Victor Stinner 647d1e1acd (Merge 3.3) test_faulthandler: skip test_read_null() on AIX
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.

Victor Stinner e08d4881f8 (Merge 3.3) test_faulthandler: use _sigsegv() instead of _read_null()
faulthandler._read_null() is not reliable: it does not crash on AIX.

Victor Stinner d5698cbbca Fix initialization of the faulthandler module
faulthandler requires the importlib if "-X faulthandler" option is present on
the command line, so initialize faulthandler after importlib.

Add also an unit test.

Victor Stinner 301f3f093c test_faulthandler: use a longer sleep (2.5 sec instead of 1.3 sec) in
_check_dump_tracebacks_later() to avoid failures if the system is slow.

Victor Stinner 7bba62fd68 faulthandler: dump all threads by default
* 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.

Victor Stinner c790a5346d faulthandler: dump_tracebacks_later() displays also the timeout 2011-04-08 13:39:59 +02:00
Victor Stinner de10f4054b faulthandler: one more time, fix usage of locks in the watchdog thread
* 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.

Victor Stinner 9bdb43e43f Issue #11765: don't test time.sleep() in test_faulthandler
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.
