 Arian | Actually they use it for not just eval and also build... But just for eval is already interestinh | 18:17:52 |

 eveeifyeve | Eelco: It's really interesting looking through the movement on NaN canonicalization wasm issue, I am not too exactly some user choose to make it required and some don't. It might be a good to get some idea from the wasm developers (if it's not required, The question is what is it's use.). | 13:14:56 |

 vcunat | I noticed when looking around Hydra that now tests.nix-copy very often fails, even on multiple older Nix branches, e.g. https://hydra.nixos.org/build/325164327#tabs-buildsteps | 07:04:53 |

 Sergei Zimmerman (xokdvium) | I’ve seen a lot of nixosTests timing out because backdoor service doesn’t spin up or something along those lines. It seems like something borked with vm tests machinery | 08:15:32 |
| Sergei Zimmerman (xokdvium) | In nix-copy specifically I think we just lack some synchronisation between server/client | 08:18:18 |
| Sergei Zimmerman (xokdvium) | This seems like a smoking gun:
client: waiting for Password: to appear on screen
server # [ 356.772255] sshd[897]: Timeout before authentication for connection from 2001:db8:1::1 to 2001:db8:1::2, pid = 1023

 Jens Petersen | I am getting this warning/error on Fedora with nix-2.34:
warning: unable to download 'https://channels.nixos.org/flake-registry.json': Problem with the SSL CA cert (path? access rights?) (77) error adding trust anchors from file: ; using cached version
Any ideas? (nix-2.33 seems okay) | 10:00:16 |
| Sergei Zimmerman (xokdvium) | Hm, that’s with the release binaries, right? Wonder why the path is empty | 10:43:38 |
| Jens Petersen | Sergei Zimmerman (xokdvium): no it is a fedora build | 11:15:45 |
| Jens Petersen | Okay thanks Sergei Zimmerman (xokdvium) - seems i need to set ssl-cert-file now | 11:29:57 |
| Sergei Zimmerman (xokdvium) | For onlookers, Jens shared that fedora 44 is removing the default PEM certs https://fedoraproject.org/wiki/Changes/droppingOfCertPemFile | 11:42:22 |
| Sergei Zimmerman (xokdvium) | Not a nix change | 11:42:55 |

 dramforever | so if i have multiple nix processes on the same --store that each may build stuff and/or run gc, are these supposed to be synchronized? | 15:17:05 |
| dramforever | i've been playing around with gc races and i'm getting all sorts of exciting errors by doing this, even with https://github.com/NixOS/nix/pull/15469 applied | 15:17:36 |
| dramforever | the recipe:
- run two of
while nix -vvv --min-free 512T --no-auto-optimise-store --store teststore/ build --no-link nixpkgs#pkgsCross.riscv64.hello ; do : ; done
- run one of
while nix -vvv --min-free 512T --no-auto-optimise-store --store teststore/ store gc; do : ; done
put them each in a tmux pane and watch the chaos unfold
