Description Sebastien BLAISOT 2005-09-28 09:57:24 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.10) Gecko/20050909 Fedora/1.0.6-1.2.fc3 Firefox/1.0.6

Description of problem:
ksh-20040229-8 rpm in RHEL3 ES extra channel obsoletes pdksh. But it contains regressions on pdksh, such as -e option to the echo command.

thus, this package should not have obsoleted pdksh which is in the base channel

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.install rhel3 U4
2. subscribe to channel base and extra
3. up2date -u

Actual Results:  ksh replace pdksh

Expected Results:  pdksh still default ksh implementation

Additional info:

up2date -u pdksh returns to old implementation, but next up2date -u will put back ksh
Comment 1 Sebastien BLAISOT 2005-09-28 09:58:19 EDT
oups, i meant up2date -i pdksh (install, not upgrade) returns to the old
implementation until next up2date -u
Comment 2 Karsten Hopp 2005-10-04 08:27:26 EDT
ksh needs to obsolete pdksh as both packages provide /bin/ksh.  
AT&T's ksh is the 'real' ksh and pdksh is just a clone, so I'm not sure how ksh
can have regressions from pdksh. pdksh just behaves differently as it isn't 100%
compatible with the original.

If you've encountered any errors with the latest Red Hat provided packages of
AT&T's ksh (ksh-20050202-0.3E.1), please report them to gsf@research.att.com,
that's the feedback adress mentioned at http://www.research.att.com/sw/download/
(As we keep our package close to the upstream sources with just one minor patch
to make it buildable on ppc64, feedback should go upstream).
Comment 3 Karsten Hopp 2005-10-11 09:12:25 EDT
btw: an easy workaround to the echo -e problem is to use the systems echo command
by disabling ksh's builtin echo: 'builtin -d echo'
Comment 4 Sebastien BLAISOT 2005-10-11 09:21:26 EDT
there is a lot of workaround for this particular problem :
- remove machine from extra channel
- do not update the system
- use bash
- call /bin/echo instead of just echo
- use printf instead of echo
- do not echo (looks like "the chicken doesn't need to cross the road")

the fact is that each workaround needs us to modify a whole set of production
scripts which is not an easy task.

this worked before and just doesn't work anymore. this looks like a regression
for the end customer.
