* bpo-37123: multiprocessing test_mymanager() accepts SIGTERM (GH-16349)Miss Islington (bot)2019-09-241-5/+6
| | | | | | | | | | | Multiprocessing test test_mymanager() now also expects -SIGTERM, not only exitcode 0. bpo-30356: BaseManager._finalize_manager() sends SIGTERM to the manager process if it takes longer than 1 second to stop, which happens on slow buildbots. (cherry picked from commit b0e1ae5f5430433766e023c1a6936aeba0f2b84e) Co-authored-by: Victor Stinner <vstinner@redhat.com>

| | | | | | | | | | | Fix test_forkserver_sigkill() of test_multiprocessing_forkserver: give more time to the first child process to complete, double the sleep in the parent process.

| | | | | | | | | | | | | | | When hunting memory leaks using -R 3:3, test_imap_unordered() of test_multiprocessing leaks randomly a few memory blocks. It is a false alarm: when testing using -R 3:20 for example, no leak is detected. Modify test_imap_unordered() to be closer to test_imap(): * Only test 10 numbers instead of 1000: it's a pool of 4 processes, so 10 is enough to test at least one number per process * Use chunksize=100 instead of chunksize=53 to mimick test_imap() (cherry picked from commit 23401fb960bb94e6ea62d2999527968d53d3fc65) Co-authored-by: Victor Stinner <vstinner@redhat.com>

* bpo-28134: Auto-detect socket values from file descriptor (#1349)Christian Heimes2018-01-291-1/+1
| | | | | | | | | | | | | | | Fix socket(fileno=fd) by auto-detecting the socket's family, type, and proto from the file descriptor. The auto-detection can be overruled by passing in family, type, and proto explicitly. Without the fix, all socket except for TCP/IP over IPv4 are basically broken: >>> s = socket.create_connection(('www.python.org', 443)) >>> s <socket.socket fd=3, family=AddressFamily.AF_INET6, type=SocketKind.SOCK_STREAM, proto=6, laddr=('2003:58:bc4a:3b00:56ee:75ff:fe47:ca7b', 59730, 0, 0), raddr=('2a04:4e42:1b::223', 443, 0, 0)> >>> socket.socket(fileno=s.fileno()) <socket.socket fd=3, family=AddressFamily.AF_INET, type=SocketKind.SOCK_STREAM, proto=0, laddr=('2003:58:bc4a:3b00::%2550471192', 59730, 0, 2550471192), raddr=('2a04:4e42:1b:0:700c:e70b:ff7f:0%2550471192', 443, 0, 2550471192)> Signed-off-by: Christian Heimes <christian@python.org>
