Typical uses for censor are due to security or legal requirements, including:: * Passwords, private keys, cryptographic material * Licensed data/code/libraries for which the license has expired * Personally Identifiable Information or other private data Censored nodes can interrupt mercurial's typical operation whenever the excised data needs to be materialized. Some commands, like ``hg cat``/``hg revert``, simply fail when asked to produce censored data. Others, like ``hg verify`` and ``hg update``, must be capable of tolerating censored data to continue to function in a meaningful way. Such commands only tolerate censored file revisions if they are allowed by the "censor.policy=ignore" config option. A few informative commands such as ``hg grep`` will unconditionally ignore censored data and merely report that it was encountered. i ( t absolute_import( t _( t short( t errort registrart scmutils ships-with-hg-coret censort rt revt s# censor file from specified revisiont REVt tt tombstones replacement tombstone datat TEXTs -r REV [-t TEXT] [FILE]t helpcategoryc K@ sC | j � �1 | j � � t | | | | | | � SWd QXWd QXd S( N( t wlockt lockt _docensor( t uit repot pathR R t opts( ( s0 /usr/lib/python2.7/dist-packages/hgext/censor.pyR 3 s c K@ s� | s t j t d � � � n | s< t j t d � � � n | d } t j | | f � } | j � s t | j � � d k r� t j t d � � � n | j � d } | j | � } t | � s� t j t d � � � n t j | | | � j � } y | | } Wn* t k r/t j t d � | � � n Xy | j | � } Wn- t j k rrt j t d � | � � n X| j � } g } xO | j � D]A } | | } | | k r�| j | � | k r�| j | � q�q�W| r3d j g | D] } t | j � � ^ q�� } t j t d � | d t d � �� n | j � } | j � g | D] } | j � ^ qOk r�t j t d � d t d � �� n | j d � � } | j | | d | �Wd QXd S( Ns must specify file path to censors must specify revision to censori s% can only specify an explicit filenamei s" cannot censor file with no historys invalid revision identifier %ss" file does not exist at revision %ss , s cannot censor file in heads (%s)t hints clean/delete and commit firsts cannot censor working directorys clean/delete/update firstR R ( R t AbortR t NoneR t matcht anypatst lent filest filet revsingleR t KeyErrort filectxt LookupErrort filenodet headst appendt joinR t nodet parentst transactiont censorrevision( R R R R R R t wctxt mt flogt ctxt fctxt fnodeR# t headnodet hct ct headlistt wpt pt tr( ( s0 /usr/lib/python2.7/dist-packages/hgext/censor.pyR G sN $ !. + N( t __doc__t __future__R t mercurial.i18nR t mercurial.nodeR t mercurialR R R t cmdtablet commandt testedwitht CATEGORY_MAINTENANCER R ( ( ( s0 /usr/lib/python2.7/dist-packages/hgext/censor.pyt <module> s& !
