      vfs: add IO read/write methods that accept ByteBuffer · 1de61da6
      Tigran Mkrtchyan authored
      Motivation:
      The use of ByteBuffer for IO operations adds more flexibility as ByteBuffers
      can be sliced, shared and passed directly to various channels. Moreover, any
      byte array can be easily wrapped into ByteBuffer, if needed.
      
      Modification:
      added vfs#read and vfs#write methods with default implementation falling
      back to byte array based methods to maintain backward compatibility. Updated
      OperationREAD and OperationWRITE to use the new methods. Deprecate byte
      array based methods.
      
      Result:
      more flexibility with same functionality.

      nfs4: use ConcurrentHashMap for open file tracking · c798bc1a
      Tigran Mkrtchyan authored
      Motivation:
      in a highly concurrent environment the ConcurrentHashMap hash map has
      a better throughput than synchronized hashmap.
      
      Benchmark                                                (map)   Mode  Cnt       Score       Error  Units
      FileTrackerBenchmark.fileTrackerHashMapTest      HashMap  thrpt   25  691051.876 ± 23720.699  ops/s
      FileTrackerBenchmark.fileTrackerHashMapTest  ConcHashMap  thrpt   25  792051.898 ± 18111.740  ops/s
      
      Benchmark with 48 concurrent clients.
      
      Modification:
      Update FileTracker to use ConcurrentHashMap to track open files
      
      Result:
      better throughput in concurrent environment

      nfs4: simplify stateid4 class · 59550a9c
      Tigran Mkrtchyan authored
      Motivation:
      stateid4 is a struct that holds a byte array and int. No need
      for extra wrapper around int.
      
      Modification:
      use plain int to reduce object creation.
      
      Result:
      simpler code.

      nfs: make spring dependency scope `provided` · 3b8d58d2
      Tigran Mkrtchyan authored
      Motivation:
      as nfs-spring module expected to be used in spring based application,
      we can expect spring libraries to be available at the runtime.
      
      Modification:A
      make spring dependency scope `provided`
      
      Result:
      less mess with transient dependencies for spring based apps.

      Tigran Mkrtchyan authored
      Motivation:

      nfs4: getattr should return lease time configured on state handler · 1cf016b0
      Tigran Mkrtchyan authored
      Motivation:
      if server uses another non default value for leas time, then value
      returned by GETATTR is incorrect.
      
      Modification:
      introduce NFSv4StateHandler#getLeaseTime and use it to get the value of
      FATTR4_LEASE_TIME attribute.
      
      Result:
      a server with non default lease time will return the correct value on
      getattr.

      nfs4: update NFSv4StateHandler to store lease time as seconds · 248c8779
      Tigran Mkrtchyan authored
      Motivation:
      according to rfc7530, nfs_lease4 is 32 bit integer and expressed in
      seconds. This doesn't match with current internals of NFSv4StateHandler.
      
      Modification:
      update NFSv4StateHandler to store lease time as seconds.
      
      Result:
      no visible changes. Ground work for up-coming changes.

      nfs4: make extended NFSv4StateHandler constructor public · 06151918
      Tigran Mkrtchyan authored
      Motivation:
      the NFSv4StateHandler(leaseTime, instanceId, clientStore)  constructor
      can be used by NFS servers to control NFSv4StateHandler instance
      creation. As extended constructor is package protected, thus control is
      unavailable to other modules.
      
      Modification:
      make extended NFSv4StateHandler constructor public. Updated javadoc.
      
      Result:
      more control on how instance of NFSv4StateHandler created.
