Module runtime_drain 

Structs

DrainBatchOutcome

StandaloneConfigureMaintenance

Tracks deferred configure work for the standalone NDJSON loop. The attached- daemon (subc) path schedules this work through its executor instead.

Constants

BREAKER_TRIP_THRESHOLD

LSP_EVENT_DRAIN_BATCH_CAP

MAX_RETRY_ATTEMPTS

WATCHER_BATCH_INLINE_CAP

WATCHER_DRAIN_SLICE_BUDGET

WATCHER_PATH_DRAIN_BATCH_CAP

Functions

any_build_in_flight

Return true when any background build-completion receiver is currently set.

drain_build_completions

Drain all background build-completion receivers in standalone order.

drain_callgraph_store_events

drain_configure_warning_events

drain_deferred_configure_maintenance

drain_inspect_events

drain_lsp_events

drain_lsp_events_bounded

drain_search_index_events

drain_semantic_index_events

drain_semantic_refresh_events

drain_watcher_events

Drain pre-filtered watcher events and apply cache invalidations on the dispatch thread. The watcher filter thread owns notify receive/decode, metadata filtering, ignore matching, root-deleted detection, and path coalescing; this drain only reacts to compact control events and surviving paths because the cache/index state below is not Send.

drain_watcher_events_bounded

mark_semantic_corpus_refresh_success

note_configure_maintenance_yield

Report cooperative configure work displaced by already-buffered requests. Bursty clients may trigger many unit boundaries, so emit at most once per five seconds while preserving the queued count from the observed boundary.

record_semantic_refresh_transient_failure

refresh_callgraph_store_for_watcher

refresh_corpus_after_ignore_change

refresh_project_after_watcher_rescan

refresh_project_corpus

schedule_semantic_refresh_retry

semantic_corpus_refresh_in_progress

semantic_refresh_circuit_is_open

shutdown_idle_lsp

Shut down language servers for a standalone runtime whose last request is older than idle.lsp_ttl_minutes. Subc uses the same helper with its own per-root activity stamp.

shutdown_idle_lsp_at

spawn_search_corpus_refresh

spawn_standalone_log_maintenance

Keep shared log-retention I/O off the standalone request loop. The logging module retains its hourly sweep cadence; this coarser gate avoids spawning a no-op thread on every 250 ms idle tick.

watcher_path_is_callgraph_indexed

A file the callgraph STORE would have indexed at cold-build time. The store indexes every file walk_project_files yields (i.e. any detected language), not just the trigram SOURCE_EXTENSIONS set. Gating the store’s watcher refresh on the narrower trigram set left edits to Java/C/C++/C#/Kotlin/Ruby/ PHP/… (all of which the store extracts calls for) serving stale results until a full rebuild. Mirror cold-build exactly so refresh coverage == index coverage.

watcher_path_is_ignored_by_current_matcher

watcher_path_is_semantic_source

watcher_path_is_source

watcher_path_is_tsconfig

A tsconfig.json / jsconfig.json (including variant names like tsconfig.base.json). A change to any of these can shift TypeScript build membership (which files tsc checks), so the status-bar membership cache must be invalidated. Deliberately broad on the variant suffix and ignorant of extends graphs: the cache is cleared wholesale on a match, and base configs almost always follow the tsconfig*.json naming. Non-standard base names are covered on the next tsconfig.json change or configure.
