tests: add test for Python 3 compatibility
Python 3 is inevitable. There have been incremental movements towards
converting the code base to be Python 3 compatible. Unfortunately, we
don't have any tests that look for Python 3 compatibility. This patch
changes that.
We introduce a check-py3-compat.py script whose role is to verify
Python 3 compatibility of the files passed in. We add a test that
calls this script with all .py files from the source checkout.
The script currently only verifies that absolute_import and
print_function are used. These are the low hanging fruits for Python
compatbility. Over time, we can include more checks, including
verifying we're able to load each Python file with Python 3. You
have to start somewhere.
Accepting this patch means that all new .py files must have
absolute_import and print_function (if "print" is used) to avoid
a new warning about Python 3 incompatibility. We've already
converted several files to use absolute_import and print_function
is in the same boat, so I don't think this is such a radical
proposition.

# highlight - syntax highlighting in hgweb, based on Pygments # # Copyright 2008, 2009 Patrick Mezard <pmezard@gmail.com> and others # # This software may be used and distributed according to the terms of the # GNU General Public License version 2 or any later version. # # The original module was split in an interface and an implementation # file to defer pygments loading and speedup extension setup. """syntax highlighting for hgweb (requires Pygments) It depends on the Pygments syntax highlighting library: http://pygments.org/ There are the following configuration options:: [web] pygments_style = <style> (default: colorful) highlightfiles = <fileset> (default: size('<5M')) highlightonlymatchfilename = <bool> (default False) ``highlightonlymatchfilename`` will only highlight files if their type could be identified by their filename. When this is not enabled (the default), Pygments will try very hard to identify the file type from content and any match (even matches with a low confidence score) will be used.
