Description Pavel Raiskup 2012-03-02 09:31:01 UTC
Subject:  Tar --keep-old-files option does not work as expected.

Description of problem:

Tar traditional functionality of --keep-old-files option was (when extracting
archive contents) fail when extracted files already existed in file system
(actually return error code 2) even if is extracted everything that is
possible.

Tar is actually not returning error code when this problem occurs, it just
silently skips these files and continues with unpacking (returning zero).

This regression was pushed by 8f390db9 upstream commit and as a solution in
upstream for this problem was introduced new option "--skip-old-files", which
silently skips already existing files and "--keep-old-files" was switched back
to traditional behaviour (btw. the same like in RHEL-5) to failing when
extracted files already existed.

Version-Release number:

    tar-1.23.el6

Steps to Reproduce:

    1. go to clean directory
    2. tar -xf /some/archive.tar
    3. tar --keep-old-files -xf /some/archive.tar

Actual results:

    tar successes with zero return value without any warnings

Expeected results:

    tar should return error value 2 and tell something
