AnyEvent::Mojo uploaded

Update: uploaded version 0.04, fixes two small things: I was using pre-release 0.8 of Mojo, and apparently I don't know how to use requires in Makefile.PL, causing a stream of CPAN tester failures.

Sebastian Riedel released version 0.7 of his new HTTP stack Mojo (also includes a tiny web-framework called Mojolicious).

The code is very very nice and clean, and in the future you might be able to run Catalyst apps on top of it.

Given that I was looking for a small web framework to run inside my long-lived AnyEvent daemons, I wrote a small glue module to run Mojo-apps using the AnyEvent::Socket/AnyEvent::Handle goodness.

The module is AnyEvent::Mojo, and I've just uploaded release 0.2, that includes keep-alive support.

There are three features that I want to do before a 1.0 release:

• Support for 100 Continue handling: I don't use it but the other Mojo::Server classes have it;
• Asynchronous processing of requests: you start processing a request, but decide that you need something from a network service somewhere. You can start that request, pause the Mojo transaction, and when you receive the response from the network service, you complete the Mojo transaction;
• build a AnyEvent HTTP client using Mojo::Client.

Fun stuff, specially the second one.

Performance-wyse, I'm happy with the result so far. The most simple Mojo::HelloWorld application is capable of this numbers:

# Start a server
perl -MEV -MAnyEvent::Mojo -e 'AnyEvent::Mojo->new->run' &

# Benchmark
ab -k -c 10 -n 5000 http://127.0.0.1:3000/

At 700 requests per second with a 1.3 ms delay, the overhead seems to be pretty low, for a pure Perl based HTTP 1.1 compliant server.
