static |
Get a PSR-3 log event context from a Throwable.
Creates a structured array containing information about the provided throwable that can be used to augment a log message sent to a PSR-3 logger.
Throwable | $e | |
string | $catcher | CAUGHT_BY_* class constant indicating what caught the error |
Definition at line 584 of file MWExceptionHandler.php.
|
static |
Get a message formatting the throwable message and its origin.
Despite the method name, this is not used for logging. It is only used for HTML or CLI output by MWExceptionRenderer.
Throwable | $e |

|
static |
Get a normalised message for formatting with PSR-3 log event context.
Must be used together with getLogContext()
to be useful.
Throwable | $e |

|
static |
Return a copy of a throwable's backtrace as an array.
Like Throwable::getTrace, but replaces each element in each frame's argument array with the name of its class (if the element is an object) or its type (if the element is a PHP primitive).
Throwable | $e |
Definition at line 468 of file MWExceptionHandler.php.
|
static |
Generate a string representation of a throwable's stack trace.
Like Throwable::getTraceAsString, but replaces argument values with their type or class name, and prepends the start line of the throwable.
Throwable | $e |
Definition at line 410 of file MWExceptionHandler.php.
|
static |
Get a structured representation of a Throwable.
Returns an array of structured data (class, message, code, file, backtrace) derived from the given throwable. The backtrace information will be redacted as per getRedactedTraceAsArray().
Throwable | $e | |
string | $catcher | CAUGHT_BY_* class constant indicating what caught the error |

|
static |
If the exception occurred in the course of responding to a request, returns the requested URL.
Otherwise, returns false.

static |
Handler for set_error_handler() callback notifications.
Receive a callback from the interpreter for a raised error, create an ErrorException, and log the exception to the 'error' logging channel(s).
int | $level | Error level raised |
string | $message | |
string | null | $file | |
int | null | $line |
Definition at line 256 of file MWExceptionHandler.php.
|
static |
Exception handler which simulates the appropriate catch() handling:
try { ... } catch ( Exception $e ) { $e->report(); } catch ( Exception $e ) { echo $e->__toString(); }
Throwable | $e | |
string | $catcher | CAUGHT_BY_* class constant indicating what caught the error |
Definition at line 237 of file MWExceptionHandler.php.
|
static |
Callback used as a registered shutdown function.
This is used as callback from the interpreter at system shutdown. If the last error was not a recoverable error that we already reported, and log as fatal exception.
Special handling is included for missing class errors as they may indicate that the user needs to install 3rd-party libraries via Composer or other means.

Callback to use with PHP's set_exception_handler.

Install handlers with PHP.
bool | $logExceptionBacktrace | Whether error handlers should include a backtrace in the log. |
bool | $propagateErrors | Whether errors should be propagated to PHP's built-in handler. |

|
static |
Serialize a Throwable object to JSON.
The JSON object will have keys 'id', 'file', 'line', 'message', and 'url'. These keys map to string values, with the exception of 'line', which is a number, and 'url', which may be either a string URL or null if the throwable did not occur in the context of serving a web request.
If $wgLogExceptionBacktrace is true, it will also have a 'backtrace' key, mapped to the array return value of Throwable::getTrace, but with each element in each frame's "args" array (if set) replaced with the argument's class name (if the argument is an object) or type name (if the argument is a PHP primitive).
Throwable | $e | |
bool | $pretty | Add non-significant whitespace to improve readability (default: false). |
int | $escaping | Bitfield consisting of FormatJson::.*_OK class constants. |
string | $catcher | CAUGHT_BY_* class constant indicating what caught the error |
Definition at line 703 of file MWExceptionHandler.php.
|
static |
Log a throwable to the exception log (if enabled).
This method must not assume the throwable is an MWException, it is also used to handle PHP exceptions or exceptions from other libraries.
Throwable | $e | |
string | $catcher | CAUGHT_BY_* class constant indicating what caught the error |
array | $extraData | (since 1.34) Additional data to log |

static |
Generate a string representation of a stacktrace.
array | $trace | |
string | $pad | Constant padding to add to each line of trace |
Definition at line 423 of file MWExceptionHandler.php.
|
static |
Redact a stacktrace generated by Throwable::getTrace(), debug_backtrace() or similar means.
Replaces each element in each frame's argument array with the name of its class (if the element is an object) or its type (if the element is a PHP primitive).
array | $trace | Stacktrace |
