I would avoid making such changes if I were doing this patch. The _real_ change in the above hunk is that a new struct instance "opts" is defined, with its .flags member initialized based on what fetch_pack_fsck_object() says. That helper function requires us to be in a repository, but because you must have a repository to unbundle into, that call is safe. > @@ -379,8 +383,7 @@ static int unbundle_from_file(struct repository *r, const char *file) > * a reachable ref pointing to the new tips, which will reach > * the prerequisite commits. > */ > - result = unbundle(r, &header, bundle_fd, NULL, > - VERIFY_BUNDLE_QUIET | (fetch_pack_fsck_objects() ?

It looked as if the patch is adding an extra parameter, until I read it again. The real change here is that the enum is replaced with a struct that has the same enum as one of its members, which is good. Name the external-facing one (like this new parameter) _without_ funnies, and call it straight "opts". The internal stand-in object you create below can use funny convention but using "_" as prefix is usually for system stuff (and the language standard forbids it, even though people often do so in practice, from programs). > { > struct child_process ip = CHILD_PROCESS_INIT; > + struct verify_bundle_opts opts = { 0 }; > > - if (verify_bundle(r, header, flags)) > + if (_opts) > + opts = *_opts; > + > + if (verify_bundle(r, header, opts.flags)) > return -1; This is an arrangement that looks strange, especially at this stage of the series without reading the rest. If verify_bundle() takes the enum and not &opts, there is no need for stand-in opts struct. You can have a local enum "flags" that is initialized to 0 and only when parameter "opts" is not NULL, assign opts->flags to it and use it throughout the rest of the function. Reviewers will be left confused wondering why the patch does this in an unnecessarily more complex way by using an extra structure instance. Until you start needing other fields of opts in the function, perhaps in a later step, that is. > @@ -641,7 +645,7 @@ int unbundle(struct repository *r, struct bundle_header *header, > if (header->filter.choice) > strvec_push(&ip.args, "--promisor=from-bundle"); > > - if (flags & VERIFY_BUNDLE_FSCK) > + if (opts.flags & VERIFY_BUNDLE_FSCK) > strvec_push(&ip.args, "--fsck-objects"); And this is a fallout of the above "strange" arrangement. > { > + struct verify_bundle_opts opts = { .flags = fetch_pack_fsck_objects() ? > + VERIFY_BUNDLE_FSCK : 0 }; struct verify_bundle_opts opts = { .flags = fetch_pack_fsck_objects() ?

Bundle verification performed as part of `unbundle()` is configurable via providing `verify_bundle_flags`. This is done by invoking `verify_bundle()` and propagating the set flags. If the `VERIFY_BUNDLE_FSCK` flag is provided, the `fsck-objects` flag is specified when invoking git-index-pack(1) to perform fsck checks on the objects in the bundle. Introduce a new type, `verify_bundle_opts`, and update `unbundle()` to accept this instead of `verify_bundle_flags` to perform the same verification configuration. In a subsequent commit, `verify_bundle_opts` will be extended to support configuration of fsck message severity.
