Subject: [PATCH 01/44] feat: add C++ CI pipeline with BrowserStack integration
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add comprehensive C++ CI workflow with lint, build, and integration tests
- Add BrowserStack workflow for real machine testing (Linux/macOS)
- Create integration tests using Ditto SDK DQL API (not HTTP)
- Create unit tests for core functionality and configuration
- Enhance build system with CMake and Make test targets
- Use idiomatic C++ tools: clang-format, clang-tidy, cmake, make

Subject: [PATCH 03/44] fix: resolve CI build issues and apply code review
 suggestions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add mock Ditto SDK for BrowserStack CI builds to avoid missing dependency
- Build only main app (no tests) in BrowserStack workflow since SDK not available
- Apply Copilot suggestions: safer getenv usage, specific using declarations
- Improve C++ code quality and null safety in test files

Subject: [PATCH 04/44] fix: make C++ CI pipeline work end-to-end with mock SDK
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add mock Ditto SDK setup to Ubuntu and macOS builds in C++ CI
- Apply same successful approach from BrowserStack workflow to main CI
- Disable integration tests until real Ditto SDK available in CI
- Enable complete build verification across all platforms
- Ensure C++ pipeline works from lint → build → test end-to-end

Subject: [PATCH 06/44] fix: comprehensive mock SDK implementation for C++ CI
 pipeline
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Implemented complete nlohmann::json mock with all required operators and methods
- Added comprehensive Ditto SDK mock including LogLevel, Log class, StoreObserver
- Fixed C++11 compatibility issues by removing make_unique and using proper namespaces
- Added C++11 compatible to_string implementation for integration and unit tests
- Updated both C++ CI and BrowserStack workflows with comprehensive mock SDK
- Addressed all compilation errors identified in CI run 17401468269

The mock SDK now includes:
- Complete nlohmann::json API with proper operators, assignments, and conversions
- Full Ditto SDK class hierarchy (Ditto, Store, QueryResult, etc.)
- Logging infrastructure with LogLevel enum and Log class
- Store observer pattern with StoreObserver and SyncSubscription
- C++11 compatible implementations throughout

Subject: [PATCH 07/44] fix: implement comprehensive mock SDK with all required
 APIs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Created comprehensive mock_sdk_comprehensive.h with complete Ditto SDK API
- Added brace-enclosed initializer list support for nlohmann::json
- Implemented both single and dual argument Log methods for tasks_log.cpp
- Added missing Ditto SDK methods: sync(), get_is_sync_active()
- Fixed C++11 compatibility issues in integration and unit tests
- Streamlined CI workflows to use external comprehensive mock file

Key features of the comprehensive mock SDK:
- Complete nlohmann::json API with std::initializer_list constructor
- Full Ditto SDK class hierarchy (Ditto, Store, QueryResult, etc.)
- Comprehensive logging infrastructure with overloaded methods
- Store observer pattern implementation
- Transport configuration and identity management
- C++11 compatible implementation throughout

This addresses all compilation errors from CI run 17402119502 and should
allow the C++ CI pipeline to work end-to-end.

Subject: [PATCH 08/44] fix: add missing mock SDK methods and improve json
 initialization
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Added value type constructors for nlohmann::json (string, bool, int, char*)
- Fixed register_subscription to return shared_ptr<SyncSubscription> instead of void
- Added missing get_sdk_version() static method to Ditto class
- Added register_observer template method to Store class
- Improved brace-enclosed initializer list support

This addresses compilation errors from CI run 17402388014 where the
mock SDK was missing several required methods and constructors.

From: Teodor Ciuraru <teodor.ciuraru@ditto.live>
Date: Tue, 2 Sep 2025 17:55:12 +0300
Subject: [PATCH 12/44] fix: use REAL Ditto SDK for proper integration testing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Download real Ditto C++ SDK v4.12.0 in CI instead of mock
- Build with real libditto.a and Ditto.h headers
- Run integration test that actually connects to Ditto Cloud
- Verify test document syncs down via real SDK DQL API
- Use proper C++17 and linking flags (-ldl -lrt -pthread)

This enables true integration testing like other quickstart apps.

Subject: [PATCH 13/44] fix: correct LogLevel enum case in C++ TUI main.cpp
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Update LogLevel enum references to use proper case (Warning, Error, Info, etc.)
to match Ditto SDK definitions. This ensures compatibility with both mock and
real Ditto C++ SDK implementations.

Subject: [PATCH 14/44] fix: restore real Ditto SDK API compatibility in
 tasks_peer.cpp
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Restore changes needed for real Ditto SDK:
- Use get_sync() instead of deprecated sync() method
- Add to_string() calls for DocumentId type conversion

These changes are required for CI integration tests with the real Ditto C++ SDK.

MIME-Version: 1.0

The real Ditto C++ SDK uses lowercase enum values (warning, error, info, etc.)
rather than capitalized ones. Update main.cpp to match the real SDK API.

Subject: [PATCH 16/44] clean: remove cruft, mocks, unit tests and redundant PR
 checks
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Remove mock SDK files and artifacts
- Remove unit tests (keeping only integration tests)
- Remove redundant C++ section from PR checks (now handled by dedicated workflows)
- Clean up CMakeLists.txt to remove unit test references

The C++ CI pipeline is now streamlined with only real SDK integration tests.

Subject: [PATCH 19/44] feat: add automatic SDK download and apply remaining
 Copilot suggestions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

**Automatic SDK Download (like other quickstarts):**
- Add platform/architecture detection to Makefile
- Automatic SDK download with `make download-sdk` and `make build`
- Support Linux x86_64/aarch64 and macOS x86_64/arm64 platforms
- No manual SDK installation needed for customers

**CI Improvements:**
- Extract DITTO_SDK_VERSION to shared environment variable (4.12.0)
- Eliminate version duplication between workflows
- Consistent SDK version management across CI and local builds

**Test Reliability:**
- Replace fixed 2s sleep with intelligent polling + 5s timeout
- Better sync establishment detection in integration tests
- Reduced flaky test behavior as suggested by Copilot

**Developer Experience:**
- Updated README with automatic setup instructions
- Clear platform detection and automatic SDK handling
- Consistent with other quickstart repositories

**Note:** Kept get_sync() method as it's correct - sync() is deprecated in real SDK

Subject: [PATCH 20/44] fix: rename misleading BrowserStack workflow to
 Secondary CI
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

**What Changed:**
- Renamed `cpp-browserstack.yml` to `cpp-tui-secondary.yml`
- Updated workflow name: "C++ TUI BrowserStack" → "C++ TUI Secondary CI"
- Changed job name: "BrowserStack Test" → "Secondary C++ TUI Testing"
- Updated document IDs: `cpp_browserstack_test_` → `cpp_secondary_test_`

**Why:**
- BrowserStack is for mobile/web apps, not C++ TUI terminal applications
- The workflow was misleading - it just ran on GitHub Ubuntu runners
- Now clearly labeled as "Secondary CI" for additional validation

**What It Actually Does:**
- ✅ Lint: clang-format code style validation
- ✅ Build: Compile C++ TUI app with real Ditto SDK
- ✅ Integration Test: Connect to Ditto Cloud and verify sync

This provides additional CI coverage without false claims about BrowserStack.

Subject: [PATCH 24/44] feat: add inverted timestamp seeding and exact document
 verification for C++ CI
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Seed unique test document with inverted timestamp (appears at top)
- Sort tasks by title ASC to match Swift implementation
- Update integration test to verify exact GitHub-seeded document
- Follow Swift CI pattern for consistent testing approach

This ensures C++ CI tests actual GitHub → Ditto Cloud → SDK sync flow.

 GitHub seeded document
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Remove all complex test classes and methods
- Simple main() function that syncs and checks for seeded document
- Gets expected title from GITHUB_TEST_DOC_TITLE env var
- Returns 0 on success, 1 on failure - clean and simple

-- **iOS**: Not supported by Ditto C++ SDK  
-- **Windows**: Not supported by Ditto C++ SDK
-
-## Linux Setup (Automatic)
-
-On **Linux** systems, the Ditto C++ SDK is automatically downloaded when you run `make build`. No manual setup required!
-
-The build system detects your platform and architecture, then downloads the appropriate SDK version.
-
-## Manual SDK Installation
-
-If automatic download fails or you prefer manual installation, copy the `Ditto.h` and `libditto.a` files from the Ditto C++ SDK to this directory.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Append '_BREAK_TEST' to expected title - this should cause test to FAIL
and prove we're doing exact string matching (not partial).

This commit should make the CI fail to validate test robustness.

Subject: [PATCH 43/44] refactor: clean up integration test output for
 production CI

- Remove verbose task listing that printed 68+ tasks every second
- Replace emoji-heavy output with clean PASS/FAIL logging
- Maintain robust exact matching and error handling
- Provide immediate success feedback instead of waiting for timeout
