New submission from STINNER Victor:
A colleague reported me that the Python test suite hangs on running
test_subprocess_send_signal() of test_asyncio. After analysing the issue, it
seems like the test hangs becaues the RPM package builder ignores SIGHUP using
something like:
def daemonize():
[...]
signal.signal(signal.SIGHUP, signal.SIG_IGN)
[...]
While we should see if Koji (software used to build packages) can be patched to
restore the default signal handler for SIGHUP, I would like to enhance
test_asyncio to not depend on the current SIGHUP signal handler.
I modified Lib/site.py to add "import signal; signal.signal(signal.SIGHUP,
signal.SIG_IGN)": on 406 test files, only test_asyncio hangs.
Attached PR fixes test_asyncio.
