Subject: [PATCH v6 18/19] sparse-checkout: update working directory in-process for 'init'
Date: Thu, 21 Nov 2019 22:04:50 +0000 [thread overview]
Message-ID: <c62d9750efe992f13cb2fa8c71120ffa0f850ae3.1574373892.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.316.v6.git.1574373891.gitgitgadget@gmail.com>
From: Derrick Stolee <dstolee@microsoft.com>
The 'git sparse-checkout init' subcommand previously wrote directly
to the sparse-checkout file and then updated the working directory.
This may fail if there are modified files not included in the initial
pattern set. However, that left a populated sparse-checkout file.
Use the in-process working directory update to guarantee that the
init subcommand only changes the sparse-checkout file if the working
directory update succeeds.
