Are gevent.spawn_link_exception and friends gone in gevent v1.0 permanently?

[vitaly]

I tried to switch my app from gevent 0.13.x to v1.0b2 and found a few
things to be missing:

gevent.spawn_link_exception
gevent.greenlet.LinkedFailed and friends


Also, Greenlet.link_exception(self, receiver=None,
SpawnedLink=FailureSpawnedLink) provides a default value for receiver,
but raises an exception if called without a receiver:

>>
/Users/vkruglikov/Packages/gevent-1.0b2/gevent-1.0b2/build/
lib.macosx-10.7-intel-2.6/gevent/greenlet.pyc in __init__(self,
callback)
20 def __init__(self, callback):
21 if not callable(callback):
---> 22 raise TypeError("Expected callable: %r" %
(callback, ))
23 self.callback = callback
24
<<

Thank you,
Vitaly

Yes, "linking to greenlet" feature was removed in 1.0.

Is there a way to accomplish the same functionality, without
subclassing Greenlet?

Sure, just pass a callable to link() that will kill() your greenlet.

one_greenlet.link(lambda *args:
another_greenlet.kill(Exception('one_greenlet is dead'))

However, using kill() and asynchronous exceptions in general is not
recommended. Best to structure your program differently so you don't
need it.
