[-]Streams: reject pending reads when releasing reader[/-][+]Web Streams: reject pending reads when releasing reader[/+]on Jan 13, 2022 Hello. Every time I run
reader.releaseLock(), an error is generated at any time, even on a newly created stream
TypeError [ERR_INVALID_STATE]: Invalid state: Reader released@essential-existence I suggest you open a separate issue for that. This issue is about implementing a change to
releaseLock().That said, I am a bit curious. That error appears as the rejection reason for
reader.closed, but that promise is always marked as handled so it shouldn't cause an unhandled rejection. Unless your code is doing something else withreader.closed, perhaps? I recommend you add some example code when opening a new issue. 😉Great to see this change landed in the spec! Definitely will be nice to get this behavior implemented.

Thank you auto-close bot bit I think this one needs to stay open for a bit still (unless it has already been resolved?)

Previously, calling
ReadableStreamDefaultReader.releaseLock()orReadableStreamBYOBReader.releaseLock()while there are pendingread()requests would throw aTypeError.The specification has been changed to allow this case, and to reject such pending
read()requests instead.Standard change: whatwg/streams#1168
Tests: web-platform-tests/wpt#32072
