From 11dc1fcb3fa53f5a46486daa7cb38ed387153f2e 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, 3 May 2017 17:16:49 +0700 Subject: wrapper.c: add and use warn_on_fopen_errors() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In many places, Git warns about an inaccessible file after a fopen() failed. To discern these cases from other cases where we want to warn about inaccessible files, introduce a new helper specifically to test whether fopen() failed because the current user lacks the permission to open file in question.
