- 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
- 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)
- drop the ANDROID_PLATFORM block forcing PROCESS/DYNLIB/FFT off:
Android has /proc and dlopen and these features worked there in master
- __sighandler__: wrap PIProcess::currentPID() by PIP_HAS_PROCESS (0
fallback), the dumpApplicationToFile() call itself is already guarded
by PIP_INTROSPECTION && PIP_HAS_FILESYSTEM
- PISystemMonitor: guard /proc-related members (proc_dir/file/filem) and
code paths (startOnProcess, run() non-Windows part, gatherThread /proc
reader) by PIP_HAS_PROCESS/PIP_HAS_FILESYSTEM so the file compiles for
any flag combination, e.g. -DPIP_HAS_PROCESS=OFF -DPIP_HAS_FILESYSTEM=OFF
- pistatemachine_base.h checked non-existent macros __GXX_RTTI__/__RTTI__,
so on GCC/Clang desktop builds formatHash() always returned 0 and the
guard signature check in testGuard() never fired (UB on incompatible
signatures). Now the real PIP_HAS_RTTI (pibase_macros.h) is used.
- no-RTTI fallback: each Function<Args...> instantiation takes a unique
hash from a process-wide counter (a per-instantiation counter would
give every signature the same hash on first call).
- __pip_typename__ primary template: replace hard static_assert with a
generic fallback; containers/stream operators instantiate it for
arbitrary T in no-RTTI builds (Pico/arm-none-eabi has no RTTI), so the
assert made any no-RTTI build impossible. Explicit
__PIP_TYPENAME_DECLARE specializations still take precedence.
The stub member definitions lived in the header and were picked up by
every TU including piinit.h, causing multiple-definition link errors in
embedded (PIP_EMBEDDED) builds. Definitions now live only in piinit.cpp;
the stub implementation is compiled in the '#else' branch guarded by
PIP_HAS_THREADS (no-PIInit builds are unchanged).
File descriptor 0 is stdin (a valid fd). Using 0 as the 'not-open'
sentinel caused isCreate() to return false and destroy() to skip
close() when pipe() happened to allocate fds {0, 1} (e.g. in daemons
with closed stdio). POSIX convention: -1 = invalid fd.
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
