Jim Mussared a652695153 tests/multi_bluetooth/ble_mtu: Split peripheral/central-initiated.

Damien George af42634866 tests/run-multitests.py: Support outputting test metrics.
If a multitest calls `multitest.output_metric(...)` then that output will
be collected separately, not considered as part of the test verification
output, and instead be printed at the end.  This is useful for tests that
want to output performance/timing metrics that may change from one run to
the next.

Jeremy Rand d677023b3d extmod/vfs_posix: Do not filter '..*' in ilistdir when filtering '..'.
When iterating over os.ilistdir(), the special directories '.' and '..'
are filtered from the results.  But the code inadvertently also filtered
any file/directory which happened to match '..*'.  This change fixes the
filter.

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.

Damien George 2e4dda3c20 py/modmath: Fix two-argument math function domain check.
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)

Damien Tournoud ed58d6e4ce extmod/modussl_mbedtls: Fix support for ioctl(MP_STREAM_POLL).
During the initial handshake or subsequent renegotiation, the protocol
might need to read in order to write (or conversely to write in order
to read). It might be blocked from doing so by the state of the
underlying socket (i.e. there is no data to read, or there is no space
to write).

The library indicates this condition by returning one of the errors
`MBEDTLS_ERR_SSL_WANT_READ` or `MBEDTLS_ERR_SSL_WANT_WRITE`. When that
happens, we need to enforce that the next poll operation only considers
the direction that the library indicated.

In addition, mbedtls does its own read buffering that we need to take
into account while polling, and we need to save the last error between
read()/write() and ioctl().

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.

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.

Jim Mussared 6da41b5900 py/obj: Merge getiter and iternext mp_obj_type_t slots.
The goal here is to remove a slot (making way to turn make_new into a slot)
as well as reduce code size by the ~40 references to mp_identity_getiter
and mp_stream_unbuffered_iter.

This introduces two new type flags:
- MP_TYPE_FLAG_ITER_IS_ITERNEXT: This means that the "iter" slot in the
  type is "iternext", and should use the identity getiter.
- MP_TYPE_FLAG_ITER_IS_CUSTOM: This means that the "iter" slot is a pointer
  to a mp_getiter_iternext_custom_t instance, which then defines both
  getiter and iternext.

And a third flag that is the OR of both, MP_TYPE_FLAG_ITER_IS_STREAM: This
means that the type should use the identity getiter, and
mp_stream_unbuffered_iter as iternext.

Finally, MP_TYPE_FLAG_ITER_IS_GETITER is defined as a no-op flag to give
the default case where "iter" is "getiter".

Andrew Leech 4e0964b59f extmod/vfs: Add finaliser to ilistdir to close directory handle.
When iterating over filesystem/folders with os.iterdir(), an open file
(directory) handle is used internally.  Currently this file handle is only
closed once the iterator is completely drained, eg. once all entries have
been looped over / converted into list etc.

If a program opens an iterdir but does not loop over it, or starts to loop
over the iterator but breaks out of the loop, then the handle never gets
closed.  In this state, when the iter object is cleaned up by the garbage
collector this open handle can cause corruption of the filesystem.

and pre-emptively draw them then.

This adds 72 bytes on PYBV11, but makes filled poly() 20% faster.

Mat Booth 04a655c744 extmod/modframebuf: Add polygon drawing methods.
Add method for drawing polygons.

For non-filled polygons, uses the existing line-drawing code to render
arbitrary polygons using the given coords list, at the given x,y position,
in the given colour.

For filled polygons, arbitrary closed polygons are rendered using a fast
point-in-polygon algorithm to determine where the edges of the polygon lie
on each pixel row.

Tests and documentation updates are also included.

Dan Ellis 6f4d424f46 py/formatfloat: Use pow(10, e) instead of pos/neg_pow lookup tables.
Rework the conversion of floats to decimal strings so it aligns precisely
with the conversion of strings to floats in parsenum.c.  This is to avoid
rendering 1eX as 9.99999eX-1 etc.  This is achieved by removing the power-
of-10 tables and using pow() to compute the exponent directly, and that's
done efficiently by first estimating the power-of-10 exponent from the
power-of-2 exponent in the floating-point representation.

Code size is reduced by roughly 100 to 200 bytes by this commit.

Ned Konz 5543b2a9cc extmod/uasyncio: Add clear method to ThreadSafeFlag.
This is useful in situations where the ThreadSafeFlag is reused and needs
to be cleared of any previous, unwanted event.

For example, clear the flag at the start of an operation, trigger the
operation (eg an I2C write), then (a)wait for an external event to set the
flag (eg a pin IRQ).  Further events may trigger the flag again but these
are unwanted and should be cleared before the next cycle starts.

Andrew Leech f7f56d4285 py/objstr: Consolidate methods for str/bytes/bytearray/array.
This commit adds the bytes methods to bytearray, matching CPython.  The
existing implementations of these methods for str/bytes are reused for
bytearray with minor updates to match CPython return types.

For details on the CPython behaviour see

The work to merge locals tables for str/bytes/bytearray/array was done by

David Lechner 6baeded322 py/runtime: Fix crash in star arg unpacking.
The reallocation trigger for unpacking star args with unknown length
did not take into account the number of fixed args remaining. So it was
possible that the unpacked iterators could take up exactly the memory
allocated then nothing would be left for fixed args after the star args.
This causes a segfault crash.

This is fixed by taking into account the remaining number of fixed args
in the check to decide whether to realloc yet or not.

Formerly, py/formatfloat would print whole numbers inaccurately with

until the value is smaller than 1, so all whole numbers print with zero
fractional part.

Damien George 4fe3e493b1 py/obj: Make mp_obj_get_complex_maybe call mp_obj_get_float_maybe first.
This commit simplifies mp_obj_get_complex_maybe() by first calling
mp_obj_get_float_maybe() to handle the cases corresponding to floats.
Only if that fails does it attempt to extra a full complex number.

This reduces code size and also means that mp_obj_get_complex_maybe() now
supports user-defined classes defining __float__; in particular this allows
user-defined classes to be used as arguments to cmath-module function.

Furthermore, complex_make_new() can now be simplified to directly call
mp_obj_get_complex(), instead of mp_obj_get_complex_maybe() followed by
mp_obj_get_float().  This also improves error messages from complex with
an invalid argument, it now raises "can't convert <type> to complex" rather
than "can't convert <type> to float".

Support for architecture-specific qstr linking was removed in
d4d53e9e11, where native code was changed to
access qstr values via qstr_table.  The only remaining use for the special

C, linked via mpy_ld.py.  But native modules can also use the standard

This commit removes the remaining native qstr liking support in
persistentcode.c's load_raw_code function, and adds two new relocation
options for constants.qstr_table and constants.obj_table.  mpy_ld.py is

Prior to this commit, all qstrs were required to be allocated (by calling
mp_emit_common_use_qstr) in the MP_PASS_SCOPE pass (the first one).  But
this is an unnecessary restriction, which is lifted by this commit.
Lifting the restriction simplifies the compiler because it can allocate
qstrs in later passes.

This also generates better code, because in some cases (eg when a variable
is closed over) the scope of an identifier is not known until a bit later
and then the identifier no longer needs its qstr allocated in the global
table.

Damien George c49d5207e9 py/persistentcode: Remove unicode feature flag from .mpy file.
Prior to this commit, even with unicode disabled .py and .mpy files could
contain unicode characters, eg by entering them directly in a string as
utf-8 encoded.

The only thing the compiler disallowed (with unicode disabled) was using
\uxxxx and \Uxxxxxxxx notation to specify a character within a string with
value >= 0x100; that would give a SyntaxError.

With this change mpy-cross will now accept \u and \U notation to insert a
character with value >= 0x100 into a string (because the -mno-unicode
option is now gone, there's no way to forbid this).  The runtime will
happily work with strings with such characters, just like it already works
with strings with characters that were utf-8 encoded directly.

This change simplifies things because there are no longer any feature
flags in .mpy files, and any bytecode .mpy will now run on any target.

Damien George 35c0cff92b py/parse: Add MICROPY_COMP_CONST_TUPLE option to build const tuples.
This commit adds support to the parser so that tuples which contain only
constant elements (bool, int, str, bytes, etc) are immediately converted to
a tuple object.  This makes it more efficient to use tuples containing
constant data because they no longer need to be created at runtime by the
bytecode (or native code).

Furthermore, with this improvement constant tuples that are part of frozen
code are now able to be stored fully in ROM (this will be implemented in
later commits).

Code size is increased by about 400 bytes on Cortex-M4 platforms.

See related issue #722.

Damien George bd556b6996 py: Fix compiling and decoding of *args at large arg positions.
There were two issues with the existing code:

1. "1 << i" is computed as a 32-bit number so would overflow when
   executed on 64-bit machines (when mp_uint_t is 64-bit).  This meant that
   *args beyond 32 positions would not be handled correctly.

2. star_args must fit as a positive small int so that it is encoded
   correctly in the emitted code.  MP_SMALL_INT_BITS is too big because it
   overflows a small int by 1 bit.  MP_SMALL_INT_BITS - 1 does not work
   because it produces a signed small int which is then sign extended when
   extracted (even by mp_obj_get_int_truncated), and this sign extension
   means that any position arg after *args is also treated as a star-arg.
   So the maximum bit position is MP_SMALL_INT_BITS - 2.  This means that
   MP_OBJ_SMALL_INT_VALUE() can be used instead of
   mp_obj_get_int_truncated() to get the value of star_args.

These issues are fixed by this commit, and a test added.

David Lechner 47685180f0 tests/basics/fun_callstardblstar: Add coverage test.
This fixes code coverage for the case where a *arg without __len__ is
unpacked and uses exactly the amount of memory that was allocated for
kw args. This triggers the code branch where the memory for the kw args
gets reallocated since it was used already by the *arg unpacking.

David Lechner 783b1a868f py/runtime: Allow multiple *args in a function call.
This is a partial implementation of PEP 448 to allow unpacking multiple
star args in a function or method call.

This is implemented by changing the emitted bytecodes so that both
positional args and star args are stored as positional args.  A bitmap is
added to indicate if an argument at a given position is a positional
argument or a star arg.

In the generated code, this new bitmap takes the place of the old star arg.
It is stored as a small int, so this means only the first N arguments can
be star args where N is the number of bits in a small int.

The runtime is modified to interpret this new bytecode format while still
trying to perform as few memory reallocations as possible.

David Lechner 1e99d29f36 py/runtime: Allow multiple **args in a function call.
This is a partial implementation of PEP 448 to allow multiple ** unpackings
when calling a function or method.

The compiler is modified to encode the argument as a None: obj key-value
pair (similar to how regular keyword arguments are encoded as str: obj
pairs).  The extra object that was pushed on the stack to hold a single **
unpacking object is no longer used and is removed.

The runtime is modified to decode this new format.
