LIST command hides mailboxes in certain cases, children attribute is wrong

Hello,

I've done some tests using Cyrus IMAP 3.2.6-Debian-3.2.6-2~bpo10+1 with 
enabled virt- and crossdomain support.
I've done the tests running two identical installations, the first one 
without defaultdomain configured, the second one with defaultdomain 
default.com configured.

Two things are weird. LIST command hides mailboxes in certain cases and 
folders with domain part have always no children.

I've added line numbers, let me show you what I mean:


1  . create user/user.one
2  . OK [MAILBOXID (ih9cx8siiy19flip9fhk7j6f)] Completed
3  . create user/user.one/one
4  . OK [MAILBOXID (rc97nsp4h2ipa08o1x4mg9bb)] Completed
5  . create user/[email protected]
6  . OK [MAILBOXID (wya2ura60ha87uppcvfc33tg)] Completed
7  . list "" "user/*"
8  * LIST (\HasNoChildren) "/" user/[email protected]
9  * LIST (\HasChildren) "/" user/user.one
10 * LIST (\HasNoChildren) "/" user/user.one/one
11 . OK Completed (0.000 secs 3 calls)

That looks pretty good, created three folders, three folders listed, one 
has a child (line 9).

12 . create user/user.one/[email protected]
13 . OK [MAILBOXID (7o4j2umwlc319t9wnel09gcs)] Completed
14 . list "" "user/*"
15 * LIST (\HasNoChildren) "/" user/[email protected]
16 * LIST (\HasNoChildren) "/" user/user.one/[email protected]
17 * LIST (\HasNoChildren) "/" user/user.one/one
18 . OK Completed (0.000 secs 4 calls)

Created one child folder, four folders created but three listed. One 
listed folder has a child but is listed with no children attribute (line 
15).

19 . create user/[email protected]
20 . OK [MAILBOXID (m9nilk5p4p8yb4z3ngcgp94k)] Completed
21 . list "" "user/*"
22 * LIST (\HasNoChildren) "/" user/[email protected]
23 * LIST (\HasNoChildren) "/" user/user.one/[email protected]
24 * LIST (\HasNoChildren) "/" user/[email protected]
25 * LIST (\HasChildren) "/" user/user.one
26 * LIST (\HasNoChildren) "/" user/user.one/one
27 . OK Completed (0.000 secs 5 calls)

Created a second parent folder for domain.com, five folders created, 
five folders listed, missing folder is back and has a child (line 25). 
The folder for [email protected] is listed with no children attribute 
(line 22), which is wrong.

Both test servers behave equal.




I've changed the test, using full qualified folder names, one is the 
defaultdomain default.com.

This is the output from the second server, which has defaultdomain 
configured:


1  . create user/[email protected]
2  . OK [MAILBOXID (cy26z9y9k07llbyy14zkwgsa)] Completed
3  . create user/user.one/[email protected]
4  . OK [MAILBOXID (a4af5crjeej4csosf9e6os8s)] Completed
5  . create user/[email protected]
6  . OK [MAILBOXID (0ehqz764zxntr6x3f1cur61v)] Completed
7  . list "" "user/*"
8  * LIST (\HasNoChildren) "/" user/[email protected]
9  * LIST (\HasChildren) "/" user/user.one
10 * LIST (\HasNoChildren) "/" user/user.one/one
11 . OK Completed (0.000 secs 3 calls)

That looks ok.

12 . create user/user.one/[email protected]
13 . OK [MAILBOXID (pn5xr9dl63kt9osncleyzydg)] Completed
14 . list "" "user/*"
15 * LIST (\HasNoChildren) "/" user/[email protected]
16 * LIST (\HasNoChildren) "/" user/user.one/[email protected]
17 * LIST (\HasNoChildren) "/" user/user.one/one
18 . OK Completed (0.000 secs 4 calls)

One folder is missing.

19 . create user/[email protected]
20 . OK [MAILBOXID (o7g52uu5frc4kyanyjdnbgfd)] Completed
21 . list "" "user/*"
22 * LIST (\HasNoChildren) "/" user/[email protected]
23 * LIST (\HasNoChildren) "/" user/user.one/[email protected]
24 * LIST (\HasNoChildren) "/" user/[email protected]
25 * LIST (\HasChildren) "/" user/user.one
26 * LIST (\HasNoChildren) "/" user/user.one/one
27 . OK Completed (0.000 secs 5 calls)

Missing folder is back, children attribute is wrong for domain.com (line 
22).

The output from the first server, without defaultdomain configured, 
looks ok except children attribute.

14 . list "" "user/*"
15 * LIST (\HasNoChildren) "/" user/[email protected]
16 * LIST (\HasNoChildren) "/" user/user.one/[email protected]
17 * LIST (\HasNoChildren) "/" user/[email protected]
18 * LIST (\HasNoChildren) "/" user/user.one/[email protected]
19 . OK Completed (0.000 secs 4 calls)




Third test using full qualified folder names and domains other than 
default.com:


14 . list "" "user/*"
15 * LIST (\HasNoChildren) "/" user/[email protected]
16 * LIST (\HasNoChildren) "/" user/user.one/[email protected]
17 * LIST (\HasNoChildren) "/" user/[email protected]
18 * LIST (\HasNoChildren) "/" user/user.one/[email protected]
19 . OK Completed (0.000 secs 4 calls)


Both test servers behave equal. All folders are listed, children 
attributes are wrong (lines 15,17).


I've done the tests using Cyrus IMAP 3.4.2, same results.

Is there something I'm doing wrong or is it a bug?


Thx
Adam
