 DolceTriade | The parts that were failing were part of a custom binary cache | 19:14:29 |
 raitobezarius | so a misbehaving binary cache perhaps? | 19:18:36 |
| raitobezarius | still, we shouldn't crash because of that | 19:18:52 |
| DolceTriade | Yes, that seems likely. | 19:19:55 |
| raitobezarius | if we can get access to it and have a reproducer in a bug issue, we can look into that | 19:20:41 |
| raitobezarius | we would debug it via gdb and look into the state machine | 19:20:49 |
| DolceTriade | We're using attic as our binary cache and I guess we discovered that one of binary cache uploads failed. Dunno how to reproduce this. I can try to build a reproducer. | 19:22:20 |
| DolceTriade | * We're using attic as our binary cache and I guess we discovered that one of binary cache uploads failed. Dunno how to reproduce this. I can try to build a reproducer that simulates a similar situation | 19:22:36 |

 Winter | running into the same silly “writeTextFiles from my system build are taking longer than i expect to build,” where “longer than i expect” = like a second per drv… 🤨
can reliably ish repro at least… but still very weird

| Winter | am i going insane, or are NixOS system closures Just Like That | 02:07:25 |

Sandbox setup time grows with respect to the number of derivations that you are building overall | 06:32:46 |
| raitobezarius | As you have more derivations, forking takes more time even if the derivation is trivial to build | 06:33:20 |
| raitobezarius | It's on our radar to fix this | 06:33:28 |
| raitobezarius | Because it's impossible to build 1M of trivial drvs due to that | 06:33:38 |
 Sofie 🏳️⚧️ (she/her) | btw, thank you so much for build-vm! nixos really plays well with Qemu | 08:36:03 |
| raitobezarius | lmk once you have one, i'm interested | 08:54:46 |
