Aside from testing, perhaps simplification of pages, see attached example, which has all stripped off which is not neccessary to reproduce the bug. (It is largely intuition to get there, so perhaps it is best when I do this.) Expect a fix soon. Sebastian

Reddit regression

by onepoint＠starurchin.org

Things are progressing nicely (I have already abandoned two problem reports because they were fixed in the meantime) but there has been an unfortunate regression - a few days ago Reddit comment threads started thrashing the CPU. Example: http://www.reddit.com/r/haskell/comments/24rcf0/hourglass_a_new_simpler_tim… This is bad news for me as I follow a lot of subreddits. I hope it can be fixed soon. If there is anything I can do to help find the problem please say so. Regards, Jeremy Henty

Your first suggestion looks quite reasonable. Please try it and make some field tests. I'm currently working on the double imgbuf problem... -- Cheers Jorge.-

I wish them luck. HTML5 is the most ridiculous possible document.

I remember short ago, reading somewhere in the news that there were funds and a call for people with expertise to work on designing an alternative technology for the web (to try to tackle the enormous amount of complexity full blown browsers have become not to mention the disparate user experience this creates). -- Cheers Jorge.-

Then, it looks like requiring it again in this case may be the way to go (I seem to recall there were lots of unterminated NBSP). A long long time ago people thought that SGML was the final solution, then XML, then HTML5, now they're looking for an alternative technology to base the web upon... -- Cheers Jorge.-

This msg says that it was changed because it wasn't required under certain conditions. HTML4 spec gives it as: Note. In SGML, it is possible to eliminate the final ";" after a character reference in some cases (e.g., at a line break or immediately before a tag). In other circumstances it may not be eliminated (e.g., in the middle of a word). We strongly suggest using the ";" in all cases to avoid problems with user agents that require this character to be present. ...and there's an "IIRC" in the msg that XHTML requires it. The HTML5 spec requires a terminating ';' in all cases.

Regarding this "text-indent: 9999px", I've seen this a couple of time and it seems to be a common trick [1]. Cheers, Johannes [1] http://luigimontanez.com/2010/stop-using-text-indent-css-trick/

Yeah, this is why I was considering just changing the get_attr case, but of course I don't want to make the code messy and complicated unless I need to. > It'd be good to find the reason for the change before reverting it. > I don't remember it now, but I do remember it was because the other way > started to be perceived as worst in some sense. > > Maybe GMANE has the mailing list archives... I guess I'll put some time into digging around. Maybe it happens out there and I just don't hear about it, but I wonder why projects don't tend to keep track -- in some organized fashion by topic, like in a wiki or group of static web pages or something -- all of the decisions made on various issues and the reasoning surrounding them, since it's hard to remember details for years, people come and go, etc.
