#37025 [Opn]: FD_SETSIZE error

ID: 37025 User updated by: linuxapps at yahoo dot com Reported By: linuxapps at yahoo dot com Status: Open Bug Type: Sockets related Operating System: Fedora Core 4 PHP Version: 5.1.2 New Comment: Correction. Bug appears in CLI and CGI modes. Previous Comments: ------------------------------------------------------------------------ [2006-04-09 16:59:29] linuxapps at yahoo dot com Description: ------------ When compiled with --disable-cgi, PHP CLI throws an error on socket_select() when socket count > 1024. It appears that the CLI installation defaults to FD_SETSIZE=1024 regardless of what is set at compile time via --enable-fd-setsize. PHP CGI, however, works properly. This error happens identically to both sockets and socket streams (e.g. stream_select()). The code example uses sockets. Reproduce code: --------------- http://fourthround.com/bugs/server.txt http://fourthround.com/bugs/stester.txt Expected result: ---------------- As long as the OS's open file limit has not been exceeded PHP CLI should not throw an error when compiled with --enable-fd-setsize=4096 and socket_select on over 1024 sockets. Actual result: -------------- Warning: socket_select(): You MUST recompile PHP with a larger value of FD_SETSIZE. It is set to 1024, but you have descriptors numbered at least as high as 1054. -- enable-fd-setsize=2048 is recommended, but you may want to set it to equal the maximum number of open files supported by your system, in order to avoid seeing this error again at a later date. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=37025&edit=1
