Since you are not sending '--no-sparse' when the variable 'sparse' is zero, the config setting will automatically be picked up by the pack-objects builtin. Now, a question of whether you _should_ allow the '--no-sparse' option in the 'repack' command, and send it along to the inner command (when it is present) is another question. > @@ -366,6 +374,8 @@ int cmd_repack(int argc, const char **argv, const char *prefix) > argv_array_push(&cmd.args, "--all"); > argv_array_push(&cmd.args, "--reflog"); > argv_array_push(&cmd.args, "--indexed-objects"); > + if (sparse) > + argv_array_push(&cmd.args, "--sparse"); > if (repository_format_partial_clone) > argv_array_push(&cmd.args, "--exclude-promisor-objects"); > if (write_bitmaps) > How about a test with this new option? You can probably just add to t5322-pack-objects-sparse.sh. Thanks, -Stolee
