1157434 - Cache Add/AddAll should abort in-flight Fetch requests on error

Status: NEW

(Core :: DOM: Core & HTML, defect, P3)

Description

[Ben Kelly [:bkelly, not reviewing]]

After bug 1120501 lands the Cache Add() and AddAll() methods will immediately reject when an error occurs without aborting in-progress Fetch requests.  This is mainly because the current FetchRequest() interface does provide a way to abort.

There is ongoing work to expose a public way to abort Fetch requests:

I think we should look at fixing this later once that spec question is resolved.  If its a major problem, though, we can always implement a new internal interface for fetch that allows aborting.

The conversation moved to different issues and commits, but there appears to be a spec-defined way to abort fetches / workers:
