/**
|
|
* A generic ErrorHandler for the PHP engine.
|
|
*
|
|
* Provides five bit fields that control how errors are handled:
|
|
* - thrownErrors: errors thrown as \ErrorException
|
|
* - loggedErrors: logged errors, when not @-silenced
|
|
* - scopedErrors: errors thrown or logged with their local context
|
|
* - tracedErrors: errors logged with their stack trace, only once for repeated errors
|
|
* - screamedErrors: never @-silenced errors
|
|
*
|
|
* Each error level can be logged by a dedicated PSR-3 logger object.
|
|
* Screaming only applies to logging.
|
|
* Throwing takes precedence over logging.
|
|
* Uncaught exceptions are logged as E_ERROR.
|
|
* E_DEPRECATED and E_USER_DEPRECATED levels never throw.
|
|
* E_RECOVERABLE_ERROR and E_USER_ERROR levels always throw.
|
|
* Non catchable errors that can be detected at shutdown time are logged when the scream bit field allows so.
|
|
* As errors have a performance cost, repeated errors are all logged, so that the developer
|
|
* can see them and weight them as more important to fix than others of the same level.
