tonysun83 opened a new pull request #3150:
URL: https://github.com/apache/couchdb/pull/3150


   This fixes a94e693f32672e4613bce0d80d0b9660f85275ea because a race
   condition exisited where the 'DOWN' message could be received
   before the compactor pid is spawned. Adding a synchronous call to
   get the compactor pid guarantees that the couch_db_updater process
   handling of finish_compaction has occurred.

        Also remember, that CouchDB uses the Review-Then-Commit (RTC) model
        of code collaboration. Positive feedback is represented +1 from committers
        and negative is a -1. The -1 also means veto, and needs to be addressed
        to proceed. Once there are no objections, the PR can be merged by a
        CouchDB committer.
