All,
I'm currently playing with mojolicious for a prototype project and I like
what I see. Apologies if my terminology is off, I'm still learning mojo:)
I've started to explore the idea of using mojo to replace some of our
legacy embedded web based technologies and for a future embedded REST API,
but I am struggling with how to integrate it to our event based back end.
Specifically on how to generate an event from within Mojo::IOLoop. I know I
can use a timer based approach, ie, wake up every second to see if an event
has arrived, but it's not ideal for various reasons.
The application itself is a C/XS based, and spawns a thread that runs perl
code to provide a web based UI and API to monitor/control the application.
Some of the older stuff is based on HTTP::Daemon while some of the newer
stuff handles websockets based on Protocol::WebSocket so it's all low level
and mojolicious would excel as a replacement.
Many of the requests would block for a variety of reasons (ie, the response
takes time) and the way we handle this is to have the perl code sitting on
a select (IO::Select) statement which handles the raw websocket connection
and a socket connection from inside our app. If a message is received on
this app socket, we then read from our event message queue, process it and
send it down the websocket. For the most part, this works well and results
in mostly none blocking operation.
I believe I can use the same approach of using a socket from the thread
running mojo to the app, but I am unsure how to create this socket and
associated it to Mojo::IOLoop to get callbacks etc?
Is this raw socket approach the best solution, or are there other ways to
get Mojo::IOLoop to wake up on an 'external event'?
Thanks,
