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 Eduardo Minguez 2013-07-26 08:24:15 UTC 
Description of problem:
gzip "--rsyncable" option is not documented in the man, but appears in the "-h" included help (and should be in the code itself)

Version-Release number of selected component (if applicable):
gzip-1.3.12-18.el6.x86_64 (but I think it's never included, so it maybe applies to gzip-*)

How reproducible:
Find "rsyncable" in man pages of gzip

Steps to Reproduce:
1. install gzip
2. man gzip
3. search for rsyncable

Actual results:
No "rsyncable" found

Expected results:
rsyncable flag explanation

Additional info:
Comment 2 RHEL Program Management 2013-10-13 23:20:18 UTC 
This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated
in the current release, Red Hat is unable to address this
request at this time.

Red Hat invites you to ask your support representative to
propose this request, if appropriate, in the next release of
Red Hat Enterprise Linux.
Comment 3 Jan Chaloupka 2014-06-05 07:56:20 UTC 
After reading:

http://lists.gnu.org/archive/html/bug-gzip/2010-06/msg00002.html

and

http://beeznest.wordpress.com/2005/02/03/rsyncable-gzip/

this could be the solution:

--rsyncable
	Having a compressed file and synchronized between two computers using rsync, this option allows after changing a file not to sent an entire new archive but just a small portion of it. Normally, after a change in any file of an archive, compressing algorithm can generate completelly diffrent archive that differ from the old one. This causes rsync to transmit entirely new version to the remote computer. With this option, rsync is able to transmit just the changed portions (plus some minimal padding in the area of the archive that necessarily changed as a result of the changes in the file).

After grammar correction of course :)

What do you think, Petr, Eduardo? Is it sufficient explanation?
Comment 4 Eduardo Minguez 2014-06-05 08:03:02 UTC 
It's pretty explanatory for me.
Thanks!
Comment 5 Petr Stodulka 2014-06-05 08:22:56 UTC 
Yes, this could be the solution.

From upstream, --rsyncable is only RH/Fedora feature.
