From 5698454ea052369dc98d38b45c21307b07a6c4a3 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sat, 14 Apr 2007 16:22:08 -0700 Subject: [PATCH] Fix some "git ls-files -o" fallout from gitlinks Since "git ls-files" doesn't really pass down any details on what it really wants done to the directory walking code, the directory walking code doesn't really know whether the caller wants to know about gitlink directories, or whether it wants to just know about ignored files. So the directory walking code will return those gitlink directories unless the caller has explicitly told it not to ("dir->show_other_directories" tells the directory walker to only show "other" directories). This kind of confuses "git ls-files -o", because - it didn't really expect to see entries listed that were already in the index, unless they were unmerged, and would die on that unexpected setup, rather than just "continue". - it didn't know how to match directory entries with the final "/" This trivial change updates the "show_other_files()" function to handle both of these issues gracefully. There really was no reason to die, when the obviously correct thing for the function was to just ignore files it already knew about (that's what "other" means here!).
