Miss Islington (bot) 2070401411 [3.13] gh-140814: Fix freeze_support() setting start method as side effect (GH-144608) (#146009) ... gh-140814: Fix freeze_support() setting start method as side effect (GH-144608) freeze_support() called get_start_method() without allow_none=True, which locked in the default start method context. This caused a subsequent set_start_method() call to raise "context has already been set". Use allow_none=True and accept None as a matching value, since spawn.freeze_support() independently detects spawned child processes. Test that freeze_support() does not lock in the default start method, which would prevent a subsequent set_start_method() call. (cherry picked from commit ee5318025b) Co-authored-by: Gregory P.
