fix(adapters): thread abort signal into image normalization call sites - #5226
Conversation
Completes review findings left open when lidge-jun#5208 merged: normalizeAnthropicImages now receives the request abort signal at the anthropic adapter and claude-messages passthrough call sites (abortSignal moves onto NormalizeOptions so both entry points accept it), and the decode gate re-checks aborted after admission so a request cancelled while queued never starts a native decode. Adds regression coverage for the post-admission abort and for rejecting an image whose dimensions header cannot be sniffed.

📝 WalkthroughWalkthroughThe change propagates request abort signals into Anthropic image normalization, adds a pre-decode abort check, and tests cancellation timing. It also tests rejection of oversized BMP metadata when initial dimension sniffing returns no result. ChangesImage normalization safeguards

Check cancellation before selecting another target.
At Line 147, abortSignal is checked only after a target reaches process(). A pre-aborted request that contains only targets skipped by the worker, such as URL targets, process-limited targets, length-capped targets, or targets rejected by dimension sniffing, resolves normally. This conflicts with the NormalizeOptions.abortSignal cancellation contract.
Check abortSignal at the start of each worker iteration before incrementing nextIndex. Reuse the same abort error construction.
Proposed fix
const worker = async (): Promise<void> => {
// A fatal error stops workers from pulling NEW indices; in-flight items settle.
while (!failed) {
+ if (abortSignal?.aborted) {
+ throw abortSignal.reason ?? new DOMException("Aborted", "AbortError");
+ }

리뷰 · 우선순위 46 / 80손님이 연결을 끊어도, 그림 크기를 맞추는 일은 두 입구에서 계속 돌았습니다. Anthropic이 요청을 만드는 곳과, Claude 메시지를 그대로 넘기는 곳입니다. #5208은 취소 신호를 OpenAI 쪽까지만 넣었습니다. 이 PR은 그 두 입구에도 같은 신호를 넣습니다. 신호 칸은 그림 정규화 공통 옵션으로 옮겼습니다. 두 입구가 같은 함수에 신호를 넘길 수 있게 하려는 자리입니다. Anthropic 어댑터는 이미 들고 있던 디코드 자리를 받은 직후에도 한 번 더 봅니다. 줄에서 기다리는 동안 끊기면, 자리가 넘어온 뒤에 풀기가 시작되지 않습니다. 이미 디코더 안에 들어간 한 장은 여전히 중간에서 못 끊습니다. Bun 디코드가 신호를 받지 않기 때문입니다. 테스트는 세 가지를 봅니다. 이미 끊긴 요청은 디코드를 시작하지 않습니다. 자리를 받은 뒤, 풀기 직전에 끊기면 인코드 함수가 안 불립니다. 헤더에서 크기를 못 읽는 BMP가 5000×4000이라고 적어도, 코덱이 알려 준 크기로 거절합니다. 그 그림은 한 번 시도한 뒤 빠지고, OpenAI 쪽은 원래 주소를 그대로 둡니다. 베이스는 라인 - src/adapters/anthropic-image-normalize.ts:174 - 워커는 다음 그림을 집기 전에 취소를 안 봅니다. 취소 검사는 메인테이너의 판단이 필요한 지점 그 어긋남을 머지 전에 막을지입니다. 디코드가 시작되는 길은 이미 막혀 있습니다. 빠지는 그림만 있는 요청이 에러 없이 끝나는 것을 계약 위반으로 볼지, 디코드만 멈추면 충분한지가 판단입니다. 너의 추천 #5208에서 남긴 세 가지는 이 PR이 채웁니다. 신호는 두 입구에 들어가고, 자리 직후 검사는 있습니다. 헤더를 못 읽는 큰 그림 테스트도 있습니다. 워커 맨 앞에서 취소를 보는 것은 다음으로 미뤄도 됩니다. 지금 상태로 머지해도 됩니다. 닫을 중복 PR은 없습니다. 이 댓글은 grok-bot이 작성했습니다 |
