The Big Rewrite. too many change to list them all. as opposed to earlier threats, BerkDB was not entirely dropped; i suppose the isync 0.7 -> 0.8 change had a reason, so i added an alternative UID storage scheme. note that BDB 4.0 is not sufficient, as the db->open function changed in an incompatible way ... i updated the debian packaging except for a changelog entry. note that i removed the upgrade blurb, as upstream now has a smooth upgrade path down to at least isync 0.4.

updated year in copyright notice the uid for each message in the maildir is now stored in a dbm database rather than the filename. this change was necessary because isync became confused if you copied a message to another folder, in which case the uid was invalid. as a result of the above change, isync now acquires a mutex on the mailbox to protect the dbm database from concurrent access. main() was reworked to continue gracefully when an error is encountered, and to always call maildir_close() so that the lock can be disabled, and the database closed.

Bunch 'o patches from Oswald Buddenhagen: i implemented some cool stuff (tm). first, the long missing "create server-side missing mailboxes". -C now creates both local and remote boxes; -L and -R create only local/remote. second, i implemented a 1:1 remote:local folder mapping (-1) with an optional INBOX exception (inbox/-I). the remote folder is specified with the folder keyword (or -F switch) and takes precedence over the namespace setting. the local directory with the mailboxes can now be specified on the command line, too (-M). another patch: - made the -1 switch settable permanently (OneToOne). after all, you usually define your mailbox layout once forever. removed -A, as it is semantically -a modified by -1. - cleaned up message output a bit. still, the quiet variable should be used throughout the program. at best, create some generic output function, which obeys a global verbosity level variable. - optimized + cleaned up configuration parser slightly - minor cleanups add an (almost) unique id to every uploaded message and search for it right after. i thought about using the message-id, but a) it is not guaranteed to be unique in a mailbox (imagine you edit a mail and store the dupe in the same box) and b) some mails (e.g., postponed) don't even have one. a downside of the current implementation is, that this id-header remains in the mailbox, but given that it wastes only 27 bytes per mail and removing it would mean several roundtrips more, this seems acceptable. i changed the line-counting loop to use a mmapped file instead of reading it in chunks, as it makes things simpler and is probably even faster for big mails. the amount of goto statements in my code may be scary, but c is simply lacking a multi-level break statement. :) this is the "shut up" patch. :) it makes the -q option consequent, so to say. additionally it adds an -l option which gathers all defined/found mailboxes and just outputs the list. don't ask what i need it for. ;)

updated year in copyright notice the uid for each message in the maildir is now stored in a dbm database rather than the filename. this change was necessary because isync became confused if you copied a message to another folder, in which case the uid was invalid. as a result of the above change, isync now acquires a mutex on the mailbox to protect the dbm database from concurrent access. main() was reworked to continue gracefully when an error is encountered, and to always call maildir_close() so that the lock can be disabled, and the database closed.

The Big Rewrite. too many change to list them all. as opposed to earlier threats, BerkDB was not entirely dropped; i suppose the isync 0.7 -> 0.8 change had a reason, so i added an alternative UID storage scheme. note that BDB 4.0 is not sufficient, as the db->open function changed in an incompatible way ... i updated the debian packaging except for a changelog entry. note that i removed the upgrade blurb, as upstream now has a smooth upgrade path down to at least isync 0.4.
