@hexa:lossy.networkhexa (signing key rotation when) Mic92: 16:39:48
@hexa:lossy.networkhexa (signing key rotation when)soi recent macos, but outdated nix16:39:58
@hexa:lossy.networkhexa (signing key rotation when)oh, but not all of them 😄 16:40:44
@joerg:thalheim.ioMic92 hexa (signing key rotation when): I vaguely remember that I did update some of them at some point. Maybe I did not have access to all of them at the time. 16:45:56
@hexa:lossy.networkhexa (signing key rotation when)we finally need to get that managed16:51:22
@hexa:lossy.networkhexa (signing key rotation when)so getting these boxes closer to infra would help16:51:28
@hexa:lossy.networkhexa (signing key rotation when)one of the macs on 13.1 / 2.10.2 has 335 GB worth of checkouts in /var/lib/ofborg18:59:10
@hexa:lossy.networkhexa (signing key rotation when)leaving ~10GB for the nix store18:59:21
@hexa:lossy.networkhexa (signing key rotation when)because it apparently fetches everything into an existing repo and never gcs that19:00:28
@hexa:lossy.networkhexa (signing key rotation when)loving the technical debt19:01:03

@hexa:lossy.networkhexa (signing key rotation when)fscking for the thrill of it19:06:06
@hexa:lossy.networkhexa (signing key rotation when)follow me for more silly infra stories 🔔19:06:40
@hexa:lossy.networkhexa (signing key rotation when)nope, will try git fetch --prune first 😄 19:09:07

Auto packing the repository in background for optimum performance.
See "git help gc" for manual housekeeping.
19:19:57
@hexa:lossy.networkhexa (signing key rotation when)will be swapping out the repo, everything else is madness 😄 19:34:09
@ctheune:matrix.flyingcircus.ioChristian TheuneI feel you. i'm currently bisecting the 6.12 series for another v9fs bug that is biting us in our nixos tests ... i started out with getting rate limited by the kernel.org git server because I cloned the repo over and over ... 🙈 ... took a bit to see what's going on, but strace showed me that it was throttled at 1 object per second ... which is ... a tarpit I guess ... 19:43:46
@hexa:lossy.networkhexa (signing key rotation when)that sounds bad, yeah 😄 19:44:15
@ctheune:matrix.flyingcircus.ioChristian Theune well. a colleague pointed out that i can leverage a local repo's working dir with the builtin fetchgit, so that' fast now. still a 25 min cycle and about 13 bisect steps left (with the added complication that there is another v9fs bug in the suspected range that I'll have to skip to see where the bug that is biting us was introduced ... ) 19:45:38
@ctheune:matrix.flyingcircus.ioChristian Theuneso i can't even automate that properly because i need to manually inspect each test failure that always deviates a bit. i guess i need an AI agent /s19:46:20
@raitobezarius:matrix.orgraitobezariusGiven what you are saying, I believe the Lix project already bisected the kernel bug you are looking for, unfortunately, all the commit IDs and answers are trapped behind the kernel lore mailing list browser: https://lore.kernel.org/all/w5ap2zcsatkx4dmakrkjmaexwh3mnmgc5vhavb2miaj6grrzat@7kzr5vlsrmh5/19:51:38
@hexa:lossy.networkhexa (signing key rotation when) Christian Theune: ^ 19:51:57
@ctheune:matrix.flyingcircus.ioChristian Theuneoh?19:52:43
* @ctheune:matrix.flyingcircus.ioChristian Theune checks19:52:46
@ctheune:matrix.flyingcircus.ioChristian Theunefor me it's behind a guru error 😉19:53:10
@raitobezarius:matrix.orgraitobezariusI think you will get a 503 unfortunately19:53:10
@ctheune:matrix.flyingcircus.ioChristian Theuneyeah19:53:14
@ctheune:matrix.flyingcircus.ioChristian Theunedid this break recently / due to a current event? i've been working with it last week I think ... 19:53:45
