This specific bug is happening because we're confused by text in the a <meta> tag that looks like a tag to us. We could easily fix this specific problem and I'd like to see why this is a regression from the old code. Bug 4892428 is a far broader one and not a regression. <GMT26-Jan-2007 01:57:18GMT> Darin Adler: The key question here is: why did the Tiger version of the charset sniffer work better on this page? <rdar://problem/4836738> 29721 1 ap 2007-01-31 10:15:48 -0800 (In reply to comment #0) > The key question here is: why did the Tiger version of the charset sniffer work > better on this page? In Tiger, all unknown tags were allowed in HEAD: int id = khtml::getTagID(tmp, len); if(end) id += ID_CLOSE_TAG; ... case (ID_META+ID_CLOSE_TAG): case ID_SCRIPT: case (ID_SCRIPT+ID_CLOSE_TAG): ...other tags explicitly allowed in HEAD... case ID_HTML: case ID_HEAD: case 0: case (0 + ID_CLOSE_TAG ):     break; default:     body = true; I don't think we want to re-add this behavior. 29715 2 ap 2007-01-31 10:24:46 -0800 (In reply to comment #1) > I don't think we want to re-add this behavior. At the same time, I suspect the change was non-intentional (likely made at the time when we switched from tag IDs to AtomicStrings). 29710 3 12830 ap 2007-01-31 11:32:33 -0800 Created attachment 12830 proposed fix This patch fixes more than the regression - known tags hidden in attributes don't fool the sniffer anymore, too. 29698 4 12830 darin 2007-01-31 12:12:31 -0800 Comment on attachment 12830 proposed fix I believe that the HTML parser is tolerant of spurious quote marks in tags attribute lists -- see line 927 of HTMLTokenizer.cpp, the part that says "ignore any quotes we encounter and treat them like spaces". This code is strict about that. I'd like to see some more test cases that cover these strange quoting cases to see if there are any repercussions of that. r=me 29530 5 sam 2007-01-31 20:36:06 -0800 Landed in r19324. 29512 6 ap 2007-01-31 21:21:43 -0800 I'm going to look into how the real parser handles quote marks; will re-open if the fix needs to be corrected. 29095 7 darin 2007-02-01 09:37:14 -0800 Turns out the only reason the test case was succeeding was a bug in the code! The patch did not fix the bug, as demonstrated by the layout test. 29096 8 12830 darin 2007-02-01 09:38:44 -0800 Comment on attachment 12830 proposed fix Clearing review flag on this, since it was already landed. 29100 9 ap 2007-02-01 10:03:16 -0800 (In reply to comment #7) > Turns out the only reason the test case was succeeding was a bug in the code! > The patch did not fix the bug, as demonstrated by the layout test. I have a fix for this; looking into whether the issue with spurious quote marks can be fixed without copying most of HTMLTokenizer. 29107 10 12857 ap 2007-02-01 11:16:12 -0800 Created attachment 12857 fix the fix The spurious quotes quirk is very context-dependent, I don't see a way to support it without stateful code similar to that found in HTMLTokenizer. Maybe we should find a way to re-use that. 29146 11 12857 darin 2007-02-01 18:14:16 -0800 Comment on attachment 12857 fix the fix r=me 29161 12 ap 2007-02-01 22:03:23 -0800 Committed revision 19348.
