From ed4efab1b17e883b761b4482c40c04a4529be8f9 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Nguy=E1=BB=85n=20Th=C3=A1i=20Ng=E1=BB=8Dc=20Duy?= Date: Sun, 8 Mar 2015 17:12:37 +0700 Subject: untracked cache: avoid racy timestamps MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When a directory is updated within the same second that its timestamp is last saved, we cannot realize the directory has been updated by checking timestamps. Assume the worst (something is update). See 29e4d36 (Racy GIT - 2005-12-20) for more information.
