Allow reloading the webserver, which is useful when e.g there are new
certificates available that we want lighttpd to use, but don't want to
completely shut down the server.
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.
The output of ./configure shows all modules/plugins, both enabled and
disabled. With this info we can finally build the _complete_ list of
modules. We were missing these:
mod_authn_gssapi
mod_authn_ldap
mod_geoip
(I hit this as I was building lighttpd with ldap support and the NixOS
module said ldap was unsupported, due to these missing entries in
allKnownModules.)
enableUpstreamMimeTypes controls whether to include the list of mime
types bundled with lighttpd (upstream). This option is enabled by
default and gives a much more complete mime type list than we currently
have. If you disable this, no mime types will be added by NixOS and you
will have to add your own mime types in services.lighttpd.extraConfig.
* mod_dirlisting is auto-loaded by lighttpd and should not be explicitly
loaded in the configuration file.
* The rest comes from looking at "ls -1 $lighttpd/lib/*.so" when
lighttpd is built with "enableMagnet" and "enableMysql".
This option makes the coupling between lighttpd and its sub-services
more "loose".
While the option is a list, its purpose is to provide a "set" of needed
modules to load for lighttpd to function correctly with its config. The
NixOS lighttpd module ensures that lighttpd modules are loaded no more
than once (because lighttpd dislikes that), and in the correct order.
Also add an assertion that all modules listed in .enableModules are
valid.
Setting "services.lighttpd.gitweb.enable" to true doesn't enable the
required lighttpd modules to actually make it work. The problem is that
"or" and "||" don't mean the same thing: "or" falls back to the second
operand if the first is not defined, whereas "||" is the normal logical
operator. When cfg.cgit.enable is defined, as false, the expressions
don't have the desired effect.
[Bjørn: modify commit message]
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.
