It managed to hang up right as I was leaving on a long weekend trip, and I didn't notice until I got back. I wanted to get a fresh runner going anyway, for the latest Windows Updates, but was waiting until I got back to try to avoid any issues while I was gone 😁. New runner is going now

@jeremyd2019 Would you like to check if this CI job is stuck again https://github.com/msys2-arm/msys2-autobuild/actions/runs/6570301888 ?

I've been ruminating on the idea of some sort of 'watchdog' to detect and kill stuck pacman processes automatically, but I haven't settled on the best language/technology to do so. It seems like python would be most convenient since autobuild is already python, I could put a background thread like I did to try polling the token, but I'm not familiar with process querying/killing modules.

What I've got so far is a cygwin commands to get the cygwin pid of the process I want to kill (what I really want is the child pacman process, this gets the newest pacman process older than 1800 seconds)

pgrep -xn -O 1800 pacman

coupled with the script I already had (because when stuck in this state cygwin kill is not sufficient)

It would be a bit clear if the reason of such CI failure is explained.

lost power, so any lack of runner in the near future will be due to that

power is back

unstuck it. the powershell variant in git-for-windows/git-for-windows-automation#61 (comment) was intriguing, it seems like it could be close to being turned into a 'watchdog', would just need to also query CreationDate field to see any pacman processes that have been running a long time (like a half hour? or hour?), and then arrange for it to run continuously (scheduled task?). Of course, I'd much rather get whatever bug is causing this fixed...

There's a stuck job now, but it doesn't seem to be the runner this time. Probably something on Github's end.

This seems to be a different issue. I think maybe the machine rebooted. I did a quick check and didn't notice any excess packages installed.

What?!? I deleted some of the cruft under %USERPROFILE% (go, .cargo mainly) and increased some free space. Will try to build rust again

Is #76 related?

Otherwise, try good old WinDirStat :)

https://github.com/msys2-arm/msys2-autobuild/actions/runs/11418583395/job/31772208187

seems to have gotten unstuck and errored out after some hours. (or anyone poked at it?)

Unrelated note: Runner groups are now available for everyone it seems. Not that it makes much difference with the current setup with a separate org, but good to know: https://github.blog/changelog/2024-10-17-actions-runner-groups-now-available-for-organizations-on-free-plan/

I killed the child pacman process, as usual.

Yeah, I could do away with the extra labels to differentiate between autobuild and CI instances and enforce it with runner groups instead, presumably.

It looks like it stuck again at checking package integrity...:

I killed dirmngr and keyboxd processes, and deleted ~/.gnupg, hopefully will make it happier. I'm clearing all the failed builds and am starting a build.

I also ran pacman -Scc since there has been a lot of package thrashing lately, maybe the disk was getting full?

Hmm, wasn't there a gnupg update recently? Maybe the dirmngr/keyboxd processes were still from the old version (since the same install is reused for each run), and that was causing issues?

Looks like it happened again. Killed pacman and dirmngr/keyboxd again.

During setup-msys2... that's different...
