devel/py-tblib 3.2.2 FreeBSD

Serialization library for Exceptions and Tracebacks.

It allows you to:

• Pickle tracebacks and raise exceptions with pickled tracebacks in different processes. This allows better error handling when running code over multiple processes (imagine multiprocessing, billiard, futures, celery etc).
• Create traceback objects from strings (the from_string method). No pickling is used.
• Serialize tracebacks to/from plain dicts (the from_dict and to_dict methods). No pickling is used.
• Raise the tracebacks created from the aforementioned sources.
• Pickle an Exception together with its traceback and exception chain (raise ... from ...) (Python 3 only)

Again, note that using the pickle support is completely optional. You are solely responsible for security problems should you decide to use the pickle support.
