This allows for async functions to be passed to the Flask class
instance, for example as a view function,
@app.route("/")
async def index():
return "Async hello"
this comes with a cost though of poorer performance than using the
sync equivalent.
asgiref is the standard way to run async code within a sync context,
and is used in Django making it a safe and sane choice for this.
This takes a popular API whereby instead of passing the HTTP method as
an argument to route it is instead used as the method name i.e.
@app.route("/", methods=["POST"])
is now writeable as,
@app.post("/")
This is simply syntatic sugar, it doesn't do anything else, but makes
it slightly easier for users.
I've included all the methods that are relevant and aren't auto
generated i.e. not connect, head, options, and trace.
The implementations were moved to Werkzeug, Flask's functions become
wrappers around Werkzeug to pass some Flask-specific values.
cache_timeout is renamed to max_age. SEND_FILE_MAX_AGE_DEFAULT,
app.send_file_max_age_default, and app.get_send_file_max_age defaults
to None. This tells the browser to use conditional requests rather than
a 12 hour cache.
attachment_filename is renamed to download_name, and is always sent if
a name is known.
Deprecate helpers.safe_join in favor of werkzeug.utils.safe_join.
Removed most of the send_file tests, they're tested in Werkzeug.
In the file upload example, renamed the uploaded_file view to
download_file to avoid a common source of confusion.
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.
- pytest 5.x drops python2 compatibility and therefore only implements PEP 451
- pytest 5.x made the repr of `ExcInfo` less confusing (fixed tests depending
on the old format)
