[PHP-DEV] implementing posix_setrlimit
Hello- We are planning on implementing posix_setrlimit() as a sister function to posix_getrlimit() to: a) protect against runaway/buggy programs from bringing the server down and b) to allow a program that genuinely requires a lot of CPU time and/or memory to ask for it (by modifying its soft limit all the way up to an administrator-imposed hard limit) Is there any particular reason than this has not already been implemented, and if not, would it be a valid contribution to the PHP language?

John, I would guess that the reason it was never implemented was due to the problems this could pose as a webserver module. If you would like to submit your patch, make sure you limit the function to the CGI SAPI. (or you can just send the patch and someone can add that) -Jason - Original Message - From: John Donagher [EMAIL PROTECTED] To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Sent: Tuesday, October 02, 2001 3:27 PM Subject: [PHP-DEV] implementing posix_setrlimit Hello- We are planning on implementing posix_setrlimit() as a sister function to posix_getrlimit() to: a) protect against runaway/buggy programs from bringing the server down and b) to allow a program that genuinely requires a lot of CPU time and/or memory to ask for it (by modifying its soft limit all the way up to an administrator-imposed hard limit) Is there any particular reason than this has not already been implemented, and if not, would it be a valid contribution to the PHP language?

Re: [PHP-DEV] implementing posix_setrlimit
Hi Jason- We haven't yet implemented it nor have we looked in depth at the possible intricacies of an implementation .. but from a high level we think it does make sense even then, since this is a system call that any UNIX process should be able to utilize. In any event, it only makes sense for us in an ISAPI context, as that is the context in which our application runs. There was a thread a few years ago about a possible setrlimit() implementation, but it was deferred since there is an option for setting some process limitations at the webserver level .. unfortunately those aren't enough for us.
