John Colvin	4f7d77420c	Fix build scripts so they propagate the exit code back to the shell I noticed this was broken because launch.json configurations would still start the debugger even when the preLaunchTask (build) failed!	2024-07-09 15:14:30 -04:00

John Colvin	a62ea64c5e	build: Copy libspark to all dotnet dirs in single cmake target This is cleaner than the previous impl, which used separate build targets to copy libspark to "net7.0", and "net7.0-windows" (dirs). Note: I decided to clean this up now because I'm about to upgrade the new DataStream WebApp to net8.0, and did not want to add yet another build target to copy libspark to "net8.0".	2024-07-09 15:14:29 -04:00
John Colvin	450773f588	fix: Parse ServerAddress as normal string The "JsonValueOrArrayConverter<T>" doesn't work the way I thought it would.

John Colvin	e1526e25a7	cleanup: Fix numerous build warnings in DataStreamSuite Nearly all warnings were due to nullability issues, since the concept of nullable reference types did not exist when the DataStream code was originally written. * PubSubClientMessage - Normalize indentation/whitespace - Fix some typos - Address nullability issues to fix build warnings - Modernize code * Compression related files - ZipEntry - ZipFile - ZipInputStream - TarHeader * RemoteMessage - make 'message' nullable to resolve warnings elsewhere (in calling code) * PubSubSingleTagStateEvent.cs * PubSubMessageReactor * PubSubState * SystemHeartbeatPublisher * SystemStatsPublisher * SingleTagData * ManagedTCPMessageHub * PubsubDeserializationController * PublisherCore * InflaterHuffmanTree * AsyncTCPConnection_APM * ThreadSafeQueue * ManagedSubscriber * SubscriberCore * PubSubServerManagedTCPConnection * AsyncTCPConnection_APM * SuperMapStream * MapStream * TradeBarsStream	2024-07-09 15:14:26 -04:00

John Colvin	f92964114e	fix: Fix improper 'OfType' linq cast Previously, animations were expressed through polymorphism (derived from the base class CellAnimation), but the new impl uses composition. This 'OfType' call was leftover from the polymorphism implementation, an attempt to linq cast elements of base class (CellAnimation) to BackgroundAnimation.	2024-07-09 14:59:06 -04:00
John Colvin	baa0f1430b	editorconfig: Use standard c# capitalization rules * Use 'PascalCase' for public members (instead of 'snake_case') * Use 'camelCase' for private members (instead of '_snake_case')	2024-07-09 14:59:06 -04:00

John Colvin	eb0fcf0b84	refactor: Rename WebsocketServerConfig proto pkg 'bts.websocket_core' This matches the namespace used in spark_websocket csproj. Eventually, I'd like to use conventional capitalization (TitleCase namespaces/types, etc.), but let's shelf that until we have enough time/energy to do a more comprehensive refactoring.	2024-07-09 14:59:06 -04:00
