Re: Trying to add more tests to gistbuild.c

Hi Matheus,

Many thanks for hacking on increasing the code coverage! I noticed
that this patch was stuck in "Needs Review" state for some time and
decided to take a look.

I can confirm that the coverage improved as stated.

Personally I believe this change makes perfect sense. Although this is
arguably not an ideal test for gistInitBuffering(), writing proper
tests for `static` procedures is generally not an easy task. Executing
the code at least once in order to make sure that it doesn't crash,
doesn't throw errors and doesn't violate any Asserts() is better than
doing nothing.

Here is a slightly modified patch with added commit message. Please
note that patches created with `git format-patch` are generally
preferable than patches created with `git diff`.

I'm going to change the status of this patch to "Ready for Committer"
in a short time unless anyone has a second opinion.
