I seem to be getting a weird allocation of uints when using
Gtk.Application.Invoke
If i run the following code through heap-buddy:
using System;
using Gtk;
using System.Threading;
public class MainWindow : Gtk.Window
{
Gtk.Label Label1;
public MainWindow() : base ("Test")
{
this.DeleteEvent += new DeleteEventHandler(OnDeleteEvent);
Label1 = new Gtk.Label("");
this.Add(Label1);
this.ShowAll();
Thread x = new Thread(new ThreadStart(test));
x.IsBackground = true;
x.Start();
}
int ctr = 0;
void test()
{
while(true)
{
Gtk.Application.Invoke( delegate {
ctr++;
Label1.Text = ctr.ToString();
});
Thread.Sleep(10);
}
}
protected void OnDeleteEvent( object sender, DeleteEventArgs e)
{
Application.Quit();
e.RetVal = true;
}
}
I'll get a lot of uints allocated on the heap. Most seem to be cleaned up by
the garbage collection, but still it doesnt seem quite right. Here is the
output from heap-buddy, after running for about 5 seconds:
$ heap-buddy types 10 sorted by count
Type # Total AvSz AvAge BT#
uint 557439 6.4M 12.0 0.0 18337

System.Collections.ArrayList 9182 179k 20.0 0.0 9182
System.Text.StringBuilder 9179 215k 24.0 0.0 9179
Is this a bug, or am I just doing something very wrong. That just seems like
a LOT of uints.
This is basically a stub from another Gtk# program I'm working on that is
fairly thread intestive. I don't remember seeing this kind of behavior
before 1.2. I am running mono 1.2.2, on Fedora Core 5.
Any help would be greatly appriciated. Thanks
