Hi Keith, Thanks for directing me to the example code. As i see the code, one thing that i can understand is that the application is doing add and connect to the signal. What will actually trigger DBUS to send the signal to the application. What i mean to say is that how from an application can i send signals to other application with DBUS working as a mediator for passing signals.( as i can see no such calls in this code atleast) It will be of great help if you could help me with sorting it out. Thanks in advance.

It is maintained, though currently only by me! One issue is I'm not set as the default maintainer in the bugzilla.. (/me pokes fd.o maints) I don't have a whole load of time to dedicate to it. If you look at <a href="http://gitweb.freedesktop.org/?p=dbus/dbus-glib.git;a=summary">http://gitweb.freedesktop.org/?p=dbus/dbus-glib.git;a=summary </a> you can see what's been done towards a 0.72 release - currently on my TODO is add tests for the GInterfaces/GObject inheritance stuff by Steve Frécinaux, and to remove the need for a system bus at build time. If you want to help out with bug triaging and testing fixes (ideally there should be a unit test testing each fix, where possible), I'd be very grateful for a helping hand!

Maybe using some meta-object magic? You can easily export slots, signals and properties of any given QObject. So, I recommend that you use that method of construction: create your own hierarchy of QObject with the exportable methods. [Hint: making them Q_SCRIPTABLE and using the ExportScriptableSlots flag makes it easy to distinguish which slots are meant to be exported.] Note, however, that there are some limitations on what you can hide from: the QtDBus demarshaller works in a lazy mode, which means that any complex that is not integer, double, QString, QByteArray or QStringList (or a QVariant containing any of those) will not be decoded until much later. This means it requires some help from the application code itself to do the decoding -- especially in the case of QVariants. If you don't need any other type, you should be reasonably safe, though. (Just don't ever try to access QObject::sender()) -- Thiago Macieira - thiago (AT) <a href="http://macieira.info">macieira.info</a> - thiago (AT) <a href="http://kde.org">kde.org</a>   PGP/GPG: 0x6EF45358; fingerprint:   E067 918B B660 DBD1 105C 966C 33F5 F005 6EF4 5358 -------------- next part -------------- A non-text attachment was scrubbed...

Not even talking about debian & friends... No one is adding value by making things incompatible, and it's real burden for application developer.

This enables us to fork off the activation helper early and keep it running as root, thus being able to make activation on the system message bus useful. Details - Move some test harness around - BusContext now requires a function to clean up - The bus process and the helper process communicate over a pair    of pipes. I specifically avoided using D-Bus as the IPC because    if the bus process is compromised the likely way it is compromised    is by libdbus being compromised. The protocol is very custom and    simple. Should be feasible to do security audits on it. - Helper process is written with paranoia in mind - it does not trust    the bus process - There's a new 'User' key that can be set in service files to specify    what user to run the activated service as TODO's - What should we do if 'User' key is not set for system bus activation?    Just run it as root? - Conversely, what to do if 'User' key is set for session bus    activation? Just refuse to run it? - The test suite fails, says OOM handling doesn't work. I'm looking at    this, I think I'm doing the wrong thing if a BusTransactions fails,    should be feasible to fix (any quick ideas what I'm doing wrong?)    Apart from OOM handling the test suite works and this is good as the    test suite exercises a lot of the activation subsystem. - Not sure how to do OOM tests for helper since it's a separate    process, ideas welcome - Not sure how add meaningful tests to activation-helper.c, ideas    welcome too - Some general cleanups and removing some noise I've introduced in    places. Anyway, I think the patch is in a state and I'd like feedback on the approach and details too.
