When installed, this provides the - 'allmydata' package. This includes a few pieces copied from - the PyCrypto package, in allmydata/Crypto/* . - -Within src/allmydata/ : - - interfaces.py: declaration of zope.interface-style Interfaces for most - components, also defines Foolscap RemoteInterfaces for - all remotely-accessible components - - node.py: the base Node, which handles connection establishment and - application startup - - client.py, introducer.py: - these are two specialized subclasses of Node, for users and the central - introducer, respectively. Each works by assembling a collection of services - underneath a top-level Node instance. - - introducer.py: node introduction handlers, client and server - - storageserver.py: provides storage services to other nodes - - codec.py: low-level erasure coding, wraps the zfec library - - encode.py: handles turning data into shares and blocks, computes hash trees - - upload.py: upload server selection, reading data from upload sources - - download.py: download server selection, share retrieval, decoding - - dirnode2.py: implements the distributed directory nodes. - - webish.py, web/*.xhtml: provides the web frontend, using a Nevow server - - uri.py: URI packing/parsing routines - - hashtree.py: Merkle hash tree classes - - debugshell.py, manhole.py: SSH-connected python shell, for debug purposes - - util/*.py: misc utility classes - - test/*.py: unit tests - - -Both the client and the central introducer node runs as a tree of -(twisted.application.service) Service instances. The Foolscap "Tub" is one of -these. Client nodes have an Uploader service and a Downloader service that -turn data into URIs and back again. - -The Uploader is given an "upload source" (which could be an open filehandle, -a filename on local disk, or even a string), and returns a Deferred that -fires with the URI once the upload is complete. The Downloader is given a URI -and a "download target" (an open filehandle, filename, or instructions to -provide a string), and fires a Deferred with a target-specific value when the -download is complete. The source/target API is intended to make it easy to -stream the incoming data to a media player or HTTP connection without having -to consume a lot of memory for buffering. -
