Subject: [PATCH v3 3/5] repo-settings: parse core.untrackedCache
Date: Tue, 30 Jul 2019 12:35:28 -0700 (PDT)	[thread overview]
Message-ID: <b0a2d0e18800da01ab1b17faca34eb011fb36128.1564515324.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.292.v3.git.gitgitgadget@gmail.com>

From: Derrick Stolee <dstolee@microsoft.com>

The core.untrackedCache config setting is slightly complicated,
so clarify its use and centralize its parsing into the repo
settings.

The default value is "keep" (returned as -1), which persists the
untracked cache if it exists.

If the value is set as "false" (returned as 0), then remove the
untracked cache if it exists.

If the value is set as "true" (returned as 1), then write the
untracked cache and persist it.

Instead of relying on magic values of -1, 0, and 1, split these
options into an enum. This allows the use of "-1" as a
default value. After parsing the config options, if the value is
unset we can initialize it to UNTRACKED_CACHE_KEEP.
