set -e in bash 4

[Tobias Poschwatta]

In the following test case test1.sh, bash 4 behaves differently from
bash 3.1. The behaviour of bash 3.1 is what I would expect to be
correct.  Is this a bug in bash 4 or an intentional change?

Using bash 4:

$ /bin/bash --version
GNU bash, version 4.0.28(1)-release (x86_64-pc-linux-gnu)
Copyright (C) 2009 Free Software Foundation, Inc.
License GPLv3+: GNU GPL version 3 or later <http://gnu.org/licenses/gpl.html>

$ ls
test1a.sh  test1.sh  test2.sh
$ cat test1.sh 
( set -e; . ./test2.sh ) || exit 1
echo done
$ cat test2.sh 
echo 1
false
echo 2

$ cat test1a.sh 
( set -e; . ./test2.sh )
echo done
$ /bin/bash test1.sh 
1
2
done
$ /bin/bash test1a.sh 
1
done


Using bash 3.1.17:

$ /bin/bash --version
GNU bash, version 3.1.17(2)-release (i486-slackware-linux-gnu)
Copyright (C) 2005 Free Software Foundation, Inc.
$ /bin/bash test1.sh 
1
$ /bin/bash test1a.sh 
1
done


Thanks,
Tobias
