If I delete a mailbox selected by the current IMAP session in 2.4.X then
the underlying files are are only removed on logout. I suspect that this
is a consequence of the new mailbox code, which is fair enough.
I have however discovered two wrinkles when deleting mailboxes selected by
some other IMAP session. PINE might leave a mailbox selected for days.
1) Deleted mailboxes remained locked:
=====================================
If I delete a mailbox which is selected (either in the current IMAP
session or some completely unrelated session) then it is not possible to
create a new mailbox with the same name:
C1:
. SELECT foo
C2:
. DELETE foo
. OK Completed
. CREATE foo
. NO Mailbox is locked
until any sessions which have the old mailbox selected are shut down.
2) Debris left on the filesystem
================================
If I DELETE a mailbox which is selected in a separate IMAP session:
C1:
. SELECT foo
C2:
. DELETE foo
. OK Completed
. LOGOUT
C1:
. LOGOUT
The cyrus.* and messages files are left on disk, and overwritten in place
when a subsequent login session creates a mailbox with the same name.
Is this deliberate?
I suppose that the only real danger is that reconstruct might resuscitate
messages belonging to an earlier version of a mailbox with the same name.
