Comment on attachment 58220 [details] Patch WebCore/html/HTML5Tokenizer.cpp:126 + // We don't want to consume any more of the input stream now. Do This is confusing. I think you mean: "We were just passed data off the network in a nested call to write(). We append this data to the end, but we don't process it until we unwind to a less nested write()." or similar. WebCore/ChangeLog:18 + tokenizer. You should explain here how you also fixed the close() stuff to be more sane. WebCore/html/HTML5Tokenizer.h:111 + m_inputStream->m_last = &m_afterInsertionPoint; This line is not clear to me. WebCore/html/HTML5Tokenizer.h:117 + if (m_inputStream->m_last == &m_afterInsertionPoint) This is also not clear. I think InsertionPointRecord needs more explanation. And the ChangeLog needs to explain the close() stuff. I assume you ran all the tests?

Comment on attachment 58251 [details] Patch WebCore/html/HTML5Tokenizer.h:126 + if (m_inputStream->m_last == &m_inputStream->m_current) You're right that this would be cleaner if this code was moved onto InputStream itself. I don't really have good naming suggestions for you. :( I think my biggest gripe is that this m_last == check doesn't have a comment to explain what it's doing. I'm still confused by both of the save and restore logic, even after some sleep. :) Yes, I know what it does, but the code isn't easy to read.
