you want to use JIT when it is available, you can + test the values of PCRE_MAJOR and PCRE_MINOR, or the existence of a JIT + macro such as PCRE_CONFIG_JIT, for compile-time control of your code. + + +SIMPLE USE OF JIT + + You have to do two things to make use of the JIT support in the sim- + plest way: + + (1) Call pcre_study() with the PCRE_STUDY_JIT_COMPILE option for + each compiled pattern, and pass the resulting pcre_extra block to + pcre_exec(). + + (2) Use pcre_free_study() to free the pcre_extra block when it is + no longer needed, instead of just freeing it yourself. This + ensures that any JIT data is also freed. + + For a program that may be linked with pre-8.20 versions of PCRE, you + can insert + + #ifndef PCRE_STUDY_JIT_COMPILE + #define PCRE_STUDY_JIT_COMPILE 0 + #endif + + so that no option is passed to pcre_study(), and then use something + like this to free the study data: + + #ifdef PCRE_CONFIG_JIT + pcre_free_study(study_ptr); + #else + pcre_free(study_ptr); + #endif + + PCRE_STUDY_JIT_COMPILE requests the JIT compiler to generate code for + complete matches. If you want to run partial matches using the + PCRE_PARTIAL_HARD or PCRE_PARTIAL_SOFT options of pcre_exec(), you + should set one or both of the following options in addition to, or + instead of, PCRE_STUDY_JIT_COMPILE when you call pcre_study(): + + PCRE_STUDY_JIT_PARTIAL_HARD_COMPILE + PCRE_STUDY_JIT_PARTIAL_SOFT_COMPILE + + The JIT compiler generates different optimized code for each of the + three modes (normal, soft partial, hard partial). When pcre_exec() is + called, the appropriate code is run if it is available. Otherwise, the + pattern is matched using interpretive code. + + In some circumstances you may need to call additional functions. These + are described in the section entitled "Controlling the JIT stack" + below. + + If JIT support is not available, PCRE_STUDY_JIT_COMPILE etc. are + ignored, and no JIT data is created. Otherwise, the compiled pattern is + passed to the JIT compiler, which turns it into machine code that exe- + cutes much faster than the normal interpretive code. When pcre_exec() + is passed a pcre_extra block containing a pointer to JIT code of the + appropriate mode (normal or hard/soft partial), it obeys that code + instead of running the interpreter. The result is identical, but the + compiled JIT code runs much faster. + + There are some pcre_exec() options that are not supported for JIT exe- + cution. There are also some pattern items that JIT cannot handle. + Details are given below. In both cases, execution automatically falls + back to the interpretive code. If you want to know whether JIT was + actually used for a particular match, you should arrange for a JIT + callback function to be set up as described in the section entitled + "Controlling the JIT stack" below, even if you do not need to supply a + non-default JIT stack. Such a callback function is called whenever JIT + code is about to be obeyed. If the execution options are not right for + JIT execution, the callback function is not obeyed. + + If the JIT compiler finds an unsupported item, no JIT data is gener- + ated. You can find out if JIT execution is available after studying a + pattern by calling pcre_fullinfo() with the PCRE_INFO_JIT option. A + result of 1 means that JIT compilation was successful. A result of 0 + means that JIT support is not available, or the pattern was not studied + with PCRE_STUDY_JIT_COMPILE etc., or the JIT compiler was not able to + handle the pattern. + + Once a pattern has been studied, with or without JIT, it can be used as + many times as you like for matching different subject strings. + + +UNSUPPORTED OPTIONS AND PATTERN ITEMS + + The only pcre_exec() options that are supported for JIT execution are + PCRE_NO_UTF8_CHECK, PCRE_NO_UTF16_CHECK, PCRE_NOTBOL, PCRE_NOTEOL, + PCRE_NOTEMPTY, PCRE_NOTEMPTY_ATSTART, PCRE_PARTIAL_HARD, and PCRE_PAR- + TIAL_SOFT. + + The unsupported pattern items are: + + \C match a single byte; not supported in UTF-8 mode + (?Cn) callouts + (*PRUNE) ) + (*SKIP) ) backtracking control verbs + (*THEN) ) + + Support for some of these may be added in future. + + +RETURN VALUES FROM JIT EXECUTION + + When a pattern is matched using JIT execution, the return values are + the same as those given by the interpretive pcre_exec() code, with the + addition of one new error code: PCRE_ERROR_JIT_STACKLIMIT. This means + that the memory used for the JIT stack was insufficient. See "Control- + ling the JIT stack" below for a discussion of JIT stack usage. For com- + patibility with the interpretive pcre_exec() code, no more than two- + thirds of the ovector argument is used for passing back captured sub- + strings. + + The error code PCRE_ERROR_MATCHLIMIT is returned by the JIT code if + searching a very large pattern tree goes on for too long, as it is in + the same circumstance when JIT is not used, but the details of exactly + what is counted are not the same. The PCRE_ERROR_RECURSIONLIMIT error + code is never returned by JIT execution. + + +SAVING AND RESTORING COMPILED PATTERNS + + The code that is generated by the JIT compiler is architecture-spe- + cific, and is also position dependent. For those reasons it cannot be + saved (in a file or database) and restored later like the bytecode and + other data of a compiled pattern. Saving and restoring compiled pat- + terns is not something many people do. More detail about this facility + is given in the pcreprecompile documentation. It should be possible to + run pcre_study() on a saved and restored pattern, and thereby recreate + the JIT data, but because JIT compilation uses significant resources, + it is probably not worth doing this; you might as well recompile the + original pattern. + + +CONTROLLING THE JIT STACK + + When the compiled JIT code runs, it needs a block of memory to use as a + stack. By default, it uses 32K on the machine stack. However, some + large or complicated patterns need more than this. The error + PCRE_ERROR_JIT_STACKLIMIT is given when there is not enough stack. + Three functions are provided for managing blocks of memory for use as + JIT stacks. There is further discussion about the use of JIT stacks in + the section entitled "JIT stack FAQ" below. + + The pcre_jit_stack_alloc() function creates a JIT stack. Its arguments + are a starting size and a maximum size, and it returns a pointer to an + opaque structure of type pcre_jit_stack, or NULL if there is an error. + The pcre_jit_stack_free() function can be used to free a stack that is + no longer needed. (For the technically minded: the address space is + allocated by mmap or VirtualAlloc.) + + JIT uses far less memory for recursion than the interpretive code, and + a maximum stack size of 512K to 1M should be more than enough for any + pattern. + + The pcre_assign_jit_stack() function specifies which stack JIT code + should use. Its arguments are as follows: + + pcre_extra *extra + pcre_jit_callback callback + void *data + + The extra argument must be the result of studying a pattern with + PCRE_STUDY_JIT_COMPILE etc. There are three cases for the values of the + other two options: + + (1) If callback is NULL and data is NULL, an internal 32K block + on the machine stack is used. + + (2) If callback is NULL and data is not NULL, data must be + a valid JIT stack, the result of calling pcre_jit_stack_alloc(). + + (3) If callback is not NULL, it must point to a function that is + called with data as an argument at the start of matching, in + order to set up a JIT stack. If the return from the callback + function is NULL, the internal 32K stack is used; otherwise the + return value must be a valid JIT stack, the result of calling + pcre_jit_stack_alloc(). + + A callback function is obeyed whenever JIT code is about to be run; it + is not obeyed when pcre_exec() is called with options that are incom- + patible for JIT execution. A callback function can therefore be used to + determine whether a match operation was executed by JIT or by the + interpreter. + + You may safely use the same JIT stack for more than one pattern (either + by assigning directly or by callback), as long as the patterns are all + matched sequentially in the same thread. In a multithread application, + if you do not specify a JIT stack, or if you assign or pass back NULL + from a callback, that is thread-safe, because each thread has its own + machine stack. However, if you assign or pass back a non-NULL JIT + stack, this must be a different stack for each thread so that the + application is thread-safe. + + Strictly speaking, even more is allowed. You can assign the same non- + NULL stack to any number of patterns as long as they are not used for + matching by multiple threads at the same time. For example, you can + assign the same stack to all compiled patterns, and use a global mutex + in the callback to wait until the stack is available for use. However, + this is an inefficient solution, and not recommended. + + This is a suggestion for how a multithreaded program that needs to set + up non-default JIT stacks might operate: + + During thread initalization + thread_local_var = pcre_jit_stack_alloc(...) + + During thread exit + pcre_jit_stack_free(thread_local_var) + + Use a one-line callback function + return thread_local_var + + All the functions described in this section do nothing if JIT is not + available, and pcre_assign_jit_stack() does nothing unless the extra + argument is non-NULL and points to a pcre_extra block that is the + result of a successful study with PCRE_STUDY_JIT_COMPILE etc. + + +JIT STACK FAQ + + (1) Why do we need JIT stacks? + + PCRE (and JIT) is a recursive, depth-first engine, so it needs a stack + where the local data of the current node is pushed before checking its + child nodes. Allocating real machine stack on some platforms is diffi- + cult. For example, the stack chain needs to be updated every time if we + extend the stack on PowerPC. Although it is possible, its updating + time overhead decreases performance. So we do the recursion in memory. + + (2) Why don't we simply allocate blocks of memory with malloc()? + + Modern operating systems have a nice feature: they can reserve an + address space instead of allocating memory. We can safely allocate mem- + ory pages inside this address space, so the stack could grow without + moving memory data (this is important because of pointers). Thus we can + allocate 1M address space, and use only a single memory page (usually + 4K) if that is enough. However, we can still grow up to 1M anytime if + needed. + + (3) Who "owns" a JIT stack? + + The owner of the stack is the user program, not the JIT studied pattern + or anything else. The user program must ensure that if a stack is used + by pcre_exec(), (that is, it is assigned to the pattern currently run- + ning), that stack must not be used by any other threads (to avoid over- + writing the same memory area). The best practice for multithreaded pro- + grams is to allocate a stack for each thread, and return this stack + through the JIT callback function. + + (4) When should a JIT stack be freed? + + You can free a JIT stack at any time, as long as it will not be used by + pcre_exec() again. When you assign the stack to a pattern, only a + pointer is set. There is no reference counting or any other magic. You + can free the patterns and stacks in any order, anytime. Just do not + call pcre_exec() with a pattern pointing to an already freed stack, as + that will cause SEGFAULT. (Also, do not free a stack currently used by + pcre_exec() in another thread). You can also replace the stack for a + pattern at any time. You can even free the previous stack before + assigning a replacement. + + (5) Should I allocate/free a stack every time before/after calling + pcre_exec()? + + No, because this is too costly in terms of resources. However, you + could implement some clever idea which release the stack if it is not + used in let's say two minutes. The JIT callback can help to achive this + without keeping a list of the currently JIT studied patterns. + + (6) OK, the stack is for long term memory allocation. But what happens + if a pattern causes stack overflow with a stack of 1M? Is that 1M kept + until the stack is freed? + + Especially on embedded sytems, it might be a good idea to release mem- + ory sometimes without freeing the stack. There is no API for this at + the moment. Probably a function call which returns with the currently + allocated memory for any stack and another which allows releasing mem- + ory (shrinking the stack) would be a good idea if someone needs this. + + (7) This is too much of a headache. Isn't there any better solution for + JIT stack handling? + + No, thanks to Windows. If POSIX threads were used everywhere, we could + throw out this complicated API. + + +EXAMPLE CODE + + This is a single-threaded example that specifies a JIT stack without + using a callback. + + int rc; + int ovector[30]; + pcre *re; + pcre_extra *extra; + pcre_jit_stack *jit_stack; + + re = pcre_compile(pattern, 0, &error, &erroffset, NULL); + /* Check for errors */ + extra = pcre_study(re, PCRE_STUDY_JIT_COMPILE, &error); + jit_stack = pcre_jit_stack_alloc(32*1024, 512*1024); + /* Check for error (NULL) */ + pcre_assign_jit_stack(extra, NULL, jit_stack); + rc = pcre_exec(re, extra, subject, length, 0, 0, ovector, 30); + /* Check results */ + pcre_free(re); + pcre_free_study(extra); + pcre_jit_stack_free(jit_stack); + + +SEE ALSO + + pcreapi(3) + + +AUTHOR + + Philip Hazel (FAQ by Zoltan Herczeg) + University Computing Service + Cambridge CB2 3QH, England. + + +REVISION + + Last updated: 04 May 2012 + Copyright (c) 1997-2012 University of Cambridge. ------------------------------------------------------------------------------ @@ -6075,11 +7473,11 @@ NAME PARTIAL MATCHING IN PCRE - In normal use of PCRE, if the subject string that is passed to - pcre_exec() or pcre_dfa_exec() matches as far as it goes, but is too - short to match the entire pattern, PCRE_ERROR_NOMATCH is returned. - There are circumstances where it might be helpful to distinguish this - case from other cases in which there is no match. + In normal use of PCRE, if the subject string that is passed to a match- + ing function matches as far as it goes, but is too short to match the + entire pattern, PCRE_ERROR_NOMATCH is returned.
