 raboof | In reply to @raboof:matrix.org
It's so sad the NAR format doesn't preserve timestamps, so SOURCE_DATE_EPOCH is usually meaningless (i.e. https://github.com/NixOS/nixpkgs/issues/112595). I wonder if it would make sense to introduce a convention where fetchers that can reliably determine the source date could store that somewhere - like in a /SOURCE_DATE_EPOCH file. set-source-date-epoch-to-latest.sh could then pick that up. Is that a crazy idea? https://github.com/NixOS/nixpkgs/pull/256270 | 07:55:39 |
 @trofi:matrix.org | I like when slightly different inputs provide identical outputs. It feels like injecting minor details like timepstamps goes in the opposite direction. But maybe it's just me.
And unrelated point: if you have multiple source inputs (can you?) you will probably need max() of all inputs.
| 10:18:00 |
| raboof | I also like it when slightly different inputs provide identical outputs - though in Nix because of the store paths we already rarely achieve that. if the application is embedding timestamps, though, I like them to be meaningful instead of that random 1970 date. | 10:24:12 |
 atemu12 | raboof: I think they meant that the blah-source path would be different depending on the date | 10:25:31 |
| atemu12 | Usually, you can fetch sources from all kinds of places (or even just copy it from local) and produce the same nix store path | 10:25:59 |
| atemu12 | (When the content matches obv.) | 10:26:18 |
| @trofi:matrix.org | I usually strip out timestamps entirely (or stub out with 9999-01-01). But I can see when sometimes it's not desirable or infeasible. | 10:29:19 |
| atemu12 | raboof: Did you try my idea of the separate output? | 10:33:01 |
| raboof | I couldn't figure out a sensible way to read that out again | 10:34:35 |
