A TarInfo object represents one member in a TarFile. Aside from storing all required attributes of a file (like file type, size, time, permissions, owner etc.), it provides some useful methods to determine its type. It does not contain the file's data itself. TarInfo objects are returned by TarFile's methods ~TarFile.getmember, ~TarFile.getmembers and ~TarFile.gettarinfo. Modifying the objects returned by ~TarFile.getmember or ~TarFile.getmembers will affect all subsequent operations on the archive. For cases where this is unwanted, you can use copy.copy() or call the ~TarInfo.replace method to create a modified copy in one step. Several attributes can be set to None to indicate that a piece of metadata is unused or unknown. Different TarInfo methods handle None differently The ~TarFile.extract or ~TarFile.extractall methods will ignore the corresponding metadata, leaving it set to a default. ~TarFile.addfile will fail. ~TarFile.list will print a placeholder string. Create and return a TarInfo object from string buffer buf. Raises HeaderError if the buffer is invalid. Read the next member from the TarFile object tarfile and return it as a TarInfo object. Create a string buffer from a TarInfo object. For information on the arguments see the constructor of the TarFile class. A TarInfo object has the following public data attributes Name of the archive member. Time of last modification in seconds since the epoch , as in os.stat_result.st_mtime. Permission bits, as for os.chmod. File type. type is usually one of these constants: REGTYPE, AREGTYPE, LNKTYPE, SYMTYPE, DIRTYPE, FIFOTYPE, CONTTYPE, CHRTYPE, BLKTYPE, GNUTYPE_SPARSE. To determine the type of a TarInfo object more conveniently, use the is() methods below. Name of the target file name, which is only present in TarInfo objects of type LNKTYPE and SYMTYPE. For symbolic links (SYMTYPE), the linkname is relative to the directory that contains the link. For hard links (LNKTYPE), the linkname is relative to the root of the archive. User ID of the user who originally stored this member. Group ID of the user who originally stored this member. The tar header starts here. The file's data starts here. Sparse member information. A dictionary containing key-value pairs of an associated pax extended header. … Attribution: Adapted from Python Documentation under PSF-2.0.
