filestat patch : convert to access().

Hello, Attached is the proposed patch to convert to access(). While testing, I discovered that access() always returns success if getuid()=root. So, I had to add a check based on the permissions just for this case. :-( Benefits of this patch : 1) Don't mess anymore with getgroups, scanning all groups and bit-mask-check if an operation (read, write, execute) is authorized. Decrease code complexity a lot. 2) Get some more abstraction on the function level : #define php_access access if we're not PHP_WIN32 // Needs some work from windows gurus, see below. 3) Determine rights using access(), so it's much less user/group/other dependant. 4) If the system supports ACLs and access() checks them, it should work. Drawback : Calls access() three times. WIN32 guys : Everything is ready to check permissions in the Windows way, you don't have to emulate bitmasks or any unix-likies anymore, the only function you need to #define is php_access(const char *filename,READ|WRITE|EXECUTE). Hartmut, if you think this patch is ok, could you please commit it to cvs. I might ask for cvs access in the future but I don't have one at the moment. Flavien Lebarbé --- Open Care
