mdbox: Delay getting permissions for map/message files. This avoids a stat() if no mailbox is opened.

lib-storage: mailbox_list_get_root_permissions() now returns struct mailbox_permissions.

Array API changed: ARRAY_DEFINE(name, type) -> ARRAY(type) name Easy way to update your existing code: perl -i -pe 's:ARRAY_DEFINE\(([^,]+), *([^)]+)\);:ARRAY($2) $1;:' **/*.[ch]

mdbox: Make sure map transaction won't succeed after mdbox_map_atomic_set_failed()

mdbox: Make sure m.* files aren't overwritten when storage index isn't found. This mainly helps to avoid situations where m.1 is replaced by mail delivery when index directory has been (wrongly) changed.

mdbox: If :INDEX=path is specified, keep storage indexes there also.

mdbox: Modified map locking behavior to avoid deadlocks when rebuilding storage. If both mailbox and map index need to be locked, the map index must now be locked first. Mailbox syncing optimistically tries to first sync without map locking, but if it sees expunges, it restarts with the map lock. The map lock is held now slightly longer during sync than before, but it shouldn't be noticeable. --HG-- branch : HEAD

dbox, mdbox: Fixed race conditions when creating mailboxes. --HG-- branch : HEAD

When creating shared directories, preserve parent dir's permissions if it has setgid bit enabled. This works only if location path uses %variables. The directories up to last variable are created by preserving parent directory's modes, while the rest of the directories are created with 0700. For example with "/var/mail/%d/%2n/%n/Maildir", "/var/mail/domain/nn" preserves /var/mail's permissions, while the "username/Maildir" directories have 0700 mode. --HG-- branch : HEAD

mdbox: Renamed dbox_map* to mdbox_map*. --HG-- branch : HEAD

mdbox: Moving messages to alt storage is done done with doveadm altmove command. The command can take an arbitrary search query listing what messages should exist in alt storage. If the message has been copied to multiple mailboxes, the search query must match all the instances of the message. Since the search query can now be specified in command line, mdbox_altmove setting was also removed. --HG-- branch : HEAD

mdbox: Purging now also moves mails to alt storage (if it's used). mdbox_altmove setting specifies how old files should be moved. --HG-- branch : HEAD

Split dbox (single-dbox) and mdbox (multi-dbox) into separate storage backends. This cleans up the code, makes it faster and also fixes some bugs. Super-fast maildir migration code was also dropped, at least for now. --HG-- branch : HEAD
