Attempting to acquire the GIL after runtime finalization has begun in a
|
|
different thread now causes the thread to hang rather than terminate, which
|
|
avoids potential crashes or memory corruption caused by attempting to
|
|
terminate a thread that is running code not specifically designed to support
|
|
termination. In most cases this hanging is harmless since the process will
|
|
soon exit anyway.
|
|
|
|
While not officially marked deprecated until 3.14, ``PyThread_exit_thread``
|
|
is no longer called internally and remains solely for interface
|
|
compatibility. Its behavior is inconsistent across platforms, and it can
|
|
only be used safely in the unlikely case that every function in the entire
|
|
call stack has been designed to support the platform-dependent termination
|
|
mechanism. It is recommended that users of this function change their
|
|
design to not require thread termination. In the unlikely case that thread
|
|
termination is needed and can be done safely, users may migrate to calling
|
|
platform-specific APIs such as ``pthread_exit`` (POSIX) or ``_endthreadex``
|
|
(Windows) directly.

Python can correctly be configured and built with ``./configure
|
|
--enable-optimizations --disable-test-modules``. Previously, the profile
|
|
data generation step failed due to PGO tests where immortalization couldn't
|
|
be properly suppressed. Patch by Bénédikt Tran.
