refactor: move spamoor benchmark into testify suite#3107
Conversation
…mark - Create test/e2e/benchmark/ subpackage with SpamoorSuite (testify/suite) - Move spamoor smoke test into suite as TestSpamoorSmoke - Split helpers into focused files: traces.go, output.go, metrics.go - Introduce resultWriter for defer-based benchmark JSON output - Export shared symbols from evm_test_common.go for cross-package use - Restructure CI to fan-out benchmark jobs and fan-in publishing - Run benchmarks on PRs only when benchmark-related files change
Resolve conflicts keeping the benchmark suite refactoring: - benchmark.yml: keep path filters and suite-style test command - evm_spamoor_smoke_test.go: keep deleted (moved to benchmark pkg) - evm_test_common.go: keep exported types, drop writeTraceBenchmarkJSON (now in benchmark/output.go)

Good refactor overall — isolating the Spamoor benchmark into its own testify suite with a clean I found a few issues ranging from functional bugs to style nitpicks. Bugs / Functional Issues1. OTLP endpoint configuration is incorrect — The OpenTelemetry spec requires // current (broken)
"OTEL_EXPORTER_OTLP_ENDPOINT="+jg.Internal.IngestHTTPEndpoint()+"/v1/traces",
"OTEL_EXPORTER_OTLP_PROTOCOL=http",
"OTEL_EXPORTER_OTLP_TRACES_PROTOCOL=http",
// correct
"OTEL_EXPORTER_OTLP_ENDPOINT="+jg.Internal.IngestHTTPEndpoint(), // base URL, no suffix
"OTEL_EXPORTER_OTLP_PROTOCOL=http/protobuf",
"OTEL_EXPORTER_OTLP_TRACES_PROTOCOL=http/protobuf",
// OTEL_EXPORTER_OTLP_TRACES_ENDPOINT is fine as-is (per-signal = full URL)2. Hardcoded This references an ephemeral PR image tag that will become invalid once the image is cleaned up. It should be configurable via an env var with a sensible default so CI can override it without a code change. rethTag := os.Getenv("BENCH_RETH_TAG")
if rethTag == "" {
rethTag = "pr-140"
}
e := s.setupEnv(config{
rethTag: rethTag,
serviceName: "ev-node-smoke",
})Design / Robustness3.
data, err := json.MarshalIndent(w.entries, "", " ")
if err != nil {
w.t.Logf("WARNING: failed to marshal benchmark JSON: %v", err)
return
}
if err := os.WriteFile(outputPath, data, 0644); err != nil {
w.t.Logf("WARNING: failed to write benchmark JSON to %s: %v", outputPath, err)
return
}4. Fixed 60-second sleep for trace accumulation — This is the canonical fragile-test antipattern. On slow CI runners it may be too short; on fast machines it wastes time. The 5.
Code Quality Nitpicks6. Loop variable for _, t := range traces { // 't' reads as testing.TB to any Go developerRename to 7. Stale doc comment — The comment still says // SetupCommonEVMEnv creates and initializes ev-reth instances...8. The polling loop uses CI9. Missing path trigger for Block Executor benchmarks — The Note: I cannot modify workflow files directly (GitHub App permission restriction), but this is a straightforward one-liner addition to the Performance RegressionThe benchmark-action comment shows 3 Spamoor metrics regressed >1.5x vs the previous run. These are likely noise from the infrastructure refactor rather than a code regression, but worth checking:
These could be caused by the new suite initialization overhead or Docker orchestration differences in the refactored setup. Summary: The structural refactor is clean and the direction is right. The two hard-blockers before merge are the OTLP endpoint misconfiguration (items 1) which will produce silently incorrect tracing data, and the hardcoded PR image tag (item 2) which will cause test failures once that image is cleaned up. |

go test sets the working directory to the package under test, so the env var should be relative to test/e2e/benchmark/, not test/e2e/.

20-23:⚠️ Potential issue | 🟠 MajorHardcoded
rethTag: "pr-140"will become stale and cause opaque failures.This tag refers to a specific container image built for a PR. Once that image is cleaned up or the tag is overwritten, the test will silently fail to start or pull the container with a confusing error. Expose this via an environment variable or CLI flag so it can be updated without a code change.

🌐 Web query:
OpenTelemetry OTEL_EXPORTER_OTLP_ENDPOINT specification base URL path suffix
💡 Result:
For OTLP/HTTP, OTEL_EXPORTER_OTLP_ENDPOINT is specified as a base URL. Exporters must append a signal-specific relative path to it:
- Traces:
v1/traces - Metrics:
v1/metrics - Logs:
v1/logs
So if you set:
OTEL_EXPORTER_OTLP_ENDPOINT=http://collector:4318
the actual requests go to:
http://collector:4318/v1/traces,.../v1/metrics,.../v1/logs(respectively). The base URL may itself include a path prefix (e.g./mycollector/), in which case thev1/*suffix is appended under that prefix. [1]
If you instead set a per-signal endpoint (e.g. OTEL_EXPORTER_OTLP_TRACES_ENDPOINT), that URL is used as-is (no automatic /v1/traces appending); if it has no path component, / is used. [1]
Separately, the OTLP protocol spec defines the default OTLP/HTTP paths as /v1/traces, /v1/metrics, /v1/logs (server-side defaults), but clients may be configured to use non-default paths. [2]
For OTLP/gRPC, OTEL_EXPORTER_OTLP_ENDPOINT is a target for the gRPC client (typically host/port; path suffixes like /v1/traces are not part of the gRPC endpoint concept). [1]

Reth OTLP exporter HTTP protocol http/protobuf http/json specification
💡 Result:
OTLP exporter over HTTP: http/protobuf vs http/json (spec)
Transport & endpoints (OTLP/HTTP):
- Uses HTTP POST over HTTP/1.1 or HTTP/2. (opentelemetry.io)
- Default URL paths:
- Traces:
POST /v1/traceswithExportTraceServiceRequest - Metrics:
POST /v1/metricswithExportMetricsServiceRequest - Logs:
POST /v1/logswithExportLogsServiceRequest(opentelemetry.io)
- Traces:
- When SDKs are configured with a base endpoint (
OTEL_EXPORTER_OTLP_ENDPOINT), they construct per-signal URLs by appendingv1/traces,v1/metrics,v1/logs(unless a per-signal endpoint is set). (opentelemetry.io)
Encoding choices (same protobuf schema, different wire format):
http/protobuf: protobuf messages serialized in binary proto3. (opentelemetry.io)Content-Type: application/x-protobuf(request + response). (opentelemetry.io)
http/json: protobuf messages serialized using protobuf JSON mapping, with OTLP-specific rules. (opentelemetry.io)Content-Type: application/json(request + response). (opentelemetry.io)
OTLP JSON-specific mapping rules (important for http/json):
traceId/spanIdare hex strings (not base64). (opentelemetry.io)- Enums MUST be integers (enum names not allowed). (opentelemetry.io)
- Unknown JSON fields must be ignored by receivers. (opentelemetry.io)
- JSON field names are lowerCamelCase. (opentelemetry.io)
- 64-bit integers in JSON are encoded as decimal strings (numbers or strings accepted when decoding). (opentelemetry.io)
Compression:
- Client may gzip the request body; if so it MUST send
Content-Encoding: gzip. (opentelemetry.io) - Client may send
Accept-Encoding: gzip; server may gzip responses. (opentelemetry.io)
Responses:
- Success is HTTP 200 OK with an
Export<signal>ServiceResponse(e.g.,ExportTraceServiceResponse). (opentelemetry.io) - Server must respond using the same Content-Type it received. (opentelemetry.io)
How exporters select protocol:
OTEL_EXPORTER_OTLP_PROTOCOL(and per-signal variants) supports:grpc,http/protobuf,http/json; default is typicallyhttp/protobuf. (opentelemetry.io)

Remove the /v1/traces suffix from OTEL_EXPORTER_OTLP_ENDPOINT and change protocol values to http/protobuf.
The OpenTelemetry specification requires that OTEL_EXPORTER_OTLP_ENDPOINT be a base URL, with the SDK automatically appending signal-specific paths (/v1/traces, /v1/metrics, /v1/logs). Setting it to …/v1/traces will cause requests to be sent to …/v1/traces/v1/traces. The per-signal endpoint OTEL_EXPORTER_OTLP_TRACES_ENDPOINT is correct as-is since it expects the full URL without automatic appending.
Additionally, OTEL_EXPORTER_OTLP_PROTOCOL and OTEL_EXPORTER_OTLP_TRACES_PROTOCOL must use spec-defined values: grpc, http/protobuf, or http/json. The value "http" is not valid.
Proposed fix

In `@test/e2e/benchmark/suite_test.go` around lines 73 - 78, The OTLP env setup in
the b.WithTag(...).WithEnv call is wrong: change the value for
"OTEL_EXPORTER_OTLP_ENDPOINT" to use the base ingest URL (remove the
"/v1/traces" suffix) so the SDK can append per-signal paths, keep
"OTEL_EXPORTER_OTLP_TRACES_ENDPOINT" as-is (full URL), and update
"OTEL_EXPORTER_OTLP_PROTOCOL" and "OTEL_EXPORTER_OTLP_TRACES_PROTOCOL" from
"http" to the spec-correct "http/protobuf" (or another valid spec value like
"grpc" or "http/json" if intended).
go test treats all arguments after an unknown flag (--evm-binary) as test binary args, so ./benchmark/ was never recognized as a package pattern.
go test sets the cwd to the package directory (test/e2e/benchmark/), so the binary path needs an extra parent traversal.

This comment was automatically generated by workflow using github-action-benchmark.
The benchmark package doesn't define the --binary flag that test-e2e passes. It has its own CI workflow so it doesn't need to run here.
