* remove type annotations from multiprocessing. (#129381)Gregory P. Smith2025-01-30
| | | | | | | | | | | | | | | | * remove type annotations from multiprocessing. One of them was technically invalid per typing specs... but since we're not checking these in the stdlib today lets elide them. https://discuss.python.org/t/static-type-annotations-in-cpython/65068/13 * use the actual comment style annotation format Co-authored-by: 🇺🇦 Sviatoslav Sydorenko (Святослав Сидоренко) <wk.cvs.github@sydorenko.org.ua> --------- Co-authored-by: 🇺🇦 Sviatoslav Sydorenko (Святослав Сидоренко) <wk.cvs.github@sydorenko.org.ua>
* gh-125679: multiprocessing Lock and RLock - fix invalid representation ↵Duprat2024-11-07
| | | | string on MacOSX. (#125680)
* Cleanup multiprocessing comment and unusual import error message (#126532)Gregory P. Smith2024-11-07
| | | | Define constants as constants rather than calling `list(range(2))`. Explain which values must remain in sync via comments.
* gh-108520: Fix bad fork detection in nested multiprocessing use case (#108568)albanD2023-08-30
| | | | | | | | gh-107275 introduced a regression where a SemLock would fail being passed along nested child processes, as the `is_fork_ctx` attribute would be left missing after the first deserialization. --------- Co-authored-by: blurb-it[bot] <43283697+blurb-it[bot]@users.noreply.github.com> Co-authored-by: Antoine Pitrou <pitrou@free.fr>
* gh-77377: Ensure multiprocessing SemLock is valid for spawn-based Process ↵albanD2023-08-23
| | | | | | | | | | | | before serializing it (#107275) Ensure multiprocessing SemLock is valid for spawn Process before serializing it. Creating a multiprocessing SemLock with a fork context, and then trying to pass it to a spawn-created Process, would segfault if not detected early. --------- Co-authored-by: blurb-it[bot] <43283697+blurb-it[bot]@users.noreply.github.com> Co-authored-by: Antoine Pitrou <pitrou@free.fr>
* bpo-25066: Added repr for multiprocessing.Event (GH-29749)Kumar Aditya2021-12-09

* Fix typo in message from assert statement (GH-21283)Allen2020-08-17
| | | The error message was missing space between the action "acquire" and "_wait_semaphore" which is an attribute for instances of Condition.
* bpo-36867: Make semaphore_tracker track other system resources (GH-13222)Pierre Glaser2019-05-10
| | | The multiprocessing.resource_tracker replaces the multiprocessing.semaphore_tracker module. Other than semaphores, resource_tracker also tracks shared_memory segments. Patch by Pierre Glaser.
* bpo-34054: multiprocessing uses time.monotonic() (GH-8118)Victor Stinner2018-07-06
| | | | | The multiprocessing module now uses the monotonic clock time.monotonic() instead of the system clock time.time() to implement timeouts.
* bpo-5001: More-informative multiprocessing error messages (#3079)Allen W. Smith, Ph.D2017-08-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Make error message more informative Replace assertions in error-reporting code with more-informative version that doesn't cause confusion over where and what the error is. * Additional clarification + get travis to check * Change from SystemError to TypeError As suggested in PR comment by @pitrou, changing from SystemError; TypeError appears appropriate. * NEWS file installation; ACKS addition (will do my best to justify it by additional work) * Making current AssertionErrors in multiprocessing more informative * Blurb added re multiprocessing managers.py, queues.py cleanup * Further multiprocessing cleanup - went through pool.py * Fix two asserts in multiprocessing/util.py * Most asserts in multiprocessing more informative * Didn't save right version * Further work on multiprocessing error messages * Correct typo * Correct typo v2 * Blasted colon... serves me right for trying to work on two things at once * Simplify NEWS entry * Update 2017-08-18-17-16-38.bpo-5001.gwnthq.rst * Update 2017-08-18-17-16-38.bpo-5001.gwnthq.rst OK, never mind. * Corrected (thanks to pitrou) error messages for notify * Remove extraneous backslash in docstring.
