Paul Sokolovsky 96eec4f8a6 compile: Don't try to constant-fold division by zero.
The way it is, just crashes app. And optimizing to
"raise ZeroDivisionError" is probably too much.

Paul Sokolovsky 864038dab7 objfloat: Make sure that floats always have dot (for C "double" type case).
This matches CPython behavior and hopefully can be treated as general
Python semantics.

Paul Sokolovsky a8e60c1fde objfloat: Missing default: caused incorrect results for unimplemented ops. 2014-03-31 02:23:56 +03:00
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 df6567e634 Merge map.h into obj.h.
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.

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 9a54a22318 objgenerator.throw(): Throwing GeneratorExit is equivalent to .close().
According to PEP380 and caught by CPython test_pep380.py .

Damien George d7592a1c3f py: Fix reraise logic. 2014-03-30 00:54:48 +00:00
Paul Sokolovsky 0c904df8e6 vm: Save current active exception on opening new try block.
Required to reraise correct exceptions in except block, regardless if more
try blocks with active exceptions happen in the same except block.

P.S. This "automagic reraise" appears to be quite wasteful feature of Python
- we need to save pending exception just in case it *might* be reraised.
Instead, programmer could explcitly capture exception to a variable using
"except ... as var", and reraise that. So, consider disabling argless raise
support as an optimization.

Paul Sokolovsky 40d6d29af6 vm: Elaborate comments for WITH_CLEANUP, other cosmetic fixes. 2014-03-29 18:46:04 +02:00
Damien George c689c19471 py: Make MP_BC_SETUP_WITH use the bytecode stack for load_method.
The compiler allocates 7 entries on the stack for a with statement
(following CPython, but probably can be reduced).  This is enough for
the method load and call in SETUP_WITH.

Damien George d1e443d0bc py: Free unique_code slot for outer module.
Partly (very partly!) addresses issue #386.  Most importantly, at the
REPL command line, each invocation does not now lead to increased memory
usage (unless you define a function/lambda).

Paul Sokolovsky 682f9e639d vm: Make sure that exception triple is <type, instance, traceback>.
This reduntant triple is one of the ugliest parts of Python, which they
chickened out to fix in Python3. We really should consider passing just
as single exception instance (without breaking Python-level APIs of course),
but until we do, let's follow CPython layout.
