Any way to easily trace memory leaks in remote-viewer? A naive attempt
at "valgrind remote-viewer spice://blah" didn't turn up anything in
particular.
Have you tried with massif? It usually gives pretty good hints.
Here is "ms_print" output. I've never used massif before, is this helpful?
This massif profile doesn't show a large memory usage or any obvious leak.
Are you looking at virtual or resident (RSS) memory usage? (remember that
only RSS really "count")
Yes, RSS goes over 2GB easily with 8 hours of usage.
I have changed spice-widget.c as follows:
@@ -2205,14 +2210,15 @@
(GdkPixbufDestroyNotify)g_free, NULL);
d->mouse_hotspot.x = hot_x;
d->mouse_hotspot.y = hot_y;
- cursor = gdk_cursor_new_from_pixbuf(gtk_widget_get_display(GTK_WIDGET(display)),
- d->mouse_pixbuf, hot_x, hot_y);
+ cursor = gdk_cursor_new_for_display(gtk_widget_get_display(GTK_WIDGET(display)), GDK_FLEUR);
+ //cursor = gdk_cursor_new_from_pixbuf(gtk_widget_get_display(GTK_WIDGET(display)),
+ // d->mouse_pixbuf, hot_x, hot_y);
} else
g_warn_if_reached();
And, while it's true I only get a hand cursor no matter what, there is
no leak. I can wiggle the mouse to my heart's content and the RSS stays
flat (after initially increasing to fill the local tile cache). There
is 100% no doubt in my mind that there is a leak here. Although the
code looks correct to me.
I also tried changing gdk_cursor_unref to g_object_unref but it made no
difference.
During this test, I have a desktop I've been logged into all day, but
for the test, I disconnected remote-viewer, ran remote-viewer with
massif and ran a "webdriver" test with google-chrome. It hit a few
dozen pages with a few seconds wait time with each page. I wiggled the
mouse cursor over the page as this happened. Memory usage according to
'ps' exceeded 1.2GB by the end of the test (with valgrind/massif
overhead, of course). Then I exited remote-viewer.
Anything else you want?
Thanks,
David
