- 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
- CMake: disable thread/socket-dependent modules (http_client, mqtt_client,
client_server) and fftw when the required feature flags are off;
client_server/cloud no longer tied to the crypt option
- host utils gated on filesystem and the modules they need
- Pico keeps the minimal set; generic FreeRTOS (ESP32) keeps filesystem,
sockets and serial as in master, module set limited to crypt/compress/io_utils
- PICAN, PIBroadcast, PIPackedTCP vanish without socket+threads
- PISerial: restore PISERIAL_NO_PINS (auto-enabled on PIP_EMBEDDED)
- PIFile: FREERTOS uses fopen/stat (no fopen64 in ESP-IDF newlib)
- drop invalid PICout buffer guards, guard PIObject::deleteLater,
remove (void)destroying hack, fake PIHIDevice non-Linux stub and the
redundant PICO_SDK guard in code_model_generator
Found while verifying -DPIP_HAS_THREADS=OFF / -DPIP_HAS_FILESYSTEM=OFF
smoke builds (pre-existing gaps of the branch):
- piinit.cpp: full implementation now requires PIP_HAS_THREADS as well
(the PIInit class is declared in piinit.h only with threads; without
threads PIInit is absent altogether, stub/absent branches unchanged)
- PIWaitEvent: drop the PIP_HAS_THREADS guard - it is a plain
pipe/select/WaitForMultipleObjects wrapper with no thread usage
(master had no guard), restores unistd.h include for PICAN etc.
- PIEthernet: guard server_thread_ member, server_func(), threaded
listen/stop parts and writeThreaded() calls by PIP_HAS_THREADS
- PIPeer: guard class/impl by PIP_HAS_THREADS (uses PIThread/PITimer/
PIDiagnostics), openDevice() /etc/pip.conf read by PIP_HAS_FILESYSTEM
- PIBinaryLog::restart(): guard threaded-read restart by PIP_HAS_THREADS
- PIIODevice::configure(config_file,...), PIConnection::configureFromConfig,
PIConfig include resolution: guard path-based bodies by PIP_HAS_FILESYSTEM
- PISerial::availableDevicesInfo(): guard /dev and /proc/tty scan by
PIP_HAS_FILESYSTEM
- PIHIDevice impl: requires filesystem (sysfs scan) in addition to threads
- PIPluginLoader::pluginsDirectories/findLibrary: guard PIFile/PIDir use
by PIP_HAS_FILESYSTEM (fallback: empty list / path as-is)
- pifile.cpp: drop '|| !defined(PIP_HAS_FILESYSTEM)' from the
_fopen_call_ condition and the redundant inner
'#ifdef PIP_HAS_FILESYSTEM' - the whole file is already inside
PIP_HAS_FILESYSTEM
- remove PISERIAL_NO_PINS (piplatform.h, piserial.cpp): the whole
piserial.cpp is inside PIP_HAS_SERIAL which is forced OFF for
Pico/FREERTOS, so the macro could never be active where it mattered;
keep the Windows/POSIX branches as-is
In the blocking read path (timeout_ms <= 0), the while loop had no
exit condition for readDevice() returning 0 (EOF) or -1 (error).
This caused an infinite busy-loop at 100% CPU. Added 'else break'
to exit the loop on read failure, matching the timeout branch
which already handles this case.
PIThread::stopAndWait now returns bool
PIKbdListener on Linux now use piwaitevent_p and can immediately stop
new base method piZeroMemory, also migrate all "memset 0" to piZeroMemory
apply some code analyzer recommendations
ICU flag now check if libicu exists
prepare for more accurate growth of containers (limited PoT, then constantly increase size)
in almost all methods removed timeouts in milliseconds, replaced to PISystemTime
PITimer rewrite, remove internal impl, now only thread implementation, API similar to PIThread
PITimer API no longer pass void*
PIPeer, PIConnection improved stability on reinit and exit
PISystemTime new methods
pisd now exit without hanging
