This is necessary to access sites that only support these protocols.
The rp2 port already has ECDH enabled, so this just adds ECDSA there. The
other ports now gain both ECDH and ECDSA. The code size increase is:
- rp2 (PICO_W): +2916 bytes flash, +24 bytes BSS
- stm32 (PYBD_SF6): +20480 bytes flash, +32 bytes data, +48 bytes BSS
- mimxrt (TEENSY41): +20708 bytes flash, +32 bytes data, +48 bytes BSS
- unix (standard x86-64): +39344 executable, +1744 bytes data, +96 BSS
This is obviously a large increase in code size. But there doesn't seem to
be any other option because without elliptic curve cryptography devices are
partially cut off from the internet. For use cases that require small
firmware size, they'll need to build custom firmware with a custom mbedtls
config.

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.

The call to invoke_irq_handler_run() always needs to run in a protected NLR
context, to catch exceptions from the Python handler, and the m_new's (and
also mp_local_alloc when PYSTACK is enabled). With
MICROPY_PY_BLUETOOTH_USE_SYNC_EVENTS_WITH_INTERLOCK enabled there was
already an explicit nlr_push, and that is now used in all cases.
Without this change, on stm32 (for example), the callbacks from the BLE
stack to invoke_irq_handler() were made via static scheduled nodes which do
not have any NLR protection, and hence would lead to a hard fault (uncaught
NLR) if an exception was raised in the Python BLE IRQ handler. This was a
regression introduced by 8045ac07f5, which is
fixed by this commit.

Prevent handle leaks when file objects aren't closed explicitly and
fix some MICROPY_CPYTHON_COMPAT issues: this wasn't properly adhered
to because #ifdef was used so it was always on, and closing files
multiple times should be avoided unconditionally.
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.
Signed-off-by: Jim Mussared <jim.mussared@gmail.com>
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".

The buffer protocol type only has a single member, and this existing layout

additional slots to mp_obj_type_t or re-visit the buffer protocol then.

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.
Fixes issues #6568 and #8506.
This is technically a breaking change, but:
a) We need the end handle to do descriptor discovery properly.
b) We have no possible use for the existing definition handle in the
characteristic result IRQ. None of the methods can use it, and therefore
no existing code should be using it in a way that changing it to a
different integer value should break.
Unfortunately NimBLE doesn't make it easy to get the end handle, so also
implement a mechanism to use the following characteristic to calculate
the previous characteristic's end handle.

Since commit e65d1e69e8 there is no longer an
io.FileIO class, so this option is no longer needed.
This option also controlled whether or not files supported being opened in
binary mode (eg 'rb'), and could, if disabled, lead to confusion as to why
opening a file in binary mode silently did the wrong thing (it would just
open in text mode if MICROPY_PY_IO_FILEIO was disabled).
The various VFS implementations (POSIX, FAT, LFS) were the only places
where enabling this option made a difference, and in almost all cases where
one of these filesystems were enabled, MICROPY_PY_IO_FILEIO was also
enabled. So it makes sense to just unconditionally enable this feature
(ability to open a file in binary mode) in all cases, and so just remove
this config option altogether. That makes configuration simpler and means
binary file support always exists (and opening a file in binary mode is
arguably more fundamental than opening in text mode, so if anything should
be configurable then it should be the ability to open in text mode).

For example, clear the flag at the start of an operation, trigger 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.

Avoiding conflicts between the IRQ and an active transfers. Before this

Fix found and code supplied by @omogenot.

different epochs, and includes it in the rp2 port.
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.

The main aim of this change is to reduce the number of heap allocations
when writing data to a stream. This is done in two ways:
1. Eliminate appending of data when .write() is called multiple times
before calling .drain(). With this commit, the data is written out
immediately if the underlying stream is not blocked, so there is no
accumulation of the data in a temporary buffer.
2. Eliminate copying of non-bytes objects passed to .write(). Prior to
this commit, passing a bytearray or memoryview to .write() would always
result in a copy of it being made and turned into a bytes object. That
won't happen now if the underlying stream is not blocked.
Also, this change makes .write () more closely implement the CPython
documented semantics: "The method attempts to write the data to the
underlying socket immediately. If that fails, the data is queued in an
internal write buffer until it can be sent."
This changes the btree implementation to use the buffer protocol for
reading key/values in all methods. `str` and `bytes` objects are not the
only bytes-like objects that could be used.
Documentation and tests are also updated.

Boosted performance, board.json metadata, more mimxrt, rp2, samd features
This release of MicroPython sees a boost to the overall performance of the
VM and runtime. This is achieved by the addition of an optional cache to
speed up general hash table lookups, as well as a fast path in the VM for
the LOAD_ATTR opcode on instance types. The new configuration options are
MICROPY_OPT_MAP_LOOKUP_CACHE and MICROPY_OPT_LOAD_ATTR_FAST_PATH. As part
of this improvement the MICROPY_OPT_CACHE_MAP_LOOKUP_IN_BYTECODE option has
been removed, which provided a similar map caching mechanism but with the
cache stored in the bytecode, which made it not useful on bare metal ports.
The new mechanism is measured to be at least as good as the old one,
applies to more map lookups, has a constant RAM overhead, and applies to
native code as well as bytecode.
These performance options are enabled on the esp32, mimxrt, rp2, stm32 and
unix ports. For esp32 and mimxrt some code is also moved to RAM to further
boost performance. On stm32, performance increases by about 20% for
benchmarks that are heavy on name lookups, like misc_pystone.py and
misc_raytrace.py. On esp32 performance can increase by 2-3x, and on mimxrt
it is up to 6x.
All boards in all ports now have a board.json metadata file, which is used
to automatically build firmware and generate a webpage for that board
(among other possibilities). Auto-build scripts have been added for this
purpose and they build all esp32, mimxrt, rp2, samd and stm32 boards. The
generated output is available at https://micropython.org/download.
Support for FROZEN_DIR and FROZEN_MPY_DIR has been deprecated for some time
and was finally removed in this release. Instead of these, FROZEN_MANIFEST
can be used. The io.resource_stream() function is also removed, replaced
by the pure Python version in micropython-lib.
The search order for importing frozen Python modules is now controlled by
the ".frozen" entry in sys.path. This string is added by default in the
second position in sys.path. User code should adjust sys.path depending on
the desired behaviour. Putting ".frozen" first in sys.path will speed up
importing frozen modules.
A bug in multiple precision integers with bitwise of -0 was fixed in commit
2c139bbf4e.
The platform module has been added to allow querying the compiler and
underlying SDK/HAL/libc version. This is enabled on esp32, mimxrt and

filesystems. And a help command has been added.

second time) to the Google Season of Docs project. The rp2 documentation
now includes a reference for PIO assembly instructions, a PIO quick
reference and a PIO tutorial. The random and stm modules have been
documented, along with sys.settrace, manifest.py files and mpremote. There
is also now more detail about the differences between MicroPython and
standard Python 3.5 and above.
The esp32 port sees support for ESP32-S3 SoCs, and new boards GENERIC_S3,
ESP32_S2_WROVER, LOLIN_S2_MINI, LOLIN_S2_PICO and UM_FEATHERS2NEO. The PWM
driver has been improved and now supports all PWM timers and channels, and
the duty_u16() and duty_ns() methods, and it keeps the duty constant when
changing frequency. The machine.bitstream() function has been improved to
use RMT, with an option to select the original bit-banging implementation.
The mimxrt port gained new hardware features: SDRAM and SD card support, as
well as network integration with a LAN driver. The machine.WDT class was
added along with the machine.reset_cause(), machine.soft_reset(),
machine.unique_id() add machine.bitstream() functions. DHT sensor support
was added, and f-strings were enabled.
The rp2 port now has support for networking, and bluetooth using NimBLE.
The Nina-W10 WiFi/BT driver is fully integrated and supported by the new
Arduino Nano RP2040 connect board. I2S protocol support is added along
with a machine.bitstream() driver and DHT sensor support. The PWM driver
had a bug fix with the accuracy of setting/getting the frequency, and the
duty value is now retained when changing the frequency.
On the samd port there is now support for the internal flash being a block
device, and for filesystems and the os module. Pin and LED classes have
been implemented. There are more time functions, more Python features
enabled, and the help() function is added. SEEED_WIO_TERMINAL and
SEEED_XIAO board definitions are now available.
The stm32 port now has support for F427, F479 and H7A3(Q)/H7B3(Q) MCUs, and
new board definitions for VCC_GND_H743VI, OLIMEX_H407, MIKROE_QUAIL,
GARATRONIC_PYBSTICK26_F411, STM32H73B3I_DK. A bug was fixed in the SPI
driver where a SPI transfer could fail if the CYW43 WiFi driver was also
active at the same time.
On the windows port the help() function has been enabled, and support for
build variants added, to match the unix port.
The zephyr port upgraded Zephyr to v2.7.0.
The change in code size since the previous release for various ports is
(absolute and percentage change in the text section):
bare-arm: -1520 -2.605%
minimal x86: -2256 -1.531%
unix x64: -457 -0.089%
unix nanbox: -925 -0.204%
stm32: +312 +0.079% PYBV10
cc3200: -176 -0.096%
esp8266: +532 +0.076% GENERIC
esp32: +27096 +1.820% GENERIC
nrf: -212 -0.121% pca10040
rp2: +9904 +2.051% PICO
samd: +35332 +33.969% ADAFRUIT_ITSYBITSY_M4_EXPRESS
The changes that dominate these numbers are:
- bare-arm, minimal: use of new MICROPY_CONFIG_ROM_LEVEL_MINIMUM option and
subsequent disabling of remaining optional features
- unix, cc3200, nrf: general code size reductions of the core
- stm32: performance improvements, addition of platform module
- esp8266: enabling f-strings
- esp32: use of -O2 instead of -Os
- rp2: machine.I2S and other new hardware features
- samd: filesystem support and other new hardware features

Some devices, eg BNO055, can stretch SCL for a long time, so make the
default large to accommodate them. 50ms matches the current default for
stm32 hardware I2C .

This targets the 64-bit CPU Raspberry Pis. The BCM2711 on the Pi 4
and the BCM2837 on the Pi 3 and Zero 2W. There are 64-bit fixes
outside of the ports directory for it.
There are a couple other cleanups that were incidental:
* Use const mcu_pin_obj_t instead of omitting the const. The structs
themselves are const because they are in ROM.
* Use PTR <-> OBJ conversions in more places. They were found when
mp_obj_t was set to an integer type rather than pointer.
* Optimize submodule checkout because the Pi submodules are heavy
and unnecessary for the vast majority of builds.
Fixes#4314
Don't force the 'HAL' string to be part of the platform string because
it doesn't have a sensible meaning for all possible platforms, and
swap it with the PLATFORM_ARCH string so the strings which most platforms
have come first.
We're using the MicroPython fork of NimBLE, which on the
`micropython_1_4_0` branch re-adds support for 64-bit targets and fixes
initialisation of g_msys_pool_list.
Also updates modbluetooth_nimble.c to suit v1.4.
