If any of the functionality triggered by Director::isDev() was causing deprecation errors, the system would go into an infinite loop. Since the only way to cause this is the DB checking functionality, we disable that for Deprecation. Side effect of this change: You can't show deprecation notices on a live site by forcing the session into dev mode.

/**
|
|
* Set the environment type of the current site.
|
|
*
|
|
* Typically, a SilverStripe site have a number of environments:
|
|
* - development environments, such a copy on your local machine.
|
|
* - test sites, such as the one you show the client before going live.
|
|
* - the live site itself.
|
|
*
|
|
* The behaviour of these environments often varies slightly. For example, development sites may have errors
|
|
* dumped to the screen, and order confirmation emails might be sent to the developer instead of the client.
|
|
*
|
|
* To help with this, SilverStripe supports the notion of an environment type. The environment type can be dev,
|
|
* test, or live.
|
|
*
|
|
* You can set it explicitly with Director::set_environment_tpye(). Or you can use
|
|
* {@link Director::set_dev_servers()} and {@link Director::set_test_servers()} to set it implicitly, based on the
|
|
* value of $_SERVER['HTTP_HOST']. If the HTTP_HOST value is one of the servers listed, then the environment type
|
|
* will be test or dev. Otherwise, the environment type will be live.
|
|
*
|
|
* Dev mode can also be forced by putting ?isDev=1 in your URL, which will ask you to log in and then push the
|
|
* site into dev mode for the remainder of the session. Putting ?isDev=0 onto the URL can turn it back.
|
|
*
|
|
* Test mode can also be forced by putting ?isTest=1 in your URL, which will ask you to log in and then push the
|
|
* site into test mode for the remainder of the session. Putting ?isTest=0 onto the URL can turn it back.
|
|
*
|
|
* Generally speaking, these methods will be called from your _config.php file.
|
|
*
|
|
* Once the environment type is set, it can be checked with {@link Director::isDev()}, {@link Director::isTest()},
|
|
* and {@link Director::isLive()}.
