-# 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	322152c743	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".	2024-06-26 14:33:04 -04:00
John Colvin	9ab39587e2	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.	2024-06-26 14:33:04 -04:00

John Colvin	18662fcc0d	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)	2024-06-26 14:33:04 -04:00
John Colvin	16ffc48846	cleanup: Fix benign typos in build scripts Change BUILD_SPARK_PY var name to BUILD_PY (because these scripts to actually build 'spark')	2024-06-26 14:33:04 -04:00

John Colvin	3e401a766d	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	2024-06-26 14:33:03 -04:00

John Colvin	c1f8aadd5d	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.	2024-06-26 14:33:03 -04:00
John Colvin	ad5e0c77fe	editorconfig: Use standard c# capitalization rules * Use 'PascalCase' for public members (instead of 'snake_case') * Use 'camelCase' for private members (instead of '_snake_case')	2024-06-26 14:33:03 -04:00

John Colvin	6dd701dd33	refactor: Change WebsocketServerConfig.port to uint32 It should always be a number between 1-65535	2024-06-26 14:33:03 -04:00
John Colvin	456c953839	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.	2024-06-26 14:33:03 -04:00
