.. _version-1.1.2:

:release-date: 2016-09-07 04:18 P.M PDT :release-by: Ask Solem

• barrier: now handles the case where len(promises) returns NotImplemented.

.. _version-1.1.1:

:release-date: 2016-06-30 12:05 P.M PDT :release-by: Ask Solem

• Requirements: Tests now depends on :pypi:case 1.2.2

• Five: python_2_unicode_compatible now ensures __repr__ returns bytes on Python 2.

.. _version-1.1.0:

• promise.throw() now passes partial args/kwargs to the errback:

  >>> p = promise(args=(self,), on_error=handle_error)
  >>> p.throw(exc)  # --> handle_error(self, exc)

• New vine.abstract.ThenableProxy can be used to add promise-capabilities to a class by forwarding to a different promise.

  from vine import promise
  from vine.abstract import ThenableProxy
  
  class P(ThenableProxy):
  
      def __init__(self, on_success=None, on_error=None):
          self._set_promise_target(promise(
              args=(self,), callback=on_success, on_error=on_error,
          ))
  
  p = P()
  p.then(download_file(url)).then(extract_file)

• promise.throw() now supports a propagate argument that can be set to False to never reraise the exception.

• promise.throw() now also reraises the current exception from the stack, if the exc argument is passed and that value is the same as the current exception.

• Thenable.register() can now be used as a decorator.

• Argument to promise.throw1(exc) can now be None to use the current exception.

• monotonic() now uses librt.so.0 as an alternative if librt.so.1 does not exist.
