Wez Furlong 99e290f882 Fix for Bug #24189: possibly unsafe select(2) usage. ... We avoid the problem by using poll(2). On systems without poll(2) (older bsd-ish systems, and win32), we emulate poll(2) using select(2) and check for valid descriptors before attempting to access them via the descriptor sets. If an out-of-range descriptor is detected, an E_WARNING is raised suggesting that PHP should be recompiled with a larger FD_SETSIZE (and also with a suggested value). Most uses of select(2) in the source are to poll a single descriptor, so a couple of handy wrapper functions have been added to make this easier. A configure option --enable-fd-setsize has been added to both the unix and win32 builds; on unix we default to 16384 and on windows we default to 256. Windows FD_SETSIZE imposes a limit on the maximum number of descriptors that can be select()ed at once, whereas the unix FD_SETSIZE limit is based on the highest numbered descriptor; 256 should be plenty for PHP scripts under windows (the default OS setting is 64). The win32 specific parts are untested; will do that now.		2004-09-17 12:44:56 +00:00
