12.5.2 TarInfo Objects


12.5.2 TarInfo Objects

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 getmember(), getmembers() and gettarinfo().

class TarInfo( [name])
Create a TarInfo object.

frombuf( )
Create and return a TarInfo object from a string buffer.

tobuf( posix)
Create a string buffer from a TarInfo object. See TarFile's posix attribute for information on the posix argument. It defaults to False.

New in version 2.5: The posix parameter.

A TarInfo object has the following public data attributes:

name
Name of the archive member.

size
Size in bytes.

mtime
Time of last modification.

mode
Permission bits.

type
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.

linkname
Name of the target file name, which is only present in TarInfo objects of type LNKTYPE and SYMTYPE.

uid
User ID of the user who originally stored this member.

gid
Group ID of the user who originally stored this member.

uname
User name.

gname
Group name.

A TarInfo object also provides some convenient query methods:

isfile( )
Return True if the Tarinfo object is a regular file.

isreg( )
Same as isfile().

isdir( )
Return True if it is a directory.

issym( )
Return True if it is a symbolic link.

islnk( )
Return True if it is a hard link.

ischr( )
Return True if it is a character device.

isblk( )
Return True if it is a block device.

isfifo( )
Return True if it is a FIFO.

isdev( )
Return True if it is one of character device, block device or FIFO.
