test fail: Failed to read process stat from /proc/21073/stat: [2] No such file or directory

[protist]

I'm installing backintime-git from the Arch Linux AUR PKGBUILD, and I get the following issue during the check phase. This is when I make the package, even before installing it (although I have the latest version already installed.) I'm fairly sure that it's not a packaging problem, because I can replicate the issue when running the command manually.

$ cd backintime/common
$ LANG=en_US.UTF-8 make test

The check completes properly, but my terminal continues to be spammed with the final lines. These are interspersed with normal output, and even continue after the check has completed. I also get constant pop-up notifications informing me that the backup has not completed because my snapshots folder cannot be found. (It's on a network drive that is not present.)

Thank you for the very quick fix! This prevents the WARNING: Failed to read process stat messages. However, I still get the "can't find snapshots folder" notifications. Is it possible to prevent this, or is it just a necessary part of the tests?

[Germar]

It "should" not appear. I"ll have a look, what went wrong. Though there are still some popup messages, that need to be muted. But can't find snapshots folder shouldn't be one of them...

[protist]

Thanks again. I'm happy to troubleshoot if helpful. Cheers.

I'm not sure if I was mistaken before, but I tried to makepkg again, and this time the warnings reappeared. However, they were only restricted to a few lines, and they had non-unique numbers, unlike before. I'm still getting the popup messages. I backup to an ssh-connected network drive.

Hmm. Must be a race condition... Sometimes I get those lines and sometimes all is fine

Too tired to do further debugging today. Will have a look soon

@emtiu Could you please add the distro-specific tag? THX!

Dear @protist ,

can you reproduce the problem with the current AUR backintime-git package?

Does anyone has an idea where in test_configfile.py this problem occures?

[protist]

Wow, this really is back in time! 🤣

Looks like the issue has changed in the last six years. It's not as annoying as before, but something weird is still happening.

python3 -m unittest  -b test/test_config.py

I don't get popups now either.

It seems to me that the original issues is fixed.

Your last posted output about "subprocess is still running" is related to #1292 .

Please feel free to re-open the issues and ask questions.
