Description Mike Cvet 2006-08-31 14:23:43 UTC 
frysk.sys.Stat can be enhanced to read thread-specific information from the
/proc filesystem. This information can be used to display to the user which
threads have used more jiffies, memory, and other useful information.

frysk-sys/frysk/sys/proc:
2006-09-06  mcvet  <mcvet@redhat.com>

	* Stat.java (tid): Refactored from the int pid. More correct variable name.
	(refreshThread): Added - supports reading proc stat information for threads
	belonging to a process.
	* cni/Stat.cxx (refreshThread): Added. Nearly identical to refresh() but
	handles individual threads belonging to a process.
	(refresh): Updated to use new variable tid.
	* cni/slurp.cxx (slurp_thread): Added. Reads from /proc/PID/task/TID/stat.
	* cni/slurp.hxx (slurp_thread): Added header for above function.

frysk-gui/frysk/gui:
2006-09-06  mcvet  <mcvet@redhat.com>

	* glade/procpop.glade: Added the tidColumnDialog dialog window.
	* glade/processpicker.glade: Changed layout of header so that it 
	is displayed properly. 

frysk-gui/frysk/gui/monitor:
2006-09-06  mcvet  <mcvet@redhat.com>

	* TIDColumnDialog.java: Added. Almost identical to the
	PIDColumnDialog, but needed because of the extra glade reference.
	* ThreadMenu.java (ThreadMenu): Removed static reference, 
	turned into dynamic menu like ProcMenu. Added entries to deal
	with thread view customization like the process viewer.
	(getMenu): Removed.
	* StatusWidget.java (StatusWidget): Commented out some 
	unneeded mouse listeners.
	* SessionProcTreeView.java (SessionProcTreeView): Addressing #3160.
	Added new variables to handle extended thread information. Uses 
	the new dynamic ThreadMenu. Added new listeners for procPid and
	threadTidColumnDialogs.
	(mountThreadModel): Added listeners for all the new thread columns.
	(threadViewInit): Initialized and added information for all the new
	thread columns.
	(refreshProcTree): Refactored from refreshTree().
	(refreshThreadTree): Added.
	(setProcCols): Refactored from setCols().
	(setThreadCols): Added.
	(getProcColNames): Refactored from getColNames().
	(getThreadColNames): Added.
	(getSelectedProc): Uses update getTidDC() method from the
	SessionProcDataModel.
	(save): Saves for the thread dialog as well.
	(load): Loads for the thread dialog as well.
	* SessionProcDataModel.java (tidDC): Refactored from pidDC.
	(statRead): Changed parameters to now accept a Task, since 
	frysk.sys.Stat now handles reading thread information from /proc.
	Added a check to handle new input.
	(refreshProcRead): Refactored from refreshRead().
	(refreshThreadRead): Added.
	(addTask): Now reads from Stat.
	(getTidDC): Refactored from getPidDC().
	* ProcMenu.java (.menuItemEvent): Updated reference to the
	refactored refreshProcTree().
	* PIDColumnDialog.java (save): Updated reference to the 
	refactored getProcColNames().
	(load): Ditto.
