[Dovecot] dovecot-2.2: broken domain quota calculation

Hello.

Used next version of dovecot:

# dovecot --version 20130205 (03a0af22100d+)

Quota configuration:

plugin { quota = dict:Domain quota:%d:redis:host=127.0.0.1:prefix=domain/ quota_rule = *:storage=0 quota_rule2 = Trash:storage=+5%% quota2 = dict:User quota::redis:host=127.0.0.1:prefix=user/ quota2_rule = *:storage=0 quota2_rule2 = Trash:storage=+5%% }

Problem: incorrect quota calculations. Dovecot gets size and messages count of all domain from last user in list. In 2.1 works fine.

Steps to reproduce problem:

1. install dovecot

2. create over 50 users with e-mails

3. execute: doveadm quota recalc -A

4. execute: doveadm quota get -A

5. get count of all users message: sum in some application result of execution doveadm quota get -A | grep MESSAGE | grep 'User quota' | awk '{print $5}' (139443 messages)

6. get size of all users message: sum in some application result of execution doveadm quota get -A | grep STORAGE | grep 'User quota' | awk '{print $5}' (2304399 Kb)

7. look at some user

   user@example.org Domain quota STORAGE 82408 51200000
   0 user@example.org Domain quota MESSAGE 1078

   0 user@example.org User quota STORAGE 0 209715200
   0 user@example.org User quota MESSAGE 0

   0

   and see 1078 messages and 82408 Kb in domain quota

8. look at last user in list

   z@example.org Domain quota STORAGE 82408 51200000
   0 z@example.org Domain quota MESSAGE 1078

   0 z@example.org User quota STORAGE 82408 209715200
   0 z@example.org User quota MESSAGE 1078

   0

   and see matching values.
