Quite so. We're currently most of the way through an (unfortunate) rewrite to fix some database-related problems. IMAP4 hasn't been high on the port-list, so there's no IMAP4 code in the new codebase yet. However, Twisted's IMAP4 protocol implementation was developed for this project, and IMAP4 is on our mind as we implement things, so adding it isn't going to be obstructed by anything in Quotient (I would say "easy" but nothing related to IMAP4 is easy). > >Seems like I'd spend more time understanding the framework system >you're using than it would take me to write it from scratch. Ahhh, I doubt it. This isn't to say you wouldn't spend a while understanding the framework, but writing it from scratch would take longer. >An IMAP server isn't hard. Having spent fair chunks of the last several years implementing various IMAP4 servers, I must disagree. :) Unless you're happy with a semi-protocol spec, semi-broken server that doesn't scale to a decent number of messages, it's quite a haul. >And I don't think the project is all that equivalent. Strictly speaking, an IMAP4 server will be a subset of Quotient, and IMAP4 is by no means the main focus of Quotient, so maybe equivalent wasn't the right word. > >Does Twisted support the use of PyLucene?

It's possible you'd be happier basing the IMAP4 server on Twisted's protocol support, rather than starting from Quotient (although _I'd_ be happier if you added IMAP4 support to Quotient ;). Quotient uses a SQLite database for storage of structured data about messages and a filesystem structure (currently not a great structure, but it's fixable) for actual message files. It supports per-user filtering rules (although not procmail based - and the work done in this area so far is extremely minimal, basically it can do substring matching on headers - expanding this would be pretty simple though, Quotient is designed for this kind of thing). The SMTP server can be turned off completely, although then you need another mechanism for adding messages to the system (inotify + directory would work, but you'll have to write that part). For users, the web interface is optional too, but various admin tasks may continue to require some web interaction. > >If DivmodQuotient is anywhere close to that, I'll take a longer look. It sounds like you might be happier starting from Twisted's IMAP4 code rather than doing the work in Quotient, unless your requirements are somewhat more flexible than I have gotten the impression that they are. I _certainly_ would not recommend doing the protocol implementation from scratch. Using Twisted there at least is a complete win. As for PyLucene in that scenario, there's no _direct_ support for gcj threads in Twisted. All of my work with PyLucene in Quotient has been in the main thread in a child process of the main process (desirable to avoid segfaulting the main server, mainly). Note (in case it isn't obvious yet) I'm a developer on both Quotient and Twisted, and I wrote pretty much all of Twisted's IMAP4 code. It's possible I'm slightly biased. That said, lots of people have told me Twisted's IMAP4 implementation is the best they've worked with, that it saved their thesis, project, company, life, etc. ;) Jean-Paul _______________________________________________ Web-SIG mailing list Web-SIG@python.org Web SIG: http://www.python.org/sigs/web-sig Unsubscribe: http://mail.python.org/mailman/options/web-sig/archive%40mail-archive.com
