Signals
=======
:ref:`Please refer to Signals <signals>`.
Mitogen contains a simplistic signal mechanism to decouple its components. When
a signal is fired by an instance of a class, functions registered to receive it
are called back.
.. warning::
As signals execute on the Broker thread, and without exception handling,
they are generally unsafe for consumption by user code, as any bugs could
trigger crashes and hangs for which the broker is unable to forward logs,
or ensure the buggy context always shuts down on disconnect.
Functions
---------
.. currentmodule:: mitogen.core
.. autofunction:: listen
.. autofunction:: unlisten
.. autofunction:: fire
List
----
These signals are used internally by Mitogen.

Signals
=======
Mitogen contains a simplistic signal mechanism to help decouple its internal
components. When a signal is fired by a particular instance of a class, any
functions registered to receive it will be called back.

they are generally unsafe for consumption by user code, as any bugs could
