Here's an update on the testing and new cyrus patches at FastMail.FM. Thanks to 2.3.9 being recently released, we've been going crazy with all the little things that we want different. There's still plenty more to come, but I'm trying to keep them published frequently so anyone can check them any time.
http://cyrus.brong.fastmail.fm/ Now with changelogs! (strictly, it's the output of "svn log" on the patch file in question, going back only until I created the quilted versions because I imported the patches into quilt and didn't connect the history.) Anyway, here's what's new since last time I posted: * updated rehash script which can parse all possible disk layouts and move everything to any other layout. * fast rename fix - it used the old "rmdir() up the tree until it fails" method of cleaning up the old folder path. This has the unfortunate side-effect of nuking data directories for empty but still present folders. Changed it to use the same logic as mailbox_delete() (by refactoring said logic). This was particularly evident with the major mess created by the 15k deep empty mailbox structure created by the issue addressed below and the attempts to delete with rename/delete enabled. * Clean shutdown is now in production and we're very happy with it so far. Shutdown is always finished within the first second. * New patch adds option "user_folder_limit: INT" - the user will get permission denied if they try to create more than that number of folders. This was created because a user managed to import 15000 individual files as mailboxes via UW-IMAP and our migration tool. Ouch. We realised there's a denial of service risk there, so this option allows us to limit our users to a sane amount (we already limit them in our web interface, but they have direct IMAP access as well) As always, feedback is very welcome. Spelling flames for my SVN changelog entries less so, I didn't expect to publish them ;) Enjoy, Bron.
