test: fix three load-only test failures at the cause - #4286
Conversation
- json: the compressed-gate test pushed 32 MiB through pako without ever reaching the gate. An internal maxGroupBytes budget lets it hit the gate with a few bytes, and it now fails when the gate measures plaintext. - net: the declaration-import check ran tsc inside bun test. It now runs over dist/ in common/package.ts after every package build. - moq-tokio: noq_cert_reload skips on the listener's own watcher failure instead of a racy probe, and waits on the fingerprints instead of sleeps.

When an emitted declaration contains import type Foo from "./foo.js", as the watch and publish UI declarations do for their element classes, this regex never records the import. Marking that default export @internal can therefore leave the published .d.ts importing a nonexistent default while the new package check still succeeds. Parse default imports as the name default, preferably through the existing parser dependency, and add a regression case.

Fixed in 5ae6337: the parser now uses the AST from @babel/parser (already used by deps.ts), so a default import is checked as default. Regression test added.

WalkthroughThe JavaScript package check now validates imports in emitted declaration files. The snapshot encoder accepts a configurable group-size limit, and its overflow test uses a smaller budget. The certificate reload test removes fixed delays and checks for a fingerprint change. The changes also update test guidance and add test-planning documents. Priority: ⬇️ Low Merge Risk: 🟡 Moderate · up to Package checks may accept broken declarations or fail on valid ones. Correct the declaration checks before merging; restore focused coverage of the default snapshot budget. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to The normal snapshot limit and network-enforced size cap remain in place. One internal configuration edge case could interrupt snapshot delivery if a caller sets a limit above that cap; the only identified non-default use is a test with a smaller limit. Retained concerns

as a single declaration form so it captures the enum’s name, and add `let` to
the supported declaration keywords so exported let names are captured. Preserve
matching for the existing declaration forms.

associated checks in problems to recognize default imports such as import Foo
from "./target.js" and verify the target declaration exports default. Preserve
existing checks for braced imports.
- Line 74: Update the star re-export pattern to recognize both `export *` and
`export type *` declarations, so type-only star re-exports are recorded when
resolving type names while existing re-exports continue to work.

(Written by Opus 5.5) |
The regex parser missed default imports, `export type *`, `const enum`, and `let`, so the check could pass a broken default import or reject a valid one. Parse the AST with the parser deps.ts already uses, and skip asset imports like `./icon.svg?raw` that the bundler types. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

When an emitted declaration uses an inline type import, as js/net/src/wire.ts:88 does with import("./connection/established.ts").Established, Babel represents it as a nested TSImportType, but this loop examines only top-level statements and never records the target or name. Marking Established @internal would therefore leave a broken reference while this package check succeeds; traverse type nodes and add an inline-import regression case. (Written by GPT-5.6 Sol)

js/json"a compressed delta is gated on its encoded size" (~1.5 s idle, 4.3 s under load against a 5 s limit)xcompressed to 32 KB, so the delta never came near the cap. The test never reached the gate it names: gating on the plaintext instead passes it.snapshot.Encodertakes an@internalmaxGroupBytes(defaultGroup.MAX_GROUP_CACHE_BYTES). The test measures a small snapshot and delta, then sets a budget that fits the plaintext patch but not the encoded one. It runs in ~10 ms and fails when the gate measures plaintext.js/net/src/declarations.test.ts(5 s timeout)tsc --emitDeclarationOnly) insidebun test, about 3 s even on an idle machine.js/common/package.tsalready runs after every package'stscbuild, so the check runs there overdist/*.d.ts.just js checkbuilds every package, so every package gets this check now, not just@moq/net. The parser moved tojs/common/declarations.ts. It now resolves directory indexes (.,../catalog),.tsx, andexport default, whichsignals,hang, andmoq-boyneed. Its unit test,js/common/declarations.test.ts, runs in about 0.1 s and is wired intojust js test.

TheEMFILEcomes fromfs.inotify.max_user_instances(128 by default), a limit every process the user runs shares. A cap in.config/nextest.tomlwould not help, since most of the pressure comes from other processes.EMFILE, which failed the test. It now decides whether to skip from the listener's own watcher (its "hot reload disabled" log), so there is no second instance and no race.Reload::spawnnow does before the listener returns.
