From 059fda190215d18e7aa23f825cd607b16a016b65 Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Tue, 8 Feb 2022 11:21:53 +0000 Subject: checkout/fetch/pull/pack-objects: allow `-h` outside a repository 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`.
