I am researching issues related to emdedding Python in C++ for a
project.
My project will be running on an SMP box and requires scalability.
However, my test shows that Python threading has very poor performance
in terms of scaling. In fact it doesn't scale at all.
I wrote a simple test program to complete given number of iterations
of a simple loop. The total number of iterations can be divided evenly
among a number of threads. My...

I've embedded python in a threaded app which contains two threads that may
call into Python. The threads are created via the "C" api. If I can
guarantee (1) that no python API is ever called at the same time from the
two threads, is it necessary to init threads/aquire locks etc
(PyEval_InitThreads, PyEval_AcquireThread and friends)?
The reason (2) I ask this is that I'm afraid that the locking takes some
time. Is this concern justified?...

I am embedding python in my C++ application. I am using Python *2.3.2* with
a C++ extention DLL in multi-threaded environment. I am using SWIG-1.3.19 to
generate C++ to Python interface.
Now to explain it in details,
1. Python initialization and finalization
is done in the *main* thread.
2. For each new thread I create a separate sub-interpreter
.
3. Using PyRun_String("import myModule"...) before execution of python

Here is my problem.
I have this library thats hosts another language within python, and
allows that language to call back INTO python.
All is good as long as the other languages calls back on the same
thread. If the callback arrives on a different thread, all hell break
loose and the program dies horribly.
looking at the C api documentation, I came upon the following block of

Greetings,
I am new to python and wish to embed python in an 3D graphics
application to provide application automation. The high level goal is to
be able to drive my app from a script for batch job like behavior rather
than via the GUI (ie. I would like to run a script and see those changes
reflected in the GUI as if the user had clicked buttons, etc.) The
application is written in C++ and uses QT for the GUI.
I have read the python...

Hello,
I am embedding a python script in a C++ application. The script can be
called simultaneously from multiple threads.
What is the correct way to implement this situation:
1) Have unique python interpreter instantiations ( Py_Initialize() ) for
each thread.

I've tried embedding Python in a C app so that Threading is done in the
Python side.
In the simple example below, unless I uncomment the ALLOW_THREADS macros,
the Python thread does nothing until the C for-loop finishes.
My real-world example is a large C/Motif application - apart from scattering
the ALLOW_THREADS macros everywhere (and what do you do while the Motif
event loop is idling?), is there a better way to get the Python...

Hi :)
I want to run Python in my app. That works still fine. But my app
supports now Threads and I would like to know what to do, that it runs
without problems.
PyGILState_Release and PyGILState_Ensure should solve the problem
right? Where do I have to put this two commands around? between each
Command that increase, decrease a reference?

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...
