Currently it's impossible for another spec to know if an extendable event is in progress, or what the result was afterwards.

I intended to just mark some things as "export", but tried to tidy up the useage along the way.

  • ExtendableEvent's extend lifetime promises is now exported.
  • ExtendableEvent now has a timed out flag, which makes the user agent timeout a little more formal and detectable by other specs.
  • ExtendableEvent now has an active 'getter', which indicates the event is in progress.

If this is ok, I'll make the same changes in v1.

This has made it possible to monitor the progress of extendable events in other specs http://localhost:8080/background-fetch/#background-fetch-update-ui-event-update-ui.

I like how it's referenced in the Background Fetch spec and also how it makes it easier to read the spec. Let's backport it to V1 too.

For my own reference, here's an easy way to lift changes from the living spec to v1:

git diff master -- docs/index.bs | patch -p1 docs/v1/index.bs

(assuming you're on a feature branch based on master)
