Extract cycle_or_clamp_ helper and simplify the increment/decrement
branches by flattening nested conditionals. Use LOG_STR_LITERAL for
cycling log strings.
ESP32 modules like the ESP32-PICO-V3-02 use a different flash pin
configuration where GPIO7 and GPIO8 are freely usable. The existing
ignore_pin_validation_error option allows bypassing this check but
the error message did not mention it, making it hard to discover.
The SerializationBuffer introduced in #13625 places a 640-byte buffer
on the stack. When handling HTTP requests on the ESP-IDF httpd task
(which has a default stack of 4096 bytes), the deep call chain from
handleRequest through JSON serialization and lwip_send can overflow.
Increase the httpd task stack by 256 bytes to restore headroom.
Fixes#14991
time.h was missing #include "esphome/core/defines.h", so USE_TIME_TIMEZONE
was never defined when compiling time.cpp. Both functions always took the
#else path, returning 0 offset and treating local time as UTC.
When Callback::create receives a function reference (e.g. void(&)(int)),
&callable gives the address of the function's machine code, not a
pointer variable. The memcpy then reads bytes from executable code
memory instead of copying a function pointer value.
Fix by decaying the callable into a local variable before memcpy,
which converts function references to function pointers stored on
the stack.
No current callers trigger this bug (all pass lambdas), but this
prevents incorrect behavior if bare function names are ever passed.
Boards like rpipico2 (Raspberry Pi Pico 2) don't have WiFi hardware
but ESPHome allowed configuring wifi on them, leading to linker errors
from missing CYW43 driver symbols. Add validation to catch this at
config time with a clear error message.
- Add wifi detection to the board generator by checking for
PICO_CYW43_SUPPORTED=1 in upstream extra_flags
- Add validation in wifi component to reject non-WiFi RP2040 boards

Add libretiny and zephyr to PLATFORM_SPECIFIC_COMPONENTS so they
are correctly filtered out when an incompatible platform is selected
for memory impact analysis. Previously, libretiny was missing from
the set, causing it to be included in esp32-idf builds and producing
a misleading comment showing both platforms.
message_name() returned bare string literals that stayed in RAM on
ESP8266. Change return type to const LogString * and wrap with LOG_STR()
so they are stored in flash. Update log_send_message_ to use
LOG_STR_ARG() accordingly.
Also fix clang-tidy: rename append_p_esp8266_ to append_p_esp8266,
add NOLINTNEXTLINE for conditionally-unused dump_field overloads.
