1. This service is shutting down soon. Sent on success responses, triggers UI like "The old Firefox Sync service is shutting down soon. [Learn more]." 2. This service is shutting down really soon. Sent as a failure response. Triggers UI like "The old Firefox Sync service is no longer available. To continue syncing you need to take action. [Learn more]."

Includes some small fixes to head_http_server to avoid mixed-return warnings. Strings open to change. Tests verify that we notify (which will hit the UI code), adjust sync intervals in the hard-eol case, and throw or not as we always have for error responses.

(In reply to Gregory Szorc [:gps] from comment #4) > Please don't hesitate to badger me about reviews. Thanks! > Shouldn't we check xwa on *every* response? In theory, yes, we should have a response filter that does something with X-W-A on every response. (It's hilarious to have a messaging channel in the spec that the client does absolutely nothing with.) But here we're just (mis-)using X-W-A as a structured side-channel. Given that I want to uplift this, and I don't want to take the risk of breaking error handling elsewhere, I took some pains to be less invasive than I could have been. In this case, I'm mainly targeting _fetchInfo (that is, we check for this once per sync), not altering whether an error is thrown, and only checking in the cases where we think this kind of error might be returned -- stable successful fetches (soft EOL), 513 (the new error code; hard EOL), and 404 (because we've seen that bug before, and perhaps that'll be the state we hit during decommissioning).

On the subject of strings: These messages are to be trapped in amber before we implement Firefox Account-aware messaging (Bug 908465). Some clients will be far enough behind that they'll see these, not the new stuff. Early in the transition to Sync.next, we'll be encouraging migration via storage indicators and FxA-aware messaging. The two services will run concurrently with no EOL messaging. The two indicators in this bug will come into play when we begin a firmer ramp-down (soft-eol), and then when we stop providing service (hard-eol), and will be seen by two groups of people: * Those who are sticking with Fx 25-28 (say) for some delierate reason, or who have fallen out of automatic updates somehow. * Those laggards who might have upgraded Firefox enough to get FxA on another device, but not this one, before the EOL period begins -- they won't get the storage indicators or FxA-aware messaging, but all they need to do is upgrade for things to start working (until hard EOL, of course). As such, the goals are: * Include a Learn More link that will advise the user to upgrade. We might want a SUMO page for this, rather than just hitting getfirefox.com. * Have vague enough wording that we don't trap the wrong sentiments in amber, should our plans not survive contact with the enemy. * Lesser: be general enough that other Sync service providers (e.g., ownCloud) could start sending these responses and not confuse the heck out of users.

Madhava: can you suggest someone to review my wording for this and the equivalent on Android? Ordinarily I'd bug Ian, but he's afk for a couple of days, and I know he has a full plate…

Decided to change the strings to say "Your": warning.sync.eol.label = Service Shutting Down warning.sync.eol.description = Your Firefox Sync service is shutting down soon. Upgrade Firefox to keep syncing. error.sync.eol.label = Service Unavailable error.sync.eol.description = Your Firefox Sync service is no longer available. You need to upgrade Firefox to keep syncing. This makes more sense from two directions: * For self-hosted users, it acknowledges that it's not "the" service. * It implies that there's a different (new?) Sync service that you get when you upgrade. Also clearing info, 'cos Madhava's on vacation.

Just the string changes; otherwise the same as v1.

This reuses existing strings.

One day I'll qref every time.

... and now with a change to have the test work without the dynamic port/URL stuff.

Comment on attachment 796945 [details] [diff] [review] Patch for Aurora and Beta. (no strings) v3 Review of attachment 796945 [details] [diff] [review]: ----------------------------------------------------------------- Please be sure this is marked for manual QA verification, especially since we're presumably landing this so late in a Beta cycle.

(In reply to Gregory Szorc [:gps] from comment #15) > I'm pretty sure localizers won't like seeing "Firefox Sync" and "Firefox" > inline. Shouldn't these be &brandShortName or something like that? Might > want to get additional review from somebody who knows more. I did this for three reasons: 1. The rest of the file is full of them. 2. More broadly, "Firefox Sync" is a proper noun, not a brand element; even if you're running Nightly it's called "Firefox Sync". 3. As I understand it, using entities in property files is a pain in the ass. But I feel your pain.

N.B., I do need to rework the patch to catch the "upgrade Firefox" inclusion!

Added a Metro-compatible way of getting the app name, and format it into the description string. Fixed whitespace, introduced a pseudo-constant for the default URL.

We'd rather not take any risk in FF24 at this point - can you speak to the benefit of taking this patch one release sooner? How many releases until this is fully deprecated?

How many releases until > this is fully deprecated? It depends on a number of things: the release date for a system that replaces Sync (could be December), the rate of adoption of that system (they'll overlap for a few releases), and the rate of user upgrades across all Firefox versions. I *hope* the number of users who will still be using Fx24 when we start the EOL process will be small, so if you're tightening the risk crank, that's totally fine by me.

QA will hang on for final decision on where this is going to land. Then I will be bugging :nalexander and :rnewman about test requirements for this bug/patch...

That patch needed to be adjusted for Aurora. https://hg.mozilla.org/releases/mozilla-aurora/rev/b0bc9c628c80

:rnewman and :gps https://bugzilla.mozilla.org/show_bug.cgi?id=908461#c16 Do you have some specific STRs or QA requirements for this manual testing? What would you like to see for Nightly, Aurora, Beta?

This is not something that can be manually tested until there's server support -- Bug 908467. Shouldn't be a lot of work. Behavior will be something like "when the server sends a hard EOL, show this; when it sends a soft EOL, show this other thing, verify that sync intervals change accordingly". I'll help you thrash out a more detailed plan when we have server support.
