feat: Windows Adapter, Interactive TUI, and Smart Socket Analysis by codewithwan · Pull Request #2 · rewrite-everything-in-rust/witr-rs

codewithwan · 2025-12-30T14:40:30Z

Summary

This PR significantly expands witr-rs capabilities by introducing a robust Windows adapter, an interactive Terminal UI (TUI), and "Smart Socket Analysis" for detailed network diagnostics. It also solidifies the project's stability with a comprehensive, cross-platform CI/CD pipeline supporting Windows, Linux (including Arch/Fedora), and macOS (Intel & Apple Silicon).

Key Features

Windows Adapter Support: Full implementation of process inspection, service detection, and network analysis using native Windows commands (netstat, tasklist).
Interactive TUI:
- New Tree View for visualizing process ancestry.
- Watch Mode for real-time process monitoring.
- Optimized Global Mode for system overview.
Smart Socket Analysis:
- Enriched SocketInfo model providing human-readable Explanations and Workarounds for socket states (e.g., TIME_WAIT).
- Full IPv6 support and detailed state parsing.

Technical Enhancements

Cross-Platform CI/CD:
- Added GitHub Actions for automated testing on Windows, Ubuntu, and macOS (explicit support for Apple Silicon/M1).
- Implemented Linux Distro Matrix (Arch Linux, Fedora) validation via Docker containers.
- Automated release binary generation for x86_64 and aarch64.
Architecture Refactor: Standardized SocketInfo return types across Windows, Linux, and macOS adapters to ensure consistent core logic execution

Quality Assurance

Passed cargo clippy (linting) and cargo fmt.
Unit tests added for socket state logic, key generation, and network parsing.
Validated runtime behavior on Windows (netstat -ano parsing).

        sys.refresh_all();

+        Self {
+            sys: RefCell::new(sys),


Using RefCell to wrap the entire System object introduces runtime borrow checking overhead and potential panic risks if multiple borrows occur. While this enables interior mutability for the refresh operations, it's error-prone. Consider refactoring the SystemProvider trait to allow mutable methods, or use RefCell more selectively only for the fields that need mutation. Also, ensure all borrows are properly scoped to avoid holding references longer than necessary.

-    pub fn get_socket_state(_pid: u32) -> HashMap<u64, String> {
+    pub fn get_socket_state(_pid: u32) -> HashMap<u64, SocketInfo> {


The socket state parsing returns HashMap<u64, SocketInfo> but the old implementation returned HashMap<u64, String>. This is a breaking API change. While the PR description mentions "Architecture Refactor", ensure that all consumers of this API are updated accordingly. The stub implementation at the end of the file has been updated correctly, which is good.

The test data was updated to show "127.0.0.1:5432->1.1.1.1:80" but the comment on line 25 states "NAME field format: 127.0.0.1:5432->127.0.0.1:5433 (ESTABLISHED)". This inconsistency between the comment and test data could cause confusion. Update the comment to match the test data or vice versa.

The removal of the header lines for the security report might make the output less clear when security scanning is performed. The removed lines provided clear visual separation and identification of the report type. Consider whether this removal was intentional, and if so, ensure the calling code or context provides adequate framing for the security report output.

The README.md has a line marker "0 |----" at line 179 which appears to be a diff artifact or formatting error. This should be removed as it's not valid markdown content and will render incorrectly.

+        app.title = " Witr-RS Global Monitor (Detail Fetch Disabled - CPU Optimized) ".to_string();


The message "Detail Fetch Disabled - CPU Optimized" uses inconsistent terminology. The comment on line 89 says "resource intensive" and "optimize performance later", but the user-facing message says "CPU Optimized" which implies it's a feature rather than a limitation. Consider making the message more transparent, such as "Global Monitor (Optimization in Progress)" or "Global Monitor - Process Details Coming Soon".

The test data shows a local address of "0100007F:1F90" in the old code which was changed to "00000000:1F90" (representing 0.0.0.0:8080 instead of 127.0.0.1:8080). This changes the test's semantic meaning - LISTEN on 0.0.0.0 means listening on all interfaces, while 127.0.0.1 means localhost only. Ensure this change is intentional and doesn't mask a parsing issue.

+            assert_eq!(s.port, 631); // 0277 hex -> 631
+        }


The test comment states "0277 hex -> 631" but should verify the calculation is correct. 0x0277 = 2256 + 716 + 7 = 631 decimal. This is correct. However, the assertion only checks the state and port, but doesn't verify the local_addr format which the new implementation now provides. Consider adding assertions for local_addr and remote_addr to ensure the parsing is complete.

The error messages use inconsistent quoting styles. Line 75 says "Global Watch Mode is currently disabled/WIP" without quotes around the mode name, while line 79 uses escaped quotes in "witr-rs --watch". Consider using consistent formatting for better readability, such as using backticks or quotes consistently for command-line arguments and mode names.

The CI workflow is configured to use "macos-14" which is an Apple Silicon (M1) runner, but the comment on line 111 says "Intel build on M1 runner". This is contradictory - macOS-14 runners are Apple Silicon (ARM64) by default, not Intel. If you want to build for x86_64 on an Apple Silicon runner, you need to ensure proper cross-compilation setup. Verify that building x86_64-apple-darwin on macos-14 works correctly, or consider using macos-13 for Intel builds.

Suggested change

- os: macos-14 # x86_64 (Intel-compatible) build on Apple Silicon runner
