Zooko and I hammered out a versioning scheme on the mailing list: http://allmydata.org/pipermail/tahoe-dev/2008-November/000879.html has the discussion.

The action items are:

  • add remote_get_version methods to our four main Referenceable objects:
    • storage server
    • introducer server
    • helper
    • chk-upload-helper
  • add web pages for the URLs referenced therein
  • add code to call storage.get_version and stash it somewhere
    • add code to upload to respect max-immutable-share-size
  • add code to introducer client to get_version and require v1
  • add code to helper client to get_version and require v1

Mostly done, in 0eb6b324a4fcda2f, bf06492a90a3cc49, 0fab511be531c6f3, and 3e25efc010876b42. The URLs used as protocol identifiers are:

The version information is attached to the RemoteReference, in the form of a VersionedRemoteReference wrapper with a .version attribute.

The upload code has been modified to look for maximum-immutable-share-size and skip any servers which can't handle the share we want to give them. This still needs tests, though.

89683a39062edc6e adds the test (confirm that the upload code honors maximum-immutable-share-size), so I think we can close this one completely now.
