Partkeepr stuck

[kuon]

System Information

• PartKeepr Version: git a0236103806201a7eead7c33be5fe55ab852837b
• Reproducible on the demo system: No.
• OS FreeBSD 11.2

I have a weird issue with partkeepr being "stuck". The problem started manifesting itself today. I was under version 1.3.0 when the problem appeared. To be sure it was not fixed I tried with the latest git version.

The issue is simple. When running php app.php (through CLI or fpm) hangs forever. I am not familiar with php debuging, but I did a syscall trace:

$ truss php app.php

.... poll/select loop forever

It seems to be stuck after reading some timezone files.

I do not believe that this is a PartKeepr issue, it looks more like a system issue (kernel bug, or failing hard drive). Please re-open if you can pinpoint it to an actual PartKeepr bug.

I was able to pinpoint the issue to getPatreonStatus.

partkeepr.org is down and it is what is causing the issue. The curl process is stuck in curl_multi_select(). I waited a few minutes with no timeout.

I found this issue: https://bugs.php.net/bug.php?id=63842 but it seems old.

As for the partkeepr side of things I disabled the patreon status. I don't know if partkeepr should do something about this bug. Maybe don't use guzzle/guzzle which is abandoned and is the wrapper around curl.

[Drachenkaetzchen]

You're right, that should not happen, PartKeepr should continue to work even if partkeepr.org is down. Reopening to find a solution:

1. Don't retrieve the patreon status when logging in; instead, retrieve the patreon status async via a cronjob (similar to syncTips)
2. Replace guzzle with something else

[blackest]

Indexcontroller.php has a call for the patreon status. Rather strangely i found that safari was ok with it but chrome wouldn't load the page.

[Drachenkaetzchen]

Maybe it was an overlap, I fixed the non working partkeepr.org an hour ago

No feedback given for an extended period of time, closing the issue.

Feel free to re-open if you have additional information.
