feat(tags): Add database schema and tags module (v1.3.0 Phase 1)
Implements tag/category system backend following microformats2 p-category specification. Database changes: - Migration 008: Add tags and note_tags tables - Normalized tag storage (case-insensitive lookup, display name preserved) - Indexes for performance New module: - starpunk/tags.py: Tag management functions - normalize_tag: Normalize tag strings - get_or_create_tag: Get or create tag records - add_tags_to_note: Associate tags with notes (replaces existing) - get_note_tags: Retrieve note tags (alphabetically ordered) - get_tag_by_name: Lookup tag by normalized name - get_notes_by_tag: Get all notes with specific tag - parse_tag_input: Parse comma-separated tag input Model updates: - Note.tags property (lazy-loaded, prefer pre-loading in routes) - Note.to_dict() add include_tags parameter CRUD updates: - create_note() accepts tags parameter - update_note() accepts tags parameter (None = no change, [] = remove all) Micropub integration: - Pass tags to create_note() (tags already extracted by extract_tags()) - Return tags in q=source response Per design doc: docs/design/v1.3.0/microformats-tags-design.md Generated with Claude Code Co-Authored-By: Claude <noreply@anthropic.com>

# v1.2.0 Phase 3 Architecture Review: Media Upload
|
||||
|
||||
**Date**: 2025-11-28
|
||||
**Reviewer**: StarPunk Architect Subagent
|
||||
**Phase**: v1.2.0 Phase 3 - Media Upload
|
||||
**Developer**: StarPunk Developer Subagent
|
||||
**Status**: REVIEWED
|
||||
|
||||
## Executive Summary
|
||||
|
||||
The Phase 3 media upload implementation has been thoroughly reviewed against the architectural specifications, ADRs, and Q&A decisions. The implementation demonstrates excellent adherence to design principles and successfully delivers the social media-style attachment model as specified.
|
||||
|
||||
## ✅ What Went Well
|
||||
|
||||
### 1. **Design Adherence**
|
||||
- Perfect implementation of ADR-057 social media attachment model
|
||||
- Media displays at TOP of notes exactly as specified
|
||||
- Text content properly positioned BELOW media
|
||||
- Clean separation between media and content
|
||||
|
||||
### 2. **Technical Implementation**
|
||||
- Excellent use of Pillow for image validation and optimization
|
||||
- UUID-based filename generation prevents collisions effectively
|
||||
- Date-organized storage structure (`data/media/YYYY/MM/`) implemented correctly
|
||||
- Proper EXIF orientation handling
|
||||
- Security measures well-implemented (path traversal prevention, MIME validation)
|
||||
|
||||
### 3. **Database Design**
|
||||
- Junction table approach provides excellent flexibility
|
||||
- Foreign key constraints and cascade deletes properly configured
|
||||
- Indexes appropriately placed for query performance
|
||||
- Caption support integrated seamlessly
|
||||
|
||||
### 4. **Feed Integration**
|
||||
- RSS: HTML embedding in CDATA blocks works perfectly
|
||||
- ATOM: Dual approach (enclosures + HTML) maximizes compatibility
|
||||
- JSON Feed: Native attachments array cleanly implemented
|
||||
- Absolute URLs correctly generated across all feed formats
|
||||
|
||||
### 5. **Error Handling**
|
||||
- Graceful handling of invalid images
|
||||
- Clear error messages for users
|
||||
- Non-atomic upload behavior (per Q35) allows partial success
|
||||
|
||||
### 6. **Test Coverage**
|
||||
- Comprehensive test suite using PIL-generated images (no binary files)
|
||||
- All edge cases covered: file size, dimensions, format validation
|
||||
- Multiple image attachment scenarios tested
|
||||
- Caption handling verified
|
||||
|
||||
### 7. **Performance Optimizations**
|
||||
- Immutable cache headers (1 year) for served media
|
||||
- Efficient image resizing strategy (2048px threshold)
|
||||
- Lazy loading potential with width/height stored
|
||||
|
||||
## ⚠️ Issues Found
|
||||
|
||||
### Minor Issues (Non-blocking)
|
||||
|
||||
1. **GIF Animation Handling**
|
||||
- Line 119 in `media.py`: Animated GIFs are returned unoptimized
|
||||
- This is acceptable for v1.2.0 but should be documented as a known limitation
|
||||
- Recommendation: Add comment explaining why animated GIFs skip optimization
|
||||
|
||||
2. **Missing Input Validation in Route**
|
||||
- `admin.py` lines 114-128: No check for empty file uploads before processing
|
||||
- While handled by `save_media()`, earlier validation would be cleaner
|
||||
- Recommendation: Skip empty filename entries before calling save_media
|
||||
|
||||
3. **Preview JavaScript Accessibility**
|
||||
- `new.html` lines 139-140: Preview images lack proper alt text
|
||||
- Should use filename or "Preview" + index for better accessibility
|
||||
- Recommendation: Update JavaScript to include meaningful alt text
|
||||
|
||||
### Observations (No Action Required)
|
||||
|
||||
1. **No Thumbnail Generation**: As per design, relying on CSS for responsive sizing
|
||||
2. **No Drag-and-Drop Reordering**: Display order = upload order, as specified
|
||||
3. **No Micropub Media Endpoint**: Correctly scoped out for v1.2.0
|
||||
|
||||
