886587 - Remove profile migrator

Status: RESOLVED FIXED

(Firefox for Android Graveyard :: Data Providers, defect)

Description

[:Margaret Leibovic]

It's been almost a year since we shipped Fennec native, I think it's time to retire the XUL profile migrator.

gcp, do you see any reason to keep it around?

Comment 1

[Nick Alexander :nalexander [he/him]]

This will also allow us to remove an ugly bit of Makefile.in -- the logo.png copying.

Comment 2

[Gian-Carlo Pascutto [:gcp]]

Not really. I suppose people still stuck on XUL aren't going to get an update :-)

There's a small part that does some moving around of profiles on the sdcard to internal storage, that was probably a more recent bug and something you might have to keep for a bit longer.

Woo hoo! Hack all the thingz !!

First cut patch ... let me know if I took out something we like :-)

I've left that critical bit from bug 878674 as a standalone module ProfileMigrator.java ... we might could move that into GeckoApp ... we'd have to move the CLEANUP_VERSION prefInt() also ... not sure what to do with any leftover ProfileMigrator.xml file though ... ignore it?

You'll need to remove the places.sqlite in the assets dir that the test is using as well.

Comment 6

[Gian-Carlo Pascutto [:gcp]]

Also, you need to remove SetupScreen and associated assets, ProfileMigrator is AFAIK the only thing using it.

>not sure what to do with any leftover ProfileMigrator.xml file though

You mean inside shared_prefs? I wouldn't particularly bother personally. Though given that there's still a cleanup pass left over you could also delete them.

This is looking good to me, but let's get rnewman's feedback on the sync bits. You can also let gcp do the honors of the final review :)

Pity we don't already have tests for the cleanup part of migration. Still, what's done is done!

Note that anything under m/a/b/sync needs a corresponding pull req in a-s (and also an import of BrowserContract, which I'll take care of).

Hooray for killing code!

Ditto.

Flagging for QA and documentation.

Ok ... with all the work that rnewman did, and this patch, everything should be taken care of, except (iiuc) some cleanup code into GeckApp's DeferredCleanupTask() to remove the old places.sqlite DB which I thought to do in a follow on patch.

Please see previous comments. You need to remove SetupScreen and assets, and the places.sqlite in assets that's used for tests (it might be in the assets zipfile).

>some cleanup code into GeckApp's DeferredCleanupTask() to remove the old places.sqlite DB which I thought to do in a follow on patch.

There is no need to do that, because ProfileMigrator will either have already removed it or the user won't have had a previous version anyway. You need to remove the one used for the test you removed.

nit: use the same modifier structure as the other constants above.

Removing SetupScreen and friends helped with one of my tickets, so I removed them in Bug 895670.

[Gian-Carlo Pascutto [:gcp]]

Ah great, then it's only the assets/places.sqlite.zip that has to go. r+ with that fixed.

I saw that |Removing SetupScreen and friends| had been done but I didn't credit nalexander, so thanks for that :)

As for the |places.sqlite| bit, it took a second for my brain to catch up to what we were talking about ... this should do it  :-D
