Since commit da938a83b5 the tcp_arg() that is
set for the new connection is the new connection itself, and the parent
listening socket is found in the pcb->connected entry.
Use uos.dupterm for REPL configuration of the main USB_VCP(0) stream on
dupterm slot 1, if USB is enabled. This means dupterm can also be used to
disable the boot REPL port if desired, via uos.dupterm(None, 1).
For efficiency this adds a simple hook to the global uos.dupterm code to
work with streams that are known to be native streams.
Some users of this module may require the LwIP stack to run at an elevated
priority, to protect against concurrency issues with processing done by the
underlying network interface. Since LwIP doesn't provide such protection
it must be done here (the other option is to run LwIP in a separate thread,
and use thread protection mechanisms, but that is a more heavyweight
solution).
The bug polling for readability was: if alloc==0 and tcp.item==NULL then
the code would incorrectly check tcp.array[iget] which is an invalid
dereference when alloc==0. This patch refactors the code to use a helper
function lwip_socket_incoming_array() to return the correct pointer for the
incomming connection array.
Fixes issue #4511.
As mentioned in #4450, `websocket` was experimental with a single intended
user, `webrepl`. Therefore, we'll make this change without a weak
link `websocket` -> `uwebsocket`.
Previously crypto-algorithms impl was included even if MICROPY_SSL_MBEDTLS
was in effect, thus we relied on the compiler/linker to cut out the unused
functions.
Python defines warnings as belonging to categories, where category is a
warning type (descending from exception type). This is useful, as e.g.
allows to disable warnings selectively and provide user-defined warning
types. So, implement this in MicroPython, except that categories are
represented just with strings. However, enough hooks are left to implement
categories differently per-port (e.g. as types), without need to patch each
and every usage.
This header is deprecated as of mbedtls 2.8.0, as shipped with Ubuntu
18.04. Leads to #warning which is promoted to error with uPy compile
options.
Note that the current version of mbedtls is 2.14 at the time of writing.
It's more robust to have the version defined statically in a header file,
rather than dynamically generating it via git using a git tag. In case
git doesn't exist, or a different source control tool is used, it's
important to still have the uPy version number available.
