There are no actual statistics yet, just a count of how many times the method has been called, and (for the per-connection stats) the unique name. Bug: https://bugs.freedesktop.org/show_bug.cgi?id=34040

2011-03-01match_rule_to_string: don't reinvent dbus_message_type_to_stringSimon McVittie1-30/+3
We don't allow match rules with unknown message types, so losing the "type='%d'" case isn't a great loss.
2011-02-25dbus_connection_dispatch: avoid freeing UnknownMethod reply until we unlockSimon McVittie1-4/+16
Bug: https://bugs.freedesktop.org/show_bug.cgi?id=34393
2011-02-25_dbus_connection_peer_filter_unlocked_no_update: delay freeing replySimon McVittie1-41/+40
Finalizing the reply could conceivably call callbacks, so wait til we unlock. Bug: https://bugs.freedesktop.org/show_bug.cgi?id=34393
2011-02-25Don't finalize sent or dispatched messages while under the connection lockSimon McVittie2-13/+62
Finalizing a message can trigger callbacks; that's bad, if we have a connection locked. In particular, if a message is received by the "left side", passed to the "right side" and sent (as in test/relay.c (see the diagram there) or in dbus-daemon), then finalizing that message could result in the live messages counter for the left side, and the outgoing messages counter for the right side, both being decremented while under either side's lock. After a message is dispatched on the left side, finalizing it now drops the lock temporarily, to avoid this problem. After a message is sent on the right side, finalizing it is now deferred until the right side unlocks, by moving it to a new queue of "expired messages" which is automatically cleared every time we release the lock. The "live messages" counter for the "left" connection will now explicitly take the left connection's lock before decrementing, to avoid manipulating watches without a lock. Bug: https://bugs.freedesktop.org/show_bug.cgi?id=34393
2011-02-25Don't inline the contents of _dbus_connection_unlockSimon McVittie1-6/+8
It's about to become more complex, to handle delayed deallocation of messages in order to avoid triggering callbacks while locked.
2011-02-25When attaching counters to messages, don't automatically notify callbacksSimon McVittie3-3/+23
In all the places where counters are added, we're under a lock. The caller knows what effect adding the counter might have, and can replicate it in a lock-safe way if necessary. Bug: https://bugs.freedesktop.org/show_bug.cgi?id=34393
2011-02-25Comment some places where it's OK to unref a message despite holding locksSimon McVittie2-0/+4
In general, dbus_message_unref should be avoided while holding locks, because it can invoke arbitrary user callbacks (via attached data, or via DBusCounter).
2011-02-25Add _dbus_counter_notify and call it after every adjustmentSimon McVittie3-6/+34
When fd-passing is implemented, adjustments happen in pairs; in that case we coalesce the two calls into one.
2011-02-25_dbus_connection_message_sent: rename to _unlockedSimon McVittie3-6/+6
It's called with the connection's lock held.
2011-02-25dbus_bus_register: don't unref the messages with the lock heldSimon McVittie1-12/+11
Finalizing a message can call out to user code via dbus_message_set_data (or to internal code not expecting locks to be held, via DBusCounter).
2011-02-25Add a hackish script to reproduce fd.o #34393Simon McVittie6-1/+68
The number of messages is arbitrary; the more messages, the more likely the crash is. 2000 messages seem to cause it reliably, on this laptop. The script may have race conditions (there are a couple of hard-coded sleep calls), so I haven't set it up to be run automatically.

2011-02-24Allow X11 autolaunch to be disabled even if the headers/libraries are thereSimon McVittie4-22/+47
In an embedded system where the D-Bus session is a core part of the environment, like Maemo, accidentally auto-launching a second session bus (for instance for a concurrent ssh session) is a bad idea - it can lead to a "split brain" situation where half the applications in the GUI are using a different bus. In these controlled environments, it'd be useful to prevent autolaunch from ever happening. (As a side benefit, the changes to configure.in also mean that packagers can explicitly --enable-x11-autolaunch, to make sure that failure to find X will make compilation fail cleanly.)

2011-02-24Give XDG_DATA_HOME priority over XDG_DATA_DIRS for servicedirsSimon McVittie1-23/+26
According to the XDG Base Directory Specification, “the base directory defined by $XDG_DATA_HOME is considered more important than any of the base directories defined by $XDG_DATA_DIRS.” This makes it easier to override a system service file as a normal user.
