1298503 - Serve 48.0.2 updates to Windows users with "(nowebsense)" in update URL

Status: RESOLVED FIXED

(Release Engineering :: Release Requests, defect, P1)

Description

[David Durst [:ddurst]]

Currently, Windows (32bit or 64bit) users who have WebSense installed will encounter a startup crash if they update to 48 (bug 1294650).

To mitigate this, a hotfix has been developed (bug 1298404) to indicate the presence of WebSense as best we can detect, for clients running Firefox 39-47 on Windows. This hotfix will change the app.update.pref url to be: https://aus5.mozilla.org/update/6/%PRODUCT%/%VERSION%/%BUILD_ID%/%BUILD_TARGET%/%LOCALE%/%CHANNEL%/%OS_VERSION%(XXX)/%SYSTEM_CAPABILITIES%/%DISTRIBUTION%/%DISTRIBUTION_VERSION%/update.xml

where (XXX) will be either (websense) or (nowebsense).

(websense) should only be permitted to update to 47.0.x.
(nowebsense) should be permitted to update to 48.x.

As said in bug 1298404, this should not go live today. We need to have QE signing off this.

My expectation is that Jordan will be taking care of this. Feel free to re-assign if that's wrong.

14:39:18 <jlund> lizzard: heya :) - re: bug 1298503, where do we stand? do you know if this is still required and what the ETA is that it will used?
15:13:49 <lizzard> jlund: Sylvestre commented, we sholud have QE signoff first, then I think sylvestre’s request to go live. 
15:15:15 <lizzard> i think there was a bug in the hotfix found this morning or last night.  So QE will test again tonight and hopefully will be able to sign off. 
15:15:23 <lizzard> But we aren’t quite there yet.
15:16:03 <jlund> lizzard: okay. I'm off in a few hours and it would be good to have more than one pair of releng eyes on the balrog rule that will be required for this.
15:16:14 <jlund> so it sounds like tomorrow is when we will need the rule?
15:16:19 <jlund> at the earliest?
15:18:08 <lizzard> likely softvision will test tonight and then sylvestre would be looking again in his morning…. so as early as then

ftr: I have not added a rule yet for this. this will need coordination of what the final hotfix that sticks will be and how it affects the OS_VERSION string. It would be good to get multiple eyes on this. Will check first thing in the morning on status

Adjusting the desired target based on the target audience of the hotfix

Important note that Mac/Linux users won't have the "(nowebsense)" mark but should continue to receive updates.

Comment 6

[Justin Wood (:Callek)]

Here is the details as I understand it:

# 1 - Update rules for release-cdntest [or maybe new release-websensetest?] so we can QA this before we ship it to users
# 2 once #1 is done, we can apply the same rules to "release" channel users.

For both sets:
* Users with (nowebsense) on *all* windows OS's get updated to 48.0.2 (unless they would have hit a prior watershed).
* Users without "(nowebsense)" on windows will get updated to 47 (unless they would have hit a prior watershed)
* Users on all other OS's will update as they would have prior to this hotfix shipping, thereby completely ignoring the hotfix in rules.
* We're not targetting any beta users with this hotfix/websense rule magic.

Is my understanding correct/valid?

Comment 7

[:Felipe Gomes (needinfo for replies!)]

LGTM, but bhearsum should confirm

Comment 8

[Jordan Lund (:jlund)]

comment 6 is as ben described it to me.

I'll repeat and rephrase to make sure we are on the same page.

* all windows users, we are whitelisting the windows users who have explicitly have the hotfix *and* their OS_VERSION includes the 'nowebsense' string. The other windows users: the ones who haven't got the hotfix yet or who do have the hotfix but also have websense, will continue to get the latest 47 release.
* all other platforms are unaffected
* Usual watersheds apply

This looks like a great summary (I will reuse the content for the channel meeting :p)

[Sylvestre Ledru [:Sylvestre]]

And to detail more, once we have a websense fix/workaround/block in the product, we will be able to enable all updates.
