[Dovecot] tests with metadata module
--Repost after subscription as list member ---
I made some tests with metadata support in dovecot 2.2.10. Previously I had dovecot 2.2.4 with external metadata plugin who work well.
I use dovecot with roundcube and roundcube plugins from kolab project . First, the feature activation was tricky and rather undocumented. I spent about half hour googling, after that I set:
imap_metadata = yes and mail_attribute_dict = file:%h/shared_metadata
I think you cold put those lines in the 20-imap.conf example file commented; that way will be easy for us to activate.
Because I changed the location of shared_metadata, all folders was unannotated . I went in folder manager in roundcube and set folder "calendar" as calendar type and so on. That worked and i have:
cat shared_metadata: shared/c4268a04da44bb527c5b0000193e0904/vendor/kolab/folder-type event shared/cd5792367fc9cd5196170000193e0904/vendor/kolab/folder-type event shared/33f55d2e8912195209290000193e0904/vendor/kolab/folder-type event shared/32f55d2e8912195209290000193e0904/vendor/kolab/folder-type contact
However, it looks like the metadata is not properly read after. Calendar and Contacts folders don't appear in roundcube. I have this crash in dovecot's log:
Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x67d81) [0xb7625d81] -> /usr/lib/dovecot/libdovecot.so.0(+0x67e11) [0xb7625e11] -> /usr/lib/dovecot/libdovecot.so.0(i_fatal+0) [0xb75d6af9] -> dovecot/imap() [0x805d3b2] -> dovecot/imap() [0x805d5bc] -> dovecot/imap() [0x805d6c9] -> dovecot/imap(client_handle_input+0x56) [0x805d836] -> dovecot/imap(client_input+0x72) [0x805dcc2] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x38) [0xb7638d98] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0x10e) [0xb7639d6e] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x48) [0xb7638818] -> /usr/lib/dovecot/libdovecot.so.0(master_service_run+0x28) [0xb75dcb68] -> dovecot/imap(main+0x284) [0x8050f34] -> /lib/libc.so.6(__libc_start_main+0xf5) [0xb743f5a5] -> dovecot/imap() [0x80510a5] Dec 26 09:28:49 imap(mihai.badici): Fatal: master: service(imap): child 4919 killed with signal 6 (core dumps disabled)
I logged imap sessions in roundcube and I have:
A0003 GETMETADATA "*" (/private/vendor/kolab/folder-type /shared/vendor/kolab/folder-type)
On a similar server with the "old" metadata plugin, I have here listed all folders with coresponding annotations.
How I can debug further? This is a test server so I can stress it.

It worked after I changed here : file:%s/shared_metadata
A new folder "imap" was created and the "shared_metadata" file is in that
folder. With previous settings that file was in the mailbox root directory
and was not properly readed.

It worked after I changed here : file:%s/shared_metadata I made some investigation and I found Roundcube perform a GETMETADATA "*" (/private/vendor/kolab/folder-type)
to list all special folders. In cmd-getmetadata.c there is a "if" (line 455) who is intended, I think, to avoid the use of wildcards in mailbox name, but at the end the result is an attempt to open a NULL mailbox name who produce the crash. When I remove this condition and recompile dovecot, there are no crashes.
It's not clear for me if GETMETADATA "*" is still legal (there is a reference to rfc 5464 in the code) ; but in both cases there is a bug in the code.

This is indeed not specified in RFC5464, but it was in ANNOTATEMORE extension draft. This is very handy and it is supported by Cyrus.

I will check further. Dovecot crashes only in some particular conditions but it looks like is related with this "*" . There are values for " mail_location" and "mail_attribute_dict" who crash dovecot. With:
mail_location = maildir:~/MAILDIR and
mail_attribute_dict= file:%u/shared_metadata
dovecot works well.
So I think the fix is applied but there is a side effect remaining.

This issue strike again I think. I upgraded to dovecot 2.2.12 ( from 2.2.10) and when trying to access calendar I have this error in roundcube:
Invalid argument supplied for foreach() in /usr/share/roundcubemail-1.0/plugins/libkolab/lib/kolab_storage.php on line 1040
When I look at the code, I find the argument came from this call: $folders = self::$imap->get_metadata('*', array(kolab_storage::CTYPE_KEY_PRIVATE));
which means the getmetadata with wildcard was not working again ....
