patch 9.0.1955: Vim9: lockvar issues with objects/classes Commit: https://github.com/vim/vim/commit/ee865f37acab6cac2cee6a171d60e1b365f852b0 Author: Ernie Rael <errael@raelity.com> Date: Fri Sep 29 19:53:55 2023 +0200 patch 9.0.1955: Vim9: lockvar issues with objects/classes Problem: Vim9: lockvar issues with objects/classes Solution: fix `get_lhs()` object/class access and avoid `SEGV`, make error messages more accurate. - `get_lval()` detects/returns object/class access - `compile_lock_unlock()` generate code for bare static and obj_arg access - `do_lock_var()` check lval for `ll_object`/`ll_class` and fail if so. Details: - Add `ll_object`/`ll_class`/`ll_oi` to `lval_T`. - Add `lockunlock_T` to `isn_T` for `is_arg` to specify handling of `lval_root` in `get_lval()`. - In `get_lval()`, fill in `ll_object`/`ll_class`/`ll_oi` as needed; when no `[idx] or .key`, check lval_root on the way out. - In `do_lock_var()` check for `ll_object`/`ll_class`; also bullet proof ll_dict case and give `Dictionay required` if problem. (not needed to avoid lockvar crash anymore) - In `compile_lock_unlock()` compile for the class variable and func arg cases. closes: #13174 Signed-off-by: Christian Brabandt <cb@256bit.org> Co-authored-by: Ernie Rael <errael@raelity.com>
