Optimize ProfileManager in several ways:
- Refine control over objectWillChange
- Observe search separately
- Store subscriptions separately (local, remote, search)
- Fix multiple local updates on save/remove/foreground (updating
allProfiles manually)
- Update the library with more optimized NE reloads
- Cancel pending remote import before a new one
- Yield 100ms between imports
- Reorganize code
Extras:
- Only use background context in provider repositories
- Externalize tunnel receipt URL, do not hardcode BundleConfiguration
- Improve some logging
Self-reminder: NEVER use a Core Data background context to observe
changes in CloudKit containers. They just won't be notified (e.g. in
NSFetchedResultsController).
Fixes#857
- Address further restrictions on actor-isolation by using `nonisolated`
on:
- Combine subjects
- Core Data context/controller
- Blocks
- In previews using inline `@State`, create a custom view instead
- Use `@retroactive` in l10n extensions
- Fix compile error in WireGuardKit
Countries are filtered through the latest servers list. If a country is
chosen, the countries picker only lists the currently selected country,
because there are no servers from other countries.
Update the library to prefetch the available countries per category.
Also, improve filters by constraining related fields:
- Pick countries from the filtered category
- Pick presets from those available in the currently filtered servers
Closes#705
