The DB-update + deep-scan automation monitor used a hard 2-hour TOTAL cap
(while elapsed < 7200). It tracked progress but only used it to print a stall
warning — the only thing that actually timed out was wall-clock. So a large
library that scans for >2h while progressing fine (reported: 4781 artists) trips
the cap and the automation card flips to 'error: timed out after 2 hours' even
though the scan thread is healthy and still running (the timeout never cancels
it, which is why it keeps progressing in the logs after the 'error').
Time out on STALL, not total runtime:
- 30 min with NO progress -> error ('stalled'); catches a genuinely hung scan.
- 10 min idle -> warning (repeats); unchanged heads-up.
- 24h absolute backstop, purely a runaway-loop guard.
- An actively-progressing scan keeps resetting the idle clock, so it never
times out no matter how many hours the whole library takes.
- Progress is judged on (processed, progress, current_item) so a slow stretch
where the rounded % holds steady (but the artist keeps changing) isn't a
false stall.
The decision is extracted into a pure, testable scan_wait_action(); both the
deep-scan and full-refresh handlers share the monitor loop, so both are fixed.
Tests: tests/test_scan_wait_action.py (9) — headline regression (5h/12h total
but progressing -> 'continue', not timeout), finished/stall-warn/stall-timeout/
abs-cap thresholds, and ordering. 280 automation tests still pass.
Final commit of the automation-handler refactor. With this commit
every closure that used to live in
`web_server._register_automation_handlers` is now a top-level
function in `core/automation/handlers/`.
Handlers extracted in this commit:
- start_database_update + deep_scan_library
-> core/automation/handlers/database_update.py
Both share the db_update_state monitoring pattern (poll until
status flips, stall detection emits warning at 10 min, 2-hour
outer timeout). Lifted into a shared `_run_with_progress` helper
inside the module so the per-handler bodies stay tiny.
- run_duplicate_cleaner -> core/automation/handlers/duplicate_cleaner.py
- start_quality_scan -> core/automation/handlers/quality_scanner.py
- clear_quarantine, cleanup_wishlist, update_discovery_pool,
backup_database, refresh_beatport_cache
-> core/automation/handlers/maintenance.py
Grouped because each body is short (~20-50 lines) and they share
no state — splitting into per-handler files would just add import
noise.
- clean_search_history, clean_completed_downloads, full_cleanup
-> core/automation/handlers/download_cleanup.py
Grouped because all three reach the download orchestrator,
tasks_lock, and download_batches/download_tasks accessors. The
full_cleanup multi-step orchestration shares phase-detection
logic with clean_completed_downloads.
- run_script -> core/automation/handlers/run_script.py
- search_and_download -> core/automation/handlers/search_and_download.py
`AutomationDeps` grew with the new dependency surface:
- get_db_update_state + db_update_lock + db_update_executor +
run_db_update_task + run_deep_scan_task
- get_duplicate_cleaner_state + duplicate_cleaner_lock +
duplicate_cleaner_executor + run_duplicate_cleaner
- get_quality_scanner_state + quality_scanner_lock +
quality_scanner_executor + run_quality_scanner
- download_orchestrator + run_async + tasks_lock +
get_download_batches + get_download_tasks +
sweep_empty_download_directories + get_staging_path
- docker_resolve_path + get_current_profile_id +
get_watchlist_scanner + get_app + get_beatport_data_cache
- set_db_update_automation_id (writes the legacy global so the live
DB-update progress callbacks still living in web_server.py keep
emitting against the active automation card)
`web_server._register_automation_handlers` is now ~50 lines: build
deps once, call register_all. The 667-line block of remaining
closure definitions and engine register calls is gone.
The final orphan was the `_db_update_automation_id` module global —
the DB-update progress callbacks at line ~14080 still read it
directly, so the extracted database_update handler propagates the
automation id through `deps.set_db_update_automation_id` (a closure
in web_server that writes the global). When the legacy callbacks
get extracted in a future PR the setter goes away.
Tests:
- tests/automation/test_handlers_maintenance.py adds 21 boundary
tests covering every newly-extracted handler shape: guard
short-circuits (already-running returns skipped), deps wiring
(set_db_update_automation_id called with the right id),
exception swallow contract, status returns, path-traversal
blocked in run_script, source-mode skip in clean_search_history,
active-batch skip in clean_completed_downloads, etc.
- 3244 tests pass (was 3223 — 21 new), no regression.
web_server.py: 35,593 -> 34,220 lines (-1,373 net across 3 commits).
Issue #1 from the extraction punch list is now COMPLETE.
