matrix-synapse: bump to nixos 21.05, new structure 
This patches an import path for our new structure, and adjusts the build
inputs for our hacked version of matrix-synapse with a newer version of
twisted (for tls 1.3 support), which is apparently still necessary even
in nixos 21.05.

Seems to build fine (have not waited for all tests in the matrix packag;
these take ages)

hacc nixfiles

welcome to hacc nixfiles (haccfiles). this is the code describing our nix-based infrastructure.

structure

  • default.nix: Entrypoint to the config
  • common/: configuration common to all hosts
  • desktop/: desktop-relevant communication
  • modules/: home-grown modules for hacc-specific services
  • nix/: sources files, managed with niv
  • pkgs/: packages we built and don't want to upstream

working with the haccfiles

deploy:

nix build -f . deploy.$hostname && ./result switch

$hostname can be replaced with any hostname or group

committing to haccfiles

  • Golden Rule: DO NOT COMMIT TO MAIN
    • exceptions apply, if you are not sure where to commit, don't commit to main
  • split up commits, every commit is one atomic change
    • e.g. no big "did some changes" but instead "updated service x", "updated service y", "update service z"
  • follow the commit format: "$prefix$place: $change"
    • prefix: one of fixup, nothing
    • place: one of "modules/$module", "$hostname/service", "common/($place)", "pkgs/$pkgs" or "sources"
    • change: describe your change, don't go over the character limit where git starts hiding/wrapping
  • Exception: autogenerated messages (merge commits, reverts, etc)
