Damien George 1e9a92f84f py: Use shorter, static error msgs when ERROR_REPORTING_TERSE enabled. 
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.

Paul Sokolovsky b1422de12f py: Allow to override port config file and thus have >1 configs per port.

Damien George c9fc620723 py: Implement compile builtin, enabled only on unix port. 
This should be pretty compliant with CPython, except perhaps for some
corner cases to do with globals/locals context.

Addresses issue #879.

Damien George c14a81662c py: Add module weak link support. 
With this patch a port can enable module weak link support and provide
a dict of qstr->module mapping.  This mapping is looked up only if an
import fails to find the requested module in the filesystem.

This allows to have the builtin module named, eg, usocket, and provide
a weak link of "socket" to the same module, but this weak link can be
overridden if a file by the name "socket.py" is found in the import
path.

Paul Sokolovsky 722e562736 py: Correctly set sys.maxsize value for 64-bit. 
Type representing signed size doesn't have to be int, so use special value
which defaults to SSIZE_MAX, but as it's not defined by C standard (but rather
by POSIX), allow ports to set it.

Damien George 3c658a4e75 py: Fix bug where GC collected native/viper/asm function data. 
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.

Damien George 2ac4af6946 py: Allow viper to have type annotations. 
Viper functions can now be annotated with the type of their arguments
and return value.  Eg:

@micropython.viper
def f(x:int) -> int:
    return x + 1

Damien George 07133415d2 Merge pull request #738 from dhylands/except-args

Paul Sokolovsky d0f5e61ab5 py: Implement __file__ attribute for modules. 2014-07-28 21:21:59 +03:00
Dave Hylands 5b7fd20fea Add support for storing args during an exception raised by an irq. 
The user code should call micropython.alloc_emergency_exception_buf(size)
where size is the size of the buffer used to print the argument
passed to the exception.

With the test code from #732, and a call to
micropython.alloc_emergenncy_exception_buf(100) the following error is
now printed:
```python
>>> import heartbeat_irq
Uncaught exception in Timer(4) interrupt handler
Traceback (most recent call last):
  File "0://heartbeat_irq.py", line 14, in heartbeat_cb
NameError: name 'led' is not defined
```

Paul Sokolovsky 8215847b4d moductypes: Foreign data interface module, roughly based on ctype ideas. 
But much smaller and memory-efficient. Uses Python builtin data structures
(dict, tuple, int) to describe structure layout.

Paul Sokolovsky 4e0eeebdc2 py: Implement sys.maxsize, standard way to check platform "bitness". 
Implementing it as a static constant is a bit peculiar and require cooperation
from long int implementation.

Paul Sokolovsky cb78f862cb py: Allow to disable array module and bytearray type. 
array.array and bytearray share big deal of code, so to get real savings,
both need to be disabled.

Paul Sokolovsky 23668698cb py: Add portable framework to query/check C stack usage. 
Such mechanism is important to get stable Python functioning, because Python
function calling is handled with C stack. The idea is to sprinkle
STACK_CHECK() calls in places where there can be C recursion.

TODO: Add more STACK_CHECK()'s.

Damien George 5042bce8fb py: Don't automatically intern strings in parser. 
This completes non-automatic interning of strings in the parser, so that
doc strings don't take up RAM.  It complicates the parser and compiler,
and bloats stmhal by about 300 bytes.  It's complicated because now
there are 2 kinds of parse-nodes that can be strings: interned leaves
and non-interned structs.

Paul Sokolovsky 9e29666bf9 py: Implement proper separation between io.FileIO and io.TextIOWrapper. 
io.FileIO is binary I/O, ans actually optional. Default file type is
io.TextIOWrapper, which provides str results. CPython3 explicitly describes
io.TextIOWrapper as buffered I/O, but we don't have buffering support yet
anyway.
