Subject: [PATCH v2 0/2] Date test code clean-up
Date: Wed, 11 Sep 2019 21:11:00 -0700	[thread overview]
Message-ID: <20190912041102.16266-1-ischis2@cox.net> (raw)
In-Reply-To: <20190909014711.3894-1-ischis2@cox.net>

As part of a previous patch submission[1], a cleanup patch was
suggested to remove a now unnecessary passing of a date environment
variable to the production code.

While the two patches in the set could easily be submitted as a single
patch, I split the removal of the getenv() call into a second
patch. I did that to make the comment about the initialization of `x`
more localized to the change.

         Quit passing 'now' to date code
     
    -    As part of a previous patch set, the get_time() function was added to
    -    date.c eliminating the need to pass a `now` parameter from the test
    -    code.
    +    Commit b841d4ff43 (Add `human` format to test-tool, 2019-01-28) added
    +    a get_time() function which allows $GIT_TEST_DATE_NOW in the
    +    environment to override the current time. So we no longer need to
    +    interpret that variable in cmd__date().
     
    -    This patch removes the unneeded `now` parameter.
    +    Therefore, we can stop passing the "now" parameter down through the
    +    date functions, since nobody uses them. Note that we do need to make
    +    sure all of the previous callers that took a "now" parameter are
    +    correctly using get_time().

         Remove the reference to the GIT_TEST_DATE_NOW which is done in date.c.
    -    The intialization of variable x with the value from GIT_TEST_DATE_NOW
    -    is unneeded since x is initalized by skip_prefix().
    +    We can't get rid of the "x" variable, since it serves as a generic
    +    scratch variable for parsing later in the function.
