Zoph/Solving Problems/Debug< Zoph(Redirected from Zoph/Solving Problems/Logging in Zoph 0.8.1 and later)
In case something goes wrong and Zoph's normal error reporting does not give sufficient information to solve the problem, you can enable debugging. Debugging is controlled through 3 different options in config.inc.php:
Each logging message has been categorized in a subject:
|log::VARS||Messages regarding setting of variables|
|log::LANG||Messages regarding the translation of Zoph|
|log::LOGIN||Messages regarding the Login procedure|
|log::REDIRECT||Messages regarding redirection|
|log::DB||Messages regarding the database connection|
|log::SQL||Messages regarding SQL Queries|
|log::XML||Messages regarding XML creation|
|log::IMG||Messages regarding image creation|
|log::IMPORT||Messages regarding the import functions|
and each message has gotten a severity indiction, that indicates how "bad" the situation is:
|log::DEBUG||Debugging messages, Zoph gives information about what it's doing.|
|log::NOTIFY||Notification about something that is happening which is influencing Zoph's program flow|
|log::WARN||Warning about something that is happening|
|log::ERROR||Error condition, something has gone wrong, but Zoph can recover|
|log::FATAL||Fatal error, something has gone wrong and Zoph needs to stop execution of the current script.|
|log::NONE||Do not display any messages|
As mentioned before, 3 new configuration options have been added to config.inc.php.
This setting configures a log level that is always displayed, no matter which subject the message is in. By default this is set to log::FATAL, which means that any message that has a severity of FATAL or worse is displayed. Since log::FATAL is the worst kind of message, only log::FATAL messages will be displayed. If you would set it to log::WARN, any message with a severity of WARN or worse will be displayed, hence any FATAL, ERROR or WARN message will be displayed. A special severity level has been added to surpress all messages: log::NONE
All messages which indicate an error or a fatal error will be displayed.
All messages, except debug-level messages will be displayed.
All messages will be displayed.
This setting works in the same way as the previous one, except that only messages for a specific severity will be displayed; it is used in combination with LOG_SUBJECT to achieve this.
define('LOG_SEVERITY', log::ERROR); define('LOG_SUBJECT', log::LANG);
All messages which indicate an error or a fatal error, regarding the translation of Zoph will be displayed.
define('LOG_SEVERITY', log::NOTIFY); define('LOG_SUBJECT', log::DB);
All messages, except debug-level messages, regarding the database connection will be displayed.
define('LOG_SEVERITY', log::DEBUG); define('LOG_SUBJECT', log::SQL);
All messages regarding SQL-queries will be displayed. (since the SQL queries themselves are considered debug information, you will need this setting to show them.)
With this setting you can control for which subjects you want to see the messages. There is a special subject to show all messages: log::ALL.
You can also combine multiple subjects, using the | (or) sign and the ~ (not) sign.
define('LOG_SEVERITY', log::ERROR); define('LOG_SUBJECT', log::LANG | log::IMG);
All messages which indicate an error or a fatal error, regarding the translation of Zoph or images will be displayed.
define('LOG_SEVERITY', log::NOTIFY); define('LOG_SUBJECT', log::ALL | ~log::SQL);
All messages, except debug-level messages, except those regarding SQL queries are displayed.
define('LOG_SEVERITY', log::DEBUG); define('LOG_SUBJECT', log::ALL ~(log::REDIRECT | log::DB));
All messages except those regarding redirects or the database connection will be displayed.
