ASF GitHub Bot commented on COUCHDB-2863:
-----------------------------------------
Github user nickva commented on the pull request:
https://github.com/apache/couchdb-fabric/pull/47#issuecomment-213864498
+1
Verified this along with https://github.com/apache/couchdb-couch/pull/166
and https://github.com/apache/couchdb-couch/pull/167
Don't fully understand this code (if that is a hard requirement for +1-ing
then disregard this). However checked EUnit tests pass, saw new ones in fabric
and couch, those pas, and most importantly verified function_clause error from
https://issues.apache.org/jira/browse/COUCHDB-2863 doesn't happen anymore (they
still happen on master as Jira issue describes).

Deleting the doc and getting latest works as expected as well:
```
$ http delete
http://adm:pass@localhost:15984/db/doc?rev=2-7051cbe5c8faecd085a3fa619e6e6337
{
"id": "doc",
"ok": true,

}
