Subject: [PATCH 01/29] fix: reduce dashboard query timeout to 2s to handle
 busy SQLite

The dashboard polls regularly, so long timeouts are unnecessary and cause
DBConnection errors when SQLite is busy. This change:

- Sets dashboard queries to 2s timeout instead of default 15s
- Catches and silently ignores timeouts in dashboard updates
- Updates VideoQueries functions to accept optional timeout parameter
- Inlines count queries in dashboard to apply timeout directly

Since the dashboard polls every few seconds, skipping an update when the
database is busy is acceptable - the next poll will retry.

Subject: [PATCH 02/29] fix: suppress DBConnection timeout errors in dashboard
 queries

Wrap all dashboard queries with rescue/catch to handle timeouts gracefully:
- safe_query/1 returns 0 on timeout for count queries
- safe_query_list/1 returns [] on timeout for list queries
- Prevents error logging when SQLite is busy during sync operations

Dashboard will show default values during timeouts and update on next poll.

Subject: [PATCH 03/29] fix: delegate encoder Broadway to Encode GenServer for
 single-worker protection

The encoder was running multiple concurrent processes because Broadway
was doing the encoding work directly instead of delegating to the
Encode GenServer. This caused duplicate encodings.

Changes:
- Simplified Encoder.Broadway to match CRF searcher pattern
- Delegate all encoding work to AbAv1.encode/1 (Encode GenServer)
- Remove direct port handling from Broadway (now in GenServer)
- Encode GenServer's available?/0 check ensures only one encode at a time
- Remove empty lock.ex file

This matches the CRF searcher architecture which works correctly.

Subject: [PATCH 05/29] fix: run dashboard queries synchronously in test mode

- Prevents DB connection owner exit errors during test cleanup
- Async tasks in tests can outlive the LiveView process causing Sandbox issues
- Added ReencodarrWeb.TaskSupervisor for production async queries
- Removed unnecessary try/catch and Process.alive? checks
- Tests now run cleanly without connection warnings
- Fixed encoder test helper to use fully qualified module name
- Skip MP4 files temporarily due to compatibility issues

Subject: [PATCH 07/29] Update dashboard theme to match favicon aesthetic

- Purple gradient background (from-purple-900 to-purple-800)
- Glassmorphism cards with backdrop blur and white/10 transparency
- Updated all text colors to white/purple shades for contrast
- Progress bars with gradient fills and glow effects
- Larger icon in header (16x16) with drop shadow
- Changed encoder color from green to amber (matching favicon gold)
- Updated sync service component styling
- All buttons now have shadow-lg for depth

Subject: [PATCH 08/29] test: achieve 100% coverage for SharedQueries module
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add comprehensive test suite for SharedQueries:

- case_insensitive_like/2: Database-agnostic LIKE queries
- videos_not_matching_exclude_patterns/1: Pattern filtering (small/large lists)
- videos_with_no_chosen_vmafs_query/0: VMAF cleanup queries
- aggregated_stats_query/0: Statistics calculations for dashboard

Coverage: 64.29% → 100% (+35.71%)
Tests: 4 → 20 tests

Subject: [PATCH 10/29] fix: correct Media test assertions and state
 requirements

- Fix delete_videos_with_path test to use wildcard pattern matching
- Fix delete_unchosen_vmafs test to correctly test videos without chosen VMAFs
- Fix list_chosen_vmafs test to set videos to :crf_searched state
- Fix mark_vmaf_as_chosen test to handle transaction return type
- All 74 Media tests now passing in async mode

From: Mika Cohen <mjc@kernel.org>
Date: Wed, 19 Nov 2025 17:00:14 -0700
Subject: [PATCH 11/29] feat: add Media module tests for queue, library, vmaf,
 and bulk operations

- Add tests for queue operations: get_videos_for_crf_search, get_videos_needing_analysis, list_videos_by_estimated_percent, get_next_for_encoding_by_time, debug_encoding_queue_by_library
- Add tests for library operations: create_library with valid/invalid attrs
- Add tests for vmaf operations: create_vmaf with valid/invalid attrs
- Add tests for bulk operations: reset_all_failures
- Add test for test helpers: test_insert_path
- Fix bug in Media.add_existing_video_messages to handle {:error, :not_found} tuple from get_video_by_path
- Coverage improved from 40.60% to 58.60% (+18%)

Subject: [PATCH 12/29] feat: add comprehensive Media module tests for updates,
 upserts, and operations

- Add tests for update operations: update_video, update_library, update_vmaf
- Add tests for upsert operations: upsert_vmaf (create/update), batch_upsert_videos
- Add tests for reanalysis operations: force_reanalyze_video, debug_force_analyze_video, reset_failed_videos, reset_all_videos_for_reanalysis, reset_all_videos_to_needs_analysis
- Add tests for invalid audio operations: count_videos_with_invalid_audio_args, reset_videos_with_invalid_audio_args
- Add tests for deletion operations: delete_video, delete_library, delete_vmaf, delete_videos_with_nonexistent_paths
- Add tests for changeset operations: change_video, change_library, change_vmaf
- Add tests for video failure operations: get_video_failures, resolve_video_failures
- Skip test for reset_videos_with_invalid_audio_metadata (PostgreSQL-specific array_length)
- Fix credo warnings: replace length/1 with Enum.empty?/1
- Coverage improved from 58.60% to 70.18% (+11.58%)
- Total: 108 tests (23 new tests added)

Subject: [PATCH 13/29] fix: replace PostgreSQL array_length with SQLite
 json_array_length

- Replace PostgreSQL-specific array_length(?, 1) with SQLite json_array_length(?)
- Fix reset_videos_with_invalid_audio_metadata/0 to work with SQLite JSON arrays
- Unskip previously failing test - now passes with SQLite-compatible query
- This was a critical bug preventing the function from working on SQLite databases

Subject: [PATCH 14/29] feat: add comprehensive Media module tests for queue,
 upsert, bulk ops, and diagnostics

- Added 19 new tests covering previously untested functions
- Coverage improved from 61.26% to 67.80% (+6.54%)
- Tests for list_videos_awaiting_crf_search, get_next_for_encoding
- Tests for delete_vmafs_for_video, mark_vmaf_as_chosen with string CRF
- Tests for upsert_vmaf savings calculations and state transitions
- Tests for bulk operations: reset_all_videos_for_reanalysis, reset_videos_for_reanalysis_batched
- Tests for reset_all_videos_to_needs_analysis, debug_force_analyze_video
- Tests for test_insert_path diagnostic function with various scenarios
- All 127 tests passing with comprehensive edge case coverage

Subject: [PATCH 15/29] feat: add direct tests for upsert_video function

- Added 3 tests for upsert_video/1: create, update, and error cases
- Tests verify upsert behavior on path conflict
- Coverage remains at 67.80% (130 tests total)
- Delegates like mark_as_reencoded already covered by VideoStateMachine tests

Subject: [PATCH 22/29] fix: simplify dashboard queries and add state
 transitions for Broadway deduplication

- Remove expensive JSON fragment codec checks from CRF search queries
- Simplify queries to use indexed state column only (v.state == :analyzed)
- Add mark_as_crf_searching() and mark_as_encoding() to persist state transitions
- Call state transitions immediately when CRF search/encode starts
- Prevents Broadway infinite loops by marking videos before port opens
- Dashboard queries now timeout-safe and much faster
- Codec filtering happens at Rules.build_args stage instead of query time

Subject: [PATCH 23/29] feat: add exponential backoff with jitter for database
 busy errors
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Created Reencodarr.Core.Retry module for centralized retry logic
- Exponential backoff: 100ms → 200ms → 400ms → 800ms → 1600ms
- Added jitter (up to 50% of base delay) to prevent thundering herd
- Applied retry logic to VideoUpsert.batch_upsert for sync operations
- Applied retry logic to VideoStateMachine.mark_as_analyzed
- Improved analyzer error reporting to include failure reasons

- Dashboard now gracefully handles client checkout timeouts during sync
- Returns default values (0 or []) instead of crashing when DB is under heavy load
- Prevents error logs when database connection pool is saturated

- Only log throughput metrics when there's recent activity (avg > 0)
- Prevents spam of 'consecutive improvements' when no batches are being processed
- Performance monitor continues to run but stays quiet when idle

Subject: [PATCH 27/29] fix: validate required mediainfo fields before marking
 videos as analyzed

- Check for bitrate, width, height before transition to analyzed state
- Prevents validation errors when videos have existing mediainfo in DB but missing required fields
- Skips transition and logs when fields are missing instead of failing repeatedly
- Videos with missing fields will be reprocessed through mediainfo pipeline
- Refactored to reduce nesting for credo compliance

Subject: [PATCH 29/29] refactor: rename analyzer functions for clarity
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- transition_video_to_analyzed → decide_video_processing_path
  Makes it clear this function decides between :analyzed AND :encoded states

- determine_video_transition_decision → check_encoding_requirements
  Pure function that returns {:skip_encoding, reason} or {:needs_encoding, reason}

- persist_analyzed_state/persist_encoded_state → apply_processing_decision
  Single private function handling DB persistence based on decision

- Updated all tests to use new function names and correct assertions

This eliminates the confusing naming where multiple functions with similar
names (transition_video_to_analyzed, persist_analyzed_state,
Media.mark_as_analyzed, VideoStateMachine.mark_as_analyzed) did completely
different things, causing maintenance nightmares.
