On my Gentoo box I'm trying to extract an archive I've just created under FreeBSD on another host. There are files and dirs with permissions set to 000. Tar fails to extract some of these files, because it can not get access to directories created by itself. I've noticed some directories were created with correct permissions 000 and there were files. "Permission denied" message appears when there are complex directory structure. Here is the bash script I used to test the bug (must be run as root): ===================== chess# uname -a FreeBSD chess.z8.ru 6.0-RELEASE FreeBSD 6.0-RELEASE #0: Thu Nov 3 09:36:13 UTC 2005 root@x64.samsco.home:/usr/obj/usr/src/sys/GENERIC i386 chess# cat makebug.sh #!/bin/sh mkdir -p dir1/dir2/dir3/dir4 mkdir -p dir1/dir2/dir3/dir4-1 echo test4_1 > dir1/dir2/dir3/dir4/test4_1 echo test > dir1/dir2/dir3/dir4/test4_2 echo test > dir1/dir2/dir3/dir4/test4_3 echo test > dir1/dir2/dir3/dir4-1/test4-1_1 echo test > dir1/dir2/dir3/dir4-1/test4-1_2 echo test > dir1/dir2/dir3/dir4-1/test4-1_3 chmod -R 000 dir1/dir2/dir3/dir4 chmod -R 000 dir1/dir2/dir3/dir4-1 tar -jcvf tarbug.tbz dir1 rm -rf dir1 mv tarbug.tbz ~subadm/ ; chown subadm ~subadm/tarbug.tbz ============================== Then I scp this .tbz to my host and untar it. Tar exits with error messages. ============================== cronfy@cronfy ~ $ uname -a Linux cronfy 2.6.17-gentoo-r4cronfy #7 SMP Thu Aug 3 11:30:09 MSD 2006 i686 Intel(R) Celeron(R) CPU 2.40GHz GenuineIntel GNU/Linux cronfy@cronfy ~ $ scp subadm@chess.z8.ru:tarbug.tbz ./ cronfy@cronfy ~ $ tar jxvf tarbug.tbz dir1 dir1/dir2 dir1/dir2/dir3 dir1/dir2/dir3/dir4 dir1/dir2/dir3/dir4-1 dir1/dir2/dir3/dir4-1/test4-1_1 dir1/dir2/dir3/dir4-1/test4-1_2 dir1/dir2/dir3/dir4-1/test4-1_3 dir1/dir2/dir3/dir4/test4_1 tar: dir1/dir2/dir3/dir4/test4_1: Cannot open: Permission denied dir1/dir2/dir3/dir4/test4_2 tar: dir1/dir2/dir3/dir4/test4_2: Cannot open: Permission denied dir1/dir2/dir3/dir4/test4_3 tar: dir1/dir2/dir3/dir4/test4_3: Cannot open: Permission denied tar: Error exit delayed from previous errors ========================== I tried to run this script on Gentoo, but an archive created by it is extracted just fine after. Also there is no errors if there is no 'dir4-1' directory.
*** This bug has been marked as a duplicate of 141197 ***
Are you sure this bug is a duplicate for 141197? Look: BUG 141197 says tar extracts files WITH WRONG PERMISSIONS. THIS BUG says tar extracts files WITH CORRECT PERMISSIONS (perms were set by my with `chmod -R 000 dir1`), but tar sets these perms too early so it can not continue an extraction due lack of permissions. Looks like tar 1. extracts everything (as it thinks) from dir4 1.1 sets perms on dir4 2. extracts everything from dir4-1 2.2 sets perms on dir4-1 3. and NOW it suddenly finds out there are still unextracted content for dir4, but perms were already set at step 1.1 - tar can't write anything to this directory.

Created attachment 93830 [details] Example of buggy tar archive This is the archive I created with makebug.sh on my FreeBSD system. I could not extract all it's files on my Gentoo box.
upstream answer: Run tar with --delay-directory-restore option in this case.
tar does not know anything about this option: cronfy@cronfy ~/tmp $ tar -jxvf tarbug.tbz --delay-directory-restore tar: unrecognized option `--delay-directory-restore' Try `tar --help' or `tar --usage' for more information.
it's in tar-1.15.9x+
