0.18.0

[ssilverman]

Added

• Added a "Notes on ordering and timing" section to the README.
• Added a README section that discusses EthernetClient::connect() and its return values.
• Added non-blocking TCP connection functions, connectNoWait(), that are equivalent to the connect() functions but don't wait for the connection to complete.
• Added EthernetUDP::beginWithReuse() and beginMulticastWithReuse() functions to replace the corresponding begin-with-reuse-parameter versions.
• Added printing the link speed and duplex in the IPerfServer example.
• Added an "Asynchronous use is not supported" section to the README.
• New EthernetClass::onInterfaceStatus(callback) and interfaceStatus() functions for tracking the network interface status.
• Added a check to ensure lwIP isn't called from an interrupt context.

Changed

• Wrapped LWIP_MDNS_RESPONDER option in lwipopts.h with #ifndef and added it to the README.
• Made EthernetClass::loop() non-static.
• Changed serial output in examples to use CRLF line endings.
• Changed EthernetClient::connect() internals to call close() instead of stop() so that any cleanup doesn't block.
• Updated EthernetClient::connect() to return some of the error codes defined at Ethernet - client.connect().
• Changed EthernetServer::begin()-with-Boolean-reuse-parameters to be named beginWithReuse(). This avoids too many overloads with mysterious Boolean arguments.
• Changed EthernetServer::operator bool() to be const.
• Changed EthernetServer::end() to return void instead of bool.
• Changed MDNSClass::begin(hostname) and DNSClient::getHostByName() to treat a NULL hostname as an error; they now explicitly return false in this case.
• Changed MDNSClass::end() to return void instead of bool.
• Changed examples that use unsigned char to use uint8_t in appropriate places.
• EthernetUDP::begin functions now call stop() if the socket is listening and the parameters have changed.
• MDNSClass::begin(hostname) now calls end() if the responder is running and the hostname changed.
• Changed both EthernetServer and EthernetUDP to disallow copying but allow moving.
• Changed raw frame support to be excluded by default. This changed the QNETHERNET_DISABLE_RAW_FRAME_SUPPORT macro to QNETHERNET_ENABLE_RAW_FRAME_SUPPORT.
• Changed tcp_pcb member accesses to use appropriate TCP API function calls. This fixes use of the altcp API.

Removed

• EthernetServer and EthernetUDP begin functions that take a Boolean reuse parameter.

Fixed

• EthernetUDP::begin functions now call stop() if there was a bind error.
• Fixed EthernetClient::setNoDelay(flag) to actually use the flag argument. The function was always setting the TCP flag, regardless of the value of the argument.
• Fixed printing unknown netif name characters in some debug messages.
• Fixed EthernetClient::connect() and close() operations to check the internal connection object for NULL across yield() calls.
• Fixed lwip_strerr() buffer size to include the potential sign.
• Don't close the TCP pcb on error since it's already been freed.
