# Using tar 1.15.x the following equivalent command sets:
|
|
#
|
|
# 1. tar cf archive file1 file2
|
|
# and
|
|
# 2. tar cfT archive /dev/null
|
|
# tar rf archive file1
|
|
# tar rt archive file2
|
|
#
|
|
# produced different archives (GNU format is assumed). It was reported
|
|
# by TAMUKI Shoichi on 2006-07-21 [1].
|
|
#
|
|
# The bug was due to tar being unable to discern between GNU and OLDGNU
|
|
# formats and always assuming the latter. The main difference between
|
|
# the two is that OLDGNU preserves all bits in the mode field, whereas
|
|
# GNU format keeps only the lower 9 ones (mode & 0777).
|
|
#
|
|
# This was fixed on 2006-07-24 (commit f4e4adea80a) by making tar truncate
|
|
# the mode field even in OLDGNU format. Obviously, the fix broke the
|
|
# format backward compatibility, but it went unnoticed until 2009-10-03
|
|
# (after all, the OLDGNU format is not in much use nowadays), when
|
|
# Igor Zhbanov reported it [2].
|
|
#
|
|
# The final fix was applied on 2009-10-04.
