1.0.rc24 released

And more fixes. * Dovecot now fails to load plugins that were compiled for different Dovecot version, unless version_ignore=yes is set. This needs to be explicitly set in plugins, so out-of-tree plugins won't have this check by default. - pop3_lock_session=yes could cause deadlocks, and with maildir the uidlist lock could have been overridden after 2 minutes causing problems - PAM wasted CPU by calling a timeout function 1000x too often - Trash plugin was more or less broken with multiple namespaces and with multiple trash mailboxes

http://dovecot.org/releases/dovecot-1.0.rc23.tar.gz http://dovecot.org/releases/dovecot-1.0.rc23.tar.gz.sig Documentation is probably the only important thing left before v1.0. * deliver doesn't ever exit with Dovecot's internal exit codes anymore. All its internal exit codes are changed to EX_TEMPFAIL. * mbox: X-Delivery-ID header is now dropped when saving mails. * mbox: If pop3_uidl_format=%m, we generate a unique X-Delivery-ID header when saving mails to make sure the UIDL is unique. + PAM: blocking=yes in args uses an alternative way to do PAM checks. Try it if you're having problems with PAM. + userdb passwd: blocking=yes in args makes the userdb lookups be done in auth worker processes. Set it if you're doing remote NSS lookups (eg. nss_ldap problems are fixed by this). + If PAM child process hasn't responded in two minutes, send KILL signal to it (only with blocking=no) - IMAP: APPEND ate all CPU while waiting for more data from the client (broken in rc22) - mbox: Broken X-UID headers assert-crashed sometimes - mbox: When saving a message to an empty mbox file it got an UID which immediately got incremented. - mbox: Fixed some wrong "uid-last unexpectedly lost" errors. - auth cache: In some situations we crashed if passdb had extra_fields. - auth cache: Special extra_fields weren't saved to auth cache. For example allow_nets restrictions were ignored for cached entries. - A lot of initial login processes could cause auth socket errors in log file at startup, if dovecot-auth started slowly. Now the login processes are started only after dovecot-auth has finished initializing itself. - imap/pop3 proxy: Don't crash if the remote server disconnects before we're logged in. - deliver: Don't bother trying to save the mail twice into the default mailbox (eg. if it's over quota). - mmap_disable=yes + non-Linux was really slow with large dovecot.index.cache files - MySQL couldn't be used as a masterdb - Trash plugin was more or less broken - imap/pop3 couldn't load plugins if they chrooted - imap/pop3-login process could crash in some conditions - checkpassword-reply crashed if USER/HOME wasn't set

1.0.rc22 released

http://dovecot.org/releases/dovecot-1.0.rc22.tar.gz http://dovecot.org/releases/dovecot-1.0.rc22.tar.gz.sig Found another bad bug in rc19 changes. Wonder why my imaptest catched the bug only in CVS HEAD but not in branch_1_0 even though both had it. Anyway, now the imaptest runs nicely for both, and I'm again optimistic that the bug count is low enough for v1.0 to be released soon :) BTW. My previous benchmarks which showed how mmap_disable=yes and fsync_disable=yes give huge performance benefits are pretty XFS-specific. I did some quick tests with ext3 and the differences were quite small with it. I'll probably do another proper run of tests later. + pop3: Commit the transaction even if client didn't QUIT so cached data gets saved. - Fixed another indexing bug in rc19 and later which caused transactions to be skipped in some situations, causing all kinds of problems. - mail_log_max_lines_per_sec was a bit broken and caused crashes with dovecot -a - BSD filesystem quota was counted wrong. Patch by Manuel Bouyer - LIST: If namespace has a prefix and inbox=no, don't list prefix.inbox if it happens to exist when listing for %.

http://dovecot.org/releases/dovecot-1.0.rc21.tar.gz http://dovecot.org/releases/dovecot-1.0.rc21.tar.gz.sig Just one fix. Maybe the one big thing in Dovecot v2.0.* will be a test suite, which is run before any release. :) - Cache file handling could have crashed rc20

1.0.rc20 released

http://dovecot.org/releases/dovecot-1.0.rc20.tar.gz http://dovecot.org/releases/dovecot-1.0.rc20.tar.gz.sig So, rc19 was somewhat broken. How about this version? + dovecot: Added --log-error command line option to log an error, so the error log is easily found. + Added mail_log_max_lines_per_sec setting. Change it to avoid log throttling with mail_log plugin. - Changing message flags was more or less broken in rc19 - ACL plugin still didn't work without separate control directory - Some mbox handling fixes, including fixing an infinite loop - Some index file handling fixes - maildir quota: Fixed a file descriptor leak - If auth_cache was enabled and userdb returned "user unknown" (typically only deliver can do that), dovecot-auth crashed. - mail_log plugin didn't work with pop3
