v0.12.0 (kinetic-protocol 3.0.5)

  • KineticSession is now supplied as an opaque instance pointer from KineticClient_CreateSession
    • Passed KineticClientConfig is now deep copied and can be discarded after session creation.
  • Updated KineticClient_Put to allow storing an object with an empty value with a NULL data pointer supplied.
  • Added new KineticAdminClient API (see include/kinetic_admin_client.h)
    • Reloacted existing admin methods to admin API
      • KineticClient_InstantSecureErase => KineticAdminClient_InstantErase/KineticAdminClient_SecureErase
      • KineticClient_GetLog => KineticAdminClient_GetLog/KineticAdminClient_GetDeviceSpecificLog
      • KineticClient_FreeDeviceInfo => KineticAdminClient_LogInfo
  • Updated kinetic-c-util to support new Admin API. Still need to add support for printing info returned from KineticAdminClient_GetLog
  • Changed kinetic-c-util API to use getopt_long for operations in addition to parameters and added usage info via --help/-? option.
  • Fixed potential memory leak when logging protocol buffers.
  • Fixed potential imbalance in concurrent operations semaphore.
  • Status code changes
    • Changed
      • KINETIC_STATUS_HMAC_EMPTY => KINETIC_STATUS_HMAC_REQUIRED
    • Added
      • KINETIC_STATUS_MISSING_PIN
      • KINETIC_STATUS_SSL_REQUIRED
      • KINETIC_STATUS_DEVICE_LOCKED
      • KINETIC_STATUS_ACL_ERROR
      • KINETIC_STATUS_NOT_AUTHORIZED
      • KINETIC_STATUS_INVALID_FILE
      • KINTEIC_STATUS_DEVICE_NAME_REQUIRED
      • KINETIC_STATUS_INVALID_LOG_TYPE
      • KINTEIC_STATUS_HMAC_FAILURE
      • KINETIC_STATUS_SESSION_TERMINATED
  • Set larger timeouts for operations that tend to take approx. 10 seconds, to prevent non-deterministic failures.
  • API change: Eliminated KineticClientConfig.writerThreads, since sender threads are gone.
  • Changed to use stock protobuf-c 1.1.0 which also necessitated upgade to protobuf-2.6.0.
  • Added auto-generated version info which is prepended to log and can be queried via KineticClient_Version()
  • Added support to gracefully handle remote hangup.
    • The session will be shutdown.
    • All pending/new operations will return KINETIC_STATUS_SESSION_TERMINATED and termination reason can be queried on the given session via KineticClient_GetTerminationStatus(session).

v0.11.2 (kinetic-protocol 3.0.5)

  • Changed all threads to block indefinitely and be fully event-driven.
  • Added logging of all assertions to provide debugging info in the absence of debug symbols.
  • Fixed race condition in message bus listener which could lead to data corruption.
  • Fixed race condition that could cause more than the max number of thread pool threads to be created.
  • Fixed potential buffer overrun in logger.
  • Fixed bug with mishandling of unsolicited status responses from the drive prior to drive terminating connection.
  • Removed ruby/rake as non-development build prerequisites.
  • Added make json, json_install and json_uninstall tasks for json-c.

v0.11.1 (kinetic-protocol 3.0.5)

  • Fixed race condition causing timeouts to not be handled resulting in a deadlock.
  • Fixed extremely high CPU usage during loaded and idle times.

v0.11.0 (kinetic-protocol 3.0.5)

  • Changed API to use a KineticClientConfig struct, to keep future configuration changes from breaking the source API.
    • NOTE: KineticClientConfig and KineticSessionConfig rely on C99 struct init.
      • Unconfigured fields will be reverted to defaults if set to 0.
      • These structures must be configured via C99 struct init or memset to 0 prior to population for backwards compatibility.
  • Added options for the number of writer, reader, and max threadpool threads, with defaults.
  • Added KineticClient_FreeDeviceInfo to free the KineticDeviceInfo structure allocated by KineticClient_GetLog.
  • Added several new examples under src/examples/.
  • Added json-c library dependency which will be used for JSON-formatted ACL files for upcoming Admin API and multi-cast drive discovery tool.

v0.10.1 (kinetic-protocol 3.0.5)

  • Fixed regression in 0.10.0 where a GET with metadataOnly=true would result in a crash if a value field was not provided
  • Added system tests for P2P operations which are now fully validated and working on HW
  • Fixed misue of pthread_join status in thread pool which was causing shutdown issues in GCC builds

v0.10.0 (kinetic-protocol 3.0.5)

  • Added put_nonblocking and get_nonblocking examples
  • Added KineticSemaphore API to provide a simpler wrapper around a common use of pthread condition variables as a thread safe way to signal when an async operation has finished
  • Switched internal message infrastructure to use a threadpool. This will allow for a much higher number active connections and outstanding commands.
  • KineticClient_Init now returns a KineticClient pointer (internally, it's a handle to the threadpool) that must be passed to KineticClient_CreateConnection() in order to create new connections and must also be passed to KineticClient_Shutdown() on shutdown
  • Improved I/O examples to demonstrate client write operations for blocking/non-blocking (asynchrounous) and single/multi-threaded.
  • Added consolidated performance test which reports metrics on PUT/GET/DELETE sequences (test/system/test_system_async_throughput.c).

v0.9.2 (kinetic-protocol 3.0.5)

  • Added missing mutex lock causing a concurrency issue.
  • Added profiling to test/system/test_system_async_io.c

v0.9.1 (kinetic-protocol 3.0.5)

  • Added get_key_range.c example for KineticClient_GetKeyRange().

v0.9.0 (kinetic-protocol 3.0.5)

  • Changed API to use a KineticSession with a pointer to private session/connection info in place of the old KineticSessionHandle.
  • Added FLUSHALLDATA operation via KineticClient_Flush()
  • Added GETPREVIOUS/GETNEXT operations via KineticClient_GetPrevious()/KineticClient_GetNext()
  • Replaced KinticClient_Connect()/Disconnect() with KineticClient_CreateConnection()/DestroyConnection(), since the connection structure is dynamically allocated and populated in the provided KineticSession. KineticClient_DestroyConnection() MUST be called on the an established KineticSession in order to shutdown the connection and free up resources.
  • Added initial implementation of PEER2PEERPUSH which does NOT yet support chaining via KineticClient_P2POperation().
  • Fixed bug with mutex locking causing an assert failure and subsequent crash.
  • Fixed leaking of destroyed connections and they are now properly freed upon call to KineticClient_DestoryConnection().
  • Fixed bug where some unrecoverable socket errors could cause retries when unintended.
  • Modified PDU flow control in order not stall transmission on request PDUs when Value payload is empty or of small size.

v0.8.1 (kinetic-protocol 3.0.5)

  • Added GETLOG operation.
  • Added thread-safety to allow multiple client threads within the same session.
  • Added I/O examples to demonstrate client write operations for blocking/non-blocking (asynchrounous) and single/multi-threaded.

v0.8.0 (kinetic-protocol 3.0.5)

  • Updated to use Kinetic Protocol v3.0 (3.0.5)
    • NOT backwards compatible with earlier versions of Kinetic Protocol
    • Kinetic device firmware must be updated to a release supporting v3.0 protocol!
  • Added asynchronous/non-blocking execution option to all operations (GET/PUT/DELETE/GETKEYRANGE).
    • A given operation is carried out in asynchronous mode if a closure callback with optional data is supplied.
  • ByteArray and ByteBuffer types are now supplied directly in the byte_array.h public interface file.
  • Fixed a concurrency issue that intermittently produces a crash in kinetic_allocator in a threaded context

v0.7.0 (kinetic-protocol 2.0.6)

  • Added blocking GETKEYRANGE operation.

v0.6.0 (kinetic-protocol 2.0.6)

  • Added blocking GET and DELETE operations.
  • Added Makefile build implementing standard (make; sudo make install) interface.
  • Added creation/installation of static (.a) and dynamic (.so) libraries
  • Added ByteArray type for buffer management.
  • Added Kinetic_KeyValue type for key/value pair handling.

v0.5.0 (kinetic-protocol 2.0.4)

  • Added blocking PUT operation
