ASF subversion and git services commented on PROTON-865:
--------------------------------------------------------

Commit 6bef190d4303f818dddfdc4f366ae152dd8cc6fe in qpid-proton's branch 
refs/heads/cjansen-cpp-client from [~aconway]
[ https://git-wip-us.apache.org/repos/asf?p=qpid-proton.git;h=6bef190 ]

PROTON-865: Replace proton_handler with simpler pointer-semantic wrapper 
template.

Template proton::wrapper<pn_foo_t> simply wraps a pn_foo_t*.  Derived classes
such as link, terminus etc. just provide C++ convenience wrapper functions.
Wrappers are passed by value, like pointers, not by reference.

Exception 1: proton::message has value semantics (copy the message) and owns 
it's
pn_message_t* but still provides access to the underlying pointer. Functions
returning a message return a message&.
TODO: return by ref is ugly, needs move semantics on C++11. Arguably should be
a plain wrapper<> and provide value semantics in separate class?

Exception 2: proton::connection - TODO.

> This JIRA tracks initial work on a C++ binding to the Proton reactor event 
> based model with an eye to providing an API very similar to the python 
> client.  As stated on the Proton list, the broad goals are:
>   to make it easy to write simple programs
>   natural to build out more complicated ones
>   very similar API to the Python client
>   lean and performant
> The initial introduction with accompanying HelloWorld can be found at
>   https://github.com/apache/qpid-proton/pull/18
> Ongoing work is proceeding in my github account in branch cpp-work
>   https://github.com/cliffjansen/qpid-proton/tree/cpp-work
> commit 1453f57ca3f446450ef654505548f1947cb7a0f1 adds listener support, 
> exceptions and a logging interface.
> The initial implementation will provide no thread safety guarantees, but the 
> bone structure should allow that to be added later with no API change.  I 
> still hold out hope of eventually allowing multiple threads processing 
> separate connections concurrently.
