This becomes apparent when you are using MP stream protocol to read directly from input buffers. When you attempt to read(1) on a UART (and possibly other protocols) you have to wait for either the byte or the timeout. Fixes: - Waiting for a timeout after you have completed reading a correct and complete JSON off the input. - Raising an OSError after reading a correct and complete JSON off the input. - Eating more data than semantically owned off the input buffer. - Blocking to start parsing JSON until the entire JSON body has been loaded into a potentially large, contiguous Python object. Code you would write before: ``` line = board_busio_uart_port.read_line() json_dict = json.loads(line) ``` or reaching for fixed buffers and swapping them around in Python. Code that did not work before that does now: ``` json_dict = json.load(board_busio_uart_port) ``` - This removes the need for intermediate copies of data when reading JSON from micropython stream protocol inputs. - It also increases total application speed by parsing JSON concurrently with receiving on boards that read from UART via DMA. - It simplifies code that users write while improving their apps. 2019-02-21T16:09:44+00:00 Dan Halbert halbert@halwitz.org 2019-02-21T16:09:44+00:00 urn:sha1:10d3a20f8a639ad8ef5555e2142052190e8a7e13 2019-02-21T05:33:36+00:00 Dan Halbert halbert@halwitz.org 2019-02-21T05:33:36+00:00 urn:sha1:c5dbdbe88c099494cd14790b8c645020538eed27 2018-08-17T00:41:35+00:00 Scott Shawcroft scott@tannewt.org 2018-08-16T20:34:12+00:00 urn:sha1:2cd166b57370ab4877ec2d9666225faeac6127ce 2018-06-18T02:35:56+00:00 Damien George damien.p.george@gmail.com 2018-06-13T02:37:49+00:00 urn:sha1:e8398a58567cc94b866d46721fd06289601f5c8a With this patch objects are only checked that they have the stream protocol at the start of their use as a stream, and afterwards the efficient mp_get_stream() helper is used to extract the stream protocol C methods.
