 liberodark | I allow myself a question if you want.
- ofborg is a rebot that helps to verify commits?
- nixos-community builder helps to build on the fly?
- hydra allows to check a specific state when a release is released?
| 17:24:21 |
| liberodark | I will give you access to a pioneer. | 17:25:13 |
 emily | Hydra builds everything users use, on both the stable and unstable branches | 17:25:18 |
| emily | the community builders are used by contributors to test builds | 17:25:29 |
| liberodark | * I will give you access to a pioneer. So that you can test it on your side. | 17:25:36 |
| emily | (while reviewing code or developing it themselves) | 17:25:38 |
| emily | ofborg temporarily doesn't exist, but usually provides automated builds across all platforms for pull requests before they're merged | 17:25:56 |

| emily | community builders and ofborg have some overlap in use case, Hydra is the most critical thing | 17:26:09 |
| emily | (IIRC the AArch64 community builder was the same machine as the ofborg aarch64-linux builder? but I could be wrong) | 17:26:29 |
 hexa | Appreciated. | 17:26:40 |
| emily | notably ofborg and the community builders are "untrusted", many people can trigger builds on them and they are not considered secure | 17:26:57 |
| emily | Hydra is critical infrastructure, so few people have access to it and it does not trust builds from ofborg or the community builders at all | 17:27:19 |
| emily | Hydra only builds what is actually merged into branches, or things that people with sufficient Hydra permissions set up to be built (e.g. for wide-scale testing) | 17:27:43 |
| liberodark | I understand better, it's clearer and it answers my questions, thank you for your clarifications. emily | 17:28:12 |
 Grimmauld (moving to @grimmauld:grapevine.grimmauld.de) | I understand the community builder is there for community projects and build jobs too big to be feasible on local systems. What exactly are the typical requirements to get access? There have been a couple build jobs i ran so far that took a couple hours each on normal hardware, so far i decided to just build via github actions. But that can only go so far. And the documentation i could find all basically said "open a PR and see what happens", but that feels very spongy.
(For the record, i have other IRL obligations currently, so not relevant until maybe august, but figured i'd ask if the topic were community builders rn) | 21:42:56 |
 Gaétan Lepage | Well, according to me, you will be granted access if you show that you would use it to contribute to ...well, nix (community) projects.
Apart from this, I don't think like that there is hard requirements. | 21:45:14 |
| Gaétan Lepage | AFAIK, It's not really supposed to be used for personal stuff. | 21:45:36 |
| Grimmauld (moving to @grimmauld:grapevine.grimmauld.de) | specifically, i was compiling different linux kernels with different patches for various apparmor features. Those patches are a part of only ubuntu currently, but bringing them to nix would kinda require a builder for it to be any fun developing | 22:09:20 |
| emily | that seems plenty in-scope | 22:10:12 |
| emily | I think any builds you need to do in the course of contributing to Nixpkgs are fine (within the constraints of not hogging all the resources forever of course, but it's often pretty quiet on the boxes) | 22:10:42 |
| Grimmauld (moving to @grimmauld:grapevine.grimmauld.de) | alright thanks, thats reassuring. I will give a shout once i am there. Currently working on my bachelors thesis and systemd hardening while i wait for apparmor upstream to make some progress, so it'll be a bit, but do expect that request eventually | 22:13:12 |
 zowoq | x86 build box costs ~€50. | 23:42:16 |
| emily | ah, server auction? makes sense | 23:47:32 |
| zowoq | We're basically on budget now at €640. | 23:51:18 |
| Gaétan Lepage | You mean that we have right enough to handle our current monthly budget or that we have enough to get an ARM builder ? | 23:52:01 |
| zowoq | Sorry, the former. | 23:56:20 |

| Gaétan Lepage | Ok I see | 00:13:18 |
| Gaétan Lepage | What is your opinion on the feasibility of adding third-party systems to nix-community/infra ? | 00:13:58 |
| Gaétan Lepage | For instance, if some people like liberodark want to "donate" their system to nix-community so that they can be used as builders while still physically keeping the hardware. Would this be feasible ? | 00:15:01 |
