From 721ac4edde75723ef8dbbb68989bda89fbf6fc66 Mon Sep 17 00:00:00 2001 From: Antoine Pelisse Date: Sun, 30 Dec 2012 15:39:00 +0100 Subject: [PATCH 1/3] dir.c: Make git-status --ignored more consistent The current behavior of git-status is inconsistent and misleading. Especially when used with --untracked-files=all option: - files ignored in untracked directories will be missing from status output. - untracked files in committed yet ignored directories are also missing. - with --untracked-files=normal, untracked directories that contains only ignored files are dropped too. Make the behavior more consistent across all possible use cases: - "--ignored --untracked-files=normal" doesn't show each specific files but top directory. It instead shows untracked directories that only contains ignored files, and ignored tracked directories with untracked files. - "--ignored --untracked-files=all" shows all ignored files, either because it's in an ignored directory (tracked or untracked), or because the file is explicitly ignored.

The "index knows about" check is done by consulting the name hash, not the actual contents of the index: - When core.ignorecase is false, directory names are not in the name hash, and ignored ones are shown as ignored (directories can never be tracked anyway). - When core.ignorecase is true, however, the name hash keeps track of the names of directories, in order to detect additions of the paths under different cases. This causes ignored directories to be mistakenly excluded when enumerating ignored paths. Stop excluding directories that are in the name hash when looking for ignored files in dir_add_name(); the names that are actually in the index are excluded much earlier in the callchain in treat_file(), so this fix will not make them mistakenly identified as ignored.
