* avoid truncating time values when long is smaller than time_tTony Cook2012-01-181-2/+2
| | | | | | | | | long is only 32-bits on x64 Win32, but time_t is 64-bits. This was warning: POSIX.xs(1777) : warning C4244: 'initializing' : conversion from 'time_t' to 'const long', possible loss of data The check against (time_t)-1 is the approved check from ANSI C 89 and 99.
* Provide the correct POSIX return value for POSIX::dup2() on Win32.Nicholas Clark2011-12-301-0/+11
| | | | | | | | | | Microsoft, in their wisdom, chose to ignore the POSIX spec when implementing their dup2(), and have theirs return 0 on success, instead of the file descriptor. It seems that no other vendor is this, um, "special", so code the exception directly, as we don't run Configure on Win32, so there's little point probing for this. This resolves RT #98912.
* Convert POSIX::sleep to an XS wrapper for PerlProc_sleep().Nicholas Clark2011-12-301-0/+8
| | | | | | | | Previously it was a Perl wrapper for CORE::sleep, converting CORE::sleep's return value of elapsed time slept into the POSIX return value of seconds remaining. However, that approach could sometimes return a negative result if CORE::sleep had slept for more than a second longer than the requested time.
* Signal handlers must run before sigsuspend returnsLeon Timmermans2011-12-291-0/+4
| | | | | | | | | | The whole point of sigsuspend and pause is to wait until a signal has arrived, and then return *after* it has been triggered. Currently delayed/"safe" signals prevent that from happening, which might cause race conditions. This patch prevents that (as far as possible) by running the signal handlers ASAP.
* avoid double defining the POSIX::TCSANOW constant subTony Cook2011-11-281-2/+6
| | | | | | | | | On Win32 which has no native TCSANOW definition this would produce: Constant subroutine TCSANOW redefined at ../lib/POSIX.pm line -1. because the macro wasn't defined when building the unknown symbols table but was defined when building the defined symbols table.
* Change POSIX::Termios::setattr() to default to TCASNOW, not 0.Nicholas Clark2011-09-131-1/+8
| | | | | | | | 0 isn't valid on all operating systems. TCASNOW has the value 0 on most operating systems, but on Solaris (at least) TCASNOW, TCSADRAIN and TCSAFLUSH have the same values as the equivalent ioctls, TCSETS, TCSETSW and TCSETSF. Solaris faults 0, setting errno to EINVAL. This isn't useful as a default behaviour.
* Remove unneeded fallback definitions of dNOOP, dVAR etc from POSIX.xsNicholas Clark2011-09-131-20/+0
| | | | | | As POSIX.xs is not dual life, we can always rely on these macros being defined for us in perl.h. (And these days, dual life XS code should let Devel::PPPort take care of this sort of thing.)
* Merge the implementations of POSIX::{asctime,mktime} using ALIAS.Nicholas Clark2011-09-131-34/+18
| | | | | | This shares identical code marshaling 6 to 9 input arguments into a struct tm. However, as the return types differ we have to explicitly code pushing the return value onto perl's stack.
* Merge the implementations of POSIX::{access,mkfifo} using ALIAS.Nicholas Clark2011-09-131-7/+8
|
* Merge the implementations of POSIX::{close,dup,tcdrain} using ALIAS.Nicholas Clark2011-09-131-8/+8
| | | | On this platform, this reduces the shared object size by about .5K.
* Merge the implementations of 11 is*() functions in POSIX using XSANY.Nicholas Clark2011-09-131-154/+74
| | | | | | | is{alnum,alpha,cntrl,digit,graph,lower,print,punct,space,upper,xdigit} have identical structures, so replace them with one body to marshal arguments between Perl and C, calling the C library is*() function via a function pointer stored in the CV's XSANY.
* Merge the implementations of 10 maths functions in POSIX using ALIAS.Nicholas Clark2011-09-131-36/+44
| | | | | | 10 functions take a single NV argument and return an NV result. Merging them reduces the shared object size by over 2K on this platform. (Argument marshalling code in XS is not free.)
* Change POSIX::localeconv() to a table-driven implementation.Nicholas Clark2011-09-131-63/+58
| | | | | | This removes a lot of copy-paste code. [with a tweak by Ilmari that removed residual duplication]
* Merge the implementations of 2 sets of POSIX functions.Nicholas Clark2011-09-131-15/+14
| | | | | | Using ALIAS to merge POSIX::sig{pending,suspend} and POSIX::tc{flow,flush,sendbreak} reduces the size of POSIX.so by about 2K on this platform.
* Merge the implementations of 4 sets of POSIX::Termios methods.Nicholas Clark2011-09-131-87/+53
| | | | | | Using ALIAS to merge cfget[io]speed(), get[cloi]flag(), cfset[io]speed() and set[cloi]flag() reduces the size of POSIX.so by almost 2K on this platform.
* Merge the implementations of 2 pairs of POSIX::SigSet methods.Nicholas Clark2011-09-131-11/+14
| | | | | | Using ALIAS to merge addset() with delset() and emptyset() with fillset() reduces the shared object size, by removing duplicate marshaling code for arguments and return values. On this platform the saving is over .5K
* Store sigset_t used by POSIX::SigSet directly in the object SV.Nicholas Clark2011-09-131-22/+15
| | | | | | | | | | | | | | Previously POSIX::SigSet was using the PTROBJ typemap to store a pointer to a dynamically-allocated sigset_t as an IV (blessed into the class) This requires an explicit DESTROY to free the dynamic allocation, but fails badly if any POSIX::SigSet objects exist at ithread clone time, as the dynamic allocation is not duplicated in the new thread. (DESTROY is called in both threads, free-from-wrong pool or other jollity occurs.) Removing dynamic allocation removes the need for a DESTROY method. This change is analogous to the previous change in POSIX::Termios, and is made for the same reason.
* In POSIX.xs, extract allocate_struct() from POSIX::Termios::new().Nicholas Clark2011-09-131-7/+13
| | | | | The same code will be needed for POSIX::SigSet::new(), so share it as a small static function.
* Store struct termios used by POSIX::Termios directly in the object SV.Nicholas Clark2011-09-131-15/+13
| | | | | | | | | | | | | | | | | Previously POSIX::Termios was using the PTROBJ typemap to store a pointer to a dynamically-allocated struct termios as an IV (blessed into the class). This requires an explicit DESTROY to free the dynamic allocation, but fails badly if any POSIX::Termios objects exist at ithread clone time, as the dynamic allocation is not duplicated in the new thread. (DESTROY is called in both threads, free-from-wrong pool or other jollity occurs.) Removing dynamic allocation removes the need for a DESTROY method. This introduces a new OPAQUEPTROBJ typemap, but currently doesn't use the OUTPUT section, as that copies an existing structure, whereas POSIX::Termios->new() only needs to zero-allocate the right space. Assuming that this typemap should be of general applicability, it should be moved to the main typemap file.
* The Borland Chainsaw MassacreSteve Hay2011-09-101-3/+0
| | | | | Remove support for the Borland C++ compiler on Win32, as agreed here: http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2011-09/msg00034.html
* Redefine errno values for Visual Studio 2010Steve Hay2011-03-191-81/+112
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Perl traditionally stores WinSock error codes (values above 10000) in errno, with corresponding support for $! to stringify them properly. In Visual Studio 2010 (and presumably newer Windows SDKs) Microsoft has started to define additional errno constants in errno.h (values between 100 and 200) with conflicting names (e.g. EWOULDBLOCK). There are 2 ways to deal with this situation: 1) Redefine the errno.h constants back to the winsock values for the Errno and POSIX modules. 2) Translate the winsock error codes to the new errno constants in the socket implementation in win32/win32sck.c. Solution 1) has the advantage that any existing Perl code that has numeric error codes hard-coded in it will continue to work. Solution 2) has the advantage that XS code using external libaries can set errno to the new constants, and they will be handled consistently in the Perl core. It will however need additional support for other compilers and runtime libraries that don't support these new error codes. This commit implements solution 1).

* fix logic for a workaround in POSIX.xsStepan Kasal2009-11-231-2/+2
| | | | | | | | There is the assignment "RETVAL = 0" to silence the compiler in case it incorrectly reports return of an undefined value. This assignment should be present whenever *any* of the symbols is not defined. But the code was written so that the assignment was compiled only when *none* of the symbols was defined.

* Fix POSIX::tzset() as per Time::Piece::_tzset().Steve Hay2009-05-061-0/+112
| | | | | | | Jan Dubois suggested POSIX::tzset() should be fixed too, but there is no way to share the code since Time-Piece is dual-lived and POSIX is not. Therefore, the code is simply duplicated with appropriate comments to prompt keeping the two in sync.
* Remove all #ifdef MACOS_TRADITIONAL code in core and non-dual-life XS code.Nicholas Clark2009-04-271-16/+8
| | | | | | | | (MacOS support was removed from MakeMaker in 6.22, and merged to blead on 15th December 2004 with 5dca256ec738057dc331fb644a93eca44ad5fa14. After this point MacOS wouldn't even have been able to build the perl binary, because it would not have been able to build DynaLoader. If anyone wishes to resurrect MacOS, start by reversing this commit and the relevant part of that commit.)
* Adjustments to POSIX for the Haiku portIngo Weinhold2009-01-051-7/+17
| | | | | | | | | Message-Id: <20081029022544.413.1@knochen-vm.localdomain> I re-introduced the use of the WMUNGE() macro, which was (accidentally?) removed after 5.10.0. The macro is still a hack. As my added comment explains the use of the OS's W*() macros in this context is simply not correct and should probably better be fixed.
