stream: make all streams error in a pipeline by mcollina · Pull Request #30869 · nodejs/node

mcollina · 2019-12-09T19:52:22Z

This changes makes all stream in a pipeline emit 'error' in
case of an abnormal termination of the pipeline. If the last stream
is currently being async iterated, this change will make the iteration
reject accordingly.

See: #30861
Fixes: #28194

This will require some thoughts on a semverness profile. On one hand, it's a change of behavior. On the other hand, it's a needed fix for a key feature in streams.

Regardless, it's worth an update on docs, that's why it's a draft.

LGTM, I like it

LGTM, Thanks @mcollina

I think it would be better if we can drop the mandatory callback though.

👍 the destroy with no error was originally added to support v old streams where the 1st arg was a function afair.

(There are some CITGM failures that seems unrelated)

mafintosh · 2019-12-09T21:20:14Z

I’d say this is semver patch as the destroy(cb) is ancient. I originally wrote that +5 years ago.

mcollina · 2019-12-10T09:44:47Z

The docs already mention calling .destroy(err).

I'm adding the backport-requested label because it seems like this shouldn't land without #31054
