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 i ( t _sigt ost statt S_IFREGt Falset Truet _cachet gett _do_cmp( t f1t f2t shallowt s1t s2t resultt outcome( ( s# /usr/local/lib/python2.5/filecmp.pyR s (c C s t i | i ƒ | i | i f S( N( R t S_IFMTt st_modet st_sizet st_mtime( t st( ( s# /usr/local/lib/python2.5/filecmp.pyR ; s c C sy t } t | d ƒ } t | d ƒ } xN t oF | i | ƒ } | i | ƒ } | | j o t Sn | p t Sq' q' Wd S( Nt rb( t BUFSIZEt openR t readR ( R R t bufsizet fp1t fp2t b1t b2( ( s# /usr/local/lib/python2.5/filecmp.pyR @ s c B sÈ 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 ƒ 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 sq | | _ | | _ | d j o t i t i g | _ n | | _ | d j o d d d g | _ n | | _ d S( Nt RCSt CVSt tags( t leftt rightt NoneR t curdirt pardirt hidet ignore( t selft at bR.
