Otherwise, exactly one of the following three options must be given: -t, --trace Print each line to sys.stdout before it is executed. -c, --count Count the number of times each line is executed and write the counts to <module>.cover for each module executed, in the module's directory. See also `--coverdir', `--file', `--no-report' below. -l, --listfuncs Keep track of which functions are executed at least once and write the results to sys.stdout after the program exits. -T, --trackcalls Keep track of caller/called pairs and write the results to sys.stdout after the program exits. -r, --report Generate a report from a counts file; do not execute any code. `--file' must specify the results file to read, which must have been created in a previous run with `--count --file=FILE'. Modifiers: -f, --file=<file> File to accumulate counts over several runs. -R, --no-report Do not generate the coverage report files. Useful if you want to accumulate over several runs. -C, --coverdir=<dir> Directory where the report files. The coverage report for <package>.<module> is written to file <dir>/<package>/<module>.cover. -m, --missing Annotate executable lines that were not executed with '>>>>>> '. -s, --summary Write a brief summary on stdout for each file. (Can only be used with --count or --report.) -g, --timing Prefix each line with the time since the program started. Only used while tracing. Filters, may be repeated multiple times: --ignore-module=<mod> Ignore the given module(s) and its submodules (if it is a package). Accepts comma separated list of module names --ignore-dir=<dir> Ignore files in the given directory (multiple directories can be joined by os.pathsep). i ( t writeR t argv( t outfile( ( s /usr/lib/python2.7/trace.pyt usageS s *s #pragma NO COVERs ^\s*(#.*)?$t Ignorec B s e Z d d d � Z d � Z RS( c C sM | p g | _ | p g | _ t t j j | j � | _ i d d 6| _ d S( Ni s <string>( t _modst _dirst mapt ost patht normpatht _ignore( t selft modulest dirs( ( s /usr/lib/python2.7/trace.pyt __init__� s c C s� | | j k r | j | Sxk | j D]` } | | k rG d | j | <d St | � } | | | k r$ | | d k r$ d | j | <d Sq$ W| d k r� d | j | <d Sx8 | j D]- } | j | t j � r� d | j | <d Sq� Wd | j | <d S( Ni t .i ( R R t lenR R t startswithR t sep( R t filenamet modulenamet modt nt d( ( s /usr/lib/python2.7/trace.pyt names� s& N( t __name__t __module__R R R ( ( ( s /usr/lib/python2.7/trace.pyR � s c C s. t j j | � } t j j | � \ } } | S( s- Return a plausible module name for the patch.( R R t basenamet splitext( R t baseR t ext( ( s /usr/lib/python2.7/trace.pyt modname� s c C s t j j | � } d } xo t j D]d } t j j | � } | j | � r" | t | � t j k r" t | � t | � k r� | } q� q" q" W| r� | t | � d } n | } t j j | � \ } } | j t j d � } t j r� | j t j d � } n t j j | � \ } } | j d � S( s, Return a plausible module name for the path.t i R ( R R t normcaseR R R R t splitdrivet replacet altsepR$ t lstrip( R t comparepatht longestt dirR% t driveR R& ( ( s /usr/lib/python2.7/trace.pyt fullmodname� s ( t CoverageResultsc B sD e Z d d d d d d � Z d � Z e e d d � Z d � Z RS( c C sA | | _ | j d k r$ i | _ n | j j � | _ | | _ | j d k rZ i | _ n | j j � | _ | | _ | j d k r� i | _ n | j j � | _ | | _ | | _ | j r=yD t j t | j d � � \ } } } | j | j | | | � � Wq=t t t f k r9} t j d | j | f IJq=Xn d S( Nt rbs Skipping counts file %r: %s( t countsR t copyt countert calledfuncst callerst infileR t picklet loadt opent updatet __class__t IOErrort EOFErrort ValueErrorR t stderr( R R5 R8 R: R9 R t err( ( s /usr/lib/python2.7/trace.pyR � s* $ c C s� | j } | j } | j } | j } | j } | j } x2 | j � D]$ } | j | d � | | | | <qC Wx | j � D] } d | | <qx Wx | j � D] } d | | <q� Wd S( s.
