[Dovecot] namespace from snapshots

[Lazy]

I managed to get it working using a litle change in sources
an extra mailbox_list_subscription_fill_one(dest_list, src_list, "" );
in src/lib-storage/list/mailbox-list-subscriptions.c:mailbox_list_subscriptions_refresh()

--- src/lib-storage/list/mailbox-list-subscriptions.c   (wersja 494)
+++ src/lib-storage/list/mailbox-list-subscriptions.c   (kopia robocza)
@@ -142,6 +142,9 @@
        subsfile_ctx = subsfile_list_init(dest_list, path);
        if (subsfile_list_fstat(subsfile_ctx, &st) == 0)
                dest_list->subscriptions_mtime = st.st_mtime;
+
+       mailbox_list_subscription_fill_one(dest_list, src_list, "" );
+
        while ((name = subsfile_list_next(subsfile_ctx)) != NULL) T_BEGIN {
                T_BEGIN {
                        ret = mailbox_list_subscription_fill_one(dest_list,


now lsub works as expected, namespace root which is an INBOX from a
snapshot is subscribed, all the subfolders are also subscribed (from
original subscriptions file).


It whould be great if one could specify in the namespace mailboxes
that whould get autosubscribed or just to autosubscribe root whitch is
what You need if You have a copy of Maildir with INBOX. If You think
this can be usefull I will try to produce more general patch
automagicly subscribing root or any other mailbox in an namespace.
