 Winter | do we want to simply remove that note from the readme, or change nrWorkers to actually default to nproc? | 20:12:19 |
 ma27 | my personal preference would be to keep the behavior as-is and just fix the docs. | 20:15:45 |
| Winter | gotcha | 20:45:11 |
| Winter | learning that n-e-j doesn | 20:45:15 |
| Winter | ...'t die on sigpipe and groaning | 20:45:23 |
 raitobezarius | i think there's a bunch of CL improvements from aloisw on n-e-j | 21:56:52 |

 aloisw | SIGPIPE is not in it though. Also it seems like the entirety of Lix just ignores it completely. I think the best way forward would not be to special-case it in nix-eval-jobs, but to treat as an interrupt like SIGTERM and SIGHUP. | 05:59:10 |
| Winter | i believe i only looked at nix but it appears that they’re not explicitly ignoring it at least, instead just saying to use the OS’ default signal handler for it? | 06:15:06 |
| Winter | and yeah, agreed | 06:15:10 |
| Winter | guess i could write a patch for that pretty easily | 06:15:40 |
| Winter | once i wrap my head around the current state of affairs described above | 06:15:49 |

i believe i only looked at nix but it appears that they’re not explicitly ignoring it at least, instead just saying to use the OS’ default signal handler for it? https://git.lix.systems/lix-project/lix/src/commit/78bdc60c11031d2293b2e77a0e44140ff7b88f12/lix/libutil/signals.cc#L189-L197 | 07:25:58 |
| aloisw | The solution I imagined above was just adding SIGPIPE here: https://git.lix.systems/lix-project/lix/src/commit/78bdc60c11031d2293b2e77a0e44140ff7b88f12/lix/libutil/signals.cc#L119 | 07:26:54 |
| aloisw | Of course that's not going to work because SIGPIPE is only sent to the writing thread. | 11:45:10 |

 Grimmauld (any/all) | Quick heads-up:
I believe https://git.lix.systems/lix-project/lix/src/commit/e101400359558ec89f0a3afa29631ca1b6546fd3/lix/libutil/processes.cc#L20-L22 should be unconditional. On glibc gcc this header is included implicitly. On musl llvm, that include is needed or otherwise SYS_capset (https://git.lix.systems/lix-project/lix/src/commit/243836ed0a0b963eebd033d109e6cb817d67fde4/lix/libutil/processes.cc#L414) is undefined. | 08:49:40 |

Seems like function tests need to provide a sensible default for TMPDIR if it's not set

| raitobezarius | Can you open an issue with this trace so I don't forget about it? Thanks! | 00:03:55 |

|  olivia changed their profile picture. | 00:23:19 |
| Sergei Zimmerman (xokdvium) | Also any clue as to what's going on here? https://buildkite.com/lix-project/lix/builds/5888/steps/canvas?sid=019a8f19-65cf-4acd-9593-5d6bcd790abf#019a8f19-668b-4cbb-99c2-e68a72269606/18-32
The error message is coming from the host lix and not the one that's being built? Seems fucked | 00:25:14 |
| raitobezarius | I am going to take a look, I hope I didn't fuck up something with my recent infra work | 00:28:24 |
| raitobezarius | Normally I didn't touch this host neither its daemon setup | 00:28:35 |

This new mode for GPU support got merged last week.
You might wanna update the README, that speaks about NixGL (only) | 07:53:37 |

| 522 it/its ⛯ΘΔ | or | 11:23:19 |
| 522 it/its ⛯ΘΔ | does lix's readme have a mention of nixgl? | 11:23:33 |
