Neal Norwitz 7443b80549 Backport 51432: 
Fix bug #1543303, tarfile adds padding that breaks gunzip.
Patch # 1543897.  (remove the padding)

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

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 
than are specified by the buffer size.  The patch calls .__write()
   to ensure that any full blocks are written out.

Andrew M. Kuchling 10a444965d [Bug #822668] tarfile raises an exception if the tarfile is gzipped and is too large; the gzip filesize should be written out mod 2**32. (Reported by Johan Fredrik Ohman) 2003-10-24 17:38:34 +00:00
Jack Jansen 2b4b5a54d6 Fix by Lars Gustaebel for bug 721871: don't get upset if the prefix

Neal Norwitz 4ec6824896 Fix test_tarfile failure when gzip is not available 
The module would exist, but be empty if already imported.
This change ensures we have gzip available.

Tim Peters f9347782e0 Somebody must not have run the test before checking this in -- it had 
a fatal tab/space inconsistency under -tt.

Jack Jansen cfc4902b2a Make tarfile raise ImportError on MacOS9. The pathname handling needs work, and I don't have time to fix it. I'll file a bug report. 2003-03-07 13:37:32 +00:00
Jack Jansen 834eff6a4c Test that os.utime and os.chmod actually exist before using them. 2003-03-07 12:47:06 +00:00
Andrew MacIntyre 7970d20792 OS/2 has no concept of file ownership, like DOS & MS Windows version 
prior to NT.  EMX has a number of Posix emulation routines, including
geteuid() but lacks chown(), so silently skip trying to actually set
a file ownership when extracting a file from a tar archive.
