2003-02-15 Alexander Larsson <alexl@redhat.com> * dbus/dbus-threads.c: * dbus/dbus-threads.h: Add condvars. Remove static mutext from API. Implement static mutexes by initializing them from threads_init. * glib/dbus-gthread.c: * qt/dbus-qthread.cpp: Update with the thread api changes. * dbus/dbus-list.c: * dbus/dbus-list.h: Turn StaticMutex into normal mutex + init function. Export new functions _dbus_list_alloc_link, _dbus_list_free_link, _dbus_list_append_link, _dbus_list_prepend_link * dbus/dbus-sysdeps.c: * dbus/dbus-sysdeps.h: New type dbus_atomic_t, and new functions _dbus_atomic_inc, _dbus_atomic_dec. Only slow fallback implementation at the moment. * dbus/dbus-protocol.h: Add DBUS_MESSAGE_LOCAL_DISCONNECT define * dbus/dbus-message.c: Make ref/unref atomic. Fix some docs. * dbus/dbus-connection-internal.h: * dbus/dbus-connection.c: * dbus/dbus-connection.h: Make threadsafe. Change _peek to _borrow,_return & _steal_borrowed. Change disconnect callback to event. Make dbus_connection_dispatch_messages reentrant. * dbus/dbus-transport.c: Don't ref the connection on calls to the transport implementation. * dbus/dbus-message-handler.c: Make threadsafe. * glib/dbus-gmain.c: Don't use peek_message anymore * test/Makefile.am: * test/debug-thread.c: * test/debug-thread.h: Simple thread implementation that asserts() on deadlocks in single-threaded code. * test/bus-test.c: (main) Call debug_threads_init. * test/watch.c: Use disconnect message instead of disconnect callback. * bus/connection.c: * bus/connection.h: Don't call dbus_connection_set_disconnect_function. Instead export bus_connection_disconnect. * bus/dispatch.c: Call bus_connection_disconnect when we get a disconnected message.
