adayi'm trying the gnome buildstream tutorial. at the "your first build" step ( https://wiki.gnome.org/Newcomers/BuildSystemComponent#Your_first_build ) i get this error - `Error loading project: Could not find file at /home/aday/checkout/buildstream/project.conf`12:23
adayany advice? i don't see project.conf mentioned in any of the docs12:23
jmacproject.conf should be in the gnome-build-meta directory, checked out in the previous step12:24
jmacIt looks like you're running it from the buildstream directory, not gnome-build-meta12:25
adayjmac: ah ok, thanks12:25
mcatanzaro(does the tutorial include a cd command? it would avoid that confusion.)12:31
mcatanzaro(can't check, trying to figure out why ephy is crashing on start...)12:32
jmacIt does, although I think I missed it when I first tried it too12:50

tristanaday, I've been in crazy meetings alot... I think you are running `bst` in the buildstream checkout, without specifying the `-C / --directory` option to the project you are trying to build13:57
tristanah, I think that's been explained by jmac and mcatanzaro :)13:58
tristanIn the tutorial I did mention that "all examples assume you are in the gnome-build-meta directory" (or similar)13:58
adaytristan: yep, i've over that hurdle now thanks13:59
tristanmcatanzaro, just checked to confirm, the `cd` is in the first example followed by the assumption; however it can be easy to skim over14:00
gitlab-br-botbuildstream: merge request (175-refactor-integration-tests->master: Resolve "Refactor integration tests") #233 changed state ("opened"): https://gitlab.com/BuildStream/buildstream/merge_requests/23314:24
adayany advice on why i'm hitting this build error? https://paste.gnome.org/ppew7sxjt14:28
adayi assumed that it's because i'm out of disk space, but i've got about 15GB free14:28
ssam2ostree works this out based on a %age of free space14:35
ssam2currently buildstream doesn't clean up its cache automatically at all14:36
ssam2it saves results of failed builds, which can take up quite a lot of space ... you can do `rm -Rf ~/.cache/buildstream/builds` to delete that (assuming you're using the default config)14:36

adaythanks ssam2. i'm still a bit confused though - i have 7.8% disk free, and it's warning about having less than 3%14:42
ssam2do you have multiple disks or partititions ?14:43
ssam2that exact message comes from OSTree14:43
adayssam2: yes, that % is for my ~/ partition14:43
ssam2right14:43
ssam2that is a bit weird then14:43
ssam2this is where that error comes from: https://github.com/ostreedev/ostree/blob/master/src/libostree/ostree-repo-commit.c#L135614:47
ssam2it seems to do `fstatvfs()` to find out how much is free... which doesn't really tell me anything about what might be going wrong14:48
adayi cleared the builds and retried, and i'm hitting the same issue14:57
ssam2did it free up much disk space?15:04
ssam2artifact cache expiry is something we have more or less been ignoring, which we can't continue to ignore much longer15:05
ssam2so i don't have a great answer here15:05
adayssam2: no, it's about the same15:07
adaybut like i said, i *should* have enough space15:07
ssam2yeah15:08
ssam2there's probably a way to work around this by disabling that ostree feature15:08
ssam2if you do `ostree --repo=~/.cache/buildstream/artifacts/ostree config set core.min-free-space-percent 0` it should "fix" things15:10
ssam2it would be nice to know why it's calculating the amount of free space incorrectly, but without being able to reproduce it locally i don't think i have much chance of figuring that out15:11
adayssam2: mhh, i did that but i'm still getting the error15:13
ssam2argh! i have no idea then15:15

mcatanzaroaday: Do you have a GitLab (upstream) account so you can file an issue?15:21
mcatanzaroIt lets you log in with GitHub etc., if that makes a difference15:22
adaymcatanzaro: yes, i'll do that15:24
