Mirroring will create a copy of a source filesystem on a destination filesystem. If there are no files on the destination, then mirroring is simply a straight copy. If there are any files or directories on the destination they may be deleted or modified to match the source. In order to avoid redundant copying of files, `mirror` can compare timestamps, and only copy files with a newer modified date. This timestamp comparison is only done if the file sizes are different. This scheme will work if you have mirrored a directory previously, and you would like to copy any changes. Otherwise you should set the ``copy_if_newer`` parameter to `False` to guarantee an exact copy, at the expense of potentially copying extra files. )print_function)unicode_literalsN)Copier)copy_file_internal)ResourceNotFound manage_fs)is_thread_safe)Walker)CallableOptionalTextUnion)FS)InfocCs4|j|jkrdS|j}|j}|dup|dup||kS)zCompare two `Info` objects to see if they should be copied.

Mirroring a filesystem will create an exact copy of ``src_fs`` on ``dst_fs``, by removing any files / directories on the destination that aren't on the source, and copying files that aren't. Arguments: src_fs (FS or str): Source filesystem (URL or instance). dst_fs (FS or str): Destination filesystem (URL or instance). walker (~fs.walk.Walker, optional): An optional walker instance. copy_if_newer (bool): Only copy newer files (the default). workers (int): Number of worker threads used (0 for single threaded). Set to a relatively low number for network filesystems, 4 would be a good start. c tddS)NF)Z writeablerr)src_fsrrsrcN zmirror..srccr)NT)Zcreaterr)dst_fsrrdstQrzmirror..dstr)Z num_workers)walker copy_if_newer copy_fileN)lockr r_mirrorcopy) rrrrZworkersrrZ_src_fsZ_dst_fsZ _thread_safeZcopierr)rrrmirror6s(   Pr"c CsL|pt}|j|dgd}|D]\}}}zdd|j|dgdD} Wnty3||i} Ynw|D]*} | |} | | jd} | durY| jrQ| | n|rYt | | sYq6||| || q6|D]"} | |} | | jd}|dur~|js}| | qc|j| ddqc| r| \}}||} |jr| | n| | | sqdS)NZdetails)Z namespacescSsi|]}|j|qSr)name).0inforrr isz_mirror..T)Zrecreate) r walkscandirrZmakedirZ make_pathpopr#is_dirZ removetreerremovepopitem)rrrrrr'pathdirsfilesrZ_file_pathZdst_fileZ_dirZdst_dir_r%rrrr asJ           r )NTr)__doc__Z __future__rrtypingZ_bulkrr!rerrorsrZopenerr Ztoolsr r'r Z TYPE_CHECKINGr r rrbaserr%rrr"r rrrrs*           ,
