bug 568728 moved nsAddonsRepository.js to AddonRepository.jsm, and updated package-manifest.in but not removed-files.in. Anyone updating to 4.0b1 using a complete update (eg from 3.7a4 & older, or the partial fails from 3.7a5) will end up with both copies of the file. Simple enough fix to http://hg.mozilla.org/mozilla-central/file/default/browser/installer/removed-files.in, but we need to know if this blocks 4.0b1.

I think it does - ending up with both files here would be pretty bad, I think.

Add components/nsAddonRepository.js to removed-files.in In terms of the Addon Repository code, and the code using it, I can't think of a way where having both files would break things; nsAddonRepository.js would just not be used anywhere. However, I am not entirely sure if there is another way having both files breaks things. So, hopefully the patch can land for beta1.

Dave Townsend will be able to set us straight here. This isn't user data, right, this is just our code?

I'm pretty sure beta1 would be good without this, nightly users haven't complained about any problems either, from what I heard. We had the same bug in SeaMonkey, we probably will take it as ride-along in build2 of our 2.1a2, I guess it might be best for Firefox to also consider it not actually blocking, i.e. triggering a respin, but good for a ride-along if a build2 is needed. :)

Comment on attachment 454818 [details] [diff] [review] Patch There is actually no problem with having both of these files present, they should not conflict with each other and at least in Firefox neither is actually in use right now.

Thanks for jumping on this Ben. Landed on trunk: http://hg.mozilla.org/mozilla-central/rev/195e0f1d0bf1 Landed on relbranch: http://hg.mozilla.org/mozilla-central/rev/724856797907
