Fix dependency tree so that lwip doesn't depend on any specific network
interface component.
Network interface drivers shall depend on esp_netif.
esp_netif shall depend on lwip (but not on any specific interface
driver) -- it optionally depends on vfs and esp_eth (need ethernet
header for L2/bridge mode)
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.
- Allows users to manually intercept and process the HTTP redirection
when disable_auto_redirect (from the esp_http_client handle) is set to true
Closes https://github.com/espressif/esp-idf/issues/8029
Reason:
For example, if an url is lack of leading 'http:' by mistake, it causes to http_parser_parse_url() cannot parse http host item,
and then pass the null host pointer to _get_host_header(), crash happens.
Fix:
http added null pointer check now.
Closes https://jira.espressif.com:8443/browse/ESPAT-953
For https connection `ESP_TLS_ERR_SSL_WANT_READ` of esp_transport_read was getting treated as error.
Treated this as a timeout to fix connection abort issue!
Also handled http connection EAGAIN with `errno == EAGAIN` check.

In esp_http_client and esp_websocket_client components, esp_transport_tcp_set_keep_alive has been called and keep-alive config has been saved in ssl->cfg.keep_alive_cfg,
So no need to call esp_transport_ssl_set_keep_alive again.
