 Matej Urbas | Hi Arian! You probably got to the bottom of this problem by now, right?
For the future though, I just added this S3 logging change to Nix: https://github.com/NixOS/nix/pull/12007
This will print an ID which you can use to find more information in CloudWatch. | 19:09:19 |

 Robert Hensing (roberth) | Perhaps we should adopt the "oldstable" name? I've seen that name pop up during the support window overlap before | 13:59:55 |
 p14 | I just hit what looks like this old issue: https://github.com/NixOS/nixpkgs/issues/138157
It appears to repro on nixpkgs staging with nix 2.24.10 doing nix develop -f . hello. I get:

| p14 | I see a handful of issues of this style open against nix as well. https://github.com/NixOS/nix/issues?q=is%3Aissue+json+json.exception.parse_error+is%3Aopen
Is this a recently introduced stdenv issue | 14:44:37 |
| Mic92 | p14: https://github.com/NixOS/nix/pull/11921 | 15:53:27 |
| p14 | This is while running 'nix develop' though, there is no indication of any build taking place | 15:54:37 |
| p14 | * This is while running 'nix develop' on any package in staging though, there is no indication of any build taking place | 15:54:55 |
| Mic92 | p14: I have the feeling if all packages are doing that, we should also fix this in nixpkgs. It should not echo invalid json | 16:11:30 |
| Mic92 | Do you know what change introduces this? | 16:11:46 |
| p14 | In reply to @joerg:thalheim.io
Do you know what change introduces this? I do not, sorry, my time budget blew and I am now afk for a bit. Seems master is ok but not staging. | 16:16:50 |
| Mic92 | Maybe give a heads up in the staging channel at least. | 16:17:23 |
| Mic92 | The pull request is only improving the error message, but not fixing the root cause, which is on the nixpkgs side. | 16:17:55 |
 Lach | I believe I have once fixed illegal utf8 logs, it is not correct to skip those lines entirely: https://github.com/NixOS/nix/pull/5160 | 17:46:50 |
| Lach | There would always be those errors on nixpkgs side, because builder scripts aren't forced to output utf8-only logs, yet nix is converting those logs to json, and json library only expects utf8 strings | 17:50:02 |

 rhelmot | Is it even possible to use garbage collection with a diverted store? No matter what I do, gc roots get created as /nix/store symlinks and the garbage collector deletes out of /nix/store | 03:47:06 |

 tomberek | That feels like a bug. | 20:10:19 |
| 9 Dec 2024 |
| Mic92 | Lach: isn't json supposed to be either unicode or ascii with escaped chars? | 12:16:33 |
| Lach | Ascii with escaped chars shouldn't include invalid unicode sequences (Unpaired surrogates are allowed at max), yet builder scripts might output invalid unicode sequences, and nix worker protocol requires this output to be encoded to json, which is impossible in general, invalid utf-8 sequences must be replaced | 12:48:07 |
