* py: Make gc.enable/disable just control auto-GC; alloc is still allowed.Damien George2014-10-31
| | | | | | gc.enable/disable are now the same as CPython: they just control whether automatic garbage collection is enabled or not. If disabled, you can still allocate heap memory, and initiate a manual collection.
* py: Add mp_pending_exception global variable, for VM soft interrupt.Damien George2014-10-25
| | | | | | | | | | | This allows to implement KeyboardInterrupt on unix, and a much safer ctrl-C in stmhal port. First ctrl-C is a soft one, with hope that VM will notice it; second ctrl-C is a hard one that kills anything (for both unix and stmhal). One needs to check for a pending exception in the VM only for jump opcodes. Others can't produce an infinite loop (infinite recursion is caught by stack check).
* py: Remove unused and unneeded SystemError exception.Damien George2014-10-22
| | | | | It's purpose is for internal errors that are not catastrophic (ie not as bad as RuntimeError). Since we don't use it, we don't need it.
* py: Fix dummy definition of BEGIN/END_ATOMIC_SECTION.Damien George2014-10-15

* py: Remove IOError since it's deprecated; use OSError instead.Damien George2014-09-30
| | | | | | | | | | | In CPython IOError (and EnvironmentError) is deprecated and aliased to OSError. All modules that used to raise IOError now raise OSError (or a derived exception). In Micro Python we never used IOError (except 1 place, incorrectly) and so don't need to keep it. See http://legacy.python.org/dev/peps/pep-3151/ for background.
* py: Tidy up exception matching; allow matching of tuple of exceptions.Damien George2014-09-25
| | | | Addresses issue #864.
* py: Change all uint to mp_uint_t in obj.h.Damien George2014-08-30
| | | | Part of code cleanup, working towards resolving issue #50.
* py: Make tuple and list use mp_int_t/mp_uint_t.Damien George2014-08-30
| | | | Part of code cleanup, to resolve issue #50.
* Change some parts of the core API to use mp_uint_t instead of uint/int.Damien George2014-08-30
| | | | Addressing issue #50, still some way to go yet.
* stmhal: Make enable_irq and disable_irq inline functions.Damien George2014-08-25
| | | | | | | | | | | | These functions are generally 1 machine instruction, and are used in critical code, so makes sense to have them inline. Also leave these functions uninverted (ie 0 means enable, 1 means disable) and provide macro constants if you really need to distinguish the states. This makes for smaller code as well (combined with inlining). Applied to teensy port as well.
* Add save/restore_irqDave Hylands2014-08-25
| | | | Factored irq functions into a separate file.
* Add support for storing args during an exception raised by an irq.Dave Hylands2014-07-25
| | | | | | | | | | | | | | | | | 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 ```

* Change const byte* to const char* where sensible.Damien George2014-05-25

* py: Rename globally-accessible tuple functions, prefix with mp_obj_.Damien George2014-05-11
| | | | | Likely there are other functions that should be renamed, but this is a start.
* Add license header to (almost) all files.Damien George2014-05-03
| | | | | | | Blanket wide to all .c and .h files. Some files originating from ST are difficult to deal with (license wise) so it was left out of those. Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/.

* objtype: .print() Exception instances in adhoc way.Paul Sokolovsky2014-05-02

* 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.

| * 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.

| | | | | | | | | | | | | | | | | | 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.
