From: Johannes Schindelin Date: Wed, 30 Oct 2019 10:49:37 +0000 (+0000) Subject: update-index: optionally leave skip-worktree entries alone X-Git-Tag: v2.25.0-rc0~136^2~1 X-Git-Url: http://git.ipfire.org/?p=thirdparty%2Fgit.git;a=commitdiff_plain;h=8dfb04ae964868dda758997e5e7da29edff6164b update-index: optionally leave skip-worktree entries alone While `git update-index` mostly ignores paths referring to index entries whose skip-worktree bit is set, in b4d1690df11 (Teach Git to respect skip-worktree bit (reading part), 2009-08-20), for reasons that are not entirely obvious, the `--remove` option was made special: it _does_ remove index entries even if their skip-worktree bit is set. Seeing as this behavior has been in place for a decade now, it does not make sense to change it. However, in preparation for fixing a bug in `git stash` where it pretends that skip-worktree entries have actually been removed, we need a mode where `git update-index` leaves all skip-worktree entries alone, even if the `--remove` option was passed.
