 baloo | like, by merging the patch upstream, there is some "acceptance" (wrong word) the patch is needed. So it feels like a pure philosophical limitation ... and I don't get it. | 18:57:04 |
| baloo | (just trying to understand things going on here, not trying to be an ass or something) | 18:57:46 |
 tomberek | i don't know, i think it'd be fine for most, but Nix is a bit special and so a lot of the normal committers are hesitating. I'm not aware of any expressed objections. | 18:58:47 |
| baloo | I've been chasing the issue for a month now, and seeing it drag when it should be fixed. I don't know, bothers me | 18:58:51 |
| tomberek | We can post it in "Nix Hackers" | 18:59:39 |

| tomberek | baloo: This indicates that more than that PR is needed: https://github.com/NixOS/nix/issues/5089#issuecomment-917606674 | 01:01:13 |
| baloo | i mean | 01:02:32 |
| baloo | sure | 01:02:33 |
| baloo | still trying to manage my frustration here :) | 01:03:10 |

| @bew:matrix.org | Hello, I'm reading https://github.com/wmertens/rfcs/blob/master/rfcs/0017-intensional-store.md and there's something I don't understand:
In the part A note about reproducibility, it says:
There is no need for a given $out to always generate the same $cas. [...] There is no obligation that a single $out only stores a single $cas entry.
| 22:26:23 |
| @bew:matrix.org | How is that possible? | 22:26:33 |
| @bew:matrix.org | How can a single $out generate multiple $cas ? | 22:27:35 |
| @bew:matrix.org | (if there's a better room for this question, please tell me 🙏) | 22:28:07 |
| tomberek | bew: Basically that is saying that the builds don't have to be reproducible for the intentional store to work. (of course it helps) | 23:07:25 |
| tomberek | You and I can build the same $out, but get different $cas's. This isn't ideal, but that's why there is a mapping from 1 $out to possible multiple $cas's. | 23:09:12 |
| 23 Sep 2021 |
 @afontain:gnugen.ch | what's $cas ? | 10:14:18 |
| @afontain:gnugen.ch | or is it $cas's ? | 10:14:31 |
 @timdeh:matrix.org | Content Addressed Store | 14:16:22 |
| @timdeh:matrix.org | tl;dr: It's an experimental feature which places packages in the nix/store based on a hash of their output rather than their input | 14:16:51 |

| @afontain:gnugen.ch | ok, thanks | 15:31:36 |

 j-k | in a non-nix context on your typical distro is it possible to have a reproducible binary that has dynamic links?
For achieving that reproducability I guess it'd be safest/easiest to use a statically linked gcc? If you're not using a statically linked gcc I guess you would need to keep track of your gcc version and glibc version? | 11:25:10 |
