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.
3a1e1f0624 adds a poststart script that
checks if ES successfully started by curling the HTTP endpoint. On nodes with a lot of data or slower disks,
this might take longer than the default systemd startup timeout of 90 seconds.
Before this fix, if the listenAddress is set to something else than 127.0.0.1,
the service fails to detect that Elasticsearch has properly started and stop.
Other services that depend on elasticsearch should be started after
it, but since the versions we're packaging have to run as
"Type=simple", they're started as soon as the elasticsearch binary has
been executed, likely winning the race against it.
This makes sure elasticsearch is up and running, responding to a
simple query, before dependents are started.
This adds the following new packages:
+ elasticsearch7
+ elasticsearch7-oss
+ logstash7
+ logstash7-oss
+ kibana7
+ kibana7-oss
+ filebeat7
+ heartbeat7
+ metricbeat7
+ packetbeat7
+ journalbeat7
The default major version of the ELK stack stays at 6. We should
probably set it to 7 in a next commit.
* The ELK stack is upgraded to 6.3.2.
* `elasticsearch6`, `logstash6` and `kibana6` now come with X-Pack which is
a suite of additional features. These are however licensed under the unfree
"Elastic License".
* Fortunately they also provide OSS versions which are now packaged
under: `elasticsearch6-oss`, `logstash6-oss` and `kibana6-oss`.
Note that the naming of the attributes is consistent with upstream.
* The test `nix-build nixos/tests/elk.nix -A ELK-6` will test the OSS
version by default. You can also run the test on the unfree ELK using:
`NIXPKGS_ALLOW_UNFREE=1 nix-build nixos/tests/elk.nix -A ELK-6 --arg enableUnfree true`
