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.

Comment 1 Andy Grover 2012-01-23 18:44:19 UTC 
permissions on /usr/libexec/mercurial and /usr/libexec/mercurial/hgk need to be +x.
Comment 4 Suzanne Logcher 2012-02-14 23:28:53 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 unfortunately unable to
address this request at this time. Red Hat invites you to
ask your support representative to propose this request, if
appropriate and relevant, in the next release of Red Hat
Enterprise Linux. If you would like it considered as an
exception in the current release, please ask your support
representative.

Fix permissions of hgk

This patch fixes the issue in this bugzilla, so can it please be applied and an updated version of mercurial be released?
Comment 6 Bob Arendt 2014-11-05 18:45:09 UTC 
The problem is obvious from listing the the rpm contents:

rpm -qlvp mercurial-hgk-1.4-3.el6.x86_64.rpm
-rw-r--r--    1 root    root                      118 Mar 12  2010 /etc/mercurial/hgrc.d/hgk.rc
-rw-r--r--    1 root    root                    11698 Nov 16  2009 /usr/lib64/python2.6/site-packages/hgext/hgk.py
-rw-r--r--    1 root    root                    10826 Mar 12  2010 /usr/lib64/python2.6/site-packages/hgext/hgk.pyc
-rw-r--r--    1 root    root                    10780 Mar 12  2010 /usr/lib64/python2.6/site-packages/hgext/hgk.pyo
drw-r--r--    2 root    root                        0 Mar 12  2010 /usr/libexec/mercurial
-rw-r--r--    1 root    root                   109044 Mar 12  2010 /usr/libexec/mercurial/hgk

A directory that doesn't have execute permission can't function as a directory.

I've tested Dave's patch and it works. The issue is an obvious error in the mercurial packaging, not the code itself.  Please fix and re-release the package.
Comment 7 Petr Stodulka 2014-11-07 09:41:04 UTC 
I agree. It seems like candidate for fasttrack.
Comment 8 Dave Johansen 2015-04-30 21:44:23 UTC 
Any update on this being applied?
Comment 9 Petr Stodulka 2015-05-03 21:19:54 UTC 
Hi Dave, I hope that patch will be aplied in rhel-6.8.
Comment 10 Andrew John Hughes 2015-05-13 17:00:54 UTC 
Just hit this myself today. Given this has PM+dev ACKs, it could go out for RHEL 6.7 with the requisite QA ack added.

At present, hg view is completely broken as shipped.
Comment 11 Andrew John Hughes 2015-05-13 17:11:33 UTC 
The test and fix is very simple.

1. $ hg clone http://hg.openjdk.java.net/jdk8u/jdk8u
2. $ cd jdk8u
3. $ hg view

Current result:

/bin/sh: /usr/libexec/mercurial/hgk: Permission denied

Expected result:

hgk loads up, displaying a graphical view of the repository.

Fix:

Making /usr/libexec/mercurial and /usr/libexec/mercurial/hgk
executable. I tested this fix manually by doing the following as
root:

$ chmod ugo+X /usr/libexec/mercurial
$ chmod ugo+x /usr/libexec/mercurial/hgk

and hgk then loads.
Comment 12 Petr Stodulka 2015-05-13 17:13:10 UTC 
Yes, it's expected solution according to proposed patch :-)
Comment 13 Andrew John Hughes 2015-05-13 17:30:32 UTC 
Was the patch sufficient? I found that it only worked if hgk itself was also made executable.
Comment 14 Petr Stodulka 2015-05-13 17:49:18 UTC 
Yes, it is. Because hgk inherit permissions from directory.
Comment 15 Andrew John Hughes 2015-05-13 18:02:55 UTC 
Ok, so the RPM change also makes hgk executable? That's fine.
Comment 16 Bob Arendt 2015-05-13 18:03:54 UTC 
The patch works - we've been rebuilding/installing a patched mercurial rpm for over 3 years now.  It would be great if Redhat would correct their packaging error and release an update.
Comment 19 Leos Pol 2015-05-19 07:45:41 UTC 
# rpm -q mercurial

# rpm -q mercurial
