Subject: [PATCH v2 1/2] checkout/fetch/pull/pack-objects: allow `-h` outside a repository
Date: Tue, 08 Feb 2022 11:21:53 +0000 [thread overview]
Message-ID: <6e9cdd10a70801da5124db1f55770d05c002671d.1644319314.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1139.v2.git.1644319314.gitgitgadget@gmail.com>
From: Johannes Schindelin <johannes.schindelin@gmx.de>
When we taught these commands about the sparse index, we did not account
for the fact that the `cmd_*()` functions _can_ be called without a
gitdir, namely when `-h` is passed to show the usage.
A plausible approach to address this is to move the
`prepare_repo_settings()` calls right after the `parse_options()` calls:
The latter will never return when it handles `-h`, and therefore it is
safe to assume that we have a `gitdir` at that point, as long as the
built-in is marked with the `RUN_SETUP` flag.
However, it is unfortunately not that simple. In `cmd_pack_objects()`,
for example, the repo settings need to be fully populated so that the
command-line options `--sparse`/`--no-sparse` can override them, not the
other way round.
Therefore, we choose to imitate the strategy taken in `cmd_diff()`,
where we simply do not bother to prepare and initialize the repo
settings unless we have a `gitdir`.
This fixes https://github.com/git-for-windows/git/issues/3688
