Chord's shared watch: listeners take a tagged call, { kind: "value", value, ops, retired } or
{ kind: "failed", error }; a recoverable failure keeps the watch open and the next value arrives as
[["r", value]]; WatchEnd is tagged by kind, and an aborted context ends a watch "aborted".
Durable: observers take the watch's shapes (advance(call, ctx), end(end)); onReport(report) with
report.kind and report.error, session_failed is storage_failed; subscribeCommits is observeCommits;
SessionEnd and ReportFrom are tagged by kind; FileChange is tagged and file watchers stop with
stop(ctx); CompactionFailure and CompactionStatus name their trigger (pi.live version 2 with a
migrate); the task_outdated report uses the scheduler's reasons; TaskInspection's ready is pending;
DocumentCommitChange is tagged. Stored formats are unchanged.
Durable publishes a stored commit inside Storage.commit's adopt: the
telemetry events, its own observers (document watches, conversation
views, task graph, scheduler, waits), and a dispatch of host
subscribeCommits listeners one microtask later, before every wait and
abort the commit triggers. A commit the storage rejects after adoption is
published before the Session fails; a throwing telemetry adapter is
reported as host_error "telemetry" instead of rejecting a durable commit.
Chord's watch listeners take one change object, { value, ops, retired }
({ value } for native watches); retirement is a flag, not an end.
Durable's document watches follow their address, and a task document's
watch ends after its retirement call. New synchronous observers for
adapters: observeDoc, observeConversation, observeTaskGraph; the watches
are built on them. The env file watcher's change type is renamed
FileChange.
- required watch(targets, onChange): missing targets, recursive targets
with excludes, paths/overflow/error changes, native or polling mode
- NodeExecutionEnv: fs.watch events trigger rescans; changes are snapshot
differences plus event paths; watchers for new directories before rescans;
polling on network and FUSE file systems; directory budget
- conformance cases in native and polling mode
- FileSystem.openBinaryReader(): positional reads of one opened regular file, noFollow
- FileSystem.openDirReader(): paged listings, vanished entries skipped
- Shell.exec() accepts an argv array (no shell); onOutput reports the stream
- Env conformance suite in /testing, run for NodeExecutionEnv
- Work-branch workflow running env tests on Linux, macOS and Windows
