Before that fix, starting dillo with valgrind "solved" the problem and shows some invalid reads and writes. Now these invalid reads and writes are gone. Greetings Andreas Kemnade

dillo CSS and charset

by furaisanjin＠gmail.com

Hi all. I created new subject thread since the original one becomes quite long and. I found one difference between dillo-2.0 and dillo-css. there was a_Decode_charset_init calling at Cache_parse_header in cache.c when HTTP server Content-Type was detected but there isn't this in dillo-css. Because if HTTP server Content-Type is same as META content-type, there isn't any chance to call a_Decode_charset_init. This is one reason why the page is drawn properly. I still don't figure out another timing issue yet. Regards, furaisanjin

[bug]: hang in Css_parse_declaration()

by onepoint＠starurchin.org

The following HTML makes dillo hang and burn 100% CPU. <html> <body> <span style="{}">a</span> </body> </html> The bug does not appear if the span contains no text, or only whitespace. The stack trace always ends inside Css_parse_declaration(). The line number varies, but seems to be always one of 809, 823 or 963. You can see the same bug online at http://www.nation.co.ke/News/-/1056/515354/-/u1acuw/-/index.html Regards, Jeremy Henty

Excellent customer service :) It's not the proper solution though. Here's the plan to apply rules according to http://www.w3.org/TR/CSS21/cascade.html#specificity: * For each CssRule compute the specificity according to http://www.w3.org/TR/CSS21/cascade.html#specificity * Store the rules in RuleList sorted by this specificity. * In CssStyleSheet::apply() merge-sort the 4 ruleLists with potentially matching rules and apply them in the order given by their specificity. If anyone feels like implementing it - go ahead :) Cheers, Johannes

I may not need to keep html->repush_after_head = true but > I'm not sure. I was wrong. This doesn't help all cases. The problem seems that when the page is repushed, somehow decoder_charset isn't called so that charset conversion doesn't happens. >>> Another issue is that if style sheet specified none Japanese font and >>> the font exists on my machine, then of course the page isn't readable >>> at all.

If I use 14 instead of 12, it's a lot more readable. (Or is the 12 important for some CSS reason involving picas?)
