This is tricky to get right so we detect this case and raise a NotInplementedError instead of crashing.

The first one was then discarded. This refactor makes it so that a new instance is only created if the user __new__ function doesn't exist. 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. 2017-07-18T01:57:39+00:00 Alexander Steffen devel.20.webmeister@spamgourmet.com 2017-06-29T21:14:58+00:00 urn:sha1:299bc625864b9e624ed599c94a5f95870516139a The code conventions suggest using header guards, but do not define how those should look like and instead point to existing files. However, not all existing files follow the same scheme, sometimes omitting header guards altogether, sometimes using non-standard names, making it easy to accidentally pick a "wrong" example. This commit ensures that all header files of the MicroPython project (that were not simply copied from somewhere else) follow the same pattern, that was already present in the majority of files, especially in the py folder. The rules are as follows. Naming convention: * start with the words MICROPY_INCLUDED * contain the full path to the file * replace special characters with _ In addition, there are no empty lines before #ifndef, between #ifndef and one empty line before #endif. #endif is followed by a comment containing the name of the guard macro. py/grammar.h cannot use header guards by design, since it has to be included multiple times in a single C file. Several other files also do not need header guards as they are only used internally and guaranteed to be included only once: * MICROPY_MPHALPORT_H * mpconfigboard.h * mpconfigport.h * mpthreadport.h * pin_defs_*.h * qstrdefs*.h 2016-01-11T00:49:27+00:00 Damien George damien.p.george@gmail.com 2016-01-03T15:55:55+00:00 urn:sha1:5b3f0b7f39bd67cc9182993c288f09f67a0890df The first argument to the type.make_new method is naturally a uPy type, and all uses of this argument cast it directly to a pointer to a type structure. So it makes sense to just have it a pointer to a type from the very beginning (and a const pointer at that). This patch makes such a change, and removes all unnecessary casting to/from mp_obj_t. 2016-01-11T00:48:41+00:00 Damien George damien.p.george@gmail.com 2016-01-03T09:59:18+00:00 urn:sha1:a0c97814dfcb0debbde8be99539e3d5ca2334e54 This patch changes the type signature of .make_new and .call object method slots to use size_t for n_args and n_kw (was mp_uint_t. Makes code more efficient when mp_uint_t is larger than a machine word. Doesn't affect ports when size_t and mp_uint_t have the same size. 2015-05-04T10:08:40+00:00 Damien George damien.p.george@gmail.com 2015-05-03T22:23:18+00:00 urn:sha1:47b9809d231c4359c56316130a76f13de2b907f7 Addresses issue #1203. 2015-04-11T15:54:37+00:00 Damien George damien.p.george@gmail.com 2015-04-01T14:10:50+00:00 urn:sha1:b1bbe966c408901ae64ea8c8b468694c47d05b1a This simplifies the API for objects and reduces code size (by around 400 bytes on Thumb2, and around 2k on x86). Performance impact was measured with Pystone score, but change was barely noticeable.
