@scheib, I added some rationale text for canShare for #159 ... would you mind taking a look and let me know what you think?

Spec: https://w3c.github.io/web-share/#share-method If a share() request is active when share() is called again, the new share request fails immediately. w3c/web-share#113 In content shell, the OS-integration for the share service is not present. Instead of crashing in tests, we report a not implemented error. WPT web-share/share-sharePromise-internal-slot.https.html now passes (It previously crashed.) Protocols other that http and https are no longer supported by share() or canShare(). w3c/web-share#174 canShare is being discussed in w3c/web-share#177 Bug: 1002337, 1002514, 1131755 Change-Id: I4ec9f6eb03373fd5c6db1881df906a8df36ca4ff

Thank you - this addresses #159 well. Text explaining why to use canShare looks good to me.

Pinging again 👋 I'd like get this merge so we can move the spec to CR.

index.html

+          The choice to use string literals instead of an [=enumeration=] is
+          deliberate. Doing so allows implementers to gracefully support future
+          {{ShareData}} member values, while also giving the user agent the
+          ability to disable sharing those members if needed.


Should this mention whatwg/webidl#893 or whatwg/webidl#491?

No. If something changes in WebIDL, then it should be adopted. whatwg/webidl#491 should be closed anyway - it's no longer relevant.

Should this be marked as historical if we think this is a broken approach?

Only if we are not going to ship an alternative - but I don't think anyone plans to.

Only if we are not going to ship an alternative

Are going to?

Oops, yes... there is no plans for any engine to ship anything different. Let's just ship this and be done for now. If we need a new method, we can add it when there is demand for it.

I don't think Gecko would want to ship anything proven to be broken as a sole solution 🤔

cc @annevk, context: #108 (comment)

That's ok, but if we can't shift the other implementers then we need to make a process call here (i.e., Mozilla can "formally object" and we figure it out from there).

We have two engines that already ship .canShare() already (and have now for over a year).

I think it depends on real world usage of canShare.

You are right, that too... however, we (you and I) are kinda limited in that we can't actually get that data.

We are at an impasse here :( without input from other implementers willing to change (or even respond to issues), I don't know what we can do 😭

How can we get diff preview as other w3c repositories have?

We might not have had .pr_preview enabled when the PR was created a long time ago... I'll see if I can get it working.

marcoscaceres · 2021-08-09T01:48:31Z

PR preview is back 🎉

marcoscaceres · 2021-08-18T07:12:50Z

Ok, sent a PR to remove "tentative" from the canShare() tests. The tests all pass in WebKit, except 1 that I need to look into.

marcoscaceres · 2021-08-20T01:48:41Z

I'm going ahead and merging this as this matches two shipping implementations, and this is been sitting for nearly a year. I'm happy to continue to revise canShare() and even send patches to various engines if we want to improve it in various ways - so long as things remain backwards compatible.

I'll also make another attempt to update the Gecko patch.
