eos原始账户创建流程02

本图主要内容：创建账号这个“action”的“行为”

authorization_manger.cppget_permission(declared_auth).satisfies( min_permission...验证最小权限

dispatch分发

require_authorization(create.creator)传入user

vlaue_type 为 account_objecttype_id为枚举值account_object_type

apply_context::exec_one

_index_map[index_type::value_type::type_id]-get()

app().get_method().register

db之创建原始账号

elliptic.hpp:signature_shim::recover

eosio_contract.cpp:apply_eosio_newaccount(apply_context& context)

secp256k1_ecdsa_recover_compact

new_account = db.create

运行合约：controllor.cpp:trx_context.exec();

main.cpp:fc::variant push_transaction

cleos

签名signature数据结构里面有个存放签名的地方，storage_type _storage;它是static_variant类型的。templateclass static_variant{ alignas(Types...) char storage[impl::type_info::size]; .......}这个数组用来存放Types中某一类型的数据。就是把这个对象按字节全部存放在storage中。

nodeos

const auto& new_account = db.create([&](auto& a) { a.name = create.name; a.creation_date = context.control.pending_block_time(); });

chain_plugin.cpp:read_write::push_transaction

produce_plugin.cpp:on_incoming_transaction_async

controller.cpp:push_transaction

produce_plugin.cpp:chain.push_transaction

app().get_method()....

从签名中提取公钥，然后checker验证签名
