Subject: [PATCH v3 08/11] builtin/diagnose.c: add '--mode' option
Date: Wed, 10 Aug 2022 23:34:30 +0000 [thread overview]
Message-ID: <3da0cb725c927d08dd9486286e06bdb76896f5b7.1660174473.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1310.v3.git.1660174473.gitgitgadget@gmail.com>
From: Victoria Dye <vdye@github.com>
Create '--mode=<mode>' option in 'git diagnose' to allow users to optionally
select non-default diagnostic information to include in the output archive.
Additionally, document the currently-available modes, emphasizing the
importance of not sharing a '--mode=all' archive publicly due to the
presence of sensitive information.
Note that the option parsing callback - 'option_parse_diagnose()' - is added
to 'diagnose.c' rather than 'builtin/diagnose.c' so that it may be reused in
future callers configuring a diagnostics archive.
