| | | | | | | | | | | | | | | | | [ 960406 ] unblock signals in threads although the changes do not correspond exactly to any patch attached to that report. Non-main threads no longer have all signals masked. A different interface to readline is used. The handling of signals inside calls to PyOS_Readline is now rather different. These changes are all a bit scary! Review and cross-platform testing much appreciated.

* Patch 775605: Cygwin pthread_sigmask() workaround patchJason Tishler2003-07-221-1/+1
| | | | | | | | | | | | | | | | | | Cygwin's pthread_sigmask() implementation appears to be buggy. This patch works around this problem by using sigprocmask() instead. This patch is implemented in a general way so it could be used by other platforms too. If this approach is deemed too risky, then I can work up a patch that just hacks Python/thread_pthread.h for Cygwin. Note that I tested this patch against 2.3c1 under Red Hat Linux 8.0 too. [snip] And finally, I need someone to regenerate pyconfig.h.in and configure with the same versions of the autotools that are normally used by Python. Neal kindly regenerated pyconfig.h.in and configure for me.

* Partial patch from SF #452266, by Jason Petrone.Guido van Rossum2001-10-161-2/+6
| | | | | | This changes Pythread_start_thread() to return the thread ID, or -1 for an error. (It's technically an incompatible API change, but I doubt anyone calls it.)
* Do not define _POSIX_THREADS if unistd.h defines it.Martin v. Löwis2001-10-151-1/+1
| | | | Check for pthread_sigmask before using it. Fixes remaining problem in #470781.
* Add SF patch #468347 -- mask signals for non-main pthreads, by Jason Lowe:Guido van Rossum2001-10-121-0/+26
| | | | | | | | | | | | | | | | | | | This patch updates Python/thread_pthread.h to mask all signals for any thread created. This will keep all signals masked for any thread that isn't the initial thread. For Solaris and Linux, the two platforms I was able to test it on, it solves bug #465673 (pthreads need signal protection) and probably will solve bug #219772 (Interactive InterPreter+ Thread -> core dump at exit). I'd be great if this could get some testing on other platforms, especially HP-UX pre 11.00 and post 11.00, as I had to make some guesses for the DCE thread case. AIX is also a concern as I saw some mention of using sigthreadmask() as a pthread_sigmask() equivalent, but this patch doesn't use sigthreadmask(). I don't have access to AIX.
* Improve threading on Solaris, according to SF patch #460269, submittedGuido van Rossum2001-09-101-3/+8
| | | | | | | | | | by bbrox@bbrox.org / lionel.ulmer@free.fr. This adds a configure check and if all goes well turns on the PTHREAD_SCOPE_SYSTEM thread attribute for new threads. This should remove the need to add tiny sleeps at the start of threads to allow other threads to be scheduled.
* GUSI on the Mac creates threads with a default stack size of 20KB, which isJack Jansen2001-08-291-1/+21
| | | | | not enough for Python. Increased the stacksize to a (somewhat arbitrary) 64KB.

* This patch partly (some stuff went in already) ports Python to Monterey.Trent Mick2000-08-231-0/+11
| | | | | | | | | | - Fix bug in thread_pthread.h::PyThread_get_thread_ident() where sizeof(pthread) < sizeof(long). - Add 'configure' for: - SIZEOF_PTHREAD is pthread_t can be included via <pthread.h> - setting Monterey system name - appropriate CC,LINKCC,LDSHARED,OPT, and CCSHARED for Monterey - Add section in README for Monterey build

| | | | | | | | | | | | | | | | | | | | | | | | | | The common technique for printing out a pointer has been to cast to a long and use the "%lx" printf modifier. This is incorrect on Win64 where casting to a long truncates the pointer. The "%p" formatter should be used instead. The problem as stated by Tim: > Unfortunately, the C committee refused to define what %p conversion "looks > like" -- they explicitly allowed it to be implementation-defined. Older > versions of Microsoft C even stuck a colon in the middle of the address (in > the days of segment+offset addressing)! The result is that the hex value of a pointer will maybe/maybe not have a 0x prepended to it. Notes on the patch: There are two main classes of changes: - in the various repr() functions that print out pointers - debugging printf's in the various thread_*.h files (these are why the patch is large) Closes SourceForge patch #100505.

* BSDI specific patches, inspired by Nigel Head and otto@mail.olympus.net.Guido van Rossum1998-10-071-1/+22
| | | | | | | | | | | Also (non-BSDI specific): - Change the CHECK_STATUS() macro so it tests for nonzero error codes instead of negative error codes only (this was needed for BSDI, but appears to be correct according to the PTHREADS spec). - use memset() to zero out the allocated lock structure. Again, this was needed for BSDI, but can't hurt elsewhere either.
