runtime(dist): centralize safe executable check and add vim library (#13413) Commit: https://github.com/vim/vim/commit/cd8a3eaf5348feacfecab4b374b7ea4ce6a97422 Author: D. Ben Knoble <ben.knoble+github@gmail.com> Date: Sat Nov 4 05:11:17 2023 -0400 runtime(dist): centralize safe executable check and add vim library (https://github.com/vim/vim/issues/13413) Follow up to 816fbcc26 (patch 9.0.1833: [security] runtime file fixes, 2023-08-31) and f7ac0ef50 (runtime: don't execute external commands when loading ftplugins, 2023-09-06). This puts the logic for safe executable checks in a single place, by introducing a central vim library, so all filetypes benefit from consistency. Notable changes: - dist#vim because the (autoload) namespace for a new runtime support library. Supporting functions should get documentation. It might make life easier for NeoVim devs to make the documentation a new file rather than cram it into existing files, though we may want cross-references to it somewhere? - The gzip and zip plugins need to be opted into by enabling execution of those programs (or the global plugin_exec). This needs documentation or discussion. - This fixes a bug in the zig plugin: code setting s:tmp_cwd was removed in f7ac0ef50 (runtime: don't execute external commands when loading ftplugins, 2023-09-06), but the variable was still referenced. Since the new function takes care of that automatically, the variable is no longer needed. Signed-off-by: D.
