2024-01-12tests/avocado: partially revert unmasking of replay_linux testsAlex Bennée1-0/+3
It seems we were premature in declaring replay_linux.py fixed. The x86_64 image still seems to hang occasionally. I've raised a new bug to cover it: https://gitlab.com/qemu-project/qemu/-/issues/2094 Signed-off-by: Alex Bennée <alex.bennee@linaro.org>
2024-01-12readthodocs: fully specify a build environmentAlex Bennée2-7/+14
This is now expected by rtd so I've expanded using their example as 22.04 is one of our supported platforms. I tried to work out if there was an easy way to re-generate a requirements.txt from our pythondeps.toml but in the end went for the easier solution.

2024-01-12mtest2make: stop disabling meson test timeoutsDaniel P. Berrangé1-1/+2
The mtest2make.py script passes the arg '-t 0' to 'meson test' which disables all test timeouts. This is a major source of pain when running in GitLab CI and a test gets stuck. It will stall until GitLab kills the CI job. This leaves us with little easily consumable information about the stalled test. The TAP format doesn't show the test name until it is completed, and TAP output from multiple tests it interleaved. So we have to analyse the log to figure out what tests had un-finished TAP output present and thus infer which test case caused the hang. This is very time consuming and error prone. By allowing meson to kill stalled tests, we get a direct display of what test program got stuck, which lets us more directly focus in on what specific test case within the test program hung. The other issue with disabling meson test timeouts by default is that it makes it more likely that maintainers inadvertantly introduce slowdowns. For example the recent-ish change that accidentally made migrate-test take 15-20 minutes instead of around 1 minute. The main risk of this change is that the individual test timeouts might be too short to allow completion in high load scenarios. Thus, there is likely to be some short term pain where we have to bump the timeouts for certain tests to make them reliable enough. The preceeding few patches raised the timeouts for all failures that were immediately apparent in GitLab CI. Even with the possible short term instability, this should still be a net win for debuggability of failed CI pipelines over the long term. Signed-off-by: Daniel P.

2024-01-12qtest: bump migration-test timeout to 8 minutesDaniel P. Berrangé1-1/+1
The migration test should take between 1 min 30 and 2 mins on reasonably modern hardware. The test is not especially compute bound, rather its running time is dominated by the guest RAM size relative to the bandwidth cap, which forces each iteration to take at least 30 seconds. None the less under high load conditions with multiple QEMU processes spawned and competing with other parallel tests, the worst case running time might be somewhat extended. Bumping the timeout to 8 minutes gives us good headroom, while still catching stuck tests relatively quickly. Reviewed-by: Thomas Huth <thuth@redhat.com> Signed-off-by: Daniel P.

2024-01-11.gitlab-ci.d/buildtest.yml: Work around htags bug when environment is largePeter Maydell1-1/+4
Sometimes the CI "pages" job fails with a message like this from htags: $ htags -anT --tree-view=filetree -m qemu_init -t "Welcome to the QEMU sourcecode" htags: Negative exec line limit = -371 This is due to a bug in hflags where if the environment is too large it falls over: https://lists.gnu.org/archive/html/bug-global/2024-01/msg00000.html This happens to us because GitLab CI puts the commit message of the commit under test into the CI_COMMIT_MESSAGE and/or CI_COMMIT_TAG_MESSAGE environment variables, so the job will fail if the commit happens to have a verbose commit message. Work around the htags bug by unsetting these variables while running htags.
