tonysun83 opened a new pull request #849: Fix external size bug when seq btree exists
URL: https://github.com/apache/couchdb/pull/849
 
 
   ## Overview
   
   When users specify "options":  {"seq_indexed": true}, we will run
   reduced_external_size/1 on seq btrees. The reduce will return an
   integer because the reduce function is:
   couch_db_updater:btree_by_seq_reduce/2.
   This leads to a bad match error. Thanks @jiangphcn for finding this.
   
   ## Testing recommendations
   
   Unit testcase included.
