* | Issue #23836: Fix the faulthandler module to handle reentrant callsVictor Stinner2015-04-011-40/+45
| | | | | | | | | | | | | | | | | | | | to its signal handlers. Use also _Py_write_noraise() instead of write() to retry write() if it is interrupted by a signal (fail with EINTR). faulthandler.dump_traceback() also calls PyErr_CheckSignals() to call the Python signal handler if a signal was received.

| | | | | | | | | | | | | | Issue #23654: Turn off ICC's tail call optimization for the stack_overflow generator. ICC turns the recursive tail call into a loop. Patch written by Matt Frank.

| * Issue #23433: Fix faulthandler._stack_overflow()Victor Stinner2015-02-111-4/+5
| | | | | | | | | | Fix undefined behaviour: don't compare pointers. Use Py_uintptr_t type instead of void*. It fixes test_faulthandler on Fedora 22 which now uses GCC 5.

|\ \ | |/ | | | | | | | | | | _read_null(), because _read_null() cannot be used on AIX. On AIX, reading from NULL is allowed: the first page of memory is a mapped read-only on AIX. _read_null() and _sigabrt() don't accept parameters.

|/ | | | | | | | - Use _testcapi.raise_signal() in test_signal - close also os.pipe() file descriptors in some test_signal tests where they were not closed properly - Remove faulthandler._sigill() and faulthandler._sigbus(): reuse _testcapi.raise_signal() in test_faulthandler

| | | | | Use _set_abort_behavior() + abort() instead of raise(SIGABRT) which may write an error message and/or open a popup asking to report the fault.

* 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.
