aehs29Im trying to get travis to build automatically through github integration, but I (obviously) hit the 50 minute time limit (free travis), does anyone know if theres a better solution?00:28
aehs29trying to avoid using some s3 workaround to get the sstate00:29
rburtonrun your own worker and persist the sstate00:29
rburtons3 can be too slow (and expensive) to persist sstate on00:29
rburtonyou can try using the sstate on yoctoproject.org but obviously you need to pin to the release and use poky etc00:30
rburtonbut the real solution is your own hardware, the runner on it, and a persistant sstate00:30

rburton(your own hw could obviously be on aws or whatever, you just need persistant local storage)00:31
rburtonoh and github actions are much nicer than travis :)00:32
rburtonah but actions don't do self-hosted yet so ignore me00:33

erbomischief: Go with spaces. Some parts like python functions must use four spaces, and then it's simpler to just do that in all of the recipe. OE-core uses tabs in shell functions, but if you're starting a new layer I see no point in mixing.04:09
mischiefokay. i ask because i think i have a bitbake syntax plugin for vim which i believe is 4 spaces, but my coworker seems to have used tabs in something he wrote :(04:11

iceawayI am on Yocto Sumo, and need to bring in some recipe changes (bug fixes) from newer versions. I don't suppose you can patch a recipe file from a .bbappend?07:43
erboiceaway: you can override a lot of stuff using a bbappend. But depending on how the original recipe looks, and what you need to change, it might be tricky to fix stuff in a bbappend.07:47
erboIf it gets too messy, you can always put the newer version of the recipe in your own layer.07:49
iceawayerbo: thanks, might just do that!07:49

filt3rthank you very much for the confirmation11:45

vixpHi all, I am experiencing a strange crash with a QT (5.9.7) application on my embedded platform built with yocto: "The Wayland connection experienced a fatal error (No child processes)". Can anyone shed some light on this, or point me in the right direction?17:38

kergothpepone: i wouldn't be at all surprised if minimal's .bb overrides that as a part of its goal. minimal. minimal is almost never the image you want17:43
kergothmight want to just create yourself a recipe at this point17:43
kergothimage, that is17:43

marler899712we're running into problems with sstate cache and our mirror server.  Does anyone know, should ever tgz file have a corresponding tgz.siginfo file?19:44

*** pung__ <pung__!~BobPungar@177.41.192.157> has joined #yocto20:31
marler899712It looks like the answer might be yes20:33
marler899712I think what happened is our build server failed while uploading it's sstate cache20:34
marler899712so then there was a bunch of archive files with missing siginfo files which caused any builds using that server to fail20:34
*** pung_ <pung_!~BobPungar@187.113.135.208> has quit IRC20:34
marler899712I'm wondering if there is an upload mechanism that wouldn't leave the server in a bad state on failure to upload20:34
marler899712if I upload the siginfo first and then the archive, does anyone know if that would work?20:35
JPEWmarler899712: You need both, and we ran into the same problem. We fixed it by running a script that cleans out sstate removing files missing their match20:37
marler899712So if you just have siginfo...will the build still fail?20:39
marler899712I know if you just have the archive it will20:39
*** tgamblin <tgamblin!~tgamblin@CPE64777de11593-CM64777de11590.cpe.net.cable.rogers.com> has quit IRC20:44
JPEWmarler899712: I don't remember off the top of my head, sorry... having the siginfo w/o the archive doesn't seem very useful anyway :)20:48
marler899712yeah, I just want to know if there is a way to upload files without creating a race condition where the server temporarily has invalid files that will cause a build to fail20:49
marler899712a better solution might to to patch oe-core to handle this case with a warning instead of an error20:49
JPEWmarler899712: IIRC, it only looks for siginfo if the archive is found, but don't quote me on that20:50
marler899712ok, well it's worth testing out20:50
smurraymarler899712: if you have the space, rsync new version to a different directory, then mv it into place after a successful upload?20:52
JPEWsmurray: I don't know if Crofton told you, but I borrowed part of your container presentation for a talk I gave at the platform security summit. It was very helpful :)20:55
marler899712smurray: that is a pretty good idea20:55
smurrayJPEW: heh, no, he didn't, but cool.  I need to get back to runc tinkering one of these days, but I'm entering AGL crunch time for CES now20:56
* smurray tries to forget he has an AGL blog post to write20:57
JPEWThe problem we have with rsync + sstate is multiple builds trying to upload at the same time... the sets of sstate intersect, so we need them all, but it causes issues where they overlap20:58
JPEWI'm not sure if the mv would help in that case :(20:58
marler899712yeah I was thinking about solutions like copying the old contents into the new before doing a mv, but that doesn't handle multiple uploaders20:59
marler899712you would need some sort of queue in that case20:59
JPEWmarler899712: It's a harder problem than it first seems :)21:00
marler899712yeah, if we fixed yocto to handle missing files then it wouldn't matter as much21:00
smurrayperhaps need something like a WebDAV backend to plug into21:00
smurrayor maybe the hash equiv server solves this, JPEW?21:00
JPEWno, hash equivalence doesn't protect you from missing siginfo21:01
smurrayJPEW: the hash equivalence server is read only, ie multiple builds couldn't run against it and populate it at the same time?21:03
JPEWsmurray: err, not sure what you mean :) multiple builds can report equivalent hashes. The HE server doesn't look at the sstate files at all, it just tracks hashes21:06
kergothhash equiv just lets you use sstate with a different checksum than this task has, if we know it'll produce the same results.21:06
smurrayright, okay, I'll shut up21:07
smurray;)21:07
JPEWAnyway, there are probably a few ways of solving this. Someone should bring it up at the 3.1 planning meeting21:08
JPEWBut, I have to take $CHILD to swim lessons now. TTYL21:09
marler899712raise $CHILD21:09
