* 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).

* And move the sending of other types of D-Bus messages to the threadThiago Macieira2015-09-151-1/+1
| | | | | | | | | | With this, we now know that all messages sent are sent from the same thread. This simplifies greatly the handling of the socket.

* Implement the blocking QtDBus call in terms of the non-blocking oneThiago Macieira2015-09-151-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This simplifies the code a little by having a single code path. More importantly, we no longer need to call the evil function dbus_connection_send_with_reply_and_block. That function acquires a lock on the socket transport inside libdbus-1, which means all threads need to wait until the one call gets unblocked before they can continue. To do that, this commit reimplements the QDBus::Block part of QDBusConnectionPrivate::sendWithReply by reusing the existing call to sendWithReplyAsync() and then doing a blocking-wait with QDBusPendingCallPrivate::waitForFinished(). By using (Q)DBusPendingCall and the threaded connection approach (next commit), now we never block on the socket. That also means the code to call dbus_pending_call_block() is no longer necessary and the waitForFinished() function itself can be considerably simplified. As a side-effect of no longer blocking, a number of pre-existing race conditions that used to be hidden showed up. Note: this commit deadlocks without the threading (next commits).

* Update copyright headersJani Heikkinen2015-02-111-7/+7
| | | | | | | | | | | | | | | | | | Qt copyrights are now in The Qt Company, so we could update the source code headers accordingly. In the same go we should also fix the links to point to qt.io. Outdated header.LGPL removed (use header.LGPL21 instead) Old header.LGPL3 renamed to header.LGPL3-COMM to match actual licensing combination. New header.LGPL-COMM taken in the use file which were using old header.LGPL3 (src/plugins/platforms/android/extract.cpp) Added new header.LGPL3 containing Commercial + LGPLv3 + GPLv2 license combination Change-Id: I6f49b819a8a20cc4f88b794a8f6726d975e8ffbe Reviewed-by: Matti Paaso <matti.paaso@theqtcompany.com>

| * QDBusConnection: Merge the dispatch and the watch-and-timeout locksThiago Macieira2014-11-051-7/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We don't need two anymore because they now protect the same thing: the state of the DBusConnection. The difference existed when it was possible for two threads to access the DBusConnection at the same time: one doing dispatching and one doing something else. Unfortunately, even though DBusConnection supports this, QtDBus doesn't. From d47c05b1889bb4f06203bbc65f4660b8d0128954 (2008-10-08): Details: if we're removing a timer or a watcher from our list, there's a race condition: one thread (not the QDBusConnection thread) could be asking for the removal (which causes an event to be sent), then deletes the pointer. In the meantime, QDBusConnection will process the timers and socket notifiers and could end up calling lidbus-1 with deleted pointers. That commit fixed the race condition but introduced a deadlock.

| * Always lock the DBus dispatcher before dbus_connection_send*Thiago Macieira2014-11-051-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We lock it before dbus_connection_send_with_reply (the async version) in QDBusConnectionPrivate::sendWithReplyAsync. We weren't locking it before send_with_reply_and_block and we apparently should. The locking around the dbus_connection_send function might not be necessary, but let's do it to be safe. The lock now needs to be recursive because we may be inside QDBusConnectionPrivate::doDispatch.
