* objexcept: Add mp_obj_new_exception_arg1() convenience function.Paul Sokolovsky2014-04-22
|
* py: Check explicitly for memory allocation failure in parser.Damien George2014-04-10
| | | | | | Previously, a failed malloc/realloc would throw an exception, which was not caught. I think it's better to keep the parser free from NLR (exception throwing), hence this patch.
* py: Add emergency exception object for when heap allocation fails.Damien George2014-04-10

* 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: Add m_malloc_fail function to handle memory allocation error.Damien George2014-04-04
| | | | A malloc/realloc fail now throws MemoryError.
* objexcept: No more magic messages in exceptions, only exception arguments.Paul Sokolovsky2014-03-31
| | | | | | | One of the reason for separate "message" (besides still unfulfilled desire to optimize memory usage) was apparent special handling of exception with messages by CPython. Well, the message is still just an exception argument, it just printed specially. Implement that with PRINT_EXC printing format.
* 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.

* objgenerator: close(): Throw instance of GeneratorExit (not type).Paul Sokolovsky2014-03-28
| | | | | To comply with Python semantics and allow use of mp_obj_is_subclass_fast() for exception matching.
* py: Thin out predefined exceptions.Damien George2014-03-27
| | | | | Only exceptions that are actually used are left prefedined. Hierarchy is still there, and removed exceptions are just commented out.

| * objexcept: Add mp_obj_exception_get_value() convenience function.Paul Sokolovsky2014-03-26
| | | | | | | | | | | | | | This gets "value" of exceptions in the sense as it's defined for StopIteration.value (i.e. args[0] or None). TODO: This really should be inline function.

| * | objgenerator: Implement return with value and .close() method.Paul Sokolovsky2014-03-26
| | | | | | | | | | | | | | | | | | Return with value gets converted to StopIteration(value). Implementation keeps optimizing against creating of possibly unneeded exception objects, so there're considerable refactoring to implement these features.

* py: VM never throws an exception, instead returns a status and value.Damien George2014-02-15
| | | | | Addresses issue #290, and hopefully sets up things to allow generators throwing exceptions, etc.
* py: Improve exception bases, reduces ROM usage.Damien George2014-02-15
| | | | Thanks to @pfalcon for the tip!
* 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().

* py: Add full traceback to exception printing.Damien George2014-01-19
|
* py: Add module/function/class name to exceptions.Damien George2014-01-19
| | | | | | | Exceptions know source file, line and block name. Also tidy up some debug printing functions and provide a global flag to enable/disable them.
* Add source file name and line number to error messages.Damien George2014-01-18
| | | | | Byte code has a map from byte-code offset to source-code line number, used to give better error messages.
* Make VM stack grow upwards, and so no reversed args arrays.Damien George2014-01-18
| | | | | | | | | | | | | | | Change state layout in VM so the stack starts at state[0] and grows upwards. Locals are at the top end of the state and number downwards. This cleans up a lot of the interface connecting the VM to C: now all functions that take an array of Micro Python objects are in order (ie no longer in reverse). Also clean up C API with keyword arguments (call_n and call_n_kw replaced with single call method that takes keyword arguments). And now make_new takes keyword arguments. emitnative.c has not yet been changed to comply with the new order of stack layout.

* Refactor exception objects to have better impl of Python-side interface.Paul Sokolovsky2014-01-15
| | | | | | | This implements internal args tuple of arguments, while still keeping object useful for reporting C-side errors. Further elaboration is needed.

* 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).
