signalmodule.c

Retry:

* signal.sigtimedwait()
* threading.Lock.acquire()
* threading.RLock.acquire()
* time.sleep()

Add _Py_fstat_noraise() function when a Python exception is not welcome.

All these functions only accept positive timeouts, so this change has no effect
in practice.

* Add _PyTime_AsTimespec()
* Add unit tests for _PyTime_AsTimespec()

when interrupted by a signal not in the *sigset* parameter, if the signal
handler does not raise an exception. signal.sigtimedwait() recomputes the
timeout with a monotonic clock when it is retried.

Remove test_signal.test_sigwaitinfo_interrupted() because sigwaitinfo() doesn't
raise InterruptedError anymore if it is interrupted by a signal not in its
sigset parameter.

fstat() may fail with EOVERFLOW on files larger than 2 GB because the file size type is an signed 32-bit integer.

Detect integer overflow on the file descriptor of the socket on 64-bit Python.

- interpreter startup and shutdown code moved to a new
  pylifecycle.c module
- Py_OptimizeFlag moved into the new module with the other
  global flags

descriptor is in blocking mode.

A side effect is that Python depends to the WinSock library.

ValueError on fstat() failure.

aways from zero, instead of rounding towards zero.

It should make test_asyncio more reliable, especially test_timeout_rounding() test.

Issue #16105: When a signal handler fails to write to the file descriptor registered with ``signal.set_wakeup_fd()``, report an exception instead of ignoring the error.

PyStructSequence_InitType() except that it has a return value (0 on success,
-1 on error).

 * PyStructSequence_InitType2() now raises MemoryError on memory allocation failure
 * Fix also some calls to PyDict_SetItemString(): handle error

- Issue #17782: Fix undefined behaviour on platforms where ``struct timespec``'s "tv_nsec" member is not a C long.

Add a private API to convert an int or float to a C timespec structure.

make _multiprocessing.win32.WaitForMultipleObjects interruptible when
the wait_flag parameter is false.  Patch by sbt.

TLS implementations, and fails with the ad-hoc TLS implementation when a thread
doesn't have an auto thread state (e.g. a thread created outside of Python
calling into a subinterpreter).
