Hi all,
After some research I've decided that my previous question (Confusing
problem between Tkinter.Intvar...) was headed in the wrong direction.
Partly because I think I have a greater understanding of what was
happening, and partly because pickling Tkinter widgets is an issue
that seems to have been touched on over the years but never really
acted on.
Postings back to '96 have talked about the need to pickle Tk widgets.

I'm having trouble pickling subclasses of dict when they contain cycles.
In particular:
>>> import pickle
>>> class D(dict): pass
>>> d = D()
>>> d = d # add a cycle.
>>> print d
{1: {...}}
>>> pickle.dump(d, open('d.pickle', 'w'))

I have a class that inherits from PyGTK's gobject.GObject. I thought to
pickle it I'd be able to just define __etstate__ methods. When I
attempt to dump an instance of this class I get a TypeError from
copy_reg._reduce_ex telling me that GObject.__init__() takes no args but
that it was called with one arg. Here's a "hello world" example:
#!/usr/bin/env python
import pickle

Dear all,
I have a long running application (electromagnetic compatibility
measurements in mode-stirred chambers over GPIB) that use pickle
(cPickle) to autosave a class instance with all the measured data from
time to time.
At the beginning, pickling is quite fast but when the data becomes more
and more pickling slows down rapidly.

Hi all, happy new year,
I was trying to pickle a instance of a subclass of a tuple when I ran
into a problem. Pickling doesn't work with HIGHEST_PROTOCOL. How should
I rewrite my class so I can pickle it?
Thanks ,
Fedor

Hi all,
I have a problem pickling an extension class. As written in the
Extending/Embedding Manual, I
provided a function __reduce__ that returns the appropreate tuple. This
seams to work fine,
but I still cannot pickle because of the following error:
>>> from model import hyper
>>> g = hyper.PeriodicGrid(4,4,1)

I've come across a limitation in unpickling certain types of complex
data structures which involve instances that override __hash__, and was
wondering if it was known (basic searches didn't seem to come up with
anything similar) and if there is a workaround for it short of
restructuring the data structures in question.
The fundamental issue rests with defining classes which override __cmp__
and __hash__ in order to be used as keys in...

Hi all,
I'm having a hard time resolving a namespace issue in my wsdl. Here's
an element that explains my question, with the full wsdl below:

If I gather correctly pickling an object will pickle its entire hierarchy,
but what if there are certain types of objects anywhere within the hierarchy
that I don't want included in the serialization? What do I do to exclude
them? Thanks.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

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...
