[rc-hackers] Yarp callback threading

[Erik B. <eri...@hi...>]

Dear list,

I'm back with another detailed question regarding Yarp. I have a Yarp
module listening to input messages using BufferedPort::onRead(...). I
noticed that these callbacks are blocking, meaning that the call to
onRead() must finish before the same function can be called again, in
response to the next message. In my implementation, the processing does at
times take too long, meaning that messages will get lost since the
single-threaded calls to onRead are not able to keep up with the phase of
incoming messages.

I would prefer onRead to be called in parallell, for example using an
underlying thread pool. I realize I could of course implement the
threadpool myself, and let each call to onRead distribute new tasks to the
pool, but before I go ahead with this I just wanted to ask if anyone on the
list have a better suggestion, maybe by the use of a different reader.

All best,
