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
- Mayor Feature Improvement, add MASTER - SLAVE - GRID
Now able to Create, Manage and Control a MESH of
Processes or Threads.
- Mayor Feature Improvement, add WORKER jobs
Distribute work on multiple jobs of the same kind
- Mayor Bug-Fix, improve process shutdown and cleanup
v 3.3 12 June 2009
- Add new programming language "C#"
- Add new method "Init" to initialize the spawn startup executable
-> now JAVA got the long missing "--spawn" support
- Add new method "ErrorC" to create a libmsgque conform error
- Improve Event-Loop to cleanup items on Io error
- Update the performance figures including new C# results
- Add native windows build using "Visual C# 2008 Express Edition"
v 3.2 21 May 2009
