Hi,
As reported in bin/146189, script(1) was returning the wrong exit status
sometimes.
The PR says that script(1) was broken by r205008/r205635, neither of
which are in 7-stable or releng/7.4. Yet it is broken on 7.4.
This is easily seen on 7.4:
# script -q /dev/null false; echo $?
1
# script -q /dev/null false; echo $?
1
# script -q /dev/null false; echo $?
0
# script -q /dev/null false; echo $?
1
# while true; do script -q /dev/null false && echo $? && break; echo
$?; done

r207453 was MFC'd to 8-stable at the time, but not 7-stable, likely due
to the changes attributed to causing the issue not having been on 7-stable.
I am not entirely sure *how* script(1) broke on 7.4, but I have tested
r207453 on 7.4 and found that it Works For Me.
FWIW, could someone please MFC this to 7-stable?
The reason I ran into this is I am maintaining portupgrade, and working
on ports/147242 and ports/131111. Both of which seem to be due to
script(1) returning the wrong exit status.
7.x is EoL Feb 2013 [1]. Given that, and that script(1)'s return code
cannot be relied on for automated scripts. I am wondering what the
thoughts are on putting this patch out as an errata?
Regards,
Bryan Drewery
