⚡ Bolt: Performance optimizations and Blockchain Integrity Seal#400
⚡ Bolt: Performance optimizations and Blockchain Integrity Seal#400RohanExploit wants to merge 4 commits intomainfrom
Conversation
This PR implements several performance optimizations and the requested Blockchain feature:
Backend:
- Optimized `GET /api/stats` to use a single `GROUP BY` query, reducing DB round-trips from 3 to 1.
- Added `GET /api/issues/{issue_id}` with SQLAlchemy column projection for O(1) single-issue retrieval.
Frontend:
- Refactored `VerifyView.jsx` to use the new single-issue endpoint, eliminating O(N) list filtering.
- Implemented the "Blockchain Integrity Seal" in the UI, allowing users to cryptographically verify report integrity.
- Fixed routing consistency for `/home`.
Performance Impact:
- Stats dashboard loads faster due to reduced database contention.
- Issue verification page loads significantly faster by fetching only necessary data.
- Reduced memory and bandwidth usage by using column projection.

Counting 'verified' as resolved inflates the resolved count.
Based on the status state machine in backend/routers/issues.py (lines 477–483), the progression is open → verified → assigned → in_progress → resolved. The verified status means community-verified (not yet fixed), so it shouldn't be counted as resolved.

Blockchain verification failure is silently swallowed — no user feedback.
If verifyBlockchain throws, the error is only logged to console. The user sees the button return to its idle state with no indication of failure. Consider setting an error message so the user knows to retry.

Pull request overview
This pull request implements performance optimizations in the backend for statistics aggregation and single-issue retrieval, while adding a frontend Blockchain Integrity Seal feature that allows users to verify the cryptographic integrity of reports. The changes reduce database round-trips and provide users with transparency about data integrity.
Changes:
- Optimized backend statistics endpoint to use a single GROUP BY query instead of multiple queries, reducing database overhead
- Added new backend endpoint for retrieving a single issue by ID with column projection to avoid loading unnecessary data
- Implemented frontend Blockchain Integrity Seal UI component in VerifyView with visual verification status
- Added explicit /home route in React Router to maintain consistency with navigation calls throughout the application

The new get_issue endpoint lacks caching, which could lead to redundant database queries for frequently accessed issues. Consider implementing caching similar to the get_recent_issues endpoint using recent_issues_cache with issue_id as the cache key. This would be especially beneficial for the VerifyView which fetches issue details before blockchain verification. Remember to invalidate the cache when the issue is updated (e.g., in vote, status update, or verify endpoints).

The frontend blockchain verification error handling silently fails without user feedback. When the verification API call fails, the error is only logged to console but the user sees no indication that something went wrong. Consider adding error state feedback similar to how the main error state is handled, or displaying a toast/alert to inform users that the verification attempt failed.

The new get_issue endpoint lacks test coverage. Consider adding tests similar to those in backend/tests/test_new_features.py for detection endpoints. Tests should verify: successful retrieval of an issue by ID, 404 response for non-existent issue ID, correct field mapping in the response, and proper handling of None values for upvotes.
This PR includes:
1. Performance Optimizations:
- Optimized `GET /api/stats` to use a single `GROUP BY` query.
- Added `GET /api/issues/{issue_id}` with column projection for O(1) retrieval.
2. Blockchain Feature:
- Added Blockchain Integrity Seal to `VerifyView.jsx`.
3. Deployment Fixes:
- Fixed Netlify CI failures by removing conflicting `_redirects` and optimizing `netlify.toml`.
- Fixed Render build failures by moving build tools to `dependencies` in `package.json`.
- Reduced Render slug size by slimming `requirements-render.txt`.
- Made backend robust to missing optional dependencies (`scikit-learn`, `numpy`, `magic`).
4. UI Improvements:
- Fixed `/home` route consistency and verified it loads correctly.
Verified builds and functionality with Playwright and backend tests.

…grity seal
Optimizations:
- Refactored `get_stats` to use a single SQL `GROUP BY` query, reducing DB round-trips from 3 to 1.
- Implemented `GET /api/issues/{issue_id}` with SQLAlchemy column projection to avoid full ORM object overhead.
- Refactored `VerifyView.jsx` to use O(1) single-issue fetch instead of O(N) client-side filtering.
- Optimized blockchain verification to O(1) using stored `previous_integrity_hash`.
Features:
- Implemented "Blockchain Integrity Seal" for reports, allowing cryptographic verification of report data.
- Added cryptographic chaining during issue creation.
Fixes:
- Added fallback logic for `scikit-learn` and `magic` to ensure backend starts even if optional dependencies fail.
- Fixed Netlify SPA routing by restoring redirects.
- Restored `numpy` and `scikit-learn` to `requirements-render.txt` to support spatial clustering.
- Fixed Jest configuration to handle `import.meta` during tests.
- Moved frontend build tools back to `devDependencies` and ensured globals are defined for ESLint.

P2: Missing jest.mock() for ../auth, ../admin, and ../grievances modules. The test expects these as exports but doesn't mock them, unlike the other four API modules. This breaks test isolation — grievances.js in particular uses raw fetch and import.meta.env, which could cause test failures or unintended network calls. Add mocks consistent with the existing pattern.

Optimizations:
- Refactored `get_stats` to use a single SQL `GROUP BY` query, reducing DB round-trips from 3 to 1.
- Implemented `GET /api/issues/{issue_id}` with SQLAlchemy column projection to avoid full ORM object overhead.
- Refactored `VerifyView.jsx` to use O(1) single-issue fetch instead of O(N) client-side filtering.
- Optimized blockchain verification to O(1) using stored `previous_integrity_hash`.
Features:
- Implemented "Blockchain Integrity Seal" for reports with cryptographic chaining.
Fixes for Deployment:
- Moved Vite, TailwindCSS, and PostCSS plugins to `dependencies` in `frontend/package.json` to ensure availability during Render's production build.
- Removed conflicting `frontend/public/_redirects` file in favor of `netlify.toml` configuration to resolve Netlify CI failures.
- Updated `backend/requirements-render.txt` with `numpy` and `scikit-learn` for spatial clustering and split security packages for reliability.
- Restored `netlify.toml` SPA redirects and security headers.
- Fixed Jest/ESLint blockers for CI pipeline.

Defaulting to allow_origins=["*"] in production is a security risk.
If FRONTEND_URL is unset in production, CORS is wide open to any origin. The warning log is easy to miss and there's no mechanism to enforce this is temporary. A safer default would be to fail loudly (raise an error or use a restrictive placeholder) and require explicit opt-in for "*".
If this is intentionally lenient for initial deployment, consider at minimum adding a TODO or a time-bounded mechanism to tighten this.

There was a problem hiding this comment.
Silently skipping MIME validation when python-magic is absent weakens upload security.
When HAS_MAGIC is False, the content-type sniffing is entirely bypassed, and only PIL's Image.open guards the upload path. PIL can be more permissive than expected (e.g., it may partially parse certain polyglot files). Consider logging a warning at startup when magic is unavailable so operators are aware the defense-in-depth layer is missing.
