uncompyle2's Issues

Unable to decompile this simple code

First of all I must admit this decompiler is the best I've ever tested, great readality and debuggable, nice work, guys!
But here is a very simple section that current build can't pass through, I don't know a lof on byte-code, but I believe it's a bug, any question please contact me in: [email protected]

source:

selection = []
allEdges2

def findVerts( selection ):
    allEdges2 = ['AAA', 'BBB', 'CCC']
    templates2 = ['A', 'B', 'C']
    cdEdgeLength2 = [floorMe( e.lower() ) for e in allEdges2]
    for i in range( len( templates2 ) ):
        if cdEdgeLength2[0] == templates2[i] :
            if selection:
                selection.append( e.lower() )

def floorMe( stringX ):
    return stringX

Failure when decompiling a conditional generator, python 2.5

Current version of uncompyle2 fails to handle the following piece of code compiled with Python 2.5:

a=[1,2,3]
b=(1 for i in a if i)

The corresponding bytecode:

  3           0 SETUP_LOOP              29 (to 32)
              3 LOAD_FAST                0 (.0)

There are 2 issues here:

• scanner for Python 2.5 is supposed to strip away SETUP_LOOP and POP_BLOCK, but it fails to do it
• there's no grammar production with double JUMP_BACK

local variable 'n' referenced before assignment

Hi, i got this error when i use uncompyle2:

Traceback (most recent call last):

This pyc code is written with python 2.6. Can you help fix this? Thanks

Support for 2.6 .pyc file ?

Hi,

Just tried to uncompile a 2.6 .pyc file and it said me that only 2.7 is supported. The tool is ran under python 2.7 env.

Here is the "suspect" code found :
if version != '2.7':
raise ImportError, "This is a Python %s file! Only Python 2.7 files are supported." % version
#print version

The "magic" of my 2.6 .pyc file is found, but the code upper doesn't handle it.

Is the support for 2.6 abandoned ? Or, should I force the feature to translate the bytecode to 2.7, than decompyle it ?

Cheers,

Phil

wildfire breaks uncompyle2

Hi Mysterie,

Recently I have been playing on with Python bytecodes to do weird stuff for fun, and I just saw the python-compiled file I am generating seem to break uncompyle2.

Also, if you want to see how those files are generated, see wildfire.py: https://github.com/0vercl0k/stuffz/blob/master/Python's%20internals/wildfire.py

Feel free to email me if you don't manage to reproduce the Python traceback!

multiple uncompyle2 issues: gstarnberger/uncompyle2 #17-30

There are a number of bugs in the unmaintained forks of uncompyle2. I'd like folks to know what those issues are but reporting them in all the forks is a bit tedious. Details can be found in
https://github.com/gstarnberger/uncompyle/issues

Periodically I'll up date the numbers in the title.

Get error: TypeError: main() takes at most 8 arguments (10 given)

HI, everyone:

I try to install uncompyle2 by using "python setup.py install"

and after that I use "uncompyle2 file.pyc" to decompile.

BUT I got this error:
#2013.12.30 11:26:17 CST

Traceback (most recent call last):
File "/usr/local/bin/uncompyle2", line 166, in
showasm, showast, do_verify, py, deob)
TypeError: main() takes at most 8 arguments (10 given)

My OS is Ubuntu13.10. May anyone offer me some tips to address this problem?

Thanks!!

Python 2.5 scanner incorrectly restructures the code after deleting instructions

I believe the following fragment of Scanner25.py is wrong:

            for x in toDel:
                if self.code[x-delta] >= dis.HAVE_ARGUMENT:
                    self.code.pop(x-delta)
                    self.restructCode(x-delta)
                    self.code.pop(x-delta)
                    self.restructCode(x-delta)
                    self.code.pop(x-delta)
                    self.restructCode(x-delta)
                    delta += 3
                else:
                    self.code.pop(x-delta)
                    self.restructCode(x-delta)
                    delta += 1

For 3-byte instructions it tries to restruct the code after each byte removed - thus, if e.g. restructCode is called after the first byte is removed, it will treat second byte of the instruction as opcode.

The call to restructCode() should be done only once, after removing all 3 bytes. However, this means that restructCode() need to know if 1 or 3 bytes were removed.

Can't get uncompyle2 to work on windows 8

ive seen this problem on your github error page, but it was closed and marked as error 34 which inturn linked to error 37.

could i get som info on how to solve this?

whatever the file I want to decompile, i gives this.
the "testpythonlib.py" seems to work but I cannot adapt it to try to decompile my files

any tips ?

if there are many LOAD_CONST in the opcode , it cannot work!

uncompyle2 cli

cannot decompile to the source code

uncompyle2 --py -o . xxx.pyc

It will be no responding, and CPU go to 100%, memory also be full filled

2.4 Support?

Hey, not exactly sure where to post this so I figured I'd make an issue. Is 2.4 support planned to be made? I have a project that requires a TON of bytecode to be decompiled, and uncomyple2 has never failed me with 2.7. If this could be available on 2.4, it'd probably be the best decompiler out there.

I have tried decompyle++ and a few others, none of them ever decompile anything as nicely as uncomyple2. If there isn't support for this planned, do you know of any decompilers that'll do the job well?
