New submission from STINNER Victor <vstin...@python.org>:
test_asyncio hangs randomly on Python 3.7 on aarch64 RHEL7 LTO + PGO 3.7. The symptom is a failed build failing with: retry lost connection compile (retry) Full error: remoteFailed: [Failure instance: Traceback (failure with no frames): <class 'twisted.internet.error.ConnectionLost'>: Connection to the other side was lost in a non-clean fashion. Example of failed build: https://buildbot.python.org/all/#/builders/42/builds/4703 Configure command: ./configure --prefix '$(PWD)/target' --with-lto --enable-optimizations Compile command: make -j10 all End of the make output: -------- make run_profile_task make[1]: Entering directory `/home/buildbot/buildarea/3.7.cstratak-RHEL7-aarch64.lto-pgo/build' ./python -m test.regrtest --pgo || true 0:00:00 load avg: 1.07 Run tests sequentially 0:00:00 load avg: 1.07 [ 1/416] test_grammar (...) 0:01:40 load avg: 1.07 [ 24/416] test_asynchat 0:01:42 load avg: 1.07 [ 25/416] test_asyncio remoteFailed: [Failure instance: Traceback (failure with no frames): <class 'twisted.internet.error.ConnectionLost'>: Connection to the other side was lost in a non-clean fashion. ] -------- I ran manually "./configure --prefix '$(PWD)/target' --with-lto --enable-optimizations && make -j10 all" twice on the worker directly, but test_asyncio passed successfully (I tried it twice). ---------- components: Tests messages: 385712 nosy: vstinner priority: normal severity: normal status: open title: aarch64 RHEL7 LTO + PGO 3.7: "make" hangs when running test_asyncio versions: Python 3.7 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue43031> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
