2022-05-03all: Use mp_obj_malloc everywhere it's applicable.Jim Mussared
This replaces occurences of foo_t *foo = m_new_obj(foo_t); foo->base.type = &foo_type; with foo_t *foo = mp_obj_malloc(foo_t, &foo_type); Excludes any places where base is a sub-field or when new0/memset is used. Signed-off-by: Jim Mussared <jim.mussared@gmail.com>
2020-05-28py/modsys: Use consistent naming pattern for module-level const objects.David Lechner
This renames a few identifiers to follow the usual naming convention of mp_<module>_<name>. This makes them easier to find, e.g. when grep'ing.
2020-04-05all: Use MP_ERROR_TEXT for all error messages.Jim Mussared
2020-02-28all: Reformat C and Python source code with tools/codeformat.py.Damien George
This is run with uncrustify 0.70.1, and black 19.10b0.
2019-02-12py: Downcase all MP_OBJ_IS_xxx macros to make a more consistent C API.Damien George
These macros could in principle be (inline) functions so it makes sense to have them lower case, to match the other C API functions. The remaining macros that are upper case are: - MP_OBJ_TO_PTR, MP_OBJ_FROM_PTR - MP_OBJ_NEW_SMALL_INT, MP_OBJ_SMALL_INT_VALUE - MP_OBJ_NEW_QSTR, MP_OBJ_QSTR_VALUE - MP_OBJ_FUN_MAKE_SIG - MP_DECLARE_CONST_xxx - MP_DEFINE_CONST_xxx These must remain macros because they are used when defining const data (at least, MP_OBJ_NEW_SMALL_INT is so it makes sense to have MP_OBJ_SMALL_INT_VALUE also a macro). For those macros that have been made lower case, compatibility macros are provided for the old names so that users do not need to change their code immediately.
2018-09-20py: Shorten error messages by using contractions and some rewording.Damien George
2018-04-05py/objint: Simplify LHS arg type checking in int binary op functions.Damien George
The LHS passed to mp_obj_int_binary_op() will always be an integer, either a small int or a big int, so the test for this type doesn't need to include an "other, unsupported type" case.
2017-12-08py/objint_longlong: Check for zero division/modulo.Paul Sokolovsky
2017-10-04all: Remove inclusion of internal py header files.Damien George
Header files that are considered internal to the py core and should not normally be included directly are: py/nlr.h - internal nlr configuration and declarations py/bc0.h - contains bytecode macro definitions py/runtime0.h - contains basic runtime enums Instead, the top-level header files to include are one of: py/obj.h - includes runtime0.h and defines everything to use the mp_obj_t type py/runtime.h - includes mpstate.h and hence nlr.h, obj.h, runtime0.h, and defines everything to use the general runtime support functions Additional, specific headers (eg py/objlist.h) can be included if needed.
2017-09-18py/modbuiltins: Implement abs() by dispatching to MP_UNARY_OP_ABS.Paul Sokolovsky
This allows user classes to implement __abs__ special method, and saves code size (104 bytes for x86_64), even though during refactor, an issue was fixed and few optimizations were made: * abs() of minimum (negative) small int value is calculated properly. * objint_longlong and objint_mpz avoid allocating new object is the argument is already non-negative.
2017-08-29all: Convert mp_uint_t to mp_unary_op_t/mp_binary_op_t where appropriateDamien George
The unary-op/binary-op enums are already defined, and there are no arithmetic tricks used with these types, so it makes sense to use the correct enum type for arguments that take these values. It also reduces code size quite a bit for nan-boxing builds.
2017-07-31all: Use the name MicroPython consistently in commentsAlexander Steffen
There were several different spellings of MicroPython present in comments, when there should be only one.
2017-07-25py: Implement raising a big-int to a negative power.Damien George
Before this patch raising a big-int to a negative power would just return 0. Now it returns a floating-point number with the correct value.
2017-06-15all: Make more use of mp_raise_{msg,TypeError,ValueError} helpers.Damien George
2017-04-30py: Cleanup use of global DEBUG preprocessor definitionstijn
The standard preprocessor definition to differentiate debug and non-debug builds is NDEBUG, not DEBUG, so don't rely on the latter: - just delete the use of it in objint_longlong.c as it has been stale code for years anyway (since commit [c4029e5]): SUFFIX isn't used anywhere. - replace DEBUG with MICROPY_DEBUG_NLR in nlr.h: it is rarely used anymore so can be off by default
2017-04-04py/objint: Consolidate mp_obj_new_int_from_float to one implementation.Damien George
This reduces code duplication and allows to make mp_classify_fp_as_int static, which reduces code size.
2017-03-10py/objint_longlong: Implement mp_obj_int_from_bytes_impl().Paul Sokolovsky
This makes int.from_bytes() work for MICROPY_LONGINT_IMPL_LONGLONG.
2017-02-16py/objint: Convert mp_uint_t to size_t where appropriate.Damien George
2017-01-21py/objint_longlong: Add stub for mp_obj_int_from_bytes_impl().Paul Sokolovsky
To be implemented later.
2016-12-21py/objint: Rename mp_obj_int_as_float to mp_obj_int_as_float_impl.Damien George
And also simplify it to remove the check for small int. This can be done because this function is only ever called if the argument is not a small int.
2016-10-11py/objint: Use size_t for arguments that measure bytes/sizes.Damien George
2016-03-10py: Use MP_SMALL_INT_POSITIVE_MASK to check if uint fits in a small int.Damien George
Using the original WORD_MSBIT_HIGH-logic resulted in errors when the object model is not REPR_A or REPR_C.
2016-01-07py: Change mp_obj_int_is_positive to more general mp_obj_int_sign.Damien George
This function returns the sign (-1, 0 or 1) of the integer object.
2015-11-09py/objint_longlong: Instead of assert, throw OverflowError.Paul Sokolovsky
2015-10-11py: Rename MP_BOOL() to mp_obj_new_bool() for consistency in naming.Paul Sokolovsky
2015-05-12py: Convert hash API to use MP_UNARY_OP_HASH instead of ad-hoc function.Damien George
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__".
2015-04-25py: Implement power op for long-long implementation of bignum.Damien George
2015-04-25py: Support conversion of bignum to bytes.Damien George
This gets int.to_bytes working for bignum, and also struct.pack with 'q' and 'Q' args on 32-bit machines. Addresses issue #1155.
2015-03-14py: Fix builtin abs so it works for bools and bignum.Damien George
2015-01-24py: Use float-to-int classifications for mp_obj_new_int_from_float() functionsDavid Steinberg
2015-01-01py: Move to guarded includes, everywhere in py/ core.Damien George
Addresses issue #1022.
2014-12-30py: Partially fix float to int conversion.Paul Sokolovsky
This fixes conversion when float type has more mantissa bits than small int, and float value has small exponent. This is for example the case of 32-bit platform using doubles, and converting value of time.time(). Conversion of floats with larg exponnet is still not handled correctly.
2014-12-05py: Rename mp_obj_int_get to mp_obj_int_get_truncated; fix struct.pack.Damien George
mp_obj_int_get_truncated is used as a "fast path" int accessor that doesn't check for overflow and returns the int truncated to the machine word size, ie mp_int_t. Use mp_obj_int_get_truncated to fix struct.pack when packing maximum word sized values. Addresses issues #779 and #998.
2014-09-10py: Enable struct/binary-helper to parse q and Q sized ints.Damien George
Addresses issue #848.
2014-09-06py: Correctly set sys.maxsize value for 64-bit.Paul Sokolovsky
Type representing signed size doesn't have to be int, so use special value which defaults to SSIZE_MAX, but as it's not defined by C standard (but rather by POSIX), allow ports to set it.
2014-08-30Change some parts of the core API to use mp_uint_t instead of uint/int.Damien George
Addressing issue #50, still some way to go yet.
2014-07-24py: Make long ints hashable.Damien George
Addresses issue #765.
2014-07-03py: Implement sys.maxsize, standard way to check platform "bitness".Paul Sokolovsky
Implementing it as a static constant is a bit peculiar and require cooperation from long int implementation.
2014-07-03Rename machine_(u)int_t to mp_(u)int_t.Damien George
See discussion in issue #50.
2014-06-01Rename bultins config variables to MICROPY_PY_BUILTINS_*.Damien George
This renames: MICROPY_PY_FROZENSET -> MICROPY_PY_BUILTINS_FROZENSET MICROPY_PY_PROPERTY -> MICROPY_PY_BUILTINS_PROPERTY MICROPY_PY_SLICE -> MICROPY_PY_BUILTINS_SLICE MICROPY_ENABLE_FLOAT -> MICROPY_PY_BUILTINS_FLOAT See issue #35 for discussion.
2014-05-28py: Fix check of small-int overflow when parsing ints.Damien George
Also unifies use of SMALL_INT_FITS macro across parser and runtime.
2014-05-28py: Implement long int parsing in int(...).Damien George
Addresses issue #627.
2014-05-21py: Rename MP_OBJ_NOT_SUPPORTED to MP_OBJ_NULL.Damien George
See issue #608 for justification.
2014-05-17py: More const usage.Paul Sokolovsky
2014-05-13py, unix: Add copyright for modules I worked closely on.Paul Sokolovsky
2014-05-07py: Improve native emitter; now supports more opcodes.Damien George
2014-05-03Add license header to (almost) all files.Damien George
Blanket wide to all .c and .h files. Some files originating from ST are difficult to deal with (license wise) so it was left out of those. Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/.
2014-05-02py, unix: Make "mpconfig.h" be first included, as other headers depend on it.Paul Sokolovsky
Specifically, nlr.h does.
2014-04-17py: Add MP_OBJ_STOP_ITERATION and make good use of it.Damien George
Also make consistent use of MP_OBJ_NOT_SUPPORTED and MP_OBJ_NULL. This helps a lot in debugging and understanding of function API.
2014-04-12py: Remove useless implementations of NOT_EQUAL in binary_op's.Damien George
I'm pretty sure these are never reached, since NOT_EQUAL is always converted into EQUAL in mp_binary_op. No one should call type.binary_op directly, they should always go through mp_binary_op (or mp_obj_is_equal).
