First of all, add country flags assets. Then, present provider server
selector:
- From installed profile view, specifically from a button with the flag
of the current country
- From profile context menu
- On toggle profile when no server is selected
Closes#711
- Drop logic behind connection button tasks, let the library handle
concurrency
- Drop AppContext observation of saved profiles for reconnection, let
save() actively decide
- NETunnelStrategy and NETunnelManagerRepository are now a single entity
- Avoid flickering when toggling same profile
Currently, NEProfileRepository decodes profiles from ALL NE managers on
any update. This is undesirable considering that:
- Profiles are only _added_ by the app
- Externally, profiles can only be _removed_
Therefore:
- Observe the initial managers to decode the initial profiles from them
- Publish values manually on save/delete (to ProfileManager eventually)
- Observe the subsequent updates for when a profile is removed
externally, i.e. its ID doesn't appear in managers
Fixes#741
Resolve some flickering and state inconsistency due to overextended
observation of VPNProviderManager. Narrow down its scope to
VPNProviderServerView.
The downside of that, for now, is that servers are loaded "lazily late",
but this flow will make region selection from home easier.
Finally, show filters in popover on iPad.
Improve rendering and work around some SwiftUI bugs, e.g. with .menu
Picker on iOS (use .navigationLink instead).
Here goes the hierarchy bottom-up:
- ProviderPicker: a Picker wrapper built around ProviderManager
- ProviderContentModifier: adds a ProviderPicker on top and replaces the
content with a set of provider selectors when a provider is selected
- VPNProviderContentModifier: wrapper for ProviderContentModifier that
adds a VPN server selector
- OpenVPNView: provides a view of specific OpenVPN settings, and adds a
credentials selector to the provider/server selectors provided by
VPNProviderContentModifier
When e.g. a OpenVPNModule is created without a configuration and a
provider/server is then selected, the ProfileProcessor class serializes
the profile with the provider configuration injected. When the module is
re-edited, we can see the provider server configuration in the module
after selecting "None" as provider.
Instead, validate the provider modules in ProfileProcessor, but generate the provider configuration on the fly in the tunnel.
Update library to allow optional VPN configurations. This in turn allows
a module to be used with a provider, where the configuration is
generated on the fly.
- [x] NE managers were not deleted when unable to be decoded to a
profile
- [x] Keychain items were not deleted on profile removal
- [x] Perform clean-up on app launch
- [x] Perform clean-up on app active
Prematurely merged as #727 then reverted, this is the complete PR.
Profiles are being maintained in two places:
- Core Data
- NetworkExtension
Core Data is redundant for local profiles, so make NetworkExtension the
only source of truth.
Helps with automation. Install the VPN configuration before persisting a
profile, so that the 1:1 reference with OS settings is maintained.
Likewise, uninstall the VPN configuration after removing a profile.
This before-save hook also resolves a problem with multiple imports,
where multiple VPN permission alerts coalesce if no VPN configuration is
installed. Now the first import waits for the permission synchronously.
Fixes#618
