 vcunat | * It's possible. Or at least I don't know anything disproving that. | 20:27:51 |
 John Ericson | I was told this sort of central bottleneck was the sort of thing it was focused on | 20:28:01 |
 Sapii | Ok thank you! i see 14 out of 201 still pending for unstable so its getting prrety close! | 23:06:17 |

| vcunat | I don't get what numbers you mean. Either way, the channel should update within an hour now. | 04:46:15 |
| Sapii | Ahh they are the tests https://hydra.nixos.org/job/nixos/unstable/tested#tabs-constituents, sorry for not specifying | 15:19:32 |
| vcunat | They're not relevant for this. Channel bump waits for all tests, not just for this tiny subset. | 15:20:27 |
| vcunat | (we have thousands of test jobs) | 15:20:46 |
| vcunat | * (we have thousands of test jobs; the current nixos-unstable rebuild was about 20k jobs) | 15:21:11 |

 Mic92 | John Ericson: https://github.com/NixOS/hydra/pull/1658 did check on staging hydra, seems to work fine | 21:51:38 |
| Mic92 | only had to extend this environment variable so it works with the hydra module for deploying s3 creds | 21:52:08 |

| John Ericson | Great! Queued | 01:43:59 |
| John Ericson | Have we tested mac builders yet? | 01:44:24 |
|  Alesya changed their display name from Alesya Huzik to Alesya. | 01:49:30 |
|  sebastianrasor joined the room. | 02:19:40 |
| Mic92 | John Ericson: not yet. I also found an issue this morning. I migrated staging hydra now to a new machine. If we see failures there, it means something is off and needs to be fixed. I am currently testing & deploying this: https://github.com/NixOS/hydra/pull/1659 | 08:32:45 |
| Mic92 | we can potentially have the nix build in staging hydra to get mac builds | 08:33:30 |
| John Ericson | Mic92: thanks for taking a look! | 19:31:47 |
| Mic92 | I am now monitoring: https://staging-hydra.nixos.org/eval/1 | 19:33:38 |
| John Ericson | ok cool | 19:34:05 |
| John Ericson | Mic92: do you think we could write hydra regression test for some of these? | 19:34:23 |
| John Ericson | I am surprised the fixed output paths were busted an the systems tests didn't fail, for example. that is weird | 19:34:50 |
| Mic92 | John Ericson: I think so. I have one regression test already in the upstream crate, but there might be no e2e test in hydra itself. | 19:36:00 |
| John Ericson | do we just need to build a fixed ouput derivation? | 19:36:38 |
| Mic92 | yes, file:// might work for this, otherwise a small webserver | 19:38:17 |
| John Ericson | OK working on a test | 19:45:26 |
| Mic92 | John Ericson: maybe have a look around what other kinds of derivations we are not covering | 20:00:46 |
| John Ericson | ok | 20:01:30 |
| John Ericson | also heard you | 20:01:34 |
| John Ericson | FYI I added a new check derivation to make sure the perl schema is up to date | 23:58:43 |

| Mic92 | I discovered this class of reproducibility issues while looking at staging-hydra: https://github.com/NixOS/nixpkgs/pull/509752 | 10:05:24 |
