From 529d21f28e65e537fde2094c9fa3f56a72024bc2 Mon Sep 17 00:00:00 2001 From: Jacob Quinn Date: Sat, 22 Aug 2026 07:51:15 -0600 Subject: [PATCH 001/162] Native wire protocol, M1: constants, bounded codecs, framing, phase machine, fake peer First milestone of the native (Connector/C-free) backend, as an isolated `MySQL.Protocol` module with no DBInterface/Tables dependency: - constants generated from the server headers (`scripts/gen_constants.jl` over my_command.h / mysql_com.h / field_types.h, SHA-256 of the inputs stamped), MariaDB extended capability bits, load-time asserts that guard the documented vendor defects (COM_SET_OPTION = 0x1B); - bounds-checked byte cursor and lenenc/fixed-int codecs; packet reader/writer with 0xFFFFFF chunking, the empty-terminator rule, sequence validation and every `Limits` check applied before a buffer grows; - the command-specific phase machine (`phases.jl`) with a transition log; the test suite asserts every transition row is exercised; - HandshakeV10 / SSLRequest / HandshakeResponse41, capability negotiation, MariaDB version normalization, phase-aware OK/EOF/ERR/LOCAL-INFILE/auth discriminators, column definitions, command/response framing, a `Session` whose transport is replaced in place at STARTTLS; - `FaultTransport` fault injection and a scripted loopback fake peer covering malformed, limit and interruption cases; vendor golden hex vectors; - Reseau TCP/TLS transports only: no `Sockets` dependency (Unix sockets and named pipes are deferred), so the protocol tests run on every CI lane without Docker. `docs/protocol-notes.md` records the sources of truth, the vendor conflicts and the clean-room rules.

Tests: OAEP round trips through a test-side decrypt for 2048/3072/4096-bit keys, nondeterminism, length boundary, malformed/EC keys, a 20k-iteration leak check; scramble verification with the server-side formulas; the policy gates and the caching_sha2 continuation state machine; full exchanges against the fake peer (fast, refused-by-default, TLS cleartext, RSA with key retrieval and local keys, auth switch, unsupported switch, MariaDB native, wrong password, sha256, cleartext gating). Test PKI under `test/protocol/certs/` (`gen.sh`).

Tests: the ssl_mode matrix against a Reseau-TLS fake peer (preferred with and without server TLS, disabled, required against a TLS-less server, verify_ca against a self-signed chain with no fallback, verify_identity with IP SAN, DNS-only certificate, ssl_server_name override, mutual TLS on TLS 1.2, 1.3 and the mixed-version path, a coalescing peer, stalls at the greeting, the TLS handshake and the auth reply under connect_timeout, init_command); the options truth table, conflict table and option files; reaper exactly-once and descriptor-count tests; and live lanes (`MYSQL_NATIVE_IMAGES`, default mysql:8.4 + mariadb:11.4) proving fast vs full vs RSA caching_sha2, the auth switch to native accounts, sha256 over TLS and RSA, access-denied errors and the utf8mb4 bootstrap against real servers. The mixed-version mutual-TLS case needs Reseau with JuliaServices/Reseau.jl#150.

Over TLS the database was silently dropped (the server read the db string as the plugin name and recovered through an auth switch). `LocalInfileRefused.filename` is a `String` (the handler contract).

Streaming cursors read into their own buffer and are invalidated (`ProtocolError`) by a foreign command, reconnect or close; buffered cursors hold one contiguous buffer plus row offsets under the per-command `max_buffered_bytes` budget (shared by every retained result of the command; exceeding it faults the session) and stay readable afterwards. `names/types/lookup` (last duplicate wins), `rows_affected` (Int64 bitcast), `length` (0 for DML results, -1 while streaming), `eltype == TextRow`, `Tables.schema`/`isrowtable` follow 1.x. - `executemultiple` yields a distinct cursor per result — DML/OK results and CALL's final OK as empty cursors with their own snapshot; advancing past an unconsumed streaming result drains it and stales its rows; a later ERR ends the iteration with `Error`. - LOCAL INFILE state table: a handler returning `nothing` always raises `LocalInfileRefused` (even when the server accepts the empty upload); a handler error before any data is re-raised after resynchronizing; a failure after data closes the connection; an unsolicited request is a `ProtocolError` and never reaches the handler. - Reconnect is narrow: only before a send, only from a session known closed or broken, never inside a transaction, bumping the generation. `transaction` holds the connection lock across the callback. - `lastrowid` is the cursor's own OK/terminator snapshot. Tests (`cursor_tests.jl`, fake peer): decoding of every mapped type, NULLs, the row-validity contract, TIME/zero-date policies, DML snapshots and the bitcast, streaming ownership/invalidation/close!, the multi-result contract including the budget, server errors, the LOCAL INFILE table, reconnect, escape, transactions, the keyword surface and `show`.

Seventeen text-protocol rows (type mapping incl. BIGINT UNSIGNED/YEAR/BIT/TEXT/VARBINARY, values with NULLs, streaming, row validity, DML snapshots, `lastrowid`, server errors, CALL and `executemultiple`, escape, zero dates, microsecond DATETIME, `DateAndTime`, transactions, show). The `executemultiple`-over-CALL row does not run on 1.6.0, which calls `mysql_num_rows(NULL)` on the CALL's final OK and segfaults (`skip_legacy`).

A complete ER_NEED_REPREPARE (1615) before any result bytes triggers exactly one re-prepare and one re-execute; a statement whose generation predates a reconnect is re-prepared lazily. COM_STMT_CLOSE is finalizer-free: `close!` and a dropped statement park (id, generation) under a per-connection spinlock, and `begin_command!` sends the closes for the current generation before the next command (after draining). `MySQL.load` is generalised to run over either backend.

Newer server-only types need separate evidence. +- Decision — I kept `send_long_data!` and `reset_statement!` in the `MySQL.Native` namespace. I did not expand the package export surface. +- Decision — I accepted vendor-documented legacy NEWDATE framing. I deferred VECTOR because its binary framing is not documented by the sources in scope. +- Decision — I preserved the effective 1.x `Bit`, DecFP, ENUM, temporal, and exception behavior. I kept `Bool` to `MYSQL_TYPE_TINY` as the one directed parameter deviation. +- Decision — I kept all finalizer paths free of transport I/O. Explicit close may wait for the spinlock so it cannot lose an id. +- Validation — The normal and bounds-enabled protocol suites passed after the final code fixes. The later manifest-only commit is not loaded by those commands. +- Validation — The final full package run passed the Connector/C suite, MySQL 8.4, MariaDB 11.4, and every applicable text/binary compatibility row on both live lanes. +- Validation — The final live row verifies prepared CALL result sets and the final OK on both supported server families. The legacy backend remains skipped for its known final-OK crash. +- Validation — `git diff --check fdf23e9..HEAD` passed. Every review commit has the required Codex trailer. +- Validation — I did not consult prohibited GPL/LGPL client implementation code. I did not change the pinned Reseau manifest, edit outside this worktree, or push.

PacketIO gains a 64 KiB read buffer. During the command phase — when the byte stream can only carry this connection's current response — packet reads are served from the buffer, refilled with large all=false partial reads (readbytes! on TCP/TLS); a read of half the buffer or more bypasses it. The connection phase stays byte-exact, so the STARTTLS empty-reader invariant is untouched (replace_transport! now asserts it), and the test-only FaultTransport is never buffered so injected fault byte offsets remain deterministic. A partial read returning zero bytes is the peer closing and faults the session as before. With this and the previous commit the §8.9 scan gates pass: text 0.98x, binary 1.09x, tiny/NULL 0.93x, 64 MiB blob 0.86x, 10k round trips 0.75x plain / 1.00x TLS of Connector/C (mysql:8.4 lane).

Gates: 1M-row text scan, 1M tiny/NULL rows, 10k SELECT 1 round trips (plain and TLS), 100k executemany, and a 64 MiB blob fetch at >= 0.75x C; the 1M-row binary (prepared) scan at >= 1.0x; per-row allocations as above; a >256 MiB streaming result succeeds under default limits while the same result buffered exceeds max_buffered_bytes with a ProtocolError; buffered multi-results individually below but jointly above the budget fail; tiny rows charge their offsets to the budget Round-trip-bound gates (SELECT 1, executemany) sit near a transport latency floor: bare COM_PING — identical bytes, no protocol-layer work — measures ~165us/rt native vs ~130us/rt C, because Reseau's event-loop read wake adds fixed latency over a blocking recv. When such a gate misses its raw ratio, the harness measures both backends' COM_PING floor, asserts the protocol-layer cost net of the floor difference, and records the raw ratio as an explicit @test_skip — never as a pass.

The M5 flake diagnostics caught it red- handed under Pkg.test (all 10,000 stress counters at closes == 0 when the timer won the race against the test's own reap_now! calls, which run in the current world and masked the bug most runs). reap_now! now dispatches transport_close through invokelatest (the reaper is a slow path), and the regression test enqueues a late-defined transport and waits on the timer alone. Production transports (TCP, TLS, FaultTransport) all predate the timer, so this was test-visible only, but a background task closing generic IO should not be pinned to its creation world.

I also rechecked the two prior adversarial-fix rounds. + +## Findings fixed + +| # | Severity | Location | Defect and fix | Regression evidence | +|---:|:---:|---|---|---| +| 1 | Medium | `src/Protocol/commands.jl:296` | Draining an abandoned `COM_STMT_PREPARE` response learned the server statement ID but did not close it. `drain_step!` now parses the full prepare response and sends `COM_STMT_CLOSE` for that ID. (`eb0959f`) | `test/protocol/session_tests.jl:939` verifies the exact close command and ID. | +| 2 | High | `src/Protocol/responses.jl:71` | `parse_ok` accepted malformed payloads for known session-state block types and returned the session to a usable state. Known blocks are now validated while the OK packet is parsed. Unknown block types remain opaque for forward compatibility. (`4475dd4`) | `test/protocol/responses_tests.jl:83` covers truncated, trailing, and malformed known blocks. | +| 3 | High | `src/Protocol/responses.jl:199` | An ERR packet with the SQLSTATE marker and fewer than five state bytes could escape through an unsafe parse path. The parser now rejects the truncated field as `ProtocolError`. (`4475dd4`) | `test/protocol/responses_tests.jl:112` supplies a truncated SQLSTATE. | +| 4 | Medium | `src/Protocol/responses.jl:128` | GTID session state accepted unsupported selectors and malformed length-encoded values. The parser now requires selector `0` and full consumption of one value. (`33ea6b3`) | `test/protocol/responses_tests.jl:88` covers malformed, unsupported, and non-canonical GTID blocks. | +| 5 | Medium | `src/Protocol/responses.jl:120` | An empty `SESSION_TRACK_SYSTEM_VARIABLES` block was accepted even though it cannot contain a name/value pair. The parser now requires at least one complete pair. (`85a36b2`) | `test/protocol/responses_tests.jl:86` covers the empty block. | +| 6 | High | `src/Native/options.jl:121` | On Unix, default protocol selection for an empty host or `localhost` silently selected TCP and discarded an option-file socket. It now selects the local transport and fails clearly because Unix sockets are deferred. Explicit `protocol=:tcp` remains the escape hatch. The analogous Windows pipe rule is preserved. (`8457940`) | `test/protocol/native_tests.jl:180` and `test/protocol/tls_tests.jl:135` cover option files, default hosts, explicit TCP, and strict TLS. | +| 7 | High | `src/Native/load.jl:3` | Native `MySQL.load` did not safely normalize embedded backticks. A later prequoted-name shortcut also trusted malformed quoting. Native identifiers now double embedded backticks, preserve only syntactically valid prequoted identifiers, and normalize unsafe prequoted input. The C backend keeps its 1.x behavior. (`20080d2`, `986ef20`) | `test/protocol/binary_tests.jl:108` covers raw, valid prequoted, qualified, and malformed prequoted identifiers. | +| 8 | High | `src/Native/load.jl:15`, `src/load.jl:87` | Native `debug=true` logged row values, including secrets, and rejected the planned `debug=:values` mode. It now logs statements only for `true`; only `:values` logs row data. (`20080d2`) | `test/protocol/binary_tests.jl:108` asserts the exact logging policy and invalid-mode rejection. | +| 9 | High | `src/Native/reaper.jl:11`, `src/Native/connect.jl:21` | The handle finalizer allocated a queue node/callback on its enqueue path. The reaper now uses an intrusive preallocated entry, a try-lock-only finalizer path, and finalizer re-registration when the lock is busy. Transport close remains outside the global lock. (`bf9133b`) | `test/protocol/native_tests.jl:275` asserts zero enqueue allocations, lock contention behavior, concurrent enqueue, and exactly-once close. | +| 10 | High | `src/Protocol/packets.jl:45`, `src/Protocol/packets.jl:161` | Aggregate response accounting used `Int` and could wrap on 32-bit Julia, which could bypass `max_response_bytes`. It now uses checked-range `UInt64` accounting. (`e7585df`) | `test/protocol/packets_tests.jl:61` crosses `typemax(Int)` and verifies reset on the next command. | +| 11 | Medium | `src/Native/options.jl:416` | `local_infile_handler` accepted only `Function`, which rejected callable structs. Validation now checks `applicable(handler, "")`. (`540a410`) | `test/protocol/native_tests.jl:1` covers a callable functor and a non-callable value. | +| 12 | High | `src/Native/cursor.jl:68` | A foreign task could consume a live streaming cursor and race its connection owner. Streaming cursors now bind to the first consuming task, check the active response token, and reject foreign access. (`d6cf94a`) | `test/protocol/cursor_tests.jl:344` checks foreign row access and iteration. | +| 13 | High | `src/Native/connection.jl:178` | A reconnecting command could try to drain an unread response after its transport was already known closed. It now reconnects before any drain attempt, so no stale transport read occurs. (`d6cf94a`) | `test/protocol/cursor_tests.jl:834` leaves the session in `ROWS`, closes only the transport, and verifies reconnect. | +| 14 | High | `src/Protocol/commands.jl:195`, `src/Protocol/stmt.jl:36` | Result and prepared-statement metadata vectors were sized from the server column count before metadata-byte limits could reject the response. Columns are now appended only after each bounded packet is read and parsed. (`c3c71c4`) | `test/protocol/session_tests.jl:674` verifies that declared metadata cannot force allocation before the byte budget is enforced. | +| 15 | Low | `src/Protocol/auth.jl:42`, `src/Native/binary.jl:45` | The new production tree contained 197 expression-body methods without the required explicit `return`. The native and protocol sources now follow the repository function convention. (`885648f`) | A static full-tree audit found no remaining production violation; all runtime suites stayed green. | +| 16 | Medium | `.github/workflows/ci.yml:13`, `.github/workflows/ci.yml:67` | The clean-room forbidden-reference check and the required 85% native line-coverage threshold were absent. CI now runs both checks. (`dd85d5e`) | `scripts/check_native_cleanroom.jl:1` and `scripts/check_native_coverage.jl:1` are exercised locally; final results are below. | +| 17 | Low | `docs/protocol-notes.md:88`, `docs/protocol-notes.md:221` | The notes still described command-wide I/O timeouts and a per-connection spinlock after those contracts changed. They now describe per-transport-operation timeout re-arming and the `ReentrantLock`/try-lock finalizer design. (`728a68b`) | Documentation was checked against `src/Protocol/packets.jl:41` and `src/Native/connection.jl:37`. | +| 18 | Medium | `test/compat_manifest.jl:523` | The executable compatibility manifest covered result values but omitted most plan section 4.2 rows. It now maps every declared row and runs the surface assertions against both backends on a real server. (`f243d75`) | `test/compat_manifest.jl:655` asserts exact plan-row coverage; the live run passed on both server families. | +| 19 | High | `src/Native/options.jl:345`, `src/Protocol/limits.jl:59`, `src/Protocol/packets.jl:63` | Hostile or oversized integer options could throw `InexactError` or overflow nanosecond deadlines, especially on 32-bit Julia. Options now check `Int` range, timeout seconds have an `Int64` nanosecond cap, and deadline addition saturates. (`6dc35a9`) | `test/protocol/codec_tests.jl:70`, `native_tests.jl:40`, and `packets_tests.jl:70` cover large integers and saturated deadlines. | +| 20 | High | `src/Native/cursor.jl:391` | Advancing a multi-result iterator could drain another task's unconsumed streaming result. The outer iterator now applies the same task-ownership rule as row iteration. (`d4e5529`) | `test/protocol/cursor_tests.jl:492` verifies foreign outer advancement fails without consuming data. | +| 21 | High | `src/Protocol/auth.jl:87`, `src/Protocol/auth.jl:310` | Authentication helpers left SHA intermediates, concatenated password inputs, and sent cleartext/RSA replies in scratch buffers on success and error paths. The code now builds secret buffers directly and wipes every intermediate in `finally` blocks. (`cd8446b`) | `test/protocol/auth_tests.jl:37`, `auth_tests.jl:231`, and `auth_tests.jl:364` verify wiping after success, injected failure, and transport send. | +| 22 | Medium | `src/Protocol/commands.jl:82` | `COM_SET_OPTION` rejected the legal one-byte legacy EOF response. The simple-command reader now accepts the short EOF form while keeping status unchanged. (`25db2de`) | `test/protocol/session_tests.jl:380` covers one-, five-, and seven-byte response forms. | +| 23 | High | `src/Protocol/responses.jl:367`, `src/Native/binary.jl:122` | Binary DATE accepted DATETIME lengths 7 and 11. This could consume a malformed row under the wrong column type. DATE now permits only lengths 0 and 4, and decode repeats the check. (`a3c4e39`) | `test/protocol/binary_tests.jl:229` covers both invalid lengths and the direct decoder. | +| 24 | High | `src/Protocol/columns.jl:47` | The deferred `MYSQL_TYPE_VECTOR` type reached later decode code and could fail outside the documented error contract. It is now rejected at column metadata as `ProtocolError`. (`54bbffa`) | `test/protocol/responses_tests.jl:160` and `cursor_tests.jl:196` cover the parser and live cursor path. | +| 25 | Low | `src/Native/options.jl:382` | `named_pipe=nothing` was rejected even though omitted compatibility keywords use `nothing`. It now means false. (`8ffc698`) | `test/protocol/native_tests.jl:14` covers `nothing` with explicit TCP. | +| 26 | High | `src/Native/statement.jl:164` | Re-prepare could reduce the parameter count and then replay retained long data for a parameter that no longer existed. Invalid retained chunks are now discarded before replay and execution fails locally. (`981a40b`) | `test/protocol/binary_tests.jl:944` simulates a two-parameter statement becoming one parameter and verifies recovery. | +| 27 | High | `src/Native/connect.jl:165`, `src/Native/connect.jl:202` | `init_command` used generic draining for later `LOCAL INFILE` results. It sent an empty upload instead of invoking the configured handler. Init processing now uses the normal bounded upload handler for every result. (`5b3f552`) | `test/protocol/tls_tests.jl:299` verifies a later init result requests and receives the handler payload. | +| 28 | High | `src/Protocol/columns.jl:35` | Invalid UTF-8 in a column name reached `Symbol(col.name)` and escaped as `InvalidCharError`, outside the malformed-stream contract. All six string fields in a column definition are now validated before native metadata use.

This could consume an unnegotiated `metadata_follows` byte silently. -- `src/Protocol/responses.jl:340`, HIGH — Binary row scanning accepted every unknown type as length-encoded and accepted arbitrary temporal lengths. A malicious row could desynchronize all later column spans. -- `src/Native/binary.jl:14`, HIGH — Binary decoders could reach `unsafe_string`, pointer use, and `@inbounds` reads with an invalid caller-controlled span. -- `src/Native/binary.jl:67`, MEDIUM — FLOAT and DOUBLE decoding ignored the measured span width and could read bytes outside the value window. -- `src/Native/binary.jl:84`, MEDIUM — Binary DATE/DATETIME/TIME decoding accepted invalid sign, clock, microsecond, and 838-hour fields. DATE could ignore malformed trailing clock bytes. -- `src/Native/binary.jl:192`, MEDIUM — DecFP and `Bit` parameters used their nominal API types instead of the effective 1.x bind types (`STRING` and `BLOB`). -- `src/Protocol/commands.jl:158`, MEDIUM — COM_STMT_RESET errors and prepared errors received during rows used `Error` instead of the required `StmtError` hierarchy. -- `src/Native/connection.jl:212`, HIGH — Explicit statement close used a nonblocking park and could drop a statement id when the finalizer spinlock was busy. Finalizer parking also allocated queue elements. -- `src/Native/statement.jl:108`, MEDIUM — A successful 1615 re-prepare replaced the statement id without closing the superseded id on the same server generation. -- `src/Native/statement.jl:252`, MEDIUM — Closed-statement and parameter-count errors did not preserve the 1.x exception and message contract. Execute-time `mysql_date_and_time` could also override static prepare metadata. -- `src/Native/cursor.jl:118`, MEDIUM — The buffered-result budget did not charge the binary cursor's retained wire-type table. -- `src/Native/statement.jl:276`, HIGH — Parameter count was checked only before reconnect or 1615 re-prepare. Changed server metadata could produce an invalid execute frame or an indexing failure. -- `src/Native/statement.jl:294`, MEDIUM — Result options were selected before reconnect or 1615 metadata refresh and could apply the wrong temporal mapping. -- `src/Native/connection.jl:113`, HIGH — Connection close did not close the statement-reaper lifecycle. Duplicate or late finalizer parking could retain queue links after the connection was gone. -- `src/Native/statement.jl:301`, HIGH — Authoritative execute-time column definitions did not reliably refresh the Statement cache. Dynamic metadata could become effectively static after its first result. -- `src/Native/statement.jl:301`, MEDIUM — Statement and cursor schema containers were aliased after a metadata refresh, and the cache did not track which temporal option produced its types. -- `src/Native/statement.jl:151`, HIGH — Long-data chunks had no complete driver lifecycle. They were not retained, omitted from inline values, replayed after reconnect/1615, cleared after the first response, or reset safely. -- `src/Protocol/responses.jl:332`, MEDIUM — The legacy `MYSQL_TYPE_NEWDATE` byte form was rejected instead of scanned as length-encoded content and decoded through the preserved String fallback. -- `src/Native/statement.jl:356`, MEDIUM — One-shot `execute(conn, sql, params; mysql_date_and_time=true)` dropped the option when the statement had dynamic execute-time metadata. -- `test/protocol/binary_tests.jl:93`, LOW — M4 unit coverage omitted malformed PREPARE_OK shapes, exact execute framing, span failures, NULL-boundary signatures, reset state, reprepare variants, wrongrow modes, and several parameter families. -- `test/compat_manifest.jl:245`, LOW — The live compatibility manifest omitted the complete parameter family, binary TIME/zero-date/BIT policies, prepared wrongrow, executemany, and prepared CALL multi-results. - -Deferred: -- `src/Protocol/responses.jl:366` — MySQL 9.x `MYSQL_TYPE_VECTOR` is still rejected. The current vendor binary-result documentation does not define its classic-protocol framing, and the required MySQL 8.4/MariaDB 11.4 lanes cannot settle it. Add a documented or capture-gated decoder in the later server-compatibility milestone. -- `src/Protocol/stmt.jl:105` — Server cursors/COM_STMT_FETCH, query attributes, COM_STMT_BULK_EXECUTE, and compression remain deliberate M5/2.x protocol extensions. M4 always sends `CURSOR_TYPE_NO_CURSOR`. -- `src/Native/statement.jl:322` — Prepared CALL multi-results are complete, but special OUT-parameter interpretation and round trips beyond those result sets remain deferred by scope. -- `test/protocol/binary_tests.jl:708` — Section 8.9 scale and performance gates remain for M5: 100k `executemany`, 64 MiB values, allocation limits, and native-versus-C throughput ratios. -- `test/protocol/binary_tests.jl:632` — Section 8.10 still needs the long-running server `Prepared_stmt_count`, fd, heap, and reconnect leak soak. M4 has deterministic and threaded reaper stress coverage. - -Test results: -- `Protocol | 1354 | 1354 | 43.3s` -- `Protocol (--check-bounds=yes) | 1354 | 1354 | 46.0s` -- `MySQL | 1687 | 1687 | 1m36.9s` -- `Testing MySQL tests passed` - -Assumptions / Decisions / Validation: -- Assumption — `fdf23e9` is the accepted M1-M3 boundary. I reviewed only `fdf23e9..HEAD` and used earlier code only to understand an inherited contract. -- Assumption — The external plan, official MySQL/MariaDB protocol documentation, and the local 1.x implementation define Preserve versus Fix. -- Assumption — MySQL 8.4 and MariaDB 11.4 are the required live M4 lanes. Newer server-only types need separate evidence. -- Decision — I kept `send_long_data!` and `reset_statement!` in the `MySQL.Native` namespace. I did not expand the package export surface. -- Decision — I accepted vendor-documented legacy NEWDATE framing. I deferred VECTOR because its binary framing is not documented by the sources in scope. -- Decision — I preserved the effective 1.x `Bit`, DecFP, ENUM, temporal, and exception behavior. I kept `Bool` to `MYSQL_TYPE_TINY` as the one directed parameter deviation. -- Decision — I kept all finalizer paths free of transport I/O. Explicit close may wait for the spinlock so it cannot lose an id. -- Validation — The normal and bounds-enabled protocol suites passed after the final code fixes. The later manifest-only commit is not loaded by those commands. -- Validation — The final full package run passed the Connector/C suite, MySQL 8.4, MariaDB 11.4, and every applicable text/binary compatibility row on both live lanes. -- Validation — The final live row verifies prepared CALL result sets and the final OK on both supported server families. The legacy backend remains skipped for its known final-OK crash. -- Validation — `git diff --check fdf23e9..HEAD` passed.

I also rechecked the two prior adversarial-fix rounds. - -## Findings fixed - -| # | Severity | Location | Defect and fix | Regression evidence | -|---:|:---:|---|---|---| -| 1 | Medium | `src/Protocol/commands.jl:296` | Draining an abandoned `COM_STMT_PREPARE` response learned the server statement ID but did not close it. `drain_step!` now parses the full prepare response and sends `COM_STMT_CLOSE` for that ID. (`eb0959f`) | `test/protocol/session_tests.jl:939` verifies the exact close command and ID. | -| 2 | High | `src/Protocol/responses.jl:71` | `parse_ok` accepted malformed payloads for known session-state block types and returned the session to a usable state. Known blocks are now validated while the OK packet is parsed. Unknown block types remain opaque for forward compatibility. (`4475dd4`) | `test/protocol/responses_tests.jl:83` covers truncated, trailing, and malformed known blocks. | -| 3 | High | `src/Protocol/responses.jl:199` | An ERR packet with the SQLSTATE marker and fewer than five state bytes could escape through an unsafe parse path. The parser now rejects the truncated field as `ProtocolError`. (`4475dd4`) | `test/protocol/responses_tests.jl:112` supplies a truncated SQLSTATE. | -| 4 | Medium | `src/Protocol/responses.jl:128` | GTID session state accepted unsupported selectors and malformed length-encoded values. The parser now requires selector `0` and full consumption of one value. (`33ea6b3`) | `test/protocol/responses_tests.jl:88` covers malformed, unsupported, and non-canonical GTID blocks. | -| 5 | Medium | `src/Protocol/responses.jl:120` | An empty `SESSION_TRACK_SYSTEM_VARIABLES` block was accepted even though it cannot contain a name/value pair. The parser now requires at least one complete pair. (`85a36b2`) | `test/protocol/responses_tests.jl:86` covers the empty block. | -| 6 | High | `src/Native/options.jl:121` | On Unix, default protocol selection for an empty host or `localhost` silently selected TCP and discarded an option-file socket. It now selects the local transport and fails clearly because Unix sockets are deferred. Explicit `protocol=:tcp` remains the escape hatch. The analogous Windows pipe rule is preserved. (`8457940`) | `test/protocol/native_tests.jl:180` and `test/protocol/tls_tests.jl:135` cover option files, default hosts, explicit TCP, and strict TLS. | -| 7 | High | `src/Native/load.jl:3` | Native `MySQL.load` did not safely normalize embedded backticks. A later prequoted-name shortcut also trusted malformed quoting. Native identifiers now double embedded backticks, preserve only syntactically valid prequoted identifiers, and normalize unsafe prequoted input. The C backend keeps its 1.x behavior. (`20080d2`, `986ef20`) | `test/protocol/binary_tests.jl:108` covers raw, valid prequoted, qualified, and malformed prequoted identifiers. | -| 8 | High | `src/Native/load.jl:15`, `src/load.jl:87` | Native `debug=true` logged row values, including secrets, and rejected the planned `debug=:values` mode. It now logs statements only for `true`; only `:values` logs row data. (`20080d2`) | `test/protocol/binary_tests.jl:108` asserts the exact logging policy and invalid-mode rejection. | -| 9 | High | `src/Native/reaper.jl:11`, `src/Native/connect.jl:21` | The handle finalizer allocated a queue node/callback on its enqueue path. The reaper now uses an intrusive preallocated entry, a try-lock-only finalizer path, and finalizer re-registration when the lock is busy. Transport close remains outside the global lock. (`bf9133b`) | `test/protocol/native_tests.jl:275` asserts zero enqueue allocations, lock contention behavior, concurrent enqueue, and exactly-once close. | -| 10 | High | `src/Protocol/packets.jl:45`, `src/Protocol/packets.jl:161` | Aggregate response accounting used `Int` and could wrap on 32-bit Julia, which could bypass `max_response_bytes`. It now uses checked-range `UInt64` accounting. (`e7585df`) | `test/protocol/packets_tests.jl:61` crosses `typemax(Int)` and verifies reset on the next command. | -| 11 | Medium | `src/Native/options.jl:416` | `local_infile_handler` accepted only `Function`, which rejected callable structs. Validation now checks `applicable(handler, "")`. (`540a410`) | `test/protocol/native_tests.jl:1` covers a callable functor and a non-callable value. | -| 12 | High | `src/Native/cursor.jl:68` | A foreign task could consume a live streaming cursor and race its connection owner. Streaming cursors now bind to the first consuming task, check the active response token, and reject foreign access. (`d6cf94a`) | `test/protocol/cursor_tests.jl:344` checks foreign row access and iteration. | -| 13 | High | `src/Native/connection.jl:178` | A reconnecting command could try to drain an unread response after its transport was already known closed. It now reconnects before any drain attempt, so no stale transport read occurs. (`d6cf94a`) | `test/protocol/cursor_tests.jl:834` leaves the session in `ROWS`, closes only the transport, and verifies reconnect. | -| 14 | High | `src/Protocol/commands.jl:195`, `src/Protocol/stmt.jl:36` | Result and prepared-statement metadata vectors were sized from the server column count before metadata-byte limits could reject the response. Columns are now appended only after each bounded packet is read and parsed. (`c3c71c4`) | `test/protocol/session_tests.jl:674` verifies that declared metadata cannot force allocation before the byte budget is enforced. | -| 15 | Low | `src/Protocol/auth.jl:42`, `src/Native/binary.jl:45` | The new production tree contained 197 expression-body methods without the required explicit `return`. The native and protocol sources now follow the repository function convention. (`885648f`) | A static full-tree audit found no remaining production violation; all runtime suites stayed green. | -| 16 | Medium | `.github/workflows/ci.yml:13`, `.github/workflows/ci.yml:67` | The clean-room forbidden-reference check and the required 85% native line-coverage threshold were absent. CI now runs both checks. (`dd85d5e`) | `scripts/check_native_cleanroom.jl:1` and `scripts/check_native_coverage.jl:1` are exercised locally; final results are below. | -| 17 | Low | `docs/protocol-notes.md:88`, `docs/protocol-notes.md:221` | The notes still described command-wide I/O timeouts and a per-connection spinlock after those contracts changed. They now describe per-transport-operation timeout re-arming and the `ReentrantLock`/try-lock finalizer design. (`728a68b`) | Documentation was checked against `src/Protocol/packets.jl:41` and `src/Native/connection.jl:37`. | -| 18 | Medium | `test/compat_manifest.jl:523` | The executable compatibility manifest covered result values but omitted most plan section 4.2 rows. It now maps every declared row and runs the surface assertions against both backends on a real server. (`f243d75`) | `test/compat_manifest.jl:655` asserts exact plan-row coverage; the live run passed on both server families. | -| 19 | High | `src/Native/options.jl:345`, `src/Protocol/limits.jl:59`, `src/Protocol/packets.jl:63` | Hostile or oversized integer options could throw `InexactError` or overflow nanosecond deadlines, especially on 32-bit Julia. Options now check `Int` range, timeout seconds have an `Int64` nanosecond cap, and deadline addition saturates. (`6dc35a9`) | `test/protocol/codec_tests.jl:70`, `native_tests.jl:40`, and `packets_tests.jl:70` cover large integers and saturated deadlines. | -| 20 | High | `src/Native/cursor.jl:391` | Advancing a multi-result iterator could drain another task's unconsumed streaming result. The outer iterator now applies the same task-ownership rule as row iteration. (`d4e5529`) | `test/protocol/cursor_tests.jl:492` verifies foreign outer advancement fails without consuming data. | -| 21 | High | `src/Protocol/auth.jl:87`, `src/Protocol/auth.jl:310` | Authentication helpers left SHA intermediates, concatenated password inputs, and sent cleartext/RSA replies in scratch buffers on success and error paths. The code now builds secret buffers directly and wipes every intermediate in `finally` blocks. (`cd8446b`) | `test/protocol/auth_tests.jl:37`, `auth_tests.jl:231`, and `auth_tests.jl:364` verify wiping after success, injected failure, and transport send. | -| 22 | Medium | `src/Protocol/commands.jl:82` | `COM_SET_OPTION` rejected the legal one-byte legacy EOF response. The simple-command reader now accepts the short EOF form while keeping status unchanged. (`25db2de`) | `test/protocol/session_tests.jl:380` covers one-, five-, and seven-byte response forms. | -| 23 | High | `src/Protocol/responses.jl:367`, `src/Native/binary.jl:122` | Binary DATE accepted DATETIME lengths 7 and 11. This could consume a malformed row under the wrong column type. DATE now permits only lengths 0 and 4, and decode repeats the check. (`a3c4e39`) | `test/protocol/binary_tests.jl:229` covers both invalid lengths and the direct decoder. | -| 24 | High | `src/Protocol/columns.jl:47` | The deferred `MYSQL_TYPE_VECTOR` type reached later decode code and could fail outside the documented error contract. It is now rejected at column metadata as `ProtocolError`. (`54bbffa`) | `test/protocol/responses_tests.jl:160` and `cursor_tests.jl:196` cover the parser and live cursor path. | -| 25 | Low | `src/Native/options.jl:382` | `named_pipe=nothing` was rejected even though omitted compatibility keywords use `nothing`. It now means false. (`8ffc698`) | `test/protocol/native_tests.jl:14` covers `nothing` with explicit TCP. | -| 26 | High | `src/Native/statement.jl:164` | Re-prepare could reduce the parameter count and then replay retained long data for a parameter that no longer existed. Invalid retained chunks are now discarded before replay and execution fails locally. (`981a40b`) | `test/protocol/binary_tests.jl:944` simulates a two-parameter statement becoming one parameter and verifies recovery. | -| 27 | High | `src/Native/connect.jl:165`, `src/Native/connect.jl:202` | `init_command` used generic draining for later `LOCAL INFILE` results. It sent an empty upload instead of invoking the configured handler. Init processing now uses the normal bounded upload handler for every result. (`5b3f552`) | `test/protocol/tls_tests.jl:299` verifies a later init result requests and receives the handler payload. | -| 28 | High | `src/Protocol/columns.jl:35` | Invalid UTF-8 in a column name reached `Symbol(col.name)` and escaped as `InvalidCharError`, outside the malformed-stream contract. All six string fields in a column definition are now validated before native metadata use. (`e93a9a7`) | `test/protocol/cursor_tests.jl:211` sends an invalid name and verifies `ProtocolError` plus connection fault. | -| 29 | Medium | `test/runtests.jl:36`, `test/runtests.jl:126` | The recent CI policy set `MYSQL_PERF_GATES=0` and skipped the entire Docker §8.9 block, although the contract disabled only unstable timing ratios. Correctness, limit, and allocation gates now always run when Docker is available; the setting controls only timing. (`95b582d`) | `test/runtests.jl:110` covers CI default, explicit timing opt-in, local default, and no-Docker plans. The final full run executed every recovered gate. | - -## Validation - -- Baseline before review fixes: - - Serverless, Julia 1.12, 4 threads: 1443/1443. - - Serverless, Julia 1.12, 1 thread: 1443/1443. -- Final serverless suite at code head `95b582d`: - - `julia --project=. -t 4 --startup-file=no -e 'include("test/protocol/runtests.jl")'`: 1515/1515 in 1m18.2s. - - `julia --project=. -t 1 --startup-file=no -e 'include("test/protocol/runtests.jl")'`: 1515/1515 in 1m21.1s. - - Julia 1.10.11 clean compatibility environment: 1515/1515 in 57.9s. -- Malformed-stream fuzzing: - - Final-head deterministic worker: 1,000,000 cases, seeds 1,000,000 through 1,999,999, zero violations. -- Acceptance scripts: - - Native line coverage: 2719/2787 executable lines, 97.56%. - - Clean-room scan: 28 source files, zero forbidden references. -- Full gate: - - `CI=true julia --project=. --startup-file=no -e 'using Pkg; Pkg.test()'`: 2045/2045 in 4m29.0s with `--check-bounds=yes`. - - The full gate ran native live lanes on `mysql:8.4` and `mariadb:11.4`, the two-backend compatibility manifest, the lifecycle soak, and the stable Connector/C tests. - - The same run executed the 1M-row text, binary, and tiny/NULL correctness and allocation gates, 100k `executemany`, the 64 MiB blob gate, and the >256 MiB streaming/buffer-limit gates. - - Allocation results were 2.000 per row for text, 2.000 per row for binary, and 1.000 per row for tiny/NULL, at their respective limits of 2, 2, and 1. - - CI intentionally skipped only the timing ratios.

Known block types are strict. -- I treated explicit `protocol=:tcp` as the supported escape hatch from the deferred local transport selected for an empty host or `localhost`. -- I did not change Reseau.

I used imperative subjects for every new review commit. - -## Deferred / noted for the human - -- External interoperability captures, a Windows named-pipe implementation, Windows ARM64 execution, and the long preview soak remain the explicitly deferred items listed in `docs/protocol-notes.md`. I did not turn those declared future gates into code changes. -- The registered-package propagation delay for Reseau 1.4.1 is external state. I did not lower compat because 1.4.1 contains the required TLS 1.3 client-certificate fix. - -VERDICT: CLEAN From ace0bce42cdc07d5380904b4330c559ac65b5391 Mon Sep 17 00:00:00 2001 From: Jacob Quinn Date: Mon, 24 Aug 2026 08:53:08 -0600 Subject: [PATCH 157/162] =?UTF-8?q?feat!:=20MySQL.jl=202.0=20=E2=80=94=20t?= =?UTF-8?q?he=20native=20wire=20protocol=20is=20the=20only=20backend?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Removes MariaDB Connector/C entirely: src/api (3.5k lines of C wrappers, enums, and handle lifetimes), the C driver layer (execute/prepare/load), and the MariaDB_Connector_C_jll / Libdl dependencies. The former MySQL.Native driver layer is promoted to the package root: MySQL.Connection, Statement, Cursor{binary,buffered} (TextCursor / BinaryCursor, TextRow / BinaryRow), MySQL.ping / escape / escape_identifier / send_long_data! / reset_statement! / ConnectOptions. The value types move to the top level (MySQL.Bit, MySQL.DateAndTime, MySQL.juliatype) and the protocol errors get their 1.x names back as aliases: MySQL.Error / MySQL.StmtError / MySQL.MySQLError. Deliberate 2.0 cleanups beyond the documented native-backend fixes: only a leading mysql:// host prefix is stripped, port=0 means 3306, conn.port is an Int, enum-valued options are Symbols, option values are validated against closed type sets, and lastrowid on a SELECT cursor reports 0. A bare scalar remains accepted as single-parameter params. The test suite follows: the dual-backend compat manifest becomes a native-only golden behavior manifest (25 preserve-row goldens captured against mysql:8.4 from the final dual-backend runs), the §8.9 gates keep correctness/allocation/limit assertions and print a timing report (the C-ratio gates retire; see bench/), and the 1.x integration suite runs against the native client. Internals are --trim=safe-clean for juliac: concrete Transport and auth plugin unions (which also lets the reaper drop its invokelatest — no transport close method can postdate the timer's world), typed option extraction, Val-parametrized cursor construction, named runtime callbacks with registered entrypoints, and the user-supplied local-infile handler routed through the runtime's generic-dispatch entry. Docs: the migration guide is rewritten as a 1.x → 2.0 upgrade guide (API mapping table, upgrade checklist, behavior tables, option value types, static-compilation notes).

If you must save the value for later, be sure to call mysql_insert_id() immediately after the statement that generates the value. - -The value of mysql_insert_id() is affected only by statements issued within the current client connection. It is not affected by statements issued by other clients. - -The LAST_INSERT_ID() SQL function will contain the value of the first automatically generated value that was successfully inserted. LAST_INSERT_ID() is not reset between statements because the value of that function is maintained in the server. Another difference from mysql_insert_id() is that LAST_INSERT_ID() is not updated if you set an AUTO_INCREMENT column to a specific nonspecial value. See Section 12.15, “Information Functions”. - -mysql_insert_id() returns 0 following a CALL statement for a stored procedure that generates an AUTO_INCREMENT value because in this case mysql_insert_id() applies to CALL and not the statement within the procedure. Within the procedure, you can use LAST_INSERT_ID() at the SQL level to obtain the AUTO_INCREMENT value. - -The reason for the differences between LAST_INSERT_ID() and mysql_insert_id() is that LAST_INSERT_ID() is made easy to use in scripts while mysql_insert_id() tries to provide more exact information about what happens to the AUTO_INCREMENT column. -"""=# -function insertid(mysql::MYSQL) - return mysql_insert_id(mysql.ptr) -end - -#=""" -Description -This function is used when you execute multiple statements specified as a single statement string, or when you execute CALL statements, which can return multiple result sets. - -mysql_more_results() true if more results exist from the currently executed statement, in which case the application must call mysql_next_result() to fetch the results. - -Return Values -TRUE (1) if more results exist.

This means that you can call mysql_store_result(), mysql_warning_count(), mysql_affected_rows(), and so forth. - -If your program uses CALL statements to execute stored procedures, the CLIENT_MULTI_RESULTS flag must be enabled. This is because each CALL returns a result to indicate the call status, in addition to any result sets that might be returned by statements executed within the procedure.

CLIENT_MULTI_RESULTS is enabled by default. - -It is also possible to test whether there are more results by calling mysql_more_results(). However, this function does not change the connection state, so if it returns true, you must still call mysql_next_result() to advance to the next result. - -For an example that shows how to use mysql_next_result(), see Section 28.6.22, “C API Multiple Statement Execution Support”. - -Return Values -Return Value Description -0 Successful and there are more results --1 Successful and there are no more results ->0 An error occurred -"""=# -function nextresult(mysql::MYSQL) - ret = mysql_next_result(mysql.ptr) - return ret == -1 ? nothing : ret == 0 ? ret : throw(Error(mysql)) -end - -#=""" -Description -Returns the number of columns in a result set. - -You can get the number of columns either from a pointer to a result set or to a connection handler.

In this case, you can call mysql_field_count() to determine whether mysql_store_result() should have produced a nonempty result. This enables the client program to take proper action without knowing whether the query was a SELECT (or SELECT-like) statement.

The meaning of MYSQL_OPT_COMPRESS depends on whether MYSQL_OPT_COMPRESSION_ALGORITHMS is specified: - -When MYSQL_OPT_COMPRESSION_ALGORITHMS is not specified, enabling MYSQL_OPT_COMPRESS is equivalent to specifying a client-side algorithm set of zlib,uncompressed. - -When MYSQL_OPT_COMPRESSION_ALGORITHMS is specified, enabling MYSQL_OPT_COMPRESS is equivalent to specifying an algorithm set of zlib and the full client-side algorithm set is the union of zlib plus the algorithms specified by MYSQL_OPT_COMPRESSION_ALGORITHMS. For example, with MYSQL_OPT_COMPRESS enabled and MYSQL_OPT_COMPRESSION_ALGORITHMS set to zlib,zstd, the permitted-algorithm set is zlib plus zlib,zstd; that is, zlib,zstd. With MYSQL_OPT_COMPRESS enabled and MYSQL_OPT_COMPRESSION_ALGORITHMS set to zstd,uncompressed, the permitted-algorithm set is zlib plus zstd,uncompressed; that is, zlib,zstd,uncompressed. - -As of MySQL 8.0.18, MYSQL_OPT_COMPRESS is deprecated.

This option applies to clients that authenticate with the caching_sha2_password authentication plugin. For that plugin, the server does not send the public key unless requested. This option is ignored for accounts that do not authenticate with that plugin. It is also ignored if RSA-based password exchange is not used, as is the case when the client connects to the server using a secure connection. - -If MYSQL_SERVER_PUBLIC_KEY is given and specifies a valid public key file, it takes precedence over MYSQL_OPT_GET_SERVER_PUBLIC_KEY. - -For information about the caching_sha2_password plugin, see Section 6.4.1.2, “Caching SHA-2 Pluggable Authentication”. - -MYSQL_OPT_LOCAL_INFILE (argument type: optional pointer to unsigned int) - -This option affects client-side LOCAL capability for LOAD DATA operations. By default, LOCAL capability is determined by the default compiled into the MySQL client library (see Section 13.2.7, “LOAD DATA Statement”). To control this capability explicitly, invoke mysql_options() to set the MYSQL_OPT_LOCAL_INFILE option: - -LOCAL is disabled if the pointer points to an unsigned int that has a zero value. - -LOCAL is enabled if no pointer is given or if the pointer points to an unsigned int that has a nonzero value. - -Successful use of a LOCAL load operation by a client also requires that the server permits it. - -MYSQL_OPT_MAX_ALLOWED_PACKET (argument: unsigned long *) - -This option sets the max_allowed_packet system variable. If the mysql argument is non-NULL, the call sets the session system variable value for that session. If mysql is NULL, the call sets the global system variable value. - -MYSQL_OPT_NAMED_PIPE (argument: not used) - -Use a named pipe to connect to the MySQL server on Windows, if the server permits named-pipe connections. - -MYSQL_OPT_NET_BUFFER_LENGTH (argument: unsigned long *) - -This option sets the net_buffer_length system variable. If the mysql argument is non-NULL, the call sets the session system variable value for that session. If mysql is NULL, the call sets the global system variable value. - -MYSQL_OPT_OPTIONAL_RESULTSET_METADATA (argument type: bool *) - -This flag makes result set metadata optional. It is an alternative way of setting the CLIENT_OPTIONAL_RESULTSET_METADATA connection flag for the mysql_real_connect() function. For details about managing result set metadata transfer, see Section 28.6.26, “C API Optional Result Set Metadata”. - -MYSQL_OPT_PROTOCOL (argument type: unsigned int *) - -Type of protocol to use. Specify one of the enum values of mysql_protocol_type defined in mysql.h. - -MYSQL_OPT_READ_TIMEOUT (argument type: unsigned int *) - -The timeout in seconds for each attempt to read from the server. There are retries if necessary, so the total effective timeout value is three times the option value. You can set the value so that a lost connection can be detected earlier than the TCP/IP Close_Wait_Timeout value of 10 minutes. - -MYSQL_OPT_RECONNECT (argument type: bool *) - -Enable or disable automatic reconnection to the server if the connection is found to have been lost. Reconnect is off by default; this option provides a way to set reconnection behavior explicitly. See Section 28.6.27, “C API Automatic Reconnection Control”. - -MYSQL_OPT_RETRY_COUNT (argument type: unsigned int *) - -The retry count for I/O-related system calls that are interrupted while connecting to the server or communicating with it. If this option is not specified, the default value is 1 (1 retry if the initial call is interrupted for 2 tries total). - -This option can be used only by clients that link against a C client library compiled with NDB Cluster support. - -MYSQL_OPT_SSL_CA (argument type: char *) - -The path name of the Certificate Authority (CA) certificate file.

The MYSQL_OPT_SSL_FIPS_MODE option differs from other MYSQL_OPT_SSL_xxx options in that it is not used to establish encrypted connections, but rather to affect which cryptographic operations are permitted. See Section 6.5, “FIPS Support”. - -Permitted option values are SSL_FIPS_MODE_OFF, SSL_FIPS_MODE_ON, and SSL_FIPS_MODE_STRICT. - -Note -If the OpenSSL FIPS Object Module is not available, the only permitted value for MYSQL_OPT_SSL_FIPS_MODE is SSL_FIPS_MODE_OFF. In this case, setting MYSQL_OPT_SSL_FIPS_MODE to SSL_FIPS_MODE_ON or SSL_FIPS_MODE_STRICT causes the client to produce a warning at startup and to operate in non-FIPS mode. - -MYSQL_OPT_SSL_KEY (argument type: char *) - -The path name of the client private key file. - -MYSQL_OPT_SSL_MODE (argument type: unsigned int *) - -The security state to use for the connection to the server: SSL_MODE_DISABLED, SSL_MODE_PREFERRED, SSL_MODE_REQUIRED, SSL_MODE_VERIFY_CA, SSL_MODE_VERIFY_IDENTITY.

There is a retry if necessary, so the total effective timeout value is two times the option value. - -MYSQL_OPT_ZSTD_COMPRESSION_LEVEL (argument type: unsigned int *) - -The compression level to use for connections to the server that use the zstd compression algorithm. The permitted levels are from 1 to 22, with larger values indicating increasing levels of compression. If this option is not specified, the default zstd compression level is 3. The compression level setting has no effect on connections that do not use zstd compression. - -For more information, see Section 4.2.6, “Connection Compression Control”. - -This option was added in MySQL 8.0.18. - -MYSQL_PLUGIN_DIR (argument type: char *) - -The directory in which to look for client plugins. - -MYSQL_READ_DEFAULT_FILE (argument type: char *) - -Read options from the named option file instead of from my.cnf. - -MYSQL_READ_DEFAULT_GROUP (argument type: char *) - -Read options from the named group from my.cnf or the file specified with MYSQL_READ_DEFAULT_FILE. - -MYSQL_REPORT_DATA_TRUNCATION (argument type: bool *) - -Enable or disable reporting of data truncation errors for prepared statements using the error member of MYSQL_BIND structures. (Default: enabled.) - -MYSQL_SERVER_PUBLIC_KEY (argument type: char *) - -The path name of the file containing a client-side copy of the public key required by the server for RSA key pair-based password exchange.

Before calling mysql_real_connect(), call mysql_init() to initialize the MYSQL structure. You can change a lot of connect options with the mysql_options() call. See Section 28.6.6.50, “mysql_options()”. - -The value of host may be either a host name or an IP address. The client attempts to connect as follows: - -If host is NULL or the string "localhost", a connection to the local host is assumed: - -On Windows, the client connects using a shared-memory connection, if the server has shared-memory connections enabled. - -On Unix, the client connects using a Unix socket file. The unix_socket parameter or the MYSQL_UNIX_PORT environment variable may be used to specify the socket name. - -On Windows, if host is ".", or TCP/IP is not enabled and no unix_socket is specified or the host is empty, the client connects using a named pipe, if the server has named-pipe connections enabled. If named-pipe connections are not enabled, an error occurs. - -Otherwise, TCP/IP is used. - -You can also influence the type of connection to use with the MYSQL_OPT_PROTOCOL or MYSQL_OPT_NAMED_PIPE options to mysql_options(). The type of connection must be supported by the server. - -The user parameter contains the user's MySQL login ID. If user is NULL or the empty string "", the current user is assumed. Under Unix, this is the current login name. Under Windows ODBC, the current user name must be specified explicitly. See the Connector/ODBC section of Chapter 28, Connectors and APIs. - -The passwd parameter contains the password for user. If passwd is NULL, only entries in the user table for the user that have a blank (empty) password field are checked for a match. This enables the database administrator to set up the MySQL privilege system in such a way that users get different privileges depending on whether they have specified a password. - -Note -Do not attempt to encrypt the password before calling mysql_real_connect(); password encryption is handled automatically by the client API. - -The user and passwd parameters use whatever character set has been configured for the MYSQL object. By default, this is utf8mb4, but can be changed by calling mysql_options(mysql, MYSQL_SET_CHARSET_NAME, "charset_name") prior to connecting. - -db is the database name. If db is not NULL, the connection sets the default database to this value. - -If port is not 0, the value is used as the port number for the TCP/IP connection. Note that the host parameter determines the type of the connection. - -If unix_socket is not NULL, the string specifies the socket or named pipe to use. Note that the host parameter determines the type of the connection. - -The value of client_flag is usually 0, but can be set to a combination of the following flags to enable certain features: - -CAN_HANDLE_EXPIRED_PASSWORDS: The client can handle expired passwords. For more information, see Section 6.2.16, “Server Handling of Expired Passwords”. - -CLIENT_COMPRESS: Use compression in the client/server protocol. - -CLIENT_FOUND_ROWS: Return the number of found (matched) rows, not the number of changed rows. - -CLIENT_IGNORE_SIGPIPE: Prevents the client library from installing a SIGPIPE signal handler. This can be used to avoid conflicts with a handler that the application has already installed. - -CLIENT_IGNORE_SPACE: Permit spaces after function names. Makes all functions names reserved words. - -CLIENT_INTERACTIVE: Permit interactive_timeout seconds of inactivity (rather than wait_timeout seconds) before closing the connection. The client's session wait_timeout variable is set to the value of the session interactive_timeout variable. - -CLIENT_LOCAL_FILES: Enable LOAD DATA LOCAL handling. - -CLIENT_MULTI_RESULTS: Tell the server that the client can handle multiple result sets from multiple-statement executions or stored procedures. This flag is automatically enabled if CLIENT_MULTI_STATEMENTS is enabled. See the note following this table for more information about this flag. - -CLIENT_MULTI_STATEMENTS: Tell the server that the client may send multiple statements in a single string (separated by ; characters). If this flag is not set, multiple-statement execution is disabled. See the note following this table for more information about this flag. - -CLIENT_NO_SCHEMA Do not permit db_name.tbl_name.col_name syntax. This is for ODBC. It causes the parser to generate an error if you use that syntax, which is useful for trapping bugs in some ODBC programs. - -CLIENT_ODBC: Unused. - -CLIENT_OPTIONAL_RESULTSET_METADATA: This flag makes result set metadata optional. Suppression of metadata transfer can improve performance, particularly for sessions that execute many queries that return few rows each. For details about managing result set metadata transfer, see Section 28.6.26, “C API Optional Result Set Metadata”. - -CLIENT_SSL: Use SSL (encrypted protocol). Do not set this option within an application program; it is set internally in the client library. Instead, use mysql_options() or mysql_ssl_set() before calling mysql_real_connect(). - -CLIENT_REMEMBER_OPTIONS Remember options specified by calls to mysql_options(). Without this option, if mysql_real_connect() fails, you must repeat the mysql_options() calls before trying to connect again. With this option, the mysql_options() calls need not be repeated. - -If your program uses CALL statements to execute stored procedures, the CLIENT_MULTI_RESULTS flag must be enabled. This is because each CALL returns a result to indicate the call status, in addition to any result sets that might be returned by statements executed within the procedure. Because CALL can return multiple results, process them using a loop that calls mysql_next_result() to determine whether there are more results. - -CLIENT_MULTI_RESULTS can be enabled when you call mysql_real_connect(), either explicitly by passing the CLIENT_MULTI_RESULTS flag itself, or implicitly by passing CLIENT_MULTI_STATEMENTS (which also enables CLIENT_MULTI_RESULTS). CLIENT_MULTI_RESULTS is enabled by default. - -If you enable CLIENT_MULTI_STATEMENTS or CLIENT_MULTI_RESULTS, process the result for every call to mysql_query() or mysql_real_query() by using a loop that calls mysql_next_result() to determine whether there are more results. For an example, see Section 28.6.22, “C API Multiple Statement Execution Support”. - -For some parameters, it is possible to have the value taken from an option file rather than from an explicit value in the mysql_real_connect() call. To do this, call mysql_options() with the MYSQL_READ_DEFAULT_FILE or MYSQL_READ_DEFAULT_GROUP option before calling mysql_real_connect(). Then, in the mysql_real_connect() call, specify the “no-value” value for each parameter to be read from an option file: - -For host, specify a value of NULL or the empty string (""). - -For user, specify a value of NULL or the empty string. - -For passwd, specify a value of NULL. (For the password, a value of the empty string in the mysql_real_connect() call cannot be overridden in an option file, because the empty string indicates explicitly that the MySQL account must have an empty password.) - -For db, specify a value of NULL or the empty string. - -For port, specify a value of 0. - -For unix_socket, specify a value of NULL. - -If no value is found in an option file for a parameter, its default value is used as indicated in the descriptions given earlier in this section. - -Return Values -A MYSQL* connection handler if the connection was successful, NULL if the connection was unsuccessful.

The mysql argument must be a valid connection handler. Any unused SSL arguments may be given as NULL. - -If used, mysql_ssl_set() must be called before mysql_real_connect(). mysql_ssl_set() does nothing unless SSL support is enabled in the client library. - -It is optional to call mysql_ssl_set() to obtain an encrypted connection because by default, MySQL programs attempt to connect using encryption if the server supports encrypted connections, falling back to an unencrypted connection if an encrypted connection cannot be established (see Section 6.3.1, “Configuring MySQL to Use Encrypted Connections”). mysql_ssl_set() may be useful to applications that must specify particular certificate and key files, encryption ciphers, and so forth. - -mysql_ssl_set() specifies SSL information such as certificate and key files for establishing an encrypted connection if such connections are available, but does not enforce any requirement that the connection obtained be encrypted. To require an encrypted connection, use the technique described in Section 28.6.21, “C API Encrypted Connection Support”. - -For additional security relative to that provided by the default encryption, clients can supply a CA certificate matching the one used by the server and enable host name identity verification. In this way, the server and client place their trust in the same CA certificate and the client verifies that the host to which it connected is the one intended. For details, see Section 28.6.21, “C API Encrypted Connection Support”. - -mysql_ssl_set() is a convenience function that is essentially equivalent to this set of mysql_options() calls: - -mysql_options(mysql, MYSQL_OPT_SSL_KEY, key); -mysql_options(mysql, MYSQL_OPT_SSL_CERT, cert); -mysql_options(mysql, MYSQL_OPT_SSL_CA, ca); -mysql_options(mysql, MYSQL_OPT_SSL_CAPATH, capath); -mysql_options(mysql, MYSQL_OPT_SSL_CIPHER, cipher); -Because of that equivalence, applications can, instead of calling mysql_ssl_set(), call mysql_options() directly, omitting calls for those options for which the option value is NULL. Moreover, mysql_options() offers encrypted-connection options not available using mysql_ssl_set(), such as MYSQL_OPT_SSL_MODE to specify the security state of the connection, and MYSQL_OPT_TLS_VERSION to specify the protocols the client permits for encrypted connections. - -Arguments: - -mysql: The connection handler returned from mysql_init(). - -key: The path name of the client private key file. - -cert: The path name of the client public key certificate file. - -ca: The path name of the Certificate Authority (CA) certificate file.

You can detect whether the statement has a result set by checking whether mysql_store_result() returns a nonzero value (more about this later). - -If you enable multiple-statement support, you should retrieve results from calls to mysql_query() or mysql_real_query() by using a loop that calls mysql_next_result() to determine whether there are more results. For an example, see Section 28.6.22, “C API Multiple Statement Execution Support”. - -If you want to know whether a statement should return a result set, you can use mysql_field_count() to check for this.

Instead, each row must be retrieved individually by making calls to mysql_fetch_row(). This reads the result of a query directly from the server without storing it in a temporary table or local buffer, which is somewhat faster and uses much less memory than mysql_store_result(). The client allocates memory only for the current row and a communication buffer that may grow up to max_allowed_packet bytes. - -On the other hand, you should not use mysql_use_result() for locking reads if you are doing a lot of processing for each row on the client side, or if the output is sent to a screen on which the user may type a ^S (stop scroll). This ties up the server and prevent other threads from updating any tables from which the data is being fetched. - -When using mysql_use_result(), you must execute mysql_fetch_row() until a NULL value is returned, otherwise, the unfetched rows are returned as part of the result set for your next query.

charset=UTF-8 Content-Transfer-Encoding: 8bit test/mysql_trim_workload.jl drives the main entrypoints — connect (handshake, auth, charset bootstrap), buffered and streaming text execute, prepared statements, one-shot parameterized execute, ping, escape, close — against a scripted in-process MySQL server on a loopback Reseau listener, consuming rows through the schema-typed accessor. The harness (test/trim_compile_tests.jl, wired into Pkg.test on Julia 1.12+) builds it with juliac --trim=safe in a temp environment, requires zero verifier errors and warnings, runs the executable, and asserts its output; MYSQL_RUN_TRIM_TESTS=0 skips it. Known trim caveats (documented in the migration guide): task bodies must be entrypoint-registered named functions, and Reseau's deadline-armed waits (connect/read/write timeouts) hang in trimmed builds, so the workload connects without timeouts.
