Only exposes QUERY_PARAM and CLIENT_ID
Requires opt-in per <a> tag.
Only done for destinations going to the page's source or canonical origin.

@zhouyx please take a look
CC @rudygalfi I went ahead and implemented this :)

One thing I don't understand. We still do lazy initialization. What I see here is that this.setAsync_('CLIENT_ID... here is called no earlier than this.set_('CLIENT_ID.... Would this work as expected?

@zhouyx Could you rephrase your question? I'm not sure I understand.

This is intended to only provide a CLIENT_ID into a link if there was another mechanism that previously requested it.

zhouyx · 2016-10-17T19:34:53Z

I see, I thought we would need to wait and replace the URL in all cases.
So we are not replacing CLIENT_ID if we don't have it at that moment, would it be normal that url replacement will fail because we never wait for anything?

cramforce · 2016-10-17T19:42:34Z

Replacement happens on click, while the other mechanisms (analytics) load on page view, so they will probably have run by the time of the click.

+      if (!clientIds) {
+        return null;
+      }
+      return clientIds[dev().assertString(scope)];


don't quite understand what's the scope here. Is it always the same as what we set clientIds[scope above?
Would it be possible to getclientIds[scope] = null here?

scope is the param passed of CLIENT_ID(someScope). If the scope is the same, the client ID is the same, which should be what is achieved here. The return value of this statement is undefined if no async request for the client id was made.

where is this used?

Line 647. I'll add a comment as to what this is for.

- Only exposes `QUERY_PARAM` and `CLIENT_ID` - Requires opt-in per `<a>` tag. - Only done for destinations going to the page's source or canonical origin. Fixes ampproject#4078

        }, consent);

+        if (!clientIds) {


Why not just initialize it above? It's just one object.

Please let me have my premature optimizations :)

+    const supportedReplacements = {
+      'CLIENT_ID': true,
+      'QUERY_PARAM': true,
+    };


We could reuse the same supportedReplacements by settings its values to false.

Yeah, it also isn't actually used like that, i think. I don't care about allocation on click :)
