Subject: [PATCH v3 11/22] perf: add performance test for pickaxe
Date: Mon, 12 Apr 2021 19:15:18 +0200	[thread overview]
Message-ID: <patch-11.22-97616d741c7-20210412T170457Z-avarab@gmail.com> (raw)
In-Reply-To: <cover-00.22-00000000000-20210412T170457Z-avarab@gmail.com>

Add a test for the -G and -S pickaxe options and related options.

This test supports being run with GIT_TEST_LONG=1 to adjust the limit
on the number of commits from 1k to 10k. The 1k limit seems to hit a
good spot on git.git
