Description Christian Wäckerlin 2008-09-13 16:19:56 UTC 
Please describe the problem:
Gedit freezes if big HTML files are opened. Syntax highlighting seems to be the probem.

Steps to reproduce:
1. Download some big HTML file, i.e. wget http://www.imdb.com/chart/top
2. Open it in gedit and scroll


Actual results:
Gedit freezes.

Expected results:
It works

Does this happen every time?
Yes. If syntax highlighting is disabled, the problem does not occur.

I can confirm that gedit gets unresponsive for a significant time when opening a big file such as top.html from http://www.imdb.com/chart/top -- but gedit never actually freezes.

Yes, if you turn off syntax highlighting, performance increases to a tolerable level.

Speculation: perhaps the syntax highlighting code needs to be revisited for some optimization?

I am using gedit 2.22.3.
Comment 2 Christian Wäckerlin 2008-09-21 22:19:40 UTC 
Actually, I think the problem is that in top.html, there is a line with about 100'000 bytes length. 

This probably causes the performance problems.
Comment 3 Sébastien Wilmet 2014-07-21 10:52:55 UTC 
Very long lines are not well supported by GtkTextView, the GTK+ widget used by gedit.
