This is because mp_setup_code_state() assumes that keys in kwargs are qstrs (for efficiency). Thanks to @jepler for finding the bug. 2018-03-13T03:03:15+00:00 Damien George damien.p.george@gmail.com 2018-03-13T03:03:15+00:00 urn:sha1:e0bc438e4badb8f2d356479a3bee2b9c45fd69ca If this function is used then objlist.h is already included to get the definition of mp_obj_list_t. 2018-03-13T03:01:55+00:00 Damien George damien.p.george@gmail.com 2018-03-13T03:01:55+00:00 urn:sha1:9f811e9096819230905a5eb47812934531005403 2018-02-21T11:39:25+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2018-02-05T22:06:42+00:00 urn:sha1:970eedce8f37af46cb2b67fa0e91d76c82057541 So far, implements just append() and popleft() methods, required for a normal queue. Constructor doesn't accept an arbitarry sequence to initialize from (am empty deque is always created), so an empty tuple must be passed as such. Only fixed-size deques are supported, so 2nd argument (size) is required. There's also an extension to CPython - if True is passed as 3rd argument, append(), instead of silently overwriting the oldest item on queue overflow, will throw IndexError. This behavior is desired in many cases, where queues should store information reliably, instead of silently losing some items. 2018-02-15T05:50:02+00:00 Damien George damien.p.george@gmail.com 2018-02-15T05:50:02+00:00 urn:sha1:73d1d20b46dda54340ad2819b865f47ca25f4850 This constant exception instance was once used by m_malloc_fail() to raise a MemoryError without allocating memory, but it was made obsolete long ago by 3556e45711c3b7ec712748d013e678d035185bdd. The functionality is now replaced by the use of mp_emergency_exception_obj which lives in the global uPy state, and which can handle any exception type, not just MemoryError. 2017-12-11T11:39:12+00:00 Damien George damien.p.george@gmail.com 2017-12-11T11:39:12+00:00 urn:sha1:2759bec8587b0c0b7da1fa3a013e4f1b1530ad27 The nan-boxing representation has an extra 16-bits of space to store small-int values, and making use of it allows to create and manipulate full 32-bit positive integers (ie up to 0xffffffff) without using the heap. 2017-11-16T02:17:51+00:00 Damien George damien.p.george@gmail.com 2017-11-16T02:17:51+00:00 urn:sha1:4601759bf59e16b860a3f082e9aa4ea78356bf92 This patch simplifies the str creation API to favour the common case of creating a str object that is not forced to be interned. To force interning of a new str the new mp_obj_new_str_via_qstr function is added, and should only be used if warranted. Apart from simplifying the mp_obj_new_str function (and making it have the same signature as mp_obj_new_bytes), this patch also reduces code size by a bit (-16 bytes for bare-arm and roughly -40 bytes on the bare-metal archs). 2017-09-04T13:35:46+00:00 Damien George damien.p.george@gmail.com 2017-09-04T13:35:46+00:00 urn:sha1:77a48e8cd493c0b0e0ca2d2ad58a110a23c6a232 2017-09-02T20:05:24+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2017-09-02T18:19:01+00:00 urn:sha1:9950865c39044e9fef295d0676af7c5fd55289ea These are now returned as "operation not supported" instead of raising TypeError. In particular, this fixes equality for float vs incompatible types, which now properly results in False instead of exception. This also paves the road to support reverse operation (e.g. __radd__) with float objects. This is achieved by introducing mp_obj_get_float_maybe(), similar to existing mp_obj_get_int_maybe().
