Shared cache/rescan-duration logic in common.sh now takes an arr_type param instead of being Lidarr-specific, so Sonarr and Radarr cleanup scripts get the same cache-first fetch + rescan-aware retry Lidarr had. Avoids redundant full-library API calls across scripts run back to back, and stops false failures when a fetch lands mid-rescan.

|
# PURPOSE
|
|
# ─────────────────────────────────────────────────────────────────────────────
|
|
# Populates the shared tracked-data cache (see arr_get_tracked_data() in common.sh) for
|
|
# Lidarr, Sonarr, and Radarr once at array start, before any other script needs it. Without
|
|
# this, each arr's cache stays cold from boot until whichever script happens to touch that
|
|
# arr first writes through — which could be hours, depending on the daily schedule. One-shot:
|
|
# runs and exits. Originally Lidarr-only (lidarr_cache_prefill.sh, 2026-07-16), generalized
|
|
# the same day to cover all three arrs once the cache mechanism itself was generalized.
|
|
#
|
|
# ==============================================================================================
|
|
# OPERATIONAL MODEL
|
|
# ==============================================================================================
|
|
#
|
|
# Each arr's container may still be starting when this fires (array just started) — retries
|
|
# reaching that arr's API for up to ARR_PREFILL_WAIT_MINUTES before giving up on it and moving
|
|
# to the next. Not fatal if one never comes up in time; that arr's cache just stays cold until
|
|
# the next script writes through naturally, exactly as it would without this script existing.
|
|
# An arr not configured on this host (e.g. Lidarr is HOST1-only) is skipped cleanly.
