NetworkManager r3663 - in trunk: . marshallers system-settings/plugins/ifcfg-fedora

Author: dcbw
Date: Tue May 13 16:53:50 2008
New Revision: 3663
URL: http://svn.gnome.org/viewvc/NetworkManager?rev=3663&view=rev

Log:
2008-05-13  Dan Williams  <dcbw redhat com>

	* marshallers/nm-marshal.list
		- Add VOID:POINTER,STRING marshaller for ifcfg-fedora plugin

	* system-settings/plugins/ifcfg-fedora/Makefile.am
	  system-settings/plugins/ifcfg-fedora/nm-inotify-helper.c
	  system-settings/plugins/ifcfg-fedora/nm-inotify-helper.h
		- Implement a minimal inotify helper for watch paths for IN_CLOSE_WRITE
			events.  Solely for use watching ifcfg files to pick up changes
			to their hardlinks, since GIO doesn't support this yet (bgo #532815)

	* system-settings/plugins/ifcfg-fedora/nm-ifcfg-connection.c
		- (nm_ifcfg_connection_class_init): new 'ifcfg-changed' signal when the
			file contents change
		- (finalize): clean up inotify watches
		- (nm_ifcfg_connection_new): store keyfile; inotify watch the keyfile
			and the connection ifcfg for changes on their hardlinks
		- (files_changed_cb): proxy the changed signal back out to listeners

	* system-settings/plugins/ifcfg-fedora/plugin.c
		- (dir_changed): 
		- (connection_ifcfg_changed): re-read the connection when the ifcfg
			changes
		- (read_one_connection): connect to change signals on the new connection
		- (dir_changed, connection_changed_handler,
		   handle_connection_remove_or_new): break out connection change
			handling and connection new/remove handling so it can be used from
			both the GFileMonitor callback and the NMIfcfgConnection changed
			signals

	* system-settings/plugins/ifcfg-fedora/reader.c
	  system-settings/plugins/ifcfg-fedora/reader.h
		- (connection_from_file): return the keyfile path the connection would use
