Subject couch-mrview commit: updated refs/heads/3060-handle-multi-query to 0cc75c1 [Forced Update!]
Date Thu, 25 Aug 2016 03:27:22 GMT
Repository: couchdb-couch-mrview
Updated Branches:
  refs/heads/3060-handle-multi-query c5d9c1a54 -> 0cc75c1db (forced update)


Properly handle multi-query streaming of results

After commit:

https://github.com/apache/couchdb-couch-mrview/commit/3ce28641c85af0d5054df47e9ac7de917a9d33cd

In view_cb if rows came before meta, set the row_sent=true flag did not send
meta after that. That made sense for a single query. However, in case of multiple
queries, which could produce this sequence of callbacks:

meta , row, ... , complete, meta, row, ..., complete

Second meta won't be sent because row_sent flag remains true.

So to fix, make sure to reset row_sent=false in after each complete.
