Debugging facilities

Some improvements to make life easier

Administrators Thanked: 265 mal	That MySQL puzzle is solved by adding backtrace to sed_diefatal(). Any more wishes? OK, I've added a few simple functions which make manual debugging easier: sed_assert($var1,..) - use it to print variables on a blank screen immediately sed_backtrace() - prints backtrace (files, functions, parameters). By default blanks the screen, call sed_backtrace(FALSE) to see backtrace within normal output flow. sed_vardump() - attempts to print contents of all global variables recursively. Doesn't print all of them because it has length limitation. By default blanks the screen, call sed_vardump(FALSE) to see vardump within normal output flow. sed_diefatal() was modified and a new option was added to config.php: /** * Defines whether to display debugging information on critical errors. * Comment it on production sites if you wish. / define('SED_DEBUG', TRUE); By default this switch is on. On some production sites you'd like to disable it because debug info contains file paths. When this switch is defined, sed_diefatal() prints backtrace. It is extremely useful to track MySQL errors. May the Source be with you! Dieser Beitrag wurde von Trustmaster (am 3. Mai 2009, 17:41, vor 16 Jahre) bearbeitet*

OK, I've added a few simple functions which make manual debugging easier:

sed_assert($var1,..) - use it to print variables on a blank screen immediately
sed_backtrace() - prints backtrace (files, functions, parameters). By default blanks the screen, call sed_backtrace(FALSE) to see backtrace within normal output flow.
sed_vardump() - attempts to print contents of all global variables recursively. Doesn't print all of them because it has length limitation. By default blanks the screen, call sed_vardump(FALSE) to see vardump within normal output flow.

sed_diefatal() was modified and a new option was added to config.php:

/**
 * Defines whether to display debugging information on critical errors.
 * Comment it on production sites if you wish.
 */
define('SED_DEBUG', TRUE);

By default this switch is on. On some production sites you'd like to disable it because debug info contains file paths. When this switch is defined, sed_diefatal() prints backtrace. It is extremely useful to track MySQL errors.

May the Source be with you!
