ricotzhello :), I am wondering if this build is stuck or still working hard in the background? https://launchpad.net/ubuntu/+source/libreoffice/1:7.1.1~rc2-0ubuntu1/+build/2108393106:40
ricotzsame for https://launchpad.net/ubuntu/+source/libreoffice/1:7.1.1~rc2-0ubuntu1/+build/2108393206:41
=== icey_ is now known as icey
cjwatsonricotz: I can't say, don't know this package's build system well enough10:04
cjwatsonricotz: IIRC that sort of thing is normally a pkgbinarymangler bug of some kind10:05

ricotzcjwatson, I see, it seems it hasn't moved in the last hours, could you cancel and restart both?10:57
cjwatsonricotz: cancelled, do you want to grab build logs for inspection before I retry?10:59
ricotzcjwatson, grabbed them both, please proceed :)11:00
cjwatsonricotz: done11:15
ricotzcjwatson, thank you11:37

ricotzcjwatson, if you are still around, please cancel and restart https://launchpad.net/ubuntu/+source/libreoffice/1:7.1.1~rc2-0ubuntu1/+build/2108393322:51
cjwatsonricotz: can cancel; is there any reason to believe a retry will work?22:51
ricotzcjwatson, the previous retry for amd64 worked22:51
ricotzthe other arm64 is still running22:52
ricotzthis might be triggered by the recent load on the builders, and calmed down afaics22:53
cjwatsonricotz: hm, OK, retried.  I think it's more likely to be some kind of occasional race in pkgstripfiles (perhaps when run in parallel?), but not sure22:54
RikMillsthere are a few KDE packages that sometimes do that 'INFO: pkgstripfiles: waiting for lock' for quite a long time. they do eventually break that loop and finish22:55
cjwatsonI've also seen it apparently run forever22:56
cjwatsonit may be subtle in a way I don't currently understand22:56
RikMillsI'm glad I have not had that then22:56
cjwatson(forever as in I noticed builds that had been running for a week stuck there)22:56
RikMillsO_O22:56
ricotzcjwatson, the interesting part of the earlier amd64 log is https://paste.debian.net/plain/118713022:56
cjwatsonI realize this is not an astronomical or theological definition of forever but still :)22:56
RikMillslonger that humanly tolerable....22:57
RikMills*than22:57
cjwatsonricotz: ah yes, that looks rather like bad error handling then, one would think it should have given up there22:57
cjwatson(leaving aside whatever caused that error to start with, which isn't obvious to me)22:58
ricotzcjwatson, there are disk space issues in the past, which the packaging has a mitigation for, but not sure if this gets hit again due the mangler23:00
ricotzcjwatson, thank you for restarting23:01
ricotzcjwatson, jfyi the other logs contain the "same" error23:09
tsimonq2Completed builds 290915 successful 49178 failed.23:43
tsimonq2We certainly don't need all of this data.23:44
tsimonq2I'm not seeing a way I can just delete old builds - does the Launchpad tooling do this by itself?23:44
cjwatsonCan you be more specific?23:45
cjwatsonAnd why is it important?23:46
tsimonq2It isn't important, I would just like to be somewhat thoughtful when the Lubuntu CI pumps out many, many builds per day. It's extremely useful for us in Lubuntu development, but we really don't need old build logs and artifacts from more than a week ago at best.23:48
tsimonq2I'm referring to the PPAs under ~lubuntu-ci.23:48
cjwatsonArtifacts are automatically garbage-collected after a while when they're no longer published (in public PPAs, anyway).23:48
cjwatsonWe generally keep things like old build logs forever.  It's not particularly expensive for us to do so, and they're the sort of thing that's often unpredictably useful years later when doing some kind of archaeology.23:49
cjwatsonIf we didn't GC artifacts that would indeed become a problem for us much more quickly, but build logs are on average rather smaller.23:50
cjwatsonThere's no way to manually delete old builds.23:50
cjwatson(Short of SQL surgery on our part, which is much more expensive in terms of human time ...)23:50
tsimonq2That answers my query; if sysadmins are ever looking at things and it becomes a problem over a couple of years, feel free to purge those old logs. If it's not much of a nuisance then it looks like we're fine for now.23:50
tsimonq2I understand if it would take more work than it's worth. :)23:51
cjwatsonI can say with some confidence that build logs are unlikely to be anywhere near the first place we go looking for space :-)23:51
tsimonq2Sounds good, thanks cjwatson. :)23:51
cjwatsonOut of curiosity let me see if I can figure out how much space your build logs are currently using ...23:52
