The Factory add the ability to create NEW server-types on-the-fly and introduce the self-programming capability to NHI1. 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.

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). The connection of Ruby on libmsgque had light and shadow. The light was clearly a complete API that allows very fast classes and functions to be defined in C. The result was convincing in the performance test, and let Python, Perl and Tcl behind. The shadow was first of all the non-existent documentation. The initial enthusiasm for the thread link was to quickly and ultimately turned out to be unusable (no matter how many processors / cores are available in Ruby is only one thread is active and the others are blocked - ridiculous). Last I made the memory management (garbage collection) to create. I have no problem with Mark and sweep but without IncrRefCout and DecrRefCount is a torture and forced me to adapt my garbage collector. Finally, a note in their own right: will from now on, during the development of a work package, only source code and binaries for x86_64 - created Linux. The reason lies in the necessary acceleration of the development. The packages for other operating systems like Windows or BSD / MacOSX only be made at the end of a Work-Package.

ANNOUNCE: Major Feature Release - NHI1-0.7, PLMK-1.6 and libmsgque-4.5
Dear User, ANNOUNCE:Major Feature Release libmsgque: Application-Server-Toolkit for C, C++, JAVA, C#, TCL, PERL, PYTHON, VB.NET PLMK: Programming-Language-Microkernel NHI1: Non-Human-Intelligence #1 SUMMARY === This is a 'major-feature-release' to add 'longtime-transaction' support. A 'longtime-transaction' is a transaction with a possible 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 MqServiceCreate. 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.

ANNOUNCE libmsgque 3.5, ANNOUNCE (P)rogramming (L)anguage (M)icro(K)ernel 1.0
Dear Users; this is the ANNOUNCEMENT of: libmsgque 3.5 and the *first* public ANNOUNCEMENT of the: (P)rogramming (L)anguage (M)icro(K)ernel 1.0 libmsgque 3.5 = LibMsgque is an OS independent, programming language independent, and hardware independent solution to link applications together to act like a single application. In other words, LibMsgque is an application-server toolkit. changes from libmsgque 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 separated 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(..) were 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 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. (P)rogramming (L)anguage (M)icro(K)ernel 1.0 JAVA says: YOU can do whatever YOU want on every os YOU require but YOU have to use JAVA C# says: YOU can do whatever YOU want on every os YOU require but YOU have to have to use a CLR compatible language I say: YOU can do whatever YOU want on every os YOU require using the programming language YOU like most but YOU have to use the PLMK design pattern The PLMK is an afford to shift the design responsible away from the very heteros group of language designers to a free open and mature framework called PLMK. This framework is available for C, C++, C#, JAVA, PYTHON and TCL and was designed as C/C++ shared library. The library is able to plugin into the hosting programming language to take-over the responsibly for the application design. PLMK is *not* a programming language, the software programming is done using the hosting programming language *only*. - libmsgque is the first component of the PLMK framework - GET IT read more at: http://libmsgque.sourceforge.net/ get the software from:http://sourceforge.net/projects/libmsgque/ subversion archive: https://libmsgque.svn.sourceforge.net/svnroot/ /libmsgque/tags/libmsgque-3.5/ mfg aotto1968 -- http://mail.python.org/mailman/listinfo/python-list
Re: problem to write a THREAD enabled python extension
Stefan Behnel wrote: You forgot to create a thread state for the new thread. See the PyThreadState_New() function. this does not really solve the problem even if the original error does no happen anymore ... but a bucket of other error happen sometimes and this mean that time and (I call it so) internal state stuff has influence on the problem and create errors like: 1. http://mail.python.org/pipermail/python-list/2004-January/242740.html 2. various PyThreadState_Get - PyThreadState_Get: no current thread 3. sometimes ThreadState has NULL sometimes not and NULL create an CORE for tstate pointer access operations 4. ... a lot of other problems too all problems together I come to the conclusion: 1. I spend ~ 1week for a job done in C# or java in a day - and have no usable solution 2. python need a couple of 100+ C API function for the same job java need 10+ 3. the design on the C-API is amateurish - significant parts are implemented as GLOBAL variables 4. the thread support is not more than a joke - go to 3 5. after pay a lot of effort to get something working the final solution is significant slower than C# or JAVA 6. you can not truss any-thing in python because you never know if under some circumstance you get a CORE the resulting PYTHON code is usable but not significant more readable as JAVA, C* or even C++ code mfg aotto1968 -- http://mail.python.org/mailman/listinfo/python-list
problem to write a THREAD enabled python extension
Hi,
the following scenario:
1. using GIL
2. a pthread is created in a library and have to be announced to python
3. the thread is created in a PyObject_CallObject function call from
extension c code using a other extension c-code function called
from python code
python CRASH with invalid thread-state object
http://www.linuxjournal.com/article/3641
has information that GIL is NOT able to keep thread state information
for cross thread operation.
workaround -
..
PyGILState_STATE gilState = PyGILState_Ensure(); // PyEval_RestoreThread
// Call Python/C API...
PyGILState_Release(gilState); // PyEval_SaveThread
..
// Create new thread...
..
PyGILState_STATE gilState = PyGILState_Ensure(); // PyEval_RestoreThread
// Call Python/C API...
PyGILState_Release(gilState); // PyEval_SaveThread
..
the problem is that PyGILState_Release have to be done in the call of
PyObject_CallObject and not in the extension c-code
- for now i call it impossible to provide thread support if thread is
created in extension code
- more info by valgrind

ANNOUNCE a minor feature improvement of libmsgque ... What is LibMsgque = LibMsgque is an OS independent, Programming Language independent and Hardware independent solution to link applications together to act like a single application. Or with other words, LibMsgque is an Application-Server toolkit. Highlights of the current Release: = This release introduce a new windows build into the LibMsgque world. The build switched from the GNU toolchain to Visual C++ 2008 Express This is the official statement for this switch: The decision to use GNU tools on Windows including automake, autoconf, libtool and mingw was wrong. The tools were replaced by Visual C++ 2008 Express. The reason was the extremely low performance of the GNU tools on Windows which end up in a 20min overhead per configuration life-cycle and a 5min overhead per build. This end up in an additional TCO of 2000euro per release.

Re: PYTHONPATH on Windows XP module load problem
Hi, I try to use distutils and setup.py to create an C extension Now a list of problems: 1. I'm using automake, autoconf to setup the build-environment for example CPPFLAGS - how can I transport the CPPFLAGS on the commandline to setup.py I can not use the define_macros argument in the setup.py script 2. the following shared library is created: build/lib.linux-x86_64-3.0/pymsgque.so - in my tool a test environment is included this mean after a build but before install a test is done. this mean that the library have to be found and used by the test-environment. - the problem is that the directory name build/lib.linux-x86_64-3.0/ is system-depend - question: how I get an unique system independent name or just in general how I solve this kind of problem 3. why is no .pyd file created ? - pyd is the extension name supported mfg Andreas Otto -- http://mail.python.org/mailman/listinfo/python-list

who is calling the base class __new__ method
Hi,
I have the following example:
1. I create a new type in C with it's own tp_new called PyMqS_new
2. I use this type as basis-class for a python class called Server.
class Server(pymsgque.MqS):
- I checked: self.__class__.__bases__: (class 'pymsgque.PyMqS',)
from a Server startup code and the base is available
3. A object of Server should create a new object of class Server in
the C code of MqS using the following statement
context-self = PyObject_GC_New(PyObject,(PyTypeObject*)context-class);
class is the Server but the PyMqS_new is *not* called as expected
- Why ?
4. I checked the code with a debugger and I find out that the python
ServerObject create with PyObject_GC_New has the right pointer
- ServerObject-ob_type-tp_new has a pointer to PyMqS_new
- this seems to be fine
I checked the tp_basicsize and this has a size of 40 seems ok
from: http://docs.python.org/3.0/extending/newtypes.html
If you want your type to be subclassable from Python, and your type has the
same tp_basicsize as its base type, you may have problems with multiple
inheritance. A Python subclass of your type will have to list your type
first in its __bases__, or else it will not be able to call your type’s
__new__() method without getting an error. You can avoid this problem by
ensuring that your type has a larger value for tp_basicsize than its base
type does. Most of the time, this will be true anyway, because either your
base type will be object, or else you will be adding data members to your
base type, and therefore increasing its size.
An other aspect from your docu (same link as above):
If you are creating a co-operative tp_new (one that calls a base type’s
tp_new or __new__()), you must not try to determine what method to call
using method resolution order at runtime. Always statically determine what
type you are going to call, and call its tp_new directly, or via
type-tp_base-tp_new. If you do not do this, Python subclasses of your
type that also inherit from other Python-defined classes may not work
correctly. (Specifically, you may not be able to create instances of such
subclasses without getting a TypeError.)
This I don't understand because the tp_base of MqS is Object
and if I call the Object tp_new from my new
static PyObject *
PyMqS_new(PyTypeObject *type, PyObject *args, PyObject *kwds)
{
M0
?? type-tp_base-tp_new(
PyMqS_Obj *self = (PyMqS_Obj *)type-tp_alloc(type, 0);
self-msgque = NULL;
return (PyObject *)self;
}

Re: who is calling the base class __new__ method
Hi, found a solution - PyObject_GC_New seems not to be *not* the right function to create a new Python object with a base class included - PyType_GenericNew is the right one ... but this one is not documented from: http://docs.python.org/3.0/c-api/type.html = PyObject* PyType_GenericNew(PyTypeObject *type, PyObject *args, PyObject *kwds)¶ Return value: New reference.

best void return of a member function
Hi, I'm writing a native language binding for a library. http://libmsgque.sourceforge.net/ Every native method called by PYTHON have to return a PyObject* even if the function itself does not return anything. I have 2 possibilities for return a PyObject* 1. the first argument of the method function - return self; 2. an entire new empty object - return Py_BuildValue(); Question: what is the best return statement for a void function ?

[...] Question: what is the best return statement for a void function ? Hmmm, this sounds like your goal is to write an exact 1:1 wrapper of the C library API (for which there are tools like SWIGfriends). If the library happens to have a rather unusual, close-to object oriented, high-level C API, that might work. Otherwise, you might want to try to wrap it in a more Pythonic lookfeel style, that wraps operations and use-cases rather than plain functions. That should make it easier to hide things like memory allocation and other C implementation details from users, and will generally increase the performance of your binding, as it will require less calls for larger operations in C space. Stefan Thanks for your help .. I'm almost finished ... it took me ~1week from a non Python developer to: 1. download, install python 2. learn how to use python, syntax, class, objects, protocol, ... 3. learn how to use the native interface, ~hundreds of C functions 4. finally create a project add my native code, compile, build ... test - I just add one extra type I call them PyMqS_type all the special tools are not necessary because if you wrote one language interface you can write every language interface - the tasks are allways the same... just the language-specific-names are changing mfg Andreas Otto -- http://mail.python.org/mailman/listinfo/python-list

Re: Question to python C API
Hi,
just my first step in Cython
1. download Cython-0.11.1
2. read INSTALL.txt
(1) Run the setup.py script in this directory
as follows:
python setup.py install
This will install the Pyrex package
into your Python system.
Question 1: Why you wall it Pyrex package ?
3. this happen
python ./setup.py install
Traceback (most recent call last):
File ./setup.py, line 5, in module
from Cython.Compiler.Version import version
File /home/dev1usr/src/Cython-0.11.1/Cython/__init__.py, line 2, in
module
from Shadow import *
ImportError: No module named Shadow
4. I use a thread enabled python V3
Question 2: What I have to do ?
4. than I try the second part from INSTALL.txt
(2) If you prefer not to modify your Python
installation, arrange for the directory
containing this file (INSTALL.txt) to be in
your PYTHONPATH. On unix, also put the bin
directory on your PATH.
5. and start to build the hello world example
I changed: print Hello World
to: print(Hello World)- this is V3
6. but got the following error
cat setup.py
from distutils.core import setup
from distutils.extension import Extension
from Cython.Distutils import build_ext
setup(
cmdclass = {'build_ext': build_ext},
ext_modules = [Extension(pymsgque, [helloworld.pyx])]
)
python setup.py build_ext --inplace
Traceback (most recent call last):
File setup.py, line 3, in module
from Cython.Distutils import build_ext
ImportError: No module named Cython.Distutils
7. a little bit to much errors for the first step, isn't it ?

Re: Question to python C API
Yes, you are right ... I read more and found the doc about this ... the problem I have is something more tricky ... I allready have an extension written for java and the easyest thing would be use this as template and replace the java specific calls with python calls ... but the python C API is much more complex than java JNI. I don't understand why because the task is allways the same the problem is that i have a C api but don't want to use a 1 to 1 translation of the C functions to python. java generate the stub with java.h and you have to fill the stub with code even if it is just a function call of a C api function with near the same name. for me as user I would prefer the exact same way in python to: 1. write a python wrapper class 2. declare all external function with native 3. call python_h to create the necessary C header 4. and let the user bill the body 5. this require to have a clean and small language native interface (JNI fit on one web page that's it) but i have helper functions which , for example, create threads and python module have to attach to this thread. the problem with such kind of framework is usually that you start with the easy stuff and than (after a couple of days/weeks) you come to the difficult stuff and you have to figure out that this kind of problem does not fit into the tool. stuff what I do is: 1. create objects on the fly as connection handle 2. do callbacks from C to Python 3. create and delete threads or manage to continue work after an fork 4. is server mode start an event-loop and never come back what I want: I want to use this tool but still be able to intermix parts of my C helper code with the python code question: it is possible to write C and python code into the same file ? -- http://mail.python.org/mailman/listinfo/python-list

Hi, I'm a the maintainer for the new project 'libmsgque' hosted at SF (see below for details) and need a volunteer to develop the language bindings for python. Is somebody available to take over this job ? An example language binding for tcl is allready available. This is the initial announcement: ANNOUNCE: libmsgque2.3-beta2 The libmsgque project is an infrastructure for linking applications together to act like a single application. This is done using Unix or inet domain sockets. The framework handles all aspects of setting up and maintaining the link in addition to starting and stopping the different applications, starting and stopping the communication interface, sending and receiving packages, reading and writing data from or into packages, setting up and maintaining the event handling for asynchronous transfers, and propagating warnings or errors. WHERE TO GET As usual, it is available from: http://libmsgque.sourceforge.net/ http://sourceforge.net/projects/libmsgque/ WHAT'S NEW == This is the initial announcement WHAT IS IT == First of all it is a framework to link commands together to avoid the traditional shell pipline using a similar approach as MS PowerShell.
