  • RUN_ONCE=true runs the parser-file check once after Discord Ready then exits - used by the daily ECS Fargate scheduled task (replaces the 24/7 service); a 2-minute ready timeout prevents hung tasks on auth failure
  • waits for gateway Ready before checking (the old code raced StartAsync) and uses minimal gateway intents in run-once mode
  • Discord upload cap now uses channel.Guild.MaxUploadLimit instead of the 2021-era hardcoded 8 MB
  • dockerfile rebuilt as multi-stage net10.0 from source (was copying a prebuilt net7.0 folder)
  • all NuGet packages bumped to latest (Discord.Net 3.20.1, AWSSDK.S3 4.0.102.1, ParserInputGenerator 4.1.0, Shared 6.0.0, Microsoft.* 10.0.11, MSTest 4.3.3)

Summary by CodeRabbit

  • New Features

    • Added a run-once mode for downloading and uploading files before automatic shutdown.
    • Startup now waits for the Discord connection to become ready, with timeout and cancellation support.
    • Archive size limits now follow the configured Discord upload limit.
  • Chores

    • Updated the application to build and run with .NET 10.
    • Refreshed application and test package versions.
    • Added Docker ignore rules for generated and temporary files.

- RUN_ONCE=true runs the parser-file check once after Discord Ready then exits (for daily ECS scheduled task); 2-min ready timeout prevents hung tasks
- wait for gateway Ready before the check instead of racing StartAsync
- minimal gateway intents in run-once mode (no privileged intents required)
- use channel.Guild.MaxUploadLimit instead of hardcoded 8MB Discord cap
- multi-stage net10.0 dockerfile building from source (was stale prebuilt net7.0)
- bump all NuGet packages to latest (Discord.Net 3.20.1, AWSSDK.S3 4.0.102.1, NosCore.ParserInputGenerator 4.1.0, NosCore.Shared 6.0.0, MS.* 10.0.11, MSTest 4.3.3)

Review Change Stack

Walkthrough

The project updates package versions, adds RUN_ONCE execution with graceful shutdown, uses guild upload limits, and changes the Docker image to a .NET 10 multi-stage build.

Changes

Runtime and delivery

Layer / File(s) Summary
Project dependency updates
src/NosCoreBot/NosCoreBot.csproj, tests/NosCoreBot.Tests/NosCoreBot.Tests.csproj
The application and test projects reference newer package versions.
One-time Discord execution
src/NosCoreBot/Program.cs, src/NosCoreBot/Worker.cs, src/NosCoreBot/Services/TimeHandlingService.cs
RUN_ONCE limits Discord intents, waits for readiness, uploads files, stops the client, and requests application shutdown. Upload validation uses the guild upload limit.
Container build and runtime
.dockerignore, src/NosCoreBot/dockerfile
The Dockerfile uses .NET 10 SDK and ASP.NET stages. It publishes Release output and excludes build artifacts from the build context.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to c2d08

The Docker build uses mutable .NET 10 image tags and may use a larger ASP.NET runtime image than necessary for this executable, which can reduce build reproducibility and increase image size without indicating a correctness or availability failure; the PR is mergeable with explicit owner follow-up.

Use runtime:10.0 when ASP.NET Core is not required.

src/NosCoreBot/NosCoreBot.csproj at Lines 1-6 declares <OutputType>Exe</OutputType>, and the PR describes a Discord bot. If the project does not reference Microsoft.AspNetCore.App, replace the ASP.NET image with the smaller .NET runtime image.

Pin the base images to immutable references.

The 10.0 tags are mutable. The CI command in .github/workflows/dotnet.yml at Lines 45-46 uses --no-cache, so a fresh build can resolve different SDK and runtime layers without a source change. Pin both FROM instructions to reviewed digests and update those digests through a controlled dependency process.
