From 3b5b7f48848d098c6190781f8790a1b0dcb0217c Mon Sep 17 00:00:00 2001 From: Daniel Hunsaker Date: Fri, 22 Feb 2013 19:17:56 -0700 Subject: Updated exit codes as constant values Re-allocated exit status codes according to three references, which follow: BSD sysexits.h:http://www.gsp.com/cgi-bin/man.cgi?section=3&topic=sysexits GNU recomendations:http://www.gnu.org/software/libc/manual/html_node/Exit-Status.html Bash scripting:http://tldp.org/LDP/abs/html/exitcodes.html The GNU recommendations stem from and expand upon the standard C/C++ library (stdlibc) definitions, while also suggesting some best-practice conventions which happen to prevent exit status code collisions with bash, and probably other shells. The re-allocated codes are now mapped to constant values, set in *application/config/constants.php*, and used throughout the CodeIgniter core. They would additionally be used in *index.php*, but the constants file hasn't been loaded at that point, so the integer values are used instead, and a comment follows each such use with amplifying information on why that particular value was selected. Finally, the errors documentation has been updated accordingly.
