CircuitPython - a Python implementation for teaching coding with microcontrollers https://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=3.0.0-beta.1 2017-09-26T01:59:11+00:00 2017-09-26T01:59:11+00:00 David Lechner david@lechnology.com 2017-09-25T01:15:48+00:00 urn:sha1:62849b7010abffb7b0a9c9875930efe7cb77519c This adds a new configuration option to print runtime warnings and errors to stderr. On Unix, CPython prints warnings and unhandled exceptions to stderr, so the unix port here is configured to use this option. The unix port already printed unhandled exceptions on the main thread to stderr. This patch fixes unhandled exceptions on other threads and warnings (issue #2838) not printing on stderr. Additionally, a couple tests needed to be fixed to handle this new behavior. This is done by also capturing stderr when running tests. 2017-08-15T01:53:36+00:00 Stefan Naumann me@stefannaumann.de 2017-07-24T16:55:14+00:00 urn:sha1:ace9fb54053c29574bdf81ffacc5ddcf9d4b45d9 It enables all the DEBUG_printf outputs in the py/ source code. 2017-06-14T04:43:50+00:00 Damien George damien.p.george@gmail.com 2017-06-14T04:43:50+00:00 urn:sha1:e374cfff80c37b96b03d4438e475e405b03e6d61 2017-03-29T01:56:17+00:00 Damien George damien.p.george@gmail.com 2017-03-25T08:35:08+00:00 urn:sha1:6213ad7f466df12c734dc527993bbb46c9d9eb5c This patch changes mp_uint_t to size_t for the len argument of the following public facing C functions: mp_obj_tuple_get mp_obj_list_get mp_obj_get_array These functions take a pointer to the len argument (to be filled in by the function) and callers of these functions should update their code so the type of len is changed to size_t. For ports that don't use nan-boxing there should be no change in generate code because the size of the type remains the same (word sized), and in a lot of cases there won't even be a compiler warning if the type remains as mp_uint_t. The reason for this change is to standardise on the use of size_t for variables that count memory (or memory related) sizes/lengths. It helps builds that use nan-boxing. 2017-03-28T11:37:26+00:00 Damien George damien.p.george@gmail.com 2017-03-28T11:37:26+00:00 urn:sha1:94c41bb06f6482ece0717c5bd63266b8da063caa Saves 168 bytes on bare-arm. 2017-03-06T06:01:56+00:00 Damien George damien.p.george@gmail.com 2017-02-27T12:56:46+00:00 urn:sha1:05fe66f68a1cf1b7587c55149472ab7bca843631 Each threads needs to have its own private references to its current locals/globals dicts, otherwise functions running within different contexts (eg imported from different files) can behave very strangely. 2017-02-15T00:28:02+00:00 Damien George damien.p.george@gmail.com 2017-02-05T23:47:20+00:00 urn:sha1:234f07f16cc845128658cc0b39ac681cae5a8fba It's more efficient using the system mutexs instead of synthetic ones with a busy-wait loop. The system can do proper scheduling and blocking of the threads waiting on the mutex. 2016-10-17T01:17:37+00:00 Damien George damien.p.george@gmail.com 2016-10-17T01:17:37+00:00 urn:sha1:7d0d7215d2575a2d36d34c9a13b58cade0610a28 Saves the following number of bytes of code space: 176 for bare-arm, 352 for minimal, 272 for unix x86-64, 140 for stmhal, 120 for esp8266. 2016-10-07T02:31:59+00:00 Damien George damien.p.george@gmail.com 2016-10-07T02:31:59+00:00 urn:sha1:3a0a7717304cc34a4d6ef55f767666c918c185b5 This is an often used code pattern, and its use reduces code size of the core by about 100 bytes. 2016-09-21T14:23:16+00:00 Damien George damien.p.george@gmail.com 2016-09-21T00:52:53+00:00 urn:sha1:93c4a6a3f70e389b466fbc7a4f1ad2e1df87c93f One can instead lookup __name__ in the modules dict to get the value.
