Git allows anyone to try to push, and then +check whether it is ok before finally accepting it. Monotone has no way to accept or reject revisions +in this way. However, monotone does have the ability to mark revisions, and to ignore unmarked revisions. + +This marking capability can be used to achieve a somewhat similar effect to what happens with git. The +problem with this is that anyone could put anything into the monotone database, and while this wouldn't +affect ikiwiki, it seems bad to leave open, untrusted storage on the web. + +The Plan +===== + +In the `note_netsync_revision_received` hook in the monotone server, have the server check to make sure +that either a) the revision is signed by someone trusted or, b) the revision is checked using the same +hook that git uses in `pre-receive`. If the revision passes the ikiwiki `pre-receive` check then the +monotone hook signs the revision. This gives that revision the 'ikiwiki seal of approval'. + +You'll also want to update the monotone trust hooks to only trust revisions signed by trusted people, or +ikiwiki. + +Now anyone can upload a revision, but only those signed by a trusted person, or which pass the ikiwiki +check and so get signed by the ikiwiki key, will be seen by ikiwiki.
