[New-bugs-announce] [issue31885] Cygwin: socket test suites hang indefinitely due to bug in Cygwin

[Erik Bray]

New submission from Erik Bray <erik.m.bray at gmail.com>:

Like issue31882, this is to mention an upstream bug in Cygwin that causes one of the tests in the test_socket test suite to hang indefinitely.  That bug is fixed upstream [1], but for now it would still be better to skip the test on Cygwin.

The bug is that in some cases a blocking send() (particularly for a large amount data) cannot be interrupted by a signal even if SA_RESTART is not set.

Fixes to this issue, along with issue31882, issue31883, and issue31878 provide the bare minimum for Cygwin to at least compile (not necessarily all optional extension modules) and run the test suite from start to finish (though there may be other tests that cause the interpreter to lock up, but that are currently masked by other bugs).
