Application Profiler
====================

This module provides a middleware that profiles each request with the
:mod:`cProfile` module. This can help identify bottlenecks in your code
that may be slowing down your application.

    request. Responses are buffered so that timings are more exact.

    If ``stream`` is given, :class:`pstats.Stats` are written to it
    after each request. If ``profile_dir`` is given, :mod:`cProfile`
    data files are saved to that directory, one file per request.

    The filename can be customized by passing ``filename_format``. If
    it is a string, it will be formatted using :meth:`str.format` with
    the following fields available:

    -   ``{method}`` - The request method; GET, POST, etc.
    -   ``{path}`` - The request path or 'root' should one not exist.
    -   ``{elapsed}`` - The elapsed time of the request.
    -   ``{time}`` - The time of the request.

    If it is a callable, it will be called with the WSGI ``environ``
    dict and should return a filename.

    :param app: The WSGI application to wrap.
    :param stream: Write stats to this stream. Disable with ``None``.
    :param sort_by: A tuple of columns to sort stats by. See
        :meth:`pstats.Stats.sort_stats`.
    :param restrictions: A tuple of restrictions to filter stats by. See
        :meth:`pstats.Stats.print_stats`.
    :param profile_dir: Save profile data files to this directory.
    :param filename_format: Format string for profile data file names,
        or a callable returning a name. See explanation above.

    .. code-block:: python

        from werkzeug.middleware.profiler import ProfilerMiddleware
        app = ProfilerMiddleware(app)

    .. versionchanged:: 0.15
        Stats are written even if ``profile_dir`` is given, and can be
        disable by passing ``stream=None``.

    .. versionadded:: 0.15
        Added ``filename_format``.

    .. versionadded:: 0.9
        Added ``restrictions`` and ``profile_dir``.
