Comment 1 Paolo Borelli 2006-01-30 12:53:16 UTC 
I can reproduce the freeze also with gtksourceview's test-widget. moving to GtkSourceView

https://launchpad.net/distros/ubuntu/+source/gtksourceview/+bug/52975 mentions http://patrickguignot.free.fr/sf/nouvelles_sf.html as another 'test case'. Bumping Version.
Comment 3 Paolo Maggi 2006-07-26 13:28:20 UTC 
If I load the files, gedit uses 100% of CPU for a few minutes, then it start working quite well.
So, AFAIK, the problem is that the syntax hl is too slow with very big XML files.
May be this bug is somewhat related to bug #330406.
Comment 4 Paolo Maggi 2006-07-26 13:36:27 UTC 
Muntyan: we have seen that on the sample XML attached to this bug the new syntax hl engine does not block but it is very very slow when highlighting text. You can litteraly see it highlighting the text line after line.

Should be much better now. I guess it was the problem with the tree, that engine walked all the nodes.
Comment 6 Yevgen Muntyan 2008-06-20 01:35:45 UTC 
Closing as fixed. Both the engine and the lang file have been much improved.
