* 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: Store bytecode arg names in bytecode (were in own array).Damien George2014-10-25
| | | | | | | | | | | | | | | | | | | | This saves a lot of RAM for 2 reasons: 1. For functions that don't have default values, var args or var kw args (which is a large number of functions in the general case), the mp_obj_fun_bc_t type now fits in 1 GC block (previously needed 2 because of the extra pointer to point to the arg_names array). So this saves 16 bytes per function (32 bytes on 64-bit machines). 2. Combining separate memory regions generally saves RAM because the unused bytes at the end of the GC block are saved for 1 of the blocks (since that block doesn't exist on its own anymore). So generally this saves 8 bytes per function. Tested by importing lots of modules: - 64-bit Linux gave about an 8% RAM saving for 86k of used RAM. - pyboard gave about a 6% RAM saving for 31k of used RAM.
* py: Add builtin memoryview object (mostly using array code).Damien George2014-10-23

* 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: Make mp_const_empty_bytes globally available.Damien George2014-10-21
|
* py: Convert [u]int to mp_[u]int_t where appropriate.Damien George2014-10-03
| | | | Addressing issue #50.
* 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: Add native json printing using existing print framework.Damien George2014-09-17
| | | | | Also add start of ujson module with dumps implemented. Enabled in unix and stmhal ports. Test passes on both.
* py: Implement divmod, % and proper // for floating point.Damien George2014-09-13
| | | | Tested and working on unix and pyboard.
* py: Enable struct/binary-helper to parse q and Q sized ints.Damien George2014-09-10
| | | | Addresses issue #848.
* py: Rename mp_builtin_id to mp_obj_id and make it public.Damien George2014-09-07
|
* stmhal: Implement generic select.select and select.poll.Damien George2014-09-07
|
* py: Add ioctl method to stream protocol; add initial modselect.Damien George2014-09-07
|
* py: Remove use of int type in obj.h.Damien George2014-08-30
| | | | Part of code cleanup, working towards resolving issue #50.
* 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.
* py: Make map, dict, set use mp_int_t/mp_uint_t exclusively.Damien George2014-08-30
| | | | Part of code cleanup, towards resolving 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.
* py: Use memmove instead of memcpy when appropriate.Damien George2014-08-29
| | | | | Found this bug by running unix/ tests with DEBUG=1 enabled when compiling.
* py: Improve efficiency of MP_OBJ_IS_STR_OR_BYTES.Damien George2014-08-27
| | | | | Saves ROM (16 on stmhal, 240 on 64-bit unix) and should be quicker since there is 1 less branch.
* Make int(b'123') work properly.Dave Hylands2014-08-26
|
* py: Fix bug where GC collected native/viper/asm function data.Damien George2014-08-24
| | | | | | | | 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.
* py: Allow viper to have type annotations.Damien George2014-08-15
| | | | | | | | | 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
* py: Implement builtin reversed() function.Damien George2014-08-12
| | | | | | | | reversed function now implemented, and works for tuple, list, str, bytes and user objects with __len__ and __getitem__. Renamed mp_builtin_len to mp_obj_len to make it publically available (eg for reversed).
* py: mp_buffer_info_t::buf may be valid, but NULL for empty objects.Paul Sokolovsky2014-08-10
| | | | | | This happens for example for zero-size arrays. As .get_buffer() method now has explicit return value, it's enough to distinguish success vs failure of getting buffer.
* py: Make MP_OBJ_NEW_SMALL_INT cast arg to mp_int_t itself.Damien George2014-07-31
| | | | Addresses issue #724.
* py: Add mp_obj_str_builder_end_with_len.Damien George2014-07-31
| | | | | This allows to create str's with a smaller length than initially asked for.
* Merge pull request #738 from dhylands/except-argsDamien George2014-07-29
|\ | | | | Add support for storing args during an exception raised by an irq.
| * 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 ```

* Rename machine_(u)int_t to mp_(u)int_t.Damien George2014-07-03
| | | | See discussion in issue #50.
* objstr: Be 8-bit clean even for repr().Paul Sokolovsky2014-06-14
| | | | | | | | | This will allow roughly the same behavior as Python3 for non-ASCII strings, for example, print("<phrase in non-Latin script>".split()) will print list of words, not weird hex dump (like Python2 behaves). (Of course, that it will print list of words, if there're "words" in that phrase at all, separated by ASCII-compatible whitespace; that surely won't apply to every human language in existence).
* objfun: Remove no longer used mp_obj_fun_prepare_simple_args().Paul Sokolovsky2014-06-11

| | | | Should finish addressing issue #524.
* objstr: Implement "%(key)s" % {} formatting for strings and dicts.Paul Sokolovsky2014-06-05
| | | | | Also, make sure that args to "*" format specifiers are bounds-checked properly and don't lead for segfaults in case of mismatch.
* py: Fix configurability of builtin slice.Damien George2014-06-01

| | | | Addresses issue #627.
* Change const byte* to const char* where sensible.Damien George2014-05-25

* py: Refactor slice helpers, preparing to support arbitrary slicing.Paul Sokolovsky2014-05-25
|
* objlist: Implement growing slice assignment.Paul Sokolovsky2014-05-25
| | | | | This means that complete slice operations are supported for lists (but not for bytearray's and array.array's).
* objslice: Support arbitrary objects start, stop, and step.Paul Sokolovsky2014-05-25
| | | | | Older int-only encoding is not expressive enough to support arbitrary slice assignment operations.
