In the latest release (courier-0.45.2.20040325.tar.bz2), this still has
the same problem. The following appears in courier/configure{.in}, but
it still doesn't address the issue I raised in my earlier message:
if $SHELL -c 'ulimit -v 2>/dev/null'
then
ULIMIT='ulimit -v'
else
ULIMIT='ulimit -d'
fi
On my system, "ulimit -v" works, but "ulimit -v ARGUMENT" _doesn't_
work. This is the case that I originally wrote about. For example:
% ulimit -v
589824
% ulimit -v 589824
bash: ulimit: virtual memory: cannot modify limit: Invalid argument
In all of the courier startup scripts, "ulimit -d/-v" is used _with_ an
argument. Hence, the test in the 45.2.20040325 release still does not
cover that case. The test we need is this:
if $SHELL -c 'ulimit -v 0 2>/dev/null'
then
ULIMIT='ulimit -v'
else
ULIMIT='ulimit -d'
fi
Note the numeric argument after the '-v' in the 'if' line. I chose
zero, but this could be any other reasonable number. The reason that
this has to be done via "$SHELL -c" is so that the "ulimit" call doesn't
alter the resource limits of the shell that is running the
courier/configure script itself.
