[bug#42899] [PATCH 00/10] Dovecot improvements. Add support for pigeonhole.

[Alexey Abramov]

Hi Guix,

I did some work on dovecot, and now can run it with sieve/managesieve
support. I followed the same aproach NixOS guys did. I patched moduledir in
the source code (/etc/dovecot/modules), and provide it as a symlink to current
system profiles lib/dovecot.

I also added fts plugin support for dovecot, added few more options for sieve
protocol configuration.

Alexey Abramov (10):
  gnu: dovecot: Add lucene library to support fts indexing.
  gnu: dovecot: Patch and provide a static path for module directory.
  services: dovecot: Use modules via symlink to system profile.
  gnu: dovecot-pigeonhole: Add new variable.
  services: dovecot: Serialize global settings first.
  services: dovecot: Only serialize settings with non-empty values.
  services: dovecot: Add 'mail-attribute-dict' configuration option.
  services: dovecot: Add 'imap-metadata?' protocol configuration option.
  services: dovecot: Add 'managesieve-notify-capability' configuration.
  services: dovecot: Add 'managesieve-sieve-capability' option.

+Subject: [PATCH] Use static path for moduledir.
+
+Patch was taken from NixOS repo. Make dovecot look for plugins in
+/etc/dovecot/modules so we can symlink plugins from several packages

[Alexey Abramov]

* gnu/services/mail.scm (serialize-space-separated-string-list): Protocols
might have custom settings, which are not supported by other protocols. To
prevent dovecot/services from crashing, serialize settings that hold non-empty
values only.

[bug#42899] [PATCH v2 02/10] gnu: dovecot: Patch and provide a static path for module directory.

[Efraim Flashner]

[-- Attachment #1: Type: text/plain, Size: 8731 bytes --]

How are all the XXX_MODULE_DIR variables set? Would it be possible to
just set MODULE_DIR to /etc/dovecot/modules and leave the others as-is?
They seem to just use a file/folder under MODULE_DIR.

They set during compilation time. If I pass it as a configuration option, dovecot will try to install libraries there which won't work.

For example:

This was enough to jog my memory that we have a couple of packages (with
services) that have configure flags for one directory and install to
%outputs as expected. I came up with the attached patch to make that
happen.

Make sure you run 'guix lint' on the package, some of the lines are too
long.

Is there a difference between dovecot-2.3-pigeonhole-0.5.11.tar.gz and
dovecot-2.3.11-pigeonhole-0.5.11.tar.gz?

it doesn't looke like automake, autoconf, libtool or gettext are
necessary here. Also, 'guix gc --references' show a reference to
dovecot, so that should go in inputs.

If you change the lambda to (lambda* (#:key outputs #:allow-other-keys)
then you can change the let to (let ((out (assoc-ref outputs "out")))
and it fits better with the code formatting in the rest of Guix.

Some of these lines are too long. We try to wrap them at 80, and the
linter complains once it hits 90. If you start a new line after 'out'
then it should flow nicely.

I would shorten this to 'Mail filtering in Dovecot using the Sieve
language'

It looked to me like it was just lgpl2.1

[bug#42899] [PATCH 00/10] Dovecot improvements. Add support for pigeonhole.

[Efraim Flashner]

[-- Attachment #1: Type: text/plain, Size: 473 bytes --]

There's some changes to dovecot and the dovecot service here. I don't
use the dovecot service so I don't really feel comfortable reviewing it
in depth.

I believe some of the others who use the dovecot service will be coming
by to test out those bits.

Thank you very much! I have just tested it, and as you might probably know everything works as expected. I will push your updated patch as soon as guys review the services part.

Hm, I didn't even know that you can download the latter one. I used the URL provided from the [1]

Anyways, I have downloaded both of them and did a check. Most of the differences relate to Makefile.in, however I also found that the ChangeLog file from "2.3" is newer then "2.3.11". The latter miss one change. Please see the diff I have attached. So I guess we should use dovecot-2.3-pigeonhole-0.5.11.tar.gz.

It is indeed not required. I  removed native-imports completely and everithing builds OK. I also moved dovecot to inputs, checked 'guix gc --references', but it turned out that it shows dovecot anyways.

As I understood, it means that if someone have dovecot and dovecot-pigeonhole installed, and the decide to remove pigeonhole, dovecot will be GCed. Please correct me if am wrong.

Done. Yeah, I saw this, but decided that separating the last argument is not that pretty.

Done. I am fine with that. As a non native speaker I usually prefer not to touch these kind of things, until I am really sure it can be improved. =)

Sorry, I am not following. I removed the comment I left indeed. Do you mean I should remove

(license:non-copyleft "file://COPYING")

the part completely? The blob contains both COPYING and COPYING.LGPL so I just copied them both.

That was quick, thanks! Glad to hear everything is OK. Well, this time I sent a cover letter to a guix-devel only for some reason. =( I described the changes in general.

V4 doesn't have anything new. I just rebase v3 and provide v4 to let you guys apply/merge/work with them easier. Well, at least, I think it would be easier.

[bug#42899] [PATCH v5 0/6] Dovecot improvements

I have updated the series. Dovecot modules are provided via computed set of
modules, which is available via /usr/lib/dovecot symlink. All other linux
distribution uses the very same location, so I followed the same rule.

  services: dovecot: Provide plugins through a /gnu/store directory.
  services: dovecot: Add 'mail-attribute-dict' configuration option.
  services: dovecot: Add 'imap-metadata?' protocol configuration option.

  services: dovecot: Add 'managesieve-sieve-capability' option.

[bug#42899] [PATCH v5 2/6] services: dovecot: Provide plugins through a /gnu/store directory.

[Alexey Abramov]

* gnu/services/mail.scm (package-list?, serialize-package-list):
* gnu/services/mail.scm (dovecot-configuration)[extensions]: New field. The field
lets you provide a list of dovecot plugins that need to be available during
the runtime. A union of the set of modules will be created on the activation time.
* gnu/services/mail.scm (opaque-dovecot-configuration)[extensions]: Likewise.
* gnu/services/mail.scm (%dovecot-moduledir): New function.
* gnu/services/mail.scm (%dovecot-activation): Add step to compute a set of
modules, and provide them over the shared link at /usr/lib/dovecot.
* doc/guix.texi (Mail Services)[extension]: Add documentation.

[bug#42899] [PATCH 00/10] Dovecot improvements. Add support for pigeonhole.

[Thomas Ieong]

Hey,

I'm slowly getting back into contributing to guix again, gonna apply these
patchs and see if we can still make it  work.

[bug#42899] [PATCH v6 0/3] services: dovecot: Add pigeonhole support

[Alexey Abramov via Guix-patches via]

Hi everyone,

It is been a while.. I add some changes to the previous series.

- I changed the location of modules to /usr/lib/dovecot instead of
  /etc/dovecot. Don't know why). /usr/lib/dovecot seems natural to me.
- I renamed `%dovecot-moduledir' to make-dovecot-moduledir, and now use
  union-build to create the union of modules.
- %dovecot-activation uses switch-symlinks now.
- I changed the tests a little bit, so that email will go through a simple
  sieve script.

Alexey Abramov (3):
  gnu: dovecot: Set moduledir to global directory.
  services: dovecot: Provide plugins through a /gnu/store directory.
  tests: dovecot: Add sieve.

[bug#42899] [PATCH v6 3/3] tests: dovecot: Add sieve.

[Alexey Abramov via Guix-patches via]

* gnu/tests/mail.scm (%dovecot-os): Add dovecot-pigeonhole and simple
imapsieve configuration.
* gnu/tests/mail.scm (run-dovecot-test): Define simple sieve
script. Add SELECT TESTBOX step to let dovecot properly do mailbox
synchronization.

[bug#42899] [PATCH v6 0/3] services: dovecot: Add pigeonhole support

[Simon Streit]

Hello Alexey,

Alexey Abramov via Guix-patches via <guix-patches@gnu.org> writes:

> - I changed the location of modules to /usr/lib/dovecot instead of

I applied the patches and got it working too. 


Kind regards
