:no_proc errors when GenStage finishes quickly
simonmcconnell opened this issue · comments
Similar to #88.
Flow 1.2.0
GenStage 1.1.2
Elixir 1.13.3
Erlang 24.3
My Flow looks something like this, where my spec is only options that are for internal business.
Flow.from_specs([{Producer, spec}])
|> Flow.partition(key: {:key, :time})
|> Flow.reduce(fn -> [] end, fn apple, similar_apples ->
...
end)
|> Flow.run()and the producer does this:
def start_link(opts) do
GenStage.start_link(__MODULE__, opts, name: via(opts))
end
def init(opts) do
...
if nothing_to_do, do: GenStage.async_info(pid, :terminate)
{:producer, state}
end
def handle_info(:terminate, state) do
{:stop, :shutdown, state}
endOriginally, I was returning :ignore in init/1 or {:stop, :normal, state} in handle_demand if there was nothing to do/it ran out of demand. All gave the same error.
I added a sleep, and it works.
Task.start(fn ->
Process.sleep(5000)
GenStage.async_info(pid, :terminate)
end)Am I missing something or should this work without adding the stop delay?

Yes, there will always be a race if the producer can terminate before the consumers even subscribe. If you start the producer, then it will be expected for it to allow the pipeline to establish. Another option is for us to support returning :ignore from init and then change Flow to deal with it accordingly and without starting the rest.
No worries. Handling :ignore would help but there is always the chance of exiting from handle_demand before the rest have subscribed. I might try keeping a stage on hand, warmed up and ready to go.
Is there a way to detect that all the consumers have subscribed?
A PR that supports :ignore, if not supported yet, would be welcome then!
If you know the number of partitions next, then you can count the number of times handle_subscribe is called.
Ok, I'll look into it.
I partition on time over spans of day/week/month, so I don't think that will work for my use case.
@josevalim do you think it will be possible to handle the other case, where the demand is exhausted and the producer stops before all the workers are subscribed? Or would I be wasting my time trying?
It should be possible if:
- you know how many consumers will be subscribing
- you can uniquely tag each subscription
- you are sure all consumers will eventually subscribe
Even then, there may be corner cases.
