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). r )�writer �argv)�outfiler r r �_usageS s *r z#pragma NO COVERz ^\s*(#.*)?$c @ s. e Z d Z d d d d � Z d d � Z d S)�_IgnoreNc C sT | s t � n t | � | _ | s* g n d d � | D� | _ i d d 6| _ d S)Nc S s" g | ] } t j j | � � q Sr )�os�path�normpath)�.0�dr r r � <listcomp>� s z$_Ignore.__init__.<locals>.<listcomp>� z<string>)�set�_mods�_dirs�_ignore)�self�modules�dirsr r r �__init__� s z_Ignore.__init__c C s� | | j k r | j | S| | j k r: d | j | <d Sx5 | j D]* } | j | d � rD d | j | <d SqD W| d k r� d | j | <d Sx8 | j D]- } | j | t j � r� d | j | <d Sq� Wd | j | <d S)Nr �.r )r r � startswithr r �sep)r �filename� modulename�modr r r r �names� s$ z _Ignore.names)�__name__� __module__� __qualname__r" r) r r r r r � s r c C s. t j j | � } t j j | � \ } } | S)z-Return a plausible module name for the patch.)r r �basename�splitext)r �baser& �extr r r �_modname� s r1 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 d � } n | } t j j | � \ } } | j t j d � } t j r| j t j d � } n t j j | � \ } } | j d � S)z,Return a plausible module name for the path.� r Nr# ) r r �normcaser r$ �lenr% � splitdrive�replace�altsepr. �lstrip)r Z comparepathZlongest�dirr/ Zdriver& r0 r r r � _fullmodname� s ( r: c @ sg e Z d Z d d d d d d d � Z d d � Z d d � Z d d d d d � Z d d d � Z d S)r Nc C sY | | _ | 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 rUyD t j t | j d � � \ } } } | j | j | | | � � WqUt t t f k rQ} z% t d | j | f d t j �WYd d } ~ XqUXn d S)N�rbzSkipping counts file %r: %s�file)�counts�copyZcounter� calledfuncs�callers�infiler �pickle�load�open�update� __class__�OSError�EOFError� ValueError�printr �stderr)r r= r? rA r@ r �errr r r r" � s* $ zCoverageResults.__init__c C s | j d � o | j d � S)z_Return True if the filename does not refer to a file we want to have reported. �<�>)r$ �endswith)r r& r r r �is_ignored_filename� s z#CoverageResults.is_ignored_filenamec C s� | j } | j } | j } | j } | j } | j } x, | D]$ } | j | d � | | | | <q= Wx | D] } d | | <ql Wx | D] } d | | <q� Wd S)z.Merge in the data from another CoverageResultsr r N)r= r? r@ �get) r �otherr= r? r@ Z other_countsZother_calledfuncsZ other_callers�keyr r r rE � s " zCoverageResults.updateTFc !
