From c937d70bfb7661d5122e08758ae0531073a719ed Mon Sep 17 00:00:00 2001 From: Matheus Tavares Date: Mon, 22 Feb 2021 22:10:33 -0300 Subject: [PATCH 1/3] add --chmod: don't update index when --dry-run is used `git add --chmod` applies the mode changes even when `--dry-run` is used. Fix that and add some tests for this option combination.

Also use error() instead of fprintf(stderr, ...), to make the corresponding line a bit cleaner, and to display the "error:" prefix, which helps classifying the nature/severity of the message.

This might have been an oversight, as the command does exit with a non-zero code in other situations where it cannot (or refuses to) update all of the requested paths (e.g. when some of the given paths are ignored). So make the exit behavior more consistent by also propagating --chmod errors to the exit status. Note: the test "all statuses changed in folder if . is given" uses paths added by previous test cases, some of which might be symbolic links. Because `git add --chmod` will now fail with such paths, this test would depend on whether all the previous tests were executed, or only some of them. Avoid that by running the test on a fresh repo with only regular files.
