Damien George 17ae2395c2 py: Use memmove instead of memcpy when appropriate.
Found this bug by running unix/ tests with DEBUG=1 enabled when
compiling.

Damien George a75b02ea9b py: Improve efficiency of MP_OBJ_IS_STR_OR_BYTES.
Saves ROM (16 on stmhal, 240 on 64-bit unix) and should be quicker since
there is 1 less branch.

Dave Hylands b7f7c655ed Make int(b'123') work properly. 2014-08-26 19:15:04 -07:00
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 4c03b3a899 py: Implement builtin reversed() function.
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).

Paul Sokolovsky 7133d91773 py: mp_buffer_info_t::buf may be valid, but NULL for empty objects.
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.

Damien George bb4c6f35c6 py: Make MP_OBJ_NEW_SMALL_INT cast arg to mp_int_t itself.
Addresses issue #724.
2014-07-31 10:49:14 +01:00
Damien George 5f27a7e811 py: Add mp_obj_str_builder_end_with_len.
This allows to create str's with a smaller length than initially asked
for.

Damien George 07133415d2 Merge pull request #738 from dhylands/except-args
Add support for storing args during an exception raised by an irq.

Damien George adf0f2ae1a py: Change stream protocol API: fns return uint; is_text for text. 2014-07-27 22:38:58 +01:00
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
```

Damien George 40f3c02682 Rename machine_(u)int_t to mp_(u)int_t.
See discussion in issue #50.

Paul Sokolovsky 2ec38a17d4 objstr: Be 8-bit clean even for repr().
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).

Paul Sokolovsky 0c0f446840 objfun: Remove no longer used mp_obj_fun_prepare_simple_args(). 2014-06-11 20:43:47 +03:00
Paul Sokolovsky b4efac14cd py: Make sure getattr() works with non-interned strings (by interning them). 2014-06-08 01:15:06 +03:00
Damien George f0778a7ccb py: Implement default keyword only args.
Should finish addressing issue #524.
2014-06-07 22:01:00 +01:00
Paul Sokolovsky 75ce9256b2 objstr: Implement "%(key)s" % {} formatting for strings and dicts.
Also, make sure that args to "*" format specifiers are bounds-checked
properly and don't lead for segfaults in case of mismatch.

Damien George c49ddb9315 py: Fix configurability of builtin slice. 2014-06-01 13:49:35 +01:00
Damien George fb510b3bf9 Rename bultins config variables to MICROPY_PY_BUILTINS_*.
This renames:
MICROPY_PY_FROZENSET -> MICROPY_PY_BUILTINS_FROZENSET
MICROPY_PY_PROPERTY -> MICROPY_PY_BUILTINS_PROPERTY
MICROPY_PY_SLICE -> MICROPY_PY_BUILTINS_SLICE
MICROPY_ENABLE_FLOAT -> MICROPY_PY_BUILTINS_FLOAT

See issue #35 for discussion.

Damien George d1e355ea8e py: Fix check of small-int overflow when parsing ints.
Also unifies use of SMALL_INT_FITS macro across parser and runtime.
2014-05-28 14:51:12 +01:00
Damien George 503d611033 py: Implement long int parsing in int(...).
Addresses issue #627.
2014-05-28 14:07:21 +01:00
Damien George 2617eebf2f Change const byte* to const char* where sensible.
This removes need for some casts (at least, more than it adds need
for new casts!).

Paul Sokolovsky 5fd5af98d0 objlist: Implement support for arbitrary (3-arg) slices. 2014-05-25 22:12:56 +03:00
Paul Sokolovsky de4b9329f9 py: Refactor slice helpers, preparing to support arbitrary slicing. 2014-05-25 21:21:57 +03:00
Paul Sokolovsky 2705f4c782 objlist: Implement growing slice assignment.
This means that complete slice operations are supported for lists (but not
for bytearray's and array.array's).
2014-05-25 02:36:12 +03:00
Paul Sokolovsky afaaf535e6 objslice: Support arbitrary objects start, stop, and step.
Older int-only encoding is not expressive enough to support arbitrary slice
assignment operations.

Damien George 7a4ddd2428 Add SystemExit exception and use it in unix/ and stmhal/ ports.
Addresses issue #598.

Damien George 6ac5dced24 py: Rename MP_OBJ_NOT_SUPPORTED to MP_OBJ_NULL.
See issue #608 for justification.

Paul Sokolovsky a47b64ae2d objstringio: Implement io.BytesIO.
Done in generalized manner, allowing any stream class to be specified as
working with bytes.
2014-05-15 07:28:19 +03:00
Damien George 2323ef9182 py: Rename globally-accessible tuple functions, prefix with mp_obj_.
Likely there are other functions that should be renamed, but this is a
start.

Paul Sokolovsky ea9708092e objtuple: Go out of the way to support comparison of subclasses.
Two things are handled here: allow to compare native subtypes of tuple,
e.g. namedtuple (TODO: should compare type too, currently compared
duck-typedly by content). Secondly, allow user sunclasses of tuples
(and its subtypes) be compared either. "Magic" I did previously in
objtype.c covers only one argument (lhs is many), so we're in trouble
when lhs is native type - there's no other option besides handling
rhs in special manner. Fortunately, this patch outlines approach with
fast path for native types.

Paul Sokolovsky 94d8246272 objlist: Implement non-growing slice assignment.
Slice value to assign can be only a list so far too.

Paul Sokolovsky b181b581aa objset: Give up and implement frozenset.
Tired of patching CPython stdlib for it.

Damien George 04b9147e15 Add license header to (almost) all files.
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/.

Paul Sokolovsky 418aca976c objclosure, objcell: Print detailed representation if was requested.
Well, it is bound to "detailed error reporting", but that's closest what we
have now without creating new entities.

Paul Sokolovsky d8351ca8a0 objtype: .print() Exception instances in adhoc way.
This is ugly, just as expected.

Also, clear up freed slots in containers.

Damien George 2827d62e8b py: Implement keyword-only args.
Implements 'def f(*, a)' and 'def f(*a, b)', but not default
keyword-only args, eg 'def f(*, a=1)'.

Partially addresses issue #524.

Damien George 3558f62fb5 py: Making closures now passes pointer to stack, not a tuple for vars.
Closed over variables are now passed on the stack, instead of creating a
tuple and passing that.  This way memory for the closed over variables
can be allocated within the closure object itself.  See issue #510 for
background.
