            Bug ID: 24461
           Summary: Allow LLDB to support Python 3.5
           Product: lldb
           Version: unspecified
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal

In Bug 21920 a problem is described that makes Python very difficult to use on
Windows.  Python 3.5 on Windows is implemented in such a way as to be forward
compatible with future versions of Visual Studio.  As a result, we've decided
that the best way forward is to allow LLDB to support Python 3.5.  Since there
are already potentially hundreds of thousands of lines of Python code written
against 2.7, we will need to do this in such a way that LLDB supports *both*
Python 2.7 and Python 3.5+.

The biggest difficulty and pain point arising from this will be the need for
the test suite and all specific tests to be written using a subset of Python
that will work in both 2.7 and 3.5.

In order to ensure this requirement is met, part of this task will involve
setting up at least two build bots: one that runs tests using 2.7 and another
that runs tests using 3.5.
