From bacae540479e7dc84bfbd059a20afa2ef00e8cdb Mon Sep 17 00:00:00 2001
From: mrossetti <mrossetti@chromium.org>
Date: Tue, 31 May 2011 23:12:11 +0000
Subject: [PATCH 03/10] Exclude journal file from Time Machine if database is
excluded.
BUG=74053
Original review URL: http://codereview.chromium.org/6990066
TODO(shess): The fts3_porter.c change is due to a conflict with an included
Apple library. Perhaps move the operative code to a .c file, and firewall
SQLite from that include.
TODO(shess): Revisit this for -wal mode. http://crbug.com/78507
