this is preliminary work for migrating mattermost from mysql to
postgresql.
This tool is specific to mattermost, but at least it's easy enough to
build. I'm not sure if it makes sense to upstream, but I guess we can
keep it around here.
this bundles the current package recipe of forgejo in nixpkgs-unstable.
Implies updating forgejo, since nixpkgs-stable is still on 1.20.6 (v6 in
the new version scheme).
This'll mean we have to manually update it same as with mattermost, and
can potentially also help with upstream changes. If we get tired of
that, we can always decide to just use the nixpkgs-unstable version
directly.
Since Lix is now in nixpkgs-unstable-small, I think it's a good time to
use it. This does mean that we now pull in our nix implementation from
an unstable channel, but overall I'm more confident in the Lix team's
ability to not break things than I am in the Nix team's ability to
backport (& then actually release) security updates.
(once Lix is on a stable channel, we can switch back to using it from there)
this copies the current mattermost package definition from upstream
nixpkgs into our repo as-is (that definition itself being a modified
version of our definition that I upstreamed recently).
Since apparently no one else is maintaining the nixpkgs package and I am
apparently maintaining a mattermost package mostly on my own anyways,
this should make upstreaming future changes easier.
mostly just replacing strings to avoid confusion later on. Since our
containers are now ephemeral, renaming them is basically a non-issue
(though the files under /persist/containers & the uffd client name had
to be changed manually)
This jumps Mattermost ESR Versions (see [1] for their release cycle). The
new version makes use of Go's workspace feature, which unfortunately the
buildGoModule function does not (yet?) support [2], and unfortunately this
breaks the previous build process for mattermost.
Further, the new release also makes use of private modules only included
in the (non-free) enterprise version of mattermost which makes it impossible
to build in the usual way even outside of nixpkgs's build abstractions [3].
Both issues can be solved by using Go 1.22, which has added support for
vendoring when using workspaces, and instructing it to ignore errors with
the -e flag. This requires overriding the go-modules derivation's buildPhase.
Finally, this now also build the commands/mmctl subpackage, which contains
a cli utility to administrate mattermost. This currently has its own nixpkgs
package for no reason i can see at all (it also has a version mismatch
between nixpkgs's mattermost and nixpkgs's mmctl).

we decided to:
- get rid of unused packages
- simpify the directory layout since we only have one host anyways
- move our docs (such as they are) in-tree
move some options (the nopersist & container profiles + allowUnfree
packages) into the evalConfig used for containers, so we don't have to
repeat ourselves as much.
also removed some no-longer-needed specialArgs.
also made thelounge work with nopersist, which for some reason it didn't
use before.
This reverts commit 90f4971e88d22da6b2a213bbeb1790f456024b36, and resets
the uffd version to the one we are already using, in hopes of making the
update slightly less painfull (haha).
in theory this might be ready to deploy. Potential hazards & things to
know when actually doing so:
1. the mysql version used by mattermost was updated (the old uses an
openssl which is marked insecure). Might have to migrate a database
2. lots of settings now use RFC 42-style settings, which might contain
new typos
3. this updates uffd (& changes the patches we apply). Since version
dependencies of uffd are basically "whatever debian has" we have
never bothered to match them, but afaik have also never updated uffd
since the initial deploy some years ago. No guarantee it still
works.
4. tracktrain depends on haskellPackages.conferer-warp, which is
currently marked broken. There is no reason for this (it builds
fine). Until fixed upstream, build with NIXPKGS_ALLOW_BROKEN=1.
cf. https://github.com/NixOS/nixpkgs/pull/234784; waiting for a
merge of haskell-updates into 23.05
apparently the 7.1.x series is now old enough that even though it
does still get security fixes, the mattermost team no longer mentions
this on their blog, so we missed out on a couple. fun!
this replaces niv with nix flakes, attempting to preserve the old
structure as much as possible. Notable caveats:
- I'm not sure if flake inputs expose version information anywhere, so
the version in pkgs/mattermost/default.nix is now hardcoded.
Confusingly, this appears to trigger a rebuild. Maybe I've missed something.
- a lot of the old-style host.nix & deploy.nix machinery in nix-hexchen
does not work with flakes, and their newer replacements are not exposed
by upstream; I've put basic imitations of the relevant parts in this repo
- (in particular, directories in hosts/ won't become deployable configs
automatically)
- parts of the code are now probably more complicated than they'd have to be
- old variables names were preserved; confusingly, this means the flake
inputs are still called "sources"
