Now if you want to come up with a test harness that claims to stress-test some given code-base, with version numbers of all the under-lying code, and hardware, come to think of it, and try to track the amount of testing that has been done, and assign probability curves to the thread-safeness of any given combination... It ain't gonna be no simple table, though, really. You might get somebody to say "Core PHP is Thread-safe" They might even believe that. They *might* even be right. For their version of PHP. On their OS. Under that *version* of their OS. With their hardware. It don't mean a whole lot to anybody who doesn't have that *exact* same setup. You'd almost have to work out a list of all known variables, and then a weighting system for (number-of-hours-run X number-of-concurrent-processes) multiplied by the server load to give each report a "score" If I tell you it's "been fine" on my low-traffic servers, it don't mean squat. If Rasmus tells you "PHP X + MySQL Y + OS Z == Good" on Yahoo, that has some meaning, but not a whole lot if you change *any* of the variables in the equation. So then, you'd have a very large (and quite sparse, probably) matrix of the probability that any given combination of every software package (and hardware?) is thread-safe. Not saying it's not a Good Idea, nor that you shouldn't be doing this: I just want you to understand that you've severely under-estimated the scale and scope of the problem to be addressed, and have a concomitant simplisitic design going here. Make it complex enough to be useful, and make it easy to search and report on various combinations, it could be a real boon. But if your site just says "PHP 4.1.3 + MySQL 3.23.4 == Good"... I'm not going to put much faith in that for thread-safety. But maybe I'm just a negative guy :-) -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
