[Pkg-zsh-devel] Bug#1035679: zsh: can misprocess continue in a loop

Package: zsh
Version: 5.9-4+b1
Severity: normal
Tags: patch
If a continue occurs in an && chain inside a loop, the continue is not
effective. For example, if you save the following as foo.sh:
----
msg=unset
for x in 1 2 3 4 5; do
continue && msg=set && print Not executed
print Not executed, neither.
done
echo $msg
----
The output should be "unset", but zsh prints "set":
----
$ bash foo.sh
unset
$ dash foo.sh
unset
$ zsh foo.sh
set
----
This breaks the Git testsuite under zsh's sh mode, which was formerly
passing.
There's a patch upstream at
https://github.com/zsh-users/zsh/commit/12e5db145b098a62ff11b88eea26f473ea2ecdcf.
It would be great if this could be backported to zsh in Debian, since
the release cycle tends to be long and it prevents the shell from being
effectively used as a POSIX sh.
