 Vladimír Čunát | Hmm, so both CPU and RAM usage would be significantly worse. I thought of doing this for the tarball job instead, but the RAM requirements wouldn't most likely become a problem with the current infra. | 08:05:06 |

Is there a case that would have been caught with 2.3 that wasn't? We already had path interpolation slip into master before: https://github.com/NixOS/ofborg/issues/612 | 08:55:27 |

 piegames | Hi, I'm currently implementing RFC 127 in https://github.com/NixOS/nixpkgs/pull/177272. There is this comment in check-meta.nix, "!!! reason strings are hardcoded into OfBorg, make sure to keep them in sync". So I'd like to coordinate this change with the OfBorg maintainers | 19:22:09 |
| 16 Jul 2023 |
| piegames | So I did some keyword search through the OfBorg code base, the only relevant thing I found is https://github.com/NixOS/ofborg/blob/released/ofborg/src/outpaths.nix#L28-L34, which does not look like it needs updating | 08:02:16 |
| piegames | On the other hand, the implementation pull request causes OfBorg internal errors (according to the label it added), so clearly there is something weird going on here | 08:02:48 |
| piegames | Where do I find the OfBorg error logs? | 08:04:56 |
 Lily Foster | In reply to @piegames:matrix.org
Where do I find the OfBorg error logs? I'm not sure where the ofborg logs are, but if it did fail in outpath caculation, you could try to run that manually with the instructions at https://github.com/NixOS/ofborg#running-meta-checks-locally (I just hope you have a system with 60+ GiB of RAM though...) | 10:55:04 |
| piegames | Unfortunately that is not an option for me then | 11:00:21 |
| Lily Foster | In reply to @piegames:matrix.org
Unfortunately that is not an option for me then So I'm running some stuff manually for you and it looks like ofborg may be failing in the stdenv check, which runs with a merged stderr+stdout to attempt to get the stdenv output path (but this PR throws a bunch of maintainless warnings to stderr) | 11:18:20 |
| piegames | Thanks. | 11:19:26 |
| Lily Foster | (I feel like ofborg should probably not be merging stderr and stdout when keep_stdout is passed to nix::Nix::run but I do not know much on why that is like that to begin with) | 11:19:59 |
| piegames | I simply forgot to set the maintainerless default to "ignore" again, but actually that's a good thing because there definitely will be warn-by-default things in the log in the future | 11:20:00 |
