I noticed that it is possible for a syncGUID to get generated twice during some install scenarios.

I /think/ it reproduces for non-restartless add-ons only:

1) Install add-on from AddonInstall. In the onInstallEnded, the addon.syncGUID is defined as one thing.
2) Restart the application
3) The add-on actually gets installed and syncGUID is regenerated.

I would expect the syncGUID from the first run to get carried over.

This isn't a deal-breaker: Sync will reconcile the different syncGUIDs as things are synchronized. But, it is annoying.

I'll address this as a follow-up to add-on sync.

I think you just need to add syncGUID to here

Reuse syncGUID, v1

Adding the syncGUID field to importMetadata seemed to do it!

I verified the new test code in test_install.js failed without the change to XPIProvider.jsm applied. test_bootstrap.js worked both before and after (I think that makes sense).

My biggest concern with this patch is that I don't have enough test coverage. Is there anywhere else I really need test coverage?

do_check_neq expects two arguments, I guess this is just checking it isn't undefined but be explicit about it

Pushed to inbound with extra null argument to do_check_eq() added:

Reuse syncGUID, v2

This is the actual patch that was committed. Adding as attachment because I'm requesting approval for Aurora. I would like this merged to Aurora because it improves the add-on sync experience and reduces the potential for bugs due to bug 710448.

[Triage Comment]
Because of where we are in the cycle, and the possibility for data loss as outlined in 710448, I'm approving for Aurora.

gps: is there anything to verify here?
Comment 10 User image Gregory Szorc [:gps] (away until 2017-03-20) 2012-01-19 11:37:22 PST
Tracy: This was really an internal optimization. I'm not sure there is an easy way to verify this beyond verifying the Add-on Manager xpcshell tests pass.
