-
-- (2007-01-12) Make enabling/disabling the direct write optimization
-  runtime rather than compile time.
-
-
-Bugfixes
---------
-
-- (2007-01-09) Don't open new channels unless the channel id was
-  invented by our peer. Also, don't send a reply when an rpc request
-  error occurs. (avoid infinite error response loop)
-
-- (2006-09-21) Handle BAD_REQUEST/NULL method name case. When a bad
-  request was handled, the method name (NULL) would cause the method
-  lookup to crash. This should be resolved now.
-
-- On connection close: discard packets from the inner packet queue
-  even if the outer packet queue is empty. Not doing this could
-  trigger a resource leak if a dummy packet responsible for cleanup
-  (and channel closing) was left in the inner queue after the
-  connection was closed.

-New Dependencies
-----------------
-
-- vespalib (for test framework)
-
-
-Removed Code/Features
----------------------
-
-- Moved the core test framework into vespalib. FNET now depends on
-  vespalib for this. The FNET test framework is now implemented on top
-  of the test framework supplied by vespalib. Also, the vespalib test
-  script (testrun.sh) is used to control the running of FNET tests.
-
-- Removed FNET_LogHandler class. This removes the simple logging
-  framework located in FNET. It was deprecated several versions ago,
-  and all internal logging in FNET is now done using the new log
-  module.
-
-- Removed OO RPC Support (RPC with support for objects and
-  classes). This is done to simplify the overall design of RPC, which
-  also makes it simpler to implement compatible components in other
-  languages. RPC packet codes and error codes have been re-enumerated
-  to cover up the holes left by the removed support for OO RPC. The
-  protocol documentation has been modified to reflect the new RPC
-  design. NB: this makes RPC incompatible with older versions of FNET.
-
-
-Spiral
-------
-
-Spiral is a simplified single-threaded RPC abstraction layer. It is
-intended for truly single-threaded applications that does not want to
-mess around with the complete FNET API. Spiral currently only supports 
-the RPC client aspect.
-
-
-New Features
-------------
-
-- Added support for limiting the size of input/output buffers for
-  connections. This is done by invoking the
-  FNET_Transport::SetMaxInputBufferSize and
-  FNET_Transport::SetMaxOutputBufferSize methods.
-
-- Added FNET_Connection::GetQueueLen method that may be used to obtain the
-  number of packets currently located in the packet output queue.
-
-- Added support for enable/disable read and disable write events for
-  io components. This is used by the support to select on external
-  file descriptors.
-
-- Added support to shrink databuffers. This is used by the support to
-  limit input/output buffers.
-
-- Added support for selecting on external file descriptors by using
-  the FNET IO component framework. This includes using the
-  FNET_FDSelector class and the FNET_IFDSelectorHandler interface.
-
-- Better support for single-threaded compile. The test system has
-  been modified to work when compiled single-threaded. A new test
-  macro named TEST_THREADS may be used by tests that need threads to
-  run. This will result in the test begin skipped if threads are not
-  supported.
-
-- Added FRT_ISharedBlob interface with corresponding support. This may
-  be used to share the same memory regions between multiple
-  requests. Also, all shared blobs will be subref'ed by the request
-  as soon as the request packet is encoded to the connection output
-  buffer.
-
-
-Bugfixes
---------
-
-- Fixed a minor bug in the xsync daemon; close other end of pipe after
-  fork, to avoid hang in mother process if child fails.

-Public testing toolkit
-----------------------
-
-The FNET testing toolkit has been made public and is now a part of the
-fnet library. The macros have been renamed to all start with
-'TEST_'. The local fnet tests have been modified and an example test
-program has been added.
-
-
-New logging API
----------------
-
-All logging has been converted to use the new "log" module
-and its API.  All functions in class FNET_LogHandler are now
-deprecated, in particular FNET_LogHandler::SetLogMask and
-FNET_LogHandler::SetLogHandler no longer have any effect.
-All users of fnet will need to link with the "log" library.
-
-
-Misc

-FRT/RPC Lobotomy/Cleanup
-------------------------
-
-The support for local invocation (and location transparency) is
-removed. The code is also somewhat simplified to reflect the now less
-general nature of things. It hurts to see so much thought go down the
-drain, but it greatly reduces maintenance complexity and simplifies
-future development. Who needs sub microsecond invocations anyway...
-
-Changed code to avoid warning messages produced by gcc 3.3 and later 
-when compiling with the -Weffc++ option.
-
-
-Removed Code
-------------
-
-- FNET_ITransportHook
-- FNET_IPingable
-- FNET_Pinger
-- FNET_ServerInfo
-- FNET_Transport::SetMinEventTimeOut
-- FNET_Transport::SetPingInterval
-- FNET_Transport::AddPingTarget
-- FNET_Transport::RemovePingTarget
-- FNET_Transport::HookNow
-
-
-New Features
-------------
-
-- Added preliminary support for 2-way RPC.
-
-- Added support for invoking RPC methods without having an FRT_Target.
-
-- Added a Reset() method to the reflection manager that removes all
-  methods.
-
-- Added a method mismatch rpc hook that may be used to catch method
-  calls not matching any methods.
-
-- Added support for rpc session state (All rpc calls made on a single
-  connection is referred to as a session). This was done by adding a
-  context to each connection (used to store the session state), making
-  it possible to obtain the underlying connection given
-  the rpc request object and adding special rpc hooks that are called
-  when a connection is established, when a connection is lost and
-  right before a connection is deleted.
-
-- The transport object now comes with a built-in scheduler object.
-
-- The FNET_Scheduler constructor may be given the current time. This
-  simplifies running the scheduler in a simulated environment.
-
-- A Sync method has been added to the connection class. This method
-  may be used to block until all previously posted packets have been
-  encoded.
-
-- Added InTub method to the memorytub class. This method may be used
-  to check if the tub owns a given byte of memory. This feature is
-  primarily used for regression testing.
-
-- The FNET_Connector class has been given a GetPortNumber method to be
-  able to extract the port number of the underlying server socket.
-
-- Allow listening on port number 0.
-
-- Add FRT_Target::GetConnection() method. Only returns a pointer to
-  the connection owned by the target. No new references are allocated.
-
-
-API changes
------------
-
-- The FRT supervisor may be constructed either in stand-alone mode, or
-  based on an external transport object and an external thread
-  pool. The transport proxy methods may only be used when in
-  stand-alone mode.
-
-- The scheduler no longer implements the transport hook interface
-  (removed). The virtual Tick method has been replaced by the
-  non-virtual CheckTasks method.
-
-- The transport Main/Start methods no longer take a transport hook as
-  parameter (the interface has been removed). Similar functionality
-  may now be obtained by using the transport InitEventLoop and
-  EventLoopIteration methods.
-
-- The RPC target InvokeAsync method now returns bool, true means that
-  the method completed immediately. false means the invocation is in
-  progress.
-
-- The FRT_IRequestWait::RequestDone method now takes a second
-  parameter; a bool indicating whether this invocation is done
-  synchronously (directly from the invoke method).
-
-
-Internal changes
-----------------
-
-- Added IOC CleanupHook method that is called right before an IOC is
-  deleted. This is used by the FNET_Connection class to support a
-  connection cleanup callback which in turn is used by the FRT_Supervisor to
-  activate the SessionFini hook needed for RPC session support.
-
-- Statistics updating is now done with a scheduled stats update
-  task. This reduces the complexity of the event loop.
-
-- The connection write method now avoids writing 0 bytes to the
-  network. Also, empty writes are silently ignored since using the
-  packet queue for control packets is perfectly legal.
-
-- Channel IDs are now chosen in a way that is future compatible with
-  2-way channel creation.
-
-
-Misc
-----
-
-- Store listen/connect spec in IOC and use it in IOC related log
-  messages.
-
-- Added rpc proxy example program that may be useful for debugging.
-
-- Added FNET_DummyPacket helper packet class that may be used to
-  implement hooks in the connection output packet queue.
-
-- The FNET_Packet::NoPCODE() and FNET_Connection::NoID() methods have
-  been replaced by the FNET_NOID macro.
-
-- Added FNET_ prefix to DISABLE_DIRECT_WRITE compile flag.
-
-- Added FNET_SANITY_CHECKS compile flag. This enables some extra
-  sanity checks in the event loop.
-
-- Added generic cross-host testing support as part of testing
-  framework (xtest make target removed). This includes the xsync
-  daemon used to sync test states between hosts. The environment
-  variables PORTBASE and PEER are used to control testing behavior.
-
-- In regression test framework: enable output from passed test cases
-  to be collapsed to reduce logging.
-
-- Added support for mutex instrumentation. This requires a version of
-  FastOS supporting instrumented mutexes.
-
-- Added FRT_Supervisor::GetListenPort() method.
-
-
-Bugfixes
---------
-
-- RPC: Handle request return (after request detach) while still
-  inside sync invocation method correctly (also added to regress
-  test).
-
-- RPC: ensure that the cleanup handler is run also when the request is
-  recycled by the user without making the trip back to the request
-  pool.

-Bugfixes
---------
-
-- Avoid overlap between chunk header and chunk data in FRT memorytub.
-
-- Remove race around single req wait where condition could be
-  destructed while being locked.
-
-- Don't set connection state to closed if connect fails
-  synchronously. This caused a channel lost event to be sent on the
-  admin channel that caused a deadlock in the serverinfo class. It is
-  also an API improvement, since connect now fails either
-  synchronously or asynchronously (not both).

-New Features
-------------
-
-- Added support to construct an FNET_DataBuffer based on a
-  preallocated buffer.
-
-- Added support for scheduling a task to be run as soon as possible.
-
-- Added support for killing a task so that it may not be scheduled in
-  the future.
-
-- Added databuffer methods to write data without checking for free
-  space. These methods have a 'Fast' suffix.
-
-- Added AssertValid method that may be called anytime to assert that
-  the databuffer is in a legal state.
-
-- Added endian detection. Use the FNET_Info::GetEndian method to
-  obtain host endian.
-
-- Added methods to read/peek information stored in reverse internet
-  order (little endian) in a databuffer.
-
-- VPATH compilation.
-
-
-Internal Changes
-----------------
-
-- Removed asserts used to check for valid data in databuffer read
-  methods.
-
-- When posting a packet, try to write it to the network directly (if
-  there is no other pending write operations). Post
-  an enable write event to the transport thread if there is pending
-  work after a direct write has been attempted. This behavior may be
-  disabled by using the --disable-direct-write configure option.
-
-
-Misc
-----
-
-- Added static instance of FNET_CMD_NOCOMMAND control packet for
-  completeness.
-
-- Moved fastserver stuff to the fastserver4 cvs module.
-
-- Simple regress test framework. Run tests with 'make test' from
-  fnet/src. Use 'make xtest' to run cross-host testing. This requires
-  setting the PORT and PEER environment variables to sane
-  value. Example: to run a cross-host test between host A and host B
-  using port 8000 (on both hosts); run 'make PORT=8000 PEER=B xtest'
-  on host A and 'make PORT=8000 PEER=A xtest' on host B.
-
-
-Bugfixes

-
-FRT ([F]NET [R]emote [T]ools) [middle-ware library]
----------------------------------------------------
-
-The FRT library is a layer on top of FNET supporting a proprietary RPC
-protocol. In addition to the network protocol, the FRT library also
-contains API support for location transparent dynamic method
-invocation (examples and regress tests also included).
-

-- Handle EOL returned from socket read. This lets FNET handle peers
-  that close connections nicely. Previously this would result in a
-  very tight event loop reading EOL from the socket in each iteration.
-
-- Avoid time measurement errors in scheduler by using absolute values
-  for bucket timeouts rather than accumulated delta values. If the
-  scheduler was invoked very often, it would appear that time stood
-  still.

-Compiler nitpicks
------------------
-
-- Renamed TICK to SLOT_TICK in scheduler class to avoid conflict with
-  macro on Solaris.
-- Removed comma at end of enums in fs4 example packet library.
-- Use public inheritance in fsearch_maxthreads fs4 example
-  application.
-- Conceal infinite loop in fsearch_somethreads fs4 example
-  application.
-- Cast error-code to signed value before applying negation in
-  fs4 searchtest example application.
-- Cast enum to uint32_t to avoid constructor confusion in proxy
-  example application.
-- Explicitly cast stat values to float.
-
-
-Misc

-
-- Removed memory leak in scheduling test to avoid HUGE memory leak
-  report on application exit.
-

-=======================================================================
-                         FNET V_1_1_0_RELEASE
-.......................................................................
-
-
-API Changes
------------
-
-Added method bool FNET_IServerAdapter::InitAdminChannel(FNET_Channel
-*) That must be implemented by server applications using FNET. The
-method is called when a new incoming connection has been established
-in order to let the application keep track of its current
-clients. This channel works just like normal channels. The only
-difference is that it is opened before any packets are received,
-thereby allowing the application to implement connection-oriented
-stuff like proxies. Implementing this method to always return false
-will preserve old behavior. NOTE: closing the connection directly (by
-invoking Close()) is allowed from the InitAdminChannel method (This is
-an exception from the general rule that the application should close
-all connections with async events. The reason for this exception is to
-allow better resource management).
-
-Added an FNET_Context parameter to the FNET_Connection constructor and
-to the FNET_Transport::Connect method. This was done to enable the
-application to set the admin channel context in the client end-point
-of a connection. Also, VOIDP=NULL is used as default context, instead
-of the previously used INT=0xffffffff (FNET_Connection::NoID()).
-
-Added a parameter of type FNET_ITransportHook to the
-FNET_Transport::Start method in order to enable sharing the transport
-thread without the need to create a wrapper object (The parameter is
-optional with NULL as default value).
-
-Made the FNET_ITransportHook parameter to the FNET_Transport::Main
-method optional (default value is NULL).
-
-Server info objects may now be marked as 'bad'
-[MarkBad()/ClearBad()/IsBad()]. If a server (info) is marked as bad,
-FNET will try to keep it down, rather than up. Note that node badness
-may be set by the application code in any thread and is not protected
-by any locks. The most sensible use of this flag would be to use it as
-an async signal, raising it if a server goes bad, and never lowering
-it again (ClearBad() is implemented for completeness, but needs to be
-used with care).
-
-Added new method FNET_Channel::CloseAndFree() that may be used to
-close and free a channel in a single operation. This is equivalent
-with first invoking Close(), then Free(), but is more efficient.
-
-The packet streamer interface has been modified in order to support
-context-dependent un-streaming of packets and variable length packet
-headers. This has resulted in the following method changes:
-
------
-bool
-FNET_IServerAdapter::InitChannel(FNET_Channel *channel,
-                                 FNET_Packet *packet)
------
-||
-\/
------
-bool
-FNET_IServerAdapter::InitChannel(FNET_Channel *channel,
-                                 uint32_t pcode)
------
-
-This reflects the fact that in order to do context-dependent packet
-un-streaming, we need to resolve the context of the channel that
-should receive the packet before un-streaming the packet. This also
-means that the packet itself is not available when opening server-side
-channels.
-
------
-FNET_Packet *
-FNET_IPacketFactory::CreatePacket(uint32_t pcode)
------
-||
-\/
------
-FNET_Packet *
-FNET_IPacketFactory::CreatePacket(uint32_t pcode, FNET_Context context)
------
-
-The context is propagated to the packet factory in order to eliminate
-the need to change the FNET_Packet::Decode(...) method.
-
------
-uint32_t
-FNET_IPacketStreamer::GetHeaderLen()
-
-uint32_t
-FNET_IPacketStreamer::GetPacketLen(FNET_DataBuffer *src)
------
-||
-\/
------
-bool
-FNET_IPacketStreamer::GetPacketInfo(FNET_DataBuffer *src,
-                                    uint32_t *plen,
-                                    uint32_t *pcode,
-                                    uint32_t *chid,
-                                    bool *broken)
------
-
-The packet info is extracted before the packet is un-streamed in order
-to locate the channel that should receive the packet. This change
-gives us support for variable length packet headers and a way to
-signal that the connection is broken.
-
------
-FNET_Packet *
-FNET_IPacketStreamer::Decode(FNET_DataBuffer *src, uint32_t *chid)
------
-||
-\/
------
-FNET_Packet *
-FNET_IPacketStreamer::Decode(FNET_DataBuffer *src, uint32_t plen,
-                             uint32_t pcode, FNET_Context context)
------
-
-The packet info is injected as parameters to avoid having to extract
-it from the packet a second time. Note that the chid has been replaced
-by the context of the channel that will receive the packet. This
-completes the support for context-dependent packet un-streaming.
-
-
-Internal Changes
-----------------
-
-Allow IOC_DELETE event before IOC_ADD event. This enables the
-application to post an event indicating that the connection itself
-should be closed when invoked to open the admin channel on that
-connection (only applies to server connections).
-
-Optimized FNET_DataBuffer by using pointers to define dead/data/free
-sections of the buffer.
-
-Each connection now has its own FNET_ChannelPool object instead of
-sharing an FNET_ObjectPool. This reduces locking.
-
-The methods on FNET_Channel has been un-inlined in order to
-instantiate FNET_Connection objects with an inlined FNET_ChannelPool
-object which in turn has inline FNET_Channel objects.
-
-Make sure that the packets posted on a connection are freed in the
-same order as they were posted, even if the connection goes down. This
-is done to enable the application to use packet free order for syncing
-purposes. It also enables the usage of packets that perform code in
-the free method that requires that all previously posted packets have
-already been freed (Like memory pool cleanup code).
-
-Changed some log messages to FNET_LOG_DEBUG.
-
-
-New Control Packets
--------------------
-
-- FNET_CMD_TIMEOUT : This control packet command may be used to signal
-                     a timeout. Note that FNET does not use timeout
-                     packets internally. They are only included to
-                     ease the implementation of timeout signaling in
-                     applications using FNET.
-
-- FNET_CMD_BAD_PACKET : This control packet signals the reception of
-                        a packet that could not be un-streamed. It
-                        will be delivered in place of the packet that
-                        was invalid.
-
-
-New Classes
------------
-
-- FNET_Task (schedulable tasks; timeouts etc.)
-- FNET_Scheduler (class for scheduling tasks)
-- FNET_ChannelPool (per-connection channel pooling)
-
-
-Removed Classes
----------------
-
-- FNET_ObjectPool
-
-
-New Examples
-------------
-
-- proxy : A simple proxy implementation showing how FNET may be used
-          to handle raw data as packets and also how to focus on
-          connections rather than channels.
-
-- timeout : Simple application showing how to use the
-            task/scheduler classes to implement timeout support.
-
-
-Bugfixes
