[PATCH] gitlab-ci: Use artifacts instead of dumping logs in the Cirrus-CI jobs
Posted by Thomas Huth 1 year, 2 months ago 
The meson log files can get very big, especially if running the tests in
verbose mode. So dumping those logs to the console was a bad idea, since
gitlab truncates the output if it is getting too big. Let's publish the
logs as artifacts instead. This has the disadvantage that you have to
look up the logs on cirrus-ci.com now instead, but that's still better
than not having the important part of the log at all since it got
truncated.

Fixes: 998f334722 ("gitlab: show testlog.txt contents ...")

 Note: I also tried to publish the junit xml files as artifacts
 instead, but while the cirrus-ci docs claim to support it, I only
 got unreadable XML output in my browser that way, so the .txt
 files look like the better option to me.

Having to go over to cirrus-ci.com is pretty awful user experiance,
especially as there's no direct link.

Does it have to be either/or, can't we do both ?

95% of the time the truncated testlog.txt is sufficient on its own.

It's not that bad, see e.g.:

  https://gitlab.com/thuth/qemu/-/jobs/3775523498

The log shows a link to cirrus-ci.com at the end:

  Build failed: https://cirrus-ci.com/build/4811273133621248

If you click on that URL, you've just got to go into the "build" and click 
through the build artifacts to get to the log that you want.

I'd say 95% of the time the normal console output (without the "cat 
.../testlog.txt") is already enough since meson prints the stdout and stderr 
of the failing tests to the console already.

FWIW, this is the test run with the truncated output that Peter complained 
about earlier today in IRC:

  https://gitlab.com/qemu-project/qemu/-/jobs/3768540680

Even if you click on the "complete raw" link there, you'll have a hard time 
finding the information that you are interested in. So I'd really prefer to 
not dump testlog.txt by default and only have it via the artifacts instead.

Could somebody write up some documentation for how to get from
"top level gitlab CI pipeline page" to "detailed logs for a
job failure", please? I'm finding that the UI for this (both
Cirrus and gitlab) is very non-obvious, so a writeup like
the above of "follow this link from the log, click this button,
go look at build artefact X" would be very helpful.
Somewhere in https://wiki.qemu.org/Merges is probably a
convenient place for thsi.

thanks

Ok, you convinced me.

How long is that log kept available?

No clue, I haven't seen anything related in the docs:

  https://cirrus-ci.org/guide/writing-tasks/#artifacts-instruction

... but I assume they will at least be available for a couple of days so 
you've got enough time to look at them in case a job failed.
