This is enforced via `onlyIfParent`, which still creates a non-recording span so trace propagation headers are injected. This rule already lives in `SentrySampler`, but that only runs when an OpenTelemetry SDK tracer provider is set up. Enforcing it in the instrumentation makes it hold for the `SentryTracerProvider` and for SDKs that don't use an OpenTelemetry tracer provider at all. The sampler rule is kept for OpenTelemetry SDK / custom OpenTelemetry setups. --- .../scenario-fetch.mjs | 1 + .../no-parent-span-client-report/test.ts | 23 ++++++++++++++++++- .../node-fetch/undici-instrumentation.ts | 10 ++++++++ 3 files changed, 33 insertions(+), 1 deletion(-) create mode 100644 dev-packages/node-integration-tests/suites/tracing/no-parent-span-client-report/scenario-fetch.mjs diff --git a/dev-packages/node-integration-tests/suites/tracing/no-parent-span-client-report/scenario-fetch.mjs b/dev-packages/node-integration-tests/suites/tracing/no-parent-span-client-report/scenario-fetch.mjs new file mode 100644 index 000000000000..a122330366e4 --- /dev/null +++ b/dev-packages/node-integration-tests/suites/tracing/no-parent-span-client-report/scenario-fetch.mjs @@ -0,0 +1 @@ +fetch('http://localhost:9999/external').catch(() => {}); diff --git a/dev-packages/node-integration-tests/suites/tracing/no-parent-span-client-report/test.ts b/dev-packages/node-integration-tests/suites/tracing/no-parent-span-client-report/test.ts index 699dec65ddcf..4ad1b3150f2c 100644 --- a/dev-packages/node-integration-tests/suites/tracing/no-parent-span-client-report/test.ts +++ b/dev-packages/node-integration-tests/suites/tracing/no-parent-span-client-report/test.ts @@ -7,7 +7,28 @@ describe('no_parent_span client report', () => { }); createEsmAndCjsTests(__dirname, 'scenario.mjs', 'instrument.mjs', (createRunner, test) => { - test('records no_parent_span outcome for http.client span without a local parent', async () => { + test('records no_parent_span outcome for an outgoing http request without a local parent', async () => { + const runner = createRunner() + .unignore('client_report') + .expect({ + client_report: report => { + expect(report.discarded_events).toEqual([ + { + category: 'span', + quantity: 1, + reason: 'no_parent_span', + }, + ]); + }, + }) + .start(); + + await runner.completed(); + }); + }); + + createEsmAndCjsTests(__dirname, 'scenario-fetch.mjs', 'instrument.mjs', (createRunner, test) => { + test('records no_parent_span outcome for an outgoing fetch request without a local parent', async () => { const runner = createRunner() .unignore('client_report') .expect({ diff --git a/packages/node-core/src/integrations/node-fetch/undici-instrumentation.ts b/packages/node-core/src/integrations/node-fetch/undici-instrumentation.ts index d35a89756ba3..33ff9ced837b 100644 --- a/packages/node-core/src/integrations/node-fetch/undici-instrumentation.ts +++ b/packages/node-core/src/integrations/node-fetch/undici-instrumentation.ts @@ -22,6 +22,8 @@ import { URL } from 'url'; import type { Span, SpanAttributes } from '@sentry/core'; import { debug, + getClient, + hasSpanStreamingEnabled, isTracingSuppressed, LRUMap, SEMANTIC_ATTRIBUTE_SENTRY_CUSTOM_SPAN_NAME, @@ -253,10 +255,18 @@ function onRequestCreated(config: NodeFetchOptions, { request }: RequestMessage) attributes[USER_AGENT_ORIGINAL] = userAgent; } + // Outside of span streaming, only record an `http.client` span when it has a parent.

The SentryTracerProvider's tracer has no `_idGenerator`, so the shim bailed and dropped every engine span, leaving only the `prisma:client:*` spans. Replace the hack with a span registry: client spans register by their span id on `spanStart`, and each v5 engine span is created under the parent it references by id via `startInactiveSpan`. Engine spans whose parent hasn't been seen yet wait in a pending buffer until a later batch registers it, reproducing the flat `parent_span_id` regrouping the OTel SDK exporter used to do.
