Description Elio Maldonado Batiz 2014-05-10 22:15:38 UTC

Description of problem: Use of xmlto produces bad formattiong on some of the nss certutil command line options on the man page.

As reported by Hubert Kario 2014-04-28 12:36:37 EDT on Bug 606022

... errors in certutil man page: I used nss-tools-3.15.3-11.el6.x86_64

 -e argument is formatted as if it was an option for -d argument

 same for:
 -u and -t
 -6 and -5
 -7 and -6


Version-Release number of selected component: xmlto-0.0.23-3.el6.i686 


How reproducible: always

Steps to Reproduce: 
1. execute man certutil

Actual results:
-e argument formatted as if it was an option for -d argument (extra indentation) and similarly with -u and -t, -6 and -5 and -7 and -6


Expected results:
-e argument formatted at the same level as -d argument and the should happen  for -u and -t, -6 and -5, and -7 and -6. 


Additional info:

It works fine on rhel-7.0 and fedora. In all the man pages are generated from docbook xml using xmlto.

Running $ rpm -q xmlto shows me:
rhel-6.6:  xmlto-0.0.23-3.el6.i686    -- bad results
rhel-7.0:  xmlto-0.0.25-7.el7.x86_64  -- good results

Problem seems to be caused by the older version of xmlto we have on rhel-6.6.

Comment 2 Ondrej Vasik 2014-05-11 14:01:54 UTC

Thanks for report, next time it would be good to attach the failing xml, so I can more easily analyze it. I checked out the nss sources, and managed to reproduce it. However, you are wrong with the analysis the issue is caused by xmlto - actually, xmlto is innocent here - docbook-style-xsl is causing the issues.
I haven't analyzed deeper what exactly is the issue, though - it seems like some issue with itemized lists. I'm not sure docbook-style-xsl will get updated in RHEL-6 anytime soon (there are other bugs causing doc build issues, proposed for fastracks, but it still slips through releases). For now, I would suggest to patch the generated man-pages...

Comment 3 Ondrej Vasik 2014-05-11 14:14:48 UTC

note to myself, confirmed that using manpages/lists.xsl from 1.78.1 docbook xsl stylesheets package fixes the issue. There are just 4 small changes in this file, seems like an easyfix.

Comment 4 Ondrej Vasik 2014-05-11 14:27:37 UTC

Difference of the generated man-pages is in:
236c236
< .sp
---
> .RS 4

Final listitem has to have .sp (add new line) instead of .RS 4 (relative indentation by 4) to finalize the bullet.

Thank Ondrej you for the prompt response. I confirm that the 4 small changes do indeed work, see https://bugzilla.redhat.com/show_bug.cgi?id=606022#c51.

Comment 9 Ondrej Vasik 2017-03-27 07:08:13 UTC

I'm going to WONTFIX the issue for RHEL 6. Although fix is easy and known(and issue is fixed in RHEL 7), it is only useful for building new packages, workaround exists and with RHEL 6 in production phase 3, I don't think it makes sense to do an update for this.
