 emily | so if it's just termios… are non-interactive shells not affected? | 21:35:35 |
| emily | i.e. actually Nix binfmt builders should be fine and it's just QEMU user emulation of interactive terminal programs? | 21:35:43 |
| emily | that seems niche enough that it's probably not a blocker IMO | 21:35:49 |
| emily | OTOH Gentoo is patching I guess? | 21:37:59 |

so if it's just termios… are non-interactive shells not affected? non-interactive programs are not affected. the top level nix build run in a pty and i hope those are unaffected? | 04:25:05 |
| dramforever | and running cross-arch containers feels like it's, quite common among qemu-user users | 04:25:55 |
| emily | sounds like the projected impact shouldn't be world-ending even if we wait for upstream and they're a bit slow at least? | 05:11:56 |
| emily | I've used qemu-user a nontrivial number of times in my life but I think almost never to run interactive terminal programs | 05:12:31 |

sounds like the projected impact shouldn't be world-ending even if we wait for upstream and they're a bit slow at least? it shouldn't be hard to have users manually overlay qemu with the patches either | 08:23:52 |

 Fabián Heredia | I am hopeful that it will be upstreamed within 2 weeks now that several distros have picked it up and the patches have been sent on the correct channel.
Only blocker could be authorship/license due to the patches being submitted by someone who isn't the author | 00:32:50 |
| Fabián Heredia | Unsure about what happened but seems like there were about >50k rebuilds on nixpkgs:unstable from the previous eval to the current eval | 04:52:39 |

 whispers (it/fae) | maybe related: some builds i ran on master were trying to build cargo for aarch64-linux, which absolutely should not have needed a rebuild without staging cycle | 04:53:40 |

| whispers (it/fae) | * maybe related: some builds i ran on master a few hours ago were trying to build cargo for aarch64-linux, which absolutely should not have needed a rebuild without a staging cycle. so something deep in the dependency tree changed somehow | 04:55:36 |
| whispers (it/fae) | looking at hydra, it seems like cargo (probably some dependent?) had a rebuild on every platform besides x86_64-linux | 05:05:00 |
| whispers (it/fae) | https://github.com/NixOS/nixpkgs/pull/472376 probably this PR | 05:06:15 |
| Fabián Heredia | weird that x86_64-linux would be 0 rebuilds and ofborg/eval also indicates 0 rebuilds 😱 | 05:07:35 |

| Fabián Heredia | Yeah currently x86_64-linux chilling | 05:08:31 |
| whispers (it/fae) | * https://github.com/NixOS/nixpkgs/pull/472376 maybe this PR? | 05:10:35 |
| whispers (it/fae) | Redacted or Malformed Event | 05:17:28 |
| whispers (it/fae) | * if i'm right and it is that pr, i have a guess at how this happened. i wonder if https://github.com/NixOS/nixpkgs/pull/464707 made this PR become a mass-rebuild (once it reached master with the recent staging-next merge) between the time of the initial CI rebuild calculation/label application and merge time | 05:18:23 |

| whispers (it/fae) | * i don't fully understand this interaction with RUSTFLAGS but it may also have something to do with https://github.com/NixOS/nixpkgs/pull/464707 | 05:42:25 |
| whispers (it/fae) | * https://github.com/NixOS/nixpkgs/pull/472376 maybe this PR?
