- cleanup virtualenv creation code
- ensure all testing virtual environments use a recent version
of setuptools / wheel, making it easier to switch to custom
versions of those, as well as reducing network accesses
- reduce size of testing virtual environment, slightly speeding
up the testsuite
This essentially allows me to do an overall check general check by running the tests using pytest's `-k basic` syntax. Given that I like running tests often and that, in general, I make typos more often than changes that break core functionality, I think this will reduce cycle times for me.
* Showed installers when list command runs with -vv option
* Added news entry
* Updated code to show both location and installer of a package when '-v' is used
* Removed installer from freeze format
* Moved get_installer function to pip.utils.packaging
* Move virtualenv creation out of TestPipEnvironment
* Remove global state and force explicit use of TestPipEnvironment
instances
* Remove "backup" virtualenv copying and instead create new
virtual environments each time.
* Remove the monkeypatched "PyPICache" functionality
* Remove things that were not being used anymore and were dead
weight
* Remove sitecustomize support which was primarily used to
monkeypatch the "PyPICache" but was used in one or two other
tests.
