Hi,
I was able to reproduce the issue with 3.0.5 with these settings: unixhierarchysep: yes altnamespace: no crossdomains: no Key factor is unixhierarchysep on. (crossdomains is a special case. altnamespace on/off only looks different.) I did a lot of debugging and found out the following: Compared to version 2.4.x and 2.5.x 3.0.x function list_data in ../imap/imapd.c does not transform the hierarchy separator. In function mboxlist_do_find (../imap/mboxlist.c) below "Other Users namespace" we have a prefix search. With "unixhierarchysep on" cyrus uses the wrong prefix (domainpat) for that search. Example: . LIST "" "user/%" * LIST (\HasChildren) "/" user/bbb . OK Completed (0.000 secs 4 calls) . LIST "" "user/bbb/sub01" . OK Completed (0.000 secs) In this case cyrus searches with domainpat: user.bbb/sub01/subsub01 The prefix is previously generated from a variable called commonpat, which is used only for this specific search. So I fixed it there with this patch: --- cyrus-imapd-3.0.5/imap/mboxlist.c.orig 2018-04-12 13:12:47.633956338 +0200 +++ cyrus-imapd-3.0.5/imap/mboxlist.c 2018-05-30 10:56:44.255724710 +0200 @@ -2774,6 +2774,10 @@ const char *pat = strarray_nth(patterns, i); if (pat[prefixlen] != c) break; } + if (rock->namespace->hier_sep == '/') { + if (c == '/') c = '.'; + else if (c == '.') c = DOTCHAR; + } if (i < patterns->count) break; if (c == '*' || c == '%' || c == '?') break; commonpat[prefixlen] = c; Now for the example above the search pattern is user.bbb.sub01 and the submailbox is returned correctly. . LIST "" "user/%" * LIST (\HasChildren) "/" user/bbb . OK Completed (0.000 secs 4 calls) . LIST "" "user/bbb/sub01" * LIST (\HasChildren) "/" user/bbb/sub01 . OK Completed (0.000 secs 2 calls) . LIST "" "user/bbb/%" * LIST (\HasChildren) "/" user/bbb/sub01 * LIST (\HasNoChildren) "/" user/bbb/sub.dot01 . OK Completed (0.000 secs 3 calls) . SUBSCRIBE "user/bbb/sub01" . OK Completed . LSUB "" "user/*" * LSUB () "/" user/bbb/sub01 . OK Completed (0.000 secs 1 calls) The patch works fine in my test environment and I see no caveats yet. I would be very nice if someone could check it :-) Best regards, Edda Am 15.05.18 um 10:37 schrieb marco@xxxxxxxxxx: Hi, after migrating from cyrus-imapd-2.4.17 to cyrus-imapd-3.0.6 we cannot view (other) users subfolders.
