now nix-doc-munge will not introduce whitespace changes when it replaces
manpage references with the MD equivalent.
no change to the manpage, changes to the HTML manual are whitespace only.
the conversion procedure is simple:
- find all things that look like options, ie calls to either `mkOption`
or `lib.mkOption` that take an attrset. remember the attrset as the
option
- for all options, find a `description` attribute who's value is not a
call to `mdDoc` or `lib.mdDoc`
- textually convert the entire value of the attribute to MD with a few
simple regexes (the set from mdize-module.sh)
- if the change produced a change in the manual output, discard
- if the change kept the manual unchanged, add some text to the
description to make sure we've actually found an option. if the
manual changes this time, keep the converted description
this procedure converts 80% of nixos options to markdown. around 2000
options remain to be inspected, but most of those fail the "does not
change the manual output check": currently the MD conversion process
does not faithfully convert docbook tags like <code> and <package>, so
any option using such tags will not be converted at all.
`ConditionPathExists` belongs in the [Unit] section, not [Service].
The unit now properly checks if the cert file already
exists before activating so certs will not be overwritten anymore.
using freeform is the new standard way of using modules and should replace
extraConfig.
In particular, this will allow us to place a condition on mails
Fail scripts on pipeline errors and propagate subshell errors.
If an error occurs in a subshell, including while trying to read a
secret file, we want that error to propagate to the main shell
context. That means we have to set the `inherit_errexit` option, which
allows errors from subshells to propagate to the outer shell. Also,
the subshell cannot run as part of another command, such as `export`,
since that will simply ignore the subshell exit status and only
respect `export`s exit status; first assigning the value to a variable
and then exporting it solves issue.
Using `replace-literal` to insert secrets leaks the secrets through
the `replace-literal` process' `/proc/<pid>/cmdline`
file. `replace-secret` solves this by reading the secret straight from
the file instead, which also simplifies the code a bit.
The upstream recommended minimum length for db_key_base is 30 bytes,
which our option descriptions repeated. Recently, however, upstream
has, in many places, moved to using aes-256-gcm, which requires a key
of exactly 32 bytes. To allow for shorter keys, the upstream code pads
the key in some places. However, in many others, it just truncates the
key if it's too long, leaving it too short if it was to begin
with. This adds a patch that fixes this and updates the descriptions
to recommend a key of at least 32 characters.

This should reduce memory fragmentation drastically and is recommended
by both the Puma and the Sidekiq author. It's also the default value
for Ruby deployments on Heroku.
To make it easier to start and stop all GitLab services, introduce
`gitlab.target` which wants all services (meaning they will start with
it) and which all services are part of (meaning they will stop with
it).
Make the config initialization script run in gitlab.service's PreStart
section into two new services, `gitlab-config.service` and
`gitlab-db-config.service`. Other services can then depend on the
config scripts they need instead of unnecessarily depending on
`gitlab.service`. This makes the reason for the configured service
dependencies much clearer and should also reduce the restart time of
the `gitlab` service quite a lot, when triggered manually.
Also, set up stricter service dependencies, using `bindsTo`, to ensure
that if a service fails or is stopped, its dependants are also
stopped. For example, if we're using the `postgresql` service and it's
stopped, `gitlab.service` and `gitlab-sidekiq.service`, which depend on
it to function, should also be stopped.
A function is more appropriate for this use. See
http://mywiki.wooledge.org/BashFAQ/050 for reference.
Also, we don't need to run the service as root: since we essentially
run all commands as `services.postgresql.superUser` anyway, the whole
service can just run as that user instead.
Change the default SMTP port to `25`, to better match the default
address `localhost`. This gets rid of some error outputs in the test,
where it fails to connect to localhost:465.
Also, don't enable postfix by default unless it's actually useful to
us.
This removes all the subdirectories in `config` on start.
From one version of GitLab to the next, the files in the `config`
directory changes. Since we're only overwriting the existing files
with ones from the repo, cruft sometimes gets left behind,
occationally causing issues.
Ideally, all configuration put in the `config` directory is declared
by NixOS options and we could just remove the whole directory on
start, but I'm not sure if that's the case. It would also require a
little bit of additional rework and testing. The subdirectories,
however, should seldom contain user configuration and the ones that
frequently does, `initializers`, is already removed on start.
