* py: Remove 5 TODOs in emitbc, objrange and repl.Damien George2024-07-18
| | | | | | | | | | | | | | | | These TODOs don't need to be done: - Calling functions with keyword arguments is less common than without them, so adding an extra byte overhead to all calls regardless of whether they use keywords or not would overall increase generated bytecode size. - Restricting `range` objects to machine-sized ints has been adequate for a long time now, so no need to change that and make it more complicated and slower. - Printing spaces in tab completion does not need to be optimised.

* all: Remove the "STATIC" macro and just use "static" instead.Angus Gratton2024-03-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. This work was funded through GitHub Sponsors. Signed-off-by: Angus Gratton <angus@redyak.com.au>
* py/obj: Convert make_new into a mp_obj_type_t slot.Jim Mussared2022-09-19
| | | | | | | | | | | 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.

* py/obj: Merge getiter and iternext mp_obj_type_t slots.Jim Mussared2022-09-19
| | | | | | | | | | | | | | | | | | | | | | 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>
* all: Fix #if inside MP_DEFINE_CONST_OBJ_TYPE for msvc.Jim Mussared2022-09-19
| | | | | | | | | | | | | | | | | | | | | | Changes: MP_DEFINE_CONST_OBJ_TYPE( ... #if FOO ... #endif ... ); to: MP_DEFINE_CONST_OBJ_TYPE( ... FOO_TYPE_ATTR ... ); Signed-off-by: Jim Mussared <jim.mussared@gmail.com>
* all: Make all mp_obj_type_t defs use MP_DEFINE_CONST_OBJ_TYPE.Jim Mussared2022-09-19

* all: Use mp_obj_malloc everywhere it's applicable.Jim Mussared2022-05-03
| | | | | | | | | | | | | | | 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>

* py: Downcase all MP_OBJ_IS_xxx macros to make a more consistent C API.Damien George2019-02-12
| | | | | | | | | | | | | | | | | | | | | 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.
* py/objrange: Implement (in)equality comparison between range objects.Damien George2018-02-14
| | | | | | | | | | | | This feature is not often used so is guarded by the config option MICROPY_PY_BUILTINS_RANGE_BINOP which is disabled by default. With this option disabled MicroPython will always return false when comparing two range objects for equality (unless they are exactly the same object instance). This does not match CPython so if (in)equality between range objects is needed then this option should be enabled. Enabling this option costs between 100 and 200 bytes of code space depending on the machine architecture.
* all: Remove inclusion of internal py header files.Damien George2017-10-04
| | | | | | | | | | | | | | | | 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.
* all: Convert mp_uint_t to mp_unary_op_t/mp_binary_op_t where appropriateDamien George2017-08-29
| | | | | | | 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.
* all: Use the name MicroPython consistently in commentsAlexander Steffen2017-07-31
| | | | | There were several different spellings of MicroPython present in comments, when there should be only one.
* py/objrange: Fix slicing of range when step of slice is negative.Damien George2017-05-18
|
* py: Raise a ValueError if range() step is zero.Damien George2017-04-05
| | | | | Following CPython. Otherwise one gets either an infinite loop (if code is optimised by the uPy compiler) or possibly a divide-by-zero CPU exception.
* py: Use size_t as len argument and return type of mp_get_index.Damien George2017-03-23
| | | | | These values are used to compute memory addresses and so size_t is the more appropriate type to use.
* py: Add iter_buf to getiter type method.Damien George2017-02-16
| | | | | | | | | | | | | | | 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.
* py: Change first arg of type.make_new from mp_obj_t to mp_obj_type_t*.Damien George2016-01-11
| | | | | | | | 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.
* py: Change type of .make_new and .call args: mp_uint_t becomes size_t.Damien George2016-01-11
| | | | | | | 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.
* py: Wrap all obj-ptr conversions in MP_OBJ_TO_PTR/MP_OBJ_FROM_PTR.Damien George2015-11-29
| | | | | | | | | 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.
* py: Rename MP_BOOL() to mp_obj_new_bool() for consistency in naming.Paul Sokolovsky2015-10-11

* py: Overhaul and simplify printf/pfenv mechanism.Damien George2015-04-16
| | | | | | | | | | | | | | | | | | | | | | 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.
* py: Combine load_attr and store_attr type methods into one (attr).Damien George2015-04-11
| | | | | | 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.

* py: Convert [u]int to mp_[u]int_t where appropriate.Damien George2014-10-03
| | | | Addressing issue #50.
* Change some parts of the core API to use mp_uint_t instead of uint/int.Damien George2014-08-30
| | | | Addressing issue #50, still some way to go yet.
* py: Improve range: add len, subscr, proper print.Damien George2014-08-12
| | | | | | | | Can now index ranges with integers and slices, and reverse ranges (although reversing is not very efficient). Not sure how useful this stuff is, but gets us closer to having all of Python's builtins.
* Rename machine_(u)int_t to mp_(u)int_t.Damien George2014-07-03
| | | | See discussion in issue #50.
* Add license header to (almost) all files.Damien George2014-05-03
| | | | | | | 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/.
* py, unix: Make "mpconfig.h" be first included, as other headers depend on it.Paul Sokolovsky2014-05-02
| | | | Specifically, nlr.h does.
* py: Add arg checking helper functions.Damien George2014-04-20
| | | | | | | These are to assist in writing native C functions that take positional and keyword arguments. mp_arg_check_num is for just checking the number of arguments is correct. mp_arg_parse_all is for parsing positional and keyword arguments with default values.
* py: Add MP_OBJ_STOP_ITERATION and make good use of it.Damien George2014-04-17
| | | | | Also make consistent use of MP_OBJ_NOT_SUPPORTED and MP_OBJ_NULL. This helps a lot in debugging and understanding of function API.
* py: Make built-in 'range' a class.Damien George2014-04-17
| | | | Addresses issue #487.
* py: Fix "TypeError: 'iterator' object is not iterable", doh.Paul Sokolovsky2014-03-30

* py: Replace mp_const_stop_iteration object with MP_OBJ_NULL.Damien George2014-03-26
|
* py: Clean up includes.xbe2014-03-17
| | | | Remove unnecessary includes. Add includes that improve portability.
* Implement proper exception type hierarchy.Damien George2014-02-15
| | | | | | | | | | | | | | Each built-in exception is now a type, with base type BaseException. C exceptions are created by passing a pointer to the exception type to make an instance of. When raising an exception from the VM, an instance is created automatically if an exception type is raised (as opposed to an exception instance). Exception matching (RT_BINARY_OP_EXCEPTION_MATCH) is now proper. Handling of parse error changed to match new exceptions. mp_const_type renamed to mp_type_type for consistency.
* Change mp_obj_type_t.name from const char * to qstr.Damien George2014-02-15
| | | | | | Ultimately all static strings should be qstr. This entry in the type structure is only used for printing error messages (to tell the type of the bad argument), and printing objects that don't supply a .print method.
* Replace global "static" -> "STATIC", to allow "analysis builds". Part 1.Paul Sokolovsky2014-02-12
| | | | | | | | Some tools do not support local/static symbols (one example is GNU ld map file). Exposing all functions will allow to do detailed size comparisons, etc. Also, added bunch of statics where they were missing, and replaced few identity functions with global mp_identity().
* Revamp qstrs: they now include length and hash.Damien George2014-01-21
| | | | | Can now have null bytes in strings. Can define ROM qstrs per port using qstrdefsport.h

* Convert many object types structs to use C99 tagged initializer syntax.Paul Sokolovsky2014-01-05

* Convert Python types to proper Python type hierarchy.Damien George2014-01-04
| | | | Now much more inline with how CPython does types.
* Change object representation from 1 big union to individual structs.Damien2013-12-21
A big change. Micro Python objects are allocated as individual structs with the first element being a pointer to the type information (which is itself an object). This scheme follows CPython. Much more flexible, not necessarily slower, uses same heap memory, and can allocate objects statically. Also change name prefix, from py_ to mp_ (mp for Micro Python).
