2013-02-23Updated exit codes as constant valuesDaniel Hunsaker1-1/+1
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. Signed-off-by: Daniel Hunsaker <danhunsaker@gmail.com>

Note: The Driver libary tests seem to depend on that, so one occurence in CI_Loader is left until we resolve that.

On the first list_fields call, the field pointer is moved to the end of the list of fields. This change ensures that the pointer is positioned at the start of the field list before grabbing the names. Signed-off-by: Chris Buckley <chris@cmbuckley.co.uk>

2013-01-25Updated all cases of exit() to return a valid codeDaniel Hunsaker1-1/+1
Specific codes are as follows, but can easily be changed if a different order/breakdown makes more sense: - 0: Success; everything executed as planned - 1: Configuration Error; something is wrong with/in the configuration file(s) - 2: Class Not Found; what it says - 3: Driver Method Unsupported; the method you're trying to use on a Driver doesn't exist - 4: File Not Found; 404 error - 5: Database Error; something is broken in the database somewhere - 6: Invalid Input; the user attempted to submit a request with invlaid characters in 1+ key names 7 through 26 are reserved for future use - 27: Generic Error; generated by show_error() when the status code is >= 100 28 through 127 are errors generated by user applications, normally by using show_error() with a status code below 100 128 through 254 should not be used by applications, as they are reserved by system-level functions - 255: PHP Fatal Error; automatically generated by PHP for fatal errors, and therefore not allowed for our use Status codes below 100 are shifted up by 28 to place them in the user error range. It may make more sense to have these codes left alone and instead shift the CI errors into the 101 through 127 space, but that's not what I opted for here. It would probably also be a good idea to replace the hard-coded numbers with constants or some such, but I was in a bit of a hurry when I made these changes, so I didn't look around for the best place to do this. With proper guidance, I could easily amend this commit with another that uses such constant values. Signed-off-by: Daniel Hunsaker <danhunsaker@gmail.com>
2013-01-24Move db_select() call from CI_DB_driver::initialize() to db_connect()Andrey Andreev3-15/+27

2012-12-04Remove CI_DB_oci8_result::data_seek()Andrey Andreev1-63/+0
It can only call oci_execute() in order to reset the pointer to 0, the oci8 driver doesn't support setting the pointer. Due to the result_object(), result_array() and custom_result_object() calling data_seek() every time prior to fetching the result set, this only causes the query to be executed twice. All of the three methods now cast from existing result_object and/or result_array sets, so the probability to ever need to really fetch the result set again is practically zero and so this method doesn't bring any benefit.
