Damien George 58ba4c3b4c py: Check explicitly for memory allocation failure in parser.
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.

Damien George f0954e3fac py: Add emergency exception object for when heap allocation fails. 2014-04-10 14:38:25 +01:00
Damien George ea13f407a3 py: Change nlr_jump to nlr_raise, to aid in debugging.
This does not affect code size or performance when debugging turned off.

To address issue #420.

Damien George 6902eeda25 py: Add m_malloc_fail function to handle memory allocation error.
A malloc/realloc fail now throws MemoryError.

Paul Sokolovsky a96d3d0840 objexcept: No more magic messages in exceptions, only exception arguments.
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.

Damien George d17926db71 Rename rt_* to mp_*.
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.

Paul Sokolovsky c4d589e2bb objgenerator: close(): Throw instance of GeneratorExit (not type).
To comply with Python semantics and allow use of mp_obj_is_subclass_fast()
for exception matching.

Damien George c63f984647 py: Thin out predefined exceptions.
Only exceptions that are actually used are left prefedined.  Hierarchy
is still there, and removed exceptions are just commented out.

Paul Sokolovsky af1ae30399 objexcept: Add mp_obj_exception_get_value() convenience function.
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.

Paul Sokolovsky 962b1cd1b1 objgenerator: Implement return with value and .close() method.
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.

throwing exceptions, etc.

Damien George 22a0865d54 py: Improve exception bases, reduces ROM usage.

Damien George c5966128c7 Implement proper exception type hierarchy.
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.

Damien George a71c83a1d1 Change mp_obj_type_t.name from const char * to qstr.
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.

Paul Sokolovsky d5df6cd44a Replace global "static" -> "STATIC", to allow "analysis builds". Part 1.
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().

Damien George cbd2f7482c py: Add module/function/class name to exceptions.
Exceptions know source file, line and block name.

Also tidy up some debug printing functions and provide a global
flag to enable/disable them.

Damien George 08335004cf Add source file name and line number to error messages.
Byte code has a map from byte-code offset to source-code line number,
used to give better error messages.

Damien George 20006dbba9 Make VM stack grow upwards, and so no reversed args arrays.
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.

Paul Sokolovsky ddf2178d83 Refactor exception objects to have better impl of Python-side interface.
This implements internal args tuple of arguments, while still keeping
object useful for reporting C-side errors.

Further elaboration is needed.

Damien d99b05282d Change object representation from 1 big union to individual structs.
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).
