Java 17 goes EOL in September 2026 and Jenkins already supports Java 21.
So bump the Java version to 21.

After final improvements to the official formatter implementation,
this commit now performs the first treewide reformat of Nix files using it.
This is part of the implementation of RFC 166.
Only "inactive" files are reformatted, meaning only files that
aren't being touched by any PR with activity in the past 2 months.
This is to avoid conflicts for PRs that might soon be merged.
Later we can do a full treewide reformat to get the rest,
which should not cause as many conflicts.
A CI check has already been running for some time to ensure that new and
already-formatted files are formatted, so the files being reformatted here
should also stay formatted.
This commit was automatically created and can be verified using
nix-build a08b3a4d19.tar.gz \
--argstr baseRev b32a094368
result/bin/apply-formatting $NIXPKGS_PATH
these changes were generated with nixq 0.0.2, by running
nixq ">> lib.mdDoc[remove] Argument[keep]" --batchmode nixos/**.nix
nixq ">> mdDoc[remove] Argument[keep]" --batchmode nixos/**.nix
nixq ">> Inherit >> mdDoc[remove]" --batchmode nixos/**.nix
two mentions of the mdDoc function remain in nixos/, both of which
are inside of comments.
Since lib.mdDoc is already defined as just id, this commit is a no-op as
far as Nix (and the built manual) is concerned.
This will cause systemd to chown /var/lib/jenkins to the user that
the jenkins systemd service runs as, fixing permission issues when
mounting /var/lib/jenkins from another data volume.
It uses the same logic that garage is using, too, checking for the
prefix.
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.
Pass the -L flag to curl to make it follow redirects. This fixes an
issue I found when setting up reverse proxy for Jenkins. Without this
fix, the returned HTTP code was stuck at 302, making postStart fail the
service (it expects 200 or 403).
As pointed out by @danbst, the tomcat NixOS module expects packages
listed in services.tomcat.webapps to either be direct .war file paths or
have .war files inside a "webapps" directory.
Commit 4075c10a59
("jenkins: move .war file from $out to $out/lib/jenkins.war") broke
jenkins + tomcat. Fix it by moving jenkins.war to $out/webapps/.
Fixes#14137, also known as:
$ nix-shell -p jenkins
bash: source: /nix/store/ln1yw6c2v8bb2cjqfr1z5aqcssw054wa-jenkins-2.3:
cannot execute binary file
[nix-shell exited with error]
The problem is that jenkins.war is not installed inside the directory
$out, but rather _as the file_ $out. Fix it by moving the file to
$out/lib/jenkins.war.
While at it, move buildCommand so that the "meta" section is at the end
of the expression (standard style), and quote shell variables.
* Perform HTTP HEAD request instead of full GET (lighter weight)
* Don't log output of curl to the journal (it's noise/debug)
* Use explicit http:// URL scheme
* Reduce poll interval from 10s to 2s (respond to state changes
quicker). Probably not relevant on boot (lots of services compete for
the CPU), but online service restarts/reloads should be quicker.
* Pass --fail to curl (should be more robust against false positives)
* Use 4 space indent for shell code.
The current postStart code holds Jenkins off the "started" state until
Jenkins becomes idle. But it should be enough to wait until Jenkins
start handling HTTP requests to consider it "started".
More reasons why the current approach is bad and we should remove it,
from @coreyoconnor in
https://github.com/NixOS/nixpkgs/issues/14991#issuecomment-216572571:
1. Repeatedly curling for a specific human-readable string to
determine "Active" is fragile. For instance, what happens when jenkins
is localized?
2. The time jenkins takes to initializes is variable. This (at least
used to) depend on the number of jobs and any plugin upgrades requested.
3. Jenkins can be requested to restart from the UI. Which will not
affect the status of the service. This means that the service being
"active" does not imply jenkins is initialized. Downstream services
cannot assume jenkins is initialized if the service is active. Might
as well accept that and remove the initialized test from service
startup.
Fixes#14991.
- add missing types in module definitions
- add missing 'defaultText' in module definitions
- wrap example with 'literalExample' where necessary in module definitions
I think the name 'listenAddress' is more descriptive. Other NixOS
modules that define 'host' either use it as listen address or as address
a client connects to. listenAddress is unambiguous.
The addition of 'host' was added earlier today[1], so not bothering with
./nixos/modules/rename.nix.
[1]: 44ea184997 ("jenkins ci enhancement: add port and prefix option")
As named these options enable to specify a bind host and url prefix
to be used by jenkins. Adding these options in the config rather than
using extra arguments allows us to re-use those information in other
services using jenkins such as jenkins-job-builder or a reverse proxy.
The most complex problems were from dealing with switches reverted in
the meantime (gcc5, gmp6, ncurses6).
It's likely that darwin is (still) broken nontrivially.
Jenkins gets (by default) an additional environment of
{ NIX_REMOTE = "daemon"; }
This has the following problems:
1. NIX_REMOTE disappears when users specify additional environment
variables, because defaults have low merge priority.
2. nix cannot be used without additional NIX_PATH envvar, which is
currently missing.
3. If you try to use HTTPS, you'll see that jenkins lacks
SSL_CERT_FILE envvar, causing it to fail.
This commit adds config.environment.sessionVariables and NIX_REMOTE to
the set of variables that are always there for jenkins, making nix and
HTTPS work out of the box.
services.jenkins.environment is now empty by default.
