retrieve source for py2exe application

retrieve source for py2exe application

retrieve source for py2exe application

(OP)
Greetings all,

We're trying to retrieve the code for an old python 2.4 program that was converted into a single-file executable using py2exe.
Programmer left without updating the files in SVN.

Using Seven Zip, I was able to retrieve from the .EXE file the *.pyo files for the imported modules.
(The main script however is not so easily retrieved.)

These .PYO files convert easily back to the .PY source using easypythondecompiler.

Using resourcesviewer, I am able to retrieve what I thought was the main script.

However, easypythondecompiler complains with "Invalid pyc/pyo file - Magic value mismatch!"
leading me to think I "retrieved" the main script incorrectly.

Do you have any idea that may help?

getting closer... following the code at build_exe.py of the py2exe package I got the following

CODE --> python

import inspect
import marshal

p = r"C:\Users\justin\Desktop\processdownloadedfiles_pythonscript_1.bin"
f = open(p, 'rb')
s = f.read()
f.close()

o = marshal.loads(s[17:-2])
print o
code = o[-1]
print dir(code)

x = marshal.dumps(code)
print len(x)
pp = r"C:\Users\justin\Desktop\processdownloadedfiles.pyc"
f = open(pp, 'wb')
f.write(x)
f.close() 

however, easypythondecompiler still complains with the same error.
now to figure out how to turn a code object (see code variable above) back to source or to a proper .PYC file.
