Paul Joseph Davis commented on COUCHDB-1391:
--------------------------------------------
Just realized the subject of the third patch is silly. Updated on the Git
branch. Too lazy to re upload here for a commit message change.
> Implement _security as _local doc with revision trees

> We had a discussion [1] a while back about updating the _security object so
> that it could be replicated (internally) in a cluster or similar environment.
> The basic gist was "update _local docs to have a revision tree, update
> _security to be a _local doc with docid "_local/_security" and keep the
> current _security API for a version or two for backwards compatibility (or
> forever, what color is your bike shed?)"
> So I did that.
> Basic patch progression is:
> 1. Refactor revision merging logic so that we can split it out of
> couch_db_updater's code path for updating normal docs.
> 2. Implement _local docs with #full_doc_info{} records (and thus revision
> trees)
> 3. Implement _security as _local/_security
> These things are done. Tests should theoretically pass after each patch but I
> haven't gone back and tried. They definitely pass (minus auth_cache which I
> just submitted a fix for) now except for replication.js appears to fail for
> random reasons. I can't quite decide if I've introduced this or if it just
> fails randomly. Rather than run it a lot more times and continue to be
> confused I'm starting this ticket so I can have other people test and tell me
> their results.
> Also, the test suite is rather wonky on trunk with segfaults. We should
> really look into that more.
> Patches forth coming. I've also pushed the branch to [2].
