| Lunaphied | Sounds like it's just eval cache brokenness | 21:33:21 |
 just1602 | I probably don't understand the complexity of such setup, but I don't think I understand why there's no tests to catch this kind of things. | 21:37:13 |
| just1602 | Weither it's benchmark / stresstest, some sort of property testing. I mean, there must be ways to properly test that, tho? | 21:37:50 |
 delroth | if evals are too fast then detsys can't sell you flakehub "pre-resolved paths" /s | 21:45:55 |

 KFears (no longer human) | In reply to @whovian9369:matrix.org
If that was for me, the only reference that I could find for the rev string was in my flake.lock for /lix-project/nixos-module
$ rg -N --context=4 621aae0f3cceaffa6d73a4fb0f89c08d338d729e
flake.lock
"locked": {
"lastModified": 1738176840,
"narHash": "sha256-NG3IRvRs3u3btVCN861FqHvgOwqcNT/Oy6PBG86F5/E=",
"ref": "refs/heads/main",
"rev": "621aae0f3cceaffa6d73a4fb0f89c08d338d729e",
"revCount": 133,
"type": "git",
"url": "https://git.lix.systems/lix-project/nixos-module"
},
Hmm, could you check git branch and git tag -a? | 01:03:03 |
| KFears (no longer human) | Another a little sus thing is ref being refs/heads/main. Can you show how you added the entry in flake.nix? Perhaps that might shed some light on the issue | 01:04:39 |
| KFears (no longer human) | As for why CppNix doesn't throw a warning, it's because Lix is using git CLI and CppNix is using libgit2 the C library, I think. I doubt that libgit2 prints any warnings to the terminal anyway, and there are some behavior differences anyway | 01:07:31 |
| KFears (no longer human) | I suspect that CppNix would be just as confused, just silently. But I think the warning is useful, and it would be nice to investigate | 01:08:08 |

| KFears (no longer human) | Hmm, interesting. The entry I'm using is url = "https://git.lix.systems/lix-project/nixos-module/archive/main.tar.gz. Can you check if it works? narHash in flake.lock shouldn't change, unless you haven't updated for a while | 01:14:42 |
| KFears (no longer human) | Oh, I think you'll have to update specifically the module input before checking narHash, because it seems you're missing 1 commit

| Whovian9369 | Would I want to nix flake update before or after I swap out the URL? :P | 01:18:52 |
| KFears (no longer human) | Before. I'm not sure if it will reload automatically or you'll also have to run it after updating | 01:19:34 |
| Whovian9369 |
I'm not sure if it will reload automatically
I bet nix flake update would yell since it doesn't match.

| Whovian9369 | Well it'd update the hash, I mean. | 01:20:39 |
