[ISSUE 617] ProtectionManager Without Ethernet / Fault Runtime Redesign by jorgesg82 · Pull Request #628 · Hyperloop-UPV/ST-LIB

jorgesg82 · 2026-04-22T19:05:06Z

Summary

Closes #617

This PR removes the protection subsystem's dependency on Ethernet and redesigns the global fault runtime around a permanent top-level machine owned by FaultController.

The new design keeps the global states fixed as OPERATIONAL and FAULT, and leaves the user responsible only for declaring an optional nested operational state machine and an optional on_fault_enter callback.

Main Changes

Replace the old ProtectionManager model with ProtectionEngine and a single flat protection collection.
Remove the low/high protection split and the old boundary-driven integration model.
Make FaultController the only owner of the global fault runtime and the only valid entry point to global fault through FaultController::request_fault(...).
Move real bootstrap wiring to Board::init().
Install diagnostics sinks and the fault runtime early during bootstrap so early faults are latched and not lost.
Unify runtime reporting through diagnostics with PANIC(...), FAULT(...), WARNING(...), and INFO(...).
Separate FaultCause from DiagnosticRecord.
Make protection time accumulation use Scheduler::get_global_tick() instead of loop-frequency assumptions.
Update tests and documentation to match the new integration model.

Breaking Changes

Board now requires the fault policy type as its first template argument.
The user no longer programs transitions to the global FAULT state.
The user no longer owns the top-level runtime state machine.
The protection API is now ProtectionEngine plus Protections::Rules::*.
The intended bootstrap path is Board::init(), not legacy STLIB::* or STLIB_LOW/HIGH::* entry points.

New Board API

using AppFaultPolicy = ST_LIB::FaultPolicy<app_machine, on_fault_enter>;
using AppBoard = ST_LIB::Board<AppFaultPolicy, led, pwm, adc>;

If the application does not need a nested machine:

using AppBoard = ST_LIB::Board<ST_LIB::FaultPolicyNoMachine<on_fault_enter>, led, pwm, adc>;

If the application needs neither a nested machine nor a fault-entry callback:

using AppBoard = ST_LIB::Board<ST_LIB::DefaultFaultPolicy, led, pwm, adc>;

Fault Entry Contract

Protections enter global fault by calling FaultController::request_fault(...).
PANIC(...) and FAULT(...) also map to FaultController::request_fault(...).
WARNING(...) and INFO(...) publish diagnostics only and do not enter global fault.

Migration Guide

Replace legacy board declarations with Board<YourFaultPolicy, ...>.
Move any operational user machine under FaultPolicy<app_machine, on_fault_enter>.
Stop programming direct transitions to global FAULT.
Replace old protection registration with ProtectionEngine::create_protection(...) and Protections::Rules::*.
Replace old reporter usage with PANIC(...), FAULT(...), WARNING(...), and INFO(...).
Ensure bootstrap happens through Board::init().
Ensure the loop drives:

FaultController::check_transitions();
ProtectionEngine::evaluate();
Diagnostics::Hub::flush();

- FaultController: decouple FaultCause from DiagnosticRecord; add early-fault bootstrap so faults before start() are latched and the runtime starts directly in FAULT; remove FaultRuntime (superseded) - Diagnostics::Hub: fixed-capacity history ring and pending queue; flush_urgent() drains urgent records first; no heap in publish/flush - RecordFactory: explicit conversion FaultCause -> DiagnosticRecord via FaultDiagnosticMapper; runtime_panic / runtime_fault / runtime_warning / runtime_info factories with RuntimeSourceMetadata - Runtime reporters: PANIC/FAULT use std::source_location, format into fixed stack buffer, no shared mutable metadata (ISR-safe); WARNING/INFO go through RuntimeDiagnosticReporter; ErrorHandler/InfoWarning are now thin compatibility aliases - ProtectionEngine: evaluate() throttles fault notifications via notify_delay_in_microseconds; non-fatal rule edges published to Hub

Replace direct ErrorHandler / InfoWarning calls with the new macro facade (PANIC, FAULT, WARNING, INFO) across all HALAL peripheral drivers, Ethernet/TCP/UDP stacks, and service implementations. Fixes MDMA callsite that was using invalid string concatenation with a printf-style API: PANIC("MDMA Transfer Error, code: %lu", error_code).

- CMakeLists: remove FaultRuntime from build, add DiagnosticSinks - ST-LIB.hpp: update includes after FaultRuntime removal - StaticVector, MeanCalculator, Zeroing, StateOrder variants: minor include and compatibility fixes - README: update status notes

- DiagnosticsHub tests: history when no sinks, per-sink retry, bounded pending queue, reinstall clears latch, fault transitions once, delegation to nested operational machine, early-fault bootstrap (fault before start), source location captured in runtime reporters, invalid rule config rejected without side effects - PANIC/FAULT enter global FAULT and publish URGENT diagnostic record - WARNING/INFO publish without entering FAULT - ProtectionEngine: evaluate triggers fault and publishes protection event - TestAccess: white-box accessors for DiagnosticsHub and ProtectionEngine - Update adc_test, spi2_test, dma2_test, encoder_test, common_tests for new reporter API

Documents the current model: FaultController ownership, FaultPolicy nesting, PANIC/FAULT/WARNING/INFO semantics, early-fault bootstrap, FaultCause vs DiagnosticRecord separation, Diagnostics Hub memory policy, and C++23 design choices.

publish_edge_events(...) and request_fault_if_due(...) are static member templates of ProtectionEngine, but they’re called unqualified from inside a lambda passed to visit. Unqualified lookup inside the lambda won’t find class members, so this should fail to compile on standard-conforming compilers. Qualify the calls (e.g., ProtectionEngine::publish_edge_events(...) / ProtectionEngine::request_fault_if_due(...)) or move these helpers into the surrounding anonymous namespace as free functions.

+RuntimeFatalMessage format_runtime_fatal_message(const char* format, va_list arguments) {
+    RuntimeFatalMessage message{};
+    const int32_t written = vsnprintf(message.buffer, sizeof(message.buffer), format, arguments);
+    message.truncated = written < 0 || static_cast<size_t>(written) >= sizeof(message.buffer);
+    return message;


format_runtime_fatal_message consumes a va_list passed by value via vsnprintf. On some platforms va_list is a mutable type, so consuming it in a helper can leave the caller’s va_list in an indeterminate state before va_end, which is undefined behavior. Make a local copy with va_copy inside the helper (or pass a va_list* and copy there) and call vsnprintf on the copy, then va_end the copy in the helper.

+


publish_runtime_diagnostic consumes a va_list passed in from the caller. Because va_list may be a mutable type, consuming it in this helper can make the caller’s va_list indeterminate before va_end, which is undefined behavior on some ABIs. Copy the va_list with va_copy in the helper (or in the caller) and pass/consume the copy instead.

+    const uint64_t tick = Scheduler::get_global_tick();
+    const uint64_t last_publish_tick = protection.get_last_fault_publish_tick();
+    if (last_publish_tick != 0 &&
+        tick < last_publish_tick + Protections::Config::notify_delay_in_microseconds) {
+        return;


The notify throttling check uses tick < last_publish_tick + notify_delay. Since this is unsigned arithmetic, last_publish_tick + notify_delay can overflow and break the comparison when last_publish_tick is near UINT64_MAX. Prefer an overflow-safe form like tick - last_publish_tick < notify_delay (guarding last_publish_tick != 0) to keep throttling correct across wraparound.

PhasedPWM.old has no 'new' counterpart, others that were deleted already have a new implementation, like Encoder or InputCapture.

Maybe it would be fine to keep the old implementations that don't have a new implementation done

Isn't it just a configuration layer over a PWM? If so, it could just be replaced by a funciton in the pwm class, but I don't actually know how it works so don't take my word

It does some different things from a normal pwm and does it all with lower level handling than what was there in the old PWM.cpp and DualPWM.cpp, though there is also a couple comments that imply it was unfinished...

victor-Lopez25 · 2026-04-24T10:09:05Z

Same as the other, this is not implemented and might be good to keep until it is implemented.

It is just 2 PWMs, there's not much logic in it. In any case I would just refactor it now rather than keep it, so that we can remove the rest of the old code. But it is not so useful really, and I think no one is using it right now

It looks like HalfBridge uses Phased PWMs, I agree that this implementation is not worth keeping

It would be better to have a struct, like a string builder to keep the current offset since with this it will call bounded_strnlen every call which is O(n) and pretty slow.

For an example implementation of a string builder, see: https://github.com/victor-Lopez25/viclib/blob/main/vl_build.h#L1099

Scheduler::get_global_tick() assumes the board has been started up so Scheduler_global_timer is not null, this condition is not necessary and will make this function slower for no reason
