A team launch creates many directories/files in quick succession (worktrees,
inboxes, session logs), and each addDir/unlinkDir event triggered a full
TeamTaskWatchRegistry reconcile that tore down and recreated the entire chokidar
watcher (re-opening a kqueue fd per watched file on macOS). Profiling a 6-member
mixed-team launch showed kqueue churn (kevent) as a top native cost and watcher
rebuild as the top remaining main-thread JS cost after the transcript fix.
Debounce the event-driven reconcile (250ms) so a burst collapses into one rebuild.
collectTargets re-reads the current directory state and emitExistingFilesForNewTargets
backfills files created before the rebuild, so no change is missed; requestReconcile,
startup, and the periodic 30s reconcile stay immediate. Adds a test asserting a
burst of addDir events yields a single rebuild.
During launch, the bootstrap-wait loop polls each member and, per member, re-read
and re-JSON.parsed the same growing transcript tail (readRecentBootstrapTranscriptOutcome
was the top main-thread JS hotspot at ~21% during bootstrap, ~40% with its helpers).
The same file was parsed once per member per poll.
Memoize the parsed tail by (filePath, mtime, size) in a shared cache so the file is
read + parsed once per change and reused across all members. The per-member filter
and failure/success scan is byte-for-byte the same logic; only the redundant read +
JSON.parse is removed. Cache is bounded (LRU, same cap as the outcome cache) and
invalidated on mtime/size change, matching the existing outcome cache semantics.
Adds a test asserting the tail is parsed once and shared while per-member outcome
detection is unchanged.
The main process watched every team directory under ~/.claude/teams (one shallow
chokidar target per team root, per team inboxes, and per task dir). On macOS this
falls back to kqueue, which needs one fd per watched file, so a workspace with
many teams kept ~1600 descriptors open and made startup and reconcile work scale
with the number of teams on disk.
Scope the team-root and task watching to teams that are running or currently
engaged in the UI. The teams root and every team's inboxes are still watched for
all teams, so cross-team message delivery, the lead inbox->stdin relay, and
notifications are unchanged. Idle teams are static, so dropping their team-root/
task watches is safe; opening a team (getData) or launching it re-adds it via an
immediate watch-scope refresh. The provider falls back to watching every team
when unset, and the EMFILE polling fallback is intentionally left unscoped so a
scope change can never look like a deletion.
Measured on a 162-team workspace: open team fds 1600 -> 730, with team-root
watching restored the moment a team is opened or goes live.
listRuntimeProcesses spawned a full `ps -ax` on every call with no caching.
It is invoked very frequently while a team runs: runtime liveness/telemetry
snapshots are rebuilt whenever a team file changes (invalidateRuntimeSnapshotCaches
fires from ~25 sites), so the main process ended up forking ps dozens of times
per second, which is expensive from the large Electron main process and pegged
its CPU.
Add a 1s TTL cache plus in-flight coalescing on the single ps spawn point.
Liveness/telemetry callers already tolerate ~2s staleness via their own snapshot
caches and the OS process table changes negligibly within a second, so this caps
ps to <=1/s without affecting liveness correctness. Measured posix_spawn dropped
from ~146/s to ~11/s with a team running.
- Extract symlink source/target paths directly from the error message
instead of reconstructing them from process.env (Codex P2 review)
- Add extractSymlinkSourcePath and extractSymlinkTargetPath functions
- Update ensureOpenCodeProfileNodeModulesJunction to accept optional
errorMessage parameter and use extracted paths from it
- Fix unused imports in test (remove 'os', replace 'beforeEach' with
'afterEach' per CodeRabbit review)
- Widen fs.statSync mock signatures to use Parameters<typeof fs.statSync>
per CodeRabbit review
- Add tests for new extraction functions
- Pass errorMessage to ensureOpenCodeProfileNodeModulesJunction calls
in CLI client tests
On Windows 10 without Developer Mode, the OpenCode runtime fails to create
a symlink from shared-cache/config-node_modules to the profile's
node_modules directory. The EPERM error blocks the entire OpenCode provider
catalog, leaving it unavailable.
Changes:
- New openCodeWindowsNodeModulesJunction module that pre-creates a Windows
directory junction (no Developer Mode required) before the runtime call
when an EPERM symlink error is detected
- On Windows, loadView and loadProviderDirectory now detect EPERM symlink
errors, extract the profile ID, create the junction, and retry the
runtime command once before falling back to the error response
- Updated diagnostic hints to accurately reflect that the runtime does not
yet include junction fallback, and that the next runtime update will
include it
- Added unit tests for the junction module and retry behavior
