+1 to what Chad said reg deploy and what Toby, Chad & Scott said with
their kudos and appreciation :) -Subbu.

I love working with smart folks.

Considering the code just landed last night and a good number of us are
going to be gone for vacation--is rolling this out with the Jan 2nd deploy
a little aggressive? I'd love to see this sit on beta (with eyes on it) for
a little longer. Or a way to deploy to testwiki etc independent of major
sites?
The first deploy after a holiday break is already pretty exciting, and
rolling this out feels like something that could use a dedicated window.
(Otherwise, kudos to the MCR team for hitting this milestone)

Hello all!
Addshore last night merged the patch[1] that is the first major step
towards
Multi-Content-Revisions[2]: it completely guts the Revision class and
turns it
into a thin proxy for the new RevisionStore service. The new code is now
live
on beta.
This is our second attempt: The first one, on December 18th, thoroughly
corrupted the beta database. It took us some time and a lot of help from
Aaron
and especially Roan to figure out what was happening. A detailed
post-mortem by
Roan can be found at [3].
Anyway - this stage of MCR development introduces the new multi-revision
capable
interface for revision storage (and blob storage) [4]. It does not yet
introduce
the new database schema, that will be the next step [5][6]. While doing
the
refactoring, I tried to keep the structure of the existing code mostly
intact,
just moving functionality out of Revision into the new classes, most
importantly
RevisionRecord, RevisionStore, and BlobStore.
Beware that with the next deployment (due January 2nd) the live sites
will
start
using the new code. Please keep an eye out for any strangeness regarding
revision handling. Adam greatly improved test coverage of the relevant
code
(thanks Adam!), but it's always possible that we missed some edge case,
maybe
something about archived revisions that were partially migrated from on
old
schema or something similarly fun.
Exiting times!
Cheers
Daniel
