Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description bfan 2013-06-09 08:39:20 UTC 
Description of problem:
txz-in unpack the tarball,which is packed by txz-out, failed.
though it is marked as "deprecated" in its help output, it is still provided.  


Version-Release number of selected component (if applicable):
libguestfs-1.20.8-4.el6.x86_64

How reproducible:
100%


Steps to Reproduce:
# guestfish -N fs -m /dev/sda1

Welcome to guestfish, the guest filesystem shell for
editing virtual machine filesystems and disk images.

Type: 'help' for help on commands
      'man' to read the manual
      'quit' to quit the shell

><fs> mkdir /test
><fs> touch /test/1.txt
><fs> txz-out /test test.txz.out
><fs> !ls -l test.txz.out
-rw-r--r--. 1 root root 136 Jun  9 13:59 test.txz.out
><fs> mkdir /new
><fs> txz-in test.txz.out /new
libguestfs: error: txz_in: tar subcommand failed on directory: /new: xz: (stdin): File format not recognized
tar: Child returned status 1
tar: Error is not recoverable: exiting now
><fs>


Actual results:
txz_in failed

Expected results:
txz_in unpack tarball well

Additional info:
It works in libguestfs-1.16.34-2.el6.x86_64, regression
Comment 2 Richard W.M. Jones 2013-06-10 14:55:56 UTC 
Simple reproducer:

$ guestfish -N fs -m /dev/sda1 mkdir /test : touch /test/1.txt : txz-out /test test.txz
$ file test.txz
test.txz.out: bzip2 compressed data, block size = 900k

(Note that the type of 'test.txz' should not be bzip2-compressed.
It should be xz-compressed)

This bug also occurs upstream, so I'm cloning this for upstream.
