-# This file defines the global default configuration for docker deployments.
-# It is tracked in source control. For temporary modifications, please create
-# a separate file called ".env.local" (it's in .gitignore, so won't be tracked).
-# If a variable is defined in both files, the value in .env.local will be used.
-#
-# About the deployment procedure:
-#   We use Docker Compose to build images and launch containers for various services
-#   that make up our software suite:
-#     - sparkd
-#     - TODO: pubsub
-#     - TODO: md-publisher
-#     - TODO: webapp (DSQA on the web)
-#     - TODO: api-server (websocket based)
-#   From inside a devcontainer, you can launch all services in separate containers
-#   on your machine by running:
-#
-#     tools/deploy.sh
-#
-#   This script builds release versions for each service, packaged (generally) in
-#   self-contained directories. Next, it runs a few "docker compose" commands to
-#   build docker images loaded with the self-contained binaries from the previous
-#   step, and start containers with those images to run each service. To view the
-#   commands that deploy.sh runs internally (without actually running them), run:
-#
-#     tools/deploy.sh --dry-run
-#
-#   For additional information/help, run:
-#
-#     tools/deploy.sh --help

John Colvin	492ca0c28f	cleanup: Remove unused pubsub tag handler code * Removed 'IPubSubServerTagHandler.register' - All implementations of this function were empty * Removed 'IPubSubServerTagHandler.supportedTagTypes' - This property wasn't referenced anywhere * Remove IWorker inheritance from IPubSubServerTagHandler - No reason these interfaces have to be tied together	2024-07-10 13:35:18 -04:00

John Colvin	63b064ac79	Fix typo in log msg	2024-07-09 15:14:30 -04:00
John Colvin	b617775c29	Fix net7 -> net8 typo in publish_data_stream_web_app.py The DataStream Web App is on net8	2024-07-09 15:14:30 -04:00
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	3ba6a91ca7	vscode: Add DataStreamPublisher debug cfg to skip build	2024-07-09 15:14:30 -04:00
John Colvin	0abde9eb7c	build: Use separate cmd to build DataStreamSuite/QueryAnalyzer.sln The DataStreamSuite.sln builds the new webapp now, which will (eventually) replace DSQA. We'll keep it around for now, but with a clean separation from the main build.	2024-07-09 15:14:30 -04:00
John Colvin	1531a57bc5	feat: Add DataStream WebApp Included in DataStreamSuite.sln, but not DataStreamQueryAnalyzer.sln	2024-07-09 15:14:29 -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. When it is associated with a property via the JsonConverter attribute, dotnet json parsing code throws an exception if "T" isn't assignable to the property type.	2024-07-09 15:14:29 -04:00
John Colvin	f09d6badaf	fix build (api server): Change namespace to bts.websocket_core	2024-07-09 15:14:29 -04:00

John Colvin	5e2789d16e	Change externals url from ssh to https style So we don't need ssh keys to clone it (the builtin credential manager makes https authentication safe/easy)	2024-07-09 15:14:29 -04:00
John Colvin	9ebdb2e460	cleanup: Fix benign typos in build scripts Change BUILD_SPARK_PY var name to BUILD_PY (because these scripts to actually build 'spark')	2024-07-09 15:14:29 -04:00

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	089ba9b369	cleanup: Normalize indentation in TradeBarsStream	2024-07-09 15:09:02 -04:00

John Colvin	2506fb4f2b	cleanup: Remove empty file (clearly added by accident)	2024-07-09 14:59:06 -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	7104bd787a	refactor: Add WebsocketClient class Basically an ISubject (I/O) wrapper for IWebsocketConnectionGateway	2024-07-09 14:59:06 -04:00
John Colvin	5db92d1f7d	refactor: Change WebsocketServerConfig.port to uint32 It should always be a number between 1-65535	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
