* style: Detabify indentation of the C code maintained by the core.Michael G. Schwern2021-01-171-200/+200
| | | | | | | | | | | This just detabifies to get rid of the mixed tab/space indentation. Applying consistent indentation and dealing with other tabs are another issue. Done with `expand -i`. * vutil.* left alone, it's part of version. * Left regen managed files alone for now.
* Fix cygwin buildKarl Williamson2020-12-081-8/+8
| | | | A macro name changed, and I didn't see it in the grep
* Remove use of dVAR in coreDagfinn Ilmari Mannsåker2020-07-201-4/+0
| | | | | It only does anything under PERL_GLOBAL_STRUCT, which is gone. Keep the dNOOP defintion for CPAN back-compat
* Fix cygwin Perl_utf16_to_utf8 parameter typesDagfinn Ilmari Mannsåker2020-06-181-2/+2
| | | | | | | Commit f46dcac2d383af532d3e8c014488fba83a514309 changed the I32 arguments of Perl_utf16_to_utf8() to Size_t and updated all callers that called it via the utf16_to_utf8 macro, but missed the fully-qualified call in cygwin.c.
* Convert issue links from rt.perl.org to GitHubDan Book2019-11-261-1/+1

* Change bug URL from http://rt.perl.org to https://rt.perl.orgMax Maischein2019-10-111-1/+1
| | | | | | | | | | | | | This updates the bug tracker URL from http://rt.perl.org to https://rt.perl.org. There is a place in the code, in corelist.pl, that is sensitive to the URL of the bug tracker. This now understands both versions of the bug tracker URL. Ideally, this will be consolidated once the dust settles. This patch also updates ExtUtils::CBuilder, Safe, threads and threads::shared to point to the new bug tracker URL.

* make exec keep its argument list more reliablyZefram2017-12-141-10/+18
| | | | | | | | | | Bits of exec code were putting the constructed commands into globals PL_Argv and PL_Cmd, which could then be clobbered by reentrancy. These are only global in order to manage their freeing, but that's better managed by using the scope stack. So replace them with automatic variables, with ENTER/SAVEFREEPV/LEAVE to free the memory. Also copy the strings acquired from SVs, to avoid magic clobbering the buffers of SVs already read. Fixes [perl #129888].
* Change some strncmp(), etc. to strBEGINs()Karl Williamson2017-11-061-2/+2
| | | | | The latter is much clearer as to what's going on, and the programmer and program reader don't have to count characters.
* Convert strcmp into strEQ, strNEKarl Williamson2017-10-241-4/+4
| | | | The latter two are easier to read
* PATCH: [perl #127708] segfault in "$!" in threadsKarl Williamson2016-04-091-4/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This was showing up on Darwin because its setlocale is particularly not thread safe. But the problem is more generic. Using locales just isn't a good idea in a threaded application, as locales are process-wide, not thread-specific. Calling setlocale() changes the locale of all threads at the same time. Further the return of setlocale() is a pointer to internal storage. If you call setlocale() just to learn what it currently is without actually changing the locale, there is no guarantee that another thread won't interrupt your thread, switching the locale to something else before you've had a chance to copy it somewhere else for safekeeping, and the internal storage may have been freed during that interruption, leading to things like segfaults. This is a problem that has been around in the locale handling code for a long time. I don't know why it hasn't shown up before, or maybe it has and is not reproducible because it's timing dependent, and so any problems didn't have tickets written for them, or were rejected as not reproducible. But the problem has been made worse in recent releases. Only fairly recently has perl changed so this problem can occur in programs that don't use locale explicitly: ones that don't 'use locale' nor call setlocale(). This ticket is for such a program that gets a locale-related segfault, without ever touching locales itself. I have done an audit of the perl source, looking for all such occurrences, and this patch fixes all of them that I found. The only other ones, besides "$!", is in converting to/from UTF-8 in cygwin.c. In all such cases, perl briefly switches the locale, does an operation, then switches back. The solution here is to add mutexes to make these areas of code uninterruptible critical sections, so that they can rely on having the locale be what they expect it to be during the entirety of the operation, and can't have a setlocale() from another thread free internal storage. But this is not a general solution. A thread executing these sections can interrupt some other thread doing a setlocale() and zap that. However, we have long cautioned against doing setlocales() in a thread, and that caution was strengthened in a commit made yesterday, fc82b82ef4784a38877f35f56ee16f14934460ce. The current commit should make safe all threaded programs that don't use locales explicitly. It's too close to the 5.24 release to do the rearchitecting required for a general solution. That would involve adding more critical sections. POSIX 2008 introduced new locale handling functions that are thread-safe, and affect only a single thread, and don't require mutexes. The ultimate solution would be to use those tools where available, and to hide from the outer code which set is being used. Thus, perl would be thread-safe on such platforms, while remaining problematic on older ones, though fixed so segfaults wouldn't occur. Tony Cook believes we could emulate the newer behavior on all platforms at a significant performance penalty. I think this would require a lot of code, and suspect there would be glitches in it for XS code. But he may have some ideas about how to do it simply. In any case, this has to wait until post 5.24. Three other notes: It seems to me that the cygwin code could be replaced by equivalent code that doesn't use locales at all. The comments in the source seem to even indicate that. I'll look into doing this in 5.25. Another possible reason that this hasn't shown up in earlier perls is that the problems may have been entirely affecting I/O operations and there are already mutexes involving I/O, and so those could be inadvertently protecting from, or at least minimizing, the problems found here. I haven't investigated to verify this. This commit doesn't add a test. I am asking on p5p for assistance in writing one
* avoid a "FILE" name conflict with cygwin's wchar.hTony Cook2014-02-181-0/+1
| | | | | | | | | | | | | | | | | | | | | The 1.7.28 release of cygwin (or possible a separate package released around the same time) header wchar.h includes the following code: typedef __FILE FILE; With PERLIO_NOT_STDIO set to true, the default for core source files, we #include nostdio.h which does: struct _FILE; #define FILE struct _FILE which turns the above code into: typedef __FILE struct _FILE; which isn't C. Disable this hack for cygwin.c
* Removed the ifdefs for INCOMPLETE_TAINTSBrian Fraser2013-09-211-2/+0
| | | | | This was added in 5.5/5.6 as a backwards-compatibility measure when taint was extended to happen in more places.
* Convert some uvuni() to uvchr()Karl Williamson2013-08-291-4/+4
| | | | | All the tables are now based on the native character set, so using uvuni() in almost all cases is wrong.
