ASF subversion and git services commented on COUCHDB-2001:
----------------------------------------------------------

Commit 1d3d5bc2bef0233e78ecd83d01dc8e41e2620aae in branch refs/heads/1843-feature-bigcouch
from [~paul.joseph.davis]

Fix bug in erlang views test

This test was incorrectly relying on a bug in the reduce behavior that
would return a reduce value without ever re-reducing it. The fix is to
just correct the test reduce function to behave properly.

> The #leaf{} record change is to enable us to add more data size
> calculations. CouchDB master calculates a data size that account for
> all bytes that are active in a .couch file. Cloudant is interested in
> the total size of uncompressed docs and attachments minus the internal
> overhead of btrees. And there’s a fourth number to calculate based on
> the compression level used. Having each of these numbers will be
> useful as well as the calculations they’ll enable (ie, dead bytes in
> file, bytes used for overhead, compression ratio achieved, etc).
