📄 Description

Summary

Ignore XML processing instructions between plist/container members. Previously a legal <?rea ignored?> could reach value decoding, fail, and prevent an app's Info.plist from resolving its executable.

Fixes #4964.

Problem and expected behavior

<plist><?rea ignored?><string>demo</string></plist> should decode as "demo", following Apple's CFPropertyList member reader. The shared decoder instead interpreted the instruction's target as a plist tag.

Change and scope

Exclude PROCESSING_INSTRUCTION_NODE at the existing members() boundary. Add container regressions and filesystem-backed app-resolution checks for macOS-style and flat iOS-style directory layouts on Windows. Scalar content rules and XML well-formedness checks remain unchanged. This is a routine compatibility correction within existing static reads; no separate maintainer scope decision is required.

Contract and boundary impact

  • Semantic owner: shared XML plist container-member decoding.

  • Contribution scope: existing local static analysis; no new provider or execution authority.

  • CLI/MCP schemas, generated catalogs, package metadata, and installation: unchanged.

  • Evidence: valid instruction nodes no longer masquerade as data or prevent decoding; source bytes and provenance handling are unchanged.

  • Target effects: existing file reads only; no target execution, mutation, or new persistence.

  • Read existing files or captured data.

  • Launch or attach to a process.

  • Inject instrumentation or run scripts/code.

  • Change process memory, registers, files, or configuration.

  • Contact network services.

  • Recover protected code or work around protections.

  • Documentation or usability only; no target interaction.

  • Not sure yet; investigation or maintainer guidance needed.

Evidence and regression coverage

  • Before the correction: 5 new failures and 35 passing controls on source 6b180783ed04ebc87548c8385c80e05725804c47.

  • After the correction: 107 tests passed across the shared XML decoder, key handling, app resolution, and native plist result parser.

  • The regressions cover plist/array/dict positions, instructions named like plist tags, dictionary key/value boundaries, malformed instructions, and real unsupported elements.

  • Default-filesystem app resolution succeeds for both authored bundle layouts. Fixture program files are inert text and were never executed.

  • Python 3.12.14 plistlib independently accepts the matching valid XML fixtures. Apple's source is a reference comparison, not an executed Apple runtime.

  • Observed, derived, and inferred claims remain distinguishable.

  • Artifact identity, source provenance, and failed attempts remain preserved.

  • Unsupported, incomplete, unavailable, or uncertain outcomes remain visible.

Review follow-up

In response to @XinwangTao's boundary-coverage suggestion, d34d704 adds four cases covering an XML declaration with ordinary processing instructions before/after the root, literal instruction text in CDATA/escaped content, and existing incomplete integer handling with PI/comment markup. These protect existing boundary behavior; no further production change was needed. Strict malformed-XML rejection is unchanged.

Validation performed

Windows x64, Node 24.18.0, npm 11.16.0.

  • npm run test:local -- src/domain/propertyListXml.test.ts src/application/AppBundleExecutable.test.ts src/domain/propertyListKeys.test.ts src/native/parsers/plist.test.ts — 107 passed.
  • npm run verify:test-discovery — all 1,578 test files discovered exactly once.
  • npm run check:fast — typecheck and lint passed.
  • npm run format:check — all 4,017 matched files passed.
  • npm run metadata:check — passed.
  • npm run verify:architecture-guards — passed across 1,506 source files.
  • git diff --check — passed.
  • npm run check — could not start the Windows artifact-lock wrapper (missing matching native addon).
  • npm run knip — one unresolved existing package import, #javascript-analysis-worker, whose target is the unbuilt dist/composition/javascriptAnalysisWorkerProcess.js. No imports in the production change were added or modified.

Compatibility, safety, and release

No new dependencies, migrations, tool schemas, or target effects. Actual macOS/iOS execution and plutil were not tested. Full npm run check could not start its artifact-lock wrapper because the source checkout lacks the matching 6.6.0 Windows native addon; that exact npm version was unavailable when checked. Source-level checks are recorded separately. No performance improvement or production prevalence is claimed.
