problem with [[ -s /some/file ]] under 3.0.4

problem with [[ -s /some/file ]] under 3.0.4

[Timothy Luoma]

Hrm.... I just installed 3.0.4 and there seems to be a rather basic flaw:


/bin/rm -f /tmp/filezero
touch /tmp/filezero
ls -l = -rw-r--r--   1 luomat   wheel           0 Jul  1 18:16 /tmp/filezero


if [[ -s /tmp/filezero ]]                                                     
    then
	echo yes
else
	echo no
fi

result: yes

	###########################

Previously I was using 3.0.2 which worked fine:


/bin/rm -f /tmp/filezero
touch /tmp/filezero
	-rw-r--r--   1 luomat   wheel           0 Jul  1 18:16 /tmp/filezero


if [[ -s /tmp/filezero ]]                                                     
    then
	echo yes
else
	echo no
fi

result: no

Anyone else see this?

Nope:

user@machine:/ # echo $ZSH_VERSION
3.0.4
user@machine:/ # touch /tmp/hi
user@machine:/ # ls -l /tmp/hi
-rw-r--r--   1 user     user            0 Jul  1 17:30 /tmp/hi
user@machine:/ # if [[ -s /tmp/hi ]] ; then echo yes ; else echo no ; fi
no
user@machine:/ # ls -l /tmp/hi
-rw-r--r--   1 user     user            0 Jul  1 17:30 /tmp/hi

Well, either your compiler must be doing something really strange since
!!0 == 0  for most people, or you've done something strange elsewhere,
or your stat routines don't work.

% rm whatever
% touch whatever
% [[ -s whatever]] && echo yes || echo no
no

Well I had built it 4fat under NEXTSTEP using the stock cc (as I had done
before).  It gave me a lot of error 'warnings' but none fatal.

I rebuilt it using gcc and it works.

hrm.

Some day perhaps I'll try again, but not for awhile I think....

I'm not able to reproduce this.
