Two additions to the virtual launcher's real-process mode: - Auto-restart watchdog. Replaces the poll-on-query PruneExitedProcesses with a per-process watcher thread (StartWatcher): when a real-launched app exits on its own -- not via a Kill*/Uninstall, which untrack it first -- it is dropped from the running list and, if its LaunchData has AutoRestart and the "Auto-restart after the app exits (watchdog)" toggle is on, relaunched after the Agent's 2 s delay. A watchdog generation counter cancels pending restarts when the pod goes dark (power off / reboot / reprovision / WipeApps); the console's KillAllApps leaves them pending, matching the real Agent's race. - postinstall.bat toggle. A "Run postinstall.bat after install" checkbox (above "Actually launch apps", off by default) makes an install execute a packaged postinstall.bat via cmd /c (waited up to 5 min) before deleting it, like the real service. Off, it is logged and removed unrun as before -- it runs package script code on the host. Both are opt-in from the vPOD window. Verified against the real LauncherRpcServer over a loopback socket: the watchdog test relaunches an exited ping.exe with a new PID and stops once toggled off; a crafted package's postinstall.bat runs (and is removed) only when enabled. Full differential suite 103/103. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
TeslaConsole.DiffTests — differential equivalence suite
Verifies that the reconstructed TeslaConsole.exe (built from the decompiled
source in this repo) behaves identically to the original reference binary in
original/TeslaConsole.exe.
How it works
The suite loads each assembly into its own child AppDomain
(DifferentialFixture) and drives it through a MarshalByRefObject proxy
(Invoker). This is why the project targets net48 — AppDomains are a .NET
Framework feature. The original is the 4.11.3.37076 baseline; the recovered
build is the modernized 4.11.4.x line (same TeslaConsole assembly name, an
intentionally newer version). Because the two versions differ, the public-member
comparison strips Version= stamps before diffing — it compares type/member names,
not assembly versions.
Each child domain is given a probe directory (the recovered build's output, which ships every dependency DLL) so the original — which is distributed without its proprietary dependencies — still resolves its references for metadata inspection.
What is compared
-
Public API surface (
PublicApiSurfaceTests) Every public type and public member (signature-for-signature) exposed by the original must also be exposed by the recovered build. Compiler-generated members and property/event accessor methods are excluded — the README at the repo root notes those legitimately differ between a decompilation and the lost sources. -
Recovered-only characterization (
CatalogTests,BTGoldenEggTests) Features that were added in the reconstruction have no counterpart in the original exe, so these run against the recovered build only:CatalogTests— the data-driven product catalog reproduces the exactLaunchDatathe old hardcoded code emitted.BTGoldenEggTests— the newTeslaConsole.BattleTechmission builder is diffed field-by-field against two golden eggs captured from the original consoles (BattleTech/cavern.egg,BattleTech/TESTARN.EGG). The comparison is per-section and order-independent (the pod parses eggs INI-style; the two golden eggs themselves disagree on field order). Font-rendered name-bitmap pixel rows are excluded, but TESTARN's ordinal art — identical to the RP-inherited rows — is compared byte-exactly. Also covers theEggFileMessagewire framing (NUL-delimited ASCII, 1000-byte chunks, byte-exact reassembly), role-block de-duplication, the No Return mode (samescenario=freeforall, different role), and the shippedBattleTech\BTConfig.xmlcatalog contents.
-
Behavioral output (
BehavioralEquivalenceTests) The same deterministic, dependency-free methods are invoked in both assemblies over a battery of inputs and the results must match byte-for-byte:RPStrings.GetTimeString(mm:ss formatting + 0.5 s rounding)HostTypeHelper.Parse(...).ToString()(incl. invalid-input exceptions)PlasmaBitmaps.ConvertBitmap(1-bpp packing of a known pixel pattern)PlasmaBitmaps.GenerateString(full GDI text → 1-bpp plasma pipeline)RPMap/RPVehicleXML parsingSiteManagementwell-known application GUID constantsTuple.Create<,>generic factory
A negative-control test (
Harness_Distinguishes_Different_Outputs) proves the harness can actually see a difference, so a green run is never vacuous.
The project also carries two byte-compatibility guards — not original-vs-recovered comparisons, but checks that the modernized protocol/crypto stays compatible with the original binaries:
PodRpcProtocolTests— round-trips the framed-JSON RPC (Contract/PodRpcProtocol.cs) in-process: every request/response shape encodes and decodes back to the same values.SecureConfigCompatTests— asserts the source-builtOFBCryptoStreamproduces byte-identical ciphertext to the originalTeslaSecureConfiguration.dll, so the pod provisioning handshake stays wire-compatible.
Running
dotnet test tests/TeslaConsole.DiffTests/TeslaConsole.DiffTests.csproj
A project reference builds the reconstruction first, and the suite always tests
the most recently built bin/{Debug,Release}/net48/TeslaConsole.exe.
Scope / limitations
This compares deterministic logic. It deliberately does not drive the WinForms UI, the pod networking, secure-configuration, or hardware-facing code — those require the live console, its pods, and the proprietary services, and are not reproducible in a unit test. The API-surface test still asserts those types exist with matching signatures even though their behavior isn't exercised.
