[SOGo] Upcoming Improvements

  • Date: Wed, 27 Jul 2011 13:53:35 -0400
  • Organization: Inverse inc.

Hi,

Just a quick status on two things.

First, we'll release again a new version of our OpenChange backend this week. This will feature major improvements regarding the handling of "version numbers" for messages, tons of bug fixes and many speed improvements. For example, we implemented QRESYNC support for IMAP in order to quickly synchronize changes that happened on IMAP mailboxes.

Secondly, we've been working on the past few weeks on porting PyObjC (http://pyobjc.sourceforge.net/) to GNUstep. Things are now starting to work quite well with the GNUstep runtime (libobjc2-1.5) and the gcc runtimes (< 4.6 and >= 4.6). This will allow people to script and extend SOGo in Python - without much knowledge of the innards of SOGo and more importantly, without recompiling anything.

This will likely be integrated in the next big release, together with some initial hooks.

I've attached the latest patch to PyObjC to this email, in case some of you want to toy around with it and help us improve it.

As usual, feedback is welcome.
