  - Merge branch 'stable-3.5' into stable-3.8
    
    * stable-3.5:
      TasksStorage: Remove synchronized from methods

      distributor: Reduce log level for no-op consolidations
    
    Change-Id: Iaa6d4a59d5cb26879500f2d36852eaa30efc5d7b
    Release-Notes: skip
    
  - PushOne: Remove unused addRef() method
    
    This is only used by tests and should have been removed when
    addRefBatch() superseded it.
    
    Change-Id: If9de1df29fd56a595fa4d4b2b4f5716264a67e11
    Release-Notes: skip
    
  - TasksStorage: Remove synchronized from methods
    
    These aren't expected to be necessary for correctness.
    
    Change-Id: Id23d3b385e289ba453638b76d6523016a5aabf2a
    
  - Place the replaying flag clearing in a finally
    
    This ensure that 'replaying' will be set to false even if an exception
    occurs in pruneNoLongerPending(), otherwise if would be possible for the
    distributor to get "stuck" and never be able to run again.
    
    Release-Notes: Avoid opportunity to inadvertently block the distributor
    Change-Id: I4628a574ad54ca6abd591138edc48e12a39447e7
    
  - Demote delete errors when distributor is enabled
    
    Since delete errors for Tasks is expected after recovery (when another
    nodes starts up) when running with a multi-primary setup, demote them to
    "atFine()" level when the distributor is enabled. This avoids errors in
    the logs during normal multi-primary operation.
    
    Release-Notes: Reduced log level for Task deletion errors in MP setups
    Change-Id: Iccca2e1bd2b91b91e12a14c4e473c8a6df6fd4b7
    
  - distributor: Reduce log level for no-op consolidations
    
    It's expected that the replication distributor will generate many of
    these log messages on a busy instance because it will repeatedly
    re-schedule the same ref updates. Since those messages likely aren't
    operationally interesting, reduce the log level to atFine when
    scheduling is happening based on stored replication tasks and the ref is
    already scheduled in the push task.

    Release-Notes: Reduced log level for no-op distributor push consolidations
