It is a "friend" of that class, and imports data either by direct access to members of Profile class, or by reading in a dictionary that was emitted (via marshal) from the Profile class. The big change from the previous Profiler (in terms of raw functionality) is that an "add()" method has been provided to combine Stats from several distinct profile runs. Both the constructor and the add() method now take arbitrarily many file names as arguments. All the print methods now take an argument that indicates how many lines to print. If the arg is a floating point number between 0 and 1.0, then it is taken as a decimal percentage of the available lines to be printed (e.g., .1 means print 10% of all available lines). If it is an integer, it is taken to mean the number of lines of data that you wish to have printed. The sort_stats() method now processes some additional options (i.e., in addition to the old -1, 0, 1, or 2 that are respectively interpreted as 'stdname', 'calls', 'time', and 'cumulative'). It takes either an arbitrary number of quoted strings or SortKey enum to select the sort order. For example sort_stats('time', 'name') or sort_stats(SortKey.TIME, SortKey.NAME) sorts on the major key of 'internal function time', and on the minor key of 'the name of the function'. Look at the two tables in sort_stats() and get_sort_arg_defs(self) for more examples. All methods return self, so you can string together commands like: Stats('foo', 'goo').strip_dirs().sort_stats('calls'). print_stats(5).print_callers(5) N)�streamc G sF |pt j| _t|�sd }n|d }|dd � }| �|� | j|� d S r )�sys�stdoutr" �len�init�add)�selfr" �args�argr r r �__init__Y s zStats.__init__c C s� d | _ g | _d | _d| _d| _d| _d| _t� | _i | _ i | _ | � |� z | � � W n8 t k r� td| jrx| jd nd | jd� � Y nX d S )Nr zInvalid timing data %s���� ��file)� all_callees�files�fcn_list�total_tt� total_calls� prim_calls� max_name_len�set� top_level�stats� sort_arg_dict� load_stats�get_top_level_stats� Exception�printr" )r( r* r r r r& c s( ��z Stats.initc C s� |d kri | _ d S t|t�rxt|d��}t�|�| _ W 5 Q R X z"t�|�}t� |j �d | }W n Y nX |g| _ n t |d�r�|� � |j | _ i |_ | j s�td| j|f ��d S )N�rbz � create_statsz.Cannot create or construct a %r object from %r)r9 � isinstancer �open�marshal�load�os�statr �ctime�st_mtimer1 �hasattrr@ � TypeError� __class__)r( r* �fZ file_statsr r r r; v s* �zStats.load_statsc C s� | j �� D ]p\}\}}}}}| j|7 _| j|7 _| j|7 _d|krZ| j�|� tt|��| j kr tt|��| _ q d S )N)Zjprofiler Zprofiler) r9 �itemsr4 r5 r3 r8 r' r% �func_std_stringr6 )r( �func�cc�nc�tt�ct�callersr r r r< � s zStats.get_top_level_statsc G s� |s| S t |�D ]�}t| �t|�kr,t|�}| j|j7 _| j|j7 _| j|j7 _| j|j7 _|jD ]}| j�|� qr| j |j k r�|j | _ d | _ |j � � D ]<\}}|| j kr�| j | }nddddi f}t ||�| j |< q�q| S �Nr )�reversed�typer r1 r4 r5 r3 r8 r' r6 r2 r9 rM �add_func_stats)r( �arg_list�itemrO rF Z old_func_statr r r r' � s( z Stats.addc C s( t |d��}t�| j|� W 5 Q R X dS )z:Write the profile data to a file we know how to load back.�wbN)rB rC �dumpr9 )r( r rL r r r � dump_stats� s zStats.dump_stats)))r r, z call count)))� r, zcumulative time))�� r z file name))�� r z line number))�� r z function name))rc r_ ra zname/file/line)))r r, zprimitive call count)))� r z standard name)))� r, z internal time) r r r r r r r r r r r r r c C st | j sni | _ }i }| j�� D ]>\}}|}|r |s4q ||krFd||< q |||< |dd� }q*q |D ] }||= qb| j S )z)Expand all abbreviations that are unique.r Nr, )r: �sort_arg_dict_defaultrM )r( �dictZbad_list�word�tupZfragmentr r r �get_sort_arg_defs� s zStats.get_sort_arg_defsc G s\ |sd| _ | S t|�dkrBt|d t�rBddddd�|d g}n:t|�dkr||dd � D ] }t|�t|d �krZtd ��qZ| �� }d }d | _d }|D ]B}t|t�r�|j }||| d }| j||| d 7 _d }q�g }| j � � D ]4\}\} } } } } |� | | | | f| t |�|f � q�|jtt|�j�d � g | _ }|D ]}|� |d � �qB| S )Nr r r r r r )r, r r rf rf z Can't have mixed argument typer r- z, )�keyr, )r2 r% rA �intrW rJ rk � sort_typer �valuer9 rM �appendrN �sortr � TupleComp�compare)r( Zfieldr* Z sort_arg_defsZ sort_tupleZ connectorri Z stats_listrO rP rQ rR rS rT r2 �tupler r r � sort_stats� sF �� � zStats.sort_statsc C s | j r| j �� | S �N)r2 �reverse�r( r r r � reverse_order s zStats.reverse_orderc C s� | j }i | _ }d}|�� D ]�\}\}}}}} t|�} tt| ��|krRtt| ��}i } | �� D ]\} } | | t| �< q^| |kr�t|| ||||| f�|| < q ||||| f|| < q | j}t� | _}|D ]}|�t|�� q�|| _ d | _ d | _ | S rU ) r9 rM �func_strip_pathr% rN rX r8 r7 r' r6 r2 r0 )r( ZoldstatsZnewstatsr6 rO rP rQ rR rS rT ZnewfuncZ newcallers�func2�callerZold_topZnew_topr r r � strip_dirs s0 � zStats.strip_dirsc C st | j r d S i | _ }| j�� D ]P\}\}}}}}||kr@i ||< |�� D ]$\}} ||kr`i ||< | || |< qHq d S rv )r0 r9 rM ) r( r0 rO rP rQ rR rS rT r{ r| r r r � calc_callees# s zStats.calc_calleesc C s |}t |t�rpzt�|�}W n* tjk rF |d| 7 }||f Y S X g }|D ] }|�t|��rP|�|� qPnzt|�}t |t �r�d| kr�dk r�n n t || d �}|d |� }n2t |t �r�d| kr�|k r�n n|}|d |� }t|�t|�k�r|dt|�t|�|f 7 }||fS )Nz# <Invalid regular expression %r> g g �?g �?r z6 List reduced from %r to %r due to restriction <%r> ) rA r �re�compile�error�searchrN rp r% �floatrm )r( Zsel�list�msgZnew_listZrexrO �countr r r �eval_print_amount6 s2 "" �zStats.eval_print_amountc C s� | j }| jr*| jd d � }d| j d }nt| j�� �}d}|D ]}| �|||�\}}q@t|�}|sld|fS t|| j d� |t| j�k r�d}|D ] }tt |��|kr�tt |��}q�|d |fS )Nz Ordered by: � z!
