Req #62509 [Com]: chroot() is disabled with ZTS enabled

Edit report at https://bugs.php.net/bug.php?id=62509&edit=1 ID: 62509 Comment by: streaky at mybrokenlogic dot com Reported by: streaky at mkybrokenlogic dot com Summary: chroot() is disabled with ZTS enabled Status: Not a bug Type: Feature/Change Request Package: Directory function related Operating System: Anything but windows? PHP Version: Irrelevant Block user comment: N Private report: N New Comment: There are situations where you need to regardless - for example runkit needs ZTS - if you need runkit and chroot() currently you can't do it without the aforementioned hack. Besides this *is* a threaded context. There's no good thread safety reason why chroot() would be disabled besides the "it's hard to get it to configure like that" is there? I'm okay with the way it is just in principle it seems wrong to me - personally I can do it in a patch... Previous Comments: ------------------------------------------------------------------------ [2012-07-09 05:29:27] laruence@php.net maybe we can always return false in ZTS build, and trigger a warning. ------------------------------------------------------------------------ [2012-07-08 21:02:35] johannes@php.net You shouldn't use ZTS binaries in non-threaded context. They need more memory, they are slower, they are harder to debug in case of critical errors. That aside: We have no good mechanism to disable it easily in one context only. ------------------------------------------------------------------------ [2012-07-08 17:00:46] streaky at mkybrokenlogic dot com Description: ------------ chroot() seems to be arbitrarily disabled with ZTS enabled. It seems like it is disabled because when ZTS is -usually- used it is with a sapi that requires thread safety but this isn't always the case. AFAIK there isn't a good reason for it, I assume it's some sort of oversight - a cheap and cheerful way to achieve the above, but it doesn't account for all circumstances so you have to go hacking on the source code in about 3 different places. It probably should be as is *except* for if CLI and possibly CGI is the SAPI. Test script: --------------- <?php var_dump(chroot("/chroot/me/here/")); Expected result: ---------------- bool(true) Actual result: -------------- Fatal error: Call to undefined function chroot() ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=62509&edit=1
