From 847292810281968e73309c9bd0566ca05c2080db Mon Sep 17 00:00:00 2001 From: CharlesKWON Date: Sun, 17 May 2026 12:55:41 +0900 Subject: [PATCH] =?UTF-8?q?feat(pgserver):=20Phase=204=20=E2=80=94=20Exten?= =?UTF-8?q?ded=20Protocol=20(Parse/Bind/Execute)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit pgx and most drivers default to PostgreSQL's Extended Protocol (named prepared statements). Phase 2 only handled Simple Query, so every pgx caller had to force `QueryExecModeSimpleProtocol` — unworkable for a production deployment. This commit lands the full Parse → Bind → Describe → Execute → Sync state machine, enough that pgx (and any other libpq-protocol-v3 client) works without any client-side knobs. Implementation lives in `hbrtl/pgserver/extended.go`: * Per-session caches `stmts map[string]*preparedStmt` and `portals map[string]*portal`, lazily allocated on first use. Stored as fields on `session` so they don't leak across connections. * Parameters are inlined at Bind time via `substituteParams` — the resolved SQL is a normal Simple-Query-shaped string the engine sees through the existing `five_SQL(cSQL, …, oSession)` pipeline. Avoids teaching FiveSql2 a second param-shape; the trade-off is that binary timestamps/numerics round-trip through text (Phase 4.1 will plumb `?`-params through aParams for the binary fast path). * `paramToLiteral` decodes the binary-format encodings pgx uses by default for INT4/INT8/BOOL (big-endian fixed-width). Other binary OIDs fall back to a hex-escaped quoted literal which errors loudly rather than silently misparsing. * `countPgPlaceholders` scans the SQL outside string literals for the highest `$N` so the server can answer Describe-statement with a correctly-sized ParameterDescription even when the client didn't pre-declare param OIDs. Without this, pgx errored with "expected 0 arguments, got 2" on the very first prepared query. * RowDescription emission: Describe-statement still returns NoData (we can't infer row shape without execution). When Execute fires on a portal the client never Described, we emit RowDescription inline from the cached result before DataRow streams. pgx and psql both tolerate this ordering. * Execute → CommandComplete tag derives from the SQL verb via the existing `commandTagFor` helper. Row counts in the tag remain "VERB 0" for v1.0; threading real counters through the engine is Phase 5. Wire dispatch in `session.go:queryLoop` now handles Parse, Bind, Describe, Execute, Close, Sync, Flush — the full v3 message set. Verification ------------ End-to-end pgx (default mode, no SimpleProtocol flag) successfully runs: SELECT $1 AS n, $2 AS s with 42 + "hi" → [42 hi] Same statement re-executed with different bound values → reuses the cached prepared statement SELECT $1 AS b, $2 AS s with true + "binary-bool" → [t binary-bool] `tests/pgserver/run.sh` expanded from 1 → 3 integration assertions: PASS Simple Query: SELECT 1, 'hello' PASS Multi-statement Simple Query PASS Transaction control: BEGIN/COMMIT round-trip (Extended Protocol can't be driven from psql's -c CLI directly because psql's PREPARE/EXECUTE is a separate SQL-level feature that FiveSql2 doesn't parse; the pgx-driven path verifies it manually, and a self-contained Go integration that drives pgx from inside a process bootstrap is Phase 7 work.)
