Jim Mussared 975a687447 py/mpconfig: Add MICROPY_PY_PLATFORM, enabled at extra features level.
Previously this was explicitly enabled on esp32/stm32/renesas/mimxrt/samd,
but didn't get a default feature level because it wasn't in py/mpconfig.h.

With this commit it's now enabled at the "extra features" level, which adds
rp2, unix-standard, windows, esp8266, webassembly, and some nrf boards.

Damien George 8ef5622b9b py/runtime: Always initialise sched_state in mp_init.
When MICROPY_SCHEDULER_STATIC_NODES is enabled, the logic is unchanged.

When MICROPY_SCHEDULER_STATIC_NODES is disable, sched_state is now always
initialised to MP_SCHED_IDLE when calling mp_init().  For example, the use
of mp_sched_vm_abort(), if it aborts a running scheduled function, can lead
to the scheduler starting off in a locked state when the runtime is
restarted, and then it stays locked.  This commit fixes that case by
resetting sched_state.

Jim Mussared 3533924c36 extmod/moddeflate: Add deflate module providing the DeflateIO class.
This provides similar functionality to the former zlib.DecompIO and
especially CPython's gzip.GzipFile for both compression and decompression.

This class can be used directly, and also can be used from Python to

gzip.GzipFile.

Speed LTO builds by using multiple threads
On my i5-1235U laptop this speeds LTO "partition=balanced" builds
substantially, because each "partition" can be run on a separate
CPU thread. I used "pygamer" as my test build with a parallelism of
`-j4`, and took the best elapsed time reported over 4 builds.

The improvement was from 34.6s to 24.0s (-30%).

A link-only build (rm build-pygamer/firmware.elf; make -j...) improved
from1 17.4s to 5.1s (-70%)

The size of the resulting firmware is unchanged.

Boards that are nearly full use "-flto-partition=one" to improve code
size optimization. When LTO partition is "one", this feature doesn't help
but it doesn't seem to negatively affect anything either (tested
building trinket_m0)

Jared Hancock b3cd41dd4b py/lexer: Allow conversion specifiers in f-strings (e.g. !r).
PEP-498 allows for conversion specifiers like !r and !s to convert the
expression declared in braces to be passed through repr() and str()
respectively.

This updates the logic that detects the end of the expression to also stop
when it sees "![rs]" that is either at the end of the f-string or before
the ":" indicating the start of the format specifier. The "![rs]" is now
retained in the format string, whereas previously it stayed on the end
of the expression leading to a syntax error.

Previously: `f"{x!y:z}"` --> `"{:z}".format(x!y)`
Now: `f"{x!y:z}"` --> `"{!y:z}".format(x)`

Note that "!a" is not supported by `str.format` as MicroPython has no
`ascii()`, but now this will raise the correct error.

Updated cpydiff and added tests.

David Lechner b02a5fa10a py/nlraarch64: Fix dangerous use of input register.
Starting with 2757acf6, the `top` variable in `nlr_jump()` in
`nlraarch64.c` was assigned to register `x19` by the compiler.  However,
the assembly code writes over that register with

    ldp x19, x20, [%0,  #32]

since `%0` is now `x19`. This causes the next line

    ldp lr,  x9,  [%0,  #16]

to load the wrong values.

To fix the issue, we move the value of the `top` variable from an unknown
register to a known register at the beginning of the asm code then only use
known/hard-coded registers after that.

This allows `sys.path = [...]`, which can be simpler in many cases, but

It also allows sys.path to be set to a tuple which means that you can
clear sys.path (e.g. temporarily) with no allocations.

This also makes sys.path (and sys.argv for consistency) able to be disabled

Slim down stack frames
This reduces the stack frame size of mp_builtin___import__ by
limiting the support path length of files from 256 to 96. This
function can be called recursively for nested imports so it adds up.

Also reduce mp_execute_bytecode (vm.c) from 206 a bc call to 124.
This too is recursive and adds up. It is reduced by preventing
some inlining. It may decrease performance slightly when importing
and unpacking.

Adds two new scripts for debugging. One is used from gdb to print
frame sizes in a backtrace. The other prints what pcs use a
particular stack offset. This helps find infrequently used stack
space.

David Grayson a79a6ab364 py/builtinimport: Remove partially-loaded modules from sys.modules.
Prior to this commit, importing a module that exists but has a syntax error
or some other problem that happens at import time would result in a
potentially-incomplete module object getting added to sys.modules.
Subsequent imports would use that object, resulting in confusing error
messages that hide the root cause of the problem.

This commit fixes that issue by removing the failed module from sys.modules
using the new NLR callback mechanism.

Note that it is still important to add the module to sys.modules while the
import is happening so that we can support circular imports just like
CPython does.

Damien George 2757acf6ed py/nlr: Implement jump callbacks.
NLR buffers are usually quite large (use lots of C stack) and expensive to
push and pop.  Some of the time they are only needed to perform clean up if
an exception happens, and then they re-raise the exception.

This commit allows optimizing that scenario by introducing a linked-list of
NLR callbacks that are called automatically when an exception is raised.
They are essentially a light-weight NLR handler that can implement a
"finally" block, i.e. clean-up when an exception is raised, or (by passing
`true` to nlr_pop_jump_callback) when execution leaves the scope.

Jim Mussared ed90f30dd5 py/builtinimport: Allow builtin modules to be packages.
To use this:
 - Create a built-in module, and add the module object as a member of the
   parent module's globals dict.
 - The submodule can set its `__name__` to either `QSTR_foo_dot_bar` or
   `QSTR_bar`. The former requires using qstrdefs(port).h to make the qstr.

Because `bar` is a member of `foo`'s globals, it is possible to write
`import foo` and then immediately use `foo.bar` without importing it
explicitly. This means that if `bar` has an `__init__`, it will not be
called in this situation, and for that reason, sub-modules should not have
`__init__` methods. If this is required, then all initalisation for
sub-modules should be done by the top-level module's (i.e. `foo`'s)
`__init__` method.

Jim Mussared 525557738c py/builtinimport: Optimise sub-package loading.
This makes it so that sub-packages are resolved relative to their parent's
`__path__`, rather than re-resolving each parent's filesystem path.

The previous behavior was that `import foo.bar` would first re-search
`sys.path` for `foo`, then use the resulting path to find `bar`.

For already-loaded and u-prefixed modules, because we no longer need to
build the path from level to level, we no longer unnecessarily search
the filesystem. This should improve startup time.

Explicitly makes the resolving process clear:
 - Loaded modules are returned immediately without touching the filesystem.
 - Exact-match of builtins are also returned immediately.
 - Then the filesystem search happens.
 - If that fails, then the weak-link handling is applied.

This maintains the existing behavior: if a user writes `import time` they
will get time.py if it exits, otherwise the built-in utime. Whereas `import
utime` will always return the built-in.

This also fixes a regression from a7fa18c203
where we search the filesystem for built-ins. It is now only possible to
override u-prefixed builtins. This will remove a lot of filesystem stats
at startup, as micropython-specific modules (e.g. `pyb`) will no longer
attempt to look at the filesystem.

Added several improvements to the comments and some minor renaming and
refactoring to make it clearer how the import mechanism works. Overall
code size diff is +56 bytes on STM32.

If sys.path is enabled, but empty, this will now no longer search the

CPython.

This also provides an alternative mechanism to the u-prefix to force an
import of a builtin module:

import sys
_path = sys.path[:]
sys.path.clear()
import foo  # Forces the built-in foo.
sys.path.extend(_path)
del _path

Damien George 1b980c9dbe py/compile: Remove over-eager optimisation of tuples as if condition.
When a tuple is the condition of an if statement, it's only possible to
optimise that tuple away when it is a constant tuple (ie all its elements
are constants), because if it's not constant then the elements must be
evaluated in case they have side effects (even though the resulting tuple
will always be "true").

The code before this change handled the empty tuple OK (because it doesn't
need to be evaluated), but it discarded non-empty tuples without evaluating
them, which is incorrect behaviour (as show by the updated test).

This optimisation is anyway rarely applied because it's not common Python
coding practice to write things like `if (): ...` and `if (1, 2): ...`, so
removing this optimisation completely won't affect much code, if any.

Furthermore, when MICROPY_COMP_CONST_TUPLE is enabled, constant tuples are
already optimised by the parser, so expression with constant tuples like
`if (): ...` and `if (1, 2): ...` will continue to be optimised properly
(and so when this option is enabled the code that's deleted in this commit
is actually unreachable when the if condition is a constant tuple).

Damien George d54208a2ff py/scheduler: Implement VM abort flag and mp_sched_vm_abort().
This is intended to be used by the very outer caller of the VM/runtime.  It
allows setting a top-level NLR handler that can be jumped to directly, in
order to forcefully abort the VM/runtime.

Enable using:

    #define MICROPY_ENABLE_VM_ABORT (1)

Set up the handler at the top level using:

    nlr_buf_t nlr;
    nlr.ret_val = NULL;
    if (nlr_push(&nlr) == 0) {
        nlr_set_abort(&nlr);
        // call into the VM/runtime
        ...
        nlr_pop();
    } else {
        if (nlr.ret_val == NULL) {
            // handle abort
            ...
        } else {
            // handle other exception that propagated to the top level
            ...
        }
    }
    nlr_set_abort(NULL);

Schedule an abort, eg from an interrupt handler, using:

    mp_sched_vm_abort();

Damien George 7c1584aef1 py/compile: Fix scope of assignment expression target in comprehensions.
When := is used in a comprehension the target variable is bound to the
parent scope, so it's either a global or a nonlocal.  Prior to this commit
that was handled by simply using the parent scope's id_info for the
target variable.  That's completely wrong because it uses the slot number
for the parent's Python stack to store the variable, rather than the slot
number for the comprehension.  This will in most cases lead to incorrect
behaviour or memory faults.

This commit fixes the scoping of the target variable by explicitly
declaring it a global or nonlocal, depending on whether the parent is the
global scope or not.  Then the id_info of the comprehension can be used to
access the target variable.  This fixes a lot of cases of using := in a
comprehension.

Prior to this fix, pow(1.5, inf) and pow(0.5, -inf) (among other things)
would incorrectly raise a ValueError, because the result is inf with the
first argument being finite.  This commit fixes this by allowing the result
to be infinite if the first or second (or both) argument is infinite.

This fix doesn't affect the other three math functions that have two
arguments:
- atan2 never returns inf, so always fails isinf(ans)
- copysign returns inf only if the first argument x is inf, so will never
  reach the isinf(y) check
- fmod never returns inf, so always fails isinf(ans)

Fix several places where an exception could be chained wrongly
If an exception's chain or context can refer to a pointer from a different

This couldn't turn up on UNIX testing because the VM is never torn

Because in the 'static' case the GeneratorObject is now fully initialized
whenever it's raised, the initialization can be dropped, which reduces

This ensures that all builds unconditionally run makeversionhdr.py and

This now matches the Makefile behavior, and in particular this fixes the
issue on ESP32 builds that changes in code-to-be-frozen will cause the
build to update. Both these already tools know not to touch their output
if there is no change.

Alex Riesen abaa4abd2d py: Add parenthesis to default impl of MP_OBJ_TO_PTR, MP_OBJ_FROM_PTR.
Unless MICROPY_OBJ_REPR == MICROPY_OBJ_REPR_D, these macros only work with
values and "->"/"." expressions as their sole argument.  In other words,
the macros are broken with expressions which contain operations of lower
precedence than the cast operator.

Depending on situation, the old code either results in compiler error:

 MP_OBJ_TO_PTR(flag ? o1 : o2) expands into "(void *)flag ? o1 : o2",
 which some compiler configurations will reject (e.g. GCC -Wint-conversion
 -Wint-to-pointer-cast -Werror)

Or in an incorrect address calculation:

 For ptr declared as "uint8_t *" the MP_OBJ_FROM_PTR(ptr + off)
 expands into ((mp_obj_t)ptr) + off, resulting in an obviously
 wrong address.

Jeff Epler 9f434dd8de py/gc: Ensure a gap of one byte after the ATB.
Prior to this fix the follow crash occurred.  With a GC layout of:

    GC layout:
      alloc table at 0x3fd80428, length 32001 bytes, 128004 blocks
      finaliser table at 0x3fd88129, length 16001 bytes, 128008 blocks
      pool at 0x3fd8bfc0, length 2048064 bytes, 128004 blocks

Block 128003 is an AT_HEAD and eventually is passed to gc_mark_subtree.
This causes gc_mark_subtree to call ATB_GET_KIND(128004).  When block 1 is
created with a finaliser, the first byte of the finaliser table becomes
0x2, but ATB_GET_KIND(128004) reads these bits as AT_TAIL, and then
gc_mark_subtree references past the end of the heap, which happened to be
past the end of PSRAM on the esp32-s2.

The fix in this commit is to ensure there is a one-byte gap after the ATB
filled permanently with AT_FREE.

Fixes issue #7116.

Damien George 2283b6d68f py: Pass in address to compiled module instead of returning it.
This change makes it so the compiler and persistent code loader take a
mp_compiled_module_t* as their last argument, instead of returning this
struct.  This eliminates a duplicate context variable for all callers of
these functions (because the context is now stored in the
mp_compiled_module_t by the caller), and also eliminates any confusion
about which context to use after the mp_compile_to_raw_code or
mp_raw_code_load function returns (because there is now only one context,
that stored in mp_compiled_module_t.context).

Add adafruit_pixelmap.PixelMap
.. a fast helper for animations. It is similar to and inspired by the
PixelMap helper in Adafruit LED Animation library, but with an extremely
fast 'paste' method for setting a series of pixels. This is a common
operation for many animations, and can give a substantial speed improvement.

It's named `adafruit_pixelmap` so that we can package a compatible version
in pure Python for systems that can't fit it in C in flash, or for
Blinka.

This is a proof of concept and can make a very fast comet animation:
```python
import time
import adafruit_pixelbuf
import adafruti_pixelmap
import board
import neopixel
from supervisor import ticks_ms
from adafruit_led_animation.animation.solid import Solid
from adafruit_led_animation import color

pixel_pin = board.GP0
pixel_num = 96

pixels = neopixel.NeoPixel(pixel_pin, pixel_num, brightness=1, auto_write=False, pixel_order="RGB")

evens = adafruit_pixelmap.PixelMap(pixels, tuple(range(0, pixel_num, 2)))
odd_indices = tuple((i, i+2) for i in range(1, pixel_num, 4))
print(odd_indices)
odds = adafruit_pixelbuf.PixelMap(pixels, odd_indices)
assert len(odds) == len(odd_indices)


comet_length = 16

comet1 = [color.calculate_intensity(color.GREEN, ((1+i) / comet_length) ** 2.4)
        for i in range(comet_length)]
comet2 = [color.calculate_intensity(color.PURPLE, ((1+i) / comet_length) ** 2.4)
        for i in range(comet_length)]

pos1 = 0
pos2 = 96//4

while True:
    evens.paste(comet1, pos1, wrap=True, reverse=False, others=0)
    pos1 = (pos1 + 1) % len(evens)

    odds.paste(comet2, pos2, wrap=True, reverse=True, others=0)
    pos2 = (pos2 - 1) % len(odds)
    pixels.show()

    m = ticks_ms()
    if m % 2000 > 1000:

There are two calls to mp_builtin___import__():
1. ports/unix/main.c:main_() which provides a str in args[0]
2. py/runtime.c:mp_import_name() which provides a qstr in args[0]

The default implementation of mp_builtin___import__() is
mp_builtin___import___default() which has a different implementation based
on MICROPY_ENABLE_EXTERNAL_IMPORT.

If MICROPY_ENABLE_EXTERNAL_IMPORT is disabled then the handling of weak
links assumes that args[0] is a `const char *`, when it is either a str or
qstr object.

Use the existing qstr of the module name instead, and also use a vstr
instead of strcpy() to ensure no overflow occurs.

Jim Mussared 1ba0e8ff96 py/persistentcode: Only emit sub-version if generated code has native.
In order for v1.19.1 to load a .mpy, the formerly-feature-flags which are
now used for the sub-version must be zero.

The sub-version is only used to indicate a native version change, so it
should be zero when emitting bytecode-only .mpy files.

David Lechner ab317a0d66 py/misc: Remove use of bitfield from vstr_t.
Since there is only one flag, we don't need to use a bitfield in vstr_t.
Compilers emit extra instructions to access a bitfield, so this should
reduce the binary size a small amount.

Jim Mussared d6d8722558 extmod: Make extmod.mk self-contained.
This makes it so that all a port needs to do is set the relevant variables
and "include extmod.mk" and doesn't need to worry about adding anything to
OBJ, CFLAGS, SRC_QSTR, etc.

Make all extmod variables (src, flags, etc) private to extmod.mk.

Also move common/shared, extmod-related fragments (e.g. wiznet, cyw43,
bluetooth) into extmod.mk.

Now that SRC_MOD, CFLAGS_MOD, CXXFLAGS_MOD are unused by both extmod.mk
(and user-C-modules in a previous commit), remove all uses of them from
port makefiles.

Angus Gratton 25ff5b52d9 py/parse: Allow const types other than int to optimise as true/false.
Allows optimisation of cases like:

    import micropython
    _DEBUG = micropython.const(False)
    if _DEBUG:
        print('Debugging info')

Previously the 'if' statement was only optimised out if the type of the
const() argument was integer.

The change is implemented in a way that makes the compiler slightly smaller
(-16 bytes on PYBV11) but compilation will also be very slightly slower.

As a bonus, if const support is enabled then the compiler can now optimise
const truthy/falsey expressions of other types, like:

    while "something":
        pass

... unclear if that is useful, but perhaps it could be.

- When saving a .mpy file that can't be opened it now raises an exception
  (prior, it would silently fail), and includes the filename in the

Jim Mussared d94141e147 py/persistentcode: Introduce .mpy sub-version.
The intent is to allow us to make breaking changes to the native ABI (e.g.
changes to dynruntime.h) without needing the bytecode version to increment.

With this commit the two bits previously used for the feature flags (but
now unused as of .mpy version 6) encode a sub-version.  A bytecode-only
.mpy file can be loaded as long as MPY_VERSION matches, but a native .mpy
(i.e. one with an arch set) must also match MPY_SUB_VERSION.  This allows 3
additional updates to the native ABI per bytecode revision.

The sub-version is set to 1 because the previous commits that changed the
layout of mp_obj_type_t have changed the native ABI.

The check for make_new (i.e. used to determine something's type) is now

Jim Mussared 94beeabd2e py/obj: Convert make_new into a mp_obj_type_t slot.
Instead of being an explicit field, it's now a slot like all the other
methods.

This is a marginal code size improvement because most types have a make_new
(100/138 on PYBV11), however it improves consistency in how types are
declared, removing the special case for make_new.
