Summary HTML parser double quote error recovery doesn't match Firefox 3.0.x

Reported 2009-02-15 18:45:27 PST

* SUMMARY The page linked to in the URL is blank when loaded in Safari (WebKit) due to the way error recovery is handled for a missing double-quote character within <script></script> tags. The same page is displayed fully in Firefox 3.0.x. * STEPS TO REPRODUCE 1. Launch Safari/WebKit. 2. Open URL or attached test case. * EXPECTED RESULTS The contents of the page should be displayed. * ACTUAL RESULTS Nothing is displayed. * REGRESSION The original page and the test case both are blank in Safari 2.0.4, so this is likely not a regression.

Created attachment 27688 [details] further reduced test case In fact, the missing quote in JavaScript is handled correctly - it's another missing quote in <img alt="> that's causing the problem.

Thanks, Alexey! Note that WebKit matches the html5lib parser <http://james.html5.org/parsetree.html>: http://james.html5.org/cgi-bin/parsetree/parsetree.py?uri=https%3A%2F%2Fbugs.webkit.org%2Fattachment.cgi%3Fid%3D27688
