Motivation¶

While tracking down the root cause for #131447 we encountered a lot of error messages like:

Jun 27 09:10:06 openqa openqa-gru[22285]: mktemp: failed to create file via template ‘/tmp/tmp.XXXXXXXXXX’: No space left on device
Jun 27 09:10:37 openqa openqa-gru[22774]: mktemp: failed to create file via template ‘/tmp/tmp.XXXXXXXXXX’: No space left on device
Jun 27 09:11:27 openqa openqa-gru[23797]: mktemp: failed to create file via template ‘/tmp/tmp.XXXXXXXXXX’: No space left on device
Jun 27 09:13:38 openqa openqa-gru[26670]: mktemp: failed to create file via template ‘/tmp/tmp.XXXXXXXXXX’: No space left on device
Jun 27 09:13:38 openqa openqa-gru[26684]: mktemp: failed to create file via template ‘/tmp/tmp.XXXXXXXXXX’: No space left on device

These are very hard to trace back to the code that triggered them. If we simply used more unique templates like
/tmp/tmp.webui.obs.rsync.XXXXXXXXXX and the like it would be much easier.

Acceptance criteria¶

• AC1: All temporary files/directories created by openQA including use unique templates

Suggestions¶

• The underlying Perl modules usually have options for setting templates (https://metacpan.org/pod/Mojo::File#tempdir)
• Review all occurences of using temp files and directories in os-autoinst and openQA and decide where we need to add a unique name template
• Also review https://github.com/os-autoinst/scripts/
• Optional: Fix where stuff is not properly cleaned up
