v1.1 plans have changed a bit. I'll release v1.1.alpha1 soon and hope to have a stable v1.1 in a month or two. The rest of the features that didn't make it into v1.1 will go to v1.2. I'll write more about this when v1.1 alpha is released. I also did a bit of benchmarking. v1.1's performance improvements are looking pretty great, it seems to be twice as fast as v1.0. v1.0:

The biggest problem with getting v1.0 out was getting its index file code stable. v1.1 plans included doing large changes to the index file code, so it's important to get the new code stable as soon as possible. Since I've managed to stay pretty productive for the last few weeks, I've been mostly just coding the index changes. Once I'm sure that the code is again fully working

I just changed Dovecot v1.1 code to work much more nicely when appending new messages to large mailboxes. Dovecot hg (cydir format, fsync_disable=yes): ./imaptest secs=1 ./imaptest - append=100,0 logout=0 msgs=10000000 clients=1 seed=1 secs=300 Logi Sele Appe 100% 100% 100% 1 1 2322 1/ 1 0 0 1998 1/ 1 0 0 2293 1/ 1 0 0 2009 1/ 1 0 0 1789 1/ 1 0

I spent the last 5 hours or so updating my imaptest tool. It's beginning to become almost like a real IMAP client. http://dovecot.org/tools/imaptest10.c contains a version that compiles against Dovecot v1.0 (instead of against CVS HEAD). imaptest is this tool that I've been using for a few years to do stress testing. It can create a lot of dummy IMAP client connections which execute some

http://dovecot.org/tools/imaptest.c now keeps track of messages' metadata and complains if they change. It relies on Message-ID: header being unique in the source mailbox, otherwise it'll give bogus errors. I might fix that some day. I changed the code from using simple line-based parsing to Dovecot's imap-parser code. Unfortunately it looks like it's pretty slow. At least I'm

I have a situation with many users and an existing mail delivery agent. Seems like I once saw an imaptest program which I imagine might be used to pre-index maildirs. For example... - remember which users and user maildirs have changed since last pre-index - when system quiet pre-index any maildirs which have had mail delivered and no access by a mail client (using some

Some new features in CVS HEAD are: - v1.0 saves most of the data to dovecot.index.cache only when the client is FETCHing the messages. With mboxes the message headers are saved while parsing the mbox, which is almost the same thing. With CVS HEAD the dovecot.index.cache file is updated already when the new messages are being saved (with deliver or IMAP APPEND). This avoids reading the message

I fixed the nightly snapshot building. Now it's again being built every night (if there have been any changes). Please test it before I'll make rc18 release. http://dovecot.org/nightly/dovecot-latest.tar.gz I've also been stress testing a lot with http://dovecot.org/tools/imaptest.c. Last night I ran it for 9 hours with mmap_disable=yes and it picked up only one race condition, which
