This is a fork of the stdlib net/rpc which
is frozen. It adds support for context.Context on the client and server,
including propagating cancellation.
The API is exactly the same, except Client.Call takes a context.Context,
and Server methods are expected to take a context.Context as the first
argument. Additionally the wire protocol is unchanged, so is backwards
compatible with net/rpc clients.
DialHTTPPathTimeout function is also added. A future release of rpc may
update all Dial functions to instead take a context.
ClientTrace functionality is also added. This is for hooking into the rpc
client to enable tracing.
There are many alternatives for RPC in Go, the most popular being
GRPC. However, net/rpc has the following nice
properties:
- Nice API
- No need for IDL
- Good performance
The nice API is subjective. However, the API is small, simple and composable.
which makes it quite powerful. IDL tools are things like GRPC requiring protoc
to generate go code from the protobuf files. net/rpc has no third party
dependencies nor code generation step, simplify the use of it. A benchmark
done on the 6 Sep
2016
indicated net/rpc was 4x faster than GRPC. This is an outdated benchmark,
but is an indication at the surprisingly good performance net/rpc provides.
For more discussion on the pros and cons of net/rpc see the issue proposal:
freeze net/rpc.

Cancellation implemented via the rpc call _goRPC_.Cancel.
