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.
|
|
|
|
.. 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.
|
|
