I think the fix here is to avoid the use of an AsyncIterable in fetch if the full body was specified. We can save quite a bit of overhead.

This is indeed tricky. On one hand, state altering verbs should not be automatically retried, on the other hand, it's a pretty common case.

It might be better to just scope this to the safe methods only GET
, HEAD
, and OPTIONS
instead of the idempotent ones.
Tho the issue seems to root the AsyncIterable
that is made out of fetch
.
As the AsyncIterable
has been already consumed at its first request, when the RetryHandler
attempts a new request, the content-length
mismatch surfaces as undici
fails to iterate over the body because it was already consumed.
Not sure what will be the course of action here, I'd say that maybe the handler can make a best attempt to detect specific bodies (Stream, AsyncIterable) and clone them and attempt to free them after successful request. Just will add the overhead of duplicated bodies
from undici.
FWIW I tested directly with Streams
and are handled properly by the RetryHandler
, but facing similar issue to as per fetch with AsyncIterator
(once consumed it does not loop). So this is definitely something that the handler might need to be aware of
from undici.
Streams should not be possible to handle correctly unless they were 0 length.
