Streamlines the vendored @opentelemetry/instrumentation-mysql (#20738), mirroring the already-streamlined mysql2 sibling.

Changes

  • Step 4 (Sentry APIs): span creation moves from the OTel tracer to startInactiveSpan, with the auto.db.otel.mysql origin set directly (new — matches mysql2; the existing tests don't assert origin).
  • Step 2 (remove unused):
    • Connection-pool metrics (db.client.connections.usage counter, pool event listeners, _patchPoolEnd/_patchAdd/_setPoolCallbacks, getPoolNameOld) — Sentry doesn't consume OTel metrics.
    • Semconv-stability dual-emission — collapsed to the default OLD attribute set (db.system/db.name/db.user/db.statement, net.peer.name/net.peer.port), which is what's emitted today.
    • The unused enhancedDatabaseReporting option (the public mysqlIntegration() can't set it) + getDbValues/AttributeNames; MySQLInstrumentationConfig collapses to InstrumentationConfig (so types.ts/AttributeNames.ts are deleted).
  • Step 3 (lint): removed /* eslint-disable */ from all vendored files; they pass the type-aware linter via the shared vendored override.

The OTel context plumbing (trace.setSpan/context.with/context.bind + the pool getConnection context propagation) is intentionally kept to minimize behavior change.

Verification

  • Build + type-aware lint clean.
  • No change to emitted spans. The existing mysql integration tests (step 1, already present) cover the query/callback/stream paths against a real MySQL. Since Docker isn't available in my environment I couldn't run them locally, but a fake-connection smoke test confirms the span output is unchanged:
    op: 'db', description 'SELECT 1 + 1 AS solution' (from db.statement), origin: 'auto.db.otel.mysql', db.system/net.peer.name/net.peer.port/db.user as asserted by the tests.

Closes #20738

Streamlines the vendored `@opentelemetry/instrumentation-mysql`, mirroring the
already-streamlined `mysql2` sibling:

* Migrate span creation from the OpenTelemetry tracer to Sentry's
  `startInactiveSpan`, and set the `auto.db.otel.mysql` span origin directly.
* Remove the connection-pool metrics (`db.client.connections.usage` counter,
  pool event listeners, `_patchPoolEnd`/`_patchAdd`/`_setPoolCallbacks`,
  `getPoolNameOld`) - Sentry does not consume OTel metrics.
* Remove the OTel semconv-stability dual-emission and keep the default (OLD)
  attribute set (`db.system`/`db.name`/`db.user`/`db.statement`,
  `net.peer.name`/`net.peer.port`), which is what the SDK emits today.
* Remove the unused `enhancedDatabaseReporting` option (the public
  `mysqlIntegration()` cannot set it) and its `getDbValues`/`AttributeNames`
  helpers; `MySQLInstrumentationConfig` collapses to `InstrumentationConfig`.
* Remove the `/* eslint-disable */` from the vendored files and make them pass
  the (type-aware) linter via the shared vendored override.

The OTel context plumbing (`trace.setSpan`/`context.with`/`context.bind` and the
pool `getConnection` context propagation) is kept as-is to minimize behavior
change. No change to emitted spans - the existing mysql integration tests cover
the query/callback/stream paths, and a fake-connection smoke test confirms the
span op/description/attributes/origin are unchanged.

Closes #20738

…config

Per review: don't loosen the shared `.oxlintrc` vendored override for the mysql
files; instead resolve the lint findings in the files themselves.

* `mysql-types.ts`: replace the inlined `any`s with `unknown` (index signatures,
  loose `values`/`results`, event-listener args).
* `utils.ts`: type `getConfig`'s parameter instead of `any`.
* `instrumentation.ts`: keep targeted `oxlint-disable-next-line` comments only
  where the shimmer-style wrapping genuinely needs `any`/`this`-aliasing, and
  type the remaining sites (`this: unknown`, `unknown` callback results, the
  streamed-error cast).

Lint is clean (0/0) without the base-config change. Build passes and a
fake-connection smoke test confirms the span output is unchanged.

…origin)

The existing mysql scenarios only covered a single `createConnection` with the
callback and streamed-success paths. Add coverage for the paths the streamlining
touched:

* Assert the `auto.db.otel.mysql` span origin (previously unverified).
* `createPool` + `pool.query` (covers `_patchCreatePool` / `_patchQuery(pool)`).
* A failing streamed query, asserting the span is marked `internal_error` via the
  stream `error` event handler.

… context

Adds a scenario that starts a span from inside a streamed query's `end` listener
and asserts it is parented to the transaction (the context active when the query
was issued), not to the query span - covering the `context.bind(parentContext,
streamableQuery)` behavior in the instrumentation.

Stream queries drop parent context

Medium Severity

For callback-less query calls, the prior instrumentation captured the active context at query start and used OpenTelemetry context.bind on the returned Query so asynchronous error/end listeners (and user code attached via query.on) ran under that parent context, not under the DB span. That bind was removed and only a synchronous withActiveSpan wraps originalQuery, while the captured scope is unused on the stream path. Stream listeners can then run without the transaction scope that was active when the query was issued, so spans started inside those listeners may parent to the wrong span or lose the intended trace hierarchy.
