This module contains functions to dump Python tracebacks explicitly, on a fault,
after a timeout, or on a user signal. Call :func:`faulthandler.enable` to
install fault handlers for the :const:`SIGSEGV`, :const:`SIGFPE`,
:const:`SIGABRT`, :const:`SIGBUS`, and :const:`SIGILL` signals. You can also
install fault handlers for the :const:`~signal.SIGSEGV`,
:const:`~signal.SIGFPE`, :const:`~signal.SIGABRT`, :const:`~signal.SIGBUS`, and
:const:`~signal.SIGILL` signals. You can also
enable them at startup by setting the :envvar:`PYTHONFAULTHANDLER` environment
variable or by using the :option:`-X` ``faulthandler`` command line option.

The fault handler is compatible with system fault handlers like Apport or the
Windows fault handler. The module uses an alternative stack for signal handlers
if the :c:func:`sigaltstack` function is available. This allows it to dump the
if the :c:func:`!sigaltstack` function is available. This allows it to dump the
traceback even on a stack overflow.

The fault handler is called on catastrophic cases and therefore can only use

Dump the tracebacks of all threads, after a timeout of *timeout* seconds, or
every *timeout* seconds if *repeat* is ``True``. If *exit* is ``True``, call

cleanup like flushing file buffers.) If the function is called twice, the new
call replaces previous parameters and resets the timeout. The timer has a
sub-second resolution.
