* [3.10] gh-97514: Don't use Linux abstract sockets for multiprocessing ↵Miss Islington (bot)2022-10-201-5/+0
| | | | | | | | | | | | | | | | | | | | | | (GH-98501) (GH-98503) Linux abstract sockets are insecure as they lack any form of filesystem permissions so their use allows anyone on the system to inject code into the process. This removes the default preference for abstract sockets in multiprocessing introduced in Python 3.9+ via https://github.com/python/cpython/pull/18866 while fixing https://github.com/python/cpython/issues/84031. Explicit use of an abstract socket by a user now generates a RuntimeWarning. If we choose to keep this warning, it should be backported to the 3.7 and 3.8 branches. (cherry picked from commit 49f61068f49747164988ffc5a442d2a63874fc17) Co-authored-by: Gregory P. Smith <greg@krypto.org> Automerge-Triggered-By: GH:gpshead

* bpo-34054: multiprocessing uses time.monotonic() (GH-8118)Victor Stinner2018-07-061-4/+4
| | | | | 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.D2017-08-291-2/+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.
