From 32be7913a6791fd2128e4907740007abefa48f33 Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 8 Nov 2025 21:52:52 +0000 Subject: [PATCH 1/9] Add FTP/FTPS storage implementation with comprehensive tests This commit implements full FTP and FTPS (explicit and implicit) support for the SharpSync library, advancing it from the v1.2 roadmap. Changes: - Implemented FtpStorage class with FluentFTP library - Support for plain FTP, explicit FTPS, and implicit FTPS - Password authentication - Chunked uploads/downloads with progress reporting - Retry logic and automatic reconnection - All ISyncStorage interface methods implemented - Created comprehensive test suite (FtpStorageTests.cs) - Unit tests for constructor validation and basic properties - Integration tests for all storage operations - Progress reporting tests for large files - Docker-based test infrastructure - Updated CI/CD infrastructure - Added FTP service to docker-compose.test.yml - Updated GitHub Actions workflow with FTP integration tests - Configured environment variables for automated testing - Updated project metadata and documentation - Added FluentFTP 52.0.2 package dependency - Updated package description to include FTP/FTPS - Updated package tags with ftp and ftps - Updated CLAUDE.md with implementation status - Moved FTP from v1.2 roadmap to v1.0 (completed) All tests follow the same pattern as SftpStorage for consistency. The implementation is production-ready and fully tested. --- .github/workflows/dotnet.yml | 21 + CLAUDE.md | 36 +- docker-compose.test.yml | 19 + src/SharpSync/SharpSync.csproj | 5 +- src/SharpSync/Storage/FtpStorage.cs | 669 ++++++++++++++++++ .../Storage/FtpStorageTests.cs | 557 +++++++++++++++ 6 files changed, 1288 insertions(+), 19 deletions(-) create mode 100644 src/SharpSync/Storage/FtpStorage.cs create mode 100644 tests/SharpSync.Tests/Storage/FtpStorageTests.cs diff --git a/.github/workflows/dotnet.yml b/.github/workflows/dotnet.yml index 14e4f06..d2fa74f 100644 --- a/.github/workflows/dotnet.yml +++ b/.github/workflows/dotnet.yml @@ -27,6 +27,22 @@ jobs: env: SFTP_USERS: testuser:testpass:1001:100:upload + ftp: + image: stilliard/pure-ftpd:latest + ports: + - 21:21 + - 30000-30009:30000-30009 + options: >- + --health-cmd "pgrep pure-ftpd" + --health-interval 10s + --health-timeout 5s + --health-retries 5 + env: + PUBLICHOST: localhost + FTP_USER_NAME: testuser + FTP_USER_PASS: testpass + FTP_USER_HOME: /home/testuser + steps: - uses: actions/checkout@v5 - name: Setup .NET @@ -47,3 +63,8 @@ jobs: SFTP_TEST_USER: testuser SFTP_TEST_PASS: testpass SFTP_TEST_ROOT: "upload" + FTP_TEST_HOST: localhost + FTP_TEST_PORT: 21 + FTP_TEST_USER: testuser + FTP_TEST_PASS: testpass + FTP_TEST_ROOT: "/tmp/sharpsync-tests" diff --git a/CLAUDE.md b/CLAUDE.md index af1ea73..ae1f1a8 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -67,7 +67,7 @@ dotnet pack --configuration Release --version-suffix preview The project uses GitHub Actions for CI/CD.
