Python Version: 2.6a1 where to get this?

[RobinVossen]

Hello all,

I am trying to disassemble some Python Bytecode with dis.dis and this is really though.
So here is a little look into my Journey!

% python -V
Python 2.6.5
% python
Python 2.6.5 (r265:79063, Mar 23 2010, 04:49:54)
[GCC 4.4.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import dis
>>> import base64
>>> dir(base64)
['EMPTYSTRING', 'MAXBINSIZE', 'MAXLINESIZE', '__all__', '__builtins__', '__doc__', '__file__', '__name__', '__package__', '_b32alphabet', '_b32rev', '_b32tab', '_translate', '_translation', '_x', 'b16decode', 'b16encode', 'b32decode', 'b32encode', 'b64decode', 'b64encode', 'binascii', 'decode', 'decodestring', 'encode', 'encodestring', 'k', 're', 'standard_b64decode', 'standard_b64encode', 'struct', 'test', 'test1', 'urlsafe_b64decode', 'urlsafe_b64encode', 'v']
>>> dis.dis(base64.decode)
302 0 SETUP_LOOP 64 (to 67)
>> 3 LOAD_GLOBAL 0 (True)
6 JUMP_IF_FALSE 56 (to 65)
9 POP_TOP
<More Byte Code this works fine>
% ls
download.pyc
% python
Python 2.6.5 (r265:79063, Mar 23 2010, 04:49:54)

>>> import download.pyc
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: Bad magic number in download.pyc

So I went out googling
And I read this sourcefile:
[projects] View of /python/trunk/Python/import.c

And I figured how it worked thus I used radare to figure-out the Magic by hand.
I used this sourcefile to figure out what version of Python the Bytecode was coded :

#include <stdio.h>

/* Version 2.6a1 */
#define MAGIC (62161 | ((long)'\r'<<16) | ((long)'\n'<<24))

static long pyc_magic = MAGIC;

int main(int argc, char **argv)
{
   printf ("%8x\n",pyc_magic);
   return 0;
}

And that was Right (took me a while till I got the right Magic..
Anyway, To make a long story short.
I want to manage to get Python 2.6a1 on my Linux box. Where can I get this?
As on the Python webpage it does just say:

Python 3.1.2 (March 21st, 2010)
Python 3.0.1 (February 13, 2009)
Python 2.6.5 (March 19, 2010)
Python 2.5.5 (January 31, 2010)
Python 2.4.6 (December 19, 200
Python 2.3.7 (March 11, 200
Python 2.2.3 (May 30, 2003)
Python 2.1.3 (April 8, 2002)
Python 2.0.1 (June 2001)
Python 1.6.1 (September 2000)
Python 1.5.2 (April 1999)

So no 2.6.1..
So who has this can tell me where to get this?


Thanks

Cheers,
Robin
