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).

Guido van Rossum 137c49ce6a Patch #1643738 by Ulisses Furquim -- make the is_tripped variable

Guido van Rossum 8ee3e5aa93 - Changes donated by Elemental Security to make it work on AIX 5.3
with IBM's 64-bit compiler (SF patch #1284289).  This also closes SF
  bug #105470: test_pwd fails on 64bit system (Opteron).

Guido van Rossum 6297a7a9fb - PyEval_GetFrame() is now declared to return a PyFrameObject *

[ 559250 ] more POSIX signal stuff

Adds support (and docs and tests and autoconfery) for posix signal

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.

Guido van Rossum 8586991099 REMOVED all CWI, CNRI and BeOpen copyright markings.

Andrew M. Kuchling a1abb728bc Use METH_OLDARGS instead of numeric constant 0 in method def. tables 2000-08-03 02:34:44 +00:00
Thomas Wouters 334fb8985b Use 'void' directly instead of the ANY #define, now that all code is ANSI C.
Leave the actual #define in for API compatibility.
2000-07-25 12:56:38 +00:00
Tim Peters 4f1b2081e9 Removed all instances of RETSIGTYPE from the source code: signal
handlers "return void", according to ANSI C.
Removed the new Py_RETURN_FROM_SIGNAL_HANDLER macro.
Left RETSIGTYPE in the config stuff, because it's not clear to
me that others aren't relying on it (e.g., extension modules).
2000-07-23 21:18:09 +00:00
Tim Peters e21107145a Missed a return from a signal handler -- thanks to /F for pointing
it out!
2000-07-23 18:33:52 +00:00
Tim Peters 1be46844d9 Recent ANSIfication introduced a couple instances of
#if RETSIGTYPE != void
That isn't C, and MSVC properly refuses to compile it.
Introduced new Py_RETURN_FROM_SIGNAL_HANDLER macro in pyport.h
to expand to the correct thing based on RETSIGTYPE.  However,
only void is ANSI!  Do we still have platforms that return int?
The Unix config mess appears to #define RETSIGTYPE by magic
without being asked to, so I assume it's "a problem" across
Unices still.
2000-07-23 18:10:18 +00:00
Thomas Wouters 0796b00279 Further ANSIfication of functionpointers and declarations. Also, make sure
to return something if RETSIGTYPE isn't void, in functions that are defined
to return RETSIGTYPE. Work around an argumentlist mismatch ('void' vs.
'void *') by using a static wrapper function.
2000-07-22 23:49:30 +00:00
Thomas Wouters f3f33dcf03 Bunch of minor ANSIfications: 'void initfunc()' -> 'void initfunc(void)',
and a couple of functions that were missed in the previous batches. Not
terribly tested, but very carefully scrutinized, three times.

All these were found by the little findkrc.py that I posted to python-dev,
which means there might be more lurking. Cases such as this:

long
func(a, b)
	long a;
	long b; /* flagword */
{

and other cases where the last ; in the argument list isn't followed by a
newline and an opening curly bracket. Regexps to catch all are welcome, of
course ;)

Marc-André Lemburg 8bcfb8a5e0 Fixed symbol search for defining NSIG. It now also checks _NSIG
which some C libs define (e.g. glibc).

Added a fallback default value for NSIG which hopefully provides
enough room for signal slots.

Guido van Rossum 276fa43faf Fix another error on AIX by using a proper cast. 2000-06-30 23:04:18 +00:00
Guido van Rossum cc6a438d7f Trent Mick:
Fix warnings on 64-bit build build of signalmodule.c

- Though I know that SIG_DFL and SIG_IGN are just small constants,
there are cast to function pointers so the appropriate Python call is
PyLong_FromVoidPtr so that the pointer value cannot overflow on Win64
where sizeof(long) < sizeof(void*).
2000-06-28 22:26:21 +00:00
Guido van Rossum 65d5b5763c Thanks to Chris Herborth, the thread primitives now have proper Py*
names in the source code (they already had those for the linker,
through some smart macros; but the source still had the old, un-Py names).
