 John Ericson | it is unclear to me whether it is possible for two threads to be messing with a goal at once | 18:49:24 |
| John Ericson | but if the goal is removed from worker, and from waitees/waiters, then I don't think another thread can find the goal very easily | 18:49:50 |
| John Ericson | If Robert is busy today, well we at least have the Nix meeting tomorrow | 18:50:11 |
 Las | You can’t move around the worker interactions freely because you might mutate the data structures that are being iterated over at the same time | 18:50:38 |
| Las | Maybe not an issue there though | 18:50:48 |
| Las | Goals are single threaded | 18:51:12 |
| Las | Maybe in 2035 Mobile Element will support threads so I can respond it a thread | 18:52:03 |

 emily | (Element X does) | 18:54:10 |
 K900 | Normal Element does too | 18:54:27 |
| K900 | Though we generally try to not use threads in public rooms because there's still clients that don't display them properly or at all | 18:54:45 |
| Las | I can’t make one on iOS I think? | 19:03:25 |
| John Ericson | I never saw any mutex or something that made it obviously single threaded, but yes I believe that is the intent | 19:08:15 |
| Las | Sealed state was a mistake | 19:14:37 |

 jade_ | FYI in re https://git.lix.systems/lix-project/lix/issues/750, it seems like nixos/nix fixed this by accident, but still has some amount of an underlying bug (or at least poor documentation of the treatment of the underlying bug): the info.path in this spot is the bad 9hagx value
https://github.com/NixOS/nix/blob/3032512425a09fc58f2d658442043894e0aab256/src/libfetchers/tarball.cc#L74-L83

| jade_ | (and it does not seem like it can be trivially changed to recursive hash mode there, since that breaks a bunch of observable behaviour. i have no idea how this is supposed to behave, but it seems like a really quite large bug) | 19:01:44 |

| jade_ | okay update: i can confirm that nixos/nix master emits that 9hagx path into the store and then additionally gets the q9prs one | 21:56:28 |
| jade_ | * okay update: i can confirm that nixos/nix master emits that 9hagx path into the store and then additionally makes the q9prs one | 21:56:33 |
| jade_ | that seems at least inefficient if the files are large | 21:56:41 |
