* Patch #1454481: Make thread stack size runtime tunable.Andrew MacIntyre2006-06-131-3/+74
| | | | | | | | | | Heavily revised, comprising revisions: 46640 - original trunk revision (backed out in r46655) 46647 - markup fix (backed out in r46655) 46692:46918 merged from branch aimacintyre-sf1454481 branch tested on buildbots (Windows buildbots had problems not related to these changes).

| | | | | | | | | | | | | | | | 46640 Patch #1454481: Make thread stack size runtime tunable. 46647 Markup fix The first is causing many buildbots to fail test runs, and there are multiple causes with seemingly no immediate prospects for repairing them. See python-dev discussion. Note that a branch can (and should) be created for resolving these problems, like svn copy svn+ssh://svn.python.org/python/trunk -r46640 svn+ssh://svn.python.org/python/branches/NEW_BRANCH followed by merging rev 46647 to the new branch.

| | | | | | | | | | | | | | | | | [ 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

* 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | 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.
