Subject: [GSoC][PATCH] test: avoid pipes in git related commands for test suite
Date: Mon, 19 Mar 2018 23:17:04 +0545
Message-ID: <20180319173204.31952-1-predatoramigo@gmail.com> (raw)
In-Reply-To: <xmqqsh915kzi.fsf@gitster-ct.c.googlers.com>

Thank you Eric Sunshine,

I have done as you had instructed me. I look forward to more
understanding of the codebase and would love to fix
"git rev-parse" problems in my follow-on patches.
Thank you for the professional review comment.

Sorry for late follow-on patch, I got tied up with my university stuffs.

Please do review this patch as before. I will correct it if needed.

Cheers,
Pratik Karki

Avoid using pipes downstream of Git commands since the exit codes
of commands upstream of pipes get swallowed, thus potentially
hiding failure of those commands. Instead, capture Git command
output to a file apply the downstream command(s) to that file.
