End of a book : Johnny in Novell

with 13 comments

Last day in Novell.

Started out as an intern in the GNOME team about 5 years back. Jumped between Evolution and iFolder a few times for different (voluntary/involuntary) reasons. Met a lot of good engineers. Had both good / bad times. Learned a lot work / non-work.


I loved working on Evolution, Evolution MAPI (may not be perfect, but had a awesome time with it And i’m yet to cash in on the few beers i’ve been offered), Attachment Reminder (Trivial, but looks like you guys liked/hated/loved it), Redesign of Evolution search bar and so on. Best bug that I’ve worked on so far was changing a ‘1’ to ‘-1’ in EText (Oh those early days! Had no clue what GDB can do.. Used hundreds of ‘printf’s, lots of coffee and tested the patience of office night guards and that adrenalin rush!). Thanks to Novell for the opportunity to contribute full-time and getting paid for that.

Special thanks to my mentor Srini. I’m looking forward for more new awesome fun things in GNOME.


I’ll miss the 1-1 coffee breaks talking games/gadgets/music, discussions on research papers that I don’t have a clue about, conversations during ‘tea breaks’ outside office (you would see me very inspired/productive after those sessions), thursday nights 😉 & nice friends that I found beyond ‘work’.

The End.

Push Email for GNOME Evolution’s Exchange MAPI provider (exchange 2007)

with 13 comments


After few days of crazy bug hunting (and creating the same) , we have a nice push event notification framework for Evolution-MAPI. When Evolution is running all the changes happening in user’s mailbox in server would immediately be synced. This avoids those long fetches from server.  A short screen cast (watch in HD) :
Currently I’ve got “new mail” event handled and is limited to mailer. Would be working on other events. This feature has some major issues to be solved before it can land in master.
It is FUN !

Evolution MAPI : Contributions… Testing… Bugzilla …

with 2 comments

Development is more active after our move to new svn ! Julien (of has patched evolution-mapi to be compatible with libmapi 0.8 .Patches are welcome 🙂 !

Some of the cool things with libmapi 0.8 is the possibility of having multiple exchange accounts (multiple sessions) in Evolution (Yep. you read that right! ). But they will hit the trunk little later .

Now more focus is on real world testing on servers other than few test servers we are running. What doesn’t work in different setups is something we would like to know and fix them all ! Thanks to those who have been reporting issues and TIA 🙂


+ evolution-mapi is proposed for GNOME 2.26. Yay !

+ we have a new product ‘evolution-mapi’ in GNOME bugzilla.

+ Wiki page is updated with information on building evolution-mapi .

Evolution Exchange 2007 (MAPI) Provider : Changes in schedule and more.

with 2 comments

Code :

We have moved away from libmapi 0.7 to libmapi trunk (0.8 development) , so we can take advantage of the new APIs.

We will be constantly updating our code base to libmapi trunk.

Currently :

Suman is busy in integrating meetings into evolution. (few more tasks left)

I’m currently working on finishing (completing) off the basic features in mailer and will move to optimizing the sync & more.

Schedules :

Sadly, we won’t be able to make it to Evolution 2.24 as we are late (details here). 😦 Meanwhile we will continue to provide pluggable packages and this will be available as a pluggable provider. 2.26 will have this.

Licensing :

Yay ! Very exciting day. Evolution licence change was announced by Michael Meeks in my talk this morning (Exchange, MAPI and Evolution) . Announce mail here!! .

Update 1 : GUADEC Talk available here

Committed *initial* python eplugin loader for Evolution. Please feel free to fix it 🙂 .

Bindings yet to be done (without which it is not useful) . I’m looking (doing some initial work) at pygtk-codegen for generating the required bindings.
