Arguments: f1 -- First file name f2 -- Second file name shallow -- Just check stat signature (do not read the files). defaults to 1. Return value: True if the files are the same, False otherwise. This function uses a cache for past comparisons and the results, with a cache invalidation mechanism relying on stale signatures. i i id N( t _sigt ost statt S_IFREGt Falset Truet _cachet gett Nonet _do_cmpt lent clear( t f1t f2t shallowt s1t s2t outcome( ( s /usr/lib64/python2.7/filecmp.pyR s & c C s t j | j � | j | j f S( N( R t S_IFMTt st_modet st_sizet st_mtime( t st( ( s /usr/lib64/python2.7/filecmp.pyR ; s c C s t } t | d � �d } t | d � �L } xB t rn | j | � } | j | � } | | k ra t S| s- t Sq- WWd QXWd QXd S( Nt rb( t BUFSIZEt openR t readR ( R R t bufsizet fp1t fp2t b1t b2( ( s /usr/lib64/python2.7/filecmp.pyR @ s c B s� e Z d Z d d d � Z d � Z d � Z d � Z d � Z d � Z d � Z d � Z d � Z d � Z e d e d e d e d e d e d e d e d e d e d e d e d e � Z d � Z RS( sQ A class that manages the comparison of 2 directories. dircmp(a,b,ignore=None,hide=None) A and B are directories. IGNORE is a list of names to ignore, defaults to ['RCS', 'CVS', 'tags']. HIDE is a list of names to hide, defaults to [os.curdir, os.pardir]. High level usage: x = dircmp(dir1, dir2) x.report() -> prints a report on the differences between dir1 and dir2 or x.report_partial_closure() -> prints report on differences between dir1 and dir2, and reports on common immediate subdirectories. x.report_full_closure() -> like report_partial_closure, but fully recursive. Attributes: left_list, right_list: The files in dir1 and dir2, filtered by hide and ignore. common: a list of names in both dir1 and dir2. left_only, right_only: names only in dir1, dir2. common_dirs: subdirectories in both dir1 and dir2. common_files: files in both dir1 and dir2. common_funny: names in both dir1 and dir2 where the type differs between dir1 and dir2, or the name is not stat-able. same_files: list of identical files. diff_files: list of filenames which differ. funny_files: list of files which could not be compared. subdirs: a dictionary of dircmp objects, keyed by names in common_dirs. c C sm | | _ | | _ | d k r6 t j t j g | _ n | | _ | d k r` d d d g | _ n | | _ d S( Nt RCSt CVSt tags( t leftt rightR R t curdirt pardirt hidet ignore( t selft at bR/ R.
