 Tristan Ross | Oh great, I just ran into that swift bug.... | 04:18:18 |
 samasaur | I'm kicking off a bisect for that Swift bug with jj bisect run --range b579d443b37c9c5373044201ea77604e37e748c8..a1bab9e494f5f4939442a57a58d0449a109593fe -- nom build -A swift (commits grabbed from Hydra). I think it'll be a couple days before I can investigate but maybe that will give enough time for this bisect to finish, given that it will be rebuilding the world a lot | 06:57:29 |
| samasaur | (I haven't used JJ's bisecting before, so if anyone has and sees anything wrong with that command let me know. I think I got it right but I'm not entirely sure) | 06:58:01 |

| samasaur | I did not realize how much stuff in nixpkgs depends on Swift on Darwin | 07:04:50 |
| samasaur | oh also Randy Eckenrode do you know if there's anything weird you have to do to get llvm-symbolizer to work? I tried setting LLVM_SYMBOLIZER_PATH to lib.getExe' libllvm "llvm-symbolizer" but that didn't seem to get picked up | 07:08:58 |
 Randy Eckenrode | In the swift-frontend stack traces? I don’t think I’ve ever gotten it working. | 10:49:14 |
| Randy Eckenrode | Admittedly, I don’t think I tried more than setting the path in the terminal. | 10:49:58 |
 Ihar Hrachyshka | samasaur: in my experience bare automated bisects that don't consider WHY a failure happens are not very reliable in nixpkgs. it fail in "bison" or "sqlite" or whatever and assume that it's a sign of swift being broken. | 14:50:58 |

| Ihar Hrachyshka | (writing a script that captures the cause may or may not be easy; if too hard or just lazy, I suspect a AI agent could be instructed to run the bisect loop for you... never tried it myself before though) | 14:55:38 |
 Austin Horstman | everytime swift breaks it feels catastrophic to my setup lol | 14:59:55 |
| Austin Horstman | mixed with firefox not building / caching my macbook is in a weird state lol | 15:00:50 |
| Ihar Hrachyshka | sorry for the latter. fwiw one can take firefox and thunderbird from release branches, they are the same version most of the time. | 15:01:38 |
| Austin Horstman | is it same version just without lto? | 15:01:57 |
| Ihar Hrachyshka | yeah, lto was not backported. | 15:02:07 |
| Austin Horstman | ah, good to know | 15:02:12 |
| Austin Horstman | thanks | 15:02:15 |
| Ihar Hrachyshka | did it get better btw? we merged the hydra bump. | 15:02:21 |
| Austin Horstman | i hadn't seen hydra using the new timeout yet ( i haven't checked in a couple days) | 15:02:40 |
| Austin Horstman | my local builds stopped completing and just hang after a certain part of the build | 15:02:56 |
| Austin Horstman | https://hydra.nixos.org/build/320487707 | 15:03:34 |
| Ihar Hrachyshka | there was thunderbird build with the new timeout I think | 15:05:23 |
| Ihar Hrachyshka | https://hydra.nixos.org/build/320117237 | 15:05:45 |
| Ihar Hrachyshka | not sure why it says 0s duration though, haven't dug deeper | 15:05:56 |
| Austin Horstman | yeah, just saw the 0s and got super confused lol | 15:06:21 |
| Ihar Hrachyshka | the log also seems interrupted? | 15:06:49 |
| Austin Horstman | https://hydra.nixos.org/build/319577871/nixlog/2 shows the full log i think? | 15:07:03 |
| Austin Horstman | maybe not. i don't see stripping stuff | 15:07:19 |
| Ihar Hrachyshka | but I can nix build --file . thunderbird from the tip and it gives me what looks like an .app :) | 15:07:48 |
