2025-04-21py/objstr: Fix handling of OP_MODULO with namedtuple.Yoctopuce dev
This fix handles attrtuple as well, eg. os.uname(). A test case has been added in basics/attrtuple2.py. Fixes issue #16969. Signed-off-by: Yoctopuce dev <dev@yoctopuce.com>
2024-03-07all: Remove the "STATIC" macro and just use "static" instead.Angus Gratton
The STATIC macro was introduced a very long time ago in commit d5df6cd44a433d6253a61cb0f987835fbc06b2de. The original reason for this was to have the option to define it to nothing so that all static functions become global functions and therefore visible to certain debug tools, so one could do function size comparison and other things. This STATIC feature is rarely (if ever) used. And with the use of LTO and heavy inline optimisation, analysing the size of individual functions when they are not static is not a good representation of the size of code when fully optimised. So the macro does not have much use and it's simpler to just remove it. Then you know exactly what it's doing. For example, newcomers don't have to learn what the STATIC macro is and why it exists. Reading the code is also less "loud" with a lowercase static. One other minor point in favour of removing it, is that it stops bugs with `STATIC inline`, which should always be `static inline`. Methodology for this commit was: 1) git ls-files | egrep '\.[ch]$' | \ xargs sed -Ei "s/(^| )STATIC($| )/\1static\2/" 2) Do some manual cleanup in the diff by searching for the word STATIC in comments and changing those back. 3) "git-grep STATIC docs/", manually fixed those cases. 4) "rg -t python STATIC", manually fixed codegen lines that used STATIC.

2024-02-19py/obj: Change sizeof to offsetof in mp_obj_malloc_var macro.Damien George
Following b6a977848407a4ced45d118cf926bd915cc89dfb, to properly calculate the size of the variable-length allocation. Signed-off-by: Damien George <damien@micropython.org>
2023-11-03py/misc: Change sizeof to offsetof for variable-length alloc.Jim Mussared
This fixes the case where e.g. struct foo_t { mp_obj_t x; uint16_t y; char buf[]; }; will have `sizeof(struct foo_t)==8`, but `offsetof(struct foo_t, buf)==6`. When computing the size to allocate for `m_new_obj_var` we need to use offsetof to avoid over-allocating. This is important especially when it might cause it to spill over into another GC block.

2022-09-19py/obj: Convert make_new into a mp_obj_type_t slot.Jim Mussared
Instead of being an explicit field, it's now a slot like all the other methods. This is a marginal code size improvement because most types have a make_new (100/138 on PYBV11), however it improves consistency in how types are declared, removing the special case for make_new.

2022-09-19py/obj: Merge getiter and iternext mp_obj_type_t slots.Jim Mussared
The goal here is to remove a slot (making way to turn make_new into a slot) as well as reduce code size by the ~40 references to mp_identity_getiter and mp_stream_unbuffered_iter. This introduces two new type flags: - MP_TYPE_FLAG_ITER_IS_ITERNEXT: This means that the "iter" slot in the type is "iternext", and should use the identity getiter. - MP_TYPE_FLAG_ITER_IS_CUSTOM: This means that the "iter" slot is a pointer to a mp_getiter_iternext_custom_t instance, which then defines both getiter and iternext. And a third flag that is the OR of both, MP_TYPE_FLAG_ITER_IS_STREAM: This means that the type should use the identity getiter, and mp_stream_unbuffered_iter as iternext. Finally, MP_TYPE_FLAG_ITER_IS_GETITER is defined as a no-op flag to give the default case where "iter" is "getiter". Signed-off-by: Jim Mussared <jim.mussared@gmail.com>

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>
2021-08-07extmod/modujson: Add support for dump/dumps separators keyword-argument.Peter Züger
Optionally enabled via MICROPY_PY_UJSON_SEPARATORS. Enabled by default. For dump, make sure mp_get_stream_raise is called after mod_ujson_separators since CPython does it in this order (if both separators and stream are invalid, separators will raise an exception first). Add separators argument in the docs as well. Signed-off-by: Peter Züger <zueger.peter@icloud.com> Signed-off-by: Damien George <damien@micropython.org>

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.
2020-02-21py/objtype: Allow mp_instance_cast_to_native_base to take native obj.Damien George
And rename it to mp_obj_cast_to_native_base() to indicate this. This allows users of this function to easily support native and native-subclass objects in the same way (by just passing the object through this function).
2020-02-20py/objtuple: Remove code that handles tuple-subclass equality test.Damien George
Since commit 3aab54bf434e7f025a91ea05052f1bac439fad8c this piece of code is no longer needed because the top-level function mp_obj_equal_not_equal() now handles the case of user types, and will never call tuple's binary_op function with MP_BINARY_OP_EQUAL and a non-tuple on the RHS.
2020-01-09py: Make mp_obj_get_type() return a const ptr to mp_obj_type_t.Damien George
Most types are in rodata/ROM, and mp_obj_base_t.type is a constant pointer, so enforce this const-ness throughout the code base. If a type ever needs to be modified (eg a user type) then a simple cast can be used.
2019-08-31py/objtuple: Allow compatible subclasses of tuple in mp_obj_tuple_get.Jeff Epler
As part of this patch a private macro mp_obj_is_tuple_compatible is introduced to encapsulate the check, which is used in two locations. Fixes #5005.
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.
2019-02-06py: Update my copyright info on some files.Paul Sokolovsky
Based on git history.
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.
2017-09-06py/objtuple: Properly implement comparison with incompatible types.Paul Sokolovsky
Should raise TypeError, unless it's (in)equality comparison.
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.
2017-08-13all: 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.
2017-08-09py/objtuple: Allow to use inplace-multiplication operator on tuples.Damien George
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.
2017-04-05py/objtuple: Add support for inplace add (same as normal add).Damien George
2017-03-29py: Convert mp_uint_t to size_t for tuple/list accessors.Damien George
This patch changes mp_uint_t to size_t for the len argument of the following public facing C functions: mp_obj_tuple_get mp_obj_list_get mp_obj_get_array These functions take a pointer to the len argument (to be filled in by the function) and callers of these functions should update their code so the type of len is changed to size_t. For ports that don't use nan-boxing there should be no change in generate code because the size of the type remains the same (word sized), and in a lot of cases there won't even be a compiler warning if the type remains as mp_uint_t. The reason for this change is to standardise on the use of size_t for variables that count memory (or memory related) sizes/lengths. It helps builds that use nan-boxing.
2017-03-23py: Use size_t as len argument and return type of mp_get_index.Damien George
These values are used to compute memory addresses and so size_t is the more appropriate type to use.
2017-02-16py: De-optimise some uses of mp_getiter, so they don't use the C stack.Damien George
In these cases the heap is anyway used to create a new object so no real need to use the C stack for iterating. It saves a few bytes of code size.
2017-02-16py: Add iter_buf to getiter type method.Damien George
Allows to iterate over the following without allocating on the heap: - tuple - list - string, bytes - bytearray, array - dict (not dict.keys, dict.values, dict.items) - set, frozenset Allows to call the following without heap memory: - all, any, min, max, sum TODO: still need to allocate stack memory in bytecode for iter_buf.
2017-02-16py/objtuple: Convert mp_uint_t to size_t where appropriate.Damien George
2016-08-14py/objtuple: In tuple_cmp_helper, use mp_check_self instead of raising.Damien George
Only tuple, namedtuple and attrtuple use the tuple_cmp_helper function, and they all have getiter=mp_obj_tuple_getiter, so the check here is only to ensure that the self object is consistent. Hence use mp_check_self.
2016-08-12py: Get rid of assert() in method argument checking functions.Paul Sokolovsky
Checks for number of args removes where guaranteed by function descriptor, self checking is replaced with mp_check_self(). In few cases, exception is raised instead of assert.
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 signature of builtin funs that take variable or kw args.Damien George
With this patch the n_args parameter is changed type from mp_uint_t to size_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.
2016-01-03py: Use polymorphic iterator type where possible to reduce code size.Damien George
Only types whose iterator instances still fit in 4 machine words have been changed to use the polymorphic iterator. Reduces Thumb2 arch code size by 264 bytes.
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
2015-10-11py: Rename MP_BOOL() to mp_obj_new_bool() for consistency in naming.Paul Sokolovsky
2015-09-03py: Use mp_not_implemented consistently for not implemented features.Damien George
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__".
2015-04-16py: 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.
2015-02-27py: Use m_{new,renew,del} consistently.Damien George
This is so all memory requests go through the same interface.
2015-01-20py, unix: Allow to compile with -Wunused-parameter.Damien George

2015-01-01py: Move to guarded includes, everywhere in py/ core.Damien George
Addresses issue #1022.
2014-09-17py: Add native json printing using existing print framework.Damien George
Also add start of ujson module with dumps implemented. Enabled in unix and stmhal ports. Test passes on both.
