- 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)
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
maybe fix hang on PIEthernet::interrupt()
replace piLetobe with piChangeEndian:
* piChangeEndianBinary
* piChangeBinary
* piChangedBinary
PIDiagnostics::start now accept PISystemTime instead of number
add PITimer::start(PISystemTime, std::function<void()>) overload
