* Add qtdbusglobal.h and qtdbusglobal_p.hLars Knoll2016-07-141-0/+1
| | | | | | | | | | | | | | The new modular configuration system requires one global header per module, that is included by all other files in this module. QtDBus already had such a header, but its name (qdbusmacros.h) was not in line with what's being used in all other modules. So add a qtdbusglobal.h header, and turn qdbusmacros.h into a a forwarding header to that new global header file.

* Suspend processing of some messages in the default busses by defaultThiago Macieira2016-01-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To retain a bit compatibility with applications developed in the last 9 years that expect that QDBusConnections won't process their events until the event loop runs, we now suspend the handling of incoming messages in the two default buses (and only in them) and resume when the event loop starts. This is required because the new threaded QtDBus would otherwise process incoming messages that the application didn't expect it to. For example, if the application first acquires names on the bus and only after that registers objects with QtDBus, there's a small window in which the name is acquired and visible to other applications, but no objects are registered yet. Calls to those objects may be received, would then be processed in the QDBusConnectionManager thread and fail. The work around is to disable the actual handling of method calls and signals in QDBusConnectionPrivate::handleMessage. Instead, those messages are queued until later. Due to the way that libdbus-1 works, outgoing method calls that are waiting for replies are not affected, since their processing does not happen in handleMessage(). [ChangeLog][Important Behavior Changes] QtDBus now uses threads to implement processing of incoming and outgoing messages. This solves a number of thread safety issues and fixes an architectural problem that would cause all processing to stop if a particular thread (usually the main thread) were blocked in any operation. On the flip side, application developers need to know that modifications to a QDBusConnection may be visible immediately on the connection, so they should be done in an order that won't allow for incomplete states to be observed (for example, first register all objects, then acquire service names).

* Merge two Q_GLOBAL_STATICS into another and solve memory leakThiago Macieira2015-09-151-0/+4
| | | | | | | | | | | | | | | | | | | | | | | The two global statics for the session and system buses aren't necessary if they can't outlive the global static for QDBusConnectionManager anyway. So merge them there. The extra mutex is necessary because the QDBusConnection::connectToBus function will lock the regular mutex. This solves a potential memory leak at exit as a side-effect. Before this change, the session and system QDBusConnection object got destroyed in the main thread during global destruction, so it had to post an event to the QDBusConnectionManager thread to finish the destruction of the private. However, QCoreApplication is already gone by this point, so the QEvent::DeferredDelete event never got delivered. After this commit, there's no global static to destroy the QDBusConnection (there is no QDBusConnection holding a reference), so the object gets destroyed in QDBusConnectionManager::run()'s cleanup code.

* And move the creation of connections to the threadThiago Macieira2015-09-151-0/+11
| | | | | | | | | | Now we know that all timers and socket notifiers get created only in the QDBusConnectionManager thread. Incidentally, this reduced code duplication. Change-Id: I27eaacb532114dd188c4ffff13d5075a8d2efb0b Reviewed-by: Alex Blasche <>
* Use a dedicated thread for handling incoming libdbus-1 eventsThiago Macieira2015-09-151-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | Each application will have one thread dedicated for this, for all QDBusConnections. I wouldn't mind sharing such a thread with other uses in Qt, provided none of them ever block (the QProcessManager thread comes to mind, but it's going away soon). The cost associated with this change in this commit is so far rather minimal. All incoming D-Bus calls need to be handled after an event is posted anyway, to avoid deadlocking on reentering libdbus-1 functions that acquire locks still held. The cost is the one more thread running and the cost of synchronizing them when an event is posted. The benefits far outweigh that cost: no longer will we have problems of QtDBus failing to run if the main system or session connections are used before QCoreApplication is run. Moreover, events can be received and handled in aux threads even if the main thread is blocked on some operation. Note: this commit may not be testable (tst_qdbusconnection may fail) Task-number: QTBUG-43585 Change-Id: Ic5d393bfd36e48a193fcffff13b737556ccd11a8 Reviewed-by: Albert Astals Cid <> Reviewed-by: Alex Blasche <>
