Hi, I was able to narrow down the problem and I do have an idea for a fix.
diff --git a/builtin/backfill.c b/builtin/backfill.c index 33e1ea2f84..18f9701487 100644 --- a/builtin/backfill.c +++ b/builtin/backfill.c @@ -123,7 +123,7 @@ int cmd_backfill(int argc, const char **argv, const char *prefix, struct reposit .sparse = 0, }; struct option options[] = { - OPT_INTEGER(0, "min-batch-size", &ctx.min_batch_size, + OPT_MAGNITUDE(0, "min-batch-size", &ctx.min_batch_size, N_("Minimum number of objects to request at a time")), OPT_BOOL(0, "sparse", &ctx.sparse, N_("Restrict the missing objects to the current sparse-checkout")), This is passing all of the test cases. But with this change a size_t pointer is being cast to an unsigned long pointer. This could potentially lead to some issue in some architecture. If I can verify that the min_batch_size variable (which is a size_t var) is not taking a value larger than an int could store, then we can change its data type from size_t to int. So, I was checking if there is any evidence that indicates a potential range for min_batch_size. I was also planning to ping with the upstream community for clarification.
