The cloned writable problem

1

**Principle:** cloning a stream should be a no-op (except that queue size increases by one chunk). # Cloning formulas "Cloning" is an operation which locks the original stream and constructs...

Does pipeTo() wait for writes to complete even when there are no writes?

In #941, we got a PR from someone who wasn't aware of the participation agreement requirement. Looking at CONTRIBUTING.md and README.md, nothing stood out as mentioning the requirement. To avoid...

reader.read() inside strategy.size() doesn't work

If I understand correctly, the following test should pass: ```javascript promise_test(() => { let controller; let readPromise; let reader; const rs = new ReadableStream({ start(c) { controller = c; }...

Tests contain non-zero timers

Short timers make tests flaky. From the [Testharness.js API Documentation](http://testthewebforward.org/docs/testharness-library.html): > Note that timeouts generally need to be a few seconds long in order to produce stable results in all...

Calling sink.abort() after a sink method rejection could lead to double cleanup

3

This was raised by @tyoshino in https://github.com/w3c/web-platform-tests/pull/5421#discussion_r111348353 Consider the following sink: ```javascript new WritableStream({ write(chunk) { return handle.write(chunk) .catch(reason => { cleanup(); return Promise.reject(reason); }); } close() { handle.flush(); cleanup();...

us.abort() is not called if us.write() fails

6

Currently an exception or rejection from `us.write()` will not result in `us.abort()` being called. If the underlying sink wants to free resources, it has to do it before returning the...

Export the "error the stream" concept?

For the Encoding Standard, it would be useful to be able to talk about erroring the stream. However, while the Streams Standard uses the term in the few places, it...

This is arguably a Chromium issue but since the tests will arrive at Chromium via the the w3c web-platform-tests I am filing it here. It will be useful for any...
