# Git CLI Integration - Final Summary
|
||||
|
||||
## Problem Statement
|
||||
|
||||
Branch creation requires Git CLI integration (noted in API response). Semantic merging and SDG analysis per roadmap Phase 2+. Additional platform support (Bitbucket, etc.) can be added following the same pattern.
|
||||
|
||||
## Solution Delivered
|
||||
|
||||
### 1. Git CLI Integration ✅
|
||||
|
||||
**Implementation:**
|
||||
- Created `backend/include/wizardmerge/git/git_cli.h` - Git CLI wrapper API
|
||||
- Created `backend/src/git/git_cli.cpp` - Full implementation with 9 operations
|
||||
- Created `backend/tests/test_git_cli.cpp` - 9 comprehensive unit tests
|
||||
- Updated `backend/src/controllers/PRController.cc` - Branch creation workflow
|
||||
- Updated `backend/CMakeLists.txt` - Build system integration
|
||||
|
||||
**Features:**
|
||||
- `clone_repository()` - Clone repos with branch and depth options
|
||||
- `create_branch()` - Create and checkout branches
|
||||
- `checkout_branch()` - Switch branches
|
||||
- `add_files()` - Stage files for commit
|
||||
- `commit()` - Commit with config and message escaping
|
||||
- `push()` - Push to remote with upstream tracking
|
||||
- `get_current_branch()` - Query current branch
|
||||
- `branch_exists()` - Check branch existence
|
||||
- `status()` - Get repository status
|
||||
- `is_git_available()` - Verify Git availability
|
||||
|
||||
**API Enhancement:**
|
||||
- Removed "not yet implemented" note
|
||||
- Added `branch_created` field to response
|
||||
- Added `branch_name` field with auto-generated fallback
|
||||
- Added `branch_path` field pointing to local clone
|
||||
- Added `note` field with push instructions
|
||||
|
||||
**Security:**
|
||||
- Commit message escaping prevents injection
|
||||
- Git config validation with error handling
|
||||
- Proper shell quoting for file paths
|
||||
- No credentials embedded in URLs
|
||||
- Temp directories with unique timestamps
|
||||
|
||||
**Portability:**
|
||||
- Uses `std::filesystem::temp_directory_path()`
|
||||
- Includes `<sys/wait.h>` for WEXITSTATUS
|
||||
- Cross-platform compatible
|
||||
- No hardcoded `/tmp` paths
|
||||
|
||||
### 2. Semantic Merging Documentation ✅
|
||||
|
||||
**Added to ROADMAP.md Phase 2.1:**
|
||||
|
||||
**JSON Merging:**
|
||||
- Merge by key structure, preserve nested objects
|
||||
- Handle array conflicts intelligently
|
||||
- Detect structural vs. value changes
|
||||
- Smart array merging by ID fields
|
||||
|
||||
**YAML Merging:**
|
||||
- Preserve hierarchy and indentation
|
||||
- Maintain comments and anchors
|
||||
- Schema-aware conflict detection
|
||||
- Multi-document YAML support
|
||||
|
||||
**Package Files:**
|
||||
- `package.json` (npm): Merge by semver ranges
|
||||
- `requirements.txt` (pip): Detect version conflicts
|
||||
- `go.mod`, `Cargo.toml`, `pom.xml`: Language-specific resolution
|
||||
- Breaking version upgrade detection
|
||||
|
||||
**XML Merging:**
|
||||
- Preserve DTD and schema declarations
|
||||
- Match elements by attributes (e.g., `id`)
|
||||
- Handle namespaces correctly
|
||||
|
||||
**AST-Based Merging:**
|
||||
- **Python**: Imports, functions, classes, decorators, type hints
|
||||
- **JavaScript/TypeScript**: Modules, exports, React components
|
||||
- **Java**: Class structure, method overloads, annotations
|
||||
- **C/C++**: Header guards, includes, macros, namespaces
|
||||
|
||||
### 3. SDG Analysis Documentation ✅
|
||||
|
||||
**Added to ROADMAP.md Phase 2.1:**
|
||||
|
||||
**System Dependence Graph (SDG) Analysis:**
|
||||
Based on research paper achieving 28.85% reduction in conflict resolution time and suggestions for >70% of conflicted blocks.
|
||||
|
||||
**Implementation Approach:**
|
||||
- Build dependency graphs at multiple levels:
|
||||
- Text-level: Line and block dependencies
|
||||
- LLVM-IR level: Data and control flow (for C/C++)
|
||||
- AST-level: Semantic dependencies (all languages)
|
||||
- Use tree-sitter for AST parsing
|
||||
- Integrate LLVM for IR analysis
|
||||
- Build dependency database per file
|
||||
- Cache analysis results for performance
|
||||
|
||||
**Conflict Analysis:**
|
||||
- Detect true conflicts vs. false conflicts
|
||||
- Identify dependent code blocks
|
||||
- Compute conflict impact radius
|
||||
- Suggest resolution based on dependency chains
|
||||
- Visual dependency graph in UI
|
||||
- Highlight upstream/downstream dependencies
|
||||
|
||||
### 4. Platform Extensibility Documentation ✅
|
||||
|
||||
**Added to ROADMAP.md Phase 2.5:**
|
||||
|
||||
**Bitbucket Support:**
|
||||
- Bitbucket Cloud API integration
|
||||
- URL pattern: `https://bitbucket.org/workspace/repo/pull-requests/123`
|
||||
- Authentication via App passwords or OAuth
|
||||
- Support for Bitbucket Server (self-hosted)
|
||||
|
||||
**Azure DevOps Support:**
|
||||
- Azure DevOps REST API integration
|
||||
- URL pattern: `https://dev.azure.com/org/project/_git/repo/pullrequest/123`
|
||||
- Authentication via Personal Access Tokens
|
||||
- Support for on-premises Azure DevOps Server
|
||||
|
||||
**Gitea/Forgejo Support:**
|
||||
- Self-hosted Git service integration
|
||||
- Compatible API with GitHub/GitLab patterns
|
||||
- Community-driven platforms
|
||||
|
||||
**Extensible Platform Pattern:**
|
||||
|
||||
Interface design:
|
||||
```cpp
|
||||
class GitPlatformAPI {
|
||||
virtual PullRequest fetch_pr_info() = 0;
|
||||
virtual std::vector<std::string> fetch_file_content() = 0;
|
||||
virtual bool create_comment() = 0;
|
||||
virtual bool update_pr_status() = 0;
|
||||
};
|
||||
```
|
||||
|
||||
