Summary

  • replace removed TypeScript/k6 integration invocations with registered Go workloads and typed flags
  • make PostgreSQL, MySQL, CSV, and OTEL coverage mandatory through one tagged integration target and CI job
  • validate current load, transaction, procedure, query, merged/sharded CSV, manifest, timeout, and exported-metric behavior
  • keep Picodata/YDB and heavy TPC-H SF=1 validation available through explicit optional targets
  • finalize the primary driver during run teardown so CSV output and manifests are complete before return

Stack

Validation

  • make integration with fresh PostgreSQL 17 and MySQL 8.0 services
  • make tests TEST_FLAGS=-short
  • go test -race ./pkg/driver/csv -count=20
  • optional integration build-tag compile
  • pinned golangci-lint v2.12.2 under Go 1.26
  • both Docker Compose configurations

Closes #136

Summary by CodeRabbit

  • New Features

    • Added streamlined integration test commands for baseline, optional database, and TPC-H SF=1 suites.
    • Added MySQL 8.0 support to the integration test environment.
    • Added optional TPC-H coverage for Picodata and YDB.
    • Expanded workload, CSV, database, and OpenTelemetry integration coverage.
  • Bug Fixes

    • CSV output, manifests, merged files, and sidecars are now published atomically.
    • Incomplete or cancelled CSV generations no longer replace valid output.
    • Driver teardown now runs reliably and reports failures.

📝 Walkthrough

Walkthrough

The PR adds mandatory PostgreSQL/MySQL integration execution, migrates tests to registered Go workloads, adds optional database suites and TPC-H SF=1 validation, hardens CSV publication, and ensures benchmark driver teardown runs with cancellation-safe error reporting. The OpenTelemetry test file retains unresolved references after helper removal.

Changes

Integration and lifecycle changes

Layer / File(s) Summary
Driver teardown lifecycle
pkg/bench/runtime.go, pkg/bench/runtime_test.go, cmd/stroppy/commands/help/topic_drivers.go, AGENTS.md
Driver teardown now runs with a detached 30-second context. Teardown errors join existing run errors. Tests verify ordering, context properties, and error propagation.
CSV generation and atomic publication
pkg/driver/csv/*
CSV inserts now track failed generations, validate shard state, honor cancellation, and publish merged files, sidecars, and manifests atomically.
CSV lifecycle validation
pkg/driver/csv/insert_test.go, test/integration/csv_test.go, testdata/csv/tpcb_sf1/*
Tests cover repeated and replacement generations, failures, retries, cancellation, shard validation, manifests, deterministic output, and updated golden hashes.
Baseline and optional integration harnesses
.github/workflows/integration.yml, Makefile, test/compose.tmpfs.yml, test/integration/{multidb.go,tmpfs.go}, AGENTS.md
The harness adds MySQL 8.0, tagged integration targets, URL overrides, optional Picodata/YDB targets, and mandatory execution without skip switches.
Go workload integration coverage
test/integration/{tpcb*,tpcc*,tpch*}
TPC-B, TPC-C, and TPC-H tests now use shared registered-workload execution. MySQL coverage and optional Picodata/YDB TPC-H tests are added.
OpenTelemetry metric helpers
test/integration/otel_metrics_helpers_test.go, test/integration/otel_metrics_test.go
Prometheus parsing and assertion helpers move to a separate file, but the metrics test still references removed declarations and functions.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟡 Moderate · up to ed3ea

The integration suite can falsely pass or become flaky because several assertions accept incomplete or malformed results, including load markers, generated row counts, metric labels, and trailing metric fields. Merge readiness therefore requires fixing these bounded validation issues or obtaining explicit owner acceptance.

Explanation

The pull request addresses the linked issue objectives for Go-native workloads, documented integration targets, mandatory PostgreSQL CI, MySQL coverage, CSV validation, and removal of skip paths. However, test/integration/otel_metrics_test.go still references removed types and functions, which causes unresolved identifiers and prevents the integration package from compiling.

Full details: Out of Scope Changes check

Explanation

The changes support the stated integration objectives. The optional Picodata and YDB tests are isolated in the optional suite, and the CSV teardown changes support complete output publication. No unrelated code changes are evident.

Addressed the remaining CodeRabbit review-body items in 79aecdb:

  • limited the integration job token to contents: read;
  • removed the internal integration-coverage changelog entry while retaining the user-facing CSV publication fix;
  • moved the pure Prometheus parser and Docker-output tests, with their helpers, into an untagged test file so default go test ./... executes them.

Validated with make build, make tests, GOTOOLCHAIN=go1.26.5 make linter, and the full PostgreSQL/MySQL/CSV/OTEL make integration suite.

Reject malformed trailing sample fields.

parsePrometheusSampleLine parses only fields[0] and accepts all remaining fields. Thus, malformed samples such as stroppy_metric 7 invalid are accepted. waitForMetrics can then stop retrying when the first value matches.

Accept one value field or one value plus an optional int64 timestamp. Validate the timestamp with strconv.ParseInt. Add regression cases for invalid timestamps and extra fields.

Addressed CodeRabbit’s outside-diff parser comment in 8384251.

parsePrometheusSampleLine now accepts exactly a value or a value plus an optional signed int64 timestamp. Invalid timestamps and extra trailing fields return parse errors. Regression cases cover value-only samples, valid timestamps, invalid timestamps, and extra fields.

Validated with go test -race ./test/integration, tagged integration compilation, make tests, GOTOOLCHAIN=go1.26.5 make linter, and the full PostgreSQL/MySQL/CSV/OTEL make integration suite.
