Dev

Views into the process of Tahoe-LAFS hackery.

• The Roadmap page (linked at the top of each page) shows the next planned release and what improvements and bugfixes we are working on.
• The User Doc page

Source Code (via revision control)

• Darcs checkout:

darcs get --lazy https://tahoe-lafs.org/source/tahoe-lafs/trunk tahoe-lafs

• ​git checkout (EXPERIMENTAL!) announced here:

git clone git://github.com/warner/tahoe-lafs.git

Community

• The tahoe-dev mailing list is the community forum for discussion of Tahoe-LAFS design, implementation, and usage.
• Tahoe-LAFS hackers chat on ​irc.freenode.net in channel #tahoe-lafs. This channel is archived at ​http://fred.submusic.ch/irc/tahoe-lafs/ .
• The CREDITS file​ contains names people who have contributed to the Tahoe-LAFS project.
• The RelatedProjects page has extensions to Tahoe-LAFS and integrations of Tahoe-LAFS with other open source software.

Extensions

• Tahoe-LAFS has a programmatic API which enables building custom applications on top of the storage infrastructure.
• The docs/frontends/webapi.rst​ document shows how to control a Tahoe-LAFS node programmatically over HTTP.
• The Extension Page has some additional tips on how to use the web-API.

Developer Docs

Design of the System

• ​TahoeLAFSBasics on the Nilestore Project's site. This document was written by someone from another project who hasn't really interacted with the Tahoe-LAFS developers much, but it is the best overall introduction to the design of Tahoe-LAFS.
• after that, look at the "Presentations / Papers", below, or at the "architecture.rst" file in the docs/ directory.

Presentations / Papers

• trac/tahoe-lafs/attachment/wiki/News/tahoe-RSA-slides.pdf presented at RSA 2010
• Tahoe – The Least-Authority Filesystem presented at ​Storage Security and Survivability '08
• Tahoe: A Secure Distributed Filesystem presented at ​PyCon2008, providing an overview of the Tahoe-LAFS design, and the slides (.zip) that were used for the presentation
• ​A Performance Evaluation and Examination of Open-Source Erasure Coding Libraries For Storage to be presented at ​FAST-2009: 7th USENIX Conference on File and Storage Technologies

Papers By Others About Tahoe-LAFS

• ​Cloud Storage Vault—Master's Thesis by Haver, Melvold, Ruud

Cool New Ideas We're Working On

• Ostrom is about how social networking and economics interact with distributed storage
• OneHundredYearCryptography

More Details To Look Up While Working On Your Contribution

• the docs/ directory <-- most core doc is in the source tree here
• Capabilities: what are readcaps and writecaps and verifycaps, etc
• The Packaging page shows our current policy for how to re-use 3rd-party libraries and how to distribute Tahoe-LAFS to users.

Tools

• tahoe-lafs-trac-stream mailing list is the way to receive lots of emails from trac

• ViewTickets
• Sources for Tahoe-LAFS and its side-projects are browsable via the "Browse Source" button at the top of each project site
• there is an experimental git mirror of the darcs repository (not necessarily up-to-date) ​on github.
• https://source/tahoe-lafs/tarballs contains snapshots of current source code.
• The Buildbot page (linked at the top of each page) shows current build and test results. See the BuildbotPolicy page and HowtoContributeABuildbot page.
• The Timeline (linked at the top of each page) shows changes to the source code, the issue tickets, and the wiki (i.e. this web site).
• The code coverage statistics show which lines of code get exercised by the unit tests.
  • Archived data is also available.
  • This graph measures the number of lines that are not covered.

Dependencies

• Copies of libraries that Tahoe-LAFS is dependent on are at source/tahoe-lafs/deps/.
• The tahoe-dep-eggs subdirectory has precompiled "egg" packages (scroll to the bottom for a matrix of platforms and Python versions for each package).
