EPGOAT Documentation - Work In Progress

Documentation Update Checklist - Phase 2 & 3

Status: Active Last Updated: 2025-11-02 Related Docs: System Overview, Maintenance Guide, TODO Backlog

Date: 2025-11-02 Changes: Multi-provider architecture (VOD filtering, config manager, pattern matching)

✅ COMPLETED

1. System-Overview.md - COMPLETE

- [x]

Updated version to 2.1, date to 2025-11-02 - [x] Added Provider Config Manager to component diagram - [x] Added VOD Detector to component diagram - [x] Added Provider M3U Parser to component diagram - [x] Added 3 new component descriptions (components 0-2) - [x] Updated component numbering (0-10) - [x] Updated database table count (24 → 27) - [x] Added 3 new tables to Providers & Patterns section: - [x] provider_patterns with full schema - [x] tvg_id_mappings with full schema - [x] vod_filter_patterns with full schema

File: Documentation/03-Architecture/System-Overview.md

🔶 HIGH PRIORITY (This PR)

2. Database Schema Documentation

Status: Pending File: Documentation/05-Reference/Database/Schema.md (if exists)

Actions Needed: - [ ] Check if file exists - [ ] If exists, add 3 new tables with complete specifications: - [ ] provider_patterns - columns, indexes, relationships, example queries - [ ] tvg_id_mappings - columns, indexes, relationships, example queries - [ ] vod_filter_patterns - columns, indexes, relationships, example queries - [ ] Update table count in header - [ ] Add migration reference (006_provider_patterns_alter.sql)

If file doesn't exist: Create it using System-Overview.md as source

3. Quick-Start Guide

Status: Pending review File: Documentation/04-Guides/Quick-Start.md

Actions Needed: - [ ] Read current guide - [ ] Check if M3U parsing workflow is documented - [ ] If yes, verify if it mentions: - [ ] Provider config manager - [ ] VOD filtering - [ ] Config cache location (backend/config/providers/) - [ ] Update if outdated - [ ] Test walkthrough still works with new architecture

Risk: MEDIUM - Setup instructions may reference old parse_m3u_file()

4. Command Reference

Status: Pending review File: Documentation/04-Guides/Command-Reference.md

Actions Needed: - [ ] Read current command reference - [ ] Add new scripts: - [ ] test_config_manager.py - Test provider config loading - Usage: python test_config_manager.py - Purpose: Validates config manager, generates YAML cache - Output: Config statistics, cache file location - [ ] Update backend/epgoat/cli/run_provider.py description if config loading changed - [ ] Add examples for: - [ ] Loading provider config from cache - [ ] Force refreshing config from database - [ ] Syncing config for specific provider

Risk: LOW - New functionality, easy to document

🔷 MEDIUM PRIORITY (This Week)

5. Match Failures Troubleshooting

Status: Pending update File: Documentation/07-Troubleshooting/Match-Failures.md

Actions Needed: - [ ] Read current troubleshooting guide - [ ] Add new troubleshooting sections: - [ ] VOD Filtering Issues: - Problem: Live channels being filtered as VOD - Solution: Review vod_filter_patterns table, disable problematic patterns - Example: Check pattern match statistics - [ ] Pattern Matching Issues: - Problem: Channels not matching despite patterns existing - Solution: Check pattern priority, verify is_active flag - Example: Query provider_patterns by priority - [ ] Config Cache Issues: - Problem: Changes to DB patterns not reflected - Solution: Force refresh cache (force_refresh=True) - Example: Delete YAML cache to force reload - [ ] Identification Method Issues: - Problem: Provider using wrong identification method (name vs tvg-id) - Solution: Update providers.identification_method column - Example: Switch from name_prefix to hybrid

Risk: MEDIUM - Users may encounter these issues

6. Maintenance Guide

Status: Pending update File: Documentation/09-Meta/Maintenance-Guide.md (check if exists)

Actions Needed: - [ ] Check if file exists - [ ] Add cache maintenance procedures: - [ ] Cache Location: backend/config/providers/{slug}.yml - [ ] Cache TTL: 24 hours (configurable via max_cache_age_hours) - [ ] Force Refresh: Use get_config(slug, force_refresh=True) - [ ] Sync from DB: Use sync_from_db(slug) or sync_from_db() for all - [ ] Cache Staleness Check: File mtime + sync metadata timestamp - [ ] Manual Cache Clear: Delete .yml files, they'll regenerate - [ ] Document when to refresh cache: - After adding new patterns to database - After updating provider identification method - After modifying VOD filter patterns - When troubleshooting pattern matching issues

Risk: LOW - Operational knowledge, helps admins

7. Performance Issues Guide

Status: Pending update File: Documentation/07-Troubleshooting/Performance-Issues.md

Actions Needed: - [ ] Read current performance guide - [ ] Add VOD filtering performance section: - [ ] Massive Performance Gain: VOD filtering provides 53x speedup - [ ] TPS Example: 387k → 32k channels (91.7% filtered) - [ ] When to Review: If filtering too aggressive or too lenient - [ ] Statistics: Check vod_filter_patterns.match_count - [ ] Add config caching performance section: - [ ] Cache Performance: 8s → 150ms (53x faster) - [ ] D1 API Savings: 100% reduction when cache is fresh - [ ] When to Use: Always in production, optional force refresh for debugging - [ ] Cache Miss Cost: 8 seconds on first load, instant thereafter

Risk: LOW - Nice-to-have performance context

📋 VERIFICATION CHECKLIST

Before marking documentation as complete:

For Each Updated File: - [ ] Read the documentation file completely - [ ] Compared with actual code behavior - [ ] Tested all code examples (if applicable) - [ ] Checked all links work - [ ] Verified code locations exist and are accurate - [ ] Updated "Last Updated" date - [ ] No broken references - [ ] No TODO items without explanation

Cross-References: - [ ] Links from System-Overview.md to other docs still work - [ ] Command-Reference correctly points to script locations - [ ] Troubleshooting guides reference correct component names - [ ] ADRs (if any) reference updated architecture

🎯 SUCCESS CRITERIA

Documentation update is complete when:

  1. ✅ System-Overview.md reflects Phase 2 & 3 changes (DONE)
  2. ☐ Database Schema documentation includes 3 new tables
  3. ☐ Quick-Start validated against new architecture
  4. ☐ Command-Reference includes new scripts and updated usage
  5. ☐ Troubleshooting covers VOD filtering, patterns, cache issues
  6. ☐ All verification checks passed

📝 NOTES

Architecture Changes Summary

Phase 2: VOD filtering + provider-aware M3U parsing Phase 3: Config manager with hybrid storage (DB + YAML cache)

Key Impact Areas

  1. Performance: 53x faster parsing, 53x faster config loads
  2. Scalability: Multi-provider support with 3 identification methods
  3. Storage: 3 new database tables (72 patterns, 26 VOD filters for TPS)
  4. Developer Experience: YAML cache enables offline development

Files NOT Requiring Updates

  • ✅ Phase documentation (PHASE_2_PARSER_COMPLETE.md, PHASE_3_CONFIG_MANAGER_COMPLETE.md) - Already complete
  • ✅ Migration files - Already applied to staging
  • ✅ Test files - Internal documentation
  • ✅ ADRs - No architecture decisions documented yet (consider creating)
