It seems that if bufferedAmount() is going to parse the buffer, then it should have a state machine, and also ASSERT that it knows about the current frame type. I don't know how to reasonably implement that, since the buffer won't necessarily start on frame boundary. But also, this seems quite slow, perhaps it would be better to store data size separately (again, it can be a challenge to update properly). Or even to try and get the spec changed back per implementor feedback. Do we have a test checking how null characters go over WebSocket? 195853 3 ukai 2010-03-03 18:41:34 -0800 (In reply to comment #2) > (From update of attachment 49876 [details]) > Isn't 0x00 allowed to be inside of message text? 0xff can never occur in UTF-8, > but 0x00 can be there.

Or even to try > and get the spec changed back per implementor feedback. Yes, I prefer previous spec. I'll ask the spec changed back. > Do we have a test checking how null characters go over WebSocket? Not yet. I'll add. 196392 4 50093 ukai 2010-03-05 02:15:02 -0800 Created attachment 50093 Patch 196578 5 ap 2010-03-05 12:25:57 -0800 I'm not sure if we want to make this change even if we can't get the spec changed back. 205675 6 50093 ap 2010-03-29 14:48:41 -0700 Comment on attachment 50093 Patch This doesn't currently need review, removing the flag. The behavior of bufferedAmount is still being actively discussed on whatwg mailing list. 871469 7 tyoshino 2013-04-08 23:03:20 -0700 The patch is obsolete (for Hixie 75 style framing). Needs discussion on the spec. Maybe reopening https://www.w3.org/Bugs/Public/show_bug.cgi?id=9083 if necessary. Marking this bug as WONTFIX for now. 49876 2010-03-02 20:53:56 -0800 2010-03-05 02:14:57 -0800 Patch bug-35571-20100303135354.patch text/plain 4757 ukai
