Playing with DBus - 2
March 23rd, 2007
Some more DBus poking…
Listing the interfaces available in session (or system)
#> dbus-send –session –type=method_call –print-reply –dest=org.freedesktop.DBus /org/freedesktop/DBus org.freedesktop.DBus.ListNames
method return sender=org.freedesktop.DBus -> dest=:1.49
[string “org.freedesktop.DBus”
string “:1.49″
string “:1.3″
string “org.gnome.PowerManager”
string “org.gnome.ScreenSaver”
string “org.xchat.service”
string “:1.4″
string “:1.0″
string “:1.5″
string “:1.6″
string “:1.2″
Now lets query org.gnome.PowerManager
#> dbus-send –session –type=method_call –print-reply –dest=org.gnome.PowerManager /org/gnome/PowerManager org.freedesktop.DBus.Introspectable.Introspect
method return sender=:1.2 -> dest=:1.52
string “<!DOCTYPE node PUBLIC “-//freedesktop//DTD D-BUS Object Introspection 1.0//EN”
“http://www.freedesktop.org/standards/dbus/1.0/introspect.dtd”>
<node>
<interface name=”org.freedesktop.DBus.Introspectable”>
<method name=”Introspect”>
<arg name=”data” direction=”out” type=”s”/>
</method>
</interface>
<interface name=”org.freedesktop.DBus.Properties”>
<method name=”Get”>
<arg name=”interface” direction=”in” type=”s”/>
<arg name=”propname” direction=”in” type=”s”/>
<arg name=”value” direction=”out” type=”v”/>
</method>[SNIP]
</signal>
<signal name=”OnAcChanged”>
<arg type=”b”/>
</signal>
</interface>
</node>
“
Note : Remember to use –session when introspecting services listed with –session flag & vice-versa (–system)

Check out this listener - still incomplete in many ways…
Compile with “gcc listener.c -o listener `pkg-config –cflags –libs dbus-glib-1`” and run with “./listener” & to create a stream of events, fire up evolution & just start browsing through emails.
–> Signal received!
Signal path : /org/gnome/evolution/mail/newmail
Signal interface : org.gnome.evolution.mail.dbus.Signal
Signal name : MessageReading
Signal sender : :1.5
Payload : [Inbox]
Signal had 1 arguments in the payload

And the life moves on…
March 22nd, 2007
Today, I finally finished all the formalities at Red Hat - deposited the laptop back with IS/IT, handed over the drawer keys to Murty ji, had a long discussion with Satish in the exit interview, burnt a copy of Fedora devel tree & finally bid goodbye to all the RedHatters 
Leaving RH was a bit nostalgic - lots of good memories were associated with that office - our pune-trans team which was more of a family than a team, our no-mercy pool games, those TT matches, those awesome treks (I still remember how Bhalerao & Aalam had held me from falling down a steep slope!) & specially that night trek… I might miss that all!
I still plan to keep up with m17n-db & evolution projects - maybe when the core packages open up to general public with Fedora 7, I might apply for m17n-db’s ownership.
But till then, DBus’s on my mind - on all 360 degrees!
For those who never worked with Red Hat - an excellent company to work with, very laid back & relaxed environment, gives freedom to work on projects which you might like (ofcourse, official work needs to be finished first!)… & if you are a starter in the FLOSS arena, RH’s the best place to learn - how to interact with the comunity.
It was… & will remain a dream company for me!
PS: (I’m going to install FC here on my machine when Celunite shifts to Kumar Cerebrum & when I’ll get my permanent box). I’ll set up atleast one FC repository here

Happy B’day Rama
March 22nd, 2007
Pictures say it all… we all got together at Emilia 401 to celebrate Rama’s B’day & it was superb fun! I just hope Anna managed to put those videos (shot from Ratish’s camera) on youtube…
The birthday boy - Rama
Anna, Ravi, Satish (Behind Rama), me & Ratish
Someone had to hold Rama from running around 
Poor dude… the cake was all over him! Even the icing could not make it to our tummies…
…Just monkeying around - hahahaha
BTW, just to mention, the credit for yesterday’s party goes to Ravi - who remembered the birthday in first place & organized the cake along with Satish. Good work guys!

Lets see what future has in store for me here…
