  • 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.
