<deluan@navidrome.org> * fix: handle URL parsing errors and use atomic upsert in plugin repository Added proper error handling for url.Parse calls in PublicURL and AbsoluteURL functions. When parsing fails, PublicURL now falls back to AbsoluteURL, and AbsoluteURL logs the error and returns an empty string, preventing malformed URLs from being generated. Replaced the non-atomic UPDATE-then-INSERT pattern in plugin repository Put method with a single atomic INSERT ... ON CONFLICT statement. This eliminates potential race conditions and improves consistency with the upsert pattern already used in host_kvstore.go. * feat: implement mock service instances for non-WASM builds using testify/mock Signed-off-by: Deluan <deluan@navidrome.org> * refactor: Discord RPC struct to encapsulate WebSocket logic Signed-off-by: Deluan <deluan@navidrome.org> * feat: add support for experimental WebAssembly threads Signed-off-by: Deluan <deluan@navidrome.org> * feat: add PDK abstraction layer with mock support for non-WASM builds Signed-off-by: Deluan <deluan@navidrome.org> * feat: add unit tests for Discord plugin and RPC functionality Signed-off-by: Deluan <deluan@navidrome.org> * fix: update return types in minimalPlugin and wikimediaPlugin methods to use pointers Signed-off-by: Deluan <deluan@navidrome.org> * fix: context cancellation and implement WebSocket callback timeout for improved error handling Signed-off-by: Deluan <deluan@navidrome.org> * feat: conditionally include error handling in generated client code templates Signed-off-by: Deluan <deluan@navidrome.org> * feat: implement ConfigService for plugin configuration management Signed-off-by: Deluan <deluan@navidrome.org> * feat: enhance plugin manager to support metrics recording Signed-off-by: Deluan <deluan@navidrome.org> * refactor: make MockPDK private Signed-off-by: Deluan <deluan@navidrome.org> * refactor: update interface types to use 'any' in plugin repository methods Signed-off-by: Deluan <deluan@navidrome.org> * refactor: rename List method to Keys for clarity in configuration management Signed-off-by: Deluan <deluan@navidrome.org> * test: add ndpgen plugin tests in the pipeline and update Makefile Signed-off-by: Deluan <deluan@navidrome.org> * feat: add users permission management to plugin system Signed-off-by: Deluan <deluan@navidrome.org> * refactor: streamline users integration tests and enhance plugin user management Signed-off-by: Deluan <deluan@navidrome.org> * refactor: remove UserID from scrobbler request structure Signed-off-by: Deluan <deluan@navidrome.org> * test: add integration tests for UsersService enable gate behavior Signed-off-by: Deluan <deluan@navidrome.org> * feat: implement user permissions for SubsonicAPI and scrobbler plugins Signed-off-by: Deluan <deluan@navidrome.org> * fix: show proper error in the UI when enabling a plugin fails Signed-off-by: Deluan <deluan@navidrome.org> * feat: add library permission management to plugin system Signed-off-by: Deluan <deluan@navidrome.org> * feat: add user permission for processing scrobbles in Discord Rich Presence plugin Signed-off-by: Deluan <deluan@navidrome.org> * fix: implement dynamic loading for buffered scrobbler plugins Signed-off-by: Deluan <deluan@navidrome.org> * feat: add GetAdmins method to retrieve admin users from the plugin Signed-off-by: Deluan <deluan@navidrome.org> * feat: update Portuguese translations for user and library permissions Signed-off-by: Deluan <deluan@navidrome.org> * reorder migrations Signed-off-by: Deluan <deluan@navidrome.org> * fix: remove unnecessary bulkActionButtons prop from PluginList component * feat: add manual plugin rescan functionality and corresponding UI action Signed-off-by: Deluan <deluan@navidrome.org> * feat: implement user/library and plugin management integration with cleanup on deletion Signed-off-by: Deluan <deluan@navidrome.org> * feat: replace core mock services with test-specific implementations to avoid import cycles * feat: add ID fields to Artist and Song structs and enhance track loading logic by prioritizing ID matches Signed-off-by: Deluan <deluan@navidrome.org> * feat: update plugin permissions from allowedHosts to requiredHosts for better clarity and consistency * feat: refactor plugin host permissions to use RequiredHosts directly for improved clarity * fix: don't record metrics for plugin calls that aren't implemented at all Signed-off-by: Deluan <deluan@navidrome.org> * fix: enhance connection management with improved error handling and cleanup logic Signed-off-by: Deluan <deluan@navidrome.org> * feat: introduce ArtistRef struct for better artist representation and update track metadata handling Signed-off-by: Deluan <deluan@navidrome.org> * feat: update user configuration handling to use user key prefix for improved clarity Signed-off-by: Deluan <deluan@navidrome.org> * feat: enhance ConfigCard input fields with multiline support and vertical resizing Signed-off-by: Deluan <deluan@navidrome.org> * fix: rust plugin compilation error Signed-off-by: Deluan <deluan@navidrome.org> * feat: implement IsOptionPattern method for better return type handling in Rust PDK generation Signed-off-by: Deluan <deluan@navidrome.org> --------- Signed-off-by: Deluan <deluan@navidrome.org>
