* Mon Mar 28 2022 Michael Ströder - Update to 2.1.0
* Drop support for Python 3.6. #4335
* Update Click dependency to >= 8.0. #4008
* Remove previously deprecated code. #4337 - The CLI does not pass script_info to app factory functions. - config.from_json is replaced by config.from_file(name, load=json.load). - json functions no longer take an encoding parameter. - safe_join is removed, use werkzeug.utils.safe_join instead. - total_seconds is removed, use timedelta.total_seconds instead. - The same blueprint cannot be registered with the same name. Use name= when registering to specify a unique name. - The test client’s as_tuple parameter is removed. Use response.request.environ instead. #4417
* Some parameters in send_file and send_from_directory were renamed in 2.0. The deprecation period for the old names is extended to 2.2. Be sure to test with deprecation warnings visible. - attachment_filename is renamed to download_name. - cache_timeout is renamed to max_age. - add_etags is renamed to etag. - filename is renamed to path.
* The RequestContext.g property is deprecated. Use g directly or AppContext.g instead. #3898
* copy_current_request_context can decorate async functions. #4303
* The CLI uses importlib.metadata instead of setuptools to load command entry points. #4419
* Overriding FlaskClient.open will not cause an error on redirect. #3396
* Add an --exclude-patterns option to the flask run CLI command to specify patterns that will be ignored by the reloader. #4188
* When using lazy loading (the default with the debugger), the Click context from the flask run command remains available in the loader thread. #4460
* Deleting the session cookie uses the httponly flag. #4485
* Relax typing for errorhandler to allow the user to use more precise types and decorate the same function multiple times. #4095, #4295, #4297
* Fix typing for __exit__ methods for better compatibility with ExitStack. #4474
* From Werkzeug, for redirect responses the Location header URL will remain relative, and exclude the scheme and domain, by default. #4496
* Add Config.from_prefixed_env() to load config values from environment variables that start with FLASK_ or another prefix. This parses values as JSON by default, and allows setting keys in nested dicts. #4479
* Mon Feb 14 2022 Michael Ströder - Update to 2.0.3
* The test client\'s ``as_tuple`` parameter is deprecated and will be removed in Werkzeug 2.1. It is now also deprecated in Flask, to be removed in Flask 2.1, while remaining compatible with both in 2.0.x. Use ``response.request.environ`` instead. PR#4341
* Fix type annotation for ``errorhandler`` decorator. #4295
* Revert a change to the CLI that caused it to hide ``ImportError`` tracebacks when importing the application. #4307
* ``app.json_encoder`` and ``json_decoder`` are only passed to ``dumps`` and ``loads`` if they have custom behavior. This improves performance, mainly on PyPy. #4349
* Clearer error message when ``after_this_request`` is used outside a request context. #4333
* Tue Oct 05 2021 Stefan Schubert - Added BuildRequires: alts
* Tue Oct 05 2021 Michael Ströder - Update to 2.0.2
* Fix type annotation for teardown_
* methods. #4093
* Fix type annotation for before_request and before_app_request decorators. #4104
* Fixed the issue where typing requires template global decorators to accept functions with no arguments. #4098
* Support View and MethodView instances with async handlers. #4112
* Enhance typing of app.errorhandler decorator. #4095
* Fix registering a blueprint twice with differing names. #4124
* Fix the type of static_folder to accept pathlib.Path. #4150
* jsonify handles decimal.Decimal by encoding to str. #4157
* Correctly handle raising deferred errors in CLI lazy loading. #4096
* The CLI loader handles
*
*kwargs in a create_app function. #4170
* Fix the order of before_request and other callbacks that trigger before the view returns. They are called from the app down to the closest nested blueprint. #4229
* Sun Aug 22 2021 Stefan Schubert - Use libalternatives instead of update-alternatives.
* Sat Jun 19 2021 Michael Ströder - skip building for Python 2.x- updated upstream project URL- Update to 2.0.1
* Version 2.0.1 - Re-add the filename parameter in send_from_directory. The filename parameter has been renamed to path, the old name is deprecated. #4019 - Mark top-level names as exported so type checking understands imports in user projects. #4024 - Fix type annotation for g and inform mypy that it is a namespace object that has arbitrary attributes. #4020 - Fix some types that weren’t available in Python 3.6.0. #4040 - Improve typing for send_file, send_from_directory, and get_send_file_max_age. #4044, #4026 - Show an error when a blueprint name contains a dot. The . has special meaning, it is used to separate (nested) blueprint names and the endpoint name. #4041 - Combine URL prefixes when nesting blueprints that were created with a url_prefix value. #4037 - Roll back a change to the order that URL matching was done. The URL is again matched after the session is loaded, so the session is available in custom URL converters. #4053 - Re-add deprecated Config.from_json, which was accidentally removed early. #4078 - Improve typing for some functions using Callable in their type signatures, focusing on decorator factories. #4060 - Nested blueprints are registered with their dotted name. This allows different blueprints with the same name to be nested at different locations. #4069 - register_blueprint takes a name option to change the (pre-dotted) name the blueprint is registered with. This allows the same blueprint to be registered multiple times with unique names for url_for. Registering the same blueprint with the same name multiple times is deprecated. #1091 - Improve typing for stream_with_context. #4052
* Version 2.0.0 - Drop support for Python 2 and 3.5. - Bump minimum versions of other Pallets projects. - JSON support no longer uses simplejson. To use another JSON module, override app.json_encoder and json_decoder. #3555 - The encoding option to JSON functions is deprecated. #3562 - Passing script_info to app factory functions is deprecated. This was not portable outside the flask command. Use click.get_current_context().obj if it’s needed. #3552 - The CLI shows better error messages when the app failed to load when looking up commands. #2741 - Add sessions.SessionInterface.get_cookie_name() to allow setting the session cookie name dynamically. #3369 - Add Config.from_file() to load config using arbitrary file loaders, such as toml.load or json.load. Config.from_json() is deprecated in favor of this. #3398 - The flask run command will only defer errors on reload. Errors present during the initial call will cause the server to exit with the traceback immediately. #3431 - send_file() raises a ValueError when passed an io object in text mode. Previously, it would respond with 200 OK and an empty file. #3358 - When using ad-hoc certificates, check for the cryptography library instead of PyOpenSSL. #3492 - When specifying a factory function with FLASK_APP, keyword argument can be passed. #3553 - When loading a .env or .flaskenv file, the current working directory is no longer changed to the location of the file. #3560 - When returning a (response, headers) tuple from a view, the headers replace rather than extend existing headers on the response. For example, this allows setting the Content-Type for jsonify(). Use response.headers.extend() if extending is desired. #3628 - The Scaffold class provides a common API for the Flask and Blueprint classes. Blueprint information is stored in attributes just like Flask, rather than opaque lambda functions. This is intended to improve consistency and maintainability. #3215 - Include samesite and secure options when removing the session cookie. #3726 - Support passing a pathlib.Path to static_folder. #3579 - send_file and send_from_directory are wrappers around the implementations in werkzeug.utils. #3828 - Some send_file parameters have been renamed, the old names are deprecated. attachment_filename is renamed to download_name. cache_timeout is renamed to max_age. add_etags is renamed to etag. [#3828], #3883 - send_file passes download_name even if as_attachment=False by using Content-Disposition: inline. #3828 - send_file sets conditional=True and max_age=None by default. Cache-Control is set to no-cache if max_age is not set, otherwise public. This tells browsers to validate conditional requests instead of using a timed cache. #3828 - helpers.safe_join is deprecated. Use werkzeug.utils.safe_join instead. #3828 - The request context does route matching before opening the session. This could allow a session interface to change behavior based on request.endpoint. #3776 - Use Jinja’s implementation of the |tojson filter. #3881 - Add route decorators for common HTTP methods. For example, AATTapp.post(\"/login\") is a shortcut for AATTapp.route(\"/login\", methods=[\"POST\"]). #3907 - Support async views, error handlers, before and after request, and teardown functions. #3412 - Support nesting blueprints. #593, #1548, #3923 - Set the default encoding to “UTF-8” when loading .env and .flaskenv files to allow to use non-ASCII characters. #3931 - flask shell sets up tab and history completion like the default python shell if readline is installed. #3941 - helpers.total_seconds() is deprecated. Use timedelta.total_seconds() instead. #3962 - Add type hinting. #3973.
* Tue May 26 2020 Petr Gajdos - %python3_only -> %python_alternative
* Fri Apr 03 2020 Petr Cervinka - Update to 1.1.2:
* Work around an issue when running the flask command with an external debugger on Windows. :issue:`3297`
* The static route will not catch all URLs if the Flask static_folder argument ends with a slash. :issue:`3452`- Remove python38-exception-test.patch
* Mon Dec 02 2019 John Paul Adrian Glaubitz - Fix build on SLE-12 + Add python to BuildRequires for suse_version < 1500
* Fri Nov 08 2019 Steve Kowalik - Add python38-exception-test.patch to fix test failures under Python 3.8
* Fri Jul 19 2019 Tomáš Chvátal - Update to 1.1.1:
* The flask.json_available flag was added back for compatibility with some extensions. It will raise a deprecation warning when used, and will be removed in version 2.0.0. #3288
* Sat Jul 06 2019 Arun Persaud - specfile:
* updated version of Werkzeug requirement to 0.15
* AUTHORS file not in tar-ball
* license file got renamed to LICENSE.rst
* be more specific in %files section- update to version 1.1.0:
* Bump minimum Werkzeug version to >= 0.15.
* Drop support for Python 3.4.
* Error handlers for \"InternalServerError\" or \"500\" will always be passed an instance of \"InternalServerError\". If they are invoked due to an unhandled exception, that original exception is now available as \"e.original_exception\" rather than being passed directly to the handler. The same is true if the handler is for the base \"HTTPException\". This makes error handler behavior more consistent. :pr:`3266` + :meth:`Flask.finalize_request` is called for all unhandled exceptions even if there is no \"500\" error handler.
* :attr:`Flask.logger` takes the same name as :attr:`Flask.name` (the value passed as \"Flask(import_name)\". This reverts 1.0\'s behavior of always logging to \"\"flask.app\"\", in order to support multiple apps in the same process. A warning will be shown if old configuration is detected that needs to be moved. :issue:`2866`
* :meth:`flask.RequestContext.copy` includes the current session object in the request context copy. This prevents \"session\" pointing to an out-of-date object. :issue:`2935`
* Using built-in RequestContext, unprintable Unicode characters in Host header will result in a HTTP 400 response and not HTTP 500 as previously. :pr:`2994`
* :func:`send_file` supports :class:`~os.PathLike` objects as described in PEP 0519, to support :mod:`pathlib` in Python 3. :pr:`3059`
* :func:`send_file` supports :class:`~io.BytesIO` partial content. :issue:`2957`
* :func:`open_resource` accepts the \"rt\" file mode. This still does the same thing as \"r\". :issue:`3163`
* The :attr:`MethodView.methods` attribute set in a base class is used by subclasses. :issue:`3138`
* :attr:`Flask.jinja_options` is a \"dict\" instead of an \"ImmutableDict\" to allow easier configuration. Changes must still be made before creating the environment. :pr:`3190`
* Flask\'s \"JSONMixin\" for the request and response wrappers was moved into Werkzeug. Use Werkzeug\'s version with Flask-specific support. This bumps the Werkzeug dependency to >= 0.15. :issue:`3125`
* The \"flask\" command entry point is simplified to take advantage of Werkzeug 0.15\'s better reloader support. This bumps the Werkzeug dependency to >= 0.15. :issue:`3022`
* Support \"static_url_path\" that ends with a forward slash. :issue:`3134`
* Support empty \"static_folder\" without requiring setting an empty \"static_url_path\" as well. :pr:`3124`
* :meth:`jsonify` supports :class:`dataclasses.dataclass` objects. :pr:`3195`
* Allow customizing the :attr:`Flask.url_map_class` used for routing. :pr:`3069`
* The development server port can be set to 0, which tells the OS to pick an available port. :issue:`2926`
* The return value from :meth:`cli.load_dotenv` is more consistent with the documentation. It will return \"False\" if python-dotenv is not installed, or if the given path isn\'t a file. :issue:`2937`
* Signaling support has a stub for the \"connect_via\" method when the Blinker library is not installed. :pr:`3208`
* Add an \"--extra-files\" option to the \"flask run\" CLI command to specify extra files that will trigger the reloader on change. :issue:`2897`
* Allow returning a dictionary from a view function. Similar to how returning a string will produce a \"text/html\" response, returning a dict will call \"jsonify\" to produce a \"application/json\" response. :pr:`3111`
* Blueprints have a \"cli\" Click group like \"app.cli\". CLI commands registered with a blueprint will be available as a group under the \"flask\" command. :issue:`1357`.
* When using the test client as a context manager (\"with client:\"), all preserved request contexts are popped when the block exits, ensuring nested contexts are cleaned up correctly. :pr:`3157`
* Show a better error message when the view return type is not supported. :issue:`3214`
* \"flask.testing.make_test_environ_builder()\" has been deprecated in favour of a new class \"flask.testing.EnvironBuilder\". :pr:`3232`
* The \"flask run\" command no longer fails if Python is not built with SSL support. Using the \"--cert\" option will show an appropriate error message. :issue:`3211`
* URL matching now occurs after the request context is pushed, rather than when it\'s created. This allows custom URL converters to access the app and request contexts, such as to query a database for an id. :issue:`3088`- changes from version 1.0.4:
* The key information for \"BadRequestKeyError\" is no longer cleared outside debug mode, so error handlers can still access it. This requires upgrading to Werkzeug 0.15.5. :issue:`3249`
* \"send_file\" url quotes the \":\" and \"/\" characters for more compatible UTF-8 filename support in some browsers. :issue:`3074`
* Fixes for PEP451 import loaders and pytest 5.x. :issue:`3275`
* Show message about dotenv on stderr instead of stdout. :issue:`3285`
* Tue May 28 2019 Tomáš Chvátal - Update to 1.0.3:
* :func:`send_file` encodes filenames as ASCII instead of Latin-1 (ISO-8859-1). This fixes compatibility with Gunicorn, which is stricter about header encodings than PEP 3333. (`#2766`_)
* Allow custom CLIs using ``FlaskGroup`` to set the debug flag without it always being overwritten based on environment variables. (`#2765`_)
* ``flask --version`` outputs Werkzeug\'s version and simplifies the Python version. (`#2825`_)
* :func:`send_file` handles an ``attachment_filename`` that is a native Python 2 string (bytes) with UTF-8 coded bytes. (`#2933`_)
* A catch-all error handler registered for ``HTTPException`` will not handle ``RoutingExcpetion``, which is used internally during routing. This fixes the unexpected behavior that had been introduced in 1.0. (`#2986`_)
* Passing the ``json`` argument to ``app.test_client`` does not push/pop an extra app context. (`#2900`_)
* Sun May 06 2018 arunAATTgmx.de- update to version 1.0.2:
* Fix more backwards compatibility issues with merging slashes between a blueprint prefix and route. (`#2748`_)
* Fix error with \"flask routes\" command when there are no routes. (`#2751`_)- changes from version 1.0.1:
* Fix registering partials (with no \"__name__\") as view functions. (`#2730`_)
* Don\'t treat lists returned from view functions the same as tuples. Only tuples are interpreted as response data. (`#2736`_)
* Extra slashes between a blueprint\'s \"url_prefix\" and a route URL are merged. This fixes some backwards compatibility issues with the change in 1.0. (`#2731`_, `#2742`_)
* Only trap \"BadRequestKeyError\" errors in debug mode, not all \"BadRequest\" errors. This allows \"abort(400)\" to continue working as expected. (`#2735`_)
* The \"FLASK_SKIP_DOTENV\" environment variable can be set to \"1\" to skip automatically loading dotenv files. (`#2722`_)
* Sat Apr 28 2018 arunAATTgmx.de- specfile:
* update copyright year
* updated version of dependencies
* removed patch: flask-python36.patch included upstream
* CHANGES->CHANGES.rst
* README->README.rst- update to version 1.0:
*
*
*Python 2.6 and 3.3 are no longer supported.
*
* (`pallets/meta#24`_)
* Bump minimum dependency versions to the latest stable versions: Werkzeug >= 0.14, Jinja >= 2.10, itsdangerous >= 0.24, Click >= 5.1. (`#2586`_)
* Skip :meth:`app.run ` when a Flask application is run from the command line. This avoids some behavior that was confusing to debug.
* Change the default for :data:`JSONIFY_PRETTYPRINT_REGULAR` to \"False\". :func:`~json.jsonify` returns a compact format by default, and an indented format in debug mode. (`#2193`_)
* :meth:`Flask.__init__ ` accepts the \"host_matching\" argument and sets it on :attr:`~Flask.url_map`. (`#1559`_)
* :meth:`Flask.__init__ ` accepts the \"static_host\" argument and passes it as the \"host\" argument when defining the static route. (`#1559`_)
* :func:`send_file` supports Unicode in \"attachment_filename\". (`#2223`_)
* Pass \"_scheme\" argument from :func:`url_for` to :meth:`~Flask.handle_url_build_error`. (`#2017`_)
* :meth:`~Flask.add_url_rule` accepts the \"provide_automatic_options\" argument to disable adding the \"OPTIONS\" method. (`#1489`_)
* :class:`~views.MethodView` subclasses inherit method handlers from base classes. (`#1936`_)
* Errors caused while opening the session at the beginning of the request are handled by the app\'s error handlers. (`#2254`_)
* Blueprints gained :attr:`~Blueprint.json_encoder` and :attr:`~Blueprint.json_decoder` attributes to override the app\'s encoder and decoder. (`#1898`_)
* :meth:`Flask.make_response` raises \"TypeError\" instead of \"ValueError\" for bad response types. The error messages have been improved to describe why the type is invalid. (`#2256`_)
* Add \"routes\" CLI command to output routes registered on the application. (`#2259`_)
* Show warning when session cookie domain is a bare hostname or an IP address, as these may not behave properly in some browsers, such as Chrome. (`#2282`_)
* Allow IP address as exact session cookie domain. (`#2282`_)
* \"SESSION_COOKIE_DOMAIN\" is set if it is detected through \"SERVER_NAME\". (`#2282`_)
* Auto-detect zero-argument app factory called \"create_app\" or \"make_app\" from \"FLASK_APP\". (`#2297`_)
* Factory functions are not required to take a \"script_info\" parameter to work with the \"flask\" command. If they take a single parameter or a parameter named \"script_info\", the :class:`~cli.ScriptInfo` object will be passed. (`#2319`_)
* \"FLASK_APP\" can be set to an app factory, with arguments if needed, for example \"FLASK_APP=myproject.app:create_app(\'dev\')\". (`#2326`_)
* \"FLASK_APP\" can point to local packages that are not installed in editable mode, although \"pip install -e\" is still preferred. (`#2414`_)
* The :class:`~views.View` class attribute :attr:`~views.View.provide_automatic_options` is set in :meth:`~views.View.as_view`, to be detected by :meth:`~Flask.add_url_rule`. (`#2316`_)
* Error handling will try handlers registered for \"blueprint, code\", \"app, code\", \"blueprint, exception\", \"app, exception\". (`#2314`_)
* \"Cookie\" is added to the response\'s \"Vary\" header if the session is accessed at all during the request (and not deleted). (`#2288`_)
* :meth:`~Flask.test_request_context` accepts \"subdomain\" and \"url_scheme\" arguments for use when building the base URL. (`#1621`_)
* Set :data:`APPLICATION_ROOT` to \"\'/\'\" by default. This was already the implicit default when it was set to \"None\".
* :data:`TRAP_BAD_REQUEST_ERRORS` is enabled by default in debug mode. \"BadRequestKeyError\" has a message with the bad key in debug mode instead of the generic bad request message. (`#2348`_)
* Allow registering new tags with :class:`~json.tag.TaggedJSONSerializer` to support storing other types in the session cookie. (`#2352`_)
* Only open the session if the request has not been pushed onto the context stack yet. This allows :func:`~stream_with_context` generators to access the same session that the containing view uses. (`#2354`_)
* Add \"json\" keyword argument for the test client request methods. This will dump the given object as JSON and set the appropriate content type. (`#2358`_)
* Extract JSON handling to a mixin applied to both the :class:`Request` and :class:`Response` classes. This adds the :meth:`~Response.is_json` and :meth:`~Response.get_json` methods to the response to make testing JSON response much easier. (`#2358`_)
* Removed error handler caching because it caused unexpected results for some exception inheritance hierarchies. Register handlers explicitly for each exception if you want to avoid traversing the MRO. (`#2362`_)
* Fix incorrect JSON encoding of aware, non-UTC datetimes. (`#2374`_)
* Template auto reloading will honor debug mode even even if :attr:`~Flask.jinja_env` was already accessed. (`#2373`_)
* The following old deprecated code was removed. (`#2385`_) + \"flask.ext\" - import extensions directly by their name instead of through the \"flask.ext\" namespace. For example, \"import flask.ext.sqlalchemy\" becomes \"import flask_sqlalchemy\". + \"Flask.init_jinja_globals\" - extend :meth:`Flask.create_jinja_environment` instead. + \"Flask.error_handlers\" - tracked by :attr:`Flask.error_handler_spec`, use :meth:`Flask.errorhandler` to register handlers. + \"Flask.request_globals_class\" - use :attr:`Flask.app_ctx_globals_class` instead. + \"Flask.static_path\" - use :attr:`Flask.static_url_path` instead. + \"Request.module\" - use :attr:`Request.blueprint` instead.
* The :attr:`Request.json` property is no longer deprecated. (`#1421`_)
* Support passing a :class:`~werkzeug.test.EnvironBuilder` or \"dict\" to :meth:`test_client.open `. (`#2412`_)
* The \"flask\" command and :meth:`Flask.run` will load environment variables from \".env\" and \".flaskenv\" files if python-dotenv is installed. (`#2416`_)
* When passing a full URL to the test client, the scheme in the URL is used instead of :data:`PREFERRED_URL_SCHEME`. (`#2430`_)
* :attr:`Flask.logger` has been simplified. \"LOGGER_NAME\" and \"LOGGER_HANDLER_POLICY\" config was removed. The logger is always named \"flask.app\". The level is only set on first access, it doesn\'t check :attr:`Flask.debug` each time. Only one format is used, not different ones depending on :attr:`Flask.debug`. No handlers are removed, and a handler is only added if no handlers are already configured. (`#2436`_)
* Blueprint view function names may not contain dots. (`#2450`_)
* Fix a \"ValueError\" caused by invalid \"Range\" requests in some cases. (`#2526`_)
* The development server uses threads by default. (`#2529`_)
* Loading config files with \"silent=True\" will ignore :data:`~errno.ENOTDIR` errors. (`#2581`_)
* Pass \"--cert\" and \"--key\" options to \"flask run\" to run the development server over HTTPS. (`#2606`_)
* Added :data:`SESSION_COOKIE_SAMESITE` to control the \"SameSite\" attribute on the session cookie. (`#2607`_)
* Added :meth:`~flask.Flask.test_cli_runner` to create a Click runner that can invoke Flask CLI commands for testing. (`#2636`_)
* Subdomain matching is disabled by default and setting :data:`SERVER_NAME` does not implicily enable it. It can be enabled by passing \"subdomain_matching=True\" to the \"Flask\" constructor. (`#2635`_)
* A single trailing slash is stripped from the blueprint \"url_prefix\" when it is registered with the app. (`#2629`_)
* :meth:`Request.get_json` doesn\'t cache the result if parsing fails when \"silent\" is true. (`#2651`_)
* :func:`Request.get_json` no longer accepts arbitrary encodings. Incoming JSON should be encoded using UTF-8 per :rfc:`8259`, but Flask will autodetect UTF-8, -16, or -32. (`#2691`_)
* Added :data:`MAX_COOKIE_SIZE` and :attr:`Response.max_cookie_size` to control when Werkzeug warns about large cookies that browsers may ignore. (`#2693`_)
* Updated documentation theme to make docs look better in small windows. (`#2709`_)
* Rewrote the tutorial docs and example project to take a more structured approach to help new users avoid common pitfalls. (`#2676`_)- changes from version 0.12.3:
* :func:`Request.get_json` no longer accepts arbitrary encodings. Incoming JSON should be encoded using UTF-8 per :rfc:`8259`, but Flask will autodetect UTF-8, -16, or -32. (`#2692`_)
* Fix a Python warning about imports when using \"python -m flask\". (`#2666`_)
* Fix a \"ValueError\" caused by invalid \"Range\" requests in some cases.
