This is to keep the top-level directory clean, to make it clear what is
core and what is a port, and to allow the repository to grow with new ports
in a sustainable way.

There were several different spellings of MicroPython present in comments,
when there should be only one.

The with semantics of this function is close to
pkg_resources.resource_stream() function from setuptools, which
is the canonical way to access non-source files belonging to a package
(resources), regardless of what medium the package uses (e.g. individual
source files vs zip archive). In the case of MicroPython, this function
allows to access resources which are frozen into the executable, besides
accessing resources in the file system.
This is initial stage of the implementation, which actually doesn't
implement "package" part of the semantics, just accesses frozen resources
from "root", or filesystem resource - from current dir.

Prior to making this a config option it was previously available on these
(and all other) ports, and it makes sense to keep it enabled for mpy-cross
as well as ports that have a decent amount of space for the code.
|
|
|
|
It can still be overwritten by a port in mpconfigport.h but for almost
all cases one can use the provided default.
|
|
|
|
Updated modbuiltin.c to add conditional support for 3-arg calls to
pow() using MICROPY_PY_BUILTINS_POW3 config parameter. Added support in
objint_mpz.c for for optimised implementation.
|
|
Everyone should now be using the new ooFatFs library. The old one is no
longer supported and will be removed.
|
|
|
|
Replaced by MICROPY_VFS and the VFS sub-system.
|
|
This patch includes a new module "uos_vfs" which can be used for testing
the VFS syb-system.

To not conflict with recently made available globally baremetal
moduselect.

Implementations of persistent-code reader are provided for POSIX systems
and systems using FatFS. Macros to use these are MICROPY_READER_POSIX and
MICROPY_READER_FATFS respectively. If an alternative implementation is
needed then a port can define the function mp_reader_new_file.

Disable by default, enable in unix port.

|
This type was used only for the typedef of mp_obj_t, which is now defined
by the object representation. So we can now remove this unused typedef,
to simplify the mpconfigport.h file.
|
|
Fixes build errors such as
"../lib/utils/printf.c:43:5: error: expected parameter declarator"
|
|
Default is disabled, enabled for unix port. Saves 600 bytes on x86.
|
|
|
|
To filter out even prototypes of mp_stream_posix_*() functions, which
require POSIX types like ssize_t & off_t, which may be not available in
some ports.
|
|
This allows to use printf() in a any source file with unix port, for quick
debugging.
|
|
Also, fix a warning text (remove "duplicate" BytesWarning).
|
|
Make variable MICROPY_SSL_AXTLS=1 should be defined to activate modussl_axtls
and link with -laxtls.
|
|
|
|
It's enabled mostly for unit testing, and we do that in full with coverage
build.

When built for Linux, libffi includes very bloated and workaround exec-alloc
implementation required to work around SELinux and other "sekuritee" features
which real people don't use. MicroPython has own alloc-exec implementation,
used to alloc memory for @micropython.native code. With this option enabled,
uPy's implementation will override libffi's. This saves 11K on x86_64 (and
that accounts for more than half of the libffi code size).
TODO: Possibly, we want to refactor this option to allow either use uPy's
implementation even for libffi, or allow to use libffi's implementation even
for uPy.

Disabled by default, enabled in unix port. Need for this method easily
pops up when working with text UI/reporting, and coding workalike
manually again and again counter-productive.
|
|
To use frozen bytecode make a subdirectory under the unix/ directory
(eg frozen/), put .py files there, then run:
make FROZEN_MPY_DIR=frozen
Be sure to build from scratch. The .py files will then be available for
importing.
|

|
|
These are *defined* per-port, but why redeclare them again and again.
|
|
The config variable MICROPY_MODULE_FROZEN is now made of two separate
parts: MICROPY_MODULE_FROZEN_STR and MICROPY_MODULE_FROZEN_MPY. This
allows to have none, either or both of frozen strings and frozen mpy
files (aka frozen bytecode).
|
|
By default it uses mp_plat_print, but a port may override it to another
value with MICROPY_DEBUG_PRINTER_DEST.

Calling it from mp_init() is too late for some ports (like Unix), and leads
to incomplete stack frame being captured, with following GC issues. So, now
each port should call mp_stack_ctrl_init() on its own, ASAP after startup,
and taking special precautions so it really was called before stack variables
get allocated (because if such variable with a pointer is missed, it may lead
to over-collecting (typical symptom is segfaulting)).

Seedable and reproducible pseudo-random number generator. Implemented
functions are getrandbits(n) (n <= 32) and seed().

POSIX doesn't guarantee something like that to work, but it works on any
system with careful signal implementation. Roughly, the requirement is
that signal handler is executed in the context of the process, its main
thread, etc. This is true for Linux. Also tested to work without issues
on MacOSX.
