src/cmd/ksh93/sh/args.c: sh_argopts():
- Remove special-casing for --posix (see also data/builtins.c) and
move the case -5: to the case ':' instead, so this option is
handled like all other long options. This change fixes two bugs:
1. 'set --posix' had no effect on the letoctal or braceexpand
options. Reproducer:
$ set --posix
$ [[ -o braceexpand ]]; echo $?
0
$ [[ -o letoctal ]]; echo $?
1
2. 'ksh --posix' could not run scripts correctly because it
wrongly enabled '-c'. Reproducer:
$ ksh --posix < <(echo 'exit 0')
ksh: -c requires argument
Usage: ksh [--posix] [arg ...]
Help: ksh [ --help | --man ] 2>&1
- Don't allow 'set --default' to unset the restricted option.
src/cmd/ksh93/tests/options.sh:
- Add regression tests for the bugs described above, using -o posix
and --posix.
src/cmd/ksh93/tests/restricted.sh:
- Add a regression test for 'set --default' in rksh.
