Optimize pending calls in multithreaded applications. If a thread different
|
|
than the main thread schedules a pending call (:c:func:`Py_AddPendingCall`),
|
|
the bytecode evaluation loop is no longer interrupted at each bytecode
|
|
instruction to check for pending calls which cannot be executed. Only the
|
|
main thread can execute pending calls.
|
|
|
|
Previously, the bytecode evaluation loop was interrupted at each instruction
|
|
until the main thread executes pending calls.

:mod:`multiprocessing` now supports abstract socket addresses (if abstract
|
|
sockets are supported in the running platform). When creating arbitrary

|
addresses (like when default-constructing

:class:`multiprocessing.connection.Listener` objects) abstract sockets are
|
|
preferred to avoid the case when the temporary-file-generated address is too
|
|
large for an AF_UNIX socket address. Patch by Pablo Galindo.

Port python-gdb.py to FreeBSD. python-gdb.py now checks for "take_gil"
|
|
function name to check if a frame tries to acquire the GIL, instead of
|
|
checking for "pthread_cond_timedwait" which is specific to Linux and can be
|
|
a different condition than the GIL.

functions of :c:type:`PyModuleDef` are no longer called if the module state

the module is created and before the module is executed

(:c:data:`Py_mod_exec` function). More precisely, these functions are not

|
called if :c:member:`~PyModuleDef.m_size` is greater than 0 and the module

state (as returned by :c:func:`PyModule_GetState`) is ``NULL``.

Extension modules without module state (``m_size <= 0``) are not affected.
