* gh-113009: Fix multiprocessing Process.terminate() on Windows (#113128)Victor Stinner2023-12-151-24/+30
| | | | | | On Windows, Process.terminate() no longer sets the returncode attribute to always call WaitForSingleObject() in Process.wait(). Previously, sometimes the process was still running after TerminateProcess() even if GetExitCodeProcess() is not STILL_ACTIVE.
* gh-110036: multiprocessing Popen.terminate() catches PermissionError (#110037)Victor Stinner2023-09-291-2/+9
| | | | | | On Windows, multiprocessing Popen.terminate() now catchs PermissionError and get the process exit code. If the process is still running, raise again the PermissionError. Otherwise, the process terminated as expected: store its exit code.

* bpo-37369: Fix initialization of sys members when launched via an app ↵Steve Dower2019-06-291-2/+1
| | | | | | | container (GH-14428) sys._base_executable is now always defined on all platforms, and can be overridden through configuration. Also adds test.support.PythonSymlink to encapsulate platform-specific logic for symlinking sys.executable
* bpo-35872 and bpo-35873: Clears __PYVENV_LAUNCHER__ variable (GH-11745)Steve Dower2019-02-041-2/+20
| | | | After reading __PYVENV_LAUNCHER__ we now set sys._base_executable value for later use. Make the same changes for macOS to avoid extra platform checks.
* bpo-33929: multiprocessing: fix handle leak on race condition (GH-7921)Victor Stinner2018-06-271-2/+13
| | | | | | | | | Fix a race condition in Popen of multiprocessing.popen_spawn_win32. The child process now duplicates the read end of pipe instead of "stealing" it. Previously, the read end of pipe was "stolen" by the child process, but it leaked a handle if the child process had been terminated before it could steal the handle from the parent process.
* bpo-30794: added kill() method to multiprocessing.Process (#2528)Vitor Pereira2017-07-181-0/+2
| | | | | | | | | | | | | | * bpo-30794: added kill() method to multiprocessing.Process * Added entries to documentation and NEWS * Refactored test_terminate and test_kill * Fix SIGTERM and SIGKILL being used on Windows for the tests * Added "versionadded" marker to the documentation * Fix trailing whitespace in doc
* Fix bpo-30596: Add close() method to multiprocessing.Process (#2010)Antoine Pitrou2017-06-241-1/+4
| | | | | | | | | | * Fix bpo-30596: Add close() method to multiprocessing.Process * Raise ValueError if close() is called before the Process is finished running * Add docs * Add NEWS blurb
* Issue #28053: Applying refactorings, docs and other cleanup to follow.Davin Potts2016-09-091-5/+4

* Issue #18999: Make multiprocessing use context objects.Richard Oudkerk2013-10-161-8/+4
| | | | | This allows different parts of a program to use different methods for starting processes without interfering with each other.
* Stop making fork server have copy of semaphore_tracker_fd.Richard Oudkerk2013-08-221-2/+3

* Issue #8713: Support alternative start methods in multiprocessing on Unix.Richard Oudkerk2013-08-141-0/+102
