    • 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 (set to 0/NULL).
    • 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 thread pool 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

v0.8.2 (kinetic-protocol 3.0.5)

• Merged in all fixes and feature additions from 0.8.1 to 0.9.0 prior to public API breaking changes

v0.9.1 (kinetic-protocol 3.0.5)

• Added keys->used to ByteBufferArray to reflect the number of buffers actually used, and updated KineticClient_GetKeyRange() to populate it.
• 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.
