Background + + Directory authorities use the "consensus method" mechanism to achieve + forward compatibility during voting. When each authority publishes + its vote, it includes a list of numbered consensus methods that it + supports. Each authority chooses to calculate the consensus + according to the highest consensus method it knows supported by more + than 2/3 of the voting authorities. So long as all the authorities + have a method in common, they will all reach the same consensus. + + Consensus method 1 was first introduced in the Tor 0.2.0 series + around 2008. But by 2012, we realized that we had a problem: we were + stuck documenting and supporting old consensus methods indefinitely. + + With proposal 215, we deprecated and removed support for all + consensus methods before method 13. That was good as far as it went, + but it didn't solve the problem going forward: the latest consensus + methods is now 28. + + This proposal describes a policy for removing older consensus methods + going forward, so we won't have to keep supporting them forever. + +2. Proposal + + I propose that from time to time, old consensus methods should be + deprecated. + + Specifically, I propose that we deprecate all methods older than the + highest method supported in first stable release of the oldest LTS + (long-term support) release series. + + For example, the current oldest LTS series is 0.2.5.x. The first + stable release in that series was 0.2.5.10. The highest consensus + method listed by 0.2.5.10 is 18. Therefore, we should currently + consider ourselves free to deprecate all methods before 18. + + Once 0.2.5.x is deprecated, 0.2.9.x will become the oldest LTS + series. The first stable release in that series was 0.2.9.8. The + highest consensus method listed by 0.2.9.8 is 25. Therefore, once + 0.2.5.x is deprecated (in May 2018), we may deprecate all methods + before 25. + + When a consensus method is deprecated, it should no longer be listed + or implemented by the latest Tor releases. (It's okay for older + authorities to keep advertising it.) + + Most consensus methods add a feature that is used in "method M or + later". Deprecating method M-1 means that the feature is used in all + supported consensus methods. Therefore, we can remove any code that + makes the feature conditional on a consensus method, and any code for + previous implementations of the feature. + + Some consensus methods remove a feature that was used up to method + N. Deprecating method M means that the feature is no longer used by + any supported consensus methods. Therefore, we can remove any code + that implements the feature. + +A. Acknowledgments + + Thanks to isis and teor for the discussion that led to this proposal. + I believe that teor first suggested the policy described in section 2 + above. + +B. Client and relay compatibility notes + + Dear reader: you may be worrying that this proposal will cause old + clients or relays to stop working prematurely. That is not the case. + Consensus methods determine how the authorities behave, but they do + not represent backward-incompatible changes in how they generate + their consensuses. +
