d93b7a9eae Correct EXTENDED_ARG handling on Python 3.6...
where it can appear several times and xdis may handle it as well.
It possibly in other versions bug since EXTENDED_ARG is used so rarely
there because it has such a high value 1<<16, it's hard to test and
determine that.

b4efa62fad EXTENDED_ARG handling...
get_target() wasn't taking into account EXTENDED_ARG before opcode.

This is mostly relevant in Python 3.6 where the max size before needing
EXTENDED_ARG has been reduced to 256, but theoretically possible in earlier
versions.

3b1dd9d1c4 added property based test for verifying uncompylation of function calls. A number of minimal examples for the various function call opcodes have been generated with the majority marked as expected failure until python 3.6 opcode support is complete.

* uncompyle6/scanners/scanner3.py: Correct EXTENDED_ARG handling on
Python 3.6... where it can appear several times and xdis may handle it as well.
It possibly in other versions bug since EXTENDED_ARG is used so
rarely there because it has such a high value 1<<16, it's hard to
test and determine that.

handling

* uncompyle6/parsers/parse36.py, uncompyle6/scanners/scanner3.py:
EXTENDED_ARG handling... get_target() wasn't taking into account EXTENDED_ARG before opcode. This is mostly relevant in Python 3.6 where the max size before
needing EXTENDED_ARG has been reduced to 256, but theoretically
possible in earlier versions.

* uncompyle6/parsers/parse36.py: More EXTENDED_ARGS on 3.6
2017-05-16 rocky <rb@dustyfeet.com>
* uncompyle6/parsers/parse36.py: extend use of EXTENDED_ARGS in 3.6 switching to a wordcode seems to have made opcode fields smaller so
we need EXTENDED_ARG more?

# How to report a Bug
## The difficulty of the problem
There is no Python decompiler yet, that I know about that will
decompyle everything. This one probably does the
best job of *any* Python decompiler. But it is a constant work in progress: Python keeps changing, and so does its code generation.
I have found bugs in *every* Python decompiler I have tried. Even
those where authors/maintainers claim that they have used it on
the entire Python standard library. And I don't mean that
the program doesn't come out with the same Python source instructions,
but that the program is *semantically* not equivalent.
So it is likely you'll find a mistranslation in decompiling.
## What to send (minimum requirements)
The basic requirement is pretty simple:
* Python bytecode
* Source text
## What to send (additional helpful information)
Some kind folks also give the invocation they used and the output
which usually includes an error message produced. This is helpful. I
can figure out what OS you are running this on and what version of
*uncomplye6* was used. Therefore, if you don't provide the input
command and the output from that, please give:
* _uncompyle6_ version used
* OS that you used this on
* Python interpreter version used
### But I don't *have* the source code!
Sure, I get it. No problem. There is Python assembly code on parse
errors, so simply by hand decompile that. To get a full disassembly,
use pydisasm from the [xdis](https://pypi.python.org/pypi/xdis)
package. Opcodes are described in the documentation for
the [dis](https://docs.python.org/3.6/library/dis.html) module.
### But I don't *have* the source code and am incapable of figuring how how to do a hand disassembly!
Well, you could learn. No one is born into this world knowing how to
disassemble Python bytecode. And as Richard Feynman once said, "What
one fool can learn, so can another."
## Narrowing the problem
I don't need the entire source code base for which one file or module
can't be decompiled. I just need that one file or module only. If
there are several files, file a bug report for each file.
Python modules can get quite large, and usually decompilation problems
occur in a single function or maybe the main-line code but not any of
the functions or classes. So please chop down the source code by
removing those parts that do to decompile properly.
By doing this, you'll probably have a better sense of what exactly is
the problem. Perhaps you can find the boundary of what decompiles, and
what doesn't. That is useful. Or maybe the same file will decompile
properly on a neighboring version of Python. That is helpful too.
In sum, the more you can isolate or narrow the problem, the more
likley the problem will be fixed and fixed sooner.

* https://github.com/zrax/pycdc : supports all versions of Python and is written in C++. Support for later Python 3 versions is a bit lacking though.
* https://code.google.com/archive/p/unpyc3/ : supports Python 3.2 only. The above projects use a different decompiling technique than what is used here.
* https://github.com/figment/unpyc3/ : fork of above, but supports Python 3.3 only. Include some fixes like supporting function annotations
* The HISTORY_ file.
