The returned function appends the error message and extracts

the traceback from `err`.

Example usage:

d.addErrback(log.fail(), 'This is an error message')

Although odd, making the method call is necessary to extract

out useful filename and line number information; otherwise the

reported values are from inside twisted's deferred handling
|

code.

Args:
|
||||
callback: callable to call after making the log. The first argument
|
||||
will be the `err` from the deferred
|
||||
args: extra arguments to pass into `callback`
|
||||
|
||||
Returns: a function that takes the following arguments:
|
||||
err: twisted.python.failure.Failure
|
||||
msg: the message to log, using normal logging string iterpolation.
|
||||
msg_args: the values to substitute into `msg`
|

msg_kwargs: set `level` to change from the default ERROR severity. Other

keywoards are treated as normal log kwargs.
