feat(core)!: Remove enableTruncation flag and all AI integrations truncation logic - #23045
Merged
Conversation
Remove genai text truncation: - Removes the `enableTruncation` integration option and all gen_ai text-truncation logic (`messageTruncation.ts`); byte-limit cropping and "keep only the last message" are gone now that gen_ai spans always use the v2 span path. - Keeps inline media stripping and makes it unconditional, so this is now being applied to both transaction and span streaming paths. - All input messages are now recorded in full (media stripped), stripping is consolidated into `mediaStripping.ts`. - Covers both `@sentry/core` and `@sentry/server-utils`. - Removes truncation specific tests. Adds a new span streaming scenario because the span streaming path was so far only tested together with truncation. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Media stripping was the last piece of gen_ai input processing left after truncation removal. Since gen_ai spans always use the v2 span path (not subject to transaction payload-size limits), full input messages — including inline media (base64 images, audio, files) — are now recorded verbatim. - Delete `mediaStripping.ts` and the `getGenAiMessagesJsonString` helper; call sites now use `stringify` from `@sentry/core` directly. - Collapse langchain's `normalizeContent` into `stringify` now that it no longer strips media. - Remove media-stripping unit tests and the anthropic/openai media scenarios; the node integration suites already assert the full output format.

enableTruncation flag and gen_ai text truncationenableTruncation flag and all AI integrations truncation logic
The per-suite span-streaming tests existed only to prove input messages were recorded in full (not truncated) — firing 50k-char payloads. With no message-modifying logic left in the SDK, that assertion is redundant. Reuse each suite's basic scenario against `instrument-streaming.mjs` and assert the same core span attributes as the static-lifecycle base tests, so the `traceLifecycle: 'stream'` path stays covered without the truncation framing or giant payloads. Delete the now-unused `scenario-span-streaming.mjs` files. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
…reaming `instrument-streaming.mjs` configures `traceLifecycle: 'stream'` (span streaming), which is easily confused with the `scenario-stream*` files that exercise streaming *responses* — a different concept. Rename to `instrument-span-streaming.mjs` to disambiguate. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

…ale comments With no message-truncation logic left in the SDK, tests that assert "we keep the full message" or use giant payloads to prove non-truncation exercise behavior that no longer exists. - Remove the duplicate "keeps all messages including inline media" test (same code path as the plain serialization test). - Reword the 200k-char "without truncation" anthropic test to a basic input messages check, drop the "non-array input" case (pure `stringify`, covered in core), and make the empty-array test self-contained. - Fix stale comments/JSDoc that still referenced truncation.

…ests
The span-streaming tests reuse the basic scenarios, which also emit event
envelopes (error-model exceptions, captureMessage). The tests only assert on a
span envelope and don't ignore events, so under the ordered envelope matcher an
event arriving before the span would fail the test — it passed only because the
streamed span happened to match first. Add `.ignore('event')` so the outcome no
longer depends on envelope timing.

…ests `addRequestAttributes` no longer takes the `enableTruncation` parameter, but six call sites in the workers-ai utils test still passed a trailing `false`. JS ignores the extra arg so the tests passed, but they were stale — remove it. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
