* Issue #18948: improve SuppressCoreFiles to include Windows crash popup ↵Antoine Pitrou2013-10-081-20/+4
| | | | | | suppression, and use it in more tests. Patch by Valerie Lambert and Zachary Ware.
* Close #18957: The PYTHONFAULTHANDLER environment variable now only enables theVictor Stinner2013-09-081-7/+23

* (Merge 3.3) test_faulthandler: skip test_read_null() on AIXVictor Stinner2013-07-031-0/+2
|\ | | | | | | | | | | | | AIX maps the first page of memory at address zero as valid, read-only. Reading NULL is not a fault on AIX. This is utilized by IBM compiler optimizations. One speculatively can indirect through a pointer which may be null without first testing if null and defer the test before using the value.

* | Issue #17206: Fix test_cmd_line and test_faulthandler for my previous changeVictor Stinner2013-06-251-3/+5
| | | | | | | | | | (test.regrtest and test.script_helper enable faulthandler module in subprocesses).
* | (Merge 3.3) test_faulthandler: use _sigsegv() instead of _read_null()Victor Stinner2013-06-171-5/+5
|\ \ | |/ | | | | faulthandler._read_null() is not reliable: it does not crash on AIX.
| * test_faulthandler: use _sigsegv() instead of _read_null()Victor Stinner2013-06-171-5/+5
| | | | | | | | faulthandler._read_null() is not reliable: it does not crash on AIX.
* | Update various test modules to use unittest.main() for test discoveryBrett Cannon2013-06-131-4/+1
|/ | | | instead of manually listing tests for test.support.run_unittest().
* Fix indentation.Ezio Melotti2013-03-051-1/+1

* Closes #15969: rename new API to have consistent names in the faulthandler ↵Georg Brandl2012-09-221-19/+19

* Issue #15463: Write a test for faulthandler truncating the name of functionsVictor Stinner2012-08-011-0/+24
| | | | to 500 characters.
* Fix initialization of the faulthandler moduleVictor Stinner2012-07-311-0/+15
| | | | | | | faulthandler requires the importlib if "-X faulthandler" option is present on the command line, so initialize faulthandler after importlib. Add also an unit test.
* Closes #14729: Allowed test to pass on Windows by adjusting the test ↵Vinay Sajip2012-05-061-1/+1
| | | | condition slightly to allow for a Windows-specific error message.
* Issue #12868: Skip test_faulthandler.test_stack_overflow() on OpenBSD:Charles-François Natali2011-09-011-0/+3
| | | | sigaltstack(2) doesn't work when linked with pthread.
* Issue #12700: fix test_faulthandler for Mac OS X LionVictor Stinner2011-08-081-4/+5
| | | | Read from NULL raises SIGILL, not SIGSEGV, on Mac OS X Lion.
* Issue #12550: Add chain optional argument to faulthandler.register()Victor Stinner2011-07-131-3/+28
| | | | Call the previous signal handler if chain is True.
* Issue #12400: test_faulthandler now uses sys.__stderr__Victor Stinner2011-06-291-5/+1
| | | | instead of open(os.devnull, 'w')
* Issue #12400: fix test_faulthandler if regrtest captures sys.stderrVictor Stinner2011-06-291-8/+22
| | | | faulthandler.enable() requires that sys.stderr has a fileno() method.
* test_faulthandler: use a longer sleep (2.5 sec instead of 1.3 sec) inVictor Stinner2011-06-011-6/+7
| | | | _check_dump_tracebacks_later() to avoid failures if the system is slow.
* faulthandler: dump all threads by defaultVictor Stinner2011-05-071-6/+6
| | | | | | | | | | * Set the default value of all_threads arguments to True * Py_FatalError() dumps all threads, instead of only the current thread Dump only the current thread is not reliable. In some cases, Python is unable to retrieve the state of the current thread and so is unable to dump the traceback. faulthandler keeps a reference to the interpreter and so is always able to dump the traceback of all threads.
* faulthandler: dump_tracebacks_later() displays also the timeoutVictor Stinner2011-04-081-1/+3

* faulthandler: one more time, fix usage of locks in the watchdog threadVictor Stinner2011-04-081-18/+27
| | | | | | | | | | | * Write a new test to ensure that dump_tracebacks_later() still works if it was already called and then cancelled before * Don't use a variable to check the status of the thread, only rely on locks * The thread only releases cancel_event if it was able to acquire it (if the timer was interrupted) * The main thread always hold this lock. It is only released when faulthandler_thread() is interrupted until this thread exits, or at Python exit.
* faulthandler: fix compilating without threadsVictor Stinner2011-04-071-0/+7

* Issue #11765: don't test time.sleep() in test_faulthandlerVictor Stinner2011-04-041-10/+2
| | | | | | time.time() and/or time.sleep() are not accurate on Windows, don't test them in test_faulthandler. Anyway, the check was written for an old implementation of dump_tracebacks_later(), it is not more needed.
* test_faulthandler: improve the test on dump_tracebacks_later(cancel=True)Victor Stinner2011-04-031-18/+15

* test_faulthandler: fix regex on the check_dump_traceback_threads() tracebackVictor Stinner2011-04-031-3/+2

| | | | | | | * faulthandler_user() displays the tracebacks of all threads even if it is unable to get the state of the current thread * test_faulthandler: only release the GIL in test_gil_released() check * create check_signum() subfunction
