CircuitPython - a Python implementation for teaching coding with microcontrollers https://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=v1.6 2016-01-11T00:49:27+00:00 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. 2016-01-03T18:51:26+00:00 stijn stinos@zoho.com 2014-12-23T13:06:55+00:00 urn:sha1:3c014a67ea0c2d080905e40a1e45638fd868dccf Note that even though wrapped in MICROPY_CPYTHON_COMPAT, it is not fully compatible because the modifications to the dictionary do not propagate to the actual instance members. 2015-11-29T14:25:35+00:00 Damien George damien.p.george@gmail.com 2015-11-27T17:01:44+00:00 urn:sha1:999cedb90ff0827cdb9dfe0e4faa6ebc1739d271 This allows the mp_obj_t type to be configured to something other than a pointer-sized primitive type. This patch also includes additional changes to allow the code to compile when sizeof(mp_uint_t) != sizeof(void*), such as using size_t instead of mp_uint_t, and various casts. 2015-06-13T22:36:30+00:00 Damien George damien.p.george@gmail.com 2015-06-13T21:00:10+00:00 urn:sha1:c5029bcbf37fd1a3fb145d9fa9e4a5094478f17b 2015-05-12T22:05:53+00:00 Damien George damien.p.george@gmail.com 2015-05-12T22:05:53+00:00 urn:sha1:c50772d19fe2804a6d0258f89dd9967d3b516fd3 mp_obj_get_int_truncated will raise a TypeError if the argument is not an integral type. Use mp_obj_int_get_truncated only when you know the argument is a small or big int. 2015-05-12T21:46:02+00:00 Damien George damien.p.george@gmail.com 2015-05-11T12:25:19+00:00 urn:sha1:c2a4e4effc81d8ab21bb014e34355643e5ca0da2 Hashing is now done using mp_unary_op function with MP_UNARY_OP_HASH as the operator argument. Hashing for int, str and bytes still go via fast-path in mp_unary_op since they are the most common objects which need to be hashed. This lead to quite a bit of code cleanup, and should be more efficient if anything. It saves 176 bytes code space on Thumb2, and 360 bytes on x86. The only loss is that the error message "unhashable type" is now the more generic "unsupported type for __hash__". 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. 2015-04-16T14:30:16+00:00 Damien George damien.p.george@gmail.com 2015-04-11T12:03:37+00:00 urn:sha1:044c473de203b4dbe93874813b430fb6336db2b2 2015-04-16T14:30:16+00:00 Damien George damien.p.george@gmail.com 2015-04-09T22:56:15+00:00 urn:sha1:7f9d1d6ab923096582622b700bedb6a571518eac Previous to this patch the printing mechanism was a bit of a tangled mess. This patch attempts to consolidate printing into one interface. All (non-debug) printing now uses the mp_print* family of functions, mainly mp_printf. All these functions take an mp_print_t structure as their first argument, and this structure defines the printing backend through the "print_strn" function of said structure. Printing from the uPy core can reach the platform-defined print code via two paths: either through mp_sys_stdout_obj (defined pert port) in conjunction with mp_stream_write; or through the mp_plat_print structure which uses the MP_PLAT_PRINT_STRN macro to define how string are printed on the platform. The former is only used when MICROPY_PY_IO is defined. With this new scheme printing is generally more efficient (less layers to go through, less arguments to pass), and, given an mp_print_t* structure, one can call mp_print_str for efficiency instead of mp_printf("%s", ...). Code size is also reduced by around 200 bytes on Thumb2 archs.
