As discussed in a preceding commit this allows for using OPT_SUBCOMMAND() with custom function signatures. It would be nice to also convert all of the callbacks to use parse_options(), [1] does. But due to using the new OPT_SUBCOMMAND_CB() here we can punt on that for now. Note that we're intentionally leaving the errors which mention "--bisect-terms", as opposed to "terms". We've been showing that bad usage information to users for a while now, and don't need to further enlarge this change now by changing all of "--bisect-" to "" (which also occurs outside of this context). This finally fixes the last obscure regression in "git bisect run" in v2.30.0. We'd previously addressed it eating the "--log" and "--no-log" options, but d1bbbe45df8 (bisect--helper: reimplement `bisect_run` shell function in C, 2021-09-13) also had us conflate the internal-only "--bisect-*" options with user arguments. 1. https://lore.kernel.org/git/e97e187bbec93b47f35e3dd42b4831f1c1d8658d.1661885419.git.gitgitgadget@gmail.com/ Signed-off-by: Ævar Arnfjörð Bjarmason --- builtin/bisect--helper.c | 110 ++++++++++++++---------------------- git-bisect.sh | 20 +++---- parse-options.h | 8 ++- t/t6030-bisect-porcelain.sh | 2 +- 4 files changed, 59 insertions(+), 81 deletions(-) diff --git a/builtin/bisect--helper.c b/builtin/bisect--helper.c index e13c60d54b2..b62d3f4d418 100644 --- a/builtin/bisect--helper.c +++ b/builtin/bisect--helper.c @@ -1314,107 +1314,79 @@ static int bisect_run(struct bisect_terms *terms, int argc, return res;
