 cransom | imo, i try not to stack bandaids. if you have to go through code change anyway and the end result is prometheus, going through an intermediate statsd step is cumbersome. regardless of if it's perl or not. | 15:50:37 |
 @grahamc:nixos.org | I agree cransom | 17:29:48 |
| @grahamc:nixos.org | I don't suppose you would be interested in making a Prometheus version of that Plack middleware? | 17:30:12 |
| @grahamc:nixos.org | it isn't actually so complicated to write, but I'd want to write tests for it too, and I think it'd take more time than I can really commit :( | 17:30:31 |

 andi- | Do the hydra tests have any concept of test fixtures? Just looking at writing a test around a jobset and so far the tests look like they depend on each other (being executed in order). Usually I'd just setup a jobset and discard of it after my test again. | 14:28:49 |
| andi- | cole-h: ^ you wrote most of the code there :D | 14:29:02 |
| @grahamc:nixos.org | every .t file runs its own postgres database | 14:31:39 |
| @grahamc:nixos.org | * every .t file runs its own postgres server | 14:31:47 |
| @grahamc:nixos.org | and hydra-init runs then you have to create everything from scratch from there | 14:32:00 |
| andi- | Ah nice, I'll just add another file then. | 14:34:08 |

| Valodim | https://hydra.nixos.org/search?query=aaaa it seems that just about any search term that isn't very short will run into query timeouts. also, "aaaa" finds results with four as anywhere in the Job name. is the hydra search doing an unoptimized fuzzy search? | 11:13:30 |

https://hydra.nixos.org/search?query=aaaa it seems that just about any search term that isn't very short will run into query timeouts. also, "aaaa" finds results with four as anywhere in the Job name. is the hydra search doing an unoptimized fuzzy search? https://github.com/NixOS/hydra/blob/master/src/lib/Hydra/Controller/Root.pm#L431 | 11:19:11 |
| Valodim | ah, there's actually "aaaa" in those results elsewhere. so it's really just an ILIKE "%query%" that consistently times out | 11:24:38 |
| @grahamc:nixos.org | in this PR I included some potential improvements to the search behavior: https://github.com/NixOS/hydra/pull/853 | 14:45:47 |
| Valodim | queries that aren't left-anchored don't profit from btree indexes. are you currently using a trigram gin, or any other sort of specialized index for this operation? | 17:35:49 |
| Valodim | with a bit of luck, your woes might be gone with just CREATE INDEX expIndexBuildOutputsPathGin ON BuildOutputs USING GIN (path gin_trgm_ops); | 17:38:44 |
| Valodim | alternatively, maybe just don't allow fully fuzzy LIKEs but use a more specialized matching? I imagine searches by path will all look more or less alike, i.e. for a path /nix/store/hash-name-version the user will likely search either by that full string, or hash-name-version, or hash, or name-version | 17:50:55 |
| Valodim | I have next to no perl experience so probably won't have the time to encode that idea into a PR :\ | 17:51:42 |
| Valodim | Has anyone looked more closely into optimizing those queries yet? If not, I could probably do some experiments and see what works. | 17:56:05 |

 Mic92 | grahamc (he/him): what is your personal roadmap for hydra? | 16:58:17 |
| Mic92 | We don't have enough roadmaps in the nix community. | 16:58:35 |
| @grahamc:nixos.org | +1 | 17:00:59 |
| @grahamc:nixos.org | my driving goals:
- Make it easier to work on (tests, docs)
- Make it faster (database, observability)
- Make it more reliable (obvervability, tests, ???)
this is of course hard to pull off in free time, and sometimes I have clients that want to pay me to do various work along these lines
| 17:03:12 |
| @grahamc:nixos.org | I don't know if that is enough to call it a roadmap | 17:05:25 |
| @grahamc:nixos.org | but it is hard to come up with a roadmap when there isn't a way to easily manifest that roadmap | 17:05:52 |

I don't know if that is enough to call it a roadmap Often times roadmaps result being self-fulfilling prophecies 😁 | 17:16:11 |
