In all cases this routine attempts to "exec" its first argument and gather profiling statistics from the execution. If no file name is present, then this function automatically prints a simple profiling report, sorted by the standard name string (file/line/function-name) that is presented in each line.

Each such tuple corresponds to a stack frame that is currently active (self.cur[-2]). The following are the definitions of its members. We use this external "parallel stack" to avoid contaminating the program that we are profiling. (old profiler used to write into the frames local dictionary!!) Derived classes can change the definition of some entries, as long as they leave [-2:] intact (frame and previous tuple). In case an internal error is detected, the -3 element is used as the function name. [ 0] = Time that needs to be charged to the parent frame's function. It is used so that a function call will not have to access the timing data for the parent frame. [ 1] = Total time spent in this frame's function, excluding time in subfunctions (this latter is tallied in cur[2]). [ 2] = Total time spent in subfunctions, excluding time executing the frame's function (this latter is tallied in cur[1]). [-3] = Name of the function that corresponds to this frame. [-2] = Actual frame that we correspond to (used to sync exception handling). [-1] = Our parent 6-tuple (corresponds to frame.f_back). Timing data for each function is stored as a 5-tuple in the dictionary self.timings[]. The index is always the name stored in self.cur[-3]. The following are the definitions of the members: [0] = The number of times this function was called, not counting direct or indirect recursion, [1] = Number of times this function appears on the stack, minus one [2] = Total time spent internal to this function [3] = Cumulative time that this function was present on the stack. In non-recursive functions, this is the total execution time from start to finish of each invocation of a function, including time spent in all subfunctions. [4] = A dictionary indicating for each function name, the number of times it was called by us. i c C s i | _ d | _ d | _ d | _ | d k r< | j } n | | _ | sm t j | _ | _ | j | _ n� | | _ | j � } y t | � } Wn' t k r� | | _ | j | _ YnC X| d k r� | j | _ n | j | _ | t d d � } | | _ | j � | _ | j d � d S( Nu i c S s | | � � S( N( ( u timeru sum( ( u, /opt/alt/python33/lib64/python3.3/profile.pyu get_time_timer� s u( Profile.__init__.<locals>.get_time_timeru profiler( u timingsu Noneu curu cmdu c_func_nameu biasu timeu process_timeu timeru get_timeu trace_dispatch_iu dispatcheru lenu TypeErroru trace_dispatchu trace_dispatch_lu sumu tu simulate_call( u selfu timeru biasu tu lengthu get_time_timer( ( u, /opt/alt/python33/lib64/python3.3/profile.pyu __init__ s0 u Profile.__init__c C s� | j } | � } | d | d | j | j } | d k rM | j | _ n | j | | | | � r� | � } | d | d | _ n" | � } | d | d | | _ d S( Ni i u c_call( u timeru tu biasu __name__u c_func_nameu dispatch( u selfu frameu eventu argu timeru tu r( ( u, /opt/alt/python33/lib64/python3.3/profile.pyu trace_dispatch� s u Profile.trace_dispatchc C sw | j } | � | j | j } | d k r; | j | _ n | j | | | | � rc | � | _ n | � | | _ d S( Nu c_call( u timeru tu biasu __name__u c_func_nameu dispatch( u selfu frameu eventu argu timeru t( ( u, /opt/alt/python33/lib64/python3.3/profile.pyu trace_dispatch_i� s u Profile.trace_dispatch_ic C s� | j } | � d | j | j } | d k r? | j | _ n | j | | | | � rk | � d | _ n | � d | | _ d S( Ng N@u c_call( u timeru tu biasu __name__u c_func_nameu dispatch( u selfu frameu eventu argu timeru t( ( u, /opt/alt/python33/lib64/python3.3/profile.pyu trace_dispatch_mac� s u Profile.trace_dispatch_macc C sw | j } | � | j | j } | d k r; | j | _ n | j | | | | � rc | � | _ n | � | | _ d S( Nu c_call( u get_timeu tu biasu __name__u c_func_nameu dispatch( u selfu frameu eventu argu get_timeu t( ( u, /opt/alt/python33/lib64/python3.3/profile.pyu trace_dispatch_l� s u Profile.trace_dispatch_lc C s` | j \ } } } } } } | | k r= | r= | j | | � S| | | | | | | f | _ d S( Ni ( u curu trace_dispatch_return( u selfu frameu tu rptu ritu retu rfnu rframeu rcur( ( u, /opt/alt/python33/lib64/python3.3/profile.pyu trace_dispatch_exception� s u Profile.trace_dispatch_exceptionc C s | j rb | j | j d k rb | j \ } } } } } } t | t j � sb | j | d � qb n | j } | j | j | j f } | d d | | | j f | _ | j } | | k r� | | \ } } } } } | | d | | | f | | <n d d d d i f | | <d S( Ni i i i����( u curu f_backu isinstanceu Profileu fake_frameu trace_dispatch_returnu f_codeu co_filenameu co_firstlinenou co_nameu timings( u selfu frameu tu rptu ritu retu rfnu rframeu rcuru fcodeu fnu timingsu ccu nsu ttu ctu callers( ( u, /opt/alt/python33/lib64/python3.3/profile.pyu trace_dispatch_call� s u Profile.trace_dispatch_callc C s� d d | j f } | d d | | | j f | _ | j } | | k r~ | | \ } } } } } | | d | | | f | | <n d d d d i f | | <d S( Nu i i ( u c_func_nameu curu timings( u selfu frameu tu fnu timingsu ccu nsu ttu ctu callers( ( u, /opt/alt/python33/lib64/python3.3/profile.pyu trace_dispatch_c_call s u Profile.trace_dispatch_c_callc C s& | | j d k r- | j | j d d � n | j \ } } } } } } | | } | | } | \ } } } } } } | | | | | | | | f | _ | j } | | \ } } } } } | s� | | } | d } n | | k r� | | d | | <n d | | <| | d | | | | f | | <d S( Ni i i i����i����( u curu trace_dispatch_returnu timings( u selfu frameu tu rptu ritu retu rfnu rcuru frame_totalu pptu pitu petu pfnu pframeu pcuru timingsu ccu nsu ttu ctu callers( ( u, /opt/alt/python33/lib64/python3.3/profile.pyu trace_dispatch_return s" #
