Validate the original question before adding immutable Evidence scope, and preserve each result's supporting link through CLI and MCP producers. Apply the shared policy to derived investigations, managed comparisons and verification, composed workflow residuals, and process-capture residuals. This prevents registry conflicts and silent loss of later result links. Keep explicit creation/update semantics and exact Evidence replays intact. Cover all affected producer families with public MCP regressions, preserve snapshot provenance distinctions, and retain blank-question/error handling. Remove the superseded single-result call-path test.

Retain directory metadata and sibling observations, distinguish known identity replacements, and keep cancellation and unexpected I/O failures terminal. Reuse admitted root metadata and test cancellation by descriptor state rather than a count of named lookups. Adapt the symlink race handling proposed in #4587 at fae4e25539969671c82a4d56cfb0b50761b833a3. Closes #4575 BREAKING CHANGE: Filesystem enumeration omission reasons now also include entry_unavailable and identity_changed.

Give an admitted root's enumeration failure its own typed field, use it for unresolved symlink coverage, and project it as a graph limitation instead of an invalid dot-path child entry. Keep admission, cancellation and cleanup failures distinct. Closes #5135 Closes #5136 BREAKING CHANGE: Partial reference-source reader results report failed root enumeration in rootFailure instead of a failed directory child at path ".". Historical source graphs preserve the root failure as a top-level limitation. --- docs/cli.md | 6 + .../ReferenceSourceImportEntries.ts | 4 + src/reference/ReferenceSourceReader.test.ts | 27 +++ src/reference/ReferenceSourceReader.ts | 21 +- src/reference/ReferenceSourceReaderEntries.ts | 70 +++--- src/reference/ReferenceSourceReaderTypes.ts | 8 + .../referenceSourceCleanupOwnership.test.ts | 5 +- .../referenceSourceSymlinkRace.test.ts | 213 ++++++++++++++++++ 8 files changed, 312 insertions(+), 42 deletions(-) create mode 100644 tests/process-global/referenceSourceSymlinkRace.test.ts diff --git a/docs/cli.md b/docs/cli.md index c0f8eefff4..cad2255d91 100644 --- a/docs/cli.md +++ b/docs/cli.md @@ -286,6 +286,12 @@ reported separately as configured-secret exclusions.

Completed file observations cannot authorize launch for a cancelled request. Preserve exact caller reasons in the shared capture cancellation constructor and its admission, exit and finalization consumers instead of reconstructing them downstream. Exercise real executable reads and closes through the capture API with a throwing PTY sentinel at five schedules. Retain a real completed Node capture and its cleanup facts when the final progress callback cancels the request. Strengthen existing metadata and baseline cancellation controls.

Resolve the native removal argument in current registration order, then let EventEmitter own mutation, getter timing and removal meta-events. Leave registrations unwrapped with explicit observation gaps when methods or receivers do not support that ownership model.

Bind originating capture errors and typed retry aggregates to those owners while preserving primary failures and completed observations. Keep those bindings through MCP close and compose mixed session/process cleanup failures. Start both close operations even when a child throws a typed failure synchronously.

Scan JSON whitespace within its declared extent and decode budget without retaining the whitespace prefix. Keep prefix storage bounded independently of stream chunk ownership. Fill fixed ASAR prefixes and DMG trailers across short reads, preserve cancellation through admission and stream EOF, and retain existing cleanup ownership. Cover public CLI/MCP selection, root/nested inventory, malformed JSON whitespace and padding, limits, native/XML consumers and descriptor faults. Validation: 24 focused files / 170 tests; full check; docs check; test discovery. Official inert ASAR fixtures and controlled descriptor faults were exercised; real Electron execution, Windows and natural OS short-read frequency remain unverified. Equivalent compact CLI tasks returned identical results and reply token estimates; repeated timings do not establish a speedup.

Carry successful rows, thread children and bounded diagnostics together so one failed sibling cannot erase readable peers. Retain root initialization failures and validate ps-discovered Linux candidates through stable procfs identity brackets. Await issued reads during shutdown, retain completed rows and report an unfinished pass through the existing sampling failure/diagnostic contract. Derive partial coverage at its owner and preserve actual read errors when shutdown also interrupts observation. Keep the public capture schema unchanged and verify it with the previous strict capture reader. Update directly affected coverage consumers and regression fixtures, including identity contradictions, mixed outcomes, late failures, cleanup, cancellation, process-only comparison unknowns and converted MCP schemas. Validation: 12 focused files / 123 tests; full check; docs check (5 tests); test discovery (1,635 files). Real macOS CLI/MCP controls exercised source-owned PTY targets. Linux permission behavior uses deterministic boundary fixtures; real Linux and Windows qualification remain unavailable. Completed CLI cost comparisons do not establish a speedup.

If cancellation arrives during a native Frida call, REA waits for that call to return, then closes any session it created and returns the observed session as a partial observation. A cancelled script load on an existing session releases only its new script before queued operations can run; the session and previously loaded scripts remain available. If cancellation is observed when the native call returns, partial Evidence retains the source identity and captured messages even if that call rejects, including messages emitted during awaited cleanup. The caller's cancellation reason remains primary and a native rejection is retained as a sanitized diagnostic. A failure already observed before cleanup stays primary if cancellation arrives during cleanup. The cancellation cutoff is REA's observation of native completion, rather than a claim about unobservable native event order. `script_id` is REA's load-attempt identity. When creation rejects without returning a handle, `script_cleanup: "no_handle"` means REA acquired no handle to unload; it does not prove that the engine performed no work. Once the provider commits a successful load, later request cancellation does not unload that script; use `unload_frida_script` to release it. If script cleanup fails, the script remains owned and a paused target cannot resume until the pending instrumentation is released. Queued script loads, resumes, and unloads check cancellation before dispatching native effects. Cancellation Evidence separately reports whether a target resume was observed, whether instrumentation cleanup completed, and that final target liveness remains unknown. REA does not kill the target. Remote discovery retains its observations and reports a separate cleanup error if the temporary connection cannot be removed. The [Frida Core API](https://frida.re/docs/frida-core-api/) documents device management, sessions, and script loading; the [JavaScript API](https://frida.re/docs/javascript-api/) documents target-side instrumentation. [Luma](https://luma.frida.re/) is Frida's standalone GUI; REA does not automate or control it. `npm run verify:frida` requires a Linux host with the optional Frida binding and uses a short-lived local Node.js fixture created by the verifier. Add `-- --address HOST:PORT --pid PID` to run the separate remote attach lane against a caller-selected target. Mock tests do not establish real device/server compatibility. diff --git a/src/application/frida/FridaInstrumentationManager.test.ts b/src/application/frida/FridaInstrumentationManager.test.ts index 86733cf594..030e8f9420 100644 --- a/src/application/frida/FridaInstrumentationManager.test.ts +++ b/src/application/frida/FridaInstrumentationManager.test.ts @@ -1,4 +1,5 @@ -import { describe, expect, it } from "vitest"; +import { describe, expect, it, onTestFinished } from "vitest"; +import { createDeferred } from "../../../tests/fixtures/binarySession.js"; import type { Device, @@ -9,7 +10,11 @@ import type { Session, Signal, } from "frida"; -import { AnalysisInputError } from "../../domain/analysisErrorCore.js"; +import { FridaScriptLoadCancelledError } from "./FridaInstrumentationPort.js"; +import { + AnalysisCapabilityUnavailableError, + AnalysisInputError, +} from "../../domain/analysisErrorCore.js"; import { FridaInstrumentationManager } from "../../frida/FridaInstrumentationManager.js"; const signal = void>() => { @@ -1345,3 +1350,96 @@ it("names the unknown session or script ID it rejects", async () => { }); await manager.closeAll(); }); + +it.each([false, true])( + "retains messages emitted during cancelled script cleanup after native rejection=%s", + async (rejectNative) => { + const { bindings, manager, started } = await startLocalAttachedSession(); + onTestFinished(() => manager.closeAll()); + if (!started.ok) throw started.error; + const session = bindings.device.session; + const entered = createDeferred(); + const held = createDeferred(); + onTestFinished(() => held.resolve()); + session.onScriptLoadStarted = entered.resolve; + session.scriptLoadGate = held.promise; + const nativeFailure = new Error("native load failed"); + if (rejectNative) session.nextLoadFailure = nativeFailure; + const controller = new AbortController(); + const reason = new Error("cancel before native completion"); + const loading = manager.loadScript( + started.value.sessionId, + { sourceKind: "inline", source: "send('marker')" }, + controller.signal, + ); + await entered.promise; + const script = session.scripts[0]; + if (script === undefined) throw new Error("Missing admitted script"); + const unload = script.unload.bind(script); + script.unload = async () => { + script.message.emit({ type: "send", payload: "during cleanup" }, null); + script.message.emit( + { type: "send", description: "x".repeat(40_000) }, + null, + ); + await unload(); + }; + controller.abort(reason); + held.resolve(); + const loaded = await loading; + if (loaded.ok) throw new Error("Cancelled load succeeded"); + expect(loaded.error).toBeInstanceOf(FridaScriptLoadCancelledError); + if (!(loaded.error instanceof FridaScriptLoadCancelledError)) + throw loaded.error; + expect(loaded.error.cause).toBe(reason); + expect(loaded.error.script.messages).toContainEqual( + expect.objectContaining({ payload: "during cleanup" }), + ); + expect(loaded.error.script.messagesTruncated).toBe(true); + expect(loaded.error.diagnostics).toEqual( + rejectNative ?

Exclude identifier prefixes, pre-checkpoint context, and unconfirmed tails; preserve invalid UTF-8 and directional truncation facts. Make confirmed OOME observations authoritative for projection. Retained raw prefixes cannot establish an OOME, and unrelated output cannot supply its resource kind or recovery advice. Incomplete no-OOME output preserves the primary error and explains uncertainty. Current checkpoint coverage remains separate from historical budget loss. Adapt the retention approach from #4774 with independently reproduced scanner and projection counterexamples corrected before integration. Validation: 268 focused tests, npm run check, npm run docs:check, and test discovery (1639 files exactly once) pass. Controlled Node pipes/socket and fake Ghidra JVM only; real Ghidra and native Linux/Windows behavior are unverified.

CLI and MCP now consume that result directly, including retained observations when final CLI cleanup fails. Remove the duplicate adapter projections and preserve provider failures, caller-selected identifiers, process records and cleanup diagnostics. Validated with 103 focused tests, npm run check and docs:check. Real local Frida 17.23.2 discovery on macOS arm64 returned the same three devices through the compiled CLI and production stdio MCP; both now pass the advertised schema. Remote endpoints and native Linux/Windows unverified.

Frida now retains the correct bounded prefix and reports truncation in script results and subsequent session Evidence. Move the existing exact managed string counter into the domain layer and use it for Frida, managed projections and Ghidra inline PDB caveats. Remove the superseded counters while keeping Ghidra's bounded length guards and NativeAOT's distinct raw-byte admission before string allocation. Validated with 296 focused tests, check, docs and exact test discovery. The Unicode oracle checks every UTF-16 code unit and adjacent fragments against native JSON encoding.

This includes the JavaScript runtime owner and removes the separate four-provider list. Preserve all load failures in server injection and keep shared providers caller-owned across individual server closure. Retain failed close hooks for retry while removing peers whose cleanup completed. Validated with 19 focused lifecycle/isolation checks and a final rerun of the new boundary regression, check, docs and exact test discovery. The runner test uses real idle providers with controlled SDK/shutdown handles and a close rejection; active Inspector resource consequences, native Linux/Windows and end-to-end stdio shutdown remain unverified.

Reuse the valid ASAR Pickle fixture and preserve truncated-container rejection. * fix(tests): isolate runtime faults and own CLI subprocesses Keep the runtime provider mock in the isolated project after reused CLI graphs exposed lost fault injection. Use the existing owned CLI fixture for Inspector parity and update command checks, retain caller environment choices, and require the removed alias to fail with COMMAND_NOT_FOUND. Keep current test deadlines and production behavior. * fix(process): retain executable handles through read cancellation Use the existing borrowed descriptor reader so stream cancellation cannot invalidate a handle owned by capture. Preserve the exact cancellation and permit immediate scope reuse after cleanup. Reproduce the native-stream failure with actual file IO and retain completed/failed-close controls. Synchronize runtime cancellation and backwards-clock injection with observed running progress. The corrected clock oracle now rejects a Date.now-based deadline under controlled rollback; keep test deadlines and narrow host cleanup checks unchanged. * test(process): observe prelaunch cancellation at descriptor reads * fix(process): retain read failures alongside observed cancellation * fix(flutter): advertise portable Unicode ABI selectors --- docs/testing.md | 2 +- src/domain/flutter/flutterBuildAnalysis.ts | 26 ++-- .../capture/ProcessCaptureLifecycle.ts | 13 +- src/process/capture/ProcessCaptureRead.ts | 14 +- .../directAnalysisSnapshotReplay.test.ts | 2 +- .../boundary/filesystem/zipDetection.test.ts | 32 ++--- tests/boundary/mcp/flutterMcp.test.ts | 13 +- .../process/processCaptureLifecycle.test.ts | 72 ++++++++-- .../process/processCaptureProgress.test.ts | 26 ++-- .../processSnapshotHandleOwnership.test.ts | 3 + .../process/selectedExecutableCleanup.test.ts | 135 ++++++++++++++++++ ...systemSnapshotFallbackCancellation.test.ts | 26 +++- .../filesystemSnapshotRaces.test.ts | 120 +++++++--------- .../javascriptRuntimeObservationCli.test.ts | 106 ++++++-------- .../processPrelaunchCancellation.test.ts | 18 ++- .../processSnapshotCleanupMcp.test.ts | 19 ++- .../process-global/updateMaintenance.test.ts | 30 ++-- 17 files changed, 431 insertions(+), 226 deletions(-) rename tests/{boundary/cli => process-global}/javascriptRuntimeObservationCli.test.ts (64%) rename tests/{boundary/mcp => process-global}/processSnapshotCleanupMcp.test.ts (89%) diff --git a/docs/testing.md b/docs/testing.md index 6a0b7984a9..334024cc1a 100644 --- a/docs/testing.md +++ b/docs/testing.md @@ -92,7 +92,7 @@ without serial scheduling.

Bind token observations to native generations and retain related generations and unresolved identity lookups across table omissions, reparenting and process-group changes without treating PID hints as authority. Use native effective UID facts for withholding decisions, corroborate Linux procfs absence, and share the Linux stat parser with sampling and debugger identity checks. Signal only after current token and group revalidation. Complete swept cleanup across all groups with one bounded final family check; retain unresolved owners and successful-peer completion across retries. Validation: npm run check, docs:check and test discovery passed. Focused ownership/consumer coverage totals 513 passed and 1 skipped across 35 files, including the corrected Electron cancellation test rerun independently. Darwin helper compilation, real owned Node child cleanup, CLI/MCP capture and retained cleanup retries ran. Real Electron applications, native Linux races/PID reuse and Windows cleanup were not qualified. The original Linux reports remain open for that work.

Preserve HAR canonical pad bits and validate before allocation. Replace repeated alphabet quartets in canonical schemas with separate alphabet, padding and fixed-width length assertions. Cover near-32MiB encodings under ordinary, Unicode and Unicode-set modes, plus complete 4MiB CLI and MCP retained-evidence export workflows.
