Hi !
Another issue I have to deal with is the polling (update_meta()
function) should not happen place until the stream connection is not
established or under error.
First case I think of:
x = insert_metadata(s0)
insert = fst(x)
s = snd(x)
delay = ref 5. #default poll interval
output = out(on_disconnect={ delay := (-1.) }, on_connect={ delay :=
(5.) } ...... , s) # I could add on_error here too
def update_meta() =
path = get_source(output) # I need the source "output" here
(...)
!delay
end
add_timeout(0.; update_meta)
Pro's: polling is stopped when needed.
Problem:
- I can't start the poll anymore when the connection comes up gain.
(on_connect with new positive delay is useless as add_timeout stopped).
Note: on_disconnect is not called on initial connection failure.
("disconnect" implied by "connection had success before"). So I solved
that by defining on_error but the first problem remains.
So I've think to put add_timeout() call directly in on_connect
definition but it's not possible as update_meta() can't be defined
before output source.
What do you think I could do ?
