[dovecot] Benchmarks
by Timo Sirainen 10 Oct '02

10 Oct '02

Just tried Dovecot with 85k mails from Linux kernel mailing list, total of 357MB. I mostly wanted to see if the new binary tree file works well. And it does :) Nothing gets slowed down after deleting messages all around the mailbox. I tried several things with Dovecot, UW-IMAPd and Courier. You'll see that Dovecot is faster in everything else except raw I/O which is a bit strange, have to look why. I think the most important thing anyway is the time spent opening mailbox. Clients are doing "STATUS mailbox (UNSEEN)" very often and that has to be fast. With Dovecot it's so small that I didn't even bother adding it to the benchmarks, with UW-IMAPd it's 16 seconds, with courier 2 seconds. Full results can be found at http://dovecot.procontrol.fi/dovecot-benchmark.txt

[dovecot] 0.98.4 released
by Timo Sirainen 06 Oct '02

06 Oct '02

v0.99 will be next, having the new great binary tree code which should make huge mailboxes possible. With smaller mailboxes I think it still makes it better than the old code, even while it is slower in some cases (hash lookups are faster than btree search in optimal cases). v0.98.4 2002-10-06 Timo Sirainen <tss(a)iki.fi> * Just a final release before replacing hash file with a binary tree. - When fetching messages larger than 256k, sometimes Dovecot missed to send CR causing corrupted data at end of message and possibly complete failure depending on IMAP client. - Fetching BODY or BODYSTRUCTURE for message having content-type of message/rfc822 didn't correctly add () around the envelope data. - Several fixes to make it compile with HP/UX ANSI C compiler. Also fixed several warnings it showed up.

v0.98.3 2002-10-01 Timo Sirainen <tss(a)iki.fi> * Sorry, just noticed a very stupid bug which caused evolution 1.2 beta to crash. I always thought it was just evolution's fault :) - Several fields in BODY / BODYSTRUCTURE replies weren't quoted

[dovecot] 0.98.2 released
by Timo Sirainen 30 Sep '02

30 Sep '02

Lets see if I fixed all the nasty bugs now. v0.98.2 2002-09-30 Timo Sirainen <tss(a)iki.fi> + --with-file-offset-size=32 can now be used to select 32bit file offsets. Using them should be a bit faster and take a bit less disk and memory (also needed to compile Dovecot successfully with TinyCC). + maildir_copy_with_hardlinks option works now + Check new mail and notify about it to client also after commands which don't allow full syncing (FETCH, STORE, SEARCH). Also always send RECENT after EXISTS notify. + If we're out of disk space while opening mailbox, notify about it with ALERT. - STORE and SEARCH didn't handle properly message sequence numbers when some in the middle were externally deleted - SEARCH: Only first search condition was checked. - mbox: Message flags given to APPEND were ignored. - mbox: index was corrupted when changing flags for multipart MIME messages - Out of disk space-handling wasn't working properly with .customflags file - if auth processes were killed, login processes weren't reconnecting to them

[dovecot] 0.98.1 released
by Timo Sirainen 24 Sep '02

Guess I should have waited one more day before releasing 0.98 :) This fixes a few mbox problems and should finally make it safe to use. Also fixes a bug of not allowing to save mail larger than 8kB.

[dovecot] 0.98 released
by Timo Sirainen 23 Sep '02

23 Sep '02

0.98 released. This release includes LOTS of bugfixes after almost 4 weeks of actual use. We've mostly tested with Outlook 2000, Outlook Express 6 and Evolution 1.0.8. I haven't heard of a single bug in maildir for several days, and mbox worked quite well first time today :) New features include vpopmail authentication, ability to run properly when there's no disk space left to allow user to delete mail, and full support for mbox. v0.98 2002-09-23 Timo Sirainen <tss(a)iki.fi> + mbox support is finally working. There's still some reliability fixes left but overall it should be quite usable. + vpopmail authentication support + We should be able to deal with "out of diskspace/quota" conditions properly, by keeping the indexes in memory and allowing user to delete mails to get more space. + Several speed enhancements + New configuration file option: overwrite_incompatible_index to force using ".imap.index" file, overwriting it if it isn't compatible - Handle invalid message headers reliably - Tons of bugfixes and code cleanups everywhere

[dovecot] vpopmail authentication
by Timo Sirainen 20 Sep '02

20 Sep '02

CVS has now support for vpopmail authentication. .c file compiles, but I'm not sure if I did the other checks properly and if it actually works :) If someone here is using it, could you test it? At least to see if configure detects it and if it compiles/links. BTW. I think maildir support is now working quite well, 0.98 isn't far away.

[dovecot] v0.97 released
by Timo Sirainen 29 Aug '02

29 Aug '02

This is a major cleanup release. My near future goal is to make it impossible to crash Dovecot no matter what you did. This release also adds support for files larger than 2GB with Linux and Solaris. Also mbox support seems to work quite well now, except EXPUNGE and STORE are still not implemented. The "impossible to crash" should already be quite true, at least when it comes to index files. You can try to corrupt indexes in any way you want, and Dovecot should not crash. There's one exception to this: modifying the files while dovecot is reading them may crash it, this is too difficult to fix as long as shared memory maps are used, and I don't see much point in it anyway. I mostly want dovecot to survive corrupted files, not intentional crashing :) This release is the first I'd almost like to call beta-quality. But not quite. It still lacks testing and several features, but it's very close :) Changelog: v0.97 2002-08-29 Timo Sirainen <tss(a)iki.fi> + Large mails are handled in 256kB blocks, so mail size no longer has hardly any effect on memory usage + 64bit file offsets are used if supported by system. This means Dovecot is fully capable of handling >2G mails in those systems. With 32bit offsets >2G mails may not behave too well, but should not crash either. + I fixed lots of potential integer overflows. This should make us fully crash-free no matter what happens (index file corruption mostly). I didn't verify everything too carefully yet, so more auditing is still needed before we fully reach that goal. + Implemented several missing tasks / optimizations to index handling. It should now stay fast after longer usage periods. + New configuration file options: log_path, log_timestamp, imaps_listen + "Critical errors" are now hidden from users, ie. any error message that is not a direct reply to user error is written into log file and user gets only "Internal error [timestamp]". + Nonblocking SSL handshaking + Lots of code cleanups - Lots of mbox fixes, it seems to be somewhat reliable now - Year in Date-field was parsed wrong - Appending mail to mbox didn't work right - Always verify that mailbox names are valid (especially they shouldn't contain "../")
