It seems we should keep databaseDirectoryRelativeToRoot to provide version/top/opening.

Thanks for fixing this!

Can we pass a const ClientOrigin& here?

Shouldn't we keep version/top/iframe structure and do the migration of folders version/iframe/top?

It could be a one liner.

Maybe we should rename to upgradeIfNeeded?

It does not seem consistent with: "If IndexedDB does not have version directory, the origin directory structure is correct".
So we are moving the correct ancient to the incorrect but consistent with v0/v1? Should we do the reverse and move back v0/v1 to correct?

Also, given reverseOriginForDirectoryIfPossible is destructive, we probably only want to execute it once.
I do not see what guarantees that oldVersionDirectory will not exist anymore after calling reverseOriginForDirectoryIfPossible.
Is it overkill to increase the IDB database version?

Usually we do only file changes in background thread. I guess this is fine since it will only happen once.

Unnecessary.

Sure, I will make a change.

Np!

Sure, I made a mistake in thinking that v0's origins are correct.
My new plan is to reverse the wrong origins in v1, and we can keep the structure here.

Sure.

We don't actually upgrade here, but just add a new v0 directory; we do the upgrade (adding v1/ and moving files to v1/) in IDBStorageManager::migrateOriginData.

I made a mistake here by thinking only ancient files have correct origin: actually ancient files and v0/ files are correct; only v1/ files are not. I will make the according changes.
Yes, it seems overkill to increase the version (v0, v1, v2), because we are about to migrate data to general storage directory.

I am going to move this to a background thread in network process so the migration can be done in both WebKit and WebKitLegacy.
