I think this has been discussed before, but is there a consensus on
what C++ version we want to target for the C++ binding? C++03 is old
and smelly. C++11 is better, C++14 better still and afaik any compiler
that does 11 will do 14. So the sensible choices would seem to be:
1. Smelly C++03 code on

I would like to create a separte git repo for the proton Go binding.
Go provides "go get" to grab online go source libraries, based on
cloning repos. The go tools assume that each go project has its own

Good point, I'll ask around and on infra, I may be missing something.
If anyone's interested in brainstorming about the proper way to do this

C++ tutorial is mostly done, if that interests you
http://people.apache.org/~aconway/proton/
or check out cjansen-cpp-client.
I'm documenting the C++ binding but the proton C reactor.h is very
light on documentation. Is anyone working on this? I'm figuring it out
from source but it would be good to have some docs there.

I don't see any pn_message_copy function in the proton library, is
there an efficient way to make an independent copy of a message? I can
encode and decode but that seems like a long way around.

need a sanity check.

well as some tests to verify that we get compile errors to preve

I'll do you one better - C++ can use *either* (or boost
shared/intrusive pointers) seamlessly if we say that all C++ smart
pointers own a *proton reference*, not a *proton object*.
Will have another proposal out shortly to clarify.

Here's the API doc, the code is coming. It is like previous proposals
which were well received but more correct. It has *two* conversion

The "use python to drive C and Java tests" was a good idea at the time

There are two things we need:

I have been reminded that we actually had a discussion and put together

I probably agreed to this at the
I've pushed the Go binding to master, read all about it at
https://github.com/apache/qpid-proton/blob/master/proton-c/bindings/go/

The documentation needs a lot of work but you can check the examples
and start playing with the code now.
Please ignore the packages go/amqp, go/messaging

I'm fiddling with the C++ example broker, and when I install a debug

is a PN_REACTOR_QUIESCED event about every 3 seconds. Does anybody know

The proton reactor provides a complete solution for integrating foreign
IO into a single threaded proton event loop. This is useful in
situations where proton is being used in isolation, there is no other
IO handling framework available and everything is single threaded.
However often that is not
The Go binding for proton provides 2 alternate APIs, `proton` is an
exact analogue of the event-driven proton C API and `electron` which is
a more go-oriented, procedural API. The differences were motivated by
the concurrency features of the Go language but there may be lessons to
learn for other l

Node "1" is the first child node (node 0 is the "root" of the tree).
Nodes are referred to by number rather than pointer because the node
storage can be re-allocated if the pn_data object grows which changes
the node addresses. So
