Typo -- the relation is to bug 116779. It's fixed in tar-1.15.1. http://www.gnu.org/software/tar/tar.html#downloading Created attachment 109423 [details]
patch fix tar-1.14
I've tested the above patch, and it appears to correct the sparse file problem completely. As of Jan 25 2005 the available "tar" on a fully yum-updated system still apparently has this problem. How long does it take for this sort of fix to propagate into the repository as a new .rpm ? I'm getting a similar problem with an archive created on Red Hat 9: [root@ars predec2004]# tar -xvf rec00628bkup.tar tar: This does not look like a tar archive tar: Skipping to next header tar: Archive contains obsolescent base-64 headers tar: Read 1320 bytes from rec00628bkup.tar tar: Error exit delayed from previous errors |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041111 Firefox/1.0 Description of problem: When listing (-t) or extracting (-x) a subset of files in a tar archive, and a sparse file stored with the -S option is being skipped because it does not match the selection criteria, tar complains about an invalid sparse member in the archive and attempts to skip to the next header. Version-Release number of selected component (if applicable): tar-1.14-4 How reproducible: Always Steps to Reproduce: 1. echo hello | dd obs=1k seek=50 of=testfile 2. echo anything >file2 3. tar -cSf test.tar testfile file2 4. tar -tvf test.tar file2 Actual Results: tar: testfile: invalid sparse archive member tar: Skipping to next header -rw-r--r-- root/root 9 2005-01-02 16:49:13 file2 tar: Error exit delayed from previous errors Expected Results: -rw-r--r-- root/root 9 2005-01-02 16:49:13 file2 Additional info: "Skipping to next header" is inherently an uncertain operation which can fail badly if one of the archive members is itself a tar archive. This makes use of tar for backups risky if sparse files are involved. This is probably related to bug 11679. This version of tar (1.14-4) appears to behave properly if the sparse member is actually being listed or extracted from the archive.
