I might take a crack at beginning to fix this at least for nix develop, I've been doing a little bit of work on that code recently. This is very cross-cutting tbh | 05:03:57 |
| K900 | I think you'd have to start at nixpkgs | 05:04:08 |
| K900 | And probably structuredAttrs? | 05:04:30 |
 blitz | I almost have a prototype of attic that solves this for now by calling the Nix CLI. Will check gorgon once I have something working. One last obstacle: Is there a stable way to list the signatures of a store path without resorting to nix path-info (which has changed output formats a couple of times...) ? | 07:35:48 |
 Lisanna | Oh for sure, the whole point would be to make nixpkgs do the heavy lifting here | 08:11:59 |
 zoë (she/her) | is there any way to see previous build logs after rebuilding a derivation? kind of like journalctl's --boot option to see previous boot logs instead of the current one. it seems like nix overwrites them now; would there be any obstacle to renaming them to foo.drv-1, foo.drv-2, etc when a new build is launched? | 08:41:12 |

 boop-north | I did sudo -i nix upgrade-nix and now can't run commands related to nix. `nix/var/nix/profiles/default/bin exists in path | 09:56:08 |

 Lotte (it/its)/Cinny (she/her) θΔ& | interesting. a path can be garbage collected between the time a build gets started and the time the build runs?
at least i saw that earlier today. some rust crate was complaining about its dependencies being missing and not the typical hydra complaints about some specific store paths not being present locally | 11:35:39 |
 raitobezarius | is your daemon still running? | 11:36:42 |
| zoë (she/her) | that sounds like a bug? on the contrary, a few months ago when i tried this (either on cppnix or lix, can't remember), it wouldn't collect/delete dependencies of running builds or open shells | 11:38:09 |
| Lotte (it/its)/Cinny (she/her) θΔ& | unfortunately due to the build having been overwritten by a retry i can’t provide logs of it happening | 11:38:58 |
| zoë (she/her) | or maybe i'm misunderstanding what you mean by "build started" and "build runs" | 11:39:04 |
| zoë (she/her) | haha exactly what i was complaining about a few messages above :^) | 11:39:30 |
| zoë (she/her) | * haha exactly what i was complaining about a few messages above :p | 11:39:42 |
| Lotte (it/its)/Cinny (she/her) θΔ& | https://hydra.chir.rs/build/72679#tabs-buildsteps i guess there’s this | 11:39:49 |

At least in cppnix we’ve been trying to squash those issues. Not sure Lix fixed all of those | 11:40:01 |
| Lotte (it/its)/Cinny (she/her) θΔ& | i should probably just add hydra to the conflicts of the gc | 11:40:09 |
| Lotte (it/its)/Cinny (she/her) θΔ& | Aborted: [31;1merror:[0m dependency '[35;1m/nix/store/6nar2q94jybd9lgsa1s41zwk6q2d5il6-rustblake2-0.10.6-lib[0m' of '[35;1m/nix/store/01dqlw7c55b7icy4zx69mqvvgv50fxkm-rustlibsignal-message-backup-0.1.0.drv[0m' does not exist, and substitution is disabled
is what i would expect to happen | 11:40:23 |
| Lotte (it/its)/Cinny (she/her) θΔ& | the failed line above was the juicy one | 11:40:28 |
| Lotte (it/its)/Cinny (she/her) θΔ& | because that was full of errors where dependencies couldn’t be found by rustc | 11:40:57 |
| boop-north | I just reinstalled lix. When I ran it, it was. Afterwards I'm not sure | 11:41:32 |
| Lotte (it/its)/Cinny (she/her) θΔ& | which implies at least to me that between the time the build was started and the time rustc was run the store path got deleted | 11:41:51 |

 mjm | lix is now in nixos-unstable, what's the best way to use it in a NixOS config? | 15:47:41 |
