There was no check for the -B/braceexpand option before calling path_expand() to process brace expansion, making it impossible to turn off brace expansion within command substitutions. Normally the lexer flags brace expansion so that this code is not reached, but shell code within command substitutions is handled differently. Red Hat patches this by adding this check to the function itself: https://src.fedoraproject.org/rpms/ksh/blob/642af4d6/f/ksh-20140301-fikspand.patch But I think it's more logical to patch it at the point of decision. src/cmd/ksh93/sh/macro.c: endfield(): - Decide to call either path_generate() or path_expand() based on the state of the SH_BRACEEXPAND shell option. - Fix '#if SHOPT_BRACEPAT' preprocessor check that previously hardcoded this decision at compile time. src/cmd/ksh93/tests/options.sh: - Add tests. |
