Change Logs

* Sun May 06 2018 arun@gmx.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 arun@gmx.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 <Flask.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__ <Flask>` accepts the "host_matching"
    argument and sets it on :attr:`~Flask.url_map`. (`#1559`_)
  * :meth:`Flask.__init__ <Flask>` 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 <werkzeug.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.
Version: 0.10.1-3.1
* Thu Oct 24 2013 speilicke@suse.com
- Require python-setuptools instead of distribute (upstreams merged)
* Mon Sep 09 2013 dmueller@suse.com
- add dependency on itsdangerous
* Tue Jun 25 2013 dmueller@suse.com
- update to 0.10.1
  - Fixed an issue where ``|tojson`` was not quoting single quotes which
  made the filter not work properly in HTML attributes.  Now it's
  possible to use that filter in single quoted attributes.  This should
  make using that filter with angular.js easier.
  - Added support for byte strings back to the session system.  This broke
  compatibility with the common case of people putting binary data for
  token verification into the session.
  - Fixed an issue were registering the same method twice for the same endpoint
  would trigger an exception incorrectly.
  :ref:`upgrading-to-010` for more information.
  - Added ``template_test`` methods in addition to the already existing
  ``template_filter`` method family.
  - Added ``template_global`` methods in addition to the already existing
  ``template_filter`` method family.
  - Set the content-length header for x-sendfile.
  - ``tojson`` filter now does not escape script blocks in HTML5 parsers.
  - ``tojson`` used in templates is now safe by default due.  This was
  allowed due to the different escaping behavior.
  - Flask will now raise an error if you attempt to register a new function
  on an already used endpoint.
  - Added wrapper module around simplejson and added default serialization
  of datetime objects.  This allows much easier customization of how
  JSON is handled by Flask or any Flask extension.
  - Removed deprecated internal ``flask.session`` module alias.  Use
  ``flask.sessions`` instead to get the session module.  This is not to
  be confused with ``flask.session`` the session proxy.
  - Templates can now be rendered without request context.  The behavior is
  slightly different as the ``request``, ``session`` and ``g`` objects
  will not be available and blueprint's context processors are not
  called.
  - The config object is now available to the template as a real global and
  not through a context processor which makes it available even in imported
  templates by default.
  - Added an option to generate non-ascii encoded JSON which should result
  in less bytes being transmitted over the network.  It's disabled by
  default to not cause confusion with existing libraries that might expect
  ``flask.json.dumps`` to return bytestrings by default.
  - ``flask.g`` is now stored on the app context instead of the request
  context.
  - ``flask.g`` now gained a ``get()`` method for not erroring out on non
  existing items.
  - ``flask.g`` now can be used with the ``in`` operator to see what's defined
  and it now is iterable and will yield all attributes stored.
  - ``flask.Flask.request_globals_class`` got renamed to
  ``flask.Flask.app_ctx_globals_class`` which is a better name to what it
  does since 0.10.
  - `request`, `session` and `g` are now also added as proxies to the template
  context which makes them available in imported templates.  One has to be
  very careful with those though because usage outside of macros might
  cause caching.
  - Flask will no longer invoke the wrong error handlers if a proxy
  exception is passed through.
  - Added a workaround for chrome's cookies in localhost not working
  as intended with domain names.
  - Changed logic for picking defaults for cookie values from sessions
  to work better with Google Chrome.
  - Added `message_flashed` signal that simplifies flashing testing.
  - Added support for copying of request contexts for better working with
  greenlets.
  - Removed custom JSON HTTP exception subclasses.  If you were relying on them
  you can reintroduce them again yourself trivially.  Using them however is
  strongly discouraged as the interface was flawed.
  - Python requirements changed: requiring Python 2.6 or 2.7 now to prepare
  for Python 3.3 port.
  - Changed how the teardown system is informed about exceptions.  This is now
  more reliable in case something handles an exception halfway through
  the error handling process.
  - Request context preservation in debug mode now keeps the exception
  information around which means that teardown handlers are able to
  distinguish error from success cases.
  - Added the ``JSONIFY_PRETTYPRINT_REGULAR`` configuration variable.
  - Flask now orders JSON keys by default to not trash HTTP caches due to
  different hash seeds between different workers.
  - Added `appcontext_pushed` and `appcontext_popped` signals.
  - The builtin run method now takes the ``SERVER_NAME`` into account when
  picking the default port to run on.
  - Added `flask.request.get_json()` as a replacement for the old
  `flask.request.json` property.
* Fri Nov 16 2012 saschpe@suse.de
- Disable testsuite on SLE_11_SP2
* Thu Nov 15 2012 saschpe@suse.de
- Update to version 0.9:
  + The :func:flask.Request.on_json_loading_failed now returns a JSON formatted
    response by default.
  + The :func:flask.url_for function now can generate anchors to the
    generated links.
  + The :func:flask.url_for function now can also explicitly generate
    URL rules specific to a given HTTP method.
  + Logger now only returns the debug log setting if it was not set
    explicitly.
  + Unregister a circular dependency between the WSGI environment and
    the request object when shutting down the request.  This means that
    environ werkzeug.request will be None after the response was
    returned to the WSGI server but has the advantage that the garbage
    collector is not needed on CPython to tear down the request unless
    the user created circular dependencies themselves.
  + Session is now stored after callbacks so that if the session payload
    is stored in the session you can still modify it in an after
    request callback.
  + The :class:flask.Flask class will avoid importing the provided import name
    if it can (the required first parameter), to benefit tools which build Flask
    instances programmatically.  The Flask class will fall back to using import
    on systems with custom module hooks, e.g. Google App Engine, or when the
    import name is inside a zip archive (usually a .egg) prior to Python 2.7.
  + Blueprints now have a decorator to add custom template filters application
    wide, :meth:flask.Blueprint.app_template_filter.
  + The Flask and Blueprint classes now have a non-decorator method for adding
    custom template filters application wide,
    :meth:flask.Flask.add_template_filter and
    :meth:flask.Blueprint.add_app_template_filter.
  + The :func:flask.get_flashed_messages function now allows rendering flashed
    message categories in separate blocks, through a category_filter
    argument.
  + The :meth:flask.Flask.run method now accepts None for host and port
    arguments, using default values when None.  This allows for calling run
    using configuration values, e.g. app.run(app.config.get('MYHOST'),
    app.config.get('MYPORT')), with proper behavior whether or not a config
    file is provided.
  + Please look into CHANGES for more...
* Thu Nov 10 2011 saschpe@suse.de
- Update to version 0.8:
  * Refactored session support into a session interface so that
    the implementation of the sessions can be changed without
    having to override the Flask class.
  * Empty session cookies are now deleted properly automatically.
  * View functions can now opt out of getting the automatic
    OPTIONS implementation.
  * HTTP exceptions and Bad Request errors can now be trapped so that they
    show up normally in the traceback.
  * Flask in debug mode is now detecting some common problems and tries to
    warn you about them.
  * Flask in debug mode will now complain with an assertion error if a view
    was attached after the first request was handled.  This gives earlier
    feedback when users forget to import view code ahead of time.
  * Added the ability to register callbacks that are only triggered once at
    the beginning of the first request. (:meth:Flask.before_first_request)
  * Malformed JSON data will now trigger a bad request HTTP exception instead
    of a value error which usually would result in a 500 internal server
    error if not handled.  This is a backwards incompatible change.
  * Applications now not only have a root path where the resources and modules
    are located but also an instane path which is the designated place to
    drop files that are modified at runtime (uploads etc.).  Also this is
    conceptionally only instance depending and outside version control so it's
    the perfect place to put configuration files etc.  For more information
    see :ref:instance-folders.
  * Added the APPLICATION_ROOT configuration variable.
  * Implemented :meth:~flask.testing.TestClient.session_transaction to
    easily modify sessions from the test environment.
  * Refactored test client internally.  The APPLICATION_ROOT configuration
    variable as well as SERVER_NAME are now properly used by the test client
    as defaults.
  * Added :attr:flask.views.View.decorators to support simpler decorating of
    pluggable (class based) views.
  * Fixed an issue where the test client if used with the with statement did not
    trigger the execution of the teardown handlers.
  * Added finer control over the session cookie parameters.
  * HEAD requests to a method view now automatically dispatch to the get
    method if no handler was implemented.
  * Implemented the virtual :mod:flask.ext package to import extensions from.
  * The context preservation on exceptions is now an integral component of
    Flask itself and no longer of the test client.  This cleaned up some
    internal logic and lowers the odds of runaway request contexts in unittests.

- Update to Version 0.11.1
  - Fixed a bug that prevented ``FLASK_APP=foobar/__init__.py`` from working. See
    pull request ``#1872``.
- Update to Version 0.11
  - Added support to serializing top-level arrays to :func:`flask.jsonify`. This
    introduces a security risk in ancient browsers. See
    :ref:`json-security` for details.
  - Added before_render_template signal.
  - Added `**kwargs` to :meth:`flask.Test.test_client` to support passing
    additional keyword arguments to the constructor of
    :attr:`flask.Flask.test_client_class`.
  - Added ``SESSION_REFRESH_EACH_REQUEST`` config key that controls the
    set-cookie behavior.  If set to ``True`` a permanent session will be
    refreshed each request and get their lifetime extended, if set to
    ``False`` it will only be modified if the session actually modifies.
    Non permanent sessions are not affected by this and will always
    expire if the browser window closes.
  - Made Flask support custom JSON mimetypes for incoming data.
  - Added support for returning tuples in the form ``(response, headers)``
    from a view function.
  - Added :meth:`flask.Config.from_json`.
  - Added :attr:`flask.Flask.config_class`.
  - Added :meth:`flask.config.Config.get_namespace`.
  - Templates are no longer automatically reloaded outside of debug mode. This
    can be configured with the new ``TEMPLATES_AUTO_RELOAD`` config key.
  - Added a workaround for a limitation in Python 3.3's namespace loader.
  - Added support for explicit root paths when using Python 3.3's namespace
    packages.
  - Added :command:`flask` and the ``flask.cli`` module to start the local
    debug server through the click CLI system.  This is recommended over the old
    ``flask.run()`` method as it works faster and more reliable due to a
    different design and also replaces ``Flask-Script``.
  - Error handlers that match specific classes are now checked first,
    thereby allowing catching exceptions that are subclasses of HTTP
    exceptions (in ``werkzeug.exceptions``).  This makes it possible
    for an extension author to create exceptions that will by default
    result in the HTTP error of their choosing, but may be caught with
    a custom error handler if desired.
  - Added :meth:`flask.Config.from_mapping`.
  - Flask will now log by default even if debug is disabled.  The log format is
    now hardcoded but the default log handling can be disabled through the
    ``LOGGER_HANDLER_POLICY`` configuration key.
  - Removed deprecated module functionality.
  - Added the ``EXPLAIN_TEMPLATE_LOADING`` config flag which when enabled will
    instruct Flask to explain how it locates templates.  This should help
    users debug when the wrong templates are loaded.
  - Enforce blueprint handling in the order they were registered for template
    loading.
  - Ported test suite to py.test.
  - Deprecated ``request.json`` in favour of ``request.get_json()``.
  - Add "pretty" and "compressed" separators definitions in jsonify() method.
    Reduces JSON response size when JSONIFY_PRETTYPRINT_REGULAR=False by removing
    unnecessary white space included by default after separators.
  - JSON responses are now terminated with a newline character, because it is a
    convention that UNIX text files end with a newline and some clients don't
    deal well when this newline is missing. See
    https://github.com/pallets/flask/pull/1262 -- this came up originally as a
    part of https://github.com/kennethreitz/httpbin/issues/168
  - The automatically provided ``OPTIONS`` method is now correctly disabled if
    the user registered an overriding rule with the lowercase-version
    ``options`` (issue ``#1288``).
  - ``flask.json.jsonify`` now supports the ``datetime.date`` type (pull request
    ``#1326``).
  - Don't leak exception info of already catched exceptions to context teardown
    handlers (pull request ``#1393``).
  - Allow custom Jinja environment subclasses (pull request ``#1422``).
  - ``flask.g`` now has ``pop()`` and ``setdefault`` methods.
  - Turn on autoescape for ``flask.templating.render_template_string`` by default
    (pull request ``#1515``).
  - ``flask.ext`` is now deprecated (pull request ``#1484``).
  - ``send_from_directory`` now raises BadRequest if the filename is invalid on
    the server OS (pull request ``#1763``).
  - Added the ``JSONIFY_MIMETYPE`` configuration variable (pull request ``#1728``).
  - Exceptions during teardown handling will no longer leave bad application
    contexts lingering around.
- Update to Version 0.10.2
  - Fixed broken `test_appcontext_signals()` test case.
  - Raise an :exc:`AttributeError` in :func:`flask.helpers.find_package` with a
    useful message explaining why it is raised when a PEP 302 import hook is used
    without an `is_package()` method.
  - Fixed an issue causing exceptions raised before entering a request or app
    context to be passed to teardown handlers.
  - Fixed an issue with query parameters getting removed from requests in
    the test client when absolute URLs were requested.
  - Made `@before_first_request` into a decorator as intended.
  - Fixed an etags bug when sending a file streams with a name.
  - Fixed `send_from_directory` not expanding to the application root path
    correctly.
  - Changed logic of before first request handlers to flip the flag after
    invoking.  This will allow some uses that are potentially dangerous but
    should probably be permitted.
  - Fixed Python 3 bug when a handler from `app.url_build_error_handlers`
    reraises the `BuildError`.
- Implement update-alternatives
