Apache Etch

Apache Etch is platform, language, and transport layer independent.

This means it works with lots of technologies out of the box and you can focus more of your abilities on writing the code rather then providing target-specific support.

At the core of Etch resides a powerful, custom-built network description language that helps developers describe network services and interactions.

This language is interpreted via the Etch compiler and the framework also comes with various binding libraries for using this language in other programming environments.

Applications built with the Etch framework are highly scalable and provide a high level of efficiency and performance, supporting real-time one or two-way communications.

A network service created via Etch can have a client and server module written in different languages, but still be able to interact and cooperate without any problems regarding message exchange and transport layers.

What is new in version 1.1.0:

• Fixed Bugs:
• UnwantedMessage.ToString method attempts to format using the java style formatting instead of csharp style
• Sometimes closing a TlsConnection normally will result in an IOException with Socket is closed.
• Compiler throws URISyntaxException if there are spaces in the classpath
• Build problems if Etch source is downloaded to a path with spaces
• Incompatibility in the READMEs for the bundled examples
• Windows 7 / .NET 3.5 SP1 runtime setsockopt error
• Improvements:
• TransportFactory.newTransport returns stack topped by DeliveryService which makes it hard to implement meta transports
• Listener stack is built 1/2 upside down and strange inhibiting name service and other transport filters
• Change maven groupId to "org.apache.etch" from "etch.etch"
• New Features:
• Design and implement a framework for interoperability testing, plus a simple demonstration test
• Implement the compiler portion of the c-binding, to generate code for the Etch C runtime
• Integrate the c-binding into the windows build.
• Port the c-binding to linux, resolve differences between windows and linux.
• Implementation of Etch C Binding (Runtime + Compiler)
