To correctly render HTML reports we make sure to return the following MIME
types instead of "text/plain"
- *.css: "text/css"
- *.js: "application/javascript"
Fixes: #1267
Nowadays `Builds` doesn't reference `Project` directly anymore. This
means that simply resolving both `jobset` and `project` with a single
JOIN from `Builds` doesn't work anymore. Instead we need to resolve the
relation to `jobset` first and then the relation to `project`.
For similar fixes see e.g. c7c4759600.
There's currently no automatic recovery for disconnected databases in
the evaluator. This means if the database is ever temporarily
unavailable, hydra-evaluator will sit and spin with no work
accomplished.
If this condition is caught, the daemon will exit and systemd will be
responsible for resuming the service.
We were using protocol version 6 but requesting version 4. The only
reason that this worked was because of a broken version check in
'nix-store --serve'. That was fixed in
c2d7456926,
which had the side-effect of breaking hydra-queue-runner.

NOTE: I'm well-aware that we have to be careful with this to avoid new
regressions on hydra.nixos.org, so this should only be merged after
extensive testing from more people.
Motivation: I updated Nix in my deployment to 2.9.1 and decided to also
update Hydra in one go (and compile it against the newer Nix). Given
that this also updates the C++ code in `hydra-{queue-runner,eval-jobs}`
this patch might become useful in the future though.
The newest version of git refuses to work on repositories not owned by
the current user. This leads to issues with the /api/scmdiff endpoint:

I used the same solution that was used in NixOS/nix#6440.
Fixes#1214
I started to wonder quite recently why Hydra doesn't send email
notifications anymore to me. I saw the following issue in the log of
`hydra-notify.service`:
May 22 11:57:29 hydra 9bik0bxyxbrklhx6lqwifd6af8kj84va-hydra-notify[1887289]: fatal: unsafe repository ('/var/lib/hydra/scm/git/3e70c16c266ef70dc4198705a688acccf71e932878f178277c9ac47d133cc663' is owned by someone else)

This is also a problem because of Git's fix for CVE-2022-24765[1], so I
applied the same fix as for Nix[2], by using `--git-dir` which skips the
code-path for the ownership-check[3].
