System Configuration File (system)

The files system.php in /conf directory and system.php in environment subdirectories is used by Kernel and other core libraries.

Like other configuration files of the framework you can add configuration entries and change pre-defined sets, but can not delete it.

Pre-defined configurations

• 'debug' - (boolean) Turns on/off the system debug.
• 'ignore_deprecated' - (boolean) Sets the error handler system to ignores or catches the deprecated funcion warnings.
• 'rewrite_url' - (boolean) Turns URL rewrite on/off.
• 'cache-control' - (string) The value to header HTTP/1.1 Cache-Control.
• 'authentication' - (array) A key pair user/pass to HTTP authentication simple access control. The array must be define is the following format `['user' => 'username', 'pass' => 'password']`. Leave it empty to turns off simple HTTP autentication access.
• 'developer_user' - Query string variable name to turns developer mode on/off.
• 'developer_pass' - Value to enable developer/dba mode.
• 'dba_user' - Query string variable name to turns on/off the DBA mode.
• 'bug_authentication' - Turns on the HTTP simple authentication to system errors log. Must by an array in following format: `['user' => 'username', 'pass' => 'password']`. Leave it empty to turns off simple HTTP autentication access to error log system.
• 'assets_source_path' - Folder path for source of the asset files.
• 'assets_path' - Folder path for minified asset files.
• 'maintenance' - Puts the system under maintenance mode and all requests will reply with a HTTP 503 error.
• 'session' - Session configurations.

Session configurations

The 'session' entry is an array containing other entries that configure the framework session system.

• 'type' - String with the type of session storage. Possible values are `'file'`, `'memcached'` and `'database'`.
• 'name' - The name of the session cookie.
• 'domain' - The session master domain cookie.
• 'expires' - Session expiration time in minutes.

Session storage types

The framework natively supports the following types of user session control:

• 'file' - Storage on file. This is the default format supported by PHP.
• 'memcached' - Memcache service storage. Requires an external Memcache server or the MemcacheD service running on the computer.
• 'database' - Relational database table storage. It is recommended to use memory-type tables. If your DBMS does not support this type of table, its use is discouraged.

Developer mode

Springy has configuration entries that allow system developers to turn on debug mode in environments where it is off and access environments placed in maintenance mode.

The 'developer_user' and 'developer_pass' entries are understood by the Kernel as a special access if their values are received as key-values passed by query string, as follows: www.mysite.com/?{$developer_user}={$developer_pass}

For example, suppose that the configuration entries define as follows:

[
    // ... other configuration entries
    'developer_user' => 'silvio',
    'developer_pass' => 'santos',
];

So if the developer sends the query string ?silvio=santos into the URI, the developer mode will be on for the entire session.

To disable developer mode without having to clear cookies or close the browser, simply enter the following query string string: ?{$developer_user}=off

Therefore the value of the 'developer_pass' entry can never be 'off', since it will not be possible to activate the developer mode.

DBA mode

Like the developer mode, the framework has a mechanism to enable debugging, displaying all the SQL commands executed during the iteration.

The 'dba_user' configuration entry defines the name of the query string variable that enables or disables the debugging of SQL commands.

To enable this mode, you must first enable developer mode and then DBA mode or do it together as follows: www.mysite.com/?{$developer_user}={$developer_pass}&{$dba_user}={$developer_pass}

For example, let's assume that the configuration entries contain the following values:

[
    // ... other configuration entries
    'developer_user' => 'silvio',
    'developer_pass' => 'santos',
    'dba_user'       => 'vemaih',
];

So to activate the DBA mode the developer should put the query string ?silvio=santos&vemaih=santos into the URI.

To disable DBA mode, the query string must contain the following: ?{$dba_user}=off
