2020-11-11extmod/moductypes: Fix storing to (U)INT64 arrays on 32-bit archs.Damien George
Fixes issue #6583. Signed-off-by: Damien George <damien@micropython.org>
2020-10-22py, extmod: Introduce and use MP_FALLTHROUGH macro.Emil Renner Berthing
Newer GCC versions are able to warn about switch cases that fall through. This is usually a sign of a forgotten break statement, but in the few cases where a fall through is intended we annotate it with this macro to avoid the warning.
2020-06-24extmod/moductypes: Use mp_obj_is_dict_or_ordereddict to simplify code.Damien George
Signed-off-by: Damien George <damien@micropython.org>
2020-04-23all: Format code to add space after C++-style comment start.stijn
Note: the uncrustify configuration is explicitly set to 'add' instead of 'force' in order not to alter the comments which use extra spaces after // as a means of indenting text for clarity.
2020-04-18all: Fix implicit conversion from double to float.stijn
These are found when building with -Wfloat-conversion.
2020-04-18all: Fix implicit floating point promotion.stijn
Initially some of these were found building the unix coverage variant on MacOS because that build uses clang and has -Wdouble-promotion enabled, and clang performs more vigorous promotion checks than gcc. Additionally the codebase has been compiled with clang and msvc (the latter with warning level 3), and with MICROPY_FLOAT_IMPL_FLOAT to find the rest of the conversions. Fixes are implemented either as explicit casts, or by using the correct type, or by using one of the utility functions to handle floating point casting; these have been moved from nativeglue.c to the public API.
2020-04-18Revert "all: Fix implicit casts of float/double, and signed comparison."stijn
This reverts commit a2110bd3fca59df8b16a2b5fe4645a4af30b06ed. There's nothing inherently wrong with it, but upcoming commits will apply similar fixes in a slightly different way.
2020-04-13all: Clean up error strings to use lowercase and change cannot to can't.Damien George
Now that error string compression is supported it's more important to have consistent error string formatting (eg all lowercase English words, consistent contractions). This commit cleans up some of the strings to make them more consistent.
2020-04-05all: Use MP_ERROR_TEXT for all error messages.Jim Mussared
2020-03-30all: Fix implicit casts of float/double, and signed comparison.David Lechner
These were found by buiding the unix coverage variant on macOS (so clang compiler). Mostly, these are fixing implicit cast of float/double to mp_float_t which is one of those two and one mp_int_t to size_t fix for good measure.
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.
2019-11-05all: Convert nlr_raise(mp_obj_new_exception_msg(x)) to mp_raise_msg(x).Damien George
This helper function was added a while ago and these are the remaining cases to convert, to save a bit of code size.
2019-09-02py/modstruct: Fix struct.pack_into with unaligned offset of native type.Damien George
Following the same fix for unpack.
2019-09-02py/modstruct: Fix struct.unpack with unaligned offset of native type.Tom McDermott
With this patch alignment is done relative to the start of the buffer that is being unpacked, not the raw pointer value, as per CPython. Fixes issue #3314.
2019-02-12extmod: Convert legacy uppercase macro names to lowercase.Damien George
2018-12-10extmod/moductypes: Add aliases for native C types.Paul Sokolovsky
SHORT, INT, LONG, LONGLONG, and unsigned (U*) variants are being defined. This is done at compile using GCC-style predefined macros like __SIZEOF_INT__. If the compiler doesn't have such defines, no such types will be defined.
2018-12-10extmod/moductypes: Implement __int__ for PTR.Paul Sokolovsky
Allows to get address a pointer contains, as an integer.
2018-10-23extmod/moductypes: Make sizeof() accept "layout" parameter.Paul Sokolovsky
sizeof() can work in two ways: a) calculate size of already instantiated structure ("sizeof variable") - in this case we already no layout; b) size of structure decsription ("sizeof type"). In the latter case, LAYOUT_NATIVE was assumed, but there should possibility to calculate size for other layouts too. So, with this patch, there're now 2 forms: uctypes.sizeof(struct) uctypes.sizeof(struct_desc, layout)
2018-10-13extmod/moductypes: Accept OrderedDict as a structure description.Paul Sokolovsky
Using OrderedDict (i.e. stable order of fields) would for example allow to automatically calculate field offsets in structures.
2018-10-05extmod/moductypes: Remove BITFIELD from aggregate types enum.Paul Sokolovsky
This value is unused. It was an artifact of early draft design, but bitfields were optimized to use scalar one-word encoding, to allow compact encoding of typical multiple bitfields in MCU control registers.
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.
2017-08-13all: Raise exceptions via mp_raise_XXXJavier Candeira
- Changed: ValueError, TypeError, NotImplementedError - OSError invocations unchanged, because the corresponding utility function takes ints, not strings like the long form invocation. - OverflowError, IndexError and RuntimeError etc. not changed for now until we decide whether to add new utility functions.
2017-08-02py,extmod,stmhal: Use "static inline" for funcs that should be inline.Damien George
"STATIC inline" can expand to "inline" if STATIC is defined to nothing, and this case can lead to link errors.
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.
2017-04-21extmod/moductypes: Fix bigint handling for 32-bit ports.Paul Sokolovsky
2016-09-21extmod/uctypes: Allow full 32-bit address range.Stefan Agner
Use mp_obj_int_get_truncated to allow the full 32-bit address range as first parameter.
2016-09-22all: Remove 'name' member from mp_obj_module_t struct.Damien George
One can instead lookup __name__ in the modules dict to get the value.
2016-03-19extmod/uctypes: Change param type from void* to byte*.Damien George
2016-03-19extmod/uctypes: Finish support for FLOAT32 and FLOAT64 types.Damien George
2016-03-19extmod/uctypes: Use mp_binary_get_val helper when extracting value.Damien George
It handles more cases than mp_binary_get_int.
2016-01-11py: Change first arg of type.make_new from mp_obj_t to mp_obj_type_t*.Damien George
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.
2016-01-11py: Change type of .make_new and .call args: mp_uint_t becomes size_t.Damien George
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.
2016-01-10extmod: Fix uctypes size calculation for bitfieldsDave Hylands
2016-01-03uctypes: Implement assignment for scalar arrayAntonin ENFRUN
2015-12-09extmod/moductypes: sizeof operation depends on layout type of structure.Paul Sokolovsky
Previously, sizeof() blindly assumed LAYOUT_NATIVE and tried to align size even for packed LAYOUT_LITTLE_ENDIAN & LAYOUT_BIG_ENDIAN. As sizeof() is implemented on a strucuture descriptor dictionary (not an structure object), resolving this required passing layout type around.
2015-12-04extmod/moductypes: set_aligned(): Handle INT64/UINT64.Paul Sokolovsky
2015-11-29py: Wrap all obj-ptr conversions in MP_OBJ_TO_PTR/MP_OBJ_FROM_PTR.Damien George
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.
2015-11-29py: Add MP_ROM_* macros and mp_rom_* types and use them.Damien George
2015-10-28extmod/moductypes: When dealing with UINT64, use mp_obj_new_int_from_ull().Paul Sokolovsky
Since we now have it.
2015-10-26extmod/moductypes: Implement buffer protocol.Paul Sokolovsky
This is required to write structures to files, pass to FFI functions, etc.
2015-06-06moductypes: Swap address and descriptor args in constructor.Paul Sokolovsky
Now address comes first, and args related to struct type are groupped next. Besides clear groupping, should help catch errors eagerly (e.g. forgetting to pass address will error out). Also, improve args number checking/reporting overall.
2015-04-16py: Overhaul and simplify printf/pfenv mechanism.Damien George
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.
2015-04-11py: Combine load_attr and store_attr type methods into one (attr).Damien George
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.
2015-01-20py, unix: Allow to compile with -Wunused-parameter.Damien George
See issue #699.
2015-01-12py, unix, lib: Allow to compile with -Wold-style-definition.Damien George
2015-01-01extmod: Prefix py/ for includes from py core directory.Damien George
2014-12-10py: Make functions static where appropriate.Damien George
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.
2014-11-29Use MP_DEFINE_CONST_DICT macro to define module dicts.Damien George
This is just a clean-up of the code. Generated code is exactly the same.
