suspect-devices/circuitpython/py/objexcept.c, branch v1.8.7CircuitPython - a Python implementation for teaching coding with microcontrollershttps://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=v1.8.72016-11-13T23:29:09+00:00py/objexcept: Allow clearing traceback with 'exc.__traceback__ = None'.2016-11-13T23:29:09+00:00Paul Sokolovskypfalcon@users.sourceforge.net2016-11-13T23:23:30+00:00urn:sha1:c3d96d387c461c25ca3298dfa73d2a4efb45f1e7
We allow 'exc.__traceback__ = None' assignment as a low-level optimization
of pre-allocating exception instance and raising it repeatedly - this
avoids memory allocation during raise. However, uPy will keep adding
traceback entries to such exception instance, so before throwing it,
traceback should be cleared like above.
'exc.__traceback__ = None' syntax is CPython compatible. However, unlike
it, reading that attribute or setting it to any other value is not
supported (and not intended to be supported, again, the only reason for
adding this feature is to allow zero-memalloc exception raising).
py/objexcept: Don't convert errno to str in constructor, do it in print.2016-05-12T13:27:52+00:00Damien Georgedamien.p.george@gmail.com2016-05-12T13:27:52+00:00urn:sha1:9a9249964155f333131bbd728ffc755e80dc68a2
OSError's are now printed like:
OSError: [Errno 1] EPERM
but only if the string corresponding to the errno is found.
py: Add mp_errno_to_str() and use it to provide nicer OSError msgs.2016-05-12T12:20:40+00:00Damien Georgedamien.p.george@gmail.com2016-05-12T12:20:40+00:00urn:sha1:d45e5f8c357d13e66aeac644e2b5ead8c734025f
If an OSError is raised with an integer argument, and that integer
corresponds to an errno, then the string for the errno is used as the
argument to the exception, instead of the integer. Only works if
the uerrno module is enabled.
py: add async/await/async for/async with syntax2016-04-13T14:26:38+00:00pohmeliemultisosnooley@gmail.com2016-01-27T20:23:11+00:00urn:sha1:81ebba7e0236163b7594938201bf3a6b802ebfaa
They are sugar for marking function as generator, "yield from"
and pep492 python "semantically equivalents" respectively.
@dpgeorge was the original author of this patch, but @pohmelie made
changes to implement `async for` and `async with`.
py: Change first arg of type.make_new from mp_obj_t to mp_obj_type_t*.2016-01-11T00:49:27+00:00Damien Georgedamien.p.george@gmail.com2016-01-03T15:55:55+00:00urn:sha1:5b3f0b7f39bd67cc9182993c288f09f67a0890df
The first argument to the type.make_new method is naturally a uPy type,
and all uses of this argument cast it directly to a pointer to a type
structure. So it makes sense to just have it a pointer to a type from
the very beginning (and a const pointer at that). This patch makes
such a change, and removes all unnecessary casting to/from mp_obj_t.
py: Change type signature of builtin funs that take variable or kw args.2016-01-11T00:49:27+00:00Damien Georgedamien.p.george@gmail.com2016-01-03T14:21:40+00:00urn:sha1:4b72b3a133ea87a1ef8b964508dc25c551ccf093
With this patch the n_args parameter is changed type from mp_uint_t to
size_t.
py: Change type of .make_new and .call args: mp_uint_t becomes size_t.2016-01-11T00:48:41+00:00Damien Georgedamien.p.george@gmail.com2016-01-03T09:59:18+00:00urn:sha1:a0c97814dfcb0debbde8be99539e3d5ca2334e54
This patch changes the type signature of .make_new and .call object method
slots to use size_t for n_args and n_kw (was mp_uint_t. Makes code more
efficient when mp_uint_t is larger than a machine word. Doesn't affect
ports when size_t and mp_uint_t have the same size.
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.
py: Add MP_ROM_* macros and mp_rom_* types and use them.2015-11-29T14:25:04+00:00Damien Georgedamien.p.george@gmail.com2015-11-27T13:38:15+00:00urn:sha1:cbf7674025814797f5c537d6d1c195efe58ccaaf
