From 6966073102170171da4c25a4038bbd143fa6a75b Mon Sep 17 00:00:00 2001 From: Jeff King Date: Tue, 21 Aug 2012 02:26:07 -0400 Subject: [PATCH] gitignore: report access errors of exclude files When we try to access gitignore files, we check for their existence with a call to "access". We silently ignore missing files. However, if a file is not readable, this may be a configuration error; let's warn the user. For $GIT_DIR/info/excludes or core.excludesfile, we can just use access_or_warn. However, for per-directory files we actually try to open them, so we must add a custom warning.
