Description Pavel Raiskup 2014-08-13 13:43:09 UTC

+++ This bug was initially created as a clone of Bug #1123854 +++

IIRC upstream tcsh's git-log, from tcsh 6.17.06, the $anyerror variable works
that way:

    $ echo $?anyerror
    1
    $ false | true ; echo $?
    1
    $ set anyerror ; false | true ; echo $?
    1
    $ unset anyerror ; false | true ; echo $?
    0

From tcsh617.el5 we introduced (yet?) upstream-incompatible
'$tcsh_posix_status' variable, which has opposite meaning.  For compatibility
with older RHEL and upstram, we need to support both 'anyerror' and
'tcsh_posix_status'.  Currently, 'anyerror' variable is not working in RHEL7;
where is tcsh-6.18.00.

This bug exists to re-introduce $anyerror variable.

--- Additional comment from Pavel Raiskup on 2014-08-13 15:41:13 CEST ---

JFTR, upstream is not interested in $tcsh_posix_status support:

Also, upstream has now clear documentation how $anyerror works:

Fix is in original bugreport.

Comment 1 Pavel Raiskup 2014-08-27 15:11:00 UTC

Fix including testcase for tcsh_posix_status pushed to Fedora (reusable in
RHEL):

Comment 2 Pavel Raiskup 2014-08-27 15:14:14 UTC

Ignore comment #1 please -- I thought this bug is filed against RHEL7.
This should be fixed in f21+.
