Gregory P. Smith c1ce93a4ab Fixes issue #9535: Fix pending signals that have been received but not yet
handled by Python to not persist after os.fork() in the child process.

Charles-François Natali e0e88b0483 Issue #13817: After fork(), reinit the ad-hoc TLS implementation earlier to fix
a random deadlock when fork() is called in a multithreaded process in debug
mode, and make PyOS_AfterFork() more robust.
2012-02-02 19:57:19 +01:00
Charles-François Natali 1f3ff7bc3f Issue #13156: revert changeset f6feed6ec3f9, which was only relevant for native
TLS implementations, and fails with the ad-hoc TLS implementation when a thread
doesn't have an auto thread state (e.g. a thread created outside of Python
calling into a subinterpreter).

Antoine Pitrou 4394e0db24 Issue #10517: After fork(), reinitialize the TLS used by the PyGILState_*
APIs, to avoid a crash with the pthread implementation in RHEL 5.  Patch

Victor Stinner 33feeab598 (Merge 3.1) Issue #11768: The signal handler of the signal module only calls
Py_AddPendingCall() for the first signal to fix a deadlock on reentrant or
parallel calls. PyErr_SetInterrupt() writes also into the wake up file.

  Clean up the fix to #9324 with some of the suggestions raised on python-dev
  in response to the original checkin.

  Move the validation from the original loop into a switch statement,
  and adjust a platform check in the tests.

Jean-Paul Calderone e54ddf1ed2 Skip signal handler re-installation if it is not necessary. Issue 8354. 2010-05-08 20:06:02 +00:00
Brian Curtin e5aa886b44 Implement #1220212. Add os.kill support for Windows.
os.kill takes one of two newly added signals, CTRL_C_EVENT and
CTRL_BREAK_EVENT, or any integer value. The events are a special case
which work with subprocess console applications which implement a
special console control handler. Any other value but those two will
cause os.kill to use TerminateProcess, outright killing the process.

This change adds win_console_handler.py, which is a script to implement
SetConsoleCtrlHandler and applicable handler function, using ctypes.

subprocess also gets another attribute which is a necessary flag to
creationflags in Popen in order to send the CTRL events.

Neal Norwitz 18aa388ca0 Fix:
* crashes on memory allocation failure found with failmalloc
 * memory leaks found with valgrind
 * compiler warnings in opt mode which would lead to invalid memory reads
 * problem using wrong name in decimal module reported by pychecker

Update the valgrind suppressions file with new leaks that are small/one-time
leaks we don't care about (ie, they are too hard to fix).

TBR=barry
TESTED=./python -E -tt ./Lib/test/regrtest.py -uall (both debug and opt modes)
  in opt mode:
  valgrind -q --leak-check=yes --suppressions=Misc/valgrind-python.supp \
    ./python -E -tt ./Lib/test/regrtest.py -uall,-bsddb,-compiler \
                        -x test_logging test_ssl test_multiprocessing
  valgrind -q --leak-check=yes --suppressions=Misc/valgrind-python.supp \
    ./python -E -tt ./Lib/test/regrtest.py test_multiprocessing
  for i in `seq 1 4000` ; do
    LD_PRELOAD=~/local/lib/libfailmalloc.so FAILMALLOC_INTERVAL=$i \
        ./python -c pass
  done

At least some of these fixes should probably be backported to 2.5.

Facundo Batista 7e251e83d5 Issue 1089358. Adds the siginterrupt() function, that is just a
wrapper around the system call with the same name.  Also added
test cases, doc changes and NEWS entry. Thanks Jason and Ralf
Schmitt.

Guido van Rossum 02de8979cc Patch #1583 by Adam Olsen.
This adds signal.set_wakeup_fd(fd) which sets a file descriptor to
which a zero byte will be written whenever a C exception handler runs.

I added a simple C API as well, PySignal_SetWakeupFd(fd).

Neal Norwitz ba3a16c6c3 Remove METH_OLDARGS:
Convert METH_OLDARGS -> METH_VARARGS: also PyArg_Parse -> PyArg_ParseTuple
  Convert METH_OLDARGS -> METH_NOARGS: remove args parameter
Please review.  All tests pass, but some modules don't have tests.
I spot checked various functions to try to make sure nothing broke.

Guido van Rossum 9e8181b809 Make better use of GNU Pth -- patch by Andy Dustman.
I can't test this, so I'm just checking it in with blind faith in Andy.
I've tested that it doesn't broeak a non-Pth build on Linux.

Changes include:

- There's a --with-pth configure option.

- Instead of _GNU_PTH, we test for HAVE_PTH.

- Better signal handling.

- (The config.h.in file is regenerated in a slightly different order.)

Guido van Rossum d2cd7adf6f Use typedef PyOS_sighandler_t and APIs PyOS_getsig() and
PyOS_setsig(), instead of directly calling signal() or sigaction().

This fixes the second half of bug #110611: the mysterious ignoring of
the first ^C when readline isn't used.
