Port to python3 [$20]

[vtemian]

Gitfs was written using only Python 2 code, but now, as the things in Python 3 evolves and are very stable, we need to port our Python 2 code to Python 3 compatible code.

Did you help close this issue? Go claim the $20 bounty on Bountysource.

This will probably rise some issues after the update for things not covered in the tests. I will give it a go this week. It should be both 2.7 and 3.4 compatible, right?

I will work on this in this week. Can you have any suggestions for me? Thanks
For now i found some compatibility issues with octal numbers which is used for permissions.
I also found another compatibility issues such as urlparse and Queue, and solved that.

Hi guys,

@cdvv7788 yep, 3.4 sounds great.
@goranpavlovic you can find some tools and articles online:

• https://docs.python.org/2/howto/pyporting.html
• pylint has a special mode --py3k in which it will show you some compatibility problems

[goranpavlovic]

I have solved some of problems.

1. Compatiblity issue with python basestiring function, python3 does not have defined this function.
2. Compatibility issue with timestamp.
3. Compatibility issue with iteritems function.
4. Issues with different way to use octal numbers in python2 and python3 which you use for permissions.
5. Different way for using urllib functionality.
6. Issue with queue class in python versions 2 and 3.

After that changes
I have installed application normally to python3 virtual environment.
Also application is successfully started.

But i just have one problem for now , when i go to directory which is mounted using gitfs
and on index route try to get list of files with command ls or ls -als
i get this error:
ls: reading directory .: Function not implemented
total 0

But in index view and in python2.7 environment i see that output should be ['.', '..', 'current', 'history']

Function readdir is not called.

I assume that i have compatibility issue with some interfaces or classes such as
some method name was changed or something like that.

I will continue work on this problem.

I forgot to say this, i am working with python 3.4

Thanks

Hi, I've created a solution with #212, it includes working tests both on drone and vagrant.
