nickva opened a new pull request #2617: Handle race condition during concurrent db creation
URL: https://github.com/apache/couchdb/pull/2617
 
 
   Previously concurrent db creation requests could get past db_exists/1 and try
   to create the shard document. The first one would succeed but the others would
   fail with a `500 {"error":"error", "reason":"conflict"}` error instead of
   `412`.
   
   Handle the race condition by checking if db exists after getting a conflict
   error and return a 412 response.
   
   Fixes: #2613
   
   Companion PR to https://github.com/apache/couchdb/pull/2614 which was merge already
