* py: Fix iteration over map in 2 places.Damien George2014-12-21

* py: Allow builtins to be overridden.Damien George2014-12-09
| | | | | | | | | | | | | | This patch adds a configuration option (MICROPY_CAN_OVERRIDE_BUILTINS) which, when enabled, allows to override all names within the builtins module. A builtins override dict is created the first time the user assigns to a name in the builtins model, and then that dict is searched first on subsequent lookups. Note that this implementation doesn't allow deleting of names. This patch also does some refactoring of builtins code, creating the modbuiltins.c file. Addresses issue #959.
* py: Optimise lexer by exposing lexer type.Damien George2014-12-05
| | | | | | | | | mp_lexer_t type is exposed, mp_token_t type is removed, and simple lexer functions (like checking current token kind) are now inlined. This saves 784 bytes ROM on 32-bit unix, 348 bytes on stmhal, and 460 bytes on bare-arm. It also saves a tiny bit of RAM since mp_lexer_t is a bit smaller. Also will run a bit more efficiently.
* py: Use shorter, static error msgs when ERROR_REPORTING_TERSE enabled.Damien George2014-11-06
| | | | | | | | 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.
* py: Fix bug with right-shifting small ints by large amounts.Paul Sokolovsky2014-11-02
| | | | Undefined behavior in C, needs explicit check.
* py: Add mp_pending_exception global variable, for VM soft interrupt.Damien George2014-10-25
| | | | | | | | | | | This allows to implement KeyboardInterrupt on unix, and a much safer ctrl-C in stmhal port. First ctrl-C is a soft one, with hope that VM will notice it; second ctrl-C is a hard one that kills anything (for both unix and stmhal). One needs to check for a pending exception in the VM only for jump opcodes. Others can't produce an infinite loop (infinite recursion is caught by stack check).
* py: Implement compile builtin, enabled only on unix port.Damien George2014-10-25
| | | | | | | This should be pretty compliant with CPython, except perhaps for some corner cases to do with globals/locals context. Addresses issue #879.
* py: Factor out mp_obj_is_package() function.Paul Sokolovsky2014-10-25
|
* py: Use MP_OBJ_NULL instead of NULL in a few places.Damien George2014-10-23
|
* py: Add #if guard around gc-specific code.Damien George2014-10-09
|
* Allow real memory errors (from locked gc) to be reported with traceback.Dave Hylands2014-10-07
|
* py: Implement proper context save/restore for eval/exec; factor code.Damien George2014-10-05
| | | | | | | | | This has benefits all round: code factoring for parse/compile/execute, proper context save/restore for exec, allow to sepcify globals/locals for eval, and reduced ROM usage by >100 bytes on stmhal and unix. Also, the call to mp_parse_compile_execute is tail call optimised for the import code, so it doesn't increase stack memory usage.
* py: Change [u]int to mp_[u]int_t in qstr.[ch], and some other places.Damien George2014-10-03
| | | | This should pretty much resolve issue #50.
* py: Tidy up exception matching; allow matching of tuple of exceptions.Damien George2014-09-25
| | | | Addresses issue #864.
* py: For malloc and vstr functions, use size_t exclusively for int type.Damien George2014-09-25
| | | | | | It seems most sensible to use size_t for measuring "number of bytes" in malloc and vstr functions (since that's what size_t is for). We don't use mp_uint_t because malloc and vstr are not Micro Python specific.
* stmhal: Initialise stack pointer correctly.Damien George2014-09-23
| | | | | | | | | | | | | Stack is full descending and must be 8-byte aligned. It must start off pointing to just above the last byte of RAM. Previously, stack started pointed to last byte of RAM (eg 0x2001ffff) and so was not 8-byte aligned. This caused a bug in combination with alloca. This patch also updates some debug printing code. Addresses issue #872 (among many other undiscovered issues).
* py: Small simplifications in tuple and list accessors.Damien George2014-08-30

* py: Change uint to mp_uint_t in runtime.h, stackctrl.h, binary.h.Damien George2014-08-30
| | | | Part of code cleanup, working towards resolving issue #50.
* py: Change all uint to mp_uint_t in obj.h.Damien George2014-08-30
| | | | Part of code cleanup, working towards resolving issue #50.
* py: Make tuple and list use mp_int_t/mp_uint_t.Damien George2014-08-30
| | | | Part of code cleanup, to resolve issue #50.
* py: Move native glue code from runtime.c to new file nativeglue.c.v1.3.1Damien George2014-08-28
| | | | | | | | This way, the native glue code is only compiled if native code is enabled (which makes complete sense; thanks to Paul Sokolovsky for the idea). Should fix issue #834.
* py: Code clean-up in native emitter; improve thumb native calls.Damien George2014-08-16

* py: Viper can call functions with native types, and raise exceptions.Damien George2014-08-16
|
* py: Viper can now store to global.Damien George2014-08-15
|
* Put call to qstr_init and mp_init_emergency_exc_buf in mp_init.Damien George2014-08-04
| | | | | | | qstr_init is always called exactly before mp_init, so makes sense to just have mp_init call it. Similarly with mp_init_emergency_exception_buf. Doing this makes the ports simpler and less error prone (ie they can no longer forget to call these).
* Rename machine_(u)int_t to mp_(u)int_t.Damien George2014-07-03
| | | | See discussion in issue #50.
* stackctrl: Add "mp_" prefix.Paul Sokolovsky2014-07-01
|
* py: Move stack_ctrl_init() to mp_init().Paul Sokolovsky2014-06-27
| | | | | | As stack checking is enabled by default, ports which don't call stack_ctrl_init() are broken now (report RuntimeError on startup). Save them trouble and just init stack control framework in interpreter init.
* py: Separate MICROPY_PY_BUILTINS_COMPLEX from MICROPY_PY_BUILTINS_FLOAT.Paul Sokolovsky2014-06-20
| | | | | One thing is wanting to do 1 / 2 and get something else but 0, and quite another - doing rocket science ;-).
* Merge branch 'alloca' of github.com:marcusva/micropython into marcusva-allocaDamien George2014-06-08
|\
| * - FreeBSD provides alloca() via stdlib.h, in contrast to Linux and WindowsMarcus von Appen2014-06-07
| | | | | | | | - Move the includes for alloca() intp mpconfigport.h
* | py: Add generic mp_not_implemented() func to use instead of assert().Paul Sokolovsky2014-06-07
|/ | | | | | Benefits: won't crash baremetal targets, will provide Python source location when not implemented feature used (it will no longer provide C source location, but just grep for error message).
* Change comments (mainly URLs) to no longer specifically say Python 3.3Chris Angelico2014-06-06

* py: Allow tail call optimisation in mp_call_function_n_kw.Damien George2014-06-03
| | | | This saves 4 words of stack space per Python call.
* py: Instead of having "debug on" var, have "optimization level" var.Paul Sokolovsky2014-06-03
| | | | | This allows to have multiple "optimization" levels (CPython has two (-OO removes docstrings), we can have more).
* py: Fix configurability of builtin slice.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.
* py: Fix check of small-int overflow when parsing ints.Damien George2014-05-28
| | | | Also unifies use of SMALL_INT_FITS macro across parser and runtime.
* py: Implement long int parsing in int(...).Damien George2014-05-28
| | | | Addresses issue #627.
* py: Rename MP_OBJ_NOT_SUPPORTED to MP_OBJ_NULL.Damien George2014-05-21
| | | | See issue #608 for justification.
* py: Remove emit_glue init and deinit. Needed only for debugging.Damien George2014-05-12
| | | | | Debugging output for emit_glue now simplified so that the init and deinit functions are no longer needed.
* py: Add support for __debug__ constant.Damien George2014-05-12
| | | | | | | | | __debug__ now resolves to True or False. Its value needs to be set by mp_set_debug(). TODO: call mp_set_debug in unix/ port. TODO: optimise away "if False:" statements in compiler.
* py: Don't expect that type->getiter() always returns iterator, check for NULL.Paul Sokolovsky2014-05-11
| | | | This is better than forcing each getiter() implementation to raise exception.
* py: Don't try to "bind" types store as attributes of objects.Paul Sokolovsky2014-05-11
| | | | | | | | This was hit when trying to make urlparse.py from stdlib run. Took quite some time to debug. TODO: Reconsile bound method creation process better, maybe callable is to generic type to bind at all?
