| | | | | | | | Update docstring for `multiprocessing.Pool.map` to mention `pool.starmap()`. Prev PR: https://github.com/python/cpython/pull/17367 @aeros https://bugs.python.org/issue27873
* bpo-33725, multiprocessing doc: rephase warning against fork on macOS (GH-13841)Victor Stinner2019-06-051-2/+3
| | | Co-Authored-By: Barry Warsaw <barry@python.org>
* Fix documentation (GH-13721)Benjamin Yeh2019-06-051-0/+4
| | | Based on the source code https://github.com/python/cpython/blob/4a686504eb2bbf69adf78077458508a7ba131667/Lib/multiprocessing/pool.py#L755 AsyncResult.successful() raises a ValueError, not an AssertionError.
* bpo-33725: multiprocessing uses spawn by default on macOS (GH-13603)Victor Stinner2019-05-281-1/+6
| | | | On macOS, the multiprocessing module now uses the "spawn" start method by default.

* bpo-35491: Enhance multiprocessing.BaseProcess.__repr__() (GH-11138)Victor Stinner2018-12-141-3/+3
| | | | | | | | | | | | | | | | * Add the pid and parent pid to multiprocessing.BaseProcess.__repr__(). * Add negative sign (ex: "-SIGTERM") to exitcode (process killed by a signal) * Only call _popen.poll() once. Example: <ForkProcess(ForkPoolWorker-1, started daemon)> becomes: <ForkProcess name='ForkPoolWorker-1' pid=12449 parent=12448 started daemon> Example: <ForkProcess(ForkPoolWorker-1, stopped[SIGTERM] daemon)> becomes: <ForkProcess name='ForkPoolWorker-1' pid=12960 parent=12959 stopped exitcode=-SIGTERM daemon>
* bpo-22872: multiprocessing.Queue's put() and get() now raise ValueError if ↵Zackery Spytz2018-10-131-0/+8
| | | | | | | the queue is closed. (GH-9010) Previously, put() and get() would raise AssertionError and OSError, respectively.

|
* bpo-34605: Avoid master/slave terms (GH-9101)Victor Stinner2018-09-071-1/+1

* bpo-32362: Fix references to non-existent multiprocessing.Connection() (GH-6223)Bo Bayles2018-04-291-11/+17
|
* bpo-32051: Fix name shadowing in multiprocessing docs (GH-4469)Jason Yang2017-11-271-2/+2

* Replace KB unit with KiB (#4293)Victor Stinner2017-11-081-2/+2
| | | | | | | | | | | kB (*kilo* byte) unit means 1000 bytes, whereas KiB ("kibibyte") means 1024 bytes. KB was misused: replace kB or KB with KiB when appropriate. Same change for MB and GB which become MiB and GiB. Change the output of Tools/iobench/iobench.py. Round also the size of the documentation from 5.5 MB to 5 MiB.
* bpo-31965: fix doc for multiprocessing.connection.Client and Listener (#4304)Jelle Zijlstra2017-11-071-19/+11
| | | | | | | | | | | | | * fix doc for multiprocessing.connection.Client The authenticate argument does not exist on either Client or Listener: - https://github.com/python/cpython/blob/master/Lib/multiprocessing/connection.py#L483 (master) - https://github.com/python/cpython/blob/3.6/Lib/multiprocessing/connection.py#L478 (3.6) - https://github.com/python/cpython/blob/3.5/Lib/multiprocessing/connection.py#L478 (3.5) - https://github.com/python/cpython/blob/3.4/Lib/multiprocessing/connection.py#L487 (3.4) The documentation also claimed that these functions will call `current_process().auth_key`, for which I could find no evidence in the code. I rewrote the documentation to reflect the actual behavior. Also made some small changes to vary sentence structure.
* bpo-31304: Update starmap_async documentation. (GH-4168)Pablo Galindo2017-10-301-1/+1
| | | Update the kwarg in the documentation of `multiprocessing.pool.Pool.starmap_async`, from `error_back` to `error_callback` to match the source code..
