Lars Gustäbel 7cc9c8bbe1 Issue #1531: Read fileobj from the current offset, do not seek to 
the start.

(backport from r59260)
 2007-12-01 21:06:06 +00:00
Lars Gustäbel a9bad98e3d 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 8ff1f6a69e Bug #1704156: Support for unicode strings as input filenames is 
neither documented nor intended but works in Python 2.4 under certain
conditions. This stopped working in 2.5 because struct.pack is used.
This small patch restores the old behaviour. A more solid solution is
planned for 2.6.

Fix bug #1543303, tarfile adds padding that breaks gunzip.

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.

Georg Brandl 38c6a22f38 Patch #1484695: Update the tarfile module to version 0.8. This fixes 
a couple of issues, notably handling of long file names using the
GNU LONGNAME extension.

Neal Norwitz f339654280 Patch #1338314, Bug #1336623: fix tarfile so it can extract

Will backport.

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.

Andrew M. Kuchling 864bba1981 [Patch 988444] 
Read multiple special headers
- fixed/improved handling of extended/special headers
in read-mode (adding new extended headers should be
less painful now).
- improved nts() function.
- removed TarFile.chunks datastructure which is not
(and was never) needed.
- fixed TarInfo.tobuf(), fields could overflow with too
large values, values are now clipped.

Andrew M. Kuchling 6e4f7a82da [Bug #812325 ] tarfile.close() can write out more bytes to the output

   to ensure that any full blocks are written out.

Tim Peters f9347782e0 Somebody must not have run the test before checking this in -- it had
