* Test cache argument of Request.get_json
* Ignore cache on request.get_json(cache=False) call
Removes usage of `_cached_json` property when `get_json` is called with
disabled cache argument. (closes#2087)
Without this, the LICENSE file is never included in the built wheels: this makes it harder for users to comply with the license.
With this addition a file LICENSE.txt will be created in the `xxx.dist-info` directory with the content of the `license_file` file, e.g. the top level LICENSE.
It is entirely sufficient to walk the MRO of the exception class, no need to check for classes re-appearing later on, no need to add the MRO of any superclass.
* Python refuses point-blank to create a class with a circular MRO.
* All classes in a superclass MRO *already* appear in the MRO of the derived type. Re-adding the contents of a superclass MRO is doing double work.
* Add init to FlaskClient
This addresses #1467. The init in the subclass
can now take in `environ_base`, which will then get
passed to `make_test_environ_builder` and to
`EnvironBuilder` via keyword args.
This should provide the default environment capability
on `app.test_client()` init.
* Add kwarg `environ_base` to `make_test_environ_builder` call
This change now passes `environ_base` from either
`kwargs` in `FlaskClient.open` or `FlaskClient.environ_base`
if passed into the init.
* Fix assignment reference typo
* Add default `environ_base` to `FlaskClient.__init__`
* Set default kwargs for `environ_base` in `FlaskClient.open`
* Remove specific environ_base kwarg since its in kwargs
* Add docstring to FlaskClient detailing environ_base
* Document app.test_client default environ in CHANGES
* Re-word environ_base changes in FlaskClient docstring
* Add client.environ_base tests
* Mention preset default environ in `app.test_client`
* Add versionchanged directive to docstring in FlaskClient
* Remove `-a/--app` from Quickstart documentation
As mentioned in #2009, simplifying the CLI saw the removal of the `-a/--app` flag. Therefore, the only way to specify the module to import is by setting `FLASK_APP`.
* Remove misleading `either` from CLI help
The CLI help details how to run the application, but still uses the phrasing "either through the `FLASK_APP`...". This likely is an artifact from when `-a/--app` was still present in the CLI.
* Distinguish between directories and files
* Convert larger apps to make use of setup.py
- replaces runserver.py with setup.py
- example now runs with recommended structure
* Fixes a typo and formats the added paragraph
