GFileMonitor: Add kqueue(3) support to GIO Written by Dmitry Matveev as part of GSoC 2011: http://netbsd-soc.sourceforge.net/projects/kqueue4gio/ This brings native file monitoring support on systems supporting kqueue(3) (all BSDs) and remove the need to rely on the unmaintained gamin software. The backend adds GKqueueDirectoryMonitor and GKqueueFileMonitor. Some parts rewritten by myself (to prevent needing a configuration file). Helpful inputs from Colin Walters and Simon McVittie. https://bugzilla.gnome.org/show_bug.cgi?id=679793

kqueue backend: port to new GLocalFileMonitor API This is the bare minimal effort. This seems not to crash immediately, but it definitely needs some better testing. The backend is not in good shape. It could use some serious work.

kqueue: Multiple fixes and simplifications - Stop using a custom thread for listening to kqueue(2) events. Instead call kevent(2) in non blocking mode in a monitor callback. Under the hood poll(2) is used to figure out if new events are available. - Do not use a socketpair with a custom protocol requiring 2 supplementary context switches per event to commicate between multiple threads. Calling kevent(2), in non blocking mode, to add/remove events is fine from any context. - Add kqueue(2) events without the EV_ONESHOT flag. This removes a race where some notifications were lost because events had to be re-added for every new notification. - Get rid of the global hash table and its associated lock and races. Use the 'cookie' argument of kevent(2) to pass the associated descriptor when registering an event. - Fix _kh_file_appeared_cb() by properly passing a monitor instead of a source to g_file_monitor_emit_event(). - Properly refcount sources. - Remove a lot of abstraction making it harder to fix the remaining issues. https://bugzilla.gnome.org/show_bug.cgi?id=739424

kqueue: Make it possible to pass file monitor tests Previously, kqueue file monitor only add event sources for directories regardless of the type of the file being monitored. Doing so may be possible on inotify, but it is not sufficient on kqueue. Watching a directory on kqueue doesn't report changes made to files under it, and we must watch files themselves to get notified. This problem is fixed by adding a second watch for non-directory file monitors, and the result is that we are now able to receive 'CHANGED' and 'ATTRIBUTE_CHANGED' events for non-directory files. Since having two watches on one file monitor requires many code changes to work properly, this commit also changes the following things: - NOTE_ALL macro is now replaced by note_all inline function. Since the kqueue backend is shared by all BSD operating systems, there are a few difference between these systems. It is easier to do '#ifdef' check in a function than in a macro. - Both g_kqueue_file_monitor_callback and g_kqueue_file_monitor_cancel now holds a lock before accessing kqueue_sub structs. This fixes a crash when these two functions are called from different threads, causing g_kqueue_file_monitor_callback to access freed memory. - 'mask' variable in g_kqueue_file_monitor_callback is now removed. The usage of 'mask' was wrong because of the 'mask > 0' check. 'CHANGED' event has value 0 so the 'mask > 0' check made it impossible to emit 'CHANGED' events. - kqueue-missing scans can now be triggered from the kqueue event callback instead of always waiting for 4 seconds. - Don't remove a file from kqueue on unlink unless its hard link count has dropped to zero. - Don't use 'else if' in the check of 'fflags'. It is possible for a kevent to have multiple flags set. - Don't use g_file_monitor_emit_event directly. Always use g_file_monitor_source_handle_event to report events. Events submitted to g_file_monitor_emit_event are delivered immediately, but events sent to g_file_monitor_source_handle_event are scheduled by GLocalFileMonitor. If we mix the two, the order of events will be wrong and tests will fail. - Report 'CHANGES_DONE_HINT' immediately after 'CREATED' if the file created is not a regular file. This is copied from ih_event_callback.
