> Hi,
> attached are a series of patches, which add UDP support to Etch for the J=
ava, C# and C bindings. It can be used in place of TCP by replacing the url=
 scheme with UDP. The UDP transport support has been extended with a config=
urable single session mode, which can be used to run leightweight servers. =
Please see the attached file "Leightweight_Etch_Server.txt" for a more deta=
iled description of this mode. It has been written in the confluence wiki s=
tyle syntax and together with the attached images it's suitable for creatin=
g a new etch documentation page. The single session mode has been extended =
further with a support for one-way method calls from the server to multiple=
 clients. For more information, please look at the "Signals" section and th=
e attached patch files.
> The UDP implementation for the C binding is limited to single session mod=
e. It limits the ability of etch servers to call methods of more than one r=
emote client. The signal extension can be used to avoid this limitation.
> Below a short description of the attached patches is listed. They can be =
applied using the following GIT command: "git am -k --keep-cr --whitespace=
=3Dnowarn <path>/*.patch" or can be applied to a clean SVN checkout:  "patc=
h -p1 -i <path>/*.patch".
> * Add property to skip building of the examples:
> 0001-build-add-skip.examples-property.patch
> * Bump dependency to .NET 4.0 and NUnit 2.5.9. The C# UDP implementation =
is based on features available in .NET 4.0.
> 0002-binding-csharp-bump-dependencies-to-.NET-4.0-and-NUn.patch
> * Add runtime and build support for the Mono framework (Mono >=3D 2.10.1,=
 C#).
> 0003-binding-csharp-add-mono-support.patch
> * Make UDP and TCP protocols seamlessly interchangable in Etch (UDP suppo=
rt for C# and Java).
> 0004-binding-csharp-add-udp-transport-support.patch
> 0005-binding-java-add-udp-transport-support.patch
> * Add configurable server single session mode. URL parameter: UdpConnecti=
on.singleSession=3Dtrue
> 0006-binding-csharp-add-udp-single-session-support.patch
> 0007-binding-java-add-udp-single-session-support.patch
> * Add inet_who object to track remote etch clients. Required by the C UDP=
 implementation.
> 0008-binding-c-add-inet_who-object.patch
> * Add UDP transport support to the C binding (single session only). The "=
UdpConnection.singleSession" url parameter is not supported and ignored. A =
patched version of APR (test with version 1.4.2) is required to send broadc=
ast messages under Linux. The patch has been submitted, but is currently no=
t integrated (see https://issues.apache.org/bugzilla/show_bug.cgi?id=3D4638=
9).
> 0009-binding-c-add-UDP-single-session-transport.patch
> * Add signal support for single session mode. See the attached "Leightwei=
ght_Etch_Server.txt" document.

> 0014-binding-c-add-Signal-support.patch
> * Add signal examples for the C#, Java and C binding.
