- Changed: ValueError, TypeError, NotImplementedError
- OSError invocations unchanged, because the corresponding utility
function takes ints, not strings like the long form invocation.
- OverflowError, IndexError and RuntimeError etc. not changed for now
until we decide whether to add new utility functions.
all: Use the name MicroPython consistently in comments2017-07-31T08:35:40+00:00Alexander Steffendevel.20.webmeister@spamgourmet.com2017-06-30T07:22:17+00:00urn:sha1:55f33240f3d7051d4213629e92437a36f1fac50e
There were several different spellings of MicroPython present in comments,
when there should be only one.
all: Unify header guard usage.2017-07-18T01:57:39+00:00Alexander Steffendevel.20.webmeister@spamgourmet.com2017-06-29T21:14:58+00:00urn:sha1:299bc625864b9e624ed599c94a5f95870516139a
The code conventions suggest using header guards, but do not define how
those should look like and instead point to existing files. However, not
all existing files follow the same scheme, sometimes omitting header guards
altogether, sometimes using non-standard names, making it easy to
accidentally pick a "wrong" example.
This commit ensures that all header files of the MicroPython project (that
were not simply copied from somewhere else) follow the same pattern, that
was already present in the majority of files, especially in the py folder.
The rules are as follows.
Naming convention:
* start with the words MICROPY_INCLUDED
* contain the full path to the file
* replace special characters with _
In addition, there are no empty lines before #ifndef, between #ifndef and
one empty line before #endif. #endif is followed by a comment containing
the name of the guard macro.
py/grammar.h cannot use header guards by design, since it has to be
included multiple times in a single C file. Several other files also do not
need header guards as they are only used internally and guaranteed to be
included only once:
* MICROPY_MPHALPORT_H
* mpconfigboard.h
* mpconfigport.h
* mpthreadport.h
* pin_defs_*.h
* qstrdefs*.h
py: Add LOAD_SUPER_METHOD bytecode to allow heap-free super meth calls.2017-04-22T13:39:20+00:00Damien Georgedamien.p.george@gmail.com2017-04-18T23:45:59+00:00urn:sha1:dd11af209d226b7d18d5148b239662e30ed60bad
This patch allows the following code to run without allocating on the heap:
super().foo(...)
Before this patch such a call would allocate a super object on the heap and
then load the foo method and call it right away. The super object is only
needed to perform the lookup of the method and not needed after that. This
patch makes an optimisation to allocate the super object on the C stack and
discard it right after use.
Changes in code size due to this patch are:
bare-arm: +128
minimal: +232
unix x64: +416
unix nanbox: +364
stmhal: +184
esp8266: +340
cc3200: +128
py: Remove MP_STATE_CTX, use MP_STATE_THREAD instead (it's an alias).2017-03-24T07:43:28+00:00Damien Georgedamien.p.george@gmail.com2017-03-24T07:43:28+00:00urn:sha1:64a4f11b2d6f880aa6fb1aaa10b2603d3faa1cd0
MP_STATE_CTX was recently aliased to MP_STATE_THREAD and can now be
removed.

Allows to iterate over the following without allocating on the heap:
- tuple
- list
- string, bytes
- bytearray, array
- dict (not dict.keys, dict.values, dict.items)
- set, frozenset
Allows to call the following without heap memory:
- all, any, min, max, sum
TODO: still need to allocate stack memory in bytecode for iter_buf.
py/runtime: Convert mp_uint_t to size_t where appropriate.2017-02-16T05:51:13+00:00Damien Georgedamien.p.george@gmail.com2017-02-16T04:32:34+00:00urn:sha1:4e3bac2e42788aa9312a6145aef18da083eac2dfpy/objtype: Implement __call__ handling for an instance w/o heap alloc.2016-11-21T22:33:55+00:00Paul Sokolovskypfalcon@users.sourceforge.net2016-11-21T22:33:55+00:00urn:sha1:037e6912c60f4f05a3866d525392f9c76914d0f1

py: Add mp_raise_OSError(errno) helper function.2016-10-07T02:31:59+00:00Damien Georgedamien.p.george@gmail.com2016-10-07T02:31:59+00:00urn:sha1:3a0a7717304cc34a4d6ef55f767666c918c185b5
This is an often used code pattern, and its use reduces code size of the
core by about 100 bytes.
