Gregory P. Smith 88440960f9 A stab in the dark attempt to fix the alpha/tru64 buildbot problem and add more
test coverage of valid inputs to zlib.crc32.

Lars Gustäbel 0192e43d64 Issue #2004: Use mode 0700 for temporary directories and default
permissions for missing directories.

(will backport to 2.5)

Lars Gustäbel 77b2d63b40 Issue #1531: Read fileobj from the current offset, do not seek to
the start.

Lars Gustäbel 0f4a14b56f TarFile.__init__() no longer fails if no name argument is passed and
the fileobj argument has no usable name attribute (e.g. StringIO).

Lars Gustäbel 104490e615 Added exclude keyword argument to the TarFile.add() method. 2007-06-18 11:42:11 +00:00
Lars Gustäbel a0fcb9384e Added errors argument to TarFile class that allows the user to
specify an error handling scheme for character conversion. Additional
scheme "utf-8" in read mode. Unicode input filenames are now
supported by design. The values of the pax_headers dictionary are now
limited to unicode objects.

Fixed: The prefix field is no longer used in PAX_FORMAT (in
conformance with POSIX).
Fixed: In read mode use a possible pax header size field.
Fixed: Strip trailing slashes from pax header name values.
Fixed: Give values in user-specified pax_headers precedence when
writing.

Added unicode tests. Added pax/regtype4 member to testtar.tar all
possible number fields in a pax header.

Added two chapters to the documentation about the different formats
tarfile.py supports and how unicode issues are handled.

Brett Cannon 6cef076ba5 Remove direct call's to file's constructor and replace them with calls to
open() as ths is considered best practice.

Lars Gustäbel c64e40215d This is the implementation of POSIX.1-2001 (pax) format read/write
support.

The TarInfo class now contains all necessary logic to process and
create tar header data which has been moved there from the TarFile
class. The fromtarfile() method was added. The new path and linkpath
properties are aliases for the name and linkname attributes in
correspondence to the pax naming scheme.

The TarFile constructor and classmethods now accept a number of
keyword arguments which could only be set as attributes before (e.g.
dereference, ignore_zeros). The encoding and pax_headers arguments
were added for pax support. There is a new tarinfo keyword argument
that allows using subclassed TarInfo objects in TarFile.

The boolean TarFile.posix attribute is deprecated, because now three
tar formats are supported. Instead, the desired format for writing is
specified using the constants USTAR_FORMAT, GNU_FORMAT and PAX_FORMAT
as the format keyword argument. This change affects TarInfo.tobuf()
as well.

The test suite has been heavily reorganized and partially rewritten.
A new testtar.tar was added that contains sample data in many formats
from 4 different tar programs.

Some bugs and quirks that also have been fixed:
Directory names do no longer have a trailing slash in TarInfo.name or
TarFile.getnames().
Adding the same file twice does not create a hardlink file member.
The TarFile constructor does no longer need a name argument.
The TarFile._mode attribute was renamed to mode and contains either
'r', 'w' or 'a'.

Tim Peters a05f6e244a _Stream.close(): Try to kill struct.pack() warnings when
writing the crc to file on the "PPC64 Debian trunk" buildbot
when running test_tarfile.

This is again a case where the native zlib crc is an unsigned
32-bit int, but the Python wrapper implicitly casts it to
signed C long, so that "the sign bit looks different" on
different platforms.

Neal Norwitz 4a5fbda66d Part of SF patch #1484695. This removes dead code. The chksum was
already verified in .frombuf() on the lines above.  If there was
a problem an exception is raised, so there was no way this condition
could have been true.

Neal Norwitz b0e32e2b71 Fix SF bug # 1330039, patch # 1331635 from Lars Gustaebel (tarfile maintainer)
Problem: if two files are assigned the same inode
number by the filesystem, the second one will be added
as a hardlink to the first, which means that the
content will be lost.

The patched code checks if the file's st_nlink is
greater 1. So only for files that actually have several
links pointing to them hardlinks will be created, which
is what GNU tar does.

Will backport.
