Cyrus IMAP 2.0.x Release Notes ****************************** Changes to the Cyrus IMAP Server since 2.0.16 * migrated to SASLv2 (Rob Siemborski) * altnamespace: it is now possible to display user mailboxes as siblings to the INBOX at the top-level (Ken Murchison) * unixhierarchysep: it is now possible to use slash as the hierarchy separator, instead of a period. (Ken Murchison, inspired by David Fuchs, dfuchs@uniserve.com) * SSL/TLS session caching (Ken Murchison) * support for IMAP CHILDREN & LISTEXT extensions (Ken Murchison, work in progress) * check recipient quota & ACL at time of RCPT TO: in lmtpd (Ken Murchison) * support for LMTP STARTTLS & SIZE extensions (Ken Murchison) * unified deliver.db, using cyrusdb interface, hopefully improving concurrency and performance (Ken Murchison) * fixed STORE FLAGS () bug (Ken Murchison) * fixed SEARCH SUBJECT vs. SEARCH HEADER SUBJECT bug (Ken Murchison) * users without an INBOX can have subscriptions (Ken Murchison; noticing a trend here?) * added cyrusdb_db3_nosync backend, used for duplicatedb and session cache, to postpone non-critical writes. (Ken Murchison) * support for STARTTLS and AUTH=ANONYMOUS for timsieved (Ken Murchison) * do setgid and initgroups in master (as urged by several people) * added more config info to IMAP ID (in a vain attempt to improve debugging) * configure now checks for DB3.3 * SQUAT (Rob O'Callahan, roc@cs.cmu.edu) * change SEARCH HEADER x to SEARCH x utilizing internal cache where possible (Rob O'Callahan, roc@cs.cmu.edu) * an improved directory hashing option (Gary Mills, mills@cc.UManitoba.CA) * use of EGD for SSL/TLS (Amos Gouaux, amos@utdallas.edu) * separate certs/keys for services (Henning P. Schmiedehausen, hps@intermeta.de) * ability to force ipurge to traverse personal folders (Carsten Hoeger, choeger@suse.de) * fixed zero quota bugs in cyradm (Leena Heino, liinu@uta.fi) * ignore trailing whitespace in imapd.conf * Received: header (with TLS and AUTH info) * added '-i' switch to sendmail command line for SIEVE reject, redirect and vacation * small fixes to notify_unix * added "duplicatesuppression" switch to imapd.conf for enabling/disabling duplicate delivery suppression (Birger Toedtmann, birger@takatukaland.de) Changes to the Cyrus IMAP Server since 2.0.15 * fixed a longstanding bug in quota that would affect people with unusual top-level hierarchy, fix by John Darrow, John.P.Darrow@wheaton.edu. * some important fixes to db3 interface code, by Walter Wong wcw@cmu.edu, prompted by complaints from Scott Adkins adkinss@ohio.edu. * fixed some memory leaks in imclient and in the Perl IMAP module, prompted by Toni Andjelkovic toni@soth.at. * fixed a longstanding authentication error in the Perl IMAP module, should remove pesky extra Password: prompt. * fixed some allocation bugs in the managesieve perl module. Changes to the Cyrus IMAP Server since 2.0.14 * fixed memory management bugs in imapd, lmtpd that were being hit due to the connection reuse code and causing subtle and annoying problems. * we now clean up better when deleting a user * fixed an endian bug in ipurge * pop3d now can also reuse processes. * fix a bug in imclient that would strike when cyradm specifies a mechanism on the command-line. (SASL mechanism names aren't case sensitive.) * fix some bugs in handling SIGHUP in master * fix a couple of goofs in Admin.pm Changes to the Cyrus IMAP Server since 2.0.13 * fixed a silly bug with reusing SSL connections * lmtpd can now service multiple clients in sequence, hopefully improving performance * changed how Berkeley db databases are opened, hopefully lessening the chance of deadlock and improving performance * fixed a couple of memory leaks * lessened the chance of a race condition during index_check() Changes to the Cyrus IMAP Server since 2.0.12 * refactored code so less duplication * added alternate config file for partial virtual domain support * pop3d can now disable USER/PASS commands. * STARTTLS now accepts a SSLv23 hello but doesn't allow SSLv23 to be negotiated. * imtest no longer buffers to aid use as an automated layer. * master now supports maximum number of service processes via the "maxchild" modifier. * fixed a bug in the Sieve string lexer. * one imapd process can now service multiple clients in sequence, eliminating a large number of forks. Changes to the Cyrus IMAP Server since 2.0.11 * portability fixes involving setrlimit() * fixed compiler warnings * the STARTTLS command will only accept TLSv1 now, not SSLv2/v3. The imaps port is unaffected by this change. * timsieved no longer returns garbage strings. Changes to the Cyrus IMAP Server since 2.0.9 * some small memory savings * the "fud" daemon once again works correctly * the IDLE extension now uses signals correctly * problems with libwrap have been resolved * imapd and pop3d now log connections protected via TLS. * efficiency improvements when searching for a particular message-id * fixed an envelope-parsing bug affecting SORT and THREAD * made RENAME keep the same mailbox uniqueid, preserving seen state across renames * STOREing flags to multiple messages in one command is now more efficient * RENAME now preserves the ACL * LIST is now as efficient as Cyrus v1.6, modulo Berkeley DB issues. * Sieve zephyr notifications are now correct. * crash in reconstruct now fixed. * man pages added for cyrus.conf, master, lmtpd, idled, ctl_mboxlist, and ctl_deliver. * master can now listen on specific interfaces * master can now reread /etc/cyrus.conf on SIGHUP. * timsieved now uses symlinks instead of hard links. Changes to the Cyrus IMAP Server since 2.0.8 * remembered to update this file * bug in Cyrus::IMAP perl module affecting cyradm's setquota fixed * portability fix with socklen_t Changes to the Cyrus IMAP Server since 2.0.7 * preliminary implementation of the IDLE extension (Ken Murchison, ken@oceana.com). * THREAD=REFERENCES now part of the normal build. * tweaks to the installation documentation and suggested Sendmail configuration * portability fixes and other small bugfixes * added "-a" flag to lmtpd * master process can now export statistics about running processes via UCD SNMP AgentX * many fixes to Cyrus Murder-related code * fixes to perl code, especially the Sieve interface. added an IMSP interface to the perl code, but it still needs work. Changes to the Cyrus IMAP Server since 2.0.6 * some number of random static variables eliminated, to save on memory footprint * recursive RENAME was a little to eager; fixed. RENAME will also give the client a hint that a sub-RENAME failed. (mostly probably useful for cyradm, but cyradm doesn't take advantage of it yet.) * THREAD=X-JWZ has turned into THREAD=REFERENCES (Ken Murchison) * DELETE wasn't failing cleanly in database code; fixed. * off-by-one bug in seen_db fixed. * starting/committing/aborting transactions now logged more correctly in cyrsudb_db3 * master will now accept port numbers instead of just service names in cyrus.conf. also logs even more verbosely (see bug #115.) * libwrap_init() is now inside the loop, since i don't quite understand the semantics of libwrap calls. * setquota in cyradm now behaves more sanely (and gives correct usage message). * bugfixes to the managesieve client perl api. (still needs work.) * small fixes in timsieved. * added a "make dist" target so i won't dread releases as much. Changes to the Cyrus IMAP Server since 2.0.5 * APPEND now honors the Seen flag. * mailboxes file can once again be a flat text file. (compile-time choice) * subscriptions file can be flat text or berkeley db. likewise for seen state. * unfortunately, the format of the mailboxes file has changed. * implementation of "JWZ" threading, a first pass on the forthcoming THREAD=REFERENCES. * bugfixes in libacap. * bugfixes in other Murder related functionality. * removal of dead code. * will now look in CYRUS_PREFIX/etc/imapd.conf if there's no /etc/imapd.conf. * more paranoid implementation of ID. * more descriptive lmtp errors. * finished implementation of LMTP 8BITMIME. * fixed minor bugs in pop3d. * small test suite for cyrusdb backends added in lib/test/. * added -DPERL_POLLUTE to the perl compilation to deal with Perl 5.6. * small additions to the Sieve library. * As usual, owe lots of thanks to Ken Murchison for his hard work and awesome implementations. Changes to the Cyrus IMAP Server SINCE 2.0.4 * Now should work with Berkeley DB 3.1, but does not auto-upgrade 3.0 databases (and, in fact, I haven't written any upgrade software yet). * SORT and THREAD should now function correctly. * Some configure fixes. * Some fixes for possible race conditions in initializing services and database structures. * Some non-gcc compile fixes with structure initialization. * Some non gcc compile fixes with structure initialization. Changes to the Cyrus IMAP Server SINCE 2.0.3 * fixed mbpath and ipurge. Thanks to Alain Turbide for the bug report. * configure: removed mmap_private.c; it was buggy, and not worth supporting. * configure: improvements in detecting libwrap, typos fixed in detecting libsasl. * Merged the acapsieve library into libacap. * improvements to the ACAP API. * invariant checks added to the skiplist code. * bugfix in TCL cyradm. * acapmbox.c: bugfixes in handling acap connections. * fix the size given for a unix socket address (changes throughout the code), patch thanks to Vladimir Kravchenko, jimson@null.ru. * rewrote deliver to use the generic LMTP API in lmtpengine.c. Likewise, implemented the client-side API in lmtpengine.c. (Still need to implement AUTH.) * added SORT and THREAD support (Ken Murchison, ken@oceana.com.) * In checking an APPEND command, we were rejecting valid system flags and accepting invalid ones. * minor bug fixes to proxyd. * large amount of debugging code added to target-acap. * build fixes to Perl programs. * allow plaintext authentication to timsieved. Changes to the Cyrus IMAP Server in 2.0 * The mailboxes file is now a transaction-protected Berkeley database. * The core delivery process has been moved to lmtpd. deliver is now a simple wrapper to create an LMTP transaction. * master process, responsible for spawning services (imapd, lmtpd, etc.) and for routine housekeeping. Optionally, it can use libwrap to allow or deny connections. * ACAP (Application Configuration Access Protocol) support for Cyrus Murder: IMAP Aggregator. * Sieve enhancements: regular expressions, notifications, automatically setting IMAP flags. * SNMP (Simple Network Management Protocol) support for monitoring usage (e.g. number of users logged in) as well as for instrumenting protocol usage (e.g. number of times CREATE has been called). * Perl version of cyradm contributed by Brandon Allbery (allbery@ece.cmu.edu). Eventually we expect to transition to the Perl version away from the TCL version. * Bugfix in modified UTF-7 processing (for mailbox names). Bugfix in index_searchcacheheader(). * Implemented the extension MULTIAPPEND. * RENAME is now hierarchical. * The right that controls whether a mailbox may be deleted is now "c". (It used to be "d".) * An additional backend for seen state has been created, seen_db. It stores seen state in a per-user database.
