Arguments: f1 -- First file name f2 -- Second file name shallow -- Just check stat signature (do not read the files). defaults to True. Return value: True if the files are the same, False otherwise. This function uses a cache for past comparisons and the results, with cache entries invalidated if their stat information changes. The cache may be cleared by calling clear_cache(). r FT� N�d ) �_sig�os�stat�S_IFREGr �get�_do_cmp�lenr )�f1�f2�shallow�s1�s2Zoutcomer r r r s c C s t j| j�| j| jfS )N)r �S_IFMT�st_mode�st_size�st_mtime)�str r r r D s r c C sb t }t| d��J}t|d��4}x,|j|�}|j|�}||kr>dS |s dS q W W d Q R X W d Q R X d S )N�rbFT)�BUFSIZE�open�read)r r �bufsize�fp1�fp2Zb1Zb2r r r r I s r c @ s� e Zd ZdZddd�Zdd� Zdd� Zd d � Zd d � Zd d� Z dd� Z dd� Z dd� Z dd� Z ee eeeeeeeeeeed� Zdd� ZdS )r aM 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 DEFAULT_IGNORES. 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.
