* py, emitters: Fix dummy_data size for bytecode and thumb.Damien George2014-05-10
| | | | | | | Thumb uses a bit less RAM, bytecode uses a tiny bit more, to avoid overflow of the dummy buffer in certain cases. Addresses issue #599.

* py: Improve handling of memory error in parser.Damien George2014-05-10
| | | | | | | | | | | Parser shouldn't raise exceptions, so needs to check when memory allocation fails. This patch does that for the initial set up of the parser state. Also, we now put the parser object on the stack. It's small enough to go there instead of on the heap. This partially addresses issue #558.

* objtype: Don't treat inheritance from "object" as from native type.Paul Sokolovsky2014-05-10
| | | | | | | | | | | "object" type in MicroPython currently doesn't implement any methods, and hopefully, we'll try to stay like that for as long as possible. Even if we have to add something eventually, look up from there might be handled in adhoc manner, as last resort (that's not compliant with Python3 MRO, but we're already non-compliant). Hence: 1) no need to spend type trying to lookup anything in object; 2) no need to allocate subobject when explicitly inheriting from object; 3) and having multiple bases inheriting from object is not a case of incompatible multiple inheritance.

* py: Combine native emitters to 1 glue function; distinguish viper.Damien George2014-05-10
| | | | | | | | This patch simplifies the glue between native emitter and runtime, and handles viper code like inline assember: return values are converted to Python objects. Fixes issue #531.

* stream: Add compliant handling of non-blocking readall().Paul Sokolovsky2014-05-07
|
* stream: Add compliant handling of non-blocking read()/write().Paul Sokolovsky2014-05-07
| | | | | | | | | | | In case of empty non-blocking read()/write(), both return None. read() cannot return 0, as that means EOF, so returns another value, and then write() just follows. This is still pretty unexpected, and typical "if not len:" check would treat this as EOF. Well, non-blocking files require special handling! This also kind of makes it depending on POSIX, but well, anything else should emulate POSIX anyway ;-).
* py, parser: Add commented-out code to discard doc strings.Damien George2014-05-06
| | | | | | Doesn't help with RAM reduction because doc strings are interned as soon as they are encountered, which is too soon to do any optimisations on them.

* py: Turn down amount of RAM parser and compiler use.Damien George2014-05-05
| | | | | | | | | | | | | | | | | | | | | | | | There are 2 locations in parser, and 1 in compiler, where memory allocation is not precise. In the parser it's the rule stack and result stack, in the compiler it's the array for the identifiers in the current scope. All other mallocs are exact (ie they don't allocate more than is needed). This patch adds tuning options (MP_ALLOC_*) to mpconfig.h for these 3 inexact allocations. The inexact allocations in the parser should actually be close to logarithmic: you need an exponentially larger script (absent pathological cases) to use up more room on the rule and result stacks. As such, the default allocation policy for these is now to start with a modest sized stack, but grow only in small increments. For the identifier arrays in the compiler, these now start out quite small (4 entries, since most functions don't have that many ids), and grow incrementally by 6 (since if you have more ids than 4, you probably have quite a few more, but it wouldn't be exponentially more). Partially addresses issue #560.

* py, unix: Add -v option, print bytecode dump if used.Paul Sokolovsky2014-05-05
| | | | | | | | | | This will work if MICROPY_DEBUG_PRINTERS is defined, which is only for unix/windows ports. This makes it convenient to user uPy normally, but easily get bytecode dump on the spot if needed, without constant recompiles back and forth. TODO: Add more useful debug output, adjust verbosity level on which specifically bytecode dump happens.

| * | mingw: Fix number of exponent digits in floating point formattingstijn2014-05-03
| | | | | | | | | | | | | | | | | | | | | By default mingw outputs 3 digits instead of the standard 2 so all float tests using printf fail. Using setenv at the start of the program fixes this. To accomodate calling platform specific initialization a MICROPY_MAIN_INIT_FUNC macro is used which is called in mp_init()
