Hi. I was on my way to backport commit 210485dd5592bf23ac9335a2d3f5711e62753605
to my local 3.0.2 branch but
faced and inconvenience between old and new SQL query results:
Mailbox contents:

2;

Old query:
mysql> SELECT 0,COUNT(*) FROM dbmail_messages WHERE mailbox_idnr=109 AND (status
< 2) UNION SELECT 1,COUNT(*) FROM dbmail_messages WHERE mailbox_idnr=109
AND (status < 2) AND seen_flag=1 UNION SELECT 2,COUNT(*) FROM dbmail_messages
WHERE mailbox_idnr=109 AND (status < 2) AND recent_flag=1;
+---+----------+
| 0 | COUNT(*) |
+---+----------+
| 0 | 8 | <-- exists
| 1 | 2 | // unseen = exists - this = 8 - 2 = 6
| 2 | 6 | <-- recent
+---+----------+
New query:
mysql> SELECT CASE WHEN seen_flag+recent_flag = 0 THEN 0 WHEN seen_flag = 1
THEN 1 WHEN recent_flag = 1 THEN 2 END AS flag, COUNT(*) FROM dbmail_messages
WHERE mailbox_idnr=109 AND (status < 2) GROUP BY seen_flag, recent_flag;
+------+----------+
| flag | COUNT(*) |
+------+----------+
| 0 | 2 | // exists = 2 + 4 + 2 = 8
| 2 | 4 | <-- recent
| 1 | 2 | // unseen = exists - this = 8 - 2 = 6
+------+----------+
As you can see recent message number differs. What is the correct number of
recent messages?
Should they be counted according to recent_flag value only?
