* 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: De-optimise some uses of mp_getiter, so they don't use the C stack.Damien George2017-02-16
| | | | | 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.
* 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/objset: Convert mp_uint_t to size_t where appropriate.Damien George2017-02-16
|
* py/objset: Fix inplace binary ops so frozensets are not modified.Damien George2017-02-03
|
* py/objset: Make inplace binary operators actually modify the set.Damien George2017-02-02
|
* py: Use mp_raise_msg helper function where appropriate.Damien George2016-10-17
| | | | | Saves the following number of bytes of code space: 176 for bare-arm, 352 for minimal, 272 for unix x86-64, 140 for stmhal, 120 for esp8266.
* py/objset: Ensure that use of frozenset.update raises an exception.Damien George2016-09-28
|
* py/objset: Use mp_check_self() to check args of set/frozenset methods.Damien George2016-09-28
| | | | | | | | | Following how other objects work, set/frozenset methods should use the mp_check_self() macro to check the type of the self argument, because in most cases this check can be a null operation. Saves about 100-180 bytes of code for builds with set and frozenset enabled.
* py: Get rid of assert() in method argument checking functions.Paul Sokolovsky2016-08-12
| | | | | | 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.
* 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 signature of builtin funs that take variable or kw args.Damien George2016-01-11
| | | | | With this patch the n_args parameter is changed type from mp_uint_t to size_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: Use polymorphic iterator type where possible to reduce code size.Damien George2016-01-03
| | | | | | | 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.
* 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: Add MP_ROM_* macros and mp_rom_* types and use them.Damien George2015-11-29
|
* py: Rename MP_BOOL() to mp_obj_new_bool() for consistency in naming.Paul Sokolovsky2015-10-11
|
* objset: frozensets are hashable.Paul Sokolovsky2015-08-28
|
* 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.

| | | | Part of code cleanup, towards resolving 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: Add option to disable set() object (enabled by default).Damien George2014-06-01
|
* Rename bultins config variables to MICROPY_PY_BUILTINS_*.Damien George2014-06-01
| | | | | | | | | | 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.
* Rename configuration variables controling Python features.Damien George2014-05-24
| | | | Now of the form MICROPY_PY_*. See issue #35.
* py: Rename MP_OBJ_NOT_SUPPORTED to MP_OBJ_NULL.Damien George2014-05-21
| | | | See issue #608 for justification.
* py: frozenset() creates an empty frozenset.Damien George2014-05-11
|
* py: Disable frozenset by default, enable on unix.Paul Sokolovsky2014-05-10
| | | | Takes 416 text bytes on x86.
* objset: Give up and implement frozenset.Paul Sokolovsky2014-05-10
| | | | Tired of patching CPython stdlib for it.
* py: Tidy up returning NULL which should be MP_OBJ_NOT_SUPPORTED.Damien George2014-05-10
|
* 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 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: Factor out impl of special methods for builtin types into opmethods.cPaul Sokolovsky2014-04-13
|
* objset: Implement __contains__() op-method.Paul Sokolovsky2014-04-13
|
* py: Remove useless implementations of NOT_EQUAL in binary_op's.Damien George2014-04-12
| | | | | | | 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).
* objset: Fix incorrect workaround against mp_set_init() munging alloc size.Paul Sokolovsky2014-04-07
| | | | | No longer needed after recent change which guarantees that mp_set_init() will allocate exact number of slots requested.
* py: Change module globals from mp_map_t* to mp_obj_dict_t*.Damien George2014-04-05
| | | | | | Towards addressing issue #424. Had a small increase to ROM usage (order 60 bytes).
* py: Change nlr_jump to nlr_raise, to aid in debugging.Damien George2014-04-05
| | | | | | This does not affect code size or performance when debugging turned off. To address issue #420.
* py: Fix delete operation on map/dict and set objects.Damien George2014-04-05
| | | | | | Hash table can now be completely full (ie now NULL entry) before a resize is triggered. Use sentinel value to indicate delete entry in the table.
* py: Fix "TypeError: 'iterator' object is not iterable", doh.Paul Sokolovsky2014-03-30
|
* Merge map.h into obj.h.Damien George2014-03-30
| | | | | | Pretty much everyone needs to include map.h, since it's such an integral part of the Micro Python object implementation. Thus, the definitions are now in obj.h instead. map.h is removed.
* Rename rt_* to mp_*.Damien George2014-03-30
| | | | | | | Mostly just a global search and replace. Except rt_is_true which becomes mp_obj_is_true. Still would like to tidy up some of the names, but this will do for now.
* py: Rename old const type objects to mp_type_* for consistency.Damien George2014-03-29
|
* Remove mp_obj_type_t.methods entry and use .locals_dict instead.Damien George2014-03-26
| | | | | | | | | | | | | | | | | | | | | | Originally, .methods was used for methods in a ROM class, and locals_dict for methods in a user-created class. That distinction is unnecessary, and we can use locals_dict for ROM classes now that we have ROMable maps. This removes an entry in the bloated mp_obj_type_t struct, saving a word for each ROM object and each RAM object. ROM objects that have a methods table (now a locals_dict) need an extra word in total (removed the methods pointer (1 word), no longer need the sentinel (2 words), but now need an mp_obj_dict_t wrapper (4 words)). But RAM objects save a word because they never used the methods entry. Overall the ROM usage is down by a few hundred bytes, and RAM usage is down 1 word per user-defined type/class. There is less code (no need to check 2 tables), and now consistent with the way ROM modules have their tables initialised. Efficiency is very close to equivaluent.
