suspect-devices/circuitpython/py/obj.c, branch v1.7CircuitPython - a Python implementation for teaching coding with microcontrollershttps://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=v1.72016-03-14T22:40:39+00:00py: Fix passing of some wide int types to printf varg format list.2016-03-14T22:40:39+00:00Damien Georgedamien.p.george@gmail.com2016-03-14T22:40:39+00:00urn:sha1:2a1cca20b1e1a93c86c8c3a3254ab7150c85ac08
Passing an mp_uint_t to a %d printf format is incorrect for builds where
mp_uint_t is larger than word size (eg a nanboxing build). This patch
adds some simple casting to int in these cases.
py: Change exception traceback data to use size_t instead of mp_uint_t.2016-01-02T22:04:12+00:00Damien Georgedamien.p.george@gmail.com2016-01-02T22:04:12+00:00urn:sha1:3d2daa2d03e300ac64005b8659c31f04a0f7fd53
The traceback array stores qstrs and line numbers. qstrs are typed as
size_t, and line numbers should safely fit in size_t as well.
py: Wrap all obj-ptr conversions in MP_OBJ_TO_PTR/MP_OBJ_FROM_PTR.2015-11-29T14:25:35+00:00Damien Georgedamien.p.george@gmail.com2015-11-27T17:01:44+00:00urn:sha1:999cedb90ff0827cdb9dfe0e4faa6ebc1739d271
This allows the mp_obj_t type to be configured to something other than a
pointer-sized primitive type.
This patch also includes additional changes to allow the code to compile
when sizeof(mp_uint_t) != sizeof(void*), such as using size_t instead of
mp_uint_t, and various casts.

Gets rid of redundant double check for string type.
Also remove obsolete declaration of mp_obj_str_get_hash.
py: Add mp_obj_get_int_truncated and use it where appropriate.2015-05-12T22:05:53+00:00Damien Georgedamien.p.george@gmail.com2015-05-12T22:05:53+00:00urn:sha1:c50772d19fe2804a6d0258f89dd9967d3b516fd3
mp_obj_get_int_truncated will raise a TypeError if the argument is not
an integral type. Use mp_obj_int_get_truncated only when you know the
argument is a small or big int.
py: Convert hash API to use MP_UNARY_OP_HASH instead of ad-hoc function.2015-05-12T21:46:02+00:00Damien Georgedamien.p.george@gmail.com2015-05-11T12:25:19+00:00urn:sha1:c2a4e4effc81d8ab21bb014e34355643e5ca0da2
Hashing is now done using mp_unary_op function with MP_UNARY_OP_HASH as
the operator argument. Hashing for int, str and bytes still go via
fast-path in mp_unary_op since they are the most common objects which
need to be hashed.
This lead to quite a bit of code cleanup, and should be more efficient
if anything. It saves 176 bytes code space on Thumb2, and 360 bytes on
x86.
The only loss is that the error message "unhashable type" is now the
more generic "unsupported type for __hash__".
obj: Handle user instance hash based on Python adhoc rules.2015-05-05T19:48:19+00:00Paul Sokolovskypfalcon@users.sourceforge.net2015-05-04T19:41:32+00:00urn:sha1:37c6555b4419eb6027a345ee0c3e759d50da771f
User instances are hashable by default (using __hash__ inherited from
"object"). But if __eq__ is defined and __hash__ not defined in particular
class, instance is not hashable.
objsingleton: New home for Ellipsis and NotImplemented.2015-05-05T19:18:07+00:00Paul Sokolovskypfalcon@users.sourceforge.net2015-05-05T19:18:07+00:00urn:sha1:76677270218fb5732296e4fe1a0acbe05c8f818c
Having NotImplemented as MP_OBJ_SENTINEL turned out to be problematic
(it needs to be checked for in a lot of places, otherwise it'll crash
as would pass MP_OBJ_IS_OBJ()), so made a proper singleton value like
Ellipsis, both of them sharing the same type.
