#50652 [WFx]: time call optimization

ID: 50652 User updated by: robert_xp at gmx dot net Reported By: robert_xp at gmx dot net Status: Wont fix Bug Type: Performance problem PHP Version: 5.3.1 New Comment: I'm such an idiot. Sorry, fixed. Previous Comments: ------------------------------------------------------------------------ [2010-01-04 15:19:35] rasmus@php.net Your patch it also reversed. ------------------------------------------------------------------------ [2010-01-04 15:11:49] robert_xp at gmx dot net Yes, that's right. I think this is the only point, that speaks really against this solution but most scripts should be executed in < 0.x sec and calling time(NULL) many times can be optimized this way. A good improvement could be, applying the patch and change the SAPI handling to check against a config variable if a optimized time handling should be used - with default using the old approach. ------------------------------------------------------------------------ [2010-01-04 12:25:31] derick@php.net We can't do this, as for longer running scripts the value as returned by time() can change (like once every second). ------------------------------------------------------------------------ [2010-01-04 12:18:06] robert_xp at gmx dot net Description: ------------ Sure, it is not so critical to patch this but you use ever time(NULL) to get the current time in most functions. There is a better way going over the SAPI interface and retrieve a cached value. I published also a patch for all time(NULL/0) calls on http://www.xarg.org/2009/12/php-hacking/ I also hacked the FCGI sapi to get the time value direclty from the webserver - yes it is not supported by default. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=50652&edit=1
