Used in the converted CPython stdlib logging.Formatter class to handle overrriding a default converter method bound to a class variable. The method becomes bound when accessed from an instance of that class. I didn't investigate why CircuitPython turns it into a bound method. 2017-12-11T02:49:09+00:00 Damien George damien.p.george@gmail.com 2017-11-26T12:37:19+00:00 urn:sha1:1e5a33df413bbd8a8aa5bd880be445c684fc5506 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. 2016-11-21T22:33:55+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2016-11-21T22:33:55+00:00 urn:sha1:037e6912c60f4f05a3866d525392f9c76914d0f1 By refactoring and reusing code from objboundmeth. 2016-03-08T15:36:53+00:00 Damien George damien.p.george@gmail.com 2016-03-08T15:36:53+00:00 urn:sha1:dcdf8f2d1404c8a9b6fb91ae1b31c6b991a08017 If the heap is locked, or memory allocation fails, then calling a bound method will still succeed by allocating the argument state on the stack. The new code also allocates less stack than before if less than 4 arguments are passed. It's also a tiny bit smaller in code size. This was done as part of the ESA project. 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. 2015-11-29T14:25:35+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. 2015-04-16T14:30:16+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.
