* op.c: Add debugging dump functionKarl Williamson2019-11-065-4/+53
| | | | This function dumps out an inversion map
* op.h: Add synonyms for some tr/// valuesKarl Williamson2019-11-061-0/+3
|
* Change names of some OPpTRANS flagsKarl Williamson2019-11-064-92/+97
| | | | | | | These two flags will shortly become obsolete, replaced by ones with different meanings. This flag makes the new ones the normal ones, and makes the old names synonyms so that code that refers to them can compile.
* doop.c: Refactor do_trans_complex()Karl Williamson2019-11-062-14/+27
| | | | | | | I had trouble understanding how this uncommented routine worked. And it turned out to be broken, squeezing the pre-transliterated characters instead of the post-transliterated ones. This fixes the TODO test added in the previous commit.
* t/op/tr.t: Add tests, incl. a TODOKarl Williamson2019-11-061-10/+46
| | | | | | | | This adds a TODO test which demonstrates that the current tr/// is broken, to be fixed by the next commit. It adds other tests designed to stress the forthcoming revisions in the implementation of tr///.
* doop.c: Change name of variableKarl Williamson2019-11-061-9/+9
| | | | This helped me understand what was going on in this function
* doop.c: Change out-of-bounds valueKarl Williamson2019-11-062-2/+3
| | | | | | This currently uses 0xfeedface as a marker for something that isn't a legal value. But that could in fact become legal at same point. This defines a value TR_OOB that can be guaranteed not to become legal.
* doop.c: Add, revise commentsKarl Williamson2019-11-061-16/+31
|
* op.c: Simplify expression.Karl Williamson2019-11-061-3/+2
| | | | | This also makes sure 'struct_size' has the correct value in it for any future uses.
* regen/ebcdic.pl: Add tables that partition by UTF-8 lengthKarl Williamson2019-11-062-1/+161
| | | | | These will be used in a future commit. This creates equivalence classes of ranges of code points whose UTF-8 representations are the same length
* op.c, doop.c Use mnemonics instead of numeric valuesKarl Williamson2019-11-063-22/+36
| | | | For legibility and maintainability
* doop.c: Add a parameter to a few fcnsKarl Williamson2019-11-064-30/+18
| | | | | instead of deriving it each time from inside the function. This is in preparation for future commits.
* Change macro name in tr/// codeKarl Williamson2019-11-063-18/+22
| | | | This makes it more mnemonic. Also add an explanation in toke.c
* op.c: Comments onlyKarl Williamson2019-11-061-3/+5
| | | | Indent for clarity, and add a comment
* doop.c, op.c: White-space onlyKarl Williamson2019-11-062-102/+103
| | | | Remove trailing blanks and outdent a doubly indented block
* op.c: Indent some codeKarl Williamson2019-11-061-102/+102
| | | | | This is in preparation for a future commit which will surround this with an 'if'.
* toke.c: comment, White-space onlyKarl Williamson2019-11-061-2/+3
| | | | Wrap a too-long line
* Allow core to work with code points above IV_MAXKarl Williamson2019-11-062-1/+7
| | | | | Higher has been reserved for core use, and a future commit will want to finally do this.
* Move some static fcns from regcomp.c to invlist_inline.hKarl Williamson2019-11-065-172/+185
| | | | | They are still only accessible from regcomp.c, but this is in preparation for them to be usable from other core files as well.
* regcomp.c: Change name of static function.Karl Williamson2019-11-064-11/+11
| | | | This removes an unnecessary leading underscore
* invlist_inline.h: White space onlyKarl Williamson2019-11-061-1/+5
| | | | Fold a too-long line
* invlist_inline.h: Restrict files symbols are inKarl Williamson2019-11-061-1/+1
| | | | These are only needed in regcomp.c, so restrict them to that file

* prevent a race between name-based stat and an open modifying atimeTony Cook2019-11-071-2/+4
| | | | | | | | | Most linux systems rarely update atime, so it's very unlikely for this issue to trigger there, but on a system with classic atime behaviour this was a race between open modifying atime and time() ticking over. gh #17234
* add defensive parensYves Orton2019-11-061-29/+29

* rework U8TOxx_LE macros to force unsigned accessYves Orton2019-11-061-17/+47
| | | | | | | | | This introduces a _shifted_octet() utility macro to make things more clear, it also adds support for USE_UNALIGNED_PTR_DEREF for little-endian platforms that allow unaligned access. This must be manually defined and ONLY affects little endian builds currently, and is there primarily for -g builds on x86 (eg for perl developers themselves).
* Fix the UTO*_LE macrosMatt Turner2019-11-051-6/+6
| | | | | | | | | | | Embarrassingly I got confused and swapped them (BYTEORDER == 0x1234 etc is not great...). Somehow the perl test suite still passes with this, but fortunately the test suite for modules like Algorithm-MinPerfHashTwoLevel caught the problem.

* Remove compiler in .travis.ymlSteve Peters2019-11-051-6/+0
| | | SInce `clang` was removed as a compiler option in the previous change to `.travis.yml`, no need to exclude Linux from using it. Also, no need for the excludes for OS X since was removed.

* gv.c: SVf needs to be surrounded by spacesKarl Williamson2019-11-051-2/+2
| | | | perl can be compiled with C++, and this is illegal there.
* Remove unused `key` and `orig_keyword` parameters from `yyl_key_core`Dagfinn Ilmari Mannsåker2019-11-051-3/+5
| | | | | They were only ever passed as zeros, so just make them local to the function.
* Rename `tmp` local to `key` in `yyl_keylookup`Dagfinn Ilmari Mannsåker2019-11-051-9/+9
| | | | Also only initialise it just before it's actually used.
* Remove unused `key` parameter from `yyl_just_a_word`Dagfinn Ilmari Mannsåker2019-11-051-13/+12

* t/re/speed.t: increase timeoutDavid Mitchell2019-11-051-1/+2
| | | | | | | Test 58 is supposed to finish in milliseconds, or take 10s of seconds if it hits the bug. It currently tests for <= 1s and is failing occasionally in smokes. Increase the timeout to 2s and see if the issue goes away. Also add a diag() to display the elapsed time on failure.

* [MERGE] Even smaller tokeAaron Crane2019-11-042-1767/+1789
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This continues the work merged in 5015bd0bb5ee7e0fa1ede1669bdfcd7bb5f10ebd, factoring code out of Perl_yylex() and its callees, in the hope of making the lexer easier to understand locally. The work in the previous branch used unbounded tail recursion in some places. Some compilers may have been able to compile the tail-recursive calls as jumps under some optimisation modes, but we cannot rely on that. So this further work replaces the unbounded recursion with gotos or other control structures. It's a little annoying not to have been able to eliminate those gotos, but these remaining gotos all occur within a function that's considerably smaller and easier to understand, and they merely jump all the way back to the top of that function. After these changes, the largest remaining piece of Perl_yylex() is just over 900 lines (down from originally >4100), and consists of a single switch statement, all of whose case groups are independent. This branch also contains a note in perldelta that this major refactoring has taken place. Closes #17220

| * toke.c: replace recursive calls to yyl_try() with gotoAaron Crane2019-11-041-15/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The downside of writing these calls recursively is that not all compilers will compile the tail-position calls as jumps; that's especially true in earlier versions of this refactoring process (where yyl_try() took a large number of arguments), but it's not in general something we can expect to happen — especially in the presence of `-O0` or similar compiler options. This can lead to call-stack overflow in some circumstances. Most recursive calls to yyl_try() occur within yyl_try() itself, so we can easily replace them with an explicit `goto` (which is what most compilers would use for the recursive calls anyway, now that yyl_try() takes ≤3 parameters). There are only two other recursive-call cases. One is yyl_fake_eof(), which as far as I can tell is never called repeatedly within a single file; this seems safe. The other is yyl_eol(). It has exactly two distinct return paths, so this commit moves the retry logic into its yyl_try() caller. With this change, we no longer seem to trigger call-stack overflow. Closes #17220

| * toke.c: don't pass around a copy of PL_parser->saw_infix_sigilAaron Crane2019-11-041-56/+65
| | | | | | | | | | | | | | | | | | | | | | | | There's exactly one place where we need to consult it (and that only for producing good error messages in a specific group of term-after-term situations). The reason for passing it around was so that it could be reset to false early on in the process of lexing a token, while then allowing the three separate cases that might need to set it true to do so independently. Instead, centralise the logic of determining when it needs to be true.

| |
| * toke.c: remove formbrack argument from yyl_try()Aaron Crane2019-11-041-23/+20
| | | | | | | | | | With this commit, yyl_try() has few enough arguments that the RETRY() macro no longer serves any useful purpose; delete it too.
| * toke.c: delete weird initial_state arg to yyl_try()Aaron Crane2019-11-041-20/+13
| | | | | | | | | | | | | | I thought I was going to end up using this for more stuff, but I've found better approaches. This commit also removes two more goto targets.
| * toke.c: factor out static yyl_keylookup()Aaron Crane2019-11-041-157/+143
