[Openstack-devel] Bug#726304: websockify: rebind.so not found by rebind

Package: websockify
Version: 0.5.1+dfsg1-2
Severity: normal

Dear Maintainer,

1. /usr/bin/rebind fails similar to Bug #719889, because the shared
library is not found by the shell wrapper.
2. usage is never printed; suppot for "--help" is still missing in my
version below.
3. It was never checked, if the required parameters were given
4. Missing quotes.
5. You should use "exec" to get rid of the intermediate shell process.
6. bash is overkill.
7. The name "rebind" is IMHO to generic: "websockify-rebind" perhaps?
8. Multi-arch-support is missing.
9. The only architecture dependent files are the two "rebind.*o" files.
Perhaps split them with the shell wrapper into their own package and
make the websockify package "Architecture: all"?


mydir="$(readlink -f "$(dirname "${0}")")"
[ -e "${mylib}" ] || { echo "${mylib} not found" >&2; exit 1; }

usage () {
    echo "Usage: $(basename "$0") OLD_PORT NEW_PORT COMMAND_LINE"
    echo "Launch COMMAND_LINE, but intercept system calls to bind"
    echo "to OLD_PORT and instead bind them to localhost:NEW_PORT"
    exit 2
[ $# -ge 3 ] || usage

# Parameter defaults

export REBIND_PORT_OLD="${1}"
export REBIND_PORT_NEW="${2}"
shift 2

LD_PRELOAD="${mylib}" exec "${@}"
