Binaries built using the Make build system now no longer appear in the
working directory of the build, but rather in the build directory. Thus
some paths had to be adjusted.
The rules for lib (static library with name $(LIBMICROPYTHON)) and the
default rule to build a binary (name $(PROG)) produced outputs in the
current working directory. Change this to build these files in the build
directory.
Note: An empty BUILD variable can cause issues (references to the root
directory); this is not addressed by this commit due to multiple other
places having the same issue.
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
nonzero digits beyond the decimal place. This resulted from its strategy
of successive scaling of the argument by 0.1 which cannot be exactly
represented in floating point. The change in this commit avoids scaling
until the value is smaller than 1, so all whole numbers print with zero
fractional part.
Fixes issue #4212.

On ports with more than one filesystem, the type will be wrong, for example
if using LFS but FAT enabled, then the type will be FAT. So it's not
possible to use these classes to identify a file object type.
Furthermore, constructing an io.FileIO currently crashes on FAT, and
make_new isn't supported on LFS.
And the io.TextIOWrapper class does not match CPython at all.

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".

This commit adds a new option MICROPY_GC_SPLIT_HEAP (disabled by default)
which, when enabled, allows the GC heap to be split over multiple memory
areas/regions. The first area is added with gc_init() and subsequent areas
can be added with gc_add(). New areas can be added at runtime. Areas are
stored internally as a linked list, and calls to gc_alloc() can be
satisfied from any area.
This feature has the following use-cases (among others):
- The ESP32 has a fragmented OS heap, so to use all (or more) of it the
GC heap must be split.
- Other MCUs may have disjoint RAM regions and are now able to use them
all for the GC heap.
- The user could explicitly increase the size of the GC heap.
- Support a dynamic heap while running on an OS, adding more heap when
necessary.

Commit d96cfd13e3 introduced a regression by breaking existing
users of mp_obj_is_type(.., &mp_obj_bool). This function (and associated
helpers like mp_obj_is_int()) have some specific nuances, and mistakes like
this one can happen again.
This commit adds mp_obj_is_exact_type() which behaves like the the old
mp_obj_is_type(). The new mp_obj_is_type() has the same prototype but it
attempts to statically assert that it's not called with types which should
be checked using mp_obj_is_type(). If called with any of these types: int,
str, bool, NoneType - it will cause a compilation error. Additional
checked types (e.g function types) can be added in the future.
Existing users of mp_obj_is_type() with the now "invalid" types, were
translated to use mp_obj_is_exact_type().
The use of MP_STATIC_ASSERT() is not bulletproof - usually GCC (and other
compilers) can't statically check conditions that are only known during
link-time (like variables' addresses comparison). However, in this case,
GCC is able to statically detect these conditions, probably because it's
the exact same object - `&mp_type_int == &mp_type_int` is detected.
Misuses of this function with runtime-chosen types (e.g:
`mp_obj_type_t *x = ...; mp_obj_is_type(..., x);` won't be detected. MSC
is unable to detect this, so we use MP_STATIC_ASSERT_NOT_MSC().
Compiling with this commit and without the fix for d96cfd13e3 shows
that it detects the problem.

This check for code_state->ip being NULL was added in
a7c02c4538 with a commit message that "When
generator raises exception, it is automatically terminated (by setting its
code_state.ip to 0)". It was also added without any tests to test for this
particular case. (The commit did mention that CPython's test_pep380.py
triggered a bug, but upon re-running this test it did not show any need for
this NULL check of code_state->ip.)
It is true that generators that have completed (either by running to their
end or raising an exception) set "code_state.ip = 0". But there is an
explicit check at the start of mp_obj_gen_resume() to return immediately
for any attempt to resume an already-stopped generator. So the VM can
never execute a generator with NULL ip (and this was true at the time of
the above-referenced commit).
Furthermore, the other parts of the VM just before and after this piece
of code do require (or at least assume) code_state->ip is non-NULL.

The optimisation that allows a single check in the VM for either a pending
exception or non-empty scheduler queue doesn't work when threading is
enabled, as one thread can clear the sched_state if it has no pending
exception, meaning the thread with the pending exception will never see it.
This removes that optimisation for threaded builds.
Also fixes a race in non-scheduler builds where get-and-clear of the
pending exception is not protected by the atomic section.
Also removes the bulk of the inlining of pending exceptions and scheduler
handling from the VM. This just costs code size and complexity at no
performance benefit.

The search in these cases should include all finally handlers that are
after the current ip. If a handler starts at exactly ip then it is
considered "after" the ip. This can happen when END_FINALLY is followed
immediately by a finally handler (from a different finally).
Consider the function:
def f():
try:
return 0
finally:
print(1)
The current bytecode emitter generates the following code:
00 SETUP_FINALLY 5
02 LOAD_CONST_SMALL_INT 0
03 RETURN_VALUE
04 LOAD_CONST_NONE ****
05 LOAD_GLOBAL print
07 LOAD_CONST_SMALL_INT 1
08 CALL_FUNCTION n=1 nkw=0
10 POP_TOP
11 END_FINALLY
12 LOAD_CONST_NONE
13 RETURN_VALUE
The LOAD_CONST_NONE marked with **** is dead code because it follows a
RETURN_VALUE, and nothing jumps to this LOAD_CONST_NONE. If the emitter
could remove this this dead code it would produce:
00 SETUP_FINALLY 4
02 LOAD_CONST_SMALL_INT 0
03 RETURN_VALUE
04 LOAD_GLOBAL print
06 LOAD_CONST_SMALL_INT 1
07 CALL_FUNCTION n=1 nkw=0
09 POP_TOP
10 END_FINALLY
11 LOAD_CONST_NONE
12 RETURN_VALUE
In this case the finally block (which starts at offset 4) immediately
follows the RETURN_VALUE. When RETURN_VALUE executes ip will point to
offset 4 in the bytecode (because the dispatch of the opcode does *ip++)
and so the finally handler will only be found if a >= comparison is used.
It's a similar story for break/continue:
while True:
try:
break
finally:
print(1)
Although technically in this case the > comparison still works because the
extra byte from the UNWIND_JUMP (encoding the number of exception handlers
to unwind) doesn't have a *ip++ (just a *ip) so ip remains pointing within
the UNWIND_JUMP opcode, and not at the start of the following finally
handler. Nevertheless, the change is made to use >= for consistency with
the RETURN_VALUE change.

This commit removes the remaining native qstr liking support in

The recent rework of bytecode made all constants global with respect to the
module (previously, each function had its own constant table). That means
the constant table for a module is shared among all functions/methods/etc
within the module.
This commit add support to the compiler to de-duplicate constants in this
module constant table. So if a constant is used more than once -- eg 1.0
or (None, None) -- then the same object is reused for all instances.
For example, if there is code like `print(1.0, 1.0)` then the parser will
create two independent constants 1.0 and 1.0. The compiler will then (with
this commit) notice they are the same and only put one of them in the
constant table. The bytecode will then reuse that constant twice in the
print expression. That allows the second 1.0 to be reclaimed by the GC,
also means the constant table has one less entry so saves a word.

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.

Some architectures (like esp32 xtensa) cannot read byte-wise from
executable memory. This means the prelude for native functions -- which is
usually located after the machine code for the native function -- must be
placed in separate memory that can be read byte-wise. Prior to this commit
this was achieved by enabling N_PRELUDE_AS_BYTES_OBJ for the emitter and
MICROPY_EMIT_NATIVE_PRELUDE_AS_BYTES_OBJ for the runtime. The prelude was
then placed in a bytes object, pointed to by the module's constant table.
This behaviour is changed by this commit so that a pointer to the prelude
is stored either in mp_obj_fun_bc_t.child_table, or in
mp_obj_fun_bc_t.child_table[num_children] if num_children > 0. The reasons
for doing this are:
1. It decouples the native emitter from runtime requirements, the emitted
code no longer needs to know if the system it runs on can/can't read
byte-wise from executable memory.
2. It makes all ports have the same emitter behaviour, there is no longer
the N_PRELUDE_AS_BYTES_OBJ option.
3. The module's constant table is now used only for actual constants in the
Python code. This allows further optimisations to be done with the
constants (eg constant deduplication).

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.
