It uses the :mod:`profile` or :mod:`cProfile` module to do the profiling and writes the stats to the stream provided (defaults to stderr). Example usage:: from werkzeug.contrib.profiler import ProfilerMiddleware app = ProfilerMiddleware(app) :copyright: (c) 2014 by the Werkzeug Team, see AUTHORS for more details. :license: BSD, see LICENSE for more details. i����N( t Profile( t Statst MergeStreamc B s e Z d Z d � Z d � Z RS( s� An object that redirects `write` calls to multiple streams. Use this to log to both `sys.stdout` and a file:: f = open('profiler.log', 'w') stream = MergeStream(sys.stdout, f) profiler = ProfilerMiddleware(app, stream) c G s" | s t d � � n | | _ d S( Ns! at least one stream must be given( t TypeErrort streams( t selfR ( ( sH /opt/imh-python/lib/python2.7/site-packages/werkzeug/contrib/profiler.pyt __init__( s c C s% x | j D] } | j | � q Wd S( N( R t write( R t datat stream( ( sH /opt/imh-python/lib/python2.7/site-packages/werkzeug/contrib/profiler.pyR - s ( t __name__t __module__t __doc__R R ( ( ( sH /opt/imh-python/lib/python2.7/site-packages/werkzeug/contrib/profiler.pyR s t ProfilerMiddlewarec B s, e Z d Z d d d d d � Z d � Z RS( s Simple profiler middleware. Wraps a WSGI application and profiles a request. This intentionally buffers the response so that timings are more exact. By giving the `profile_dir` argument, pstat.Stats files are saved to that directory, one file per request. Without it, a summary is printed to `stream` instead. For the exact meaning of `sort_by` and `restrictions` consult the :mod:`profile` documentation. .. versionadded:: 0.9 Added support for `restrictions` and `profile_dir`. :param app: the WSGI application to profile. :param stream: the stream for the profiled stats. defaults to stderr. :param sort_by: a tuple of columns to sort the result by. :param restrictions: a tuple of profiling strictions, not used if dumping to `profile_dir`. :param profile_dir: directory name to save pstat files t timet callsc C sO t s t d � � n | | _ | p* t j | _ | | _ | | _ | | _ d S( NsH the profiler is not available because profile or pstat is not installed.( t availablet RuntimeErrort _appt syst stdoutt _streamt _sort_byt _restrictionst _profile_dir( R t appR t sort_byt restrictionst profile_dir( ( sH /opt/imh-python/lib/python2.7/site-packages/werkzeug/contrib/profiler.pyR I s c sr g � d � � f d � � � � � � f d � } t � } t j � } | j | � d j � � } t j � | } � j d k r� t j j � j d � d � j d � j d � j d d � p� d | d t j � f � } | j | � n~ t | d � j �} | j � j � � j j d d � � j j d � j d � � | j � j � � j j d d d � | g S( Nc s � | | | � � j S( N( t append( t statust headerst exc_info( t response_bodyt start_response( sH /opt/imh-python/lib/python2.7/site-packages/werkzeug/contrib/profiler.pyt catching_start_responseW s c s? � j � � � } � j | � t | d � r; | j � n d S( Nt close( R t extendt hasattrR$ ( t appiter( R# t environR!
