- more readable code
- detect PIThread and PIIODevice
- try to gracefully stop thread or IODevice, wait with 10_ms and cycle object back to deletion queue if more needed
- on program shutdown also try to wait for thread or device actually stop, but with smaller timeout
- print which thread or IODevice hangs (can`t stop in timeout)
PIThread fix deadlock on join when thread in _startThread
PIProcess::optimizeMemory fix
PIThread refactoring:
- much more clear platform implementations
- single status instead of flags zoo
- more stability, using join instead of leaving detached
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.
- 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
- drop INTROSPECTION conjunctions (CMake dep table already forces THREADS+SOCKET)
- remove whole-file guards in client_server/process tests (CMake only compiles them when flags are ON)
- normalize single-flag '#if defined(PIP_HAS_X)' to '#ifdef PIP_HAS_X'
Guard PIConnection, thread primitives, PICodeParser and other feature
code behind PIP_HAS_THREADS/PIP_HAS_FILESYSTEM. In CMake generate the
feature flags summary from the single PIP_HAS_FLAGS list (used by the
add_definitions loop as well), default ICU to OFF and make introspection
also require PIP_HAS_SOCKET. Build system/thread test suites only when
the corresponding feature flags are enabled.
- Rename __PIP_TYPENAME_DECLARE to PIP_REGISTER_TYPENAME across all headers
- Add PIP_DECLARE_TYPENAME(name) macro for in-class type name declaration
- Replace all static const char * __pip_typename__() member functions with PIP_DECLARE_TYPENAME
- move __PIP_TYPENAME_DECLARE() calls inside PIP_HAS_* guards so -fno-rtti
builds compile with arbitrary reduced flag combinations
- guard PISerial declaration by PIP_HAS_SERIAL like other feature-gated classes
- reduce threaded read buffers to 1 KiB on embedded targets (PIIODevice,
PIPacketExtractor, PIEthernet)
- 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
- guard console subsystem (PIScreen/PIScreenTile/tiles/PITerminal/
PIKbdListener) by PIP_HAS_THREADS plus a TTY or Windows console
(new PIP_HAS_TTY platform macro) - termios is not available on
bare-metal newlib
- guard cloud subsystem (PICloudBase/Client/Server/TCP) by
PIP_HAS_SOCKET and PIP_HAS_THREADS
- add PIP_BUILD_CONSOLE/PIP_BUILD_CLOUD to the auto-disable flag
dependencies in CMake
- PIP_CAN (SocketCAN) is Linux-only, exclude other platforms
- on Pico keep sockets/MQTT off by default: pico-sdk lwip provides
only a partial POSIX socket layer (no netinet/in.h, poll.h)
- PITranslator: inline no-op definitions when PIP_HAS_FILESYSTEM is
off so the _tr literal links
- PIIODevice: guard read_func/write_func EVENT_HANDLERs (no-threads)
- piwaitevent_p.cpp: drop unused sys/ioctl.h include (missing on
arm-none-eabi, broke Pico builds)
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)
