With so many config options it's good to (at least try to) keep them
grouped into logical sections.
|

This patch fixes two main things:
- dicts can be printed directly using '%s' % dict
- %-formatting should not crash when passed a non-dict to, eg, '%(foo)s'

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.

0j to the power of negative now raises ZeroDivisionError, and 0j to the
power of positive returns 0.

E.g. uio.BytesIO(100) will allocate buffer with 100 bytes of space.

This PR is to address issue #2812.

Replaced by MICROPY_VFS and the VFS sub-system.

A signal is like a pin, but ca also be inverted (active low). As such, it
abstracts properties of various physical devices, like LEDs, buttons,
relays, buzzers, etc. To instantiate a Signal:
pin = machine.Pin(...)
signal = machine.Signal(pin, inverted=True)
signal has the same .value() and __call__() methods as a pin.

It should only be used for low-level things and with caution, for example
putting mounted VFS data in ROM or the static data section.
|

This provides mp_vfs_XXX functions (eg mount, open, listdir) which are
agnostic to the underlying filesystem type, and just require an object with
the relevant filesystem-like methods (eg .mount, .open, .listidr) which can
then be mounted.
These mp_vfs_XXX functions would typically be used by a port to implement
the "uos" module, and mp_vfs_open would be the builtin open function.
This feature is controlled by MICROPY_VFS, disabled by default.

In this, don't allocate copy, just return non-empty string. This helps
with a standard pattern of buffering data in case of short reads:
buf = b""
while ...:
s = f.read(...)
buf += s
...
For a typical case when single read returns all data needed, there won't
be extra allocation. This optimization helps uasyncio.

They are one-line functions and having them inline in mp_init/mp_deinit
eliminates the overhead of a function call, and matches how other state
is initialised in mp_init.

This is how CPython does it, and it's very useful to help users discover
the available modules for a given port, especially built-in and frozen
modules. The function does not list modules that are in the filesystem
because this would require a fair bit of work to do correctly, and is very
port specific (depending on the filesystem).

This builtin is configured using MICROPY_PY_BUILTINS_HELP, and is disabled
by default.

To be implemented later.

If result guaranteedly fits in a small int, it is handled in objint.c.
Otherwise, it is delegated to mp_obj_int_from_bytes_impl(), which should
be implemented by individual objint_*.c, similar to
mp_obj_int_to_bytes_impl().

The if-block that this unreachable code is in has a condition "f>=5" so
"fp_isless1(f)" will always fail.
|
|
Previouly, we had errors checked in callers, which led to duplicate code
or missing checks in some places.

This helps to improve code coverage. Note that most of the changes in
this patch are just de-denting the cases of the switch statements.

In this case it's allowed to be ignored.

Arguments to throw() for generators don't need to be exceptions.
|
|
If GeneratorExit is injected as a throw-value then that should lead to
the close() method being called, if it exists. If close() does not exist
then throw() should not be called, and this patch fixes this.

The commit d9047d3c8a99603884db25076c37778f50633ca6 introduced a bug
whereby "from a.b import c" stopped working for frozen packages. This is
because the path was not properly truncated and became "a//b". Such a
path resolves correctly for a "real" filesystem, but not for a search in
the list of frozen modules.

So that ports can pass their own custom options to mpy-cross.

One never needs to format integers with a base larger than 16 (but code
can be easily extended beyond this value if needed in the future).
|
|
|
|
|
|
|
|
This function should be able to parse integers with any value for the
base, because it is called by int('xxx', base).

UART REPL support was lost in os.dupterm() refactorings, etc. As
os.dupterm() is there, implement UART REPL support at the high level -
if MICROPY_STDIO_UART is set, make default boot.py contain os.dupterm()
call for a UART. This means that changing MICROPY_STDIO_UART value will
also require erasing flash on a module to force boot.py re-creation.

The lexer is very mature and this debug function is no longer used. If
it's really needed one can uncomment it and recompile.
