From 441a327051f5357175029709030a0ee51131379d Mon Sep 17 00:00:00 2001 From: =?utf8?q?=C4=90o=C3=A0n=20Tr=E1=BA=A7n=20C=C3=B4ng=20Danh?= Date: Sat, 24 Apr 2021 08:05:37 +0700 Subject: [PATCH] compat: rename {,notmuch_}canonicalize_file_name MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit When compat canonicalize_file_name was introduced, it was limited to C code only because it was used by C code only during that time. >From 5ec6fd4d, (lib/open: check for split configuration when creating database., 2021-02-16), lib/open.cc, which is C++, relies on the existent of canonicalize_file_name. However, we can't blindly enable canonicalize_file_name for C++ code, because different implementation has different additional signature for C++ and users can arbitrarily add -DHAVE_CANONICALIZE_FILE_NAME=0 to {C,CXX}FLAGS. Let's move our implementation into a util library.
