 emily | (the Preserves textual format is also a superset of JSON, so in terms of being able to ingest things in a familiar format to then canonicalize it works well. but again many understandable reasons to pick something else, just giving an overview of the space as I see it) | 17:04:33 |
 Robert Hensing (roberth) | John Ericson: did we have an issue on this topic yet? Couldn't find one | 17:06:35 |
 John Ericson | @roberthensing:matrix.org: for new drv format? | 17:24:42 |
| John Ericson | Not actually sure | 17:24:54 |
| John Ericson | Also FYI https://github.com/facebook/buck2/issues/866 | 17:25:21 |
| John Ericson | I sent to @edef1c too | 17:27:02 |

John Ericson: I've suggested to treat the Nixpkgs "fix" for the CA placeholder issue (no storedir prefix) as a workaround as ca-derivations is experimental https://github.com/NixOS/nixpkgs/pull/386774#pullrequestreview-2660479310 builtins.placeholder has the same "issue", though i like them not being /nix/store-prefixed because it disambiguates that their format is unstable | 17:31:38 |
| Robert Hensing (roberth) | That one isn't experimental, so we'd need a very very good reason to change that anyway | 17:33:35 |
| emily | I don't suppose Nix strings support NUL bytes in them so that we could properly separate the namespace from actual filesystem paths? in the same way abstract Unix sockets do | 17:33:47 |
| Robert Hensing (roberth) | Also isn't user-handled as much as outputs are | 17:34:04 |
| Robert Hensing (roberth) | Evaluator strings are C strings. This could be changed to something with a length, but we're not in a hurry. I guess one of those separator control characters could serve the same role, but I feel that it'd be weird to do any of that (regardless of choice of byte value) | 17:35:50 |
| emily | NUL is the only byte that is actually guaranteed to not be allowed on Linux anyway (though of course other platforms exist too) | 17:38:44 |
| emily | so no advantage to anything else | 17:38:48 |

 ElvishJerricco | I'm going to make this comment here because I think it is one of the most important things I've said in the world of NixOS. Please read this comment: https://discourse.nixos.org/t/determinate-nix-3-0/61202/57 | 21:33:50 |

 fzakaria | Trying to figure out dynamic derivations;
I'd appreciate some tips | 06:07:58 |
| fzakaria | Hitting some weird road blocks with what I think would work. | 06:08:14 |
| fzakaria | Like:
warning: Ignoring dynamic derivation /nix/store/8apg4x2xbcx83xc0p1jk1qdiihkmhjyg-hello-2.12.1.drv.drv^out while querying missing paths; not yet implemented
error: Building dynamic derivations in one shot is not yet implemented.

 tomberek | You might need a wrapping drv for now. | 06:20:45 |
| fzakaria | Here is my strawman https://pastebin.com/wnHmj4pW | 06:46:30 |
| fzakaria | i think it's a wrapping drv? | 06:46:36 |

| deprecated, moved to @poz:poz.pet | hey, I added the modulo operator to nix: https://github.com/NixOS/nix/pull/12617
I'd be grateful for any reviews, likes under the PR or advice on how to get it merged quick (I've seen a lot of PRs be untouched for a long time and I'm not hopeful for mine) | 12:36:10 |
