* bpo-5001: More-informative multiprocessing error messages (#3079)Allen W. Smith, Ph.D2017-08-291-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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.

* Issue #25654:Victor Stinner2016-03-251-0/+23
| | | | | | | | | * multiprocessing: open file with closefd=False to avoid ResourceWarning * _test_multiprocessing: open file with O_EXCL to detect bugs in tests (if a previous test forgot to remove TESTFN) * test_sys_exit(): remove TESTFN after each loop iteration Initial patch written by Serhiy Storchaka.

* | Issue #14753: Make multiprocessing treat negative timeouts as it did in 3.2Richard Oudkerk2012-05-101-15/+0
| | | | | | | | | | | | | | | | In Python 3.2 and earlier, Process.join() and Connection.poll() treated negative timeouts as zero timeouts. Earlier versions from the 3.3 line of development treat them as infinite timeouts. The patch reverts to the old behaviour.
