## Module: `kernel.pbutil`

Utilities for PB using modules.

## Functions

`IPython.kernel.pbutil.``checkMessageSize`()

  Check string m to see if it violates banana.SIZE_LIMIT.

  This should be used on the client side of things for push, scatter and push_serialized and on the other end for pull, gather and pull_serialized.

  Parameters : | m : string Message whose size will be checked. info : string String describing what object the message refers to.
  Exceptions : | PBMessageSizeError: Raised in the message is > banana.SIZE_LIMIT
  Returns: | The original message or a Failure wrapping a PBMessageSizeError

`IPython.kernel.pbutil.``packageFailure`()

  Clean and pickle a failure preappending the string FAILURE:

`IPython.kernel.pbutil.``unpackageFailure`()

  See if a returned value is a pickled Failure object.

  To distinguish between general pickled objects and pickled Failures, the other side should prepend the string FAILURE: to any pickled Failure.
