In normal - * situation, its parent node would be already deflated, so it just - * needs to apply delta. + * Ensure that this node has been reconstructed and return its contents. * - * In the worst case scenario, parent node is no longer deflated because - * we're running out of delta_base_cache_limit; we need to re-deflate - * parents, possibly up to the top base. - * - * All deflated objects here are subject to be freed if we exceed - * delta_base_cache_limit, just like in find_unresolved_deltas(), we - * just need to make sure the last node is not freed. + * In the typical and best case, this node would already be reconstructed + * (through the invocation to resolve_delta() in threaded_second_pass()) and it + * would not be pruned. However, if pruning of this node was necessary due to + * reaching delta_base_cache_limit, this function will find the closest + * ancestor with reconstructed data that has not been pruned (or if there is + * none, the ultimate base object), and reconstruct each node in the delta + * chain in order to generate the reconstructed data for this node. */ static void *get_base_data(struct base_data *c) { @@ -902,7 +920,7 @@ static void *get_base_data(struct base_data *c) if (!delta_nr) { c->data = get_data_from_pack(obj); c->size = obj->size; - get_thread_data()->base_cache_used += c->size; + base_cache_used += c->size; prune_base_data(c); } for (; delta_nr > 0; delta_nr--) { @@ -918,7 +936,7 @@ static void *get_base_data(struct base_data *c) free(raw); if (!c->data) bad_object(obj->idx.offset, _("failed to apply delta")); - get_thread_data()->base_cache_used += c->size; + base_cache_used += c->size; prune_base_data(c); } free(delta); @@ -926,10 +944,27 @@ static void *get_base_data(struct base_data *c) return c->data; } -static void resolve_delta(struct object_entry *delta_obj, - struct base_data *base, struct base_data *result) +static struct base_data *make_base(struct object_entry *obj, + struct base_data *parent) +{ + struct base_data *base = xcalloc(1, sizeof(struct base_data)); + base->base = parent; + base->obj = obj; + find_ref_delta_children(&obj->idx.oid, + &base->ref_first, &base->ref_last); + find_ofs_delta_children(obj->idx.offset, + &base->ofs_first, &base->ofs_last); + base->children_remaining = base->ref_last - base->ref_first + + base->ofs_last - base->ofs_first + 2; + return base; +} + +static struct base_data *resolve_delta(struct object_entry *delta_obj, + struct base_data *base) { - void *base_data, *delta_data; + void *delta_data, *result_data; + struct base_data *result; + unsigned long result_size; if (show_stat) { int i = delta_obj - objects; @@ -942,115 +977,26 @@ static void resolve_delta(struct object_entry *delta_obj, obj_stat[i].base_object_no = j; } delta_data = get_data_from_pack(delta_obj); - base_data = get_base_data(base); - result->obj = delta_obj; - result->data = patch_delta(base_data, base->size, - delta_data, delta_obj->size, &result->size); + assert(base->data); + result_data = patch_delta(base->data, base->size, + delta_data, delta_obj->size, &result_size); free(delta_data); - if (!result->data) + if (!result_data) bad_object(delta_obj->idx.offset, _("failed to apply delta")); - hash_object_file(the_hash_algo, result->data, result->size, - type_name(delta_obj->real_type), &delta_obj->idx.oid); - sha1_object(result->data, NULL, result->size, delta_obj->real_type, + hash_object_file(the_hash_algo, result_data, result_size, + delta_obj->real_type, &delta_obj->idx.oid); + sha1_object(result_data, NULL, result_size, delta_obj->real_type, &delta_obj->idx.oid); + + result = make_base(delta_obj, base); + result->data = result_data; + result->size = result_size; + counter_lock(); nr_resolved_deltas++; counter_unlock(); -} - -/* - * Standard boolean compare-and-swap: atomically check whether "*type" is - * "want"; if so, swap in "set" and return true.
