MUSCLE

MUSCLE (Multi User Server Client Linking Environment) is an N-way messaging server and networking API. It includes client-side networking APIs for various languages, including C, C++, C#, Delphi, Java, and Python. MUSCLE lets programs communicate over a network via streams of serialized Message objects. The included server program ("muscled") lets its clients message each other and store information in its server-side hierarchical database. The database supports flexible queries via hierarchical wildcarding, and "live" updates via a subscription mechanism.

  •  04 Feb 2012 05:37

    Release Notes: Minor bugs were fixed. Memory usage of the Message class was reduced a bit, better control over the zlib-encoding of outgoing compressed Message objects was provided, and a deprecated Queue method was removed (GetItemPointer()).

    •  06 Jan 2012 21:47

      Release Notes: This version adds a couple of gateway subclasses that keep track of the number of bytes currently in their output queues, adds a couple of additional callbacks to the ReflectServer class, and fixes a couple of minor bugs.

      •  23 Dec 2011 13:38

        Release Notes: This release adds two more implementations of the SocketMultiplexer class, one based on BSD's kqueue()/kevent(), and another based on Linux's epoll().

        •  14 Dec 2011 03:17

          Release Notes: This release adds a SocketMultiplexer class which hides the details of select() and poll() behind a simpler and more consistent API. It also fixes a bug in Message::FindFlat() which could cause it to return incorrect results when called on locally-created Messages containing FlatCountableRef-referenced objects.

          •  02 Dec 2011 03:02

            Release Notes: This release adds optional support for basing the ReflectServer event loop around poll() instead of select. It also makes the socket-pair in the Thread class optional, adds a couple of new methods to the Queue class, and makes the multicast API enabled by default.

            You need to add QueryFilter.o and ByteBuffer.o to the Makefile to get it to compile with latest MUSCLE's.

            New version of Clyde is v1.04. It's
            been tweaked to compile with MUSCLE v1.30+.

            Confusing name
            The name of this project is rather confusing. MUSCLE is already the name of the de-facto standard smartcard environment for Linux. (Google for "muscle linux" and you'll see what I mean.)

            Clyde 1.01 is
            here. It fixes a nasty crashing bug and adds a few minor features.
