Thread Split automatically splits long-running threads into numbered parts when post or page thresholds are reached, while keeping watchers, navigation, and reading position intact. Define a threshold once globally, override per forum, or override per thread. When a thread crosses the limit, a continuation thread is created, watchers and active readers are carried over, and a chain links every part together with prev/next navigation.

Features

Threshold-based auto-split

Trigger split by post count or page count
Three-tier cascade: global default -> per node configuration -> per-thread override

Two split modes

Grace mode: wait N minutes of inactivity before splitting to avoids cutting an active conversation mid-flow
Hard mode: split immediately when the threshold is crossed

Chain navigation

Numbered parts with configurable title template
Chain menu with parts index and next / previous links

Watcher and viewer continuity

Existing thread watchers migrated to the new part (configurable)
Users currently viewing the old thread receive a "continued" alert with opt-out

Configurable continuation post

Templated continuation post auto-inserted into the new part
Title template editable globally or per forum

Thread move handling

Choose what happens when a chain part is moved between forums:
- Detach the moved thread (default)
- Allow the chain to span forums
- Move the whole chain together

Error log and stuck-split recovery

Dedicated admin Thread split error log page under Logs, with filters by phase, chain, and date range
Every deferred job (split execution, watcher migration, viewer alerts, parts-summary rebuild, whole-chain move) wraps failures with full context and writes them to the log
Background cron detects stuck or orphaned pending splits, retries them once, and clears the queue automatically
Old log entries auto-prune after 30 days; manual "Clear all" available

Built for big boards in mind

Query-budgeted: zero queries on disabled forums and one batched query for forum listings regardless of size.

CLI Commands

Code:

mc-threadsplit:show-chain <chain_id> — diagnostic dump for a chain (parts, post counts, watcher counts)
mc-threadsplit:cleanup-orphans — find and delete chain_thread rows pointing to non-existent threads, plus chains with zero members
mc-threadsplit:detach <thread_id> — detach a thread from its chain and renumber survivors
mc-threadsplit:dissolve <chain_id> — delete a chain entirely; member threads remain unchained
mc-threadsplit:relink <thread_id> <chain_id> <position> — attach an unchained thread to an existing chain at a given position
mc-threadsplit:renumber <chain_id> — recompute part_number 1..N ordered by first post date (idempotent)
