Hi,
Working on CSS error reporting I found that CSS grammar (Source/WebCore/css/
CSSGrammar.y.in <http://cssgrammar.y.in/>) handles invalid_block's in
different parts of CSS declaration differently.
For instance, in current grammar test
<style>
.malformed5 {color: red; {}}
#test5 {
display:none;
}
</style>
works fine while
<style>
.malformed13 {color: red; color: red; {}; color: red}
#test13 {
display:none;
}
</style>
fails. In the second case parser log shows it drops opening brace and
closing braces considers as and of the rule.
I have a patch that fixes it: https://bugs.webkit.org/show_bug.cgi?id=112880
It makes error recovery in the end and in the middle (when error is
following by semicolon) of delcaration list equivalent.
Does anybody feel comfortable to review it?
Sergey
