Folder subscription issue

By the way I think I found some more…..

When a sync_client in user mode… creates a non existing user in the replica… if the user has a dot… the quota gets properly created, but seen, sub files are wrongly created… for instance….

-rw-------   1 cyrus  cyrus  2576528 Jul 12 13:03 f.veiga.conversations
-rw-------   1 cyrus  cyrus       88 Jul 12 13:03 f.veiga.counters
-rw-------   1 cyrus  cyrus      451 Jul 12 10:43 f.veiga.sub
-rw-------   1 cyrus  cyrus       16 Jul 12 01:32 f.veiga.xapianactive
-rw-------   1 cyrus  cyrus     2584 Apr  3 01:48 f^veiga.seen
-rw-------   1 cyrus  cyrus      316 Apr  3 01:48 f^veiga.sub

The Apr 3 files are from the initial sync when the box was empty… the first ones (with the dot and not ^) are the actual files being used by Cyrus…. And updated with the replication and so…

It seems this to be the reason because I didn’t see in the initial sync any subscribed folders… but later when set them from a mua where properly replicated…

With Sieve seemed to happen something similar… but in this case with the ‘^’ and ‘.’ In the directory name….

It’s like the name used for creating the subscribing and seen databases in a user mode replication was not properly handled by Cyrus… because it does the same as with quota database with indeed with ‘^’ is properly created….

Thanks! Bye!

It’s a generally happening thing with rename of folders inside the own hierarchy inside the own user… (don’t really know if a rename mailbox for changing partition would have the same issue). Not something related to the Trash folder...
