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.

Uncrustify versions are not mutually compatible:
1. Version 0.73 or newer produce slightly different formatting. It may be
possible to tweak these by adding more config items, but this will cause
older versions to error out with 'Unknown option'.
2. Version 0.75 prints a range of deprecation warnings due to config file
changes, and returns a non-zero exit code. These are actually fixable
as most are the default value, and pp_indent has changed from 'true' to '1'
which is backwards compatible. However issue 1 remains, so probably better

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.

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.

The metadata can be version, description, and license.
After executing a manifest, the top-level metadata can be queried, and also
each file output from the manifest will have the metadata of the
containing manifest.
Use the version metadata to "tag" files before freezing such that they have
__version__ available.
By default, don't include micropython-lib/unix-ffi in the search.
If unix_ffi=True is passed to require(), then include unix-ffi and make it
take precedence over the other locations (e.g. python-stdlib).
This does two things:
- Prevents non-unix builds from using unix-only packages.
- Allows the unix build to optionally use a more full-featured (e.g. ffi)

Now that the native qstr link table is gone, merging a native .mpy file
with a bytecode .mpy file is not as simple as concatenating the .mpy data.
The qstr_table and obj_table tables from all merged .mpy files must now be
joined together, because they are global to the .mpy file (and hence global
to the merged .mpy file). This means the bytecode needs to be be decoded,
qstr_table and obj_table indices updated to point to the correct entries in
the new tables, and then the bytecode re-encoded.
This commit makes this change to the merging feature in mpy-tool.py. This

This commit removes the remaining native qstr liking support in

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).
Code size change for those ports that enable the native emitter:
unix x64: +80 +0.015%
stm32: +24 +0.004% PYBV10
esp8266: +88 +0.013% GENERIC
esp32: -20 -0.002% GENERIC[incl -112(data)]

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.

Specifying the option `--unsafe-links` (or `-l`) to `mpremote mount` will
allow symlinks to be followed in the local directory that point outside of
the base directory path.
For the unsafe case the `path_check()` method of `PyboardCommand` still
checks for a common path but without expanding symlinks. While this check
is currently redundant, it makes the purpose of the method clearer for
possible future uses or extensions.
With the existing code problems can occur with remounting, the "if t -
t_last_activity > QUIET_TIMEOUT:" check can be triggered early before the
REPL string comes through, meaning that the remount doesn't happen.
On certain boards the "MPY: soft reboot" line comes through immediately
(getting the routine past initial timeout) but then there's a slightly
longer delay while the board restarts before it prints out the startup
header and the REPL prompt.
This commit adds some extra pattern monitoring during the timeout loop to
track the state if a soft restart is actually started.
These jumps are always forwards, and it's more efficient in the VM to
decode an unsigned argument. These opcodes are already optimised versions
of the sequence "dup-top pop-jump-if-x pop" so it doesn't hurt generality
to optimise them further.

This commit introduces changes:
- All jump opcodes are changed to have variable length arguments, of either
1 or 2 bytes (previously they were fixed at 2 bytes). In most cases only
1 byte is needed to encode the short jump offset, saving bytecode size.
- The bytecode emitter now selects 1 byte jump arguments when the jump
offset is guaranteed to fit in 1 byte. This is achieved by checking if
the code size changed during the last pass and, if it did (if it shrank),
then requesting that the compiler make another pass to get the correct
offsets of the now-smaller code. This can continue multiple times until
the code stabilises. The code can only ever shrink so this iteration is
guaranteed to complete. In most cases no extra passes are needed, the
original 4 passes are enough to get it right by the 4th pass (because the
2nd pass computes roughly the correct labels and the 3rd pass computes
the correct size for the jump argument).
This change to the jump opcode encoding reduces .mpy files and RAM usage
(when bytecode is in RAM) by about 2% on average.
The performance of the VM is not impacted, at least within measurment of
the performance benchmark suite.
Code size is reduced for builds that include a decent amount of frozen
bytecode. ARM Cortex-M builds without any frozen code increase by about
350 bytes.

Background: .mpy files are precompiled .py files, built using mpy-cross,
that contain compiled bytecode functions (and can also contain machine
code). The benefit of using an .mpy file over a .py file is that they are
faster to import and take less memory when importing. They are also
smaller on disk.
But the real benefit of .mpy files comes when they are frozen into the
firmware. This is done by loading the .mpy file during compilation of the
firmware and turning it into a set of big C data structures (the job of
mpy-tool.py), which are then compiled and downloaded into the ROM of a
device. These C data structures can be executed in-place, ie directly from
ROM. This makes importing even faster because there is very little to do,
and also means such frozen modules take up much less RAM (because their
bytecode stays in ROM).
The downside of frozen code is that it requires recompiling and reflashing
the entire firmware. This can be a big barrier to entry, slows down
development time, and makes it harder to do OTA updates of frozen code
(because the whole firmware must be updated).
This commit attempts to solve this problem by providing a solution that
sits between loading .mpy files into RAM and freezing them into the
firmware. The .mpy file format has been reworked so that it consists of
data and bytecode which is mostly static and ready to run in-place. If
these new .mpy files are located in flash/ROM which is memory addressable,
the .mpy file can be executed (mostly) in-place.
With this approach there is still a small amount of unpacking and linking
of the .mpy file that needs to be done when it's imported, but it's still
much better than loading an .mpy from disk into RAM (although not as good
as freezing .mpy files into the firmware).
The main trick to make static .mpy files is to adjust the bytecode so any
qstrs that it references now go through a lookup table to convert from
local qstr number in the module to global qstr number in the firmware.
That means the bytecode does not need linking/rewriting of qstrs when it's
loaded. Instead only a small qstr table needs to be built (and put in RAM)
at import time. This means the bytecode itself is static/constant and can
be used directly if it's in addressable memory. Also the qstr string data
in the .mpy file, and some constant object data, can be used directly.
Note that the qstr table is global to the module (ie not per function).
In more detail, in the VM what used to be (schematically):
qst = DECODE_QSTR_VALUE;
is now (schematically):
idx = DECODE_QSTR_INDEX;
qst = qstr_table[idx];
That allows the bytecode to be fixed at compile time and not need
relinking/rewriting of the qstr values. Only qstr_table needs to be linked
when the .mpy is loaded.
Incidentally, this helps to reduce the size of bytecode because what used
to be 2-byte qstr values in the bytecode are now (mostly) 1-byte indices.
If the module uses the same qstr more than two times then the bytecode is
smaller than before.
The following changes are measured for this commit compared to the
previous (the baseline):
- average 7%-9% reduction in size of .mpy files
- frozen code size is reduced by about 5%-7%
- importing .py files uses about 5% less RAM in total
- importing .mpy files uses about 4% less RAM in total
- importing .py and .mpy files takes about the same time as before
The qstr indirection in the bytecode has only a small impact on VM
performance. For stm32 on PYBv1.0 the performance change of this commit
is:

As part of this change the .mpy file format version is bumped to version 6.
And mpy-tool.py has been improved to provide a good visualisation of the
contents of .mpy files.
In summary: this commit changes the bytecode to use qstr indirection, and
reworks the .mpy file format to be simpler and allow .mpy files to be
executed in-place. Performance is not impacted too much. Eventually it
will be possible to store such .mpy files in a linear, read-only, memory-
mappable filesystem so they can be executed from flash/ROM. This will
essentially be able to replace frozen code for most applications.

This changes the git commit message line length check to ignore lines that
contain URLs, since these cannot be wrapped without breaking tools that
detect URLs and create a link.

This allows the compiler to merge strings: e.g. "update",
"difference_update" and "symmetric_difference_update" will all point to the
same memory.
No functional change.
The size reduction depends on the number of qstrs in the build. The change
this commit brings is:

Performance is also improved (on bare metal at least) for the
core_import_mpy_multi.py, core_import_mpy_single.py and core_qstr.py
performance benchmarks.

Changes are:
- decision to remount local filesystem on remote device is made only if
"MPY: soft reboot" is seen in the output after sending a ctrl-D
- a nice message is printed to the user when the remount occurs
- soft reset during raw REPL is now handled correctly
Fixes issue #7731.

A backslash in the directory name will end up being passed through to the
device and becoming a backslash in a filename, rather than being
interpreted as directories. This makes "cp -r" problematic on Windows.
Changing to simply "/",join() fixes this.
As a prerequisite to upgrading to Zephyr v2.7.0, upgrade CI to use
Zephyr docker image v0.21.0. In particular, this is needed to pick up a
newer CMake version because Zephyr v2.7.0 increased the minimum CMake
version required to 3.20.0.

This allows the remote MicroPython instance to create and delete
directories from the mounted host filesystem in addition to the already
existing functionality of reading, creating, and modifying files.

This changes makemanifest.py & mpy-tool.py to merge string and mpy names
into the same list (now mp_frozen_names).
The various paths for loading a frozen module (mp_find_frozen_module) and
checking existence of a frozen module (mp_frozen_stat) use a common
function that searches this list.
In addition, the frozen lookup will now only take place if the path starts
with ".frozen", which needs to be added to sys.path.
This fixes issues #1804, #2322, #3509, #6419.

Any board with a board.json file will be built. ESP32-based boards will be
built using the IDF at $IDF_PATH_V42, all other MCU variants (S2, S3, C3)
will be built using the IDF at $IDF_PATH_V44.

Any board with a board.json file will be built. Additional variants for
certain pyboards will also be built by the explicit build-stm32-extra.sh
script. Both .dfu and .hex files will be made available.
Also build boards in a sorted order, and don't stop building if a single
board fails.

This is to make the builds for all nucleo/discovery boards uniform, so they
can be treated the same by the auto build scripts.
The CI script is updated to explicitly enable mboot and packing, to test
these features.

There is no release of IDF v4.4 yet but master is now on v5.0-dev so a
specific commit must be chosen to stick to v4.4.
