On ESP8266, there're 2 different interfaces. Pretending it's not the case
desn't make sense. So, network.WLAN() now takes interface id, and returns
interface object. Individual operations are then methods of interface
object. Some operations require i/f of specific type (e.g. .connect()
makes sense only for STA), other are defined for any (e.g. .ifconfig(),
.mac()).
Building in 32-bit mode was only to reduce binary size on 64-bit machines
and is otherwise not needed. Having it forced to 32-bit meant an
unnecessary dependency on 32-bit libraries that is now removed.
It can happen that a socket gets closed while the pbuf is not completely
drained by the application. It can also happen that a new pbuf comes in
via the recv callback, and then a "peer closed" event comes via the same
callback (pbuf=NULL) before the previous event has been handled. In both
cases the socket is closed but there is remaining data. This patch makes
sure such data is passed to the application.
If the heap is locked, or memory allocation fails, then calling a bound
method will still succeed by allocating the argument state on the stack.
The new code also allocates less stack than before if less than 4
arguments are passed. It's also a tiny bit smaller in code size.
This was done as part of the ESA project.
tools/pydfu.py is now the recommended way of deploying a DFU file. Old
behaviour of dfu-util can be obtained by passing USE_PYDFU=0 when invoking
make.
The main README.md file has been updated to reflect this change.
