2015-04-04py: Implement delete for property and descriptors.Damien George
Without this patch deleting a property, or class with descriptor, will call the setter with a NULL value and lead to a crash.
2015-04-04py: Some trivial cosmetic changes, for code style consistency.Damien George
2015-03-31objtype: Add special unary methods __pos__, __neg__, __invert__.Paul Sokolovsky
Conditional on MICROPY_PY_ALL_SPECIAL_METHODS.
2015-03-26py: Add optional support for descriptors' __get__ and __set__ methods.stijn
Disabled by default. Enabled on unix and windows ports.
2015-03-21py: Combine duplicated code that converts members from a lookup.Damien George
Despite initial guess, this code factoring does not hamper performance. In fact it seems to improve speed by a little: running pystone(1.2) on pyboard (which gives a very stable result) this patch takes pystones from 1729.51 up to 1742.16. Also, pystones on x64 increase by around the same proportion (but it's much noisier). Taking a look at the generated machine code, stack usage with this patch is unchanged, and call is tail-optimised with all arguments in registers. Code size decreases by about 50 bytes on Thumb2 archs.
2015-03-20objtype: More comment clarification for attribute lookup.Paul Sokolovsky
2015-03-17objtype: Clarify comment why we call mp_load_method_maybe() for native sub-obj.Paul Sokolovsky
2015-03-16objtype: Refactor dealing with native sub-objects for clarity.Paul Sokolovsky
2015-03-16objtype: mp_obj_class_lookup: Remove implausible condition.Paul Sokolovsky
We already have branch for lookup->is_type == true, so here it's guaranteed to be false.
2015-03-16objtype: Clarify comment for mp_obj_class_lookup().Paul Sokolovsky
2015-03-16objtype: Clarify code by consistently using common subexpression.Paul Sokolovsky
2015-02-22py: Add few more special methods.Paul Sokolovsky
2015-02-15py: Simplify and remove redundant code for __iter__ method lookup.Damien George
2015-02-14py: Cleanup duplication in instance_is_callable/instance_call.stijn
2015-02-09py: Don't unnecessarily create a bound method.Damien George
2015-02-09py: Allow subclass of native object to delegate to the native buffer_p.Damien George
Addresses issue #1109.
2015-02-08py: Fix instance lookup, since object is not a real type.Damien George
2015-01-31py: Add MICROPY_PY_ALL_SPECIAL_METHODS and __iadd__ special method under it.Paul Sokolovsky
2015-01-27py: Specify unary/binary op name in TypeError error message.Damien George
Eg, "() + 1" now tells you that __add__ is not supported for tuple and int types (before it just said the generic "binary operator"). We reuse the table of names for slot lookup because it would be a waste of code space to store the pretty name for each operator.
2015-01-20py: Use mp_arg_check_num in some _make_new functions.Damien George
Reduces stmhal code size by about 250 bytes.
2015-01-20py, unix: Allow to compile with -Wunused-parameter.Damien George
See issue #699.
2015-01-11py: Remove unnecessary BINARY_OP_EQUAL code that just checks pointers.Damien George
Previous patch c38dc3ccc76d1a9bf867704f43ea5d15da3fea7b allowed any object to be compared with any other, using pointer comparison for a fallback. As such, existing code which checked for this case is no longer needed.
2015-01-08tests: Add test for when instance member overrides class member.Damien George
2015-01-07py: Add option to cache map lookup results in bytecode.Damien George
This is a simple optimisation inspired by JITing technology: we cache in the bytecode (using 1 byte) the offset of the last successful lookup in a map. This allows us next time round to check in that location in the hash table (mp_map_t) for the desired entry, and if it's there use that entry straight away. Otherwise fallback to a normal map lookup. Works for LOAD_NAME, LOAD_GLOBAL, LOAD_ATTR and STORE_ATTR opcodes. On a few tests it gives >90% cache hit and greatly improves speed of code. Disabled by default. Enabled for unix and stmhal ports.
2015-01-01py: Move to guarded includes, everywhere in py/ core.Damien George
Addresses issue #1022.
2014-12-28showbc: Print operation mnemonic in BINARY_OP.Paul Sokolovsky
2014-11-06py: Use shorter, static error msgs when ERROR_REPORTING_TERSE enabled.Damien George
Going from MICROPY_ERROR_REPORTING_NORMAL to MICROPY_ERROR_REPORTING_TERSE now saves 2020 bytes ROM for ARM Thumb2, and 2200 bytes ROM for 32-bit x86. This is about a 2.5% code size reduction for bare-arm.
2014-11-05py: Fix some macros defines; cleanup some includes.Damien George
2014-11-03py: Explicitly set uninitialised struct member to false.Damien George
Uninitialised struct members get a default value of 0/false, so this is not strictly needed. But it actually decreases code size because when all members are initialised the compiler doesn't need to insert a call to memset to clear everything. In other words, setting 1 extra member to 0 uses less code than calling memset. ROM savings in bytes: 32-bit unix: 100; bare-arm: 44; stmhal: 52.
2014-11-03py: Fix builtin callable so it checks user-defined instances correctly.Damien George
Addresses issue #953.
2014-10-23py: Use MP_OBJ_NULL instead of NULL in a few places.Damien George
2014-08-30py: Make tuple and list use mp_int_t/mp_uint_t.Damien George
Part of code cleanup, to resolve issue #50.
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.
2014-08-26py: Add dispatch for user defined ==, >, <=, >=.Damien George
Addresses issue #827.
2014-08-24py: Fix bug where GC collected native/viper/asm function data.Damien George
Because (for Thumb) a function pointer has the LSB set, pointers to dynamic functions in RAM (eg native, viper or asm functions) were not being traced by the GC. This patch is a comprehensive fix for this. Addresses issue #820.
2014-07-05py: Automatically ake __new__ a staticmethod.Damien George
Addresses issue #622.
2014-07-03Rename machine_(u)int_t to mp_(u)int_t.Damien George
See discussion in issue #50.
2014-06-10py: Implement __contains__ special method.Damien George
2014-06-08objtype: Fix passing of class param to inherited classmethods.Paul Sokolovsky
This is getting more and more tangled, but that's old news.
2014-06-08objtype: Optimize stack usage mp_obj_class_lookup().Paul Sokolovsky
As before, instead of pushing constant values on stack again and again, just pass around pointer to a structure.
2014-06-08objtype: Enable __lt__ method support for instances.Paul Sokolovsky
2014-06-06Change comments (mainly URLs) to no longer specifically say Python 3.3Chris Angelico
2014-06-03py: Allow tail call optimisation in mp_call_function_n_kw.Damien George
This saves 4 words of stack space per Python call.
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.
2014-05-24Rename configuration variables controling Python features.Damien George
Now of the form MICROPY_PY_*. See issue #35.
2014-05-22py: Initial attempts to actually allow implementing __new__ in Python.Paul Sokolovsky
Caveat is that __new__ should recurse to base class __new__, and ultimately, object.__new__ is what handles instance allocation.
2014-05-21objtype: super: Fall back to "object" lookup as last resort.Paul Sokolovsky
Also, define object.__init__() (semantically empty, purely CPython compat measure). Addresses #520.
2014-05-21objtype: super: Add stop condition for looking up in base types.Paul Sokolovsky
2014-05-21py: Rename MP_OBJ_NOT_SUPPORTED to MP_OBJ_NULL.Damien George
See issue #608 for justification.
2014-05-19objtype: Separate __new__ and __init__ methods.Paul Sokolovsky
Now schedule is: for native types, we call ->make_new() C-level method, which should perform actions of __new__ and __init__ (note that this is not compliant, but is efficient), but for user types, __new__ and __init__ are called as expected. Also, make sure we convert scalar attribute value to a bound-pair tight in mp_obj_class_lookup() method, which avoids converting it again and again in its callers.
