ASF subversion and git services commented on COUCHDB-523:
---------------------------------------------------------

Commit 3015c8554ae38fc3fa7890209c5e394e5995e1c8 in couchdb-couch-mrview's branch refs/heads/1993-bigcouch-couch-mrview from [~chewbranca]
[ https://git-wip-us.apache.org/repos/asf?p=couchdb-couch-mrview.git;h=3015c85 ]

Add support for multi query views

This adds support for making multiple view queries in one request by
supplying a "queries" list in a POST request body. The primary
implementation was ported over from chttpd_view:multi_query_view/5.

The support added here is two fold. First, we add multi_query_view
support to the single node interface in couch_mrview_http. Second we
add support in couch_mrview_http:view_cb/2 to allow chttpd to utilize
this callback as well.

This also switches updates the #vacc record from setting a multi_query
flag, to instead setting a should_close flag. Now
couch_mrview_http:view_cb/2 will only start a new delayed response if
#vacc.resp is undefined, and similarly, it will only close a delayed
response if #vacc.should_close is true.

> It would be useful if I could do a single POST to a view to retrieve multiple ranges specified by startkey, endkey.
> The format could be as follows:
> { "ranges": [ { "startkey": "a", "endkey": "c" }, { "startkey":"g", "endkey":"z" } ] }
