| * DBus: fix deadlock when destroying QDBusServerMårten Nordheim2019-08-161-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Observed infrequently in the QDBus tests, it would deadlock when destroying QDBusServer at the same time as qDBusNewConnection was being executed as they were locking the same locks, but in opposite order. QDBusServer locks d->lock, then QDBusConnectionManager::instance()->mutex. While qDBusNewConnection locks QDBusConnectionManager::instance()->mutex, then serverConnection->lock (and serverConnection here is QDBusServer's d-pointer). QOrderedMutexLocker cannot be used in this situation because it operates on QMutex*, which d->lock (QReadWriteLock) is not. Change the code to lock QDBusConnectionManager's mutex before d->lock and then unlock the QMutexLocker where it would previously destruct. If QDBusConnectionManager has already been destroyed then we pass a nullptr to the QMutexLocker which is fine and will not do anything.

* Use a dedicated thread for handling incoming libdbus-1 eventsThiago Macieira2015-09-151-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Fix undefined behavior: accessing an object after destructionThiago Macieira2015-04-151-0/+1
| | | | | | | | | | | | | | | | | | QDBusConnectionPrivate keeps a pointer to a QDBusConnectionInterface, which in turn holds a reference back to that QDBusConnectionPrivate. During the interface object's destruction, the QDBusAbstractInterface's destructor checks if the interface is still valid. That access is undefined behavior, but has so far been benign in all our uses since the memory had not yet been freed (just destroyed) and the reference count went from 0 to -1. To be on the safe side, we destroy now the QDBusConnectionInterface object while the Private is still valid. It will bring the reference count down from 0 to a negative number, but won't cause any other effects.

* Remove the hardcoding of Unix socket paths for QtDBusThiago Macieira2014-12-201-3/+9
| | | | | | | | | | | | | | | | | | | This allows the tests to be run on Windows too by using TCP socket connections instead of requiring Unix sockets. The tests shouldn't have hardcoded the path, which came from QDBusServer anyway. Now the tests simply defer to QDBusServer. This is a slight behavior change for Windows, but not one that should matter since anyone who was using the default constructor resulted in a QDBusServer that failed to listen. [ChangeLog][QtDBus][QDBusServer] Fixed a bug that made QDBusServer's default constructor try to bind to a Unix socket on non-Unix systems. Now QDBusServer will attempt to bind to a TCP socket instead.

| | | | | | | | | | | | | | | | | | | Commit 5be6cf0a6e306ed3a51ed5ba89317b1317544eea introduced an implicit cast from const char* to QString in QDBusServer's constructor, which breaks the compilation of applications which use QtDBus when QT_NO_CAST_FROM_ASCII is defined and clang is used. Fix it by splitting the current constructor with the broken default argument into one which takes a non-default QString and one which only takes a QObject* parent and calls the other with the current default argument. It would have been better not to have mostly duplicate code in both constructors, but QDBusConnectionPrivate is also used in other places.
