Permission denied at /tmp/caxa - Multi user problem in linux

Hi, I just got this error when my CI tried to execute my binary: 2022/04/13 09:12:57 caxa stub: Failed to create the lock directory: mkdir /tmp/caxa/locks/myprogram/7qsvoyerli: permission denied

When I was trying my binary without CI, I used myuser, so caxa created a /tmp/caxa folder with drwxr-xr-x 4 myuser myuser permissions.

But when the CI user wanted to create the lock directory, it failed because the permissions of the caixa directory are not open enough for ciuser.

As a workaround I just chmod 777 -R /tmp/caxa/, but not sure if that could work for all caxa users, maybe some users want to scope the programs per user? Or a shared (with 777) for multi user programs?

@SrZorro Thank you very much for your work. I’ll get to this soon…

Excellent work! 😁

I think automating the tests for all aspects of multi-user scenarios may be too cumbersome. The tests may become too brittle (for example, I’d like to avoid involving Docker into the situation), and I think that the benefit may not be that great. So how about we perform some manual testing and call it a day? 🤷

There’s even a precedent.
