Undocumented

(type: int)

def format_frames(frames, write, detail="""default"""): (source)

Format and write frames.

Parameters	frames	is a list of frames as used by Failure.frames, with each frame being a list of (funcName, fileName, lineNumber, locals.items(), globals.items()) (type: list)
	write	this will be called with formatted strings. (type: callable)
	detail	Four detail levels are available: default, brief, verbose, and verbose-vars-not-captured. `Failure.printDetailedTraceback` uses the latter when the caller asks for verbose, but no vars were captured, so that an explicit warning about the missing data is shown. (type: string)

EXCEPTION_CAUGHT_HERE =

Undocumented

(type: str)

def _Traceback(stackFrames, tbFrames): (source)

Construct a fake traceback object using a list of frames. Note that although frames generally include locals and globals, this information is not kept by this method, since locals and globals are not used in standard tracebacks.

Parameters	stackFrames	[(methodname, filename, lineno, locals, globals), ...]
	tbFrames	[(methodname, filename, lineno, locals, globals), ...]

_inlineCallbacksExtraneous =

Undocumented

(type: List)

def _extraneous(f): (source)

Mark the given callable as extraneous to inlineCallbacks exception reporting; don't show these functions.

Parameters	f	a function that you NEVER WANT TO SEE AGAIN in ANY TRACEBACK reported by Failure. (type: function)
Returns	f

def _safeReprVars(varsDictItems): (source)

Convert a list of (name, object) pairs into (name, repr) pairs.

twisted.python.reflect.safe_repr is used to generate the repr, so no exceptions will be raised by faulty __repr__ methods.

Parameters	varsDictItems	a sequence of (name, value) pairs as returned by e.g. `locals().items()`.
Returns	a sequence of (name, repr) pairs.

DO_POST_MORTEM =

Undocumented

(type: bool)

def _debuginit(self, exc_value=None, exc_type=None, exc_tb=None, captureVars=False, Failure__init__=Failure.__init__): (source)

Initialize failure object, possibly spawning pdb.

def startDebugMode(): (source)

Enable debug hooks for Failures.
