this converts meta.doc into an md pointer, not an xml pointer. since we
no longer need xml for manual chapters we can also remove support for
manual chapters from md-to-db.sh
since pandoc converts smart quotes to docbook quote elements and our
nixos-render-docs does not we lose this distinction in the rendered
output. that's probably not that bad, our stylesheet didn't make use of
this anyway (and pre-23.05 versions of the chapters didn't use quote
elements either).
also updates the nixpkgs manual to clarify that option docs support all
extensions (although it doesn't support headings at all, so heading
anchors don't work by extension).
In an effort to better encode version strings and use descriptive pnames
that do not conflict with top level pkgs, we currently use
wordpress-${type}-${pname} for pname. This is good for the nix store,
but when we synthesize the wordpress derivation in our module, we reuse
this pname for the output directory.
Internally wordpress can handle this fine, since plugins must register
via php, not directory. Unfortunately, many plugins like civicrm and
wpforms-lite are designed to rely upon the name of their install
directory for homing or discovery.
As such, we should follow both the upstream convention and
services.nextcloud.extraApps and use an attribute set for these options.
This allows us to not have to deal with the implementation details of
plugins and themes, which differ from official and third party, but also
give users the option to override the install location. The only issue
is that it breaks the current api.
apparently pandoc has changed behavior over the past releases, so the
files are no longer in sync. occasionally this requires edits
to the markdown source to not remove an anchor that was there
before (albeit wth a very questionable id), or where things were simply
being misrendered due to syntax errors.
we only have three uses at the moment, all of them in code blocks where
they could just as well (or maybe better) be comments. markdown can't do
callouts without another pandoc filter, so we'll turn them into comments
instead.
synapse would've benefited from inline links, but referencing an
external numbered list as plain text (instead of clickable links, like
callout lists had) seems even worse than putting urls into comments as
plain text.
productname, application, acronym, guilabel, and guibutton were so far
not rendered specially and can go away completely.
replaceable does render differently, but since it was only used twice
and in places where the intent should be clear without the extra markup
it can go as well.
makes sure that program listing tags are separated from their contents
by exactly a newline character. this makes the markdown translation
easier to verify (since no new newlines need to be inserted), and
there's no rendering difference anyway.
MD can only do the latter, so change them all over now to keeps diffs reviewable.
this also includes <literal><xref> -> <xref> where options are referenced since
the reference will implicitly add an inner literal tag.
markdown cannot represent those links. remove them all now instead of in
each chapter conversion to keep the diff for each chapter small and more
understandable.
Added the RFC42-style added the posibility to use
`services.dokuwiki.sites.<name>.settings' instead of passing a plain
string to `<name>.extraConfig`. ´<name>.pluginsConfig` now also accepts
structured configuration.
The `snipe-it-setup.service` script exits with an error if the
invalid_barcode.gif already exists at the destination, due to
`set -euo pipefail` at the beginning of the script. This commit
refactors the affected lines so that it no longer causes an error.
Resolves#205791
Upon testing the change itself I realized that it doesn't build properly
because
* the `pname` of a php extension is `php-<name>`, not `<name>`.
* calling the extension `openssl-legacy` resulted in PHP trying to compile
`ext/openssl-legacy` which broke since it doesn't exist:
source root is php-8.1.12
setting SOURCE_DATE_EPOCH to timestamp 1666719000 of file php-8.1.12/win32/wsyslog.c
patching sources
cdToExtensionRootPhase
/nix/store/48mnkga4kh84xyiqwzx8v7iv090i7z66-stdenv-linux/setup: line 1399: cd: ext/openssl-legacy: No such file or directory
I didn't encounter that one before because I was mostly interested in
having a sane behavior for everyone not using this "feature" and the
documentation around this. My findings about the behavior with turning
openssl1.1 on/off are still valid because I tested this on `master` with
manually replacing `openssl` by `openssl_1_1` in `php-packages.nix`.
To work around the issue I had to slightly modify the extension
build-system for PHP:
* The attribute `extensionName` is now relevant to determine the output
paths (e.g. `lib/openssl.so`). This is not a behavioral change for
existing extensions because then `extensionName==name`.
However when specifying `extName` in `php-packages.nix` this value is
overridden and it is made sure that the extension called `extName` NOT
`name` (i.e. `openssl` vs `openssl-legacy`) is built and installed.
The `name` still has to be kept to keep the legacy openssl available
as `php.extensions.openssl-legacy`.
Additionally I implemented a small VM test to check the behavior with
server-side encryption:
* For `stateVersion` below 22.11, OpenSSL 1.1 is used (in `basic.nix`
it's checked that OpenSSL 3 is used). With that the "default"
behavior of the module is checked.
* It is ensured that the PHP interpreter for Nextcloud's php-fpm
actually loads the correct openssl extension.
* It is tested that (encrypted) files remain usable when (temporarily)
installing OpenSSL3 (of course then they're not decryptable, but on a
rollback that should still be possible).
Finally, a few more documentation changes:
* I also mentioned the issue in `nextcloud.xml` to make sure the issue
is at least mentioned in the manual section about Nextcloud. Not too
much detail here, but the relevant option `enableBrokenCiphersForSSE`
is referenced.
* I fixed a few minor wording issues to also give the full context
(we're talking about Nextcloud; we're talking about the PHP extension
**only**; please check if you really need this even though it's
enabled by default).
This is because I felt that sometimes it might be hard to understand
what's going on when e.g. an eval-warning appears without telling where
exactly it comes from.
* s/NextCloud/Nextcloud/g
* `enableBrokenCiphersForSSE` should be enabled by default for any NixOS
installation from before 22.11 to make sure existing installations
don't run into the issue. Not the other way round.
* Update release notes to reflect on that.
* Improve wording of the warning a bit: explain which option to change
to get rid of it.
* Ensure that basic tests w/o `enableBrokenCiphersForSSE` run with
OpenSSL 3.
Not a big deal in most of the cases because wordpress ensures that this
directory exists on its own, but with our twentig customizations that's
actually causing issues.

this makes it easier for one to manually administer freshrss.
for example, i can import OPML from the CLI like:
```
$ nix build .#freshrss
$ freshrss FRESHRSS_DATA_PATH=/var/lib/freshrss ./result/cli/import-for-user.php --user admin --file my-opml.opml
```
whereas previously i would have needed to include
`environment.systemPackages = [ php ];` in my system for that to work.

most of these are hidden because they're either part of a submodule that
doesn't have its type rendered (eg because the submodule type is used in
an either type) or because they are explicitly hidden. some of them are
merely hidden from nix-doc-munge by how their option is put together.
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.
there are sufficiently few variable list around, and they are
sufficiently simple, that it doesn't seem helpful to add another
markdown extension for them. rendering differences are small, except in
the tor module: admonitions inside other blocks cannot be made to work
well with mistune (and likely most other markdown processors), so those
had to be shuffled a bit. we also lose paragraph breaks in the list
items due to how we have to render from markdown to docbook, but once we
remove docbook from the pipeline those paragraph breaks will be restored.
mostly no rendering changes. some lists (like simplelist) don't have an
exact translation to markdown, so we use a comma-separated list of
literals instead.
most of the screen tags used in option docs are actually listings of
some sort. nsd had a notable exception where its screen usage was pretty
much a raw markdown block that made most sense to convert into docbook lists.
#167013 introduced a property conflict with the concurrently-written commit
aea940da63, over property
systemd.services.prosody. Fix this by moving the reload option into the block.
using regular strings works well for docbook because docbook is not as
whitespace-sensitive as markdown. markdown would render all of these as
code blocks when given the chance.
a lot of markdown syntax has already snuck into option docs, many of it
predating the intent to migrate to markdown. we don't convert all of it
here, just that which is accompanied by docbook tags as well. the rest
can be converted by simply adding the mdDoc marker.
this renders the same in the manpage and a little more clearly in the
html manual. in the manpage there continues to be no distinction from
regular text, the html manual gets code-type markup (which was probably
the intention for most of these uses anyway).
Plausible fails on start because clickhouse is not ready,
when clickhouse has low CPU available, eg.
```nix
{systemd.services.clickhouse.serviceConfig.CPUWeight = 20;}
```
Fixed with
```nix
{systemd.services.plausible.after = [ "clickhouse.service" ];}
```
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.
make (almost) all links appear on only a single line, with no
unnecessary whitespace, using double quotes for attributes. this lets us
automatically convert them to markdown easily.
the few remaining links are extremely long link in a gnome module, we'll
come back to those at a later date.
markdown can't represent the difference without another extension and
both the html manual and the manpage render them the same, so keeping the
distinction is not very useful on its own. with the distinction removed
we can automatically convert many options that use <code> tags to markdown.
the manpage remains unchanged, html manual does not render
differently (but class names on code tags do change from "code" to "literal").
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 option `services.jira.sso.applicationPassword` has been replaced by
`applicationPasswordFile` that needs to be readable by the `jira`-user
or group.
The new `crowd.properties` is created on startup in `~jira` and the
secret is injected into it using `replace-secret`.
Transform exit handlers of the form
trap cleanup EXIT [INT] [TERM] [QUIT] [HUP] [ERR]
(where cleanup is idempotent)
to
trap cleanup EXIT
This fixes a common bash antipattern.
Each of the above signals causes the script to exit. For each signal,
bash first handles the signal by running `cleanup` and then runs
`cleanup` again when handling EXIT.
(Exception: `vscode/*` prevents the second run of `cleanup` by removing
the trap in cleanup`).
Simplify the cleanup logic by just trapping exit, which is always run
when the script exits due to any of the above signals.
Note: In case of borgbackup, the exit handler is not idempotent, but just
trapping EXIT guarantees that it's only run once.
Commit 8109d8a set the `StateDirectory=` option of the systemd service
configuration to the value of `cfg.workDir` which is wrong, according
to dasJ [1]. This commit resolves this issue by stripping the
`/var/lib/` prefix from `cfg.workDir`.
[1] https://github.com/NixOS/nixpkgs/pull/172824#issuecomment-1130350412
There is a comment above the invocation of 'nextcloud-occ app:enable', stating
that the script should not fail if any of the apps cannot be enabled, but there
is nothing in place to suppress errors. The app:enable command already
continues installing the remaining apps when one fails to install, and we do not
want to suppress errors in the setup script, so this just removes the comment
about not failing.
* Add an option services.nextcloud.nginx.hstsMaxAge for setting the max-age
directive of the Strict-Transport-Security HTTP header.
* Make the Strict-Transport-Security HTTP header in the Nginx virtualhost block
dependant upon the option services.nextcloud.https instead of
services.nextcloud.nginx.recommendedHttpHeaders, as this header makes no sense
when not using HTTPS. (Closes#169465)
Added Nextcloud 23 and set it as the default Nextcloud version for the
NixOS module. Added PHP 8.1 as an option for phpPackage and default for
Nextcloud ≥ 24.

I recently learned that Nextcloud 23's new profile feature — basically a
way for users to share personal contact details — has a problematic
default setting, profile data is shared with **everyone** by default.
This means that an unauthenticated user can access personal information
by accessing `nextcloud.tld/u/user.name`.
The announcement of v23 states[1]:
> We go a step further and introduce a profile page. Here you can put a
> description of yourself, show links to, for example, social media, what
> department you are in and information on how to contact you. All these
> are of course entirely optional and you can choose what is visible to who!
> The profile and user status are accessible also from our mobile and desktop clients.
It's not mentioned that by default you share personal information[3] with
everyone and personally I think that's somewhat problematic.
To work around that, I decided to add an option for the recently added[2]
and even set it to `false` by default to make an explicit opt-in for
that feature.

With version 17 of Keycloak, the Wildfly based distribution was
deprecated in favor of the one based on Quarkus. The difference in
configuration is massive and to accommodate it, both the package and
module had to be rewritten.
This fixes the following issues with the database provisioning script
included in the services.keycloak module:
- It lacked permission to access the DB password file specified in the
module option 'services.keycloak.database.passwordFile'.
- It prevented Keycloak from starting after the second time if the user
chose MySQL for the database.
If a secret path is a subset of a second secret path, there's a risk
that its secret is substituted for the matching part of the second
path. To prevent this, use the sha256 of the paths as placeholder
string instead.
users.users.*.createHome makes home only owner-readable.
This breaks nginx reading static assets from nextcloud's home,
after a nixos-rebuild that did not restart nextcloud-setup.
Closes#112639
This commit introduces a new option
`services.nextcloud.nginx.recommendedHttpHeaders` that can be used to
optionally disable serving recommended HTTP Response Headers in nginx.
This is especially useful if some headers are already configured
elsewhere to be served in nginx and thus result in duplicate headers.
Resolves#120223
The `extraConfig` parameter only handles text - it doesn't support
arbitrary secrets and, with the way it's processed in the setup
script, it's very easy to accidentally unescape the echoed string and
run shell commands / feed garbage to bash.
To fix this, implement a new option, `config`, which instead takes a
typed attribute set, generates the `.env` file in nix and does
arbitrary secret replacement. This option is then used to provide the
configuration for all other options which change the `.env` file.
When upgrading bookstack, if something in the cache conflicts with the
new installation, the artisan commands might fail. To solve this, make
the cache lifetime bound to the setup service. This also removes the
`cacheDir` option, since the path is now handled automatically by
systemd.
Instead of referencing all library functions through `lib.` and
builtins through `builtins.` at every invocation, inherit them into
the appropriate scope.
Use systemd's LoadCredential mechanism to make the secret files
available to the service.
This gets rid of the privileged part of the ExecPreStart script which
only served to copy these files and assign the correct
permissions. There's been issues with this approach when used in
combination with DynamicUser, where sometimes the user isn't created
before the ExecPreStart script runs, causing the error
install: invalid user ‘keycloak’
This should fix that issue.
Unfortunately, all of the ExecPreStart script had to be moved to
ExecStart, since credentials aren't provided to ExecPreStart. See
https://github.com/systemd/systemd/issues/19604.
This together with extraConfig:
{
"subsystem=undertow"."server=default-server"."http-listener=default"."proxy-address-forwarding" = true;
"subsystem=undertow"."server=default-server"."https-listener=https"."proxy-address-forwarding" = true;
}
Allows to run Keycloak behind a reverse proxy that provides
X-Forwarded-* headers.
Allow update commands in the script to be ordered using `mkOrder`.
If we encounter ordered sub-objects we sort them by priority.
To implement this we now explicitly pass current node in `recurse`,
which also allows us to clean up edge case for top-level node.
Also refactor `recurse` to avoid passing result text argument; we
weren't tail recursive before anyway.
link to search.nixos.org instead of pulling package metadata out of pkgs. this
lets us cache docs of a few more modules and provides easier access to package
info from the HTML manual, but makes the manpage slightly less useful since
package description are no longer rendered.
most modules can be evaluated for their documentation in a very
restricted environment that doesn't include all of nixpkgs. this
evaluation can then be cached and reused for subsequent builds, merging
only documentation that has changed into the cached set. since nixos
ships with a large number of modules of which only a few are used in any
given config this can save evaluation a huge percentage of nixos
options available in any given config.
in tests of this caching, despite having to copy most of nixos/, saves
about 80% of the time needed to build the system manual, or about two
second on the machine used for testing. build time for a full system
config shrank from 9.4s to 7.4s, while turning documentation off
entirely shortened the build to 7.1s.
One use case for Mattermost configuration is doing a "mostly

Remove the reliance on readFile (it's flake incompatible) and use

some options have default that are best described in prose, such as
defaults that depend on the system stateVersion, defaults that are
derivations specific to the surrounding context, or those where the
expression is much longer and harder to understand than a simple text
snippet.
escape interpolations in descriptions where possible, replace them with
sufficiently descriptive text elsewhere. also expand cfg.* paths in
descriptions.
Instead of patching the path to /public in Discourse's sources, make
the nginx configuration refer to the symlink in the discourse
package which points to the real path.
When there is a mismatch between the path nginx serves and the path
Discourse thinks it serves, we can run into issues like files not
being served - at least when sendfile requests from the ruby app are
processed by nginx. The issue I ran into most recently is that backup
downloads don't work.
Since Discourse refers to the public directory relative to the Rails
root in many places, it's much easier to just sync this path to the
nginx configuration than trying to patch all occurrences in the
sources. This should hopefully mean less potential for breakage in
future Discourse releases, too.
Also, add support for updating plugins which keep gem versions in
files at the root of the repo (discourse-prometheus) and replace the
`up-plugin.sh` script with a README file pointing to the plugin
packaging documentation.

The version 20 of Nextcloud will be EOLed by the end of this month[1].
Since the recommended default (that didn't raise an eval-warning) on
21.05 was Nextcloud 21, this shouldn't affect too many people.
In order to ensure that nobody does a (not working) upgrade across
several major-versions of Nextcloud, I replaced the derivation of
`nextcloud20` with a `throw` that provides instructions how to proceed.
The only case that I consider "risky" is a setup upgraded from 21.05 (or
older) with a `system.stateVersion` <21.11 and with
`services.nextcloud.package` not explicitly declared in its config. To
avoid that, I also left the `else-if` for `stateVersion < 21.03` which
now sets `services.nextcloud.package` to `pkgs.nextcloud20` and thus
leads to an eval-error. This condition can be removed
as soon as 21.05 is EOL because then it's safe to assume that only
21.11. is used as stable release where no Nextcloud <=20 exists that can
lead to such an issue.
It can't be removed earlier because then every `system.stateVersion <
21.11` would lead to `nextcloud21` which is a problem if `nextcloud19`
is still used.
[1] https://docs.nextcloud.com/server/20/admin_manual/release_schedule.html
A few minor changes to get #119638 - nextcloud: add option to set
datadir and extensions - ready:
* `cfg.datadir` now gets `cfg.home` as default to make the type
non-nullable.
* Enhanced the `basic` test to check the behavior with a custom datadir
that's not `/var/lib/nextcloud`.
* Fix hashes for apps in option example.
* Simplify if/else for `appstoreenable` in override config.
* Simplify a few `mapAttrsToList`-expressions in
`nextcloud-setup.service`.
Note the appstoreEnable which will prevent nextcloud form updating
nix-managed apps. This is needed because nextcloud will store an other
version of the app in /var/lib/nextcloud/store-apps and it will
no longer be manageable.
The `$(</path/to/file)`-expansion appears verbatim in the cmdline of
`nextcloud-occ` which means that an unprivileged user could find
sensitive values (i.e. admin password & database password) by monitoring
`/proc/<pid>/cmdline`.
Now, these values don't appear in a command line anymore, but will be
passed as environment variables to `nextcloud-occ`.
* Linkify documentation about objectstore-feature rather than only
mentioning it.
* Use `<literal>` where it makes sense.
* Remove unnecessary `Whether to load` from `enableImagemagick` because
`mkEnableOption` already prepends `Whether to enable` to the given
description.
Previously, the `nix_read_pwd` function was only used for reading the
`dbpassFile`, however it has since been refactored to handle reading
other secret files too. This fixes the message of the exception that is
thrown in the case that the file is not present so that it no longer
refers specifically to the `dbpass` file.
Removes the submodule in favour of using an attrset.
Also:
- Makes better use of nix's laziness in config expansion.
- Makes use of `boolToString` where applicable.
We should discourage users from adding secrets in a way that allows for
them to end up in the globally readable `/nix/store`. Users should use
the `objectstore.s3.secretFile` option instead.
This allows to declaratively configure an S3 class object storage as the
primary storage for the nextcloud service. Previously, this could only
be achieved by manually editing the `config.php`.
I've started testing this today with my own digitalocean nextcloud
instance, which now points to my digitalocean S3-compatible "Space" and
all appears to be working smoothly.
My motivation for this change is my recent discovery of how much cheaper
some S3-compatible object storage options are compared to digitalocean's
"Volume" options.
Implementation follows the "Simple Storage Service" instructions here:
https://docs.nextcloud.com/server/latest/admin_manual/configuration_files/primary_storage.html
I have neglected to implement a submodule for the OpenStack Swift
object storage as I don't personally have a use case for it or a method
to test it, however the new `nextcloud.objectstore.s3` submodule should
act as a useful guide for anyone who does wish to implement it.
The MariaDB version 10.6 doesn't seem supported with current Nextcloud
versions and the test fails with the following error[1]:
nextcloud # [ 14.950034] nextcloud-setup-start[1001]: Error while trying to initialise the database: An exception occurred while executing a query: SQLSTATE[HY000]: General error: 4047 InnoDB refuses to write tables with ROW_FORMAT=COMPRESSED or KEY_BLOCK_SIZE.
According to a support-thread in upstream's Discourse[2] this is because
of a missing support so far.
Considering that we haven't received any bugreports so far - even though
the issue already exists on master - and the workaround[3] appears to
work fine, an evaluation warning for administrators should be
sufficient.

When restoring a backup, discourse decompresses the backup archive in
the /share/discourse/tmp dir. Before this change, it is linked to /run
which is typically backed by memory, so the backup will fail to
restore if you do not have enough memory on your system to contain the
backup. This has already happened to me on two small forums.
This moves tmp to the StateDirectory /var/lib/discourse/tmp which is
typically backed by disk.
