From: Justin Tobler via GitGitGadget Date: Thu, 04 Apr 2024 18:29:28 GMT Subject: [PATCH v5 2/3] reftable/stack: add env to disable autocompaction Message-ID: <7c4fe0e9ec597203ee37d2c2503be319e87ff5ee.1712255369.git.gitgitgadget@gmail.com> In-Reply-To: From: Justin Tobler 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.
