Didier,
Could you get this posted to the enlightenment-devel list? The csh/tcsh
login bug has popped up again after the rasterman pushed for code
cleanup in entrance (see
http://sourceforge.net/mailarchive/forum.php?thread_id=30631844&forum_id=6427
) for details.
I'd like for the bug to get fixed again.
Thanks!
Greg

Please note that in the recent code cleanup of entrance, you are no
longer allowing people (again) to login to enlightenment from either csh
or tcsh shells. The reason why the code was kind of cludgy was to get
around this problem---see the recent exchange between Phuah and myself
concerning this. The bug was originally fixed around August, but crept
back into entrance a couple of weeks ago.
Could someone please submit the following patch and commit it to cvs for
entrance?
Thanks!
Greg

Hi Greg,
I seems to have problems committing to the entrance cvs, so I have
attached a cvs diff here for you to try and commit it.
Cheers,

Phuah,
It looks like your highlight of the problem has not been folded into the
most recent commits of entrance yet. Is it possible for you to bump
this back up?
I have confirmed, once again, that it is indeed tcsh/csh causing the
problem.
Thanks!
Greg

The latest entrance commit makes it incompatible with tcsh.
I am reproducing the mail I sent to the list below:
-------------------
Hi,
Sorry that this came in late. The latest entrance patch have some problems
---------------------
revision 1.86
date: 2006/08/31 14:37:37; author: essiene; state: Exp; lines: +73 -24
- Commit Entrance shell utilization patches from Eugen Minciu... they
work like a charm :)
- Update TODO
---------------------
There IS a reason for using /bin/sh and not the user's shell, and that
explains the mess at that part of the code. Check the following commit.
---------------------
revision 1.80
date: 2005/12/10 05:55:09; author: xcomputerman; state: Exp; lines: +1 -1
I thought I had committed this...
Force usage of /bin/sh to execute session to avoid problems with csh users.
---------------------
The exact Reason can be seen from the tcsh man page
----------------
-l The shell is a login shell. Applicable only if -l is the only
flag specified.
----------------
So there you go, you can't do csh -l -c xxx, it won't work, and the
latest commit will give problems to users with their default shell set
to csh.
Cheers,
