20 Jan 2010: v NHI1-0.12, PLMK-2.1 and libmsgque-5.1

This release embed "sqlite" support into the PLMK kernel.
As first step only the memory management is used.


14 Jan 2010: v NHI1-0.11, PLMK-2.0 and libmsgque-5.0

This release add support for the "Factory" design pattern.

The "Factory" is an important part of the object management and has the
following basic features:
 * create a new instance identified by an "Identifier" or using an already
   available instance as template
 * cleanup and delete an instance
 * provide an "Identifier" for factory lookup and as an unique application name
 * identify the server in the network
.
The link between the "Factory-Identifier" and the "Factory-Interface" is
important for the future development of "libmsgque". Message-Routing,
Service-Location and Persistent-Transactions depend on this feature.

The relationship between the "MqFactoryS" and the "MqS" is the same as the
relationship between a "type" and an "instance" of the "type" in a regular 
programming language.
The "MqFactoryS" define the "type" of the server and the "MqS" define a single
instance of the server. Every kind of server has !!only one!! specific 
"MqFactoryS" object but every instance of a server has one "MqS" object used 
for object management. Decreasing the size and the complexity of a "MqS" object 
will improve the server performance.
In future more fields, defined in the "MqSetupS" attribute of the the "MqS" 
object, will move into "MqFactoryS" object.



29 Nov 2010: v NHI1-0.10, PLMK-1.8 and libmsgque-4.8

This release add support for the new programming-language "Go" from Google.


08 Nov 2010: v NHI1-0.9, PLMK-1.7 and libmsgque-4.7

This version adds the ability to:

* PHP language support.
* a new interface of the "ProcessEvent" function and the "startAs" configuration option.
* terminate an application from a callback with the "ErrorSetEXIT" function.

The PHP language is characterized by an extensive but undocumented C API. The number of 
features combined with a growing and moving language made the extension programming difficult
and lengthy. The successful PHP extension shows the flexibility and adaptability of NHI1.



22 Oct 2010: v NHI1-0.8, PLMK-1.6 and libmsgque-4.6

This release adds the ability to:

* Ruby language support (LNG)
* L)anguage A)bstraction L)ayer (LaL)
* G)arbage C)ollection (GC) Object-Mark

Ruby is an object-oriented programming language like Python. 
The new 'libmsgque' function (MqMark) was added to the GC support and marks all objects 
that are referenced within 'libmsgque'. The programmer now has the opportunity to replace 
internal functions such as: SysCalloc, SysMalloc, SysRealloc, SysFree, SysSelect, SysFork, 
SysServerSpawn, SysServerThread, SysServerFork, SysWait, SysUSleep, SysSleep, SysDaemonize, 
SYSEXIT, SysAbort to adapt to the environment (Lal).



08 Mar 2010: v NHI1-0.7, PLMK-1.6 and libmsgque-4.5

This is a 'major-feature-release' to add 'longtime-transaction' support.

A 'longtime-transaction' is a transaction with an infinite time period between the start
and the end. A 'longtime-transaction' is always a 'persistent-transaction'
too. The 'persistent' support is available as an in-memory solution on the 'application-server'
or in an additional 'bidirectional-filter' available for the next release.

A typical scenario for a 'longtime-transaction' is:

* A user with a client connect to the server and start a 'longtime-transaction' job.
  After a while the user shutdown the client and leave the office. At the next morning the
  user start the client again and the results are send from the server to the client.
* On a space mission the time-overhead between transaction start and end is large. It is
  usually not possible to keep the client-server-connection open all the time.
* On a military action-system the enemy try to interrupted the client-server-connection
  to disable data communication.

To use a 'longtime-transaction' the results are send to a 'client-service' registered with
MqerviceCreate. This service and addtional data (I call this data 'local-context-data')
have to be added to the 'longterm-transaction' package to be available in the result. On the
'link-target' the 'local-context-data' is initial stripped from the 'data-package' and is
later added to the results again.

The 'local-context-data' is added to the 'data-package' with MqSendT_START and MqSendT_END. 
The 'local-context-data' is read from the 'data-package' with MqReadT_START and MqReadT_END.


\subsection V0_7_sp service proxy support

A \e service-proxy (\RDocNsA{ServiceProxy}) is used to forward the entire \e data-package from one
context to an other context and is used in a \e filter like environment.

17 Feb 2010: v NHI1-0.6, PLMK-1.5 and libmsgque-4.4

This is a 'major-feature-release' to prepare the environment
for the new 'milestone-release' coming soon. 

 - theLink (libmsgque), PMLK
  + Performing memory cleanup using Garbage-Collection
      Find a safe moment to free unused memory
  + New message-logging API:
      MqLogC .... write string style message to stderr
      MkLogV .... write printf style message to stderr
      MkLogVL ... write vprintf style message to stderr


02 Feb 2010: v NHI1-0.5, PLMK-1.4 and libmsgque-4.3

This is a 'feature-release' to prepare the environment for the new 
'milestone-release' coming soon

 - theLink (libmsgque)
  + new feature - Recover from a Server or a Network downtime
      read more: html/theLink/changelog.htm
  + API addition:
      MqLinkGetTargetIdent ... identify the link-target
      MqLinkConnect .......... reconnect a broken client-server-link
      MqErrorIsEXIT .......... catch application-exit
  + update documentation and fix missing information
  + extend the test file: theLink/tests/trans.test


v NHI1-0.4, PLMK-1.3 and libmsgque-4.2

This is a 'maintenance' and 'reorganization' release to prepare the
environment for the new 'milestone' release coming soon

 - 15 Jan 2010
  + API reorganization:
      MqConfigGetFilter -> MqServiceGetFilter
      MqConfigGetIsTransaction -> MqServiceIsTransaction
      MqConfigGetToken -> MqServiceGetToken
      MqConfigGetParent -> MqLinkGetParent
      MqConfigGetCtxId -> MqLinkGetCtxId
      MqConfigGetIsConnected -> MqLinkIsConnected
      MqConfigGetMaster -> MqSlaveGetMaster
      MqConfigGetIsSlave -> MqSlaveIs
  + update documentation, reorganize the structure
      MAN: the API reference is now called with an "ref" postfix
        > man (lib|cc|cs|java|py|perl|vb|tcl)msgqueref
      LINK: the file 'theLink/libmqmsgque/msgque_mq.h' is now root source
        of documentation data and used to feed the MAN and the HTML docs
      HTML: centralize the 'context' documentation
  + add new 'public' API 'IEvent' or 'MqConfigSetEvent' to provide a function
    to be called on idle. Together with the new API functions
    'MqConfigSetIgnoreExit' and 'MkErrorSetCONTINUE' the server is now able
    to 'ignore' an application 'exit' and continue to work on events.
    The 'IEvent-API' get significant more power in future releases.
    Check out the example: 'example/LANG/Filter4.EXT'
 - 5 Jan 2010
  + change default value for 'wait' in ccmsgque function MqC::ProcessEvent
    from MQ_WAIT_ONCE to MQ_WAIT_FOREVER
 - 1 Jan 2010
  + switch the special token to delete 'all' token in MqServiceDelete from
    '_ALL' to '-ALL'. 
    -> Reason: the '_???' syntax is for internal use only.


v NHI1-0.3, PLMK-1.2 and libmsgque-4.1

Major - Feature - Improvement !!

- libmsgque/PLMK: add new technology "bi-directional filter"
  > the technology is used to extend an existing application without having
    the application source-code available.
  * http://nhi1.berlios.de/theLink/filter.htm
- NHI: add new tool "theGuard"
  > "theGuard" is used to protect the data traffic using data encryption
    and is based on the new bi-directional filter technology of libmsgque. 
  * http://openfacts2.berlios.de/wikien/index.php/BerliosProject:NHI1_-_TheGuard


v 0.2

This release is used for deeper integration of the Software "Tokyo Cabinet".
The software was forked and integrated into "theBrain" subdirectory "librain"
using "automake/libtool" technology. The project library dependencies were
changed to "automake convenience libraries". "theBrain" got new token's for
transaction support and database reorganization and was added into the
performance testing environment.


v 0.1

This is the first public release of "NHI1". The goal is to create the first 
"Non Human Intelligence" until 2040. The Project is the "master" project of 
several sub-projects like "theLink" (former known as libmsgque) or "theBrain" 
a persistent storage able to save a "theLink" data package without transfor-
mation. The next development cycle will be used to deep integrate "theLink" 
with "theBrain" to get the best link/brain combination available in business.


## OLD news from "libmsgque"

v 3.8

- BUG fix and CODE cleanup release
  complete the design of the configuration interface to "libmsgque"
  > now, all command-line configuration options are available as functions <
    Example: define an TCP server in the source with MqConfigSetIoTcp
  > configuration modifications are now possible at any time < 

v 3.7

- Add new programming language "VB.NET"
  Well "VB.NET" is using the CLR runtime and one goal was to prove if the
  promise of "Language Independent Programming" works -> YES
  Now supporting: C, C++, C#, Java, Python, Tcl, Perl, VB.NET
- Not surprising is the "VB.NET" has the same performance figures as "C#"
  and -> outperform <- Java, Python, Tcl, Perl
- PHP support was skipped because no "public" documentation is available 
  for the "Zend Engine 2.0" software (the base of PHP). This is interesting
  because "Zend" is a "commercial" company and it seems that the clause:
  "NO results are better than BAD results" is used.
- After adding of "VB.NET" was so easy I spend my time to improve the
  BUILD environment. Now language independent files like JAVA "class"
  and "jar" files or CLR "exe" and "dll" files were added to the distribution.
- Now I had to "convince" automake to use this files, even for a VPATH
  build. Automake does not do this by default but I was able to "teach"
  automake to do this.
- The rest of the time I used to add a new documentation block called
  "Tutorial" and is available for every supported programming languages.

v 3.6

- Add new programming language "Perl"
  The new language is added if the "--enable-perl" configure switch is used.
  Create and Install new perl module "Net::PerlMsgque".
  Use native perl "MakeMaker" build environment to create Perl-Conform build
  and perform a Perl_Conform installation.
- The dependency for Tcl is now optional
  The Tcl language is added if the "--enable-tcl" configure switch is used.
  Be aware that the test-environment depend on Tcl
- Add asynchronous background handler
  This handler is used to process errors not belonging to a transaction in
  a centralized manner. The feature was implemented as Interface (C++,Java
  ,C#) or as configuration option (C,Perl,Python,Tcl).
- Add signature based type checking
  Non-Typed languages without usable class or inheritance type checking now
  using this feature to create type-save code. This feature is used for Tcl
  and Perl.
- Add new Performance Test environment
  The new environment using a separated directory "performance" and does
  create better results combined with a clearly arranged result-table. Read
  more in "performance/README"


v 3.5

- Add new programming language "C++" :
  The new language is added if the "--enable-cxx" configure switch is used.
- C++ add a new design pattern to libmsgque based on the language requirements:
  1.  In "C++" a constructor can not call a "virtual" method. This is the main
      difference between "C++" and "C#" or "JAVA". This require that
      "Object" creation/deletion and "Link" creation/deletion have to be se-
      parated into two different tasks. The former (C# and JAVA) implementation 
      was to use a "feature-rich" constructor to setup a "Link" during object 
      creation. This was changed.
      A new methods "LinkCreate(..)" and "LinkCreateChild(..)" are introduced 
      for "Link" setup as counterpart for the "LinkDelete()" method. A new method
      "ConfigGetIsConnected()" return the "Link-Status" of the Object-Instance.
      With the new "Pattern" it is now possible to "reuse" a object-instance.
  2.  In "C++" a RTTI based Object-Creation is not possible. This task was
      shifted into a "Factory" pattern. A "virtual" method called:
                  "virtual MqC* Factory() const"
      is used to return a new object instance of the top-most class.
      The "Factory" pattern was used as "default" design pattern because of:
        - far more easy as the RTTI design pattern
        - available for every programming language
- change the default visibility for GCC functions to hidden "-fvisibility=hidden".
    -> This support the "Windows" binary design on Linux to create faster code.
- redesign of the main "struct MqS" and delete many of the data pointers
    -> create smarter and faster code
    -> only *one* pointer is used to used the entire API
- the "Filter" mode was redesigned and is using now the "Master/Slave" pattern
    -> code cleanup and standardization
    -> the IFilterFTR / IFilterEOF does now support a "pipelining" as "default"
- the "Error" handling was redesigned and moved into an independent "object"
  or "class". This was necessary to "transport" an "error" through the error
  stack of the "embedded" programming language.


v 3.4   28 June 2009
