The upstream default for the thumbnail font is set to "Liberation Serif
Regular" located at /usr/share/fonts which is inaccessible under nix.
(2a2bf3bf55/src/paperless/settings.py (L894))
Paperless throws an error when parsing plaintext files without a valid
font. This change sets a nix default using the liberation_ttf package.
The homebrewed snippet didn't escape vars properly which is an issue because
PAPERLESS_OCR_USER_ARGS requires a JSON string. This also meant a discrepancy
between the services' env vars and paperless-manage's.
Just use the correctly functioning library function for this instead.
According to
https://github.com/NixOS/nixpkgs/issues/147599#issuecomment-1272286679
the bug that prevented this UMask directive from working has been fixed
in systemd, so it should be safe to use now.
This stops paperless-ngx from making everything world-readable on disk,
but it does not change permissions of any files previously created.
Since version 1.10.0 paperless-ngx depends on the NLTK library which is
used to pre-process data for machine learning. NLTK needs certain
data for stemming, stopword removal etc. This data has to be downloaded
first. This commit introduces a new systemd service that does the
downloading.
This causes a reindex of all documents to allow for comments made before
1.12.x to be searchable.
Also change the format of the version file to just include the version,
not the whole store path.
This simplifies version comparisons and causes migrations to run only
when the version has changed.

The nixOS test failed sporadically with a timeout.
This is due to a race condition in the startup of
the scheduler vs the task-queue.
The scheduler runs the migration scripts in "pre-start" and
celery isn't available, yet. The celery worker (paperless-task-queue)
was already started by systemd but was unable to connect
(as the migration scripts from "pre-start" still ran).
This fix adds the necessary "after" condition in the systemd
worker unit and adds a test to "paperless"

`unpaper` requires syscall 238 (`set_mempolicy`).
Add this by un-blocking the systemd syscall filter set `@resources`
which is safe in the context of paperless.
This attribute set isn't passed through the NixOS config resolution
mechanism, which means that we can't use lib.mkDefault here.
Instead, just put it before any user overrides so that if the user
specifies this environment variable it'll just override it anyway.
`paperless-ngx.pythonPath` was incomplete due to the missing paperless-ngx
source, so it had to be amended in the service.
Instead of amending it, define it entirely in the service.
This allows an override of `paperless-ngx.propagatedBuildInputs` to be reflected
in the service's PYTHONPATH.
Handing CAP_NET_BIND_SERVICE to the `paperless-web.service` only makes
sense when it actually wants to bind to a port < 1024. Don't hand it out
if that is not the case.
Finding out how to connect paperless to a PostgreSQL database via unix
sockets and peer authentication took me a few minutes, so leaving a hint
in the extraConfig example seems like a good idea to me.
Also remove unnecessary use of literalExpression for attribute set, it
is only required for complex values like functions or values that depend
on other values or packages.
After uploading a document through the webinterface I started seeing
it killed through the SYSBUS signal. Inspecting the call trace led me to
liblapack's memory allocator, that uses the mbind syscall on Linux.
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 paperless project has moved on to paperless-ng and the original
paperless package in Nixpkgs has stopped working recently (due to
version incompatibility with the providede Django package).
Instead of investing more time into the old module we should migrate all
users to the new module instead.
