Core abstractions live in `ManagedCode.Storage.Core/`. Providers sit under `Storages/ManagedCode.Storage.*` with one project per cloud target (Azure, AWS, GCP, FileSystem, Sftp). Integration surfaces, including the ASP.NET server and client SDKs, live in `Integraions/`. Test doubles stay in `ManagedCode.Storage.TestFakes/`, while the suites in `Tests/ManagedCode.Storage.Tests/` are grouped into ASP.NET flows, provider runs, and shared helpers. Keep shared assets such as `logo.png` at the repository root. + +## Build, Test, and Development Commands +Run `dotnet restore ManagedCode.Storage.slnx` before compiling. Use `dotnet build ManagedCode.Storage.slnx` to compile every target and surface analyzer warnings. Execute all tests with `dotnet test Tests/ManagedCode.Storage.Tests/ManagedCode.Storage.Tests.csproj --configuration Release`. For coverage, run `dotnet test /p:CollectCoverage=true /p:CoverletOutput=coverage /p:CoverletOutputFormat=opencover`. Use `dotnet format ManagedCode.Storage.slnx` before opening a pull request. + +## Coding Style & Naming Conventions +Follow standard C# conventions: 4-space indentation, PascalCase types, camelCase locals, and suffix async APIs with `Async`. Nullability is enabled repository-wide, so annotate optional members and avoid the suppression operator unless justified. Match method names to existing patterns such as `DownloadFile_WhenFileExists_ReturnsSuccess`. Remove unused usings and let analyzers guide layout. + +## Testing Guidelines +Tests use xUnit and Shouldly; choose `[Fact]` for atomic cases and `[Theory]` for data-driven permutations. Place provider suites under `Tests/ManagedCode.Storage.Tests/Storages/` and reuse `.../Common/` helpers to spin up Testcontainers (Azurite, LocalStack, FakeGcsServer). Add fakes or harnesses mirroring `ManagedCode.Storage.TestFakes/` when introducing new providers. Always run `dotnet test` locally and exercise critical upload/download paths. + +## Commit & Pull Request Guidelines +Write commit subjects in the imperative mood (`add ftp retry policy`) and keep them provider-scoped. Group related edits in one commit and avoid WIP spam. Pull requests should summarize impact, list touched projects, reference issues, and note new configuration or secrets. Include the `dotnet` commands you ran and add logs when CI needs context. + +## Security & Configuration Tips +Never commit API keys, connection strings, or `.trx` artifacts; rely on environment variables or user secrets. Document minimal permissions and default container expectations for new providers. Ensure server integrations stay authenticated and refresh configuration examples in `README.md` when behavior changes. diff --git a/CLAUDE.md b/CLAUDE.md new file mode 100644 index 00000000..20790015 --- /dev/null +++ b/CLAUDE.md @@ -0,0 +1,88 @@ +# CLAUDE.md + +This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository. + +## Build and Development Commands + +### Basic Commands +- **Build**: `dotnet build` - Builds the entire solution +- **Restore**: `dotnet restore` - Restores NuGet packages +- **Test**: `dotnet test` - Runs all tests +- **Test with Coverage**: `dotnet test /p:CollectCoverage=true /p:CoverletOutput=coverage /p:CoverletOutputFormat=opencover` + +### Testing Specific Projects +- **Run single test project**: `dotnet test Tests/ManagedCode.Storage.Tests/ManagedCode.Storage.Tests.csproj` +- **Run specific test**: `dotnet test --filter "ClassName.MethodName"` + +### Project Structure +This is a .NET 9 solution targeting multiple cloud storage providers with a universal interface. + +## Architecture Overview + +### Core Architecture +The solution follows a provider pattern with: + +- **Core Library** (`ManagedCode.Storage.Core`): Base interfaces and abstract classes + - `IStorage`: Generic storage interface with client and options + - `BaseStorage`: Abstract base implementation + - Common models: `BlobMetadata`, `UploadOptions`, `DownloadOptions`, etc. + +- **Storage Providers** (in `Storages/` directory): + - `ManagedCode.Storage.Azure`: Azure Blob Storage + - `ManagedCode.Storage.Azure.DataLake`: Azure Data Lake Storage + - `ManagedCode.Storage.Aws`: Amazon S3 + - `ManagedCode.Storage.Google`: Google Cloud Storage + - `ManagedCode.Storage.FileSystem`: Local file system + +- **Integrations** (in `Integraions/` directory): + - `ManagedCode.Storage.Server`: ASP.NET Core extensions + - `ManagedCode.Storage.Client`: Client SDK + - `ManagedCode.Storage.Client.SignalR`: SignalR integration + +### Key Interfaces +- `IStorage`: Main storage interface combining uploader, downloader, streamer, and operations +- `IUploader`: File upload operations +- `IDownloader`: File download operations +- `IStreamer`: Stream-based operations +- `IStorageOperations`: Blob metadata and existence operations + +### Connection Modes +The library supports two connection modes: +1. **Default mode**: Use `IStorage` interface (single provider) +2. **Provider-specific mode**: Use provider-specific interfaces like `IAzureStorage`, `IAWSStorage` + +### Provider Factory Pattern +- `IStorageFactory`: Creates storage instances +- `IStorageProvider`: Provider registration interface +- Extension methods for DI registration (e.g., `AddAzureStorage`, `AddAWSStorageAsDefault`) + +## Testing +- Uses xUnit with Shouldly +- Testcontainers for integration testing (Azurite, LocalStack, FakeGcsServer) +- Test projects follow pattern: `Tests/ManagedCode.Storage.Tests/` +- Includes test fakes in `ManagedCode.Storage.TestFakes` + +## Development Patterns +- All providers inherit from `BaseStorage` +- Options classes implement `IStorageOptions` +- Result pattern using `ManagedCode.Communication.Result` +- Async/await throughout with CancellationToken support +- Dependency injection via extension methods + +## Common Operations +```csharp +// Upload +await storage.UploadAsync(stream, options => { + options.FileName = "file.txt"; + options.MimeType = "text/plain"; +}); + +// Download +var file = await storage.DownloadAsync("file.txt"); + +// Delete +await storage.DeleteAsync("file.txt"); + +// Check existence +var exists = await storage.ExistsAsync("file.txt"); +``` \ No newline at end of file diff --git a/Directory.Build.props b/Directory.Build.props index 8b5a5047..3a60b820 100644 --- a/Directory.Build.props +++ b/Directory.Build.props @@ -6,6 +6,7 @@ true embedded enable + true diff --git a/Integraions/ManagedCode.Storage.Client.SignalR/Class1.cs b/Integraions/ManagedCode.Storage.Client.SignalR/Class1.cs deleted file mode 100644 index 39ce40c0..00000000 --- a/Integraions/ManagedCode.Storage.Client.SignalR/Class1.cs +++ /dev/null @@ -1,5 +0,0 @@ -namespace ManagedCode.Storage.Client.SignalR; - -public class Class1 -{ -} \ No newline at end of file diff --git a/Integraions/ManagedCode.Storage.Client.SignalR/IStorageSignalRClient.cs b/Integraions/ManagedCode.Storage.Client.SignalR/IStorageSignalRClient.cs new file mode 100644 index 00000000..00846f2c --- /dev/null +++ b/Integraions/ManagedCode.Storage.Client.SignalR/IStorageSignalRClient.cs @@ -0,0 +1,92 @@ +using System; +using System.Collections.Generic; +using System.IO; +using System.Threading; +using System.Threading.Tasks; +using ManagedCode.Storage.Client.SignalR.Models; + +namespace ManagedCode.Storage.Client.SignalR; + +/// +/// Defines the contract for interacting with the storage SignalR hub. +/// +public interface IStorageSignalRClient : IAsyncDisposable +{ + /// + /// Occurs when the hub reports transfer progress. + /// + event EventHandler?
