lwip was added to common requirements list to provide "sys/socket.h"
header to all components without additional requirements specified.
However, lwip pulls in a lot of dependencies on other components.
This commit removes lwip from common requirements to reduce the number
of components in G1-only apps.
To compensate for this removal, the following changes are made:
- newlib (which is a common requirement) has a public dependency on
lwip if lwip is present in the build. This ensures that sys/socket.h
is available as long as lwip component is included into the build.
- lwip is now a public requirement of esp-tls since esp_tls.h includes
sys/socket.h header.
- lwip is now a public requirement o esp_http_client because
sys/socket.h is included from esp_http_client.h
- lwip is now a private requirement of esp_wifi for "smartconfig_ack"
- lwip is now a private requirement of mqtt for socket functions
- lwip is now a public requirement of tcp_transport because
esp_transport_tcp.h includes sys/socket.h header.
- mbedtls checks if lwip component is present in the build. If yes,
net_sockets.c is added to the build, along with the dependency on
lwip. Previously lwip was a public requirement of mbedtls
unconditionally.
system/g1_components test app is updated to reflect the changes
Default public dependencies of a component before and after this
change, except common requirements:
- esp_timer (public dependency of freertos)
- bootloader_support (public dependency of esp_hw_support)
- vfs (public dependency of lwip)
- esp_wifi (public dependency of lwip)
- esp_event (public dependency of esp_wifi)
- esp_netif (public dependency of esp_event)
- esp_eth (public dependency of esp_netif)
- esp_phy (public dependency of esp_wifi)
After:
- esp_timer (public dependency of freertos)
- bootloader_support (public dependency of esp_hw_support)
Altogether, the following components have been always added as
public requirements to all other components, and are not added now
([breaking-change]):
- lwip
- vfs
- esp_wifi
- esp_event
- esp_netif
- esp_eth
- esp_phy
Application components now need to explicitly declare dependencies on
these components.
added docs and tests for mqtt library, small fixes (removed warnings, option for custom outbox, websocket bug fixed for longer transports). refactored to use common tcp_transport component, support for CMake build system.
Closes#2108
