A lot of existing tarballs will successfully build a wheel, but the
wheel will be implicitly broken because they will have dynamically
adjusted the install_requires inside of their setup.py. Typically
this is done for things like Python version, implementation, or what
OS this is being installed on. We don't consider cache directories
to be OS agnostic but we do consider them to be Python version and
implementation agnostic. To solve this, we'll force the cached
wheel to use a more specific Python tag that includes the major
version and the implementation.
format_exc takes only one argument, limit which should be an integer.
python 2 seems more lenient than python 3 on that point.
mistake introduced in commit 3148b967a
The changes resolves a condition that can lead to a stacktrace due to the
use of constraint files. There are several conditions where the result
object may be left undefined which causes the problems.

This change simply ensures that the 'result' object is a defined

setuptools.package_index.local_open is used for file: URLs, and only
handles directories if the URL ends with a slash. Add the trailing
slash to pip's documentation to reduce confusion.
are unavailable, but issue a warning if this is used.
2. Explicitly handle the case where the unicode detection finds wide
unicode but this is a 3.3+ build (necessary due to #1)
3. Fix tests broken due to #2.
Pythons with PEP 393 Flexible String Representation (so >= 3.3).
Granted, on these Pythons, the SOABI config var should always be set,
but the manual SOABI code path should still try to do the right thing.
Additionally, fix the version portion of the Python tag on wheels built
with PyPy that use the Python API. It will now be the Python major
version concatenated with the PyPy major and minor versions.
Fixes#2671, #2882.
