Summary

Fixes #2355.

A client derived with $setOptions (like every derived client) reuses the base client's ZenStackDriver. That driver adds logging by patching each pooled connection the first time it's acquired, only if the base client's log enables it, and always logs with the base client's Log. So $setOptions({ ...db.$options, log }) could not turn logging on, switch to another logger, or turn it off.

const db = new ZenStackClient(schema, { dialect });
const logged = db.$setOptions({ ...db.$options, log: ['query'] });
await logged.user.findMany(); // before: nothing logged

Changes

  • zenstack-driver.ts
    • The pool-level state (underlying driver, init/destroy lifecycle, sqlite connection mutex, transaction bookkeeping) is kept in one shared state object. withLog(log) returns a driver over the same state with its own Log, so derived clients keep sharing one connection pool.
    • When a driver acquires a connection, it records its log for that connection. Kysely drivers hand out a connection to one holder at a time until it's released, so queries on it are logged with the log of the client that acquired it.
    • A connection is patched once, the first time a driver with logging enabled acquires it (previously a connection first acquired without logging was never patched). The patched methods read the connection's current log on each query and skip timing and logging when nothing is enabled.
  • client-impl.ts: a derived client whose log option differs from its base (identity check) uses withLog(new Log(options.log ?? [])) for its executor and its $qbRaw Kysely instance. $use, $setAuth, $transaction and similar keep the same log reference, so they keep the base driver as before.

Known limitation: calling $setOptions with a different log on a client inside an interactive transaction still logs that transaction's queries with the logger that started it, because those queries run on the connection the transaction already holds.

Overlap with #2899: both PRs change the connection provider argument in the derived-client branch of client-impl.ts. Whichever lands second can combine them as baseClient.isTransaction ? (baseClient.transactionConnection ?? baseClient.$qb.getExecutor()) : new DefaultConnectionProvider(driver), with the executor taking driver.

Validation

  • New tests/regression/test/issue-2355.test.ts covers:

    • enabling, switching and disabling logging with $setOptions
    • logging on transactions started from the derived client and on $qbRaw
    • failed queries logged with level error
    • concurrent queries from a base and a derived client going to their own loggers
    • clients derived without changing log keeping the base logger

    Without the change, 7 of the 8 tests fail in 3 of 3 runs; with it, all 8 pass in 3 of 3 runs.

  • tests/e2e ORM suites that create derived clients and use the driver (client-api/transaction, raw-query, slicing, omit, error-handling, plugin-infra/*): 183 passed before and after. packages/orm unit tests: 7 passed before and after.

  • @zenstackhq/orm lint and build (tsc + tsdown), tsc for tests/regression and prettier on the changed files pass.

  • Ran on SQLite only (Node 24, pnpm 10.33.0, in a container). The PostgreSQL and MySQL legs of the CI matrix were not run locally.

This change was written with help from an AI coding assistant (Claude Code).

Summary by CodeRabbit

  • Bug Fixes
    • Query logging now respects logging options configured on derived clients, including when logging is enabled or disabled. Queries, transactions, raw queries, and failed operations are logged by the client that runs them, with concurrent queries kept separate.
    • Derived clients that retain the base client’s logging options continue to share its logging behavior.

Derived clients reused the base client's ZenStackDriver, which patches
pooled connections for logging only if the base client's log enables it
and always logs with the base client's Log, so `$setOptions` couldn't
enable, change or disable logging.

ZenStackDriver now keeps its pool-level state (underlying driver,
lifecycle, sqlite mutex, transaction bookkeeping) in a shared object.
`withLog()` creates a driver over the same state with its own Log. The
acquiring driver's log is recorded per connection, and patched
connections look it up on each query. A derived client whose `log`
differs from its base uses `withLog()` for its executor and `$qbRaw`.

Fixes zenstackhq#2355

Walkthrough

Derived clients now use their own logger when their log option differs from the base client’s. They share driver state and connections. Regression tests cover logging across queries, transactions, errors, and concurrent base and derived client operations.

Changes: Derived-client logging

Layer / File(s) Summary
Shared driver state
packages/orm/src/client/executor/zenstack-driver.ts
ZenStackDriver stores driver, lifecycle, connection, and transaction state in shared state that logger-specific driver instances can reuse.
Connection-level logging
packages/orm/src/client/executor/zenstack-driver.ts
Connection acquisition associates the current driver’s logger with the connection. Query and stream wrappers use that logger to report errors and successful operations with duration data.
Derived-client driver selection
packages/orm/src/client/client-impl.ts
When the log option differs from the base client’s, the derived client uses a logger-specific driver and raw Kysely instance. Otherwise, it reuses the base instances.
Logging regression coverage
tests/regression/test/issue-2355.test.ts
Tests cover log configuration, base and derived client event routing, transactions, errors, raw query builders, and concurrent queries.

Full details: Title check

Explanation

The title names the main change: derived clients created with $setOptions now honor their own log option. The changeset matches this. It changes the driver, the logger routing in ZenStackDriver, and the derived-client creation in client-impl.ts, and it adds regression tests for issue 2355. The title is specific, concise, and in the conventional commit format.

Full details: Linked Issues check

Explanation

Issue #2355 requires $setOptions to enable logging. client-impl.ts detects a changed log option and uses ZenStackDriver.withLog(...) for the derived executor and $qbRaw. The shared driver state preserves the connection pool. The regression test issue-2355.test.ts verifies logging from the derived client, including transaction and raw-query paths.

Full details: Out of Scope Changes check

Explanation

The changes stay within issue #2355. Shared driver state is required to apply a different logger without creating a separate pool. Switching and disabling logging, error logging, transaction coverage, raw-query coverage, and concurrency tests validate related behavior. No unrelated production feature or unrelated test change is shown.

Clear the PostgreSQL connection logger before releasing the connection.

For PostgreSQL, pg-pool can hand a released connection to a queued acquisition before ZenStackDriver.releaseConnection() reaches cleanup. The acquisition hook can then use the previous client's logger, including when the new client disables logging.

Suggested fix
    async releaseConnection(connection: DatabaseConnection): Promise<void> {
+        this.#state.connectionLogs.delete(connection);
        try {
            await this.#state.driver.releaseConnection(connection);
        } finally {
            this.#state.connectionMutex?.releaseLock();
        }
    }
