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. 2020-04-27T12:46:48+00:00 Jeff Epler jepler@gmail.com 2020-04-27T12:45:57+00:00 urn:sha1:1a6df71cecbfdfe0a2d1fbe081ead2cbce48cf29 2020-04-26T15:12:56+00:00 Jeff Epler jepler@gmail.com 2020-04-26T15:12:56+00:00 urn:sha1:c016ea6f0a090663f96dc84c430ff7ab722e4096 PR#2802 missed the submodule update itself. 2020-04-14T15:09:00+00:00 Jeff Epler jepler@gmail.com 2020-04-13T21:03:35+00:00 urn:sha1:cc21bed0e40e10790478cb643b9e5bd831069804 2020-04-14T00:00:16+00:00 Jeff Epler jepler@gmail.com 2020-04-13T21:03:35+00:00 urn:sha1:ca9796470115cef7ec22e9f59a3e68c319a5c32e 2020-03-17T13:32:52+00:00 Jeff Epler jepler@gmail.com 2020-03-16T21:23:38+00:00 urn:sha1:772ac705d3cbcdbc9cb139c7433a8e6e40db6f0d 2020-03-09T19:48:52+00:00 Jeff Epler jepler@gmail.com 2020-03-09T19:48:52+00:00 urn:sha1:eab9b670d8a8f57c94ec1375cd5cea64fe7b1df8 The only delta we were carrying was in the README. 2020-02-27T20:14:05+00:00 Jeff Epler jepler@unpythonic.net 2020-02-27T20:14:05+00:00 urn:sha1:39cfe32c345781b32d235353c2e59acacbc32dc6 2020-02-27T17:03:03+00:00 Jeff Epler jepler@gmail.com 2020-02-04T16:24:37+00:00 urn:sha1:fa3b9eba926525751d0968aef88317ce5ad25003
