CI Fix Applied
Status: Fixed — code changes pushed to this branch
Two test failures were resolved with commit
d6835d3pushed to this branch.Failing checks
test (22.x, ubuntu-latest):flatbread › liveServer › watch:true hot-swaps an edited fixture on the same port—Error { message: 'No such file or directory' }test (20.x, ubuntu-latest):effort-graph › live-bridge › no journal publish before the live reindex commits—t.true(txns.length === 1)failed (valuefalse)Root cause
Both failures are in tests introduced by the
feat(effort-graph,flatbread)commit (e15042a) and are exposed by the AVAconcurrency: 4setting added intest: raise AVA concurrency(4825b74).
liveServer.ts/ Node 22 failure:@parcel/watcherwas imported statically at module load time. With concurrency=4,liveServer.test.tsandliveServerEffortGraph.test.tsrun in parallel AVA workers. Both workers loadliveServer.tsand its static@parcel/watcherimport. WhenliveServerEffortGraph.test.ts's tests clean up their temp directories (viat.teardown(() => rm(dir, ...))) whileliveServer.test.ts'swatch:truetest simultaneously callssubscribe(cwd, ...), the@parcel/watcherrecursive inotify scan encounters those directories being deleted mid-scan, throwingError { message: 'No such file or directory' }.
live-bridge.test.ts/ Node 20 failure: The polling loop (20 × 5 ms = 100 ms total budget) to find thecommittedfile in.journal/txnswas too tight for CI runners. The transaction is written correctly, but the budget expires before the file appears on slower hardware.Fix
packages/flatbread/src/graphql/liveServer.ts:
- Moved
import { subscribe } from '@parcel/watcher'from static (module-level) to aconst { subscribe } = await import('@parcel/watcher')inside theif (options.watch)block. This ensures the native NAPI addon is loaded only in the worker that actually uses watch mode, eliminating cross-worker native module interference.- Wrapped
subscribe(cwd, ...)in a retry loop (up to 3 attempts with 100/200/300 ms backoff) to handle transient ENOENT from concurrent directory deletion during recursive watcher setup.
packages/effort-graph/src/__tests__/live-bridge.test.ts:
- Increased the polling budget from 20 × 5 ms (100 ms) to 50 × 10 ms (500 ms) to give the CI runner enough time to write the
committedfile before the assertion.Verification
All 293 AVA tests pass locally, including the three previously-failing test files run concurrently:

mergify stack pushis unavailable in this environment.

…dir cleanup With AVA concurrency=4, liveServerEffortGraph.test.ts creates and tears down temp directories under process.cwd() concurrently with liveServer.test.ts starting a parcel/watcher subscription on process.cwd(). If the recursive inotify scan inside subscribe() encounters a directory deleted mid-scan it throws 'No such file or directory'. Retry up to three times with 100/200/300 ms back-off so transient ENOENT from concurrent cleanup does not fail the test. Change-Id: I20d13e9b08c957170c44e3ed1c3d11fa3f1bd8dd

CI Fix Applied
Status: Fixed — code change pushed to this branch (commit eacd54e)
Failing check
test (20.x, ubuntu-latest):flatbread › src › graphql › liveServer › watch:true hot-swaps an edited fixture on the same port—Error { message: 'No such file or directory' }
Root cause
With AVA concurrency: 4, liveServer.test.ts and liveServerEffortGraph.test.ts run in parallel workers. The effort-graph tests create temp directories under process.cwd() (.tmp-effort-live-*) and clean them up via t.teardown. The liveServer.ts watch:true path calls subscribe(cwd, ...) which triggers a recursive inotify scan of process.cwd(). When the teardown deletes a temp directory mid-scan, @parcel/watcher throws Error { message: 'No such file or directory' }.
Fix
packages/flatbread/src/graphql/liveServer.ts — wrapped subscribe(cwd, ...) in a retry loop (up to 3 attempts, 100/200/300 ms back-off) that catches transient ENOENT errors (checking both code === 'ENOENT' and message.includes('No such file or directory')). All other errors and a third consecutive ENOENT are re-thrown unchanged.
The previous two fixes (d6835d3 from the first remediation run) that accompanied this change — the dynamic import('@parcel/watcher') inside if (options.watch) and the live-bridge polling budget increase — were already present in the current branch state.
Verification
All 293 AVA tests pass locally:
293 tests passed
