Subject: [PATCH 1/7] t1300: test "set all" mode with value_regex
Date: Thu, 19 Nov 2020 15:52:17 +0000
Message-ID: <2da2131114eb47e70ccaf8fb9c51bf7fb5b173b0.1605801143.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.796.git.1605801143.gitgitgadget@gmail.com>

From: Derrick Stolee <dstolee@microsoft.com>

Without additional modifiers, 'git config' attempts to set a single
value in the .git/config file. When the value_regex parameter is
supplied, this command behaves in a non-trivial manner.

Consider 'git config key value value_regex'. The expected behavior
is as follows:

1. If there are multiple existing values that match 'value_regex',
   then the command fails. Users should use --replace-all instead.

2. If there is one existing value that matches 'value_regex', then
   the new config has one entry where 'key=value'.

3. If there is no existing values match 'value_regex', then the
   'key=value' pair is appended, making this 'key' a multi-valued
   config setting.

Add a test that demonstrates these options.
