nickva opened a new pull request #1277: In _scheduler/docs fix `crashing` state showing as `pending` sometimes
URL: https://github.com/apache/couchdb/pull/1277
 
 
   Replication jobs are backed off based on the number of consecutive crashes,
   that is, we count the number of crashes in a row and then penalize jobs with an
   exponential wait based that number. After a job runs without crashing for 2
   minutes, we consider it healthy and stop going back in its history and looking
   for crashes.
   
   Previously a job's state was set to `crashing` only if there were any
   consecutive errors. So it could have ran for 3 minutes, then user deletes the
   source database, job crashes and stops. Until it runs again the state would
   have been shown as `pending`. For internal accounting purposes that's correct
   but it is confusing for the user because the last event in its history is a
   crash.
   
   This commit makes sure that if the last even in job's history is a crash user
   will see the jobs as `crashing` with the respective crash reason. The
   scheduling algorithm didn't change.
   
   Fixes #1276
