Subject: [PATCH 2/5] t1400: set core.logAllRefUpdates in "logged by touch" tests

From: Kyle Meyer <[email-masked]>
Date: Mon, 20 Mar 2017 20:56:13 -0400

A group of update-ref tests verifies that logs are created when either
the log file for the ref already exists or core.logAllRefUpdates is
"true".  However, when the default for core.logAllRefUpdates was
changed in 0bee59186 (Enable reflogs by default in any repository with
a working directory., 2006-12-14), the setup for the tests was not
updated.  As a result, the "logged by touch" tests would pass even if
the log file did not exist (i.e., if "--create-reflog" was removed
from the first "git update-ref" call).

Update the "logged by touch" tests to disable core.logAllRefUpdates
explicitly so that the behavior does not depend on the default value.
While we're here, update the "logged by config" tests to use
test_config() rather than setting core.logAllRefUpdates to "true"
outside of the tests.

I'm confused about the setup for the "logged by touch" tests.
d0ab05849 (tests: remove some direct access to .git/logs, 2015-07-27)
changed the setup to delete the log file itself rather than its
contents.  The reflog was then recreated by using "--create-reflog" in
the "create $m (logged by touch)" test.  What I don't understand is
how this change fits with d0ab05849, which seems to be concerned with
loosening the assumption that the logs are stored in .git/logs.  For
these particular tests, we are still removing
.git/logs/refs/heads/master explictly, so why not leave the empty file
around so that the "create $m (logged by touch)" actually tests that
update-ref call is logged by the existence of the log rather than
using "--create-reflog", which overrides this?
