Sin esta linea la variante se queda en el nombre del chip, asi que TODA placa
compila como dev-kit generico y variants/<VARIANTE>/pins_arduino.h nunca entra
en el include path: los nombres propios de la placa (D0..D10 en una XIAO, la
serigrafia de las M5) sencillamente no existen. Justo los sketches que la gente
copia de la wiki del fabricante.
El helper que deriva la variante del FQBN leyendo boards.txt ya estaba; faltaba
la plantilla que la consume. Sigue pendiente rellenar 'arduinoVariant' en
normalized para que surta efecto (ver F7.6 en velxio-prod).
arduino-esp32's WiFiClientSecure/ssl_client.cpp wraps its ENTIRE body
(start_ssl_client, ssl_init, send_ssl_data, ...) in
#if !defined(MBEDTLS_KEY_EXCHANGE_SOME_PSK_ENABLED) ... #else <body> #endif
ESP-IDF's mbedtls defaults the PSK key-exchange modes OFF, so the object
compiled empty and any sketch using WiFiClientSecure — including
HTTPClient.begin(url), which links the secure client even for http:// —
failed to link with "undefined reference to start_ssl_client". Commenting
out begin() let the optimizer drop the unused client, which is why it
"compiled when commented".
- sdkconfig.defaults.in: enable the PSK key-exchange ciphersuites
(CONFIG_MBEDTLS_PSK_MODES + the four KEY_EXCHANGE_*PSK), matching
arduino-esp32's own sdkconfig.
- espidf_compiler: ESP-IDF only seeds sdkconfig from sdkconfig.defaults when
sdkconfig is ABSENT. Persistent build dirs live in the build volume and
keep a stale sdkconfig across image rebuilds, so the new CONFIG_* would
never reach kconfig. Drop the generated sdkconfig when the rendered
defaults change so it re-seeds on configure.
- test: assert the rendered sdkconfig enables PSK.
Verified end-to-end: the reported WiFi+HTTPClient sketch now compiles to a
1.1 MB binary (was a hard link error before).
Backend:
- api/routes/compile.py accepts board-specific compile options
and dedups in-flight identical requests
- services/espidf_compiler.py expanded ESP-IDF wrapper with the new
options surface (sdkconfig.defaults.in
template added)
- services/arduino_cli.py honour the new options envelope
- services/esp32_lib_bridge.py thread board options through to QEMU
Tests:
- tests/test_compile_request_dedup.py end-to-end dedup behaviour
- tests/test_espidf_options.py covers the new options parsing
Frontend:
- services/compilation.ts client-side mirror — sends the new
options field on every compile request
