Restore CDModulePreferencesV3 to track the history of module prefrences.
This way, excluded endpoints may be saved globally to Core Data as a
starting point. Then in Profile.userInfo we only save the relevant
exclusions for the current configuration.
The .excludedEndpoints relationship is therefore moved out of
CDProviderPreferencesV3.
Further refactoring:
- ModuleViewParameters now includes a ModulePreferences observable that
module views can observe
- Tunnel doesn't need access to PreferencesManager anymore (exclusions
are in Profile.userInfo)
Store module preferences in the Profile.userInfo field for atomicity.
Access and modification are dramatically simplified, and synchronization
comes for free.
On the other side, fix provider preferences synchronization by using
viewContext for the CloudKit container.
Fixes#992
Exclude endpoints from OpenVPN modules and providers with the generic
Blacklist<T> observable. Eventually, rebuild the Profile in
PacketTunnelProvider (via DefaultTunnelProcessor) with the applied
exclusions from preferences.
Revisit approach to preferences:
- Module preferences
- Tied to the module and therefore to the parent profile
- Load/save in ProfileEditor on request (rather than on
ProfileEditor.load)
- Provider preferences
- Shared globally across profiles
- Load/save in module view if needed
For more consistency with Core Data:
- Revert to observables for both module and provider preferences
- Treat excluded endpoints as relationships rather than a serialized
Array
- Add/remove single relationships over bulk delete + re-add
- Do not map the relationships, Blacklist only needs exists/add/remove:
- isExcludedEndpoint
- addExcludedEndpoint
- removeExcludedEndpoint
Some clean-up:
- Move the importer logic to OpenVPNView.ImportModifier
- Move the preview data to OpenVPN.Configuration.Builder.forPreviews
- Drop objectWillChange.send() on .repository didSet to avoid potential
recursion during SwiftUI updates
Closes#971
Sort out the increasing mess coming from:
- AppContext*
- Dependencies
- Shared*
by doing the following:
- Keep in the "Shared" folder only the entities actually shared by
App/Tunnel
- Create TunnelContext
- Move AppContext and related to the App/Context folder
- Move TunnelContext and related to the Tunnel/Context folder
- Delete Shared+* extensions, use AppContext/TunnelContext singletons
from the app
- Create a Dependencies factory singleton to create entities in a single
place
- Split extensions by domain
- Make it clear with `func` vs `var` when a dependency method returns a
new instance
