I'm pleased to announce the release of Foolscap-0.0.2 . (What is 'foolscap', you ask? Good question. It is a size of paper, or the hat worn by a court jester, or a distributed object-capability protocol for Twisted. Only the first two definitions show up in wikipedia, however.) newpb has been moved out of the Twisted SVN subdirectory into a new top-level package where it can be developed independently of the Twisted release cycle. (see ticket #1999 for details). In the process it has been renamed to "Foolscap". (this name has some good properties, but "rolls pleasantly off the tongue" is not one of them, and I'm not completely settled on it yet, so don't be surprised if the name changes again in the next couple of months). Foolscap is the next-generation version of Twisted's native RPC protocol, the venerable Perspective Broker. It lets you make certain methods of certain objects on one machine invokable from other machines. Foolscap (aka newpb) has been in development on and off for, um, years, and is starting to be ready for brave adventurers to give it a spin. Incompatible protocol and API changes are likely to come, so keep in mind that it is not yet suitable for production deployment. The 0.0.2 release does not make any significant behavioral or protocol changes relative to the earlier 0.0.1 release, but it does change the package name and rearranges the preferred entry point. In 0.0.1 you needed to import a number of second-level modules to use newpb (i.e. 'from twisted.pb import pb; tub = pb.PBService()'). In 0.0.2 the foolscap/__init__.py file contains all the important entry points, so you just do 'from foolscap import PBService'. The newpb (aka foolscap) wiki page contains lots of information about what sorts of new features foolscap has relative to PB, links to view the source and protocol specifications, and of course the download tarball: http://twistedmatrix.com/trac/wiki/FoolsCap The release itself is available in my home directory on pyramid: http://twistedmatrix.com/~warner/Foolscap/ The source code lives in Twisted SVN in the sandbox: svn://svn.twistedmatrix.com/svn/Twisted/sandbox/warner/Foolscap/trunk For a quick taste of what it looks like to make objects remotely available via Foolscap, take a look at the simple client+server examples in the docs: http://twistedmatrix.com/trac/browser/sandbox/warner/Foolscap/trunk/doc/list... http://twistedmatrix.com/trac/browser/sandbox/warner/Foolscap/trunk/doc/list... Please grab the release and give it a whirl. The more people who use it, the better ideas we'll get about where it needs to go and what development still needs to be done. The docs have a number of files describing the protocol work that remains to be finished, but usability and practical deployment issues are the biggest unknowns right now, and the only way to figure those out is to actually use it for something. share and enjoy, -Brian
