Title:
python3.6 test_ssl fails reliably on systems under load
Status in Auto Package Testing:
Won't Fix
Status in python3.6 package in Ubuntu:
New
Bug description:
$ autopkgtest-buildvm-ubuntu-cloud --arch i386
put system under load; e.g. pull-lp-source boost1.67; cd boost1.67;
DEB_BUILD_OPTIONS=parallel=12 ./debian/rules build should do it, on an
4core/8hypercore system
$ autopkgtest -s --shell --apt-pocket=proposed --apt-upgrade python3.6
--test-name testsuite -- qemu -c 1 -q qemu-system-i386 ./autopkgtest-
cosmic-i386.img
test_ssl fails
To rerun test_ssl alone, one can do:
$ python3.6 -W default -bb -E -R -m test -j 1 -w -uall,-network,-urlfetch,-gui test_ssl --verbose
in a racy manner, for many test cases, due to ConnectionRefused from
the TestEchoServer
One way to solve this is to reduce the load, cause without load
TestEchoServer keeps up just fine.
Symptoms are s.connect failing with ConnectionRefusedError, or for
example s.getpeercreds failing with Transport not connected.
I'm not sure it's worth any time fixing this test-server
implementation, as clearly it is testing the ssl server/client bits,
that work correctly on a normal, not-under-stress systems. And thus
the ssl bits are correctly validated.
I will try to create a reproducer which does not involve VMs and
stressing host.
meanwhile it would be nice to run python tests on slightly bigger
machines, e.g. mark it as big_packages.
