Update stranded "4
.0a1pre" users to a valid nightly
For a short while after the 1.9.0 branch was cut "Minefield" nightlies were called 4.0a1pre. The trunk was later renumbered 3.6a1pre and stranded users who did not manually download a new version since client updates will not down-rev people. We currently appear to have about 7K of these stranded users, about the same number as those using the active trunk 3.7a1pre Minefield builds and nearly double the number using the latest Namoroka nightlies. We need to prepare update snippets to move these people onto a supported nightly, both for their security and to help them fulfill their apparent intention to help us test. To which build do we direct them? Beltzner says trunk nightlies because that's what they were originally using. I argue Namoroka nightlies because that's where we most need the help testing, and I believe that matches what happened to then-trunk nightly testers when we cut the 1.9.2 branch. Beltzner wins if he doesn't buy my arguments. Either way the update snippets will have to say some version higher than what they've currently got (e.g. "4.0a2pre") but can point at an existing complete mar update file. We'll have to test that of course, but should work in theory.

The number of people we can actually reach is probably much less than 7K, more like 2K. Still worth looking into though. If you dig into the AUS metrics, limiting to Product=Firefox, Version=4.0a1pre, and averaging over Sept 1 to Sept 9, then there are 7813 users. Of those 5582 (71%) are on the default channel, and the rest on the nightly channel. The most common buildID's are nightly: 2008050802 197 2008051003 1758 2008051302 134 default: 2008031002 1233 2008031602 683 2008041102 2803 The first group may be afflicted by a problem with the updater, I'll check if they're stuck or not. If the updater was working then I'd expect almost all of them to be on the same build, because we stopped offering updates to 4.0* users long after the version was reduced. For the "default" builds, the channel-prefs.js is setting the channel to default, so that was an omission in the mozconfig (not specifying a channel and so falling back to the default in the build system). Not sure we can convince AUS to talk to them without affecting other people who compiled their own builds.
(In reply to comment #1) > The number of people we can actually reach is probably much less than 7K, more > like 2K. Still worth looking into though. Given how small this group is, can you clarify the importance of this? Is there something specifically important about these orphaned 4.0*pre users? Otherwise, could we just reopen bug#383676 and deal with these like other orphaned users, as time permits?
This group is a nice test-case for the work that we will eventually want to do for other stranded groups. It's a single version ID, there's zero risk of them *wanting* to stay there for some reason (since the version doesn't correspond to a specific set of functionality, just a point-in-time naming glitch - people 'orphaned' on 2.0.0.x or even 3.0.8 might be intentionally staying there for some reason) and my hope is that it would be an easier problem to solve than "recover all orphaned users." Is that helpful, John? Do you foresee this being a significant amount of work, where we should be careful to pick only the highest value target? Or is this reasonable as a scoped-down trial balloon?
Looks like no one is commenting here, last question was for joduinn. joduinn - does this look like something that we want to work on soon?
Daniel, do we have some current numbers for this category of user?
Assigning to joduinn for prioritization.

Or is this > reasonable as a scoped-down trial balloon? Scoping down the problem is an excellent reality-check, Johnauth, thanks. It feels like we should focus effort on where the most users are, so I'd like to identify the largest clump of orphaned users, and directly try to upgrade those. By *far*, the biggest clump is on FF126.96.36.199, several orders of magnitude more then are on FF4.0a1. Therefore, as we discussed, I'm going to close this bug as WONTFIX, and have instead opened bug#526409 to track a new MU offer for those users on FF188.8.131.52. Once we do that, we can reevaluate doing another upgrade for the next largest clump of orphaned users. Let me know if I missed anything, ok?

It's true that this is a small number of users, but they're users who want to be nightly users, so they're especially valuable.
Re-opening as we fixed bug 526409 a while ago, and this bug has yet to be resolved. Current ADUs show as many (if not more) people using Firefox 4.0a1pre as using Firefox 3.7a5pre (about 14,000) across all channels. Nick mentions that only about half of those users are on the nightly channel, meaning that some are compiling it themselves (which is odd enough). Anyway - I think we should do an across-all channels unadvertised update that takes: Firefox 4.0a1pre -> latest nightly and also moves them onto a nightly channel.

I think the "compiling it yourself" thing has got to be a red herring: self-compiled builds will only identify as 4.0a1pre if they were compiled between 14-Feb-2008 and 13-May-2008. I still don't understand where this data can be coming from, though: is this blocklist/AMO data, or AUS data? The metrics dashboard is really confusing to me.
I was using blocklist pings
Repeating the data mining I did earlier (comment #1) - using AUS data, limiting to Product=Firefox, Version=4.0a1pre, and reporting the average number of requests over the week ending 2010-04-19. There are about 7700 users on nightly, 7800 on default. The most common buildID's are nightly: 2008050802 895 2008051003 6607 default: 2008031002 1318 2008031602 1500 2008041102 4158 These are all en-US Windows users, about 80% using XP but about 10% each for Vista & 7. There are no buildID's after 2008060602 so I agree with bsmedberg that this is not people compiling themselves (at least not any time recently). Perhaps the increase over time is from some blogs/websites out there pointing to the old builds, basically getting excited that 4.0 > 3.x. The group on nightly we can probably get to easily, in fact I hacked up a test and we don't even need to fake the version to keep the updater happy. For those on default we'll need the AUS changes in bug 534954 (in order to be able to update only default users with version 4.0a1pre) and a custom mar file to update channel-prefs.js. I'd rather do this all at once so I'm going to block on 534954.

This worked for me to test both nightly and default cases, after setting up a mozilla-central-catchup/ as a subset of mozilla-central/ (last two en-US dirs for WINNT_x86-msvc). For realz we'd use a snippet pointing to the custom mar, and those users would go old build --> latest build when mar created --> latest build

Attachment #440253 - Attachment is obsolete: true
This gets us the set of 4.0a1pre users using the nightly channel. Give them mozilla-central for now, but they'll get mozilla-1.9.3 when that branch is cut.

For 4.0a1pre/default, we can address these builds by creating snippets in the release side of the snippet store (ie Firefox/4.0a1pre/BUILD_TARGET/BUILDID/default/). We need an explicit list of buildID's for that, these are the ones with counts >=10 over the last week, which happen to all be WINNT_x86-msvc: 2008030702 2008030802 2008031002 2008031102 2008031402 2008031502 2008031602 2008031702 2008031802 2008040802 2008041102 Then we create a custom mar that updates channel-prefs.js to use nightly. After getting that update they'll go the same path as 4.0a1pre/nightly users.

Still 3k users on default with buildID's like those in comment #17. The mar file had been removed from ftp.m.o by cron'd clean up jobs, restored it with permissions which make that impossible.
Nick, just wanted to verify that the mar is still being offered?
Should be, eg ('scuse the old school url format) https://aus2.mozilla.org/update/1/Firefox/4.0a1pre/2008041102/WINNT_x86-msvc/en-US/default/update.xml That'd get them on nightly then up to latest on the next update. There would have been some period between comment 23 and comment 24 when it wasn't offered but I don't how long that would have been.
I couldn't find any users at all on 4.0a1pre, and the MAR file from here was causing an error in one of our cleanup cronjobs, so I moved it away to ~ffxbld.
In the last 30 days there have been 88358 AUS pings (not blocklist pings) for Firefox version 4.0a1pre. All of them were en-US except for 2 pings for zh-CN. That equates to over 2900 users if each one launched Firefox 4.0a1pre every day which is highly unlikely so the number of users is quite likely higher.
Forgot to mention that a link to the data is in bug 651779.
The current state is that the update offer is up (example url in comment #26) but it points to a channel switching mar which is a 404. I can probably find a copy of the mar, but if they haven't updated while the path has been live for several months what hope can we have they ever will ?
We've seen slow uptake where it takes months for the stragglers to update previously and I think it is best to always have the update available for these users so they can update when the mood strikes them.
I also think we should just advertise this update with 4.0a1pre for the extensionVersion so it will by default not prompt the user. The numbers I provided in comment #28 are for AUS pings so chances are the majority of those users would just get updated.
I'm much less optimistic that users who haven't updated in months ever will, but as long as the number of these hacks is limited it's OK they live on. To fix up people still stuck on default I put the mar file back and added a cron job for ffxbld@stage so that it doesn't go away again. @weekly touch /pub/mozilla.org/firefox/nightly/experimental/bug518508-update-channel/update-channel.mar (In reply to comment #32) > I also think we should just advertise this update with 4.0a1pre for the > extensionVersion so it will by default not prompt the user. We are already doing this for people on default, which delving in the metrics is roughly half of your 4.0a1pre count. If we want to do this on the nightly channel then then bug 651283, or a new bug is where we should do that. This one is complicated enough already.
