+[MySQL](https://www.mysql.com/)是著名的开源的关系型数据库，为了使用户更快捷地访问mysql并充分利用bthread的并发能力，brpc直接支持mysql协议。示例程序：[example/mysql_c++](https://github.com/brpc/brpc/tree/master/example/mysql_c++/) + +**注意**：只支持MySQL 4.1 及之后的版本的文本协议，支持事务，支持Prepared statement。目前支持的鉴权方式为mysql_native_password，使用事务的时候不支持single模式。 + +相比使用[libmysqlclient](https://dev.mysql.com/downloads/connector/c/)(官方client)的优势有： + +- 线程安全。用户不需要为每个线程建立独立的client。 +- 支持同步、异步、半同步等访问方式，能使用[ParallelChannel等](combo_channel.md)组合访问方式。 +- 支持多种[连接方式](client.md#连接方式)。支持超时、backup request、取消、tracing、内置服务等一系列brpc提供的福利。 +- 明确的返回类型校验，如果使用了不正确的变量接受mysql的数据类型，将抛出异常。 +- 调用mysql标准库会阻塞框架的并发能力，使用本实现将能充分利用brpc框架的并发能力。 +- 使用brpc实现的mysql不会造成pthread的阻塞，使用libmysqlclient会阻塞pthread [线程相关](bthread.md)，使用mysql的异步api会使编程变得很复杂。 +#

+这个结果就和brpc框架启动100个bthread访问mysql的效果类似了。 + + + +以上为我的一些简单测试，以及一些简单的分析，在低并发的情况下同步IO的效率高于异步IO，可以阅读[IO相关的内容](io.md)有更多解释，后续还将继续分析性能问题，优化协议，给出更多测试。 \ No newline at end of file diff --git

the **second** login must reuse the cache (fast-auth), never `0x04` | + +## Mode 1 — self-spawned server (default; CI) + +When `-mysql_use_running_server` is **not** set, the fixture brings up its +own throwaway `mysqld` (the `which`-then-spawn pattern from +`brpc_redis_unittest.cpp`) with an empty-password root, and tears it down +on exit. `caching_sha2_password` then completes via its empty-password +fast path. `PerformsFullAuthentication` skips here (an empty password +never triggers full auth); the other three run. Tests self-skip entirely +when `mysqld` is absent. + +```sh +cd test && ./brpc_mysql_auth_handshake_unittest +``` + +## Mode 2 — already-running server (recommended for development & future CLs) + +You start a `mysqld` yourself, with verbose logging so you can watch the +handshake, and point the tests at it with flags. The test neither starts +nor stops it. Reuse this workflow as more of the MySQL protocol lands +(text protocol, prepared statements, transactions). + +### 1. Initialize a data directory (one time per fresh instance) + +```sh +export MYSQL_DATA=/tmp/brpc_mysql_e2e +export MYSQL_PORT=13306 +rm -rf "$MYSQL_DATA" && mkdir -p "$MYSQL_DATA" +mysqld --initialize-insecure --datadir="$MYSQL_DATA" --log-error="$MYSQL_DATA/init.err" +``` + +### 2.

It is +the first authenticating test, so against a **freshly started** server it +sees the full-auth path.

It asserts +// a brpc-ARCHITECTURE boundary: how a MySQL prepared statement (whose +// server-side handle is connection-scoped) interacts with brpc's +// CONNECTION_TYPE_SHORT (a fresh TCP connection per request). The data values +// are this file's own; no upstream test code or structure was copied. +// +// THE BOUNDARY (spec fact, asserted -- not derived from our impl) +// -------------------------------------------------------------- +// A MySQL prepared statement is created with COM_STMT_PREPARE on ONE TCP +// connection; the server returns a `stmt_id` that is valid ONLY on that exact +// connection. COM_STMT_EXECUTE must therefore run on the SAME connection. +// +// CONNECTION_TYPE_SHORT opens a brand-new TCP connection for every request and +// closes it afterwards, so there is no connection affinity across requests. +// To keep prepared statements usable under SHORT, the brpc MySQL client keys +// each cached stmt_id by (SocketId, fd_version) and, when it finds no valid +// handle for the fresh connection, transparently RE-PREPARES the statement on +// that connection before executing. So execute under SHORT SUCCEEDS -- at the +// cost of an extra prepare round-trip per request. +// +// * PreparedStatementUnderShortRePreparesAndSucceeds (PRIMARY): +// build a SHORT channel, prepare "SELECT ? AS v", bind one INT param, +// CallMethod. Must SUCCEED (NOT cntl.Failed(), NOT reply(0).is_error()) +// and return the bound value as a 1-row result set; must NOT crash. +// Looped a few times so each iteration exercises a fresh connection. +// +// * PlainQueryUnderShortMustSucceed (POSITIVE CONTROL): +// same SHORT channel; a stateless COM_QUERY "SELECT 7 AS v" must SUCCEED +// and return 7. Proves SHORT is fine for stateless queries; only the +// connection-scoped prepared-statement handle breaks under SHORT. +// +// HARNESS +// ------- +// Reuses the gflag-driven, self-spawning-mysqld harness from the sibling +// integration files (flags -mysql_use_running_server / -mysql_host / -port / +// -user / -password; MysqlAuthenticator-based channel).

It RE-RUNS, concurrently, the SAME self-checking work units that +// the two sibling integration files already cover serially: +// +// * brpc_mysql_txn_integration_unittest.cpp (transaction scenarios) +// * brpc_mysql_prepared_integration_unittest.cpp (prepared-statement +// scenarios) +// +// The work-unit bodies (SQL shape + the self-check) mirror those siblings; +// only the literal DATA VALUES are changed (different ids/strings/numbers) so +// this file does not duplicate any other file's data and so that cross-talk +// between concurrent workers is detectable by value. +// +// The CONCURRENCY HARNESS itself -- many bthreads hammering ONE pooled Channel, +// asserting connection affinity / isolation -- exercises brpc's own +// connection-affinity model (a brpc POOLED Channel must check out / return +// pooled sockets without races, must PIN one socket per MysqlTransaction, and +// must keep concurrent transactions / prepared statements isolated). It is +// modeled on how brpc's other pooled/parallel-bthread unittests drive a pooled +// Channel from several bthreads at once. +// +// WHAT IT CHECKS +// -------------- +// ConnectionType = POOLED, pool capped at FIVE connections via the gflag +// `max_connection_pool_size` (DEFINE_int32 max_connection_pool_size in +// src/brpc/socket.cpp:99). FIVE (not 2) is deliberate: with more workers than +// pooled sockets we exercise BOTH pooled-socket reuse AND the create-a-NEW- +// connection-under-load path concurrently, surfacing checkout/return races, +// transaction connection-affinity/pinning under contention, and fd_version ABA. +// +// * ManyWorkersMixedScenarios: +// 16-32 bthreads, each looping ~50x, each iteration picks ONE of five +// representative self-checking work units (3 txn + 2 prepared) and +// asserts its OWN correct, independent result. Per-worker scratch tables +// / per-iteration ids keep row-count assertions exact under concurrency. +// +// * TwoTransactionsHoldDifferentPinnedSockets (focused check a): +// two transactions in parallel must hold DIFFERENT pinned SocketIds +// (GetSocketId()) and must not see each other's rows. +// +// * TransactionPlusPreparedInParallel (focused check b): +// one transaction + one prepared statement in parallel, each returns its +// own correct independent result; the prepared path must not disturb the +// transaction's pinned connection. +// +// The bar: NO concurrency bug across all iterations -- no shared-socket +// corruption, no interleaved/wrong replies, no crash. +// +// HARNESS +// ------- +// Reuses the gflag-driven, self-spawning-mysqld harness from the two sibling +// integration files (flags -mysql_use_running_server / -mysql_host / -port / +// -user / -password / -schema; MysqlAuthenticator-based pooled Channel).
