- cleanupExpired() drops sessions expired by tokenTtl or sessionIdleTimeout and is
called opportunistically on issuing a token, bounding the session table; it is
protected and self-locking so subclasses can run it periodically
- issueToken() refuses a token already used by an active session instead of
silently merging two sessions (login replies 500 on a generator collision)
- document that the token generator must be collision-resistant
- tests: SessionCleanupOnLogin, ManualCleanup, TokenCollisionRejected
- parse the Basic auth-scheme case-insensitively (RFC 7235), matching Bearer
- register the http_server test only when pip_http_server and pip_http_client
targets exist, so TESTS=ON without the HTTP modules does not fail to link
- add a Basic_LowercaseScheme test
The idle timeout is opt-in: when set with setSessionIdleTimeout(), a session
expires after that period without a successful request and every successful
request extends it. When unset (the default), sessions are not touched and keep
the previous behavior: the absolute tokenTtl applied to created, or living until
logout. Both deadlines can be combined and the earlier one wins.
- SessionRec: add last_used, drop the unused refresh_token field
- checkToken(): update last_used only while the idle timeout is enabled
- tests: IdleTimeout, IdleActivityExtendsSession, IdleDisabledKeepsSession,
HasSessionIdleTimeout
The server no longer stores user accounts. PIHTTPServerMultiUser is renamed to
PIHTTPServerSessionAuth and keeps only the in-memory session table: credential
verification is delegated to the pure virtual checkCredentials(), implemented by
a client subclass that owns the user storage.
- remove UserRec, addUser/removeUser/userExists/userCount and the password
check callback; add protected revokeToken()/revokeUserTokens() helpers
- add configurable login/logout route paths (default /api/login, /api/logout)
- call checkCredentials() without holding the internal lock and report 500 when
the token generator yields no data
- rewrite tests around a client subclass with its own user table
- PIHTTPServerBasicAuth: parse Authorization: Basic header, validate credentials via callback
- PIHTTPServerProtected: wrap any handler with auth check (basic or custom token)
- Integration tests for both modules (12 test cases)
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)
- 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
Declarations of PIConfig(PIString, DeviceMode), PIConfig(PIString,
PIStringList) and open(PIString, DeviceMode) now match their
filesystem-guarded definitions in piconfig.cpp (link error otherwise);
the path constructor definition is guarded as well since it calls the
guarded open(). String/device based overloads stay unguarded.
- merge the PICO_BOARD and PIP_FREERTOS blocks (90% duplicate) into one
embedded block; Pico+PICO_FREERTOS now adds -DPIP_FREERTOS so
pithread.cpp takes the FreeRTOS path instead of POSIX pthreads;
restore set(ICU OFF)/set(LOCAL ON) for FreeRTOS/embedded targets
- auto-disable dependent flags when PIP_HAS_THREADS=OFF:
PIP_HAS_PROCESS, PIP_HAS_SERIAL (PIProcess derives from PIThread,
PISerial/PIIODevice use PIThread) and INTROSPECTION (walks threads)
- LIBS_MAIN: link dl only with PIP_HAS_DYNLIB, pthread/util/rt only with
PIP_HAS_THREADS (rt was never linked on APPLE), socket on QNX_HOST only
with PIP_HAS_SOCKET; WIN32 list untouched - arm-none-eabi has no
libdl/libpthread/librt so Pico firmware links again
- collapse repeated 'NOT DEFINED PICO_SDK_PATH' utils checks into
_PIP_HOST_TOOLS variable
- FindPIP.cmake: check PIP_FREERTOS instead of the never-set
PIP_EMBEDDED CMake variable (as in master)
- drop unused set(PIP_MICRO ON) from esp-pip
- wrap PIGrabberBase/PIPipelineThread in #ifdef PIP_HAS_THREADS like
pithread.h so 'pip.h' compiles in no-threads builds
- 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).
