doveadm force-resync does not work

[jrse]

current implementation to rebuild index is based on sdbox. It needs to be rewritten to list all objects (mail) for given mailbox from rados and add each file to rebuild index again.

Note:

• calling doveadm force-resync on valid index, will do nothing. Current behavior of force resync is to create backup of original index and log files. rebuild index is empty after force-resync.
• attached you find t1's corrupt mailbox (unable to copy more than one mail from inbox to another folder)

The following function needs to be modified.

rbox-sync.cpp
static int rbox_sync_index_rebuild_dir(struct index_rebuild_context *ctx, const char *path, bool primary).
(based on sdbox-sync.cpp) sdbox_sync_index_rebuild....

rebuild of index is done in the following way:
doveadm force-resync -u
this will trigger the following process.

1. mailbox.guid is determined (existing index file)
2. resync search for all objects with attribute M=mailbox.guid
3. resync loads all xattributes for each object.
4. resync tries to find old index entry with xattribute.UID in backup index / log.
5. resync restores index entry
6. resync re-adds the extension header with oid and xattributes.guid
