CircuitPython - a Python implementation for teaching coding with microcontrollers https://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=v1.4.5 2015-07-02T09:53:08+00:00 2015-07-02T09:53:08+00:00 Daniel Campora daniel@wipy.io 2015-06-29T20:45:39+00:00 urn:sha1:077812b2abe3f5e5325194f9694dad7eb38186dd The TimeoutError is useful for some modules, specially the the socket module. TimeoutError can then be alised to socket.timeout and then Python code can differentiate between socket.error and socket.timeout. 2015-06-13T22:36:30+00:00 Damien George damien.p.george@gmail.com 2015-06-13T21:00:10+00:00 urn:sha1:c5029bcbf37fd1a3fb145d9fa9e4a5094478f17b 2015-05-17T16:42:04+00:00 Kaspar Schleiser kaspar@schleiser.de 2015-05-09T19:46:29+00:00 urn:sha1:cf5112b26f3e6e96480234d50b2c781663d971c2 ISO C forbids conversion between function pointers and void*, gcc -pedantic triggers a warning. 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__". 2015-05-05T19:18:07+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2015-05-05T19:18:07+00:00 urn:sha1:76677270218fb5732296e4fe1a0acbe05c8f818c Having NotImplemented as MP_OBJ_SENTINEL turned out to be problematic (it needs to be checked for in a lot of places, otherwise it'll crash as would pass MP_OBJ_IS_OBJ()), so made a proper singleton value like Ellipsis, both of them sharing the same type. 2015-04-20T13:29:31+00:00 Damien George damien.p.george@gmail.com 2015-04-20T13:29:31+00:00 urn:sha1:c8b60f013b9d624a74ad502460f2bc7d00c39644 This fixes a long standing problem that viper code generation gave terrible error messages, and actually no errors on pyboard where assertions are disabled. Now all compile-time errors are raised as proper Python exceptions, and are of type ViperTypeError. Addresses issue #940. 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. 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. 2015-04-07T21:43:28+00:00 Damien George damien.p.george@gmail.com 2015-04-06T21:38:53+00:00 urn:sha1:9988618e0e0f5c319e31b135d993e22efb593093 This patch gets full function argument passing working with native emitter. Includes named args, keyword args, default args, var args and var keyword args. Fully Python compliant. It reuses the bytecode mp_setup_code_state function to do all the hard work. This function is slightly adjusted to accommodate native calls, and the native emitter is forced a bit to emit similar prelude and code-info as bytecode.
