Summary

AGENTS.md says error and warning classes live in lib/errors/ whatever raises them, but sixteen did not: ten sat beside the plugin that raised them, and six were declared inline inside one. All sixteen move; each raising plugin stays where it is and imports the class.

Doing that made the second commit worth having. A moved class needed one registerLegacyRequest call per request it had been written under, so 102 files repeated the class name and the name argument two or three times over — 119 call sites. makeSerializable now takes an array instead, current request first and the legacy ones after, which leaves one such call site in the tree. Each array marks its legacy entries TODO in the next major release, so the cleanup is one grep. Nothing about the wire format moves: the first entry registers exactly as before and the rest go to registerLegacyRequest underneath.

What kind of change does this PR introduce?

refactor — no behavior change; the only public-surface move is util.makeSerializable also accepting an array.

Did you add tests for your changes?

No new ones — the existing suites are the check here. internalSerializables.js regenerates byte-identical (262 entries) and dumping the serializer maps before and after shows the 282 read keys and 163 registrations unchanged, but for the two deprecation warnings that now carry the name their older requests always had.

Does this PR introduce a breaking change?

No — registerLegacyRequest stays exported and still works, and every historical request stays readable.

If relevant, what needs to be documented once your changes are merged or what have you already documented?

That makeSerializable takes several requests, current one first, wherever writing a custom dependency is documented; AGENTS.md says so already.

Use of AI

Claude Code was used to find the misplaced classes, make both changes, and verify them: yarn lint, find-deep-imports:check, the cache and config suites, and a before/after dump of the serializer maps to show the registrations are unchanged.

Summary by CodeRabbit

  • Bug Fixes

    • Preserved compatibility with existing cache packs after internal modules were reorganized, so cached builds can still be restored.
    • Added coverage for warnings about imports that differ only by letter case.
  • Refactor

    • Consolidated warning and error handling while keeping existing diagnostics and behavior intact.

AGENTS.md says error and warning classes live in `lib/errors/` whatever
raises them, but sixteen did not: ten sat beside the plugin that raised
them, and six were declared inline inside one.

Ten files move as they are -- `ESMLinkingError`, `FalseIIFEUmdWarning`,
`MinMaxSizeWarning`, the four `SizeLimitsPlugin` warnings,
`DuplicatePackagesWarning`, `UnsupportedWebAssemblyFeatureError` and
`WebAssemblyInInitialChunkError`.

Six are extracted from the plugin that declared them: `NoModeWarning`,
`DeprecatedOptionWarning`, `CaseSensitiveModulesWarning` (with the two
helpers only it reads), `DllManifestError`,
`RequireIncludeDeprecationWarning` and `SystemImportDeprecationWarning`.
Each raising plugin stays where it is and imports the class.

The last two are serializable, so each registers under its new request
and keeps both historical requests open with `registerLegacyRequest` --
they had already moved once -- or a pre-move cache pack stops loading.
`SystemPlugin.SystemImportDeprecationWarning` stays as it was.

No re-export is owed: `find-deep-imports:check` records no published
package importing any of the sixteen paths. `types.d.ts` regenerates
byte-identical, and `WebAssemblyInInitialChunkError` gains a marker, as
it is raised only from `lib/wasm-sync/` and no longer sits there.
…s too

A moved class needed a `registerLegacyRequest` call per request it had
been written under, so 102 files repeated the class name and the `name`
argument two or three times over -- 119 call sites in all.

`makeSerializable` now takes an array instead: the first entry is the
request the class is written under, the rest are the ones it stays
readable under. It registers the first exactly as before and hands the
rest to `registerLegacyRequest`, so nothing about the wire format moves.

Each array marks the legacy entries `TODO in the next major release`, so
the whole cleanup is one grep, and the reason a given request exists
stays next to it where it was already written down.

`registerLegacyRequest` stays exported and is still used once, where the
array cannot say it: `ModuleExternalInitFragment` registers with
`register` and a serializer of its own. The two deprecation warnings
moved to `lib/errors/` in the previous commit now carry the `name` their
older requests always had, rather than registering under none.

`generate-internal-serializables.js` read only the first request of a
call, so it now reads them all; it regenerates `internalSerializables.js`
byte-identical, all 262 entries. Dumping the serializer maps before and
after shows the 282 read keys and 163 registrations unchanged but for
those two names.

📝 Walkthrough

Walkthrough

The change adds ordered legacy request support to makeSerializable and updates serialization registrations across webpack modules. It also moves warning and error classes into shared error modules, updates their callers and registry entries, and adds a case-sensitive module warning test.

Changes

Serialization and error handling

Layer / File(s) Summary
Multi-request serialization contract
lib/util/makeSerializable.js, tooling/generate-internal-serializables.js, AGENTS.md, .changeset/*
makeSerializable accepts a request string or an ordered array. The generator extracts all requests in the array. The guide and Changeset describe the current-first order.
Legacy serialization registrations
lib/asset/*, lib/context/*, lib/dependencies/*, lib/dll/*, lib/entry/*, lib/errors/*, lib/externals/*, lib/fs/*, lib/graph/*, lib/javascript/*, lib/json/*, lib/module/*, lib/node/*, lib/optimize/*, lib/provide/*, lib/template/*, lib/wasm/*
Serializable classes now pass their existing and legacy request identifiers to makeSerializable.
Shared warning and error classes
lib/errors/*, lib/diagnostics/*, lib/dependencies/commonjs/*, lib/dependencies/system/*, lib/dll/*, lib/util/internalSerializables.js, lib/library/*, lib/optimize/*, lib/performance/*, lib/wasm-sync/*, test/unitCases/Errors.unittest.js
Warning and error classes move to lib/errors, and callers and internal registry entries use those modules. The unit test checks the case-sensitive module warning when the filesystem supports distinct filenames.

Priority: ⬇️ Low

Merge Risk: 🟡 Moderate · up to 8f951

Supported Node 10 users cannot run the affected lint and fix scripts. Replace the generator call before merging, or explicitly accept that workflow limitation.

Review details

Systems and components

  • observed — lib (service) was modified; 131 changed files map to changed impact.
  • observed — AGENTS.md (service) was modified; 1 changed file maps to changed impact.
  • observed — test (service) was modified; 1 changed file maps to changed impact.
  • observed — tooling (service) was modified; 1 changed file maps to changed impact.

Before / after behavior

  • observed — Modified behavior in AGENTS.md: The Architecture entry replaces the general registerLegacyRequest guidance with an array of prior serialization requests, keeping the current request first; it notes registerLegacyRequest is only needed when the array cannot represent a registration or a prior request with a different name.
  • observed — Modified behavior in AGENTS.md: The file-move checklist now says to retain old serialization requests in an array after the current request, using registerLegacyRequest only for registrations or serializers the array cannot express.
  • observed — Modified behavior in AGENTS.md: The diagnostics guidance replaces the claim that nothing in lib/performance/ registers with the specific rule that warnings created after seal and pushed to compilation.warnings are not packed.
  • observed — Modified behavior in lib/asset/RawDataUrlModule.js: Removed the registerLegacyRequest import; legacy serialization compatibility is now declared in the makeSerializable registration.

Read Changed, test untouched first: the test is byte-identical on both sides, so webpack generated the difference. Changed, test edited moved partly because the test did — Test edit is how many bytes the test gained, and a bundle that grew by less is not a regression. New and Deleted are whole files, not deltas — a new asset was created, not grown, so it reads gray (⚪ added) — and adding tests cannot bury a real change. Gzip decides, because that is what users download; raw is the tiebreak, and brotli and zstd are per asset below.

No asset that both runs emit changed size — everything below is new or deleted.

Replace matchAll to support the declared Node range.

package.json declares Node >=10.13.0, and the generator runs directly in the lint:special, fix:special, and fix:serializables scripts. Node 10.13 does not provide String.prototype.matchAll, so this call can throw before generation completes. Use a global RegExp.exec loop.

Suggested fix
-const extractWebpackLibRequests = (call) =>
-	[...call.matchAll(/["'`](webpack\/lib\/[^"'`]+)["'`]/g)].map(
-		(match) => match[1]
-	);
+const extractWebpackLibRequests = (call) => {

The existing case has it backwards by necessity: it runs only where
`FILE.js` resolves to the committed `file.js`, so the warning is
exercised on a case-insensitive filesystem and the Linux branch asserts
the module-not-found error instead. Every coverage uploader is
ubuntu-latest, so `CaseSensitiveModulesWarning` read 21% -- its message
builder never ran in a run that reported.

Write the colliding pair to a temporary directory instead, which a
checkout cannot hold, and assert the warning a real build emits. Where
the two names are one file the case above already covers it, so the test
returns. Statements, lines and functions go 21% -> 100%.

Folding into `007-export-module-type-and-target-plugins` took an entry
that was already 189 characters to 244, the longest pending one. That
entry belongs to the change that exposed `util.makeSerializable`; this
PR widens it, which is its own line.

The new entry is 69 characters, inside the 80 `.coderabbit.yaml` asks
for, and 007 goes back to what main has.

- Add `optimization.minimize.css.dropOverriddenDeclarations`, dropping a declaration a later one overrides where no target is named. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;22175](webpack/webpack#22175))
