tme5buildstream logging seems to have destroyed part of my output09:23
tme5cp: error writing './libcaffe2.so': No s[02:09:05] FAILURE pytorch/pytorch.bst: Running install-commands09:23
traveltissuesoops09:24
tme5don't suppose there is another place i could find a log?09:24
traveltissuesdid you --log-file?09:25
traveltissuesthe error there is just being truncated for terminal width aiui09:26
tme5no i didn't09:26

traveltissuesbenschubert, juergbi has forwarded the messages about the slowdown in show, the benchmarks did not show that which is worrying09:39
traveltissuesit's most probably coming from calculate_cache_key09:39
juergbiit might depend on artifact size (in number of files). the synthetic benchmark uses single file artifacts, iirc09:39
benschuberttraveltissues: agreed. I tested with https://gitlab.com/freedesktop-sdk/freedesktop-sdk/tree/bschubert/freedesktop-sdk-19.08.0-bst2, trying to build 'bootstrap/bash.bst' if you want to try to reproduce09:40
juergbiwe should really expand the benchmark to also measure performance with artifacts with a large number of files09:40
tme5traveltissues, as in the "No s" is the last thing to fit on the terminal?09:40
traveltissuesthe benchmark i used was the debian build used for the weekly emails09:40
tme5because the terminal is wide enough for more. it seems buildstream output hasn't waited for a LF, or has moved the cursor in a weird way09:41
tme5it's like that in the .cache/buildstream/logs file too09:41
juergbitraveltissues: yes, that's very useful to benchmark scalability with lots of elements, but we're currently lacking a test for elements with large directories in the build output09:42
*** lachlan has quit IRC09:42
traveltissuesbenschubert, i will raise an issue and look into it, thanks09:46
*** lachlan has joined #buildstream09:46
benschubertthanks a lot :)09:47
tpollardtme5: you can change some of the logging configuration via user conf09:49
tpollardtme5: https://buildstream.gitlab.io/buildstream/using_config.html?highlight=configuration#default-configuration09:50
tme5i'm not sure any of those options are useful09:52
tme5this seems like a bug not a misconfiguration09:52
tme5or i could be missing something09:53
coldtomit looks like a bug to me09:53

tme5follow up question (as it turns out the truncated message was "No space left on device" ...): what is .cache/buildstream/build ?10:00
tme5can i delete directories in there?10:00
benschuberttme5: which version of BuildStream do you have? (bst --version)10:01
tme51.4.110:01
benschuberthow much space do you have in ~/.cache/buildstream? (total available and free space)10:02
tme5010:02
benschubertand the total available?10:02
tme5i have about 5 MB left on my / device :)10:02
tme528 GB10:03
benschubertwhat are you trying to build? and what's the output of 'df -hs ~/.cache/buildstream/*' ?10:03
tme5sorry i'm not being clear, i mean that i have a 28 GB storage device, of which I have 5.5 MB left, because .cache/buildstream/build takes up 22 GB10:04
tme5i'm trying to build pytorch10:05
gitlab-br-bottpollard opened MR !1610 (tpollard/duplicated_messagelines->master: _context.py: Remove duplicated log_message_lines assign) on buildstream https://gitlab.com/BuildStream/buildstream/merge_requests/161010:05
tme5is it safe to delete the directories in build/ ? is that the location of the build sandboxes?10:06
benschubertmmh it would seem weird that pytorch needs more than 22GB of space to build. you can safely destroy ~/.cache/builsdstream/build, it's normally only temporary files for building10:06
benschubertyep10:06
tme5benschubert, i have a large dir there from a previous failed build too. i imagine there is space without that10:08
*** bochecha has quit IRC10:08
tme5will give it a shot. thanks for the help :)10:08
benschubertnormally this should be cleaned up after the run10:08

traveltissuesbenschubert, i'm not able to access that branch on freedesktop-sdk10:26
traveltissuesi might not have permission10:27
benschubertuh? it's public, the branhc name is 'bschubert/freedesktop-sdk-19.08.0-bst2' right?10:27
traveltissuesi think it's a bug in gitlab, i can check it out just not access via webui10:28
traveltissuesnvm10:28
benschubertwow ok x')10:29
traveltissueswas this moved? maybe it's a broken redirect10:29
benschubertNo, hasn't moved10:31
