Setting up a XMPP chat server is a pretty deep rabbit whole to jump in when you're not familiar with this whole universe. Your experience with this environment will greatly depends on whether or not your server implements the right set of XEPs. To tackle this problem, the XMPP community came with the idea of creating a meta-XEP in charge of listing the desirable XEPs to comply with. This meta-XMP is issued every year under an new XEP number. The 2020 one being XEP-0423[1]. This prosody nixos module refactoring makes complying with XEP-0423 easier. All the necessary extensions are enabled by default. For some extensions (MUC and HTTP_UPLOAD), we need some input from the user and cannot provide a sensible default nixpkgs-wide. For those, we guide the user using a couple of assertions explaining the remaining manual steps to perform. We took advantage of this substential refactoring to refresh the associated nixos test. Changelog: - Update the prosody package to provide the necessary community modules in order to comply with XEP-0423. This is a tradeoff, as depending on their configuration, the user might end up not using them and wasting some disk space. That being said, adding those will allow the XEP-0423 users, which I expect to be the majority of users, to leverage a bit more the binary cache. - Add a muc submodule populated with the prosody muc defaults. - Add a http_upload submodule in charge of setting up a basic http server handling the user uploads. This submodule is in is spinning up an HTTP(s) server in charge of receiving and serving the user's attachments. - Advertise both the MUCs and the http_upload endpoints using mod disco. - Use the slixmpp library in place of the now defunct sleekxmpp for the prosody NixOS test. - Update the nixos test to setup and test the MUC and http upload features. - Add a couple of assertions triggered if the setup is not xep-0423 compliant.

Other Project Repositories
The sources of all official Nix-related projects are in the NixOS organization on GitHub. Here are some of the main ones:
- Nix - the purely functional package manager
- NixOps - the tool to remotely deploy NixOS machines
- Nix RFCs - the formal process for making substantial changes to the community
- NixOS homepage - the NixOS.org website
- hydra - our continuous integration system
- NixOS Artwork - NixOS artwork
Continuous Integration and Distribution
Nixpkgs and NixOS are built and tested by our continuous integration system, Hydra.
- Continuous package builds for unstable/master
- Continuous package builds for the NixOS 20.03 release
- Tests for unstable/master
- Tests for the NixOS 20.03 release
Artifacts successfully built with Hydra are published to cache at https://cache.nixos.org/. When successful build and test criteria are met, the Nixpkgs expressions are distributed via Nix channels.
Contributing
Nixpkgs is among the most active projects on GitHub. While thousands of open issues and pull requests might seem a lot at first, it helps consider it in the context of the scope of the project. Nixpkgs describes how to build over 40,000 pieces of software and implements a Linux distribution. The GitHub Insights page gives a sense of the project activity.
Community contributions are always welcome through GitHub Issues and Pull Requests. When pull requests are made, our tooling automation bot, OfBorg will perform various checks to help ensure expression quality.
The Nixpkgs maintainers are people who have assigned themselves to maintain specific individual packages. We encourage people who care about a package to assign themselves as a maintainer. When a pull request is made against a package, OfBorg will notify the appropriate maintainer(s). The Nixpkgs committers are people who have been given permission to merge.
Most contributions are based on and merged into these branches:
masteris the main branch where all small contributions gostagingis branched from master, changes that have a big impact on Hydra builds go to this branchstaging-nextis branched from staging and only fixes to stabilize and security fixes with a big impact on Hydra builds should be contributed to this branch. This branch is merged into master when deemed of sufficiently high quality

Donations
The infrastructure for NixOS and related projects is maintained by a nonprofit organization, the NixOS Foundation. To ensure the continuity and expansion of the NixOS infrastructure, we are looking for donations to our organization.
