From 008706a7fa2f5773ac9becceddcfe77dd47d58c1 Mon Sep 17 00:00:00 2001 From: John O'Keefe Date: Sun, 29 Mar 2026 21:12:27 -0400 Subject: [PATCH] docs: update implementation plan with DOUBLE PRECISION and complete integration tests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Phase 6.2 implementation: Add comprehensive integration test code to plan. Documentation Updates: - Changed community_rating from DECIMAL(3,1) to DOUBLE PRECISION throughout plan - Fixed function name references: processNewMediaItems → processMediaFile (correct name) - Added complete integration test implementation (TestComicMetadataExtraction, TestReadingDirectionAPI, TestUniversalMetadataFields, TestComicSpecificFields) - Replaced skeleton TestMergeMetadata with actual test code using setupTestServer - Added context-based location markers (3 lines before/after) for easier code navigation - Removed TODO comment reference (doesn't exist in current code) - Updated all line number references and added plan update summary - Verified test helper usage: setupDeviceTest for library creation Integration Tests Added: - Full comic metadata field testing (manga_type, reading_direction, series_count, volume, imprint, age_rating, community_rating as pgtype.Float8, story_arc, is_black_and_white) - Reading direction API testing (rtl, ltr, auto filtering) - Universal field testing for both comic and ebook libraries - Comic-specific field testing (alternate_info JSONB, scan_information, summary, metadata_notes) All tests use proper test_helpers pattern with setupDeviceTest and verify DOUBLE PRECISION storage for CommunityRating field.

This is the actual function name in media_scanner.go. + +9. **Changed community_rating to DOUBLE PRECISION**: Changed from `DECIMAL(3,1)` to `DOUBLE PRECISION` for simpler code. This eliminates the awkward `pgtype.Numeric` conversion and uses simple `pgtype.Float8` instead. Matches ComicInfo.xml float64 type naturally with no string conversion needed.
