Problem statement

• When trying to migrate from 0.5.9 or 0.5.10 to 0.6.0 nightly or alpha, users were ending up with 2 sidestore official sources since the sourceURL was changed from "apps.sidestore.io" to "sidestore.io/apps-v2.json" and sidestore couldn't decide which one to use since it now has 2 official source causing the sources-fetch (swipe-down action on "News" tab to fail with fetch) errors.

Changes

• Since we rebased from altstore-1.6.3 to altstore-2.0.x directly we can ignore the intermediate model versions and migrations xcmapping. So the following models have been deleted to reduce maintenance burden
  • AltStore 12.xcdatamodel
  • AltStore 13.xcdatamodel
  • AltStore 14.xcdatamodel
  • AltStore 15.xcdatamodel
  • AltStore 16.xcdatamodel
• We are now doing a direct migration from AltStore 11.xcdatamodel to AltStore 17.xcdatamodel via custom migration mapping called "AltStore11toAltStore17.xcmappingmodel".
  • Within this we define the following custom migration policies (via custom migration policy classes):
    • StoreApp11To17MigrationPolicy.swift
    • Source11To17MigrationPolicy.swift
  • In StoreApp11To17MigrationPolicy we now move the [AppVersion] list from storeApp._versions into storeApp._releaseTrack._releases and set the storeApp._releaseTrack._track as stable while creating(establishing) relationships for StoreAppToStoreApp entity mapping.
    • This change facilitates the migration to newer ReleaseTracks feature
  • In Source11To17MigrationPolicy we now change the value of sourceURL if it is apps.sidestore.io to sidestore.io/apps-v2.json so that only 1 source ends up into the migrated database for the official sidestore source.
    • With this change, there won't be 2 official source after migation and no more confusion when saving to database upon first start of the sidestore after migration.

Key Highlights

• After merging this PR we should be good to go for next release

Tests Performed:

• install 0.5.9 built via xcode from source on simulator iOS 18.2 (iPhone 16 Pro).
• install 0.6.0 from coredata-migration-fix branch on top of existing 0.5.9 which will be treated as an update.
• Expectations:
  • No double sources for the sidestore official source in sources tab
  • No errors when refreshing/fetching (swipe down) on the News tab or MyApps tab.
  • in-app update delivery(install) retains the above 2 Expectation promises.
• All tested to be working as expected.
