Flask's client.open mirrors Werkzeug's for processing an existing
environ.
Always test with latest code for other Pallets projects. This will
be changed back once the new versions are released.
Flask instances with static folders were creating a reference cycle
via their "static" view function (which held a strong reference back
to the Flask instance to call its `send_static_file` method). This
prevented CPython from freeing the memory for a Flask instance
when all external references to it were released.
Now use a weakref for the back reference to avoid this.

Commit 2ae740dd49 probably inadvertently
changed to iterate over a set of "create_app", "make_app" to discover
application factory functions. As sets don't guarantee order,
differences in the implementation of the type can make it
non-deterministic which factory function is used if a project implements
both. Revert to using a tuple.

When loading the app fails for the --help command, only the error
message is shown, then the help text. The full traceback is shown for
other exceptions. Also show the message when loading fails while
getting a command, instead of only "command not found". The error
message goes to stderr to match other error behavior, and is in red
with an extra newline to make it more obvious next to the help text.
Also fixes an issue with the test_apps fixture that caused an imported
app to still be importable after the test was over and the path was
reset. Now the module cache is reset as well.
* No longer causes AttributeError: 'PosixPath' object has no
attribute 'rstrip'.
* This was broken by e6178fe489
which was released in 1.1.2.
* Add a regression test that now passes.
See #3557.
