Refactor SettingsBase to use primary constructor, improve cache (#1147)
* Refactor SettingsBase to use primary constructor and improve cache selection Refactored SettingsBase to use a C# primary constructor and updated the logic for selecting the appropriate IBlobCache. The new logic prioritizes explicitly created caches, falls back to CacheDatabase caches, and finally creates an in-memory cache if a serializer is available. Improved error handling and exception messages for missing caches. * Update CI workflow to run PRs on main branch The CI workflow now runs on pull requests targeting the main branch. Added global environment variable for productNamespacePrefix and set build configuration to Release. * Update src/Akavache.Settings/SettingsBase.cs Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Update .github/workflows/ci-build.yml Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Add test coverage for SettingsBase cache fallback logic (#1148) * Initial plan * Add test coverage for SettingsBase fallback logic - Tests verify fallback to CacheDatabase.UserAccount when no explicit cache configured - Tests verify settings persistence across instances - Tests demonstrate the fallback priority logic - Some edge case tests remain challenging due to static state interference Co-authored-by: ChrisPulman <4910015+ChrisPulman@users.noreply.github.com> * Complete fallback test coverage with passing tests - All new tests pass successfully - All existing tests continue to pass (18 total) - Tests validate CacheDatabase fallback when no explicit cache configured - Tests validate settings persistence across multiple instances - Removed flaky tests that had static state interference issues Co-authored-by: ChrisPulman <4910015+ChrisPulman@users.noreply.github.com> --------- Co-authored-by: copilot-swe-agent[bot] <198982749+Copilot@users.noreply.github.com> Co-authored-by: ChrisPulman <4910015+ChrisPulman@users.noreply.github.com> Co-authored-by: Chris Pulman <chris.pulman@yahoo.com> * Refactor SettingsBase cache lookup to use explicit LINQ filtering (#1149) Co-authored-by: copilot-swe-agent[bot] <198982749+Copilot@users.noreply.github.com> Co-authored-by: ChrisPulman <4910015+ChrisPulman@users.noreply.github.com> Co-authored-by: Chris Pulman <chris.pulman@yahoo.com> --------- Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> Co-authored-by: Copilot <198982749+Copilot@users.noreply.github.com> Co-authored-by: ChrisPulman <4910015+ChrisPulman@users.noreply.github.com> Co-authored-by: Glenn <5834289+glennawatson@users.noreply.github.com>
