It is up -to the developer to choose a template engine, database adapter, and even -how to handle requests. It can be used to build all sorts of end user -applications such as blogs, wikis, or bulletin boards. - -`Flask`_ wraps Werkzeug, using it to handle the details of WSGI while -providing more structure

[![Build Status](https://travis-ci.org/B2W-BIT/aiologger.svg?branch=master)](https://travis-ci.org/B2W-BIT/aiologger) - [![codecov](https://codecov.io/gh/B2W-BIT/aiologger/branch/master/graph/badge.svg)](https://codecov.io/gh/B2W-BIT/aiologger) - - - # About the Project - - The builtin python logger is I/O blocking. This means that using the builtin - `logging` module will interfere with your asynchronouns application performance. - `aiologger` aims to be the standard Asynchronous non blocking logging for - python and asyncio. - - # A word about async, Python and files - - Tldr; `aiologger` is only fully async when logging to stdout/stderr. If you log into files on disk you are not being fully async and will be using Threads. - - `aiologger` was created when we realized that there were no async logging libs to use. At the time, Python's built-in logging infra-structure was fully sync (still is, 3.8 beta is out). That's why we created aiologger. - - Despite everything (in Linux) being a file descriptor, a Network file descriptor and the stdout/stderr FDs are treated differently from files on disk FDs. This happens because there's no stable/usable async I/O interface published by the OS to be used by Python (or any other language). That's why **logging to files is NOT truly async**. `aiologger` implementation of file logging uses [aiofiles](https://github.com/Tinche/aiofiles), which uses a Thread Pool to write the data. Keep this in mind when using `aiologger` for file logging. - - Other than that, we hope `aiologger` helps you write fully async apps. :tada: :tada: - - - # Installation - - ``` - pip install aiologger - ``` - - # Testing - - ``` - pipenv install --dev - pipenv run test - ``` - - # Implemented interfaces - - aiologger implements two different interfaces that you can use to generate your logs. - You can generate your logs using the `async/await` syntax or, if you for any reason can't (or don't want to) - change all your codebase to use this syntax you can use aiologger as if it were synchronous, but behind the scenes - your logs will be generated asynchronously. - - - # Migrating from standard lib logging - - - ## Using aiologger with the standard syntax - - If you prefer not to use the `async/await` all you need to do is to replace you logger instance with an instance of `aiologger.Logger`. - For now on you can call `logger.info()` the same way you are (probably) already calling. Here is a simple example: - - ```python - - import asyncio - import logging - - from logging import getLogger - - - async def main(): - logger = getLogger(__name__) - logging.basicConfig(level=logging.DEBUG, format="%(message)s") - - logger.debug("debug") - logger.info("info") - - logger.warning("warning") - logger.error("error") - logger.critical("critical") - - - if __name__ == "__main__": - asyncio.run(main()) - ``` - - Which will output the following lines: - - ``` - debug - info - warning - error - critical - ``` - - --- - - If you want to generate all your logs asynchronously, you just have to change the instance of the `logger` object. - To do that, all we need to change those lines from: - - ```python - from logging import getLogger - - logger = getLogger(__name__) - ``` - - to: - - ```python - from aiologger import Logger - - logger = Logger.with_default_handlers() - ``` - - and here is the complete example, generating all log lines asynchronously. - - ```python - import asyncio - from aiologger import Logger - - - async def main(): - logger = Logger.with_default_handlers(name='my-logger') - - logger.debug("debug") - logger.info("info") - - logger.warning("warning") - logger.error("error") - logger.critical("critical") - - await logger.shutdown() - - - if __name__ == "__main__": - asyncio.run(main()) - ``` - - This code will output the following lines: - - ``` - warning - debug - info - error - critical - ``` - - As you might have noticed, the output order **IS NOT GUARANTEED**. - If some kind of order is important to you, you'll need to use the `await` syntax. - But thinking about an asyncio application, where every I/O operation is asynchronous, - this shouldn't really matter. - - Also note that logger calls may only be made from an `async def` or from a - function called with an `async def` somewhere in the callstack. - - ## Using aiologger with the async/await syntax - - - ```python - import asyncio - from aiologger import Logger - - - async def main(): - logger = Logger.with_default_handlers(name='my-logger') - - await logger.debug("debug at stdout") - await logger.info("info at stdout") - - await logger.warning("warning at stderr") - await logger.error("error at stderr") - await logger.critical("critical at stderr") - - await logger.shutdown() - - if __name__ == "__main__": - asyncio.run(main()) - ``` - - The most basic use case is to log the output into `stdout` and `stderr`. - Using `Logger.with_default_handlers` you're able to effortlessly create a new - `Logger` instance with 2 distinct handlers: - * One for handling `debug` and `info` methods and writing to `stdout`; - * The other, for handling `warning`, `critical`, `exception` and `error` methods and writing to `stderr`. - - Since everything is asynchronous, this means that for the same handler, - the output order is guaranteed, but not between distinct handlers. - The above code may output the following: - - ``` - warning at stderr - debug at stdout - error at stderr - info at stdout - critical at stderr - ``` - - You may notice that the order between the same handler is guaranteed. E.g.: - * `debug at stdout` was outputted before `info at stdout` - * `warning at stderr` was outputted before `error at stderr` - * between lines of distinct handlers, the order isn't guaranteed. - `warning at stderr` was outputted before `debug at stdout` - - ## Lazy initialization - - Since the actual stream initialization only happens on the first log call, it's - possible to initialize `aiologger.Logger` instances outside a running event - loop: - - - ```python - - import asyncio - from aiologger import Logger - - - logger = Logger.with_default_handlers(name='my-logger') - - - async def main(): - - await logger.debug("debug at stdout") - await logger.info("info at stdout") - - await logger.warning("warning at stderr") - await logger.error("error at stderr") - await logger.critical("critical at stderr") - - await logger.shutdown() - - if __name__ == "__main__": - asyncio.run(main()) - ``` - - # Loggers - - ## JsonLogger - - A simple, featureful, drop-in replacement to the default `aiologger.Logger` - that grants to always log valid, single line, JSON output. - - ### It logs everything - - ```python - import asyncio - from datetime import datetime - - from aiologger.loggers.json import JsonLogger - - - async def main(): - logger = JsonLogger.with_default_handlers() - await logger.info("Im a string") - # {"logged_at": "2018-06-14T09:34:56.482817", "line_number": 9, "function": "main", "level": "INFO", "file_path": "/Users/diogo.mmartins/Library/Preferences/PyCharm2018.1/scratches/scratch_47.py", "msg": "Im a string"} - - await logger.info({ - 'date_objects': datetime.now(), - 'exceptions': KeyError("Boooom"), - 'types': JsonLogger - }) - # {"logged_at": "2018-06-14T09:34:56.483000", "line_number": 13, "function": "main", "level": "INFO", "file_path": "/Users/diogo.mmartins/Library/Preferences/PyCharm2018.1/scratches/scratch_47.py", "msg": {"date_objects": "2018-06-14T09:34:56.482953", "exceptions": "Exception: KeyError('Boooom',)", "types": ""}} - - await logger.shutdown() - - - if __name__ == "__main__": - asyncio.run(main()) - ``` - - ### JsonLogger Options - - `Callable[[], str]` log values may also be used to generate dynamic content that - are evaluated at serialization time. All you need to do is wrap the callable - using `CallableWrapper`: - - ```python - import asyncio - import logging - from random import randint - - from aiologger.loggers.json import JsonLogger - from aiologger.utils import CallableWrapper - - - def rand(): - return randint(1, 100) - - - logger = JsonLogger.with_default_handlers(level=logging.DEBUG) - - - async def main(): - - await logger.info(CallableWrapper(rand)) - # {"logged_at": "2018-06-14T09:37:52.624123", "line_number": 15, "function": "main", "level": "INFO", "file_path": "/Users/diogo.mmartins/Library/Preferences/PyCharm2018.1/scratches/scratch_47.py", "msg": 70} - - await logger.info({"Xablau": CallableWrapper(rand)}) - # {"logged_at": "2018-06-14T09:37:52.624305", "line_number": 18, "function": "main", "level": "INFO", "file_path": "/Users/diogo.mmartins/Library/Preferences/PyCharm2018.1/scratches/scratch_47.py", "msg": {"Xablau": 29}} - - await logger.shutdown() - - if __name__ == "__main__": - asyncio.run(main()) - ``` - - ### Adding content to root - - By default, everything passed to the log methods is inserted inside - the `msg` root attribute, but sometimes we want to add content to the root level. - - #### Flatten - - This behavior may be achieved using `flatten`. Which is - available both as a method parameter and instance attribute. - - As an instance attribute, every call to a log method would "flat" the dict attributes. - - ```python - import asyncio - import logging - from aiologger.loggers.json import JsonLogger - - - async def main(): - logger = JsonLogger.with_default_handlers(level=logging.DEBUG, flatten=True) - - await logger.info({"status_code": 200, "response_time": 0.00534534}) - # {"status_code": 200, "response_time": 0.534534, "logged_at": "2017-08-11T16:18:58.446985", "line_number": 6, "function": "", "level": "INFO", "path": "/Users/diogo/PycharmProjects/aiologger/bla.py"} - - await logger.error({"status_code": 404, "response_time": 0.00134534}) - # {"status_code": 200, "response_time": 0.534534, "logged_at": "2017-08-11T16:18:58.446986", "line_number": 6, "function": "", "level": "INFO", "path": "/Users/diogo/PycharmProjects/aiologger/bla.py"} - - await logger.shutdown() - - if __name__ == "__main__": - asyncio.run(main()) - ``` - - As a method parameter, only the specific call would add the content to the root. - - ```python - import asyncio - import logging - from aiologger.loggers.json import JsonLogger - - - async def main(): - logger = await JsonLogger.with_default_handlers(level=logging.DEBUG) - - await logger.info({"status_code": 200, "response_time": 0.00534534}, flatten=True) - # {"logged_at": "2017-08-11T16:23:16.312441", "line_number": 6, "function": "", "level": "INFO", "path": "/Users/diogo/PycharmProjects/aiologger/bla.py", "status_code": 200, "response_time": 0.00534534} - - await logger.error({"status_code": 404, "response_time": 0.00134534}) - # {"logged_at": "2017-08-11T16:23:16.312618", "line_number": 8, "function": "", "level": "ERROR", "path": "/Users/diogo/PycharmProjects/aiologger/bla.py", "msg": {"status_code": 404, "response_time": 0.00134534}} - - await logger.shutdown() - - if __name__ == "__main__": - asyncio.run(main()) - ``` - - **Warning**: It is possible to overwrite keys that are already present at root level. - - ```python - import asyncio - import logging - from aiologger.loggers.json import JsonLogger - - - async def main(): - logger = JsonLogger.with_default_handlers(level=logging.DEBUG) - - await logger.info({'logged_at': 'Yesterday'}, flatten=True) - # {"logged_at": "Yesterday", "line_number": 6, "function": "", "level": "INFO", "path": "/Users/diogo/PycharmProjects/aiologger/bla.py"} - - await logger.shutdown() - - if __name__ == "__main__": - asyncio.run(main()) - ``` - - #### Extra - - The `extra` parameter allow you to add specific content to root: - - - ```python - import asyncio - import logging - from aiologger.loggers.json import JsonLogger - - - async def main(): - a = 69 - b = 666 - c = [a, b] - logger = JsonLogger.with_default_handlers(level=logging.DEBUG) - - await logger.info("I'm a simple log") - # {"msg": "I'm a simple log", "logged_at": "2017-08-11T12:21:05.722216", "line_number": 5, "function": "", "level": "INFO", "path": "/Users/diogo/PycharmProjects/aiologger/bla.py"} - - await logger.info({"dog": "Xablau"}, extra=locals()) - # {"logged_at": "2018-06-14T09:47:29.477705", "line_number": 14, "function": "main", "level": "INFO", "file_path": "/Users/diogo.mmartins/Library/Preferences/PyCharm2018.1/scratches/scratch_47.py", "msg": {"dog": "Xablau"}, "logger": "", "c": [69, 666], "b": 666, "a": 69} - - await logger.shutdown() - - - if __name__ == "__main__": - asyncio.run(main()) - ``` - - It also allows you to override the default root content: - - ```python - import asyncio - import logging - from aiologger.loggers.json import JsonLogger - - - async def main(): - logger = JsonLogger.with_default_handlers(level=logging.DEBUG) - - await logger.info("I'm a simple log") - # {"msg": "I'm a simple log", "logged_at": "2017-08-11T12:21:05.722216", "line_number": 6, "function": "", "level": "INFO", "path": "/Users/diogo/PycharmProjects/aiologger/bla.py"} - - await logger.info("I'm a simple log", extra={'logged_at': 'Yesterday'}) - # {"msg": "I'm a simple log", "logged_at": "Yesterday", "line_number": 6, "function": "", "level": "INFO", "path": "/Users/diogo/PycharmProjects/aiologger/bla.py"} - - await logger.shutdown() - - if __name__ == "__main__": - asyncio.run(main()) - ``` - - and it may also be used as an instance attribute: - - ```python - import asyncio - import logging - from aiologger.loggers.json import JsonLogger - - - async def main(): - logger = JsonLogger.with_default_handlers(level=logging.DEBUG, extra={'logged_at': 'Yesterday'}) - - await logger.info("I'm a simple log") - # {"msg": "I'm a simple log", "logged_at": "Yesterday", "line_number": 6, "function": "", "level": "INFO", "path": "/Users/diogo/PycharmProjects/aiologger/bla.py"} - - await logger.info("I'm a simple log") - # {"msg": "I'm a simple log", "logged_at": "Yesterday", "line_number": 6, "function": "", "level": "INFO", "path": "/Users/diogo/PycharmProjects/aiologger/bla.py"} - - await logger.shutdown() - - if __name__ == "__main__": - asyncio.run(main()) - ``` - - - #### Exclude default logger fields - - If you think that the default fields are too much, it's also possible to - exclude fields from the output message. - - ```python - import asyncio - import logging - from aiologger.loggers.json import JsonLogger - from aiologger.formatters.json import FUNCTION_NAME_FIELDNAME, LOGGED_AT_FIELDNAME - - - async def main(): - logger = JsonLogger.with_default_handlers( - level=logging.DEBUG, - exclude_fields=[FUNCTION_NAME_FIELDNAME, - LOGGED_AT_FIELDNAME, - 'file_path', - 'line_number'] - ) - - await logger.info("Function, file path and line number wont be printed") - # {"level": "INFO", "msg": "Function, file path and line number wont be printed"} - - await logger.shutdown() - - if __name__ == "__main__": - asyncio.run(main()) - ``` - - ### Serializer options - - `serializer_kwargs` is available both as instance attribute and as - a log method parameter and may be used to pass keyword arguments to the - `serializer` function. (See more: https://docs.python.org/3/library/json.html) - - For pretty printing the output, you may use the `indent` kwarg. Ex.: - - ```python - import asyncio - import logging - from aiologger.loggers.json import JsonLogger - - - async def main(): - logger = JsonLogger.with_default_handlers( - level=logging.DEBUG, - serializer_kwargs={'indent': 4} - ) - - await logger.info({ - "artist": "Black Country Communion", - "song": "Cold" - }) - - await logger.shutdown() - - if __name__ == "__main__": - asyncio.run(main()) - ``` - - Would result in a pretty indented output: - - ```javascript - { - "logged_at": "2017-08-11T21:04:21.559070", - "line_number": 5, - "function": "", - "level": "INFO", - "file_path": "/Users/diogo/Library/Preferences/PyCharm2017.1/scratches/scratch_32.py", - "msg": { - "artist": "Black Country Communion", - "song": "Cold" - } - } - ``` - - The same result can be achieved making a log call with `serializer_kwargs` - as a parameter. - - - ```python - await logger.warning({'artist': 'Black Country Communion', 'song': 'Cold'}, serializer_kwargs={'indent': 4}) - ``` - - # Handlers - - ## AsyncStreamHandler - - A handler class for writing logs into a stream which may be `sys.stdout` - or `sys.stderr`. If a stream isn't provided, it defaults to `sys.stderr`. If - `level` is not specified, `logging.NOTSET` is used. If `formatter` is not - `None`, it is used to format the log record before `emit()` gets called. A - `filter` may be used to filter log records - - - ```python - import sys - from aiologger.handlers.streams import AsyncStreamHandler - - - handler = AsyncStreamHandler(stream=sys.stdout) - ``` - It also accepts a level, formatter and filter at the initialization. - - ## AsyncFileHandler - - **Important**: AsyncFileHandler depends on a optional dependency and you should - install aiologger with `pip install aiologger[aiofiles]` - - A handler class that sends logs into files. The specified file is opened - and used as the _stream_ for logging. If `mode` is not specified, 'a' is - used. If `encoding` is not `None`, it is used to open the file with that - encoding. The file opening is delayed until the first call to `emit()`. - - ```python - from aiologger.handlers.files import AsyncFileHandler - from tempfile import NamedTemporaryFile - - - temp_file = NamedTemporaryFile() - handler = AsyncFileHandler(filename=temp_file.name) - ``` - # Options - - * `AIOLOGGER_HANDLE_ERROR_FALLBACK_ENABLED` - An environment variable that tells - aiologger whether it should emit a log to `stderr` in case of a handler emit - raises an exceptions. To disable the default behaviour, set this - environment variable to a falsy value `("False", "false", "0")`. Default: `True` - - # Compatibility - - The explicit passing of a `loop` keyword argument, and subsequent access of a - `.loop` attribute, has been deprecated and will be removed in version 0.7.0 for - Loggers and Handlers. - - Currently tested only on python 3.6 and 3.7 - - # Depencencies - - Has none. - -Keywords: logging json log output -Platform: UNKNOWN -Classifier: Development Status :: 4 - Beta -Classifier: Framework :: AsyncIO -Classifier: Intended Audience :: Developers -Classifier: License :: OSI Approved :: MIT License -Classifier: Intended Audience :: System Administrators -Classifier: Intended Audience :: Information Technology -Classifier: Natural Language :: English -Classifier: Operating System :: MacOS :: MacOS X -Classifier: Operating System :: Unix -Classifier: Programming Language :: Python :: 3.6 -Classifier: Programming Language :: Python :: 3.7 -Classifier: Topic :: System :: Logging -Classifier: Topic :: Software Development :: Libraries -Requires-Python: >=3.6 -Description-Content-Type: text/markdown -Provides-Extra: aiofiles diff --git a/python3-vckonline/lib/python3.8/site-packages/aiologger-0.6.0-py3.8.egg-info/SOURCES.txt b/python3-vckonline/lib/python3.8/site-packages/aiologger-0.6.0-py3.8.egg-info/SOURCES.txt deleted file mode 100644 index 569d77c..0000000 --- a/python3-vckonline/lib/python3.8/site-packages/aiologger-0.6.0-py3.8.egg-info/SOURCES.txt +++ /dev/null @@ -1,25 +0,0 @@ -README.md -setup.cfg -setup.py -aiologger/__init__.py -aiologger/filters.py -aiologger/levels.py -aiologger/logger.py -aiologger/protocols.py -aiologger/records.py -aiologger/settings.py -aiologger/utils.py -aiologger.egg-info/PKG-INFO -aiologger.egg-info/SOURCES.txt -aiologger.egg-info/dependency_links.txt -aiologger.egg-info/requires.txt -aiologger.egg-info/top_level.txt -aiologger/formatters/__init__.py -aiologger/formatters/base.py -aiologger/formatters/json.py -aiologger/handlers/__init__.py -aiologger/handlers/base.py -aiologger/handlers/files.py -aiologger/handlers/streams.py -aiologger/loggers/__init__.py -aiologger/loggers/json.py \ No newline at end of file diff --git a/python3-vckonline/lib/python3.8/site-packages/aiologger-0.6.0-py3.8.egg-info/dependency_links.txt b/python3-vckonline/lib/python3.8/site-packages/aiologger-0.6.0-py3.8.egg-info/dependency_links.txt deleted file mode 100644 index 8b13789..0000000 --- a/python3-vckonline/lib/python3.8/site-packages/aiologger-0.6.0-py3.8.egg-info/dependency_links.txt +++ /dev/null @@ -1 +0,0 @@ -

The application will work even with `__name__`, thanks - to how resources are looked up. However it will make debugging more - painful. Certain extensions can make assumptions based on the - import name of your application. For example the Flask-SQLAlchemy - extension will look for the code in your application that triggered - an SQL query in debug mode.

-    werkzeug.exceptions
-    ~~~~~~~~~~~~~~~~~~~
-
-    This module implements a number of Python exceptions you can raise from
-    within your views to trigger a standard non-200 response.
-
-
-    Usage Example
-    -------------
-
-    ::
-
-        from werkzeug.wrappers import BaseRequest
-        from werkzeug.wsgi import responder
-        from werkzeug.exceptions import HTTPException, NotFound
-
-        def view(request):
-            raise NotFound()
-
-        @responder
-        def application(environ, start_response):
-            request = BaseRequest(environ)
-            try:
-                return view(request)
-            except HTTPException as e:
-                return e
-
-
-    As you can see from this example those exceptions are callable WSGI
-    applications.  Because of Python 2.4 compatibility those do not extend
-    from the response objects but only from the python exception class.
-
-    As a matter of fact they are not Werkzeug response objects.  However you
-    can get a response object by calling ``get_response()`` on a HTTP
-    exception.
-
-    Keep in mind that you have to pass an environment to ``get_response()``
-    because some errors fetch additional information from the WSGI
-    environment.
-
-    If you want to hook in a different exception page to say, a 404 status
-    code, you can add a second except for a specific subclass of an error::
-
-        @responder
-        def application(environ, start_response):
-            request = BaseRequest(environ)
-            try:
-                return view(request)
-            except NotFound, e:
-                return not_found(request)
-            except HTTPException, e:
-                return e

-    ~~~~~~~~~~~~~
-
-    Werkzeug comes with a bunch of utilities that help Werkzeug to deal with
-    HTTP data.  Most of the classes and functions provided by this module are
-    used by the wrappers, but they are useful on their own, too, especially if
-    the response and request objects are not used.
-
-    This covers some of the more HTTP centric features of WSGI, some other
-    utilities such as cookie handling are documented in the `werkzeug.utils`
-    module.

-Application Dispatcher
-======================
-
-This middleware creates a single WSGI application that dispatches to
-multiple other WSGI applications mounted at different URL paths.
-
-A common example is writing a Single Page Application, where you have a
-backend API and a frontend written in JavaScript that does the routing
-in the browser rather than requesting different pages from the server.
-The frontend is a single HTML and JS file that should be served for any
-path besides "/api".
-
-This example dispatches to an API app under "/api", an admin app
-under "/admin", and an app that serves frontend files for all other
-requests::
-
-    app = DispatcherMiddleware(serve_frontend, {
-        '/api': api_app,
-        '/admin': admin_app,
-    })
-
-In production, you might instead handle this at the HTTP server level,
-serving files or proxying to application servers based on location. The
-API and admin apps would each be deployed with a separate WSGI server,
-and the static files would be served directly by the HTTP server.

-    websocket requests, cannot be proxied at this layer. This should
-    only be used for development, in production a real proxying server
-    should be used.
-
-    The middleware takes a dict that maps a path prefix to a dict
-    describing the host to be proxied to::
-
-        app = ProxyMiddleware(app, {
-            "/static/": {
-                "target": "http://127.0.0.1:5001/",
-            }
-        })
-
-    Each host has the following options:
-
-    ``target``:
-        The target URL to dispatch to. This is required.
-    ``remove_prefix``:
-        Whether to remove the prefix from the URL before dispatching it
-        to the target. The default is ``False``.
-    ``host``:
-        ``""`` (default):
-            The host header is automatically rewritten to the URL of the
-            target.
-        ``None``:
-            The host header is unmodified from the client request.
-        Any other value:
-            The host header is overwritten with the value.
-    ``headers``:
-        A dictionary of headers to be sent with the request to the
-        target. The default is ``{}``.
-    ``ssl_context``:
-        A :class:`ssl.SSLContext` defining how to verify requests if the
-        target is HTTPS. The default is ``None``.
-
-    In the example above, everything under ``"/static/"`` is proxied to
-    the server on port 5001. The host header is rewritten to the target,
-    and the ``"/static/"`` prefix is removed from the URLs.
-
-    :param app: The WSGI application to wrap.
-    :param targets: Proxy target configurations. See description above.
-    :param chunk_size: Size of chunks to read from input stream and
-        write to target.
-    :param timeout: Seconds before an operation to a target fails.

-X-Forwarded-For Proxy Fix
-=========================
-
-This module provides a middleware that adjusts the WSGI environ based on
-``X-Forwarded-`` headers that proxies in front of an application may
-set.
-
-When an application is running behind a proxy server, WSGI may see the
-request as coming from that server rather than the real client. Proxies
-set various headers to track where the request actually came from.
-
-This middleware should only be applied if the application is actually
-behind such a proxy, and should be configured with the number of proxies
-that are chained in front of it. Not all proxies set all the headers.
-Since incoming headers can be faked, you must set how many proxies are
-setting each header so the middleware knows what to trust.

-class SharedDataMiddleware(object):
-
-    """A WSGI middleware that provides static content for development
-    environments or simple server setups. Usage is quite simple::
-
-        import os
-        from werkzeug.middleware.shared_data import SharedDataMiddleware
-
-        app = SharedDataMiddleware(app, {
-            '/static': os.path.join(os.path.dirname(__file__), 'static')
-        })
-
-    The contents of the folder ``./shared`` will now be available on
-    ``http://example.com/shared/``.  This is pretty useful during development
-    because a standalone media server is not required.  One can also mount
-    files on the root folder and still continue to use the application because
-    the shared data middleware forwards all unhandled requests to the
-    application, even if the requests are below one of the shared folders.
-
-    If `pkg_resources` is available you can also tell the middleware to serve
-    files from package data::
-
-        app = SharedDataMiddleware(app, {
-            '/static': ('myapplication', 'static')
-        })
-
-    This will then serve the ``static`` folder in the `myapplication`
-    Python package.
-
-    The optional `disallow` parameter can be a list of :func:`~fnmatch.fnmatch`
-    rules for files that are not accessible from the web.  If `cache` is set to
-    `False` no caching headers are sent.
-
-    Currently the middleware does not support non ASCII filenames.  If the
-    encoding on the file system happens to be the encoding of the URI it may
-    work but this could also be by accident.  We strongly suggest using ASCII
-    only file names for static files.
-
-    The middleware will guess the mimetype using the Python `mimetype`
-    module.  If it's unable to figure out the charset it will fall back
-    to `fallback_mimetype`.
-
-    :param app: the application to wrap.  If you don't want to wrap an
-                application you can pass it :exc:`NotFound`.
-    :param exports: a list or dict of exported files and folders.
-    :param disallow: a list of :func:`~fnmatch.fnmatch` rules.
-    :param cache: enable or disable caching headers.
-    :param cache_timeout: the cache timeout in seconds for the headers.
-    :param fallback_mimetype: The fallback mimetype for unknown files.
-
-    .. versionchanged:: 1.0
-        The default ``fallback_mimetype`` is
-        ``application/octet-stream``. If a filename looks like a text
-        mimetype, the ``utf-8`` charset is added to it.
-
-    .. versionadded:: 0.6
-        Added ``fallback_mimetype``.
-
-    .. versionchanged:: 0.5
-        Added ``cache_timeout``.

-    werkzeug.posixemulation
-    ~~~~~~~~~~~~~~~~~~~~~~~
-
-    Provides a POSIX emulation for some features that are relevant to
-    web applications.  The main purpose is to simplify support for
-    systems such as Windows NT that are not 100% POSIX compatible.
-
-    Currently this only implements a :func:`rename` function that
-    follows POSIX semantics.  Eg: if the target file already exists it
-    will be replaced without asking.
-
-    This module was introduced in 0.6.1 and is not a public interface.
-    It might become one in later versions of Werkzeug.

-    werkzeug.routing
-    ~~~~~~~~~~~~~~~~
-
-    When it comes to combining multiple controller or view functions (however
-    you want to call them) you need a dispatcher.  A simple way would be
-    applying regular expression tests on the ``PATH_INFO`` and calling
-    registered callback functions that return the value then.
-
-    This module implements a much more powerful system than simple regular
-    expression matching because it can also convert values in the URLs and
-    build URLs.
-
-    Here a simple example that creates an URL map for an application with
-    two subdomains (www and kb) and some URL rules:
-
-    >>> m = Map([
-    ...     # Static URLs
-    ...     Rule('/', endpoint='static/index'),
-    ...     Rule('/about', endpoint='static/about'),
-    ...     Rule('/help', endpoint='static/help'),
-    ...     # Knowledge Base
-    ...     Subdomain('kb', [
-    ...         Rule('/', endpoint='kb/index'),
-    ...         Rule('/browse/', endpoint='kb/browse'),
-    ...         Rule('/browse//', endpoint='kb/browse'),
-    ...         Rule('/browse//', endpoint='kb/browse')
-    ...     ])
-    ... ], default_subdomain='www')
-
-    If the application doesn't use subdomains it's perfectly fine to not set
-    the default subdomain and not use the `Subdomain` rule factory.  The endpoint
-    in the rules can be anything, for example import paths or unique
-    identifiers.  The WSGI application can use those endpoints to get the
-    handler for that URL.  It doesn't have to be a string at all but it's
-    recommended.
-
-    Now it's possible to create a URL adapter for one of the subdomains and
-    build URLs:
-
-    >>> c = m.bind('example.com')
-    >>> c.build("kb/browse", dict(id=42))
-    'http://kb.example.com/browse/42/'
-    >>> c.build("kb/browse", dict())
-    'http://kb.example.com/browse/'
-    >>> c.build("kb/browse", dict(id=42, page=3))
-    'http://kb.example.com/browse/42/3'
-    >>> c.build("static/about")
-    '/about'
-    >>> c.build("static/index", force_external=True)
-    'http://www.example.com/'
-
-    >>> c = m.bind('example.com', subdomain='kb')
-    >>> c.build("static/about")
-    'http://www.example.com/about'
-
-    The first argument to bind is the server name *without* the subdomain.
-    Per default it will assume that the script is mounted on the root, but
-    often that's not the case so you can provide the real mount point as
-    second argument:
-
-    >>> c = m.bind('example.com', '/applications/example')
-
-    The third argument can be the subdomain, if not given the default
-    subdomain is used.  For more details about binding have a look at the
-    documentation of the `MapAdapter`.
-
-    And here is how you can match URLs:
-
-    >>> c = m.bind('example.com')
-    >>> c.match("/")
-    ('static/index', {})
-    >>> c.match("/about")
-    ('static/about', {})
-    >>> c = m.bind('example.com', '/', 'kb')
-    >>> c.match("/")
-    ('kb/index', {})
-    >>> c.match("/browse/42/23")
-    ('kb/browse', {'id': 42, 'page': 23})
-
-    If matching fails you get a `NotFound` exception, if the rule thinks
-    it's a good idea to redirect (for example because the URL was defined
-    to have a slash at the end but the request was missing that slash) it
-    will raise a `RequestRedirect` exception.  Both are subclasses of the
-    `HTTPException` so you can use those errors as responses in the
-    application.
-
-    If matching succeeded but the URL rule was incompatible to the given
-    method (for example there were only rules for `GET` and `HEAD` and
-    routing system tried to match a `POST` request) a `MethodNotAllowed`
-    exception is raised.

-    """A Rule represents one URL pattern.  There are some options for `Rule`
-    that change the way it behaves and are passed to the `Rule` constructor.
-    Note that besides the rule-string all arguments *must* be keyword arguments
-    in order to not break the application on Werkzeug upgrades.
-
-    `string`
-        Rule strings basically are just normal URL paths with placeholders in
-        the format ```` where the converter and the
-        arguments are optional.  If no converter is defined the `default`
-        converter is used which means `string` in the normal configuration.
-
-        URL rules that end with a slash are branch URLs, others are leaves.
-        If you have `strict_slashes` enabled (which is the default), all
-        branch URLs that are matched without a trailing slash will trigger a
-        redirect to the same URL with the missing slash appended.
-
-        The converters are defined on the `Map`.
-
-    `endpoint`
-        The endpoint for this rule. This can be anything. A reference to a
-        function, a string, a number etc.  The preferred way is using a string
-        because the endpoint is used for URL generation.
-
-    `defaults`
-        An optional dict with defaults for other rules with the same endpoint.
-        This is a bit tricky but useful if you want to have unique URLs::
-
-            url_map = Map([
-                Rule('/all/', defaults={'page': 1}, endpoint='all_entries'),
-                Rule('/all/page/', endpoint='all_entries')
-            ])
-
-        If a user now visits ``http://example.com/all/page/1`` he will be
-        redirected to ``http://example.com/all/``.  If `redirect_defaults` is
-        disabled on the `Map` instance this will only affect the URL
-        generation.
-
-    `subdomain`
-        The subdomain rule string for this rule. If not specified the rule
-        only matches for the `default_subdomain` of the map.  If the map is
-        not bound to a subdomain this feature is disabled.
-
-        Can be useful if you want to have user profiles on different subdomains
-        and all subdomains are forwarded to your application::
-
-            url_map = Map([
-                Rule('/', subdomain='', endpoint='user/homepage'),
-                Rule('/stats', subdomain='', endpoint='user/stats')
-            ])
-
-    `methods`
-        A sequence of http methods this rule applies to.  If not specified, all
-        methods are allowed. For example this can be useful if you want different
-        endpoints for `POST` and `GET`.  If methods are defined and the path
-        matches but the method matched against is not in this list or in the
-        list of another rule for that path the error raised is of the type
-        `MethodNotAllowed` rather than `NotFound`.  If `GET` is present in the
-        list of methods and `HEAD` is not, `HEAD` is added automatically.
-
-    `strict_slashes`
-        Override the `Map` setting for `strict_slashes` only for this rule. If
-        not specified the `Map` setting is used.
-
-    `merge_slashes`
-        Override :attr:`Map.merge_slashes` for this rule.
-
-    `build_only`
-        Set this to True and the rule will never match but will create a URL
-        that can be build. This is useful if you have resources on a subdomain
-        or folder that are not handled by the WSGI application (like static data)

-    `redirect_to`
-        If given this must be either a string or callable.  In case of a
-        callable it's called with the url adapter that triggered the match and
-        the values of the URL as keyword arguments and has to return the target
-        for the redirect, otherwise it has to be a string with placeholders in
-        rule syntax::
-
-            def foo_with_slug(adapter, id):
-                # ask the database for the slug for the old id.  this of
-                # course has nothing to do with werkzeug.
-                return 'foo/' + Foo.get_slug_for_id(id)

-                Rule('/foo/', endpoint='foo'),

-                Rule('/other/old/url/', redirect_to=foo_with_slug)
-            ])
-
-        When the rule is matched the routing system will raise a
-        `RequestRedirect` exception with the target for the redirect.
-
-        Keep in mind that the URL will be joined against the URL root of the
-        script so don't use a leading slash on the target URL unless you
-        really mean root of that domain.
-
-    `alias`
-        If enabled this rule serves as an alias for another rule with the same
-        endpoint and arguments.
-
-    `host`
-        If provided and the URL map has host matching enabled this can be
-        used to provide a match rule for the whole host.  This also means
-        that the subdomain feature is disabled.
-
-    `websocket`
-        If ``True``, this rule is only matches for WebSocket (``ws://``,
-        ``wss://``) requests. By default, rules will only match for HTTP
-        requests.

-
-        - you receive a `NotFound` exception that indicates that no URL is
-          matching.  A `NotFound` exception is also a WSGI application you
-          can call to get a default page not found page (happens to be the
-          same object as `werkzeug.exceptions.NotFound`)
-
-        - you receive a `MethodNotAllowed` exception that indicates that there
-          is a match for this URL but not for the current request method.
-          This is useful for RESTful applications.
-
-        - you receive a `RequestRedirect` exception with a `new_url`
-          attribute.  This exception is used to notify you about a request
-          Werkzeug requests from your WSGI application.  This is for example the
-          case if you request ``/foo`` although the correct URL is ``/foo/``
-          You can use the `RequestRedirect` instance as response-like object
-          similar to all other subclasses of `HTTPException`.
-
-        - you receive a ``WebsocketMismatch`` exception if the only
-          match is a WebSocket rule but the bind is an HTTP request, or
-          if the match is an HTTP rule but the bind is a WebSocket
-          request.
-
-        - you get a tuple in the form ``(endpoint, arguments)`` if there is
-          a match (unless `return_rule` is True, in which case you get a tuple
-          in the form ``(rule, arguments)``)
-
-        If the path info is not passed to the match method the default path
-        info of the map is used (defaults to the root URL if not defined
-        explicitly).
-
-        All of the exceptions raised are subclasses of `HTTPException` so they
-        can be used as WSGI responses. They will all render generic error or
-        redirect pages.
-
-        Here is a small example for matching:
-
-        >>> m = Map([
-        ...     Rule('/', endpoint='index'),

-        ('index', {})
-        >>> urls.match("/downloads/42")
-        ('downloads/show', {'id': 42})
-
-        And here is what happens on redirect and missing URLs:

-        :param return_rule: return the rule that matched instead of just the

-
-        The `build` function also accepts an argument called `force_external`
-        which, if you set it to `True` will force external URLs. Per default

-    werkzeug.serving
-    ~~~~~~~~~~~~~~~~
-
-    There are many ways to serve a WSGI application.  While you're developing
-    it you usually don't want a full blown webserver like Apache but a simple
-    standalone one.  From Python 2.5 onwards there is the `wsgiref`_ server in
-    the standard library.  If you're using older versions of Python you can
-    download the package from the cheeseshop.
-
-    However there are some caveats. Sourcecode won't reload itself when
-    changed and each time you kill the server using ``^C`` you get an
-    `KeyboardInterrupt` error.  While the latter is easy to solve the first
-    one can be a pain in the ass in some situations.
-
-    The easiest way is creating a small ``start-myproject.py`` that runs the
-    application::
-
-        #!/usr/bin/env python
-        # -*- coding: utf-8 -*-
-        from myproject import make_app
-        from werkzeug.serving import run_simple
-
-        app = make_app(...)
-        run_simple('localhost', 8080, app, use_reloader=True)
-
-    You can also pass it a `extra_files` keyword argument with a list of
-    additional files (like configuration files) you want to observe.
-
-    For bigger applications you should consider using `click`
-    (http://click.pocoo.org) instead of a simple start file.

-    :param reloader_type: the type of reloader to use.  The default is
-                          auto detection.  Valid values are ``'stat'`` and
-                          ``'watchdog'``. See :ref:`reloader` for more

-                               This means that the server will die on errors but
-                               it can be useful to hook debuggers in (pdb etc.)
-    :param ssl_context: an SSL context for the connection. Either an

-
-    The signature of this class is also used in some other places as of
-    Werkzeug 0.5 (:func:`create_environ`, :meth:`BaseResponse.from_values`,
-    :meth:`Client.open`).  Because of this most of the functionality is
-    available through the constructor alone.
-
-    Files and regular form data can be manipulated independently of each
-    other with the :attr:`form` and :attr:`files` attributes, but are
-    passed with the same argument to the constructor: `data`.
-
-    `data` can be any of these values:
-
-    -   a `str` or `bytes` object: The object is converted into an
-        :attr:`input_stream`, the :attr:`content_length` is set and you have to
-        provide a :attr:`content_type`.
-    -   a `dict` or :class:`MultiDict`: The keys have to be strings. The values
-        have to be either any of the following objects, or a list of any of the
-        following objects:
-
-        -   a :class:`file`-like object:  These are converted into
-            :class:`FileStorage` objects automatically.
-        -   a `tuple`:  The :meth:`~FileMultiDict.add_file` method is called
-            with the key and the unpacked `tuple` items as positional
-            arguments.
-        -   a `str`:  The string is set as form data for the associated key.
-    -   a file-like object: The object content is loaded in memory and then
-        handled like a regular `str` or a `bytes`.
-
-    :param path: the path of the request.  In the WSGI environment this will
-                 end up as `PATH_INFO`.  If the `query_string` is not defined
-                 and there is a question mark in the `path` everything after
-                 it is used as query string.
-    :param base_url: the base URL is a URL that is used to extract the WSGI
-                     URL scheme, host (server name + server port) and the
-                     script root (`SCRIPT_NAME`).
-    :param query_string: an optional string or dict with URL parameters.
-    :param method: the HTTP method to use, defaults to `GET`.
-    :param input_stream: an optional input stream.  Do not specify this and

-    werkzeug.urls
-    ~~~~~~~~~~~~~
-
-    ``werkzeug.urls`` used to provide several wrapper functions for Python 2
-    urlparse, whose main purpose were to work around the behavior of the Py2
-    stdlib and its lack of unicode support. While this was already a somewhat
-    inconvenient situation, it got even more complicated because Python 3's
-    ``urllib.parse`` actually does handle unicode properly. In other words,
-    this module would wrap two libraries with completely different behavior. So
-    now this module contains a 2-and-3-compatible backport of Python 3's
-    ``urllib.parse``, which is mostly API-compatible.

-werkzeug.wrappers
-~~~~~~~~~~~~~~~~~
-
-The wrappers are simple request and response objects which you can
-subclass to do whatever you want them to do.  The request object contains
-the information transmitted by the client (webbrowser) and the response
-object contains all the information sent back to the browser.
-
-An important detail is that the request object is created with the WSGI
-environ and will act as high-level proxy whereas the response object is an
-actual WSGI application.
-
-Like everything else in Werkzeug these objects will work correctly with
-unicode data.  Incoming form data parsed by the response object will be
-decoded into an unicode object if possible and if it makes sense.

-
-        class Request(BaseRequest, ETagRequestMixin):
-            pass
-
-    Request objects are **read only**.  As of 0.5 modifications are not
-    allowed in any place.  Unlike the lower level parsing functions the
-    request object will use immutable objects everywhere possible.
-
-    Per default the request object will assume all the text data is `utf-8`
-    encoded.  Please refer to :doc:`the unicode chapter ` for more
-    details about customizing the behavior.
-
-    Per default the request object will be added to the WSGI
-    environment as `werkzeug.request` to support the debugging system.
-    If you don't want that, set `populate_request` to `False`.
-
-    If `shallow` is `True` the environment is initialized as shallow
-    object around the environ.  Every operation that would modify the
-    environ in any way (such as consuming form data) raises an exception
-    unless the `shallow` attribute is explicitly set to `False`.  This
-    is useful for middlewares where you don't want to consume the form
-    data by accident.  A shallow request is not populated to the WSGI
-    environment.

-class BaseResponse(object):
-    """Base response class.  The most important fact about a response object
-    is that it's a regular WSGI application.  It's initialized with a couple
-    of response parameters (headers, body, status code etc.) and will start a
-    valid WSGI response when called with the environ and start response
-    callable.
-
-    Because it's a WSGI application itself processing usually ends before the
-    actual response is sent to the server.  This helps debugging systems
-    because they can catch all the exceptions before responses are started.
-
-    Here a small example WSGI application that takes advantage of the
-    response objects::
-
-        from werkzeug.wrappers import BaseResponse as Response
-
-        def index():
-            return Response('Index page')
-
-        def application(environ, start_response):
-            path = environ.get('PATH_INFO') or '/'
-            if path == '/':
-                response = index()
-            else:
-                response = Response('Not Found', status=404)
-            return response(environ, start_response)
-
-    Like :class:`BaseRequest` which object is lacking a lot of functionality
-    implemented in mixins.  This gives you a better control about the actual
-    API of your response objects, so you can create subclasses and add custom
-    functionality.  A full featured response object is available as
-    :class:`Response` which implements a couple of useful mixins.
-
-    To enforce a new type of already existing responses you can use the
-    :meth:`force_type` method.  This is useful if you're working with different
-    subclasses of response objects and you want to post process them with a
-    known interface.
-
-    Per default the response object will assume all the text data is `utf-8`
-    encoded.  Please refer to :doc:`the unicode chapter ` for more
-    details about customizing the behavior.
-
-    Response can be any kind of iterable or string.  If it's a string it's
-    considered being an iterable with one item which is the string passed.
-    Headers can be a list of tuples or a
-    :class:`~werkzeug.datastructures.Headers` object.
-
-    Special note for `mimetype` and `content_type`:  For most mime types
-    `mimetype` and `content_type` work the same, the difference affects
-    only 'text' mimetypes.  If the mimetype passed with `mimetype` is a
-    mimetype starting with `text/`, the charset parameter of the response
-    object is appended to it.  In contrast the `content_type` parameter is
-    always added as header unmodified.
-
-    .. versionchanged:: 0.5

-                               unchanged (see :func:`wrap_file` for more
