Stackless 3.0 for Python 2.3: new binaries

[Christian Tismer]

New Win32 binaries have been uploaded to the Stackless website.

Some compatibility issues with certain constructors
have been solved.

Please let me know of any problems.

more to come soon - cheers -- chris

Trying seriously to find out how to use stackless and what it is
good for ;-), I stumbled just in the beginning. While I was able to
execute some of my Python programs, among them Tkinter-programs
and even recursive ones,

(1) I was not able to use Stackless from IDLE:

Python 2.3.3 Stackless 3.0 040221 (#51, Feb 15 2004, 22:37:26) [MSC
v.1200 32 bit (Intel)] on win32
Type "copyright" , "credits" or "license()" for more information.

(2) I don't know where to put python23.exp (and what it is good
for). Maybe this is the reason for problem (1) ??

Alaaf, you are cheating, right?
You must have known, partially, last August. ;-)

Yes, I tried this and I get the same problem.
Have to admit that I'm not a regular IDLE user.
Seriously, I have no idea what's going on.
Seriously, I have also no idea why Python must
try to pickle something, to compute 3*4 ???

Everything works with Python 2.2. I expect something
has changed dramatically with Idle, and there is some
compatability issue with all the new pickling support that
we had to add for Python 2.3. Eeek, how do I debug that!

Forget it. it is just a table of exported names which might help
with debugging.

I'm no IDLE or Tcl/Tk user, either. But I had Tcl problems,
before. What I really would hate is to have to build the Tcl
stuff and debug that.
What I'm probably going to try tomorrow is to disable all
pikcling extensions at all and see if it runs, then.
Then I will re-enable them, one after the other.
My guess is that something gets pickled because it shows
up as pickleable, through introspection.
Maybe a special case is hit again (like with cell objects)
that needs to use the ternary __reduce__ protocol. I don't know.

I need sleep. ciao - chris

OK got it: It must be functype which tends

This works:

return 0;
}

So I think I have to change pickling of functions and we are there.
I guess this is not a Tkinter issue, but it would have hit us
at some time, later.

good night finally! :-) chris

(yes, hacks like this are my strength)

Hey, this is a hit!
First result: It works, if we do this:

int init_prickelpit (void)
{
if (0
// || init_codetype()
// || init_functype()
// || init_celltype()
// || init_frametype( )
// || init_tracebackt ype()
// || init_moduletype ()
|| init_moduledict type()
// || init_itertype()
// || init_methodtype ()
// || init_generatort ype()
// || init_dictiterty pe()
|| init_enumtype()
|| init_enumfactor ytype()
// || init_listiterty pe()
// || init_rangeitert ype()
// || init_tupleitert ype()
) return -1;
return 0;
}

I will uncomment stuff tomorrow, then we'll see :-))

Stackless update (was: [Stackless] Re: Stackless 3.0 for Python 2.3:new binaries)

Issue solved.
Stackless works fine with IDLE, now.
This was not IDLE-specific, but a forgotton adaption of
cPickle to Stackless.
At the same time, a real cPickle bug showed up, and I submitted
a patch.

If there are no further bugs showing up, I wish to freeze
Stackless for three weeks. Development will continue on
the Stackless Sprint in Berlin, March 10-14.

See the updated website at http://www.stackless.com/
