* feat: Enhanced BLOB support across all database backends
- Add comprehensive BLOB support for all supported databases:
* PostgreSQL: BYTEA columns with data URL conversion
* MySQL/MariaDB: BLOB columns with data URL conversion
* MSSQL: VARBINARY, BIGVARBINARY, BINARY, IMAGE columns
* SQLite: BLOB columns with data URL conversion
- Create shared data URL conversion functions to eliminate code duplication
- Add comprehensive tests for all database types
- Update CHANGELOG.md with detailed feature description
- All blob data is now consistently converted to data URLs with base64 encoding
- Cross-database compatibility ensures identical blob behavior across all backends
- Comprehensive testing validates functionality across PostgreSQL, MySQL, MariaDB, MSSQL, and SQLite
* update changelog
* fmt
* fix: Address clippy linter issues
- Change blob function parameters from Vec<u8> to &[u8] to avoid unnecessary copying
- Use inline format args in data URL construction
- Update function calls to borrow parameters correctly
- Maintain backward compatibility and functionality
* feat: Add smart MIME type detection for BLOB data
- Implement automatic MIME type detection based on file signatures (magic bytes)
- Support common file formats: PNG, JPEG, GIF, BMP, WebP, SVG, PDF, DOCX, XLSX, PPTX, JSON, XML, ZIP
- Automatic fallback to 'application/octet-stream' for unknown formats
- Update CHANGELOG.md with comprehensive feature description
- Add comprehensive tests for MIME type detection functionality
- BLOB data now automatically returns appropriate data URLs:
* PNG files: 'data:image/png;base64,...'
* PDF files: 'data:application/pdf;base64,...'
* SVG files: 'data:image/svg+xml;base64,...'
* Unknown files: 'data:application/octet-stream;base64,...'
- Improves user experience by providing correct MIME types for downloads and displays
- Eliminates need for manual MIME type specification in most cases
* refactor: Make MIME type detection more concise
- Use bytes.starts_with() for cleaner magic byte detection
- Remove verbose comments for each MIME type
- Maintain same functionality with cleaner, more readable code
- Reduce code duplication and improve maintainability
* refactor: Improve MIME type detection with byte strings
- Use byte string literals (b"string") for better readability
- Remove UTF-8 parsing for text-based formats, use direct byte comparisons
- Maintain same functionality with cleaner, more performant code
- PNG: b"\x89PNG\r\n\x1a\n" instead of hex arrays
- JPEG: b"\xFF\xD8" instead of [0xFF, 0xD8]
- Text formats: Direct byte matching without String::from_utf8_lossy
- Update all tests to use new byte string format
* refactor: Extract MIME type detection into separate module
- Create new mime_detection.rs module for better code organization
- Move detect_mime_type() function and tests to dedicated module
- Update sql_to_json.rs to import from mime_detection module
- Remove unused import from functions.rs
- Maintain same functionality with improved code structure
Benefits:
- Better separation of concerns
- Improved code organization and maintainability
- Easier to extend MIME detection in the future
- Cleaner module boundaries
File changes:
- NEW: src/webserver/database/mime_detection.rs (MIME detection + tests)
- MOD: src/webserver/database/mod.rs (add mime_detection module)
- MOD: src/webserver/database/sql_to_json.rs (use mime_detection module)
- MOD: src/webserver/database/sqlpage_functions/functions.rs (remove unused import)
* refactor: Rename mime_detection.rs to blob_to_data_url.rs
- Rename module from mime_detection to blob_to_data_url for better clarity
- Follow project naming conventions (similar to sql_to_json.rs)
- Update all imports and references to use new module name
- Maintain same functionality with improved code organization
File changes:
- RENAMED: src/webserver/database/mime_detection.rs → src/webserver/database/blob_to_data_url.rs
- MOD: src/webserver/database/mod.rs (update module declaration)
- MOD: src/webserver/database/sql_to_json.rs (update import path)
- MOD: src/webserver/database/sqlpage_functions/functions.rs (update import path)
* move
- Add #[must_use] attribute to detect_mime_type for better usage indication
- Replace empty byte check with is_empty() for clarity
- Update tests for improved readability with formatted assertions
- Remove unnecessary blank lines in sql_to_json.rs
Benefits:
- Improved code clarity and maintainability
- Enhanced test readability
* remove old file
* refactor: Update sql_to_json.rs to use new blob_to_data_url module
- Replace direct call to vec_to_data_uri_value with updated import from blob_to_data_url
- Remove deprecated vec_to_data_uri and vec_to_data_uri_value functions for cleaner code
- Maintain existing functionality while improving code organization
* refactor: Simplify MIME type detection logic in blob_to_data_url.rs
- Remove unnecessary empty byte check and streamline conditions for text-based formats
- Enhance readability by consolidating checks for XML and JSON formats
- Maintain existing functionality while improving code clarity
* clippy
* Update documentation for BLOB support and data type handling
- CHANGELOG.md : details on BLOB support and automatic MIME type detection
- Add examples in extensions-to-sql.md illustrating data type conversions and JSON object structure
- Update SQL examples in migrations to reflect new BLOB handling capabilities
