Subject: [PATCH v5 2/3] reftable/stack: add env to disable autocompaction
Date: Thu, 04 Apr 2024 18:29:28 +0000 [thread overview]
Message-ID: <7c4fe0e9ec597203ee37d2c2503be319e87ff5ee.1712255369.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1683.v5.git.1712255369.gitgitgadget@gmail.com>
From: Justin Tobler <jltobler@gmail.com>
In future tests it will be neccesary to create repositories with a set
number of tables. To make this easier, introduce the
`GIT_TEST_REFTABLE_AUTOCOMPACTION` environment variable that, when set
to false, disables autocompaction of reftables.
