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. 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. 2015-04-04T19:15:31+00:00 Damien George damien.p.george@gmail.com 2015-04-04T19:15:31+00:00 urn:sha1:56606f3475dc3feecc3fde2fef6cd42fb5ee2bac Without this patch deleting a property, or class with descriptor, will call the setter with a NULL value and lead to a crash. 2015-04-04T14:53:11+00:00 Damien George damien.p.george@gmail.com 2015-04-04T14:53:11+00:00 urn:sha1:2801e6fad8b8b3ecdd9c8bc58f9515ff66eca46c 2015-03-30T22:05:03+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2015-03-29T23:29:59+00:00 urn:sha1:1bc534247cfe585afeba41b58b25a21af158ae4e Conditional on MICROPY_PY_ALL_SPECIAL_METHODS.
