Marked functions parameters that are allowed to be NULL. Some APIs were also changed. The non-obvious APIs where NULL parameter was changed to "" are master_service_init() and auth_master_user_list_init(). These checks can currently be enabled only on a patched clang: http://llvm.org/bugs/show_bug.cgi?id=6786

maildir: Whenever we're guessing a filename correctly, remember it in uidlist.

Moved GUID code to liblib. Use guid_128_t type consistently everywhere.

lib-storage: Added MAIL_FETCH_POP3_ORDER special field and implemented for Maildir. The idea is that this specifies the order of messages when accessing via POP3. This is useful when migrating both POP3 and IMAP users from servers where their message ordering differes and they still want to be preserved.

maildir: Remove invalid extension records from dovecot-uidlist. For now we'll assume that if the key is outside A..Z it's invalid. Since only 4 keys are used currently, there is still a lot of letters available for future use.

Maildir: If mail's virtual size can be found from filename/uidlist, do it instead of using cache. This is especially useful with POP3 to avoid opening cache file.

maildir: uidlist can now override message's GUID

maildir: maildir_uidlist_lookup() -> maildir_sync_lookup() refactoring.

lib-storage: *_mailboxes don't descend from index_mailbox anymore, it's now a context. --HG-- branch : HEAD

Removed MAILBOX_GUID_SIZE macro, use MAIL_GUID_128_SIZE everywhere. They were required to be the same size anyway. --HG-- branch : HEAD

maildir: Support saving messages with specified UIDs. --HG-- branch : HEAD

Added support for creating/updating mailboxes with given metadata (guid, uid validity, etc). --HG-- branch : HEAD

Added support for mailbox GUIDs. --HG-- branch : HEAD

Maildir: More fixes to uidlist handling. --HG-- branch : HEAD

Maildir: Handle uidlist errors better. --HG-- branch : HEAD

Added maildir_very_dirty_syncs setting. --HG-- branch : HEAD

dbox: Removed code that is no longer necessary with the redesign. - Maildir code now uses dovecot-uidlist directly instead of dbox.index. - Flags and keywords are no longer written to metadata. - Removed metadata modifying code entirely. - dbox.index is no longer read or written. The code will be removed soon. --HG-- branch : HEAD

maildir: Allow opening mailbox and expunging messages when uidlist couldn't be locked (e.g. out of quota). --HG-- branch : HEAD

Maildir: Uidlist stale timeout macro is now globally available. --HG-- branch : HEAD

Maildir: If dovecot-uidlist has wrong cached virtual size, remove it when we detect it. If maildir filename has wrong W value, log a clear error about it. --HG-- branch : HEAD

Keep track of dovecot-uidlist mtime+size in index file. If it's up-to-date (and unless indexes weren't updated at some point, it always is) and we're saving a new message, don't bother reading the uidlist contents. --HG-- branch : HEAD

Store physical message sizes also to dovecot-uidlist if needed. --HG-- branch : HEAD

If file is lost, don't try to look for it until stack overflows. --HG-- branch : HEAD

Removed pointless maildir_uidlist_sync_next_pre() calling. --HG-- branch : HEAD

If we're doing a fast sync, try only once to lock uidlist. --HG-- branch : HEAD

maildir_storage_sync_force(): Don't wait on trying to lock uidlist. Just try once and if it fails, find the changed filenames and do nothing else. --HG-- branch : HEAD

Delayed NFS attribute cache flushing had some bug, so removed it for now. --HG-- branch : HEAD

NFS: Delay flushing dovecot-uidlist's attribute cache until we find an unseen file or UID. --HG-- branch : HEAD

#ifndef typofix --HG-- branch : HEAD

Added maildir_uidlist_init_readonly() and maildir_uidlist_get_uid(). --HG-- branch : HEAD

Changed .h ifdef/defines to use <NAME>_H format. --HG-- branch : HEAD

Changed *_deinit() APIs to take ** pointer and set it to NULL. --HG-- branch : HEAD

Recent flag handling rewrite. Still not perfect with maildir. --HG-- branch : HEAD

Fixed reassigning new UIDs to more than one message. --HG-- branch : HEAD

Added support for updating uidlist record extensions. --HG-- branch : HEAD

Created a new extensible version 3 dovecot-uidlist file. --HG-- branch : HEAD

maildir_uidlist_iter_next() should return bool, not int. --HG-- branch : HEAD

Handle next_uid changes better. --HG-- branch : HEAD

Added maildir_uidlist_sync_remove() --HG-- branch : HEAD

cleanup: s/maildir_uidlist_update()/maildir_uidlist_refresh()/ --HG-- branch : HEAD

Removed unused MAILDIR_UIDLIST_SYNC_ORDERED flag. --HG-- branch : HEAD

When saving/copying mails, we must not do any sorting based on the filename to saved mails when they're added to uidlist, otherwise they could be saved to index with wrong UID. --HG-- branch : HEAD

If uidlist is deleted and we set the uidvalidity from the index file, set also next_uid. --HG-- branch : HEAD

If pop3_lock_session=yes, update maildir/dbox uidlist lock file every 10 seconds so it won't be treated as a stale lock. --HG-- branch : HEAD

Added maildir_copy_preserve_filename setting. --HG-- branch : HEAD

Don't go fixing duplicate maildir filenames without properly checking that they really are such. --HG-- branch : HEAD

Adding mail to index while saving it had a race condition. Fixing it required a bit larger changes. Switched uidlist/index locking order so that uidlist is now locked first. --HG-- branch : HEAD

Added "bool" type and changed all ints that were used as booleans to bool. --HG-- branch : HEAD

Recursive maildir uidlist syncs caused assert crashes. Also did some cleanups. --HG-- branch : HEAD

Keywords are stored in maildir filename and maildir-keywords file (backwards compatible with 0.99.x's .customflags file) --HG-- branch : HEAD

Moved mbox/maildir-specific variables from struct index_mailbox to mbox_mailbox and maildir_mailbox. --HG-- branch : HEAD

Recent flags should be fully working now with maildir. --HG-- branch : HEAD

UIDs for appended messages can now be assigned all at once. Maildir now updates indexes immediately while saving messages. --HG-- branch : HEAD

locking fixes --HG-- branch : HEAD

race condition fixes --HG-- branch : HEAD

Some more UIDVALIDITY issues fixed. --HG-- branch : HEAD

Index header changes now go through transaction log. Removed the kludgy parameters for mail_index_sync_end(). Removed code duplication of syncing index root mapping and view mapping. Some fixes to handling uidvalidity and nextuid in syncing. --HG-- branch : HEAD

syncing fixes --HG-- branch : HEAD

syncing fixes --HG-- branch : HEAD

mbox code compiles again, but syncing is only partially implemented so accessing mboxes fails.. Also some cleanups to index-storage and maildir code. --HG-- branch : HEAD

Syncing optimizations. --HG-- branch : HEAD

Recent-flag should work now --HG-- branch : HEAD

importing new index code. mbox still broken. --HG-- branch : HEAD
