Adds the WITH_HARDWARE_PROTOCOL_V2 build option and the eu07.ini entries
which configure it: uart2 declares a serial link and may be repeated for
several controllers, the remaining uart2* entries tune frame size,
heartbeat, rate limits and logging. UART v1 is untouched and both may be
active at the same time on different ports.
The driver mode starts the manager when at least one link is configured
and pumps it from the input polling loop, and the debug panel gains a
Hardware Protocol v2 section reporting link and session condition,
packet rates, round trip time, protocol and transport error counters and
whatever diagnostics the device itself reports, with switches for
protocol and frame logging.
std::uniform_real/int_distribution has UB when min>max. The old "fancy Random"
used interpolate(a,b,t) which tolerated a>b; the migration to
std::uniform_real_distribution did not, and only one inverted call site was
fixed by hand. Swap the bounds inside Random()/Random(int)/LocalRandom() so
every call site is safe, and reorder the two inverted literal calls in
Driver.cpp (fActionTime buzzer / departure delay) for readability.
The dumb3d->glm / utilities-simplification refactor replaced the old custom
clamp() (which tolerated Lo>Hi, returning the upper bound) with std::clamp,
where inverted bounds are undefined behaviour. Only a few sites were patched
afterwards, by hand, with std::minmax plumbing (incl. a stray `static` inside
a per-axle loop). Others silently produced wrong results in the AI braking /
acceleration path.
Add a safe_clamp() helper (normalizes inverted bounds) and use it ONLY where
Lo<=Hi cannot be proven at compile time (config min/max pairs, sign-dependent
expressions, container underflow). Sites with constant bounds or [0, x>=0]
keep std::clamp. Remove the manual std::minmax workarounds and rewrite the
damaged-track jolt code value-first.
Consolidates platform-specific config-directory logic (APPDATA on Windows,
~/Library/Application Support on macOS, ~/.config on Linux) into a single
user_config_path(filename) function in utilities/utilities.{cpp,h}, removing
copy-pasted #ifdef blocks from application.cpp, editor/editorSettings.cpp,
input/{keyboard,gamepad,drivermouse,uart}input.cpp.
Three small source tweaks that let the OpenGL renderer build and run
on Apple Silicon without affecting the Windows/Linux paths:
- stdafx.h: use GLM_FORCE_NEON on ARM64 instead of GLM_FORCE_AVX2.
AVX2 pulls <immintrin.h>, which clang on ARM64 rejects because
the x86 intrinsics are unimplemented.
- utilities/utilities.cpp: provide an Apple libc++ fallback for
Now() using localtime_r + strftime, since
std::chrono::current_zone() is not yet implemented there.
- audio/audio.h: prefer Khronos-style <AL/al.h> headers when they
are on the include path (brew openal-soft) and fall back to the
deprecated Apple OpenAL.framework's <OpenAL/al.h> only otherwise.
