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
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)
fork() can return -1 on error (too many processes, out of memory).
The old code treated pid_ == -1 as a successful fork, entering the
parent branch and calling waitpid(-1, ...) which waits for ANY
child process. Added explicit check: close pipes, free memory,
and return on fork failure.
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)
