I took a look at the autopkgtest regression for php-luasandbox on arm64. https://autopkgtest.ubuntu.com/results/autopkgtest- focal/focal/arm64/p/php-luasandbox/20210908_213035_50d50@/log.gz
We fail on: FAIL profiler sorting [tests/profiler-sorting.phpt] I started a t4.medium arm64 instance on AWS, installed autopkgtest and ran: $ sudo autopkgtest php-luasandbox_3.0.3-2build2.dsc --apt- pocket=proposed -- null Each run, the test always passes: PASS profiler sorting [tests/profiler-sorting.phpt] Interesting. Full test output below: https://paste.ubuntu.com/p/3kZ2Yj4nKt/ The software I was running to conduct the tests, clearly showing php7.4 from -proposed is installed: $ uname -a Linux ip-172-31-28-33 5.11.0-1017-aws #18~20.04.1-Ubuntu SMP Fri Aug 27 11:19:40 UTC 2021 aarch64 aarch64 aarch64 GNU/Linux $ sudo apt-cache policy php7.4-cli php7.4-cli: Installed: 7.4.3-4ubuntu2.6 Candidate: 7.4.3-4ubuntu2.6 Version table: *** 7.4.3-4ubuntu2.6 500 500 http://ap-southeast-2c.clouds.ports.ubuntu.com/ubuntu-ports focal-proposed/main arm64 Packages 100 /var/lib/dpkg/status So why does the test consistently fail on autopkgtest infrastructure? Looking at the test itself: https://paste.ubuntu.com/p/kwZNrgb3fk/ We see why. The test itself is based on completing three busy loops counting from 0 to 1e6, 0 to 4e6 and 0 to 2e6, all within a 0.5s window. If the arm64 based autopkgtest server / VM is under high load, then it might get scheduled out and not complete within the timeframe, and cause the loop to break and the test to error. The test is inherently flaky and based on VM performance. On AWS with just this running, the autopkgtest passes every time. This should not be a reason to prevent php7.4 7.4.3-4ubuntu2.6 from being released to -updates. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1939853 Title: mysqli: Using a cursor with get_result() and prepared statements causes a segmentation fault To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/php7.4/+bug/1939853/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
