Bug 562796 – net-mail/dovecot should use subslots

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Luca Santarelli 2015-10-11 08:47:49 UTC]

Please forgive my un-technicality on the issue.

Dovecot is strict about plugin compatibility: every time it starts, it checks if requested plugins have the same "build" signature as the running instance of dovecot, refusing to work properly in case of a mismatch.

This translates in: everytime there's an update to dovecot in portage and I emerge it, it breaks because I forget to force-reinstall the external plugins I use (mail-filter/dovecot_antispam).

In my un-technicality I've seen that there are packages which get force-reinstalled when other packages get updated. I request to extend this  behaviour to dovecot plugins.

Reproducible: Always

Steps to Reproduce:
1. emerge net-mail/dovecot (when there's an update)
2. /etc/init.d/dovecot restart
3. (try to connect to it)
Actual Results:  
Dovecot refuses the connection, complaining in its logs that external plugins have a version mismatch (Sorry, I don't have the log available)

Expected Results:  
1. emerge should reinstall installed plugins after compiling dovecot

I don't see why not?

dovecot_antispam isn't in tree (anymore?) but I'm happy to add this if eras has no objections. Is there anything which needs to subscribe to the subslot in ::gentoo, or should we just provide it/

[Comment 3 Eray Aslan 2021-09-10 14:15:25 UTC]

no objections and no subslot consumer in ::gentoo afaik but

pigeonhole (the plugin that provides SIEVE capability) should really be a separate package.  Their releases usually but not always occur simultaneously. so pigeonhole package, if/when we separate it from dovecot, will be a potential consumer.

[Comment 4 Philippe Chaintreuil 2022-07-24 12:30:22 UTC]

Came to +1 this.  I have a plugin in the GURU repo (net-mail/dovecot-fts-xapian) that needs to be rebuilt every time Dovecot gets rebuilt.

[Comment 5 Philippe Chaintreuil 2023-04-20 14:00:11 UTC]

"equery depends -a net-mail/dovecot" brings up this list for me (summarized):

mail-filter/maildrop (dovecot ? net-mail/dovecot)
net-mail/dovecot-fts-xapian (net-mail/dovecot) [GURU]
sys-cluster/poolmon (net-mail/dovecot)

I threw up a Github PR in case it makes anyone's life easier or restarts a conversation about pros/cons/gotchas.
