* bpo-33929: multiprocessing: fix handle leak on race condition (GH-7921)Victor Stinner2018-06-271-3/+7
| | | | | | | | | 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-5001: More-informative multiprocessing error messages (#3079)Allen W. Smith, Ph.D2017-08-291-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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.

* Fix #9513 to remove relative imports from multiprocessing.Brian Curtin2010-08-041-1/+1
| | | | | | | The test suite currently skips test_multiprocessing on Windows because it fails on finding _multiprocessing in several win32-specific blocks. Removing the relative import lets this through and allows the test to run (and pass).
