CircuitPython - a Python implementation for teaching coding with microcontrollers https://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=v1.9.4 2018-05-01T05:54:50+00:00 2018-05-01T05:54:50+00:00 Ayke van Laethem aykevanlaethem@gmail.com 2018-04-24T15:43:14+00:00 urn:sha1:d43c7377564b3e1be36f627a465df2c5779a1ae8 This is a more consistent use of errno codes. For example, it may be that a stream returns MP_EAGAIN but the mp_is_nonblocking_error() macro doesn't catch this value because it checks for EAGAIN instead (which may have a different value than MP_EAGAIN when MICROPY_USE_INTERNAL_ERRNO is enabled). 2018-04-10T03:41:32+00:00 Damien George damien.p.george@gmail.com 2018-03-07T06:48:53+00:00 urn:sha1:cf31d384f1d2ca09f817f154892eaa6860c10144 This patch moves the implementation of stream closure from a dedicated method to the ioctl of the stream protocol, for each type that implements closing. The benefits of this are: 1. Rounds out the stream ioctl function, which already includes flush, seek and poll (among other things). 2. Makes calling mp_stream_close() on an object slightly more efficient because it now no longer needs to lookup the close method and call it, rather it just delegates straight to the ioctl function (if it exists). 3. Reduces code size and allows future types that implement the stream protocol to be smaller because they don't need a dedicated close method. Code size reduction is around 200 bytes smaller for x86 archs and around 30 bytes smaller for the bare-metal archs. 2017-10-04T01:37:50+00:00 Damien George damien.p.george@gmail.com 2017-10-04T01:37:50+00:00 urn:sha1:a3dc1b1957d2c96d7c60c2c629c95077b03488a1 Header files that are considered internal to the py core and should not normally be included directly are: py/nlr.h - internal nlr configuration and declarations py/bc0.h - contains bytecode macro definitions py/runtime0.h - contains basic runtime enums Instead, the top-level header files to include are one of: py/obj.h - includes runtime0.h and defines everything to use the mp_obj_t type py/runtime.h - includes mpstate.h and hence nlr.h, obj.h, runtime0.h, and defines everything to use the general runtime support functions Additional, specific headers (eg py/objlist.h) can be included if needed. 2017-09-21T08:22:55+00:00 Damien George damien.p.george@gmail.com 2017-08-31T11:42:39+00:00 urn:sha1:7885a425d78a5a2fa7da5099cdd547a35f5e69dd The vstr argument to the calls to vstr_add_len are dynamically allocated (ie fixed_buf=false) and so vstr_add_len will never return NULL. So there's no need to check for it. Any out-of-memory errors are raised by the call to m_renew in vstr_ensure_extra. 2017-08-20T19:02:41+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2017-08-20T18:57:36+00:00 urn:sha1:e3383e9352ca7704e650b07038207719c60b56fb Per POSIX, this is EINVAL, so raises OSError(EINVAL). 2017-07-31T08:35:40+00:00 Alexander Steffen devel.20.webmeister@spamgourmet.com 2017-06-30T07:22:17+00:00 urn:sha1:55f33240f3d7051d4213629e92437a36f1fac50e There were several different spellings of MicroPython present in comments, when there should be only one. 2017-06-15T01:54:41+00:00 Damien George damien.p.george@gmail.com 2017-06-15T01:54:41+00:00 urn:sha1:48d867b4a68e53901aac87c2ff0f2a7e65f735c7 2017-05-29T08:36:05+00:00 Ville Skyttä ville.skytta@iki.fi 2017-05-29T07:08:14+00:00 urn:sha1:ca16c3821053e5bf2b87aeb10007f73f31dc1eac 2016-11-13T21:24:22+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2016-11-13T21:24:22+00:00 urn:sha1:59a1201da959ab01895361c0b5bb8bc1409f2b39 Its addition was due to an early exploration on how to add CPython-like stream interface. It's clear that it's not needed and just takes up bytes in all ports. 2016-10-27T19:13:45+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2016-10-27T19:12:59+00:00 urn:sha1:8a49905a2f268255cba7f7deb6c334b830d5943a
