From 067419c3b9b97a9dbefccc6868d0314e9c40e289 Mon Sep 17 00:00:00 2001 From: "ren.ji" Date: Thu, 1 Oct 2026 14:54:28 +0800 Subject: [PATCH 01/16] racket: port core runtime and the diagnostics stack (phases 1-2 core) Core runtime: frozen wire-contract records with typed camelCase serializers, evidence pipeline with bounded stores and per-target context rings, the runtime state machine (target-first mutation gates with rollback, first-cause-wins cancellation, wall-clock deadline rejection of late successes, bounded history, drain), and the target-oriented facade (power/serial/flash/diagnostics operations, preflight, real-ECU readiness). Diagnostics: ISO 15765-2 codec and endpoint over an in-process simulated CAN bus with per-port pump threads, the ISO 14229 UDS client (P2/P2* timing, NRC 0x78 pending), the behavioral simulated ECU (sessions with S3 timeout, security access attempt counting, DID read/write, erase/verify routines, RequestDownload/TransferData/Exit block sequencing), the transport-independent flash engine (CRC32 verify, audited steps) and the simulator bench (power/serial/flash sharing virtual board state). 42 ported/contract tests green locally; port bugs found by the port itself: escaped-string corruption in tolerant JSON reading (regression test added), '() used as empty-queue marker (truthy in Racket), left-shifts where C# encoders right-shift. --- racket/benchpilot/core/bench-runtime.rkt | 1125 +++++++++++++++++ racket/benchpilot/core/contracts.rkt | 539 ++++++++ racket/benchpilot/core/evidence.rkt | 367 ++++++ racket/benchpilot/core/runtime-state.rkt | 632 +++++++++ .../diagnostics/channels/sim-uds-channel.rkt | 706 +++++++++++ .../benchpilot/diagnostics/flash/engine.rkt | 293 +++++ .../diagnostics/flash/workflow-test.rkt | 109 ++ .../diagnostics/isotp/codec-test.rkt | 68 + racket/benchpilot/diagnostics/isotp/codec.rkt | 165 +++ .../benchpilot/diagnostics/isotp/endpoint.rkt | 277 ++++ .../transport/simulated-can-bus.rkt | 126 ++ .../benchpilot/diagnostics/uds/protocol.rkt | 265 ++++ .../benchpilot/simulator/simulated-bench.rkt | 293 +++++ racket/info.rkt | 4 +- 14 files changed, 4968 insertions(+), 1 deletion(-) create mode 100644 racket/benchpilot/core/bench-runtime.rkt create mode 100644 racket/benchpilot/core/contracts.rkt create mode 100644 racket/benchpilot/core/evidence.rkt create mode 100644 racket/benchpilot/core/runtime-state.rkt create mode 100644 racket/benchpilot/diagnostics/channels/sim-uds-channel.rkt create mode 100644 racket/benchpilot/diagnostics/flash/engine.rkt create mode 100644 racket/benchpilot/diagnostics/flash/workflow-test.rkt create mode 100644 racket/benchpilot/diagnostics/isotp/codec-test.rkt create mode 100644 racket/benchpilot/diagnostics/isotp/codec.rkt create mode 100644 racket/benchpilot/diagnostics/isotp/endpoint.rkt create mode 100644 racket/benchpilot/diagnostics/transport/simulated-can-bus.rkt create mode 100644 racket/benchpilot/diagnostics/uds/protocol.rkt create mode 100644 racket/benchpilot/simulator/simulated-bench.rkt diff --git a/racket/benchpilot/core/bench-runtime.rkt b/racket/benchpilot/core/bench-runtime.rkt new file mode 100644 index 0000000..f485228 --- /dev/null +++ b/racket/benchpilot/core/bench-runtime.rkt @@ -0,0 +1,1125 @@ +#lang racket/base + +;; Target-oriented runtime facade, port of BenchTarget.cs, +;; BenchTargetDiagnostics.cs, BenchPreflight.cs, BenchResourceRegistry.cs, +;; ResourceDrivers.cs, BenchReadiness.cs and the Core abstractions. +;; +;; This is the single safety/validation choke point: callers request semantic +;; operations on targets and never see drivers directly. + +(require json + racket/contract + racket/file + racket/format + racket/generic + racket/list + racket/string) + +(require "contracts.rkt" + "evidence.rkt" + "profile.rkt" + "readiness.rkt" + "runtime-state.rkt") + +;; driver generics (Core abstractions) +(provide gen:resource-health-check + gen:power-supply + gen:serial-channel + gen:flash-target + gen:diag-channel + check-health + power-supply?

End-to-end through real HTTP: doctor, validate, power on, flash, serial wait, UDS DID read, power check, history, power off, shutdown — all green through the CLI against the daemon. Port-side findings: hasheq never matches dynamically-built string keys (equal?-hash the header table), Racket 0/1 integers are truthy like everything else, case only matches symbol datums, and #rx lacks \d and {n} (use #px). 44 unit tests + the CLI/daemon flow green locally. --- racket/benchpilot/client/cli.rkt | 866 ++++++++++++++++++ racket/benchpilot/core/bench-runtime.rkt | 54 +- racket/benchpilot/core/contracts.rkt | 1 - racket/benchpilot/core/profile.rkt | 10 +- racket/benchpilot/core/readiness-test.rkt | 22 +- racket/benchpilot/core/readiness.rkt | 5 +- racket/benchpilot/core/runtime-state.rkt | 1 + .../diagnostics/channels/sim-uds-channel.rkt | 2 + racket/benchpilot/protocol/local-auth.rkt | 49 + racket/benchpilot/runtime-host/daemon.rkt | 545 +++++++++++ racket/benchpilot/runtime-host/http.rkt | 252 +++++ .../benchpilot/simulator/simulated-bench.rkt | 2 +- 12 files changed, 1770 insertions(+), 39 deletions(-) create mode 100644 racket/benchpilot/client/cli.rkt create mode 100644 racket/benchpilot/protocol/local-auth.rkt create mode 100644 racket/benchpilot/runtime-host/daemon.rkt create mode 100644 racket/benchpilot/runtime-host/http.rkt diff --git a/racket/benchpilot/client/cli.rkt b/racket/benchpilot/client/cli.rkt new file mode 100644 index 0000000..cdd9feb --- /dev/null +++ b/racket/benchpilot/client/cli.rkt @@ -0,0 +1,866 @@ +#lang racket/base + +;; BenchClient.cs + RuntimeAutoStart.cs + Program.cs (CLI) port: the +;; benchpilot CLI — a thin JSON client of the resident runtime with the +;; stable exit-code contract, one-retry autostart and the doctor check. + +(require json + racket/format + racket/list + racket/port + racket/set + racket/string + racket/tcp) + +(require benchpilot/core/contracts + benchpilot/core/profile + racket/file + racket/path + benchpilot/diagnostics/flash/engine + benchpilot/diagnostics/uds/protocol + benchpilot/protocol/local-auth) + +(provide bench-client-run! + parse-cli-args + last-printed-box) + +;; ---------------------------------------------------------------------------- +;; Errors: code → exit code, mirroring the C# BenchClientException switch. +;; ---------------------------------------------------------------------------- + +(struct bench-client-error + (code message status-code operation-id busy-scope busy-id deadline-ms deadline-at-utc) + #:transparent) + +(define (error-exit-code e) + (case (bench-client-error-code e) + [(busy) 5] + [(deadline_exceeded) 6] + [(cancelled) 1] + [(runtime_state) 4] + [(unauthorized) 4] + [else + (case (bench-client-error-status-code e) + [(400) 2] + [(404) 3] + [else 1])])) + +(define (validation-error message) + (exn:benchpilot:validation message (current-continuation-marks))) + +(define (raise-validation message) + (raise (validation-error message))) + +;; ---------------------------------------------------------------------------- +;; CLI arguments (CliArguments): long options, `--opt value` or `--opt=value`, +;; and the flag set.

charset=UTF-8 Content-Transfer-Encoding: 8bit - scripts/build-dist.sh: per-RID distributions — Windows ships three embed-dlls single-file executables, Unix a full raco distribution tree (bin/ + lib/); committed launcher entries under packaging/launchers/ so the packaged CLI/daemon/MCP behave exactly like the E2E-tested wrappers - install.sh installs the tree under ~/.benchpilot/lib/benchpilot/ and writes thin bin wrappers; the self-updater follows wrappers back to the real launchers and swaps them in place - Debian package carries the distribution tree under /opt/benchpilot with /usr/bin wrappers (deb verify step runs the real binary) - release matrix: win-x64, linux-x64/arm64, osx-x64/arm64 on native runners; win-arm64 dropped (Racket publishes no Windows ARM64 builds); Homebrew formula installs to libexec + bin wrappers, scoop is 64bit - ci.yml is now racket-only (unit + driver + MCP + E2E + smoke on ubuntu/windows);

The 0.5.x C# sources, their test projects and the .NET solution files leave with this commit; v0.6.0 ships from the Racket tree only. --- Benchpilot.slnx | 21 - Directory.Build.props | 13 -
