Summary

  • expose root stroppy package for one-workload standalone applications through New, Main, Application.Execute, and Application.Run
  • add explicit workload factories and catalogs so custom applications avoid process-global registration
  • reuse installed Stroppy run, probe, help, version, driver, config, metrics, report, and cancellation behavior
  • bundle repository-defined standard drivers without user-maintained blank imports
  • save constructed run reports under ~/.stroppy/reports/, warning rather than failing on automatic history errors
  • verify a separate module can build and run default workload, help, probe, version, JSON report, and report history

Validation

  • make tests TEST_FLAGS=-short
  • GOTOOLCHAIN=go1.26.0 go run github.com/golangci/golangci-lint/v2/cmd/golangci-lint@v2.12.2 --config .golangci.yml run
  • go test ./test/modulecompat -count=1
  • make build

Closes #175

Stacked on #181; rebase onto main after #181 merges.

Summary by CodeRabbit

  • New Features
    • Custom Go workloads can run as standalone applications with Stroppy’s CLI, drivers, probes, metrics, and reporting.
    • Workloads can be run through the CLI or programmatically.
    • Workload reports are automatically saved to ~/.stroppy/reports/. Use --no-report to disable report creation and history.
  • Bug Fixes
    • Automatic report-history save failures warn without failing the workload run.
    • Report and metrics version information now reflects the resolved build version.
  • Documentation
    • Added a standalone workloads guide and updated the Quick Start and report documentation.

📝 Walkthrough

Walkthrough

This change adds support for standalone Go workload applications. It introduces workload catalogs and factory-based execution, reusable CLI construction, programmatic runtime methods, and automatic report history.

Changes

Standalone Workloads

Layer / File(s) Summary
Workload catalogs and factory execution
pkg/bench/catalog.go, pkg/bench/runtime.go, pkg/bench/catalog_test.go
Factories can be stored in isolated catalogs or accessed through the registered catalog. Description and run APIs support factories and catalogs, and catalog execution checks workload names.
Report history and runtime metadata
pkg/report/*, pkg/bench/metrics_provider.go, pkg/bench/root.go, internal/version/*, cmd/stroppy/commands/run/run.go, cmd/stroppy/commands/baseline/baseline.go, pkg/driver/csv/manifest.go, docs/run-reports.md
Constructed reports can be saved under ~/.stroppy/reports/. Metrics summaries accept a configured writer, and report metadata uses the resolved version.
Reusable CLI construction and workload dispatch
internal/cli/root.go, cmd/stroppy/commands/*
The reusable CLI builds commands from supplied catalogs. Run, probe, help, and baseline commands now have command constructors, and workload dispatch uses the supplied catalog.
Standalone application API and integration
stroppy.go, stroppy_test.go, docs/standalone-workloads.md, README.md, CHANGELOG.md, test/modulecompat/*
The stroppy package adds application construction, CLI execution, direct workload execution, and Main. Documentation and external-module tests cover standalone workloads.

Review comments at @internal/cli/root.go:
- Line 111: Remove the hard-coded ydb_service_account_key_file entry from the
JSON output path in the version command in root.go; keep the existing component
versions and JSON encoding behavior unchanged.

Review comments at @pkg/bench/runtime.go:
- Around line 241-325: Pass the requested catalog key from RunCatalog and
RunCatalogWithReport into run as the expected workload name, and reject a fresh
name mismatch before defineWorkload or execution. Keep non-catalog factory runs
unvalidated by passing no expected name.

Review comments at @stroppy.go:
- Around line 124-131: In Application.Run, avoid modifying the caller-owned
request.Metrics when applying the ServiceVersion default. Create a local
MetricsConfig copy when request.Metrics is non-nil, use a fresh config
otherwise, and apply defaults to that local config.
