 flokli | There's too many workarounds for problems with the schema. | 11:37:52 |
 jaen | Yeah, that's true. I've just meant that "crystals" would have to come with input scopes from the get go, as it would make those workarounds (such as they are) not viable. | 11:39:52 |
| flokli | I'd be happy to read and give feedback on a design proposal. | 11:41:15 |
 aleksana 🏳️⚧️ (force me to bed after 18:00 UTC) | Idea: We should detect a "minimum syscall permission set" that allows Nix to work and make both hydra and ofborg follow this specification. Currently nested containers (for example, nix-build in systemd-nspawn) cannot pass the checkPhase of some packages, but we don't fix it because CI isn't set up as such. | 12:55:28 |

most of the logic in that file is to properly adjust stringLength output to the post-substitution paths, even, the actual logic there is like three lines Just asking out of curiosity: Why was string length important to you?
I don't see when that would matter with how they are usually used, so I figure maybe you are doing something unusual. 😅 | 15:21:26 |

I don't see when that would matter with how they are usually used, so I figure maybe you are doing something unusual. 😅 it's for calculating the length of the final string, post-substitution, so it can be properly seated into the tarball | 12:39:20 |

Currently nested containers (for example, nix-build in systemd-nspawn) cannot pass the checkPhase of some packages, but we don't fix it because CI isn't set up as such. The nix sandbox with seccomp defines the minimum set of syscalls already. | 13:24:18 |
| Mic92 | Issue is that your containers syscall set is smaller than set | 13:24:56 |

Issue is that your containers syscall set is smaller than set We should at least throw a warning I guess? | 13:25:26 |
| Mic92 | How would you implement that? | 13:25:50 |
| Mic92 | This something you can do in a test derivation. But I don't think nix should test this | 13:26:55 |

| Benno Fünfstück | is there some way to force a value in Nix but then later deallocate everything allocated by this forcing? Or is that fundamentally impossible due to how the evaluator works right now? | 15:23:57 |
| Benno Fünfstück | perhaps I could abuse fork for this... hmm | 15:24:40 |
 emily | well, you can drop all references to it and let it get GC'd | 15:29:27 |
| emily | but generally forced thunks don't go back to being thunks in lazy languages | 15:29:44 |
| Benno Fünfstück | ah yes I suspected this might be the case. thanks | 15:31:48 |
