PocketFFT (3rd/pocketfft, vendored 2018 version) cannot be compiled with
-fno-exceptions, which PIP uses on all non-Windows/non-Android targets.
This adds the proposed upstream patch adding a POCKETFFT_NO_EXCEPTIONS
option (error paths abort with a diagnostic instead of throwing), plus
the PR description for submission to mreineck/pocketfft.
Verified: PIP builds with current upstream master + this patch and
'-fno-exceptions -DPOCKETFFT_NO_EXCEPTIONS -DPOCKETFFT_NO_MULTITHREADING'
and passes the FFT functional test suite.
After the upstream PR is merged, bump the vendored header and drop the
local workarounds.
change CMAKE_CXX_STANDARD to 17
add PIByteArray(PIMemoryBlock)
PIJSON print functions now correctly handle top-level node, print name only for non-top-level
PIThread:
- remove old V singleton V, migrate to modern STATIC_INITIALIZER and common singleton
- add PowerPolicy - now implemented only for Windows, if SetThreadInformation available, then use, else try to use SetThreadIdealProcessor. Mixed cores not supported for SetThreadIdealProcessor case.
PIThreadPoolLoop: add setPriority() and setPowerPolicy()
The operator<< / operator>> templates for MessageConst / MessageMutable
added in 4d8b7430 have no users in the tree (libs, tests, utils, main).
Drop them along with the pibinarystream.h include they required; the
binary-stream fallback static_assert in pibinarystream.h already gives a
clear compile error if external code ever streams an MQTT message.
Replace scattered option() calls, PIP_HAS_DEPS_* variables, and while-loop
resolver with pip_feature_flag() function and pip_resolve_feature_flags()
macro. Dependencies are declared inline and resolved in a single pass.
- CMake: drop PIP_HAS_SERIAL -> PIP_HAS_THREADS dependency and the forced
PIP_HAS_SERIAL=OFF for PICO_BOARD, so serial can be built on Pico
- piserial.cpp: guard termios/stty code (tcgetattr/tcsetattr/tcflush/tcdrain,
TIOCSBRK/TIOCCBRK, TIOCMBIS/TIOCMBIC/TIOCMGET, termios members, sys/ioctl.h
and termios.h includes) with PIP_HAS_TTY; O_NOCTTY replaced by
PISERIAL_NOCTTY (0 on no-TTY targets)
- add missing #ifndef fallbacks for B110..B115200 used by convertSpeed()
when termios.h is absent
- guard thread-only PIIODevice API calls (isThreadedRead/stopThreadedRead)
with PIP_HAS_THREADS in closeDevice/readDevice
- gate the availableDevicesInfo() test loop with PIP_HAS_FILESYSTEM||WINDOWS
(device enumeration is a filesystem feature)
- AGENTS.md: note that clang-format-18 is applied automatically on file edits
- use LFS64 file/stat APIs only on glibc/Windows (absent in musl)
- use plain sched_priority outside glibc
- do not declare pow10(double) where the system provides C23 pow10() (musl)
- ICU is off by default: modern ICU (>= 75) needs C++17 for its headers,
the project is built with C++11; enable explicitly with -DICU=ON
- fix latent crash: PIThread::setThreadName() read the thread handle from
inside the new thread; the handle is not guaranteed to be visible before
start (musl publishes it later), rename the calling thread via
pthread_self() instead
