Some tests hang at 100% CPU

[rljacobson]

Tests 0 and 4 and possibly later tests put my laptop in space-heater mode, using 100% CPU without making apparent progress. (I'm on macOS 12.5 Monterey.) Sampling the process with Activity Monitor shows that it is spending almost all its time in os_stat. This suggests to me that there is code somewhere that waits for the status of a file to change within a spin loop. Of course, on a POSIX system os_stat could be used on something other than a file, like a pipe or a socket for example. I'm not savvy enough to tell if this is the case just by looking at the data given by Activity Monitor.

Thanks for this. I have noticed some similar issues when I try to run the library on the Github Actions MacOS machines, but unfortunately, I do not have my own MacOS machine to debug them on, and the issues do not seem to appear on Ubuntu.

Could you do me a small favour and try the Version 2 WIP of the library (here: https://github.com/DanielLiamAnderson/Packaide/tree/v2) and tell me if you get the same error?

I will try to get access to a MacOS machine to test on at some point.

I will try to remember to take a look when I have a bit of free time. Would you like me to evaluate this branch for issue #2 as well?

[DanielLiamAnderson]

Sure, the Version 2 code has much better instructions and a correct requirements.txt that lists all of the dependencies so it should fix #2.

Oh, and the good news is that I can probably borrow a Mac in the near future, so I can hopefully start investigating this issue.
