Documentation

The Basics

• architecture.txt, explaining the design decisions that have given the grid its current shape
• roadmap.txt, showing how the functionality has been incrementally improved so far, and what improvements we plan to make next
• codemap.txt, laying out the software design and the organization of the source code
• UseCases, enumerating the ways in which Tahoe should be usefula

The Parade of Release Notes

• the release notes announcing the first public release on May 2, 2007 and giving a general overview of why the Tahoe project exists
• the release notes announcing the second public release on June 6, 2007
• the release notes announcing the third public release on June 29, 2007, including the new mutable, shareable, private directories

Detailed Design Docs

• TahoeIssues/FileTree?, explaining how mutable, shareable, private directories are implemented (which requires interesting crypto)
• TahoeIssues/FileEncoding?, explaining how we turn files into shares, with verifiable hashes; This is mostly concerned with chunking and Merkle trees.
• TahoeIssues/ShareEncoding?, explaining how we turn a chunk into shares: Reed-Solomon, FEC, that stuff

Outstanding Issues

• PeerSelection, explaining how a Tahoe node chooses which other nodes to use for uploading and downloading files (which raises some unsolved issues in balancing scalability, robustness, performance, and simplicity)
• TahoeIssues/ChangingFilesWhileCopyingThem? : what are the semantics of the "upload" action? the upload takes non-zero time: what happens if the file is changed during that time?
