From 86f951570839e241cfa8effbe195674193693a7f Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Nguy=E1=BB=85n=20Th=C3=A1i=20Ng=E1=BB=8Dc=20Duy?= Date: Wed, 5 Apr 2017 17:24:39 +0700 Subject: config: resolve symlinks in conditional include's patterns MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit $GIT_DIR returned by get_git_dir() is normalized, with all symlinks resolved (see setup_work_tree function). In order to match paths (or patterns) against $GIT_DIR char-by-char, they have to be normalized too. There is a note in config.txt about this, that the user need to resolve symlinks by themselves if needed. The problem is, we allow certain path expansion, '~/' and './', for convenience and can't ask the user to resolve symlinks in these expansions. Make sure the expanded paths have all symlinks resolved. PS. The strbuf_realpath(&text, get_git_dir(), 1) is still needed because get_git_dir() may return relative path.
