JSON::RPC2 - Transport-independent implementation of json-rpc 2.0
This document describes JSON::RPC2 version 0.2.1
This module implement json-rpc 2.0 protocol in transport-independent way. It was very surprising for me to find on CPAN a lot of transport-dependent implementations of (by nature) transport-independent protocol!
Also it support non-blocking client remote procedure call and both blocking and non-blocking server method execution. This can be very useful in case server methods will need to do some RPC or other slow things like network I/O, which can be done in parallel with executing other server methods in any event-based environment.
There a lot of other RPC modules on CPAN, most of them has features doesn't provided by this module, but they either too complex and bloated or lack some features I need.
Not transport-independent. Do eval() of perl code received from remote server.
Not transport-independent. Not event-loop-independent.
Not transport-independent. Blocking on remote function call.
In theory it's doing everything... but I failed to find out how to use it (current version is 0.05) - probably it's incomplete yet. Even now it's too complex and bloated for me, I prefer small and simple solutions.
CONFIGURATION AND ENVIRONMENT
JSON::RPC2 requires no configuration files or environment variables.
BUGS AND LIMITATIONS
- Batch/Multicall feature
Not supported neither in Server nor in Client.
It may be cool to have parallel request processing allowed in spec using event-based style. But this feature doesn't looks really useful so it implementation delayed until it become clear it's needed to avoid needless complexity.
No bugs have been reported.
