I've been using multiprocessing managers and I really like the
functionality.
I have a question about reconnecting to a manager. I have a situation
where I start on one machine (A) a manager that is listening and then
on another machine (B) connects to that manager and uses its proxy
object to call functions on the manager's computer; this all works as
expected. But, if the manager from A shuts down, B's application won't
notice because in the MP code it ignores socket error
errno.ECONNREFUSED. If A becomes available again or is restarted, B
doesn't automatically reconnect either and continue its operation.
It's function is basically stopped.
Here is the code from connection.py:
while 1:
try:
s.connect(address)
except socket.error, e:
if e.args[0] != errno.ECONNREFUSED: # connection refused
debug('failed to connect to address %s', address)
raise
time.sleep(0.01)
else:
break
How can I have B automatically reconnect to A and continue its work
once A is available again?
