conversions were done using https://github.com/pennae/nix-doc-munge
using (probably) rev f34e145 running
nix-doc-munge nixos/**/*.nix
nix-doc-munge --import nixos/**/*.nix
the tool ensures that only changes that could affect the generated
manual *but don't* are committed, other changes require manual review
and are discarded.
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.
According to https://repology.org/repository/nix_unstable/problems, we have a
lot of packages that have http links that redirect to https as their homepage.
This commit updates all these packages to use the https links as their
homepage.
The following script was used to make these updates:
```
curl https://repology.org/api/v1/repository/nix_unstable/problems \
| jq '.[] | .problem' -r \
| rg 'Homepage link "(.+)" is a permanent redirect to "(.+)" and should be updated' --replace 's@$1@$2@' \
| sort | uniq > script.sed
find -name '*.nix' | xargs -P4 -- sed -f script.sed -i
```
Some things were provided by default, some by systemd unit and some
were just miraculously working. This turns them into explicit
dependencies of the package itself, making everything properly
overrideable.
+ providing glibcLocales fixes elixir compile warnings
+ providing systemd dependency allows rabbit to use systemctl for unit
activation check instead of falling back to sleep. This was seen as
a warning during startup.
- Use socket-activated epmd - that way there won't be any trouble when
more than one erlang system is used within a single host.
- Use new automation-friendly configuration file format
- Use systemd notifications instead of buggy 'rabbitmqctl wait' for
confirming successful server startup.
'wait' bug: https://github.com/rabbitmq/rabbitmq-server/issues/463
- Use 'rabbitmqctl shutdown' instead of 'stop', because it's not
pid-file based
- Use sane systemd unit defaults from RabbitMQ repo:
https://github.com/rabbitmq/rabbitmq-server/blob/master/docs/rabbitmq-server.service.example
- Support for external plugins
1. The chmod 400 with the preset cookie prevented restarts, as
on the second boot it would fail to write to the cookie. Oops.
2. As far as I can tell, sasl logs were disabled because of the
following error:
{error,{cannot_log_to_tty,sasl_report_tty_h,not_installed}}
Not because we actually wanted to disable them. This meant the
management plugin wasn't usable due to a bug set to be fixed in
3.7.0.
Using pkgs.lib on the spine of module evaluation is problematic
because the pkgs argument depends on the result of module
evaluation. To prevent an infinite recursion, pkgs and some of the
modules are evaluated twice, which is inefficient. Using ‘with lib’
prevents this problem.
