test: pull five batch-flaky files out of the parallel batch - #40419
Conversation
These failed inside the shard's parallel batch and passed when rerun alone in recent CI builds: - cli/inspect/bun-inspector-protocol.test.ts - cli/install/migration/migrate.test.ts - js/bun/resolve/bun-main-entry-point.test.ts - js/node/tls/renegotiation.test.ts - js/sql/postgres-tls-ctx-leak.test.ts No-Verification-Needed: test-runner config lists only

LGTM — straightforward CI config change moving five batch-flaky test files to the serial lane.
What was reviewed:
- Verified all five entries were added to both
excludeFiles(runner-read) andparallel-denylist.txt(regenerator-read), and that each file's parent dir is indirsso the exclusion is live. - Checked the
_meta.stats.excludedcount bump (361 → 366) matches the five additions. - Confirmed insertions preserve the existing sort order in both files.
Extended reasoning...
Overview
This PR adds five test files to the parallel-batch exclusion lists so the CI runner executes them serially instead of inside the shard's parallel batch. Two files are touched: test/parallel-allowlist.json (the excludeFiles array read by scripts/runner.node.mjs, plus the _meta.stats.excluded counter) and test/parallel-denylist.txt (read by scripts/update-parallel-allowlist.mjs so a future regeneration doesn't re-qualify them). No runtime, native, or test-logic code is modified.
Security risks
None. This is a CI test-scheduling allowlist; it does not affect the built binary, any user-facing behavior, or which tests run — only whether these five files run inside the parallel batch or on their own.
Level of scrutiny
Low. This is a mechanical, additive config edit following the exact pattern already used for ~360 other excluded files. The worst-case failure mode is a slightly slower CI shard (five more files run serially) or, if a path were mistyped, the exclusion silently not applying — neither is a correctness or safety issue. I confirmed each added path's directory (cli/inspect, cli/install/migration, js/bun/resolve, js/node/tls, js/sql) appears in the dirs list, so the entries are meaningful.
Other factors
The excluded stat was correctly bumped from 361 to 366. Entries are inserted in the same sort order as their neighbors in both files. The PR description explains the motivation (batch-flaky annotations) and matches the header comment in parallel-denylist.txt describing exactly this workflow. No prior reviewer comments to address.

The required checks remain outstanding because bun is unavailable. Run both commands in an environment with bun installed and confirm that they pass.

What does this PR do?
Five test files have been failing inside the shard's parallel batch and then passing when the runner reruns them alone (the "in the parallel batch … passed alone" flaky annotation). This takes them out of the batch so they always run on their own:
cli/inspect/bun-inspector-protocol.test.tscli/install/migration/migrate.test.tsjs/bun/resolve/bun-main-entry-point.test.tsjs/node/tls/renegotiation.test.tsjs/sql/postgres-tls-ctx-leak.test.tsThey're added to
test/parallel-denylist.txt(soscripts/update-parallel-allowlist.mjsnever re-qualifies them) and toexcludeFilesintest/parallel-allowlist.json(whatscripts/runner.node.mjsreads).How did you verify your code works?
Confirmed each file was previously allowlisted (its dir in
dirs, not inexcludeFiles) and is now excluded. CI on this PR will show whether the batch annotations for these files stop.
