* bpo-38840: Incorrect __all__ in multiprocessing.managers (GH-18034)Zackery Spytz2021-08-091-3/+4
| | | | | | | This was causing test___all__ to fail on platforms lacking a shared memory implementation. Co-Authored-By: Xavier de Gaye <xdegaye@gmail.com> Co-authored-by: Łukasz Langa <lukasz@langa.pl>
* Remove unnecessary pass statements (GH-27103)Elisha Hollander2021-07-131-1/+0

* bpo-43867: multiprocessing Server catchs SystemExit (GH-25441)Victor Stinner2021-04-161-6/+14
| | | | | The multiprocessing Server class now explicitly catchs SystemExit and closes the client connection in this case. It happens when the Server.serve_client() method reachs the end of file (EOF).
* Fix two typos in multiprocessing (GH-19571)Galden2020-04-181-2/+2

* bpo-39481: PEP 585 for a variety of modules (GH-19423)Batuhan Taşkaya2020-04-101-0/+3
| | | | | | | | | | - concurrent.futures - ctypes - http.cookies - multiprocessing - queue - tempfile - unittest.case - urllib.parse
* bpo-39850: Add support for abstract sockets in multiprocessing (GH-18866)Pablo Galindo2020-03-091-1/+5

* Remove binding of captured exceptions when not used to reduce the chances of ↵Pablo Galindo2019-11-191-2/+2
| | | | | | | creating cycles (GH-17246) Capturing exceptions into names can lead to reference cycles though the __traceback__ attribute of the exceptions in some obscure cases that have been reported previously and fixed individually. As these variables are not used anyway, we can remove the binding to reduce the chances of creating reference cycles. See for example GH-13135
* [3.9] bpo-37116: Use PEP 570 syntax for positional-only parameters. (GH-12620)Serhiy Storchaka2019-06-051-41/+3
| | | Turn deprecation warnings added in 3.8 into TypeError.
* bpo-37116: Use PEP 570 syntax for positional-only parameters. (GH-13700)Serhiy Storchaka2019-06-011-7/+4

* bpo-36867: Create the resource_tracker before launching SharedMemoryManagers ↵Pierre Glaser2019-05-131-0/+9
| | | | (GH-13276)
* bpo-36368: Ignore SIGINT in SharedMemoryManager servers. (GH-12483)Pierre Glaser2019-05-101-0/+4
| | | | Fix a bug crashing SharedMemoryManager instances in interactive sessions after a Ctrl-C (KeyboardInterrupt) was sent.
* bpo-36542: Allow to overwrite the signature for Python functions. (GH-12705)Serhiy Storchaka2019-05-061-0/+2
|
* bpo-36492: Deprecate passing some arguments as keyword arguments. (GH-12637)Serhiy Storchaka2019-04-011-4/+43
| | | | | | | | | | | | | | | | | | | | | | Deprecated passing the following arguments as keyword arguments: - "func" in functools.partialmethod(), weakref.finalize(), profile.Profile.runcall(), cProfile.Profile.runcall(), bdb.Bdb.runcall(), trace.Trace.runfunc() and curses.wrapper(). - "function" in unittest.addModuleCleanup() and unittest.TestCase.addCleanup(). - "fn" in the submit() method of concurrent.futures.ThreadPoolExecutor and concurrent.futures.ProcessPoolExecutor. - "callback" in contextlib.ExitStack.callback(), contextlib.AsyncExitStack.callback() and contextlib.AsyncExitStack.push_async_callback(). - "c" and "typeid" in the create() method of multiprocessing.managers.Server and multiprocessing.managers.SharedMemoryServer. - "obj" in weakref.finalize(). Also allowed to pass arbitrary keyword arguments (even "self" and "func") if the above arguments are passed as positional argument.
* bpo-35813: Tests and docs for shared_memory (#11816)Davin Potts2019-02-241-2/+149
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Added tests for shared_memory submodule. * Added tests for ShareableList. * Fix bug in allocationn size during creation of empty ShareableList illuminated by existing test run on Linux. * Initial set of docs for shared_memory module. * Added docs for ShareableList, added doctree entry for shared_memory submodule, name refactoring for greater clarity. * Added examples to SharedMemoryManager docs, for ease of documentation switched away from exclusively registered functions to some explicit methods on SharedMemoryManager. * Wording tweaks to docs. * Fix test failures on Windows. * Added tests around SharedMemoryManager. * Documentation tweaks. * Fix inappropriate test on Windows. * Further documentation tweaks. * Fix bare exception. * Removed __copyright__. * Fixed typo in doc, removed comment. * Updated SharedMemoryManager preliminary tests to reflect change of not supporting all registered functions on SyncManager. * Added Sphinx doctest run controls. * CloseHandle should be in a finally block in case MapViewOfFile fails. * Missed opportunity to use with statement. * Switch to self.addCleanup to spare long try/finally blocks and save one indentation, change to use decorator to skip test instead. * Simplify the posixshmem extension module. Provide shm_open() and shm_unlink() functions. Move other functionality into the shared_memory.py module. * Added to doc around size parameter of SharedMemory. * Changed PosixSharedMemory.size to use os.fstat. * Change SharedMemory.buf to a read-only property as well as NamedSharedMemory.size. * Marked as provisional per PEP411 in docstring. * Changed SharedMemoryTracker to be private. * Removed registered Proxy Objects from SharedMemoryManager. * Removed shareable_wrap(). * Removed shareable_wrap() and dangling references to it. * For consistency added __reduce__ to key classes. * Fix for potential race condition on Windows for O_CREX. * Remove unused imports. * Update access to kernel32 on Windows per feedback from eryksun. * Moved kernel32 calls to _winapi. * Removed ShareableList.copy as redundant. * Changes to _winapi use from eryksun feedback. * Adopt simpler SharedMemory API, collapsing PosixSharedMemory and WindowsNamedSharedMemory into one. * Fix missing docstring on class, add test for ignoring size when attaching. * Moved SharedMemoryManager to managers module, tweak to fragile test. * Tweak to exception in OpenFileMapping suggested by eryksun. * Mark a few dangling bits as private as suggested by Giampaolo.

* bpo-34054: multiprocessing uses time.monotonic() (GH-8118)Victor Stinner2018-07-061-3/+3
| | | | | The multiprocessing module now uses the monotonic clock time.monotonic() instead of the system clock time.time() to implement timeouts.
