Merge tag 'v1.9' into parse-bytecode
New VFS subsystem and scheduling framework, and less need for the heap
This release adds some fundamental new components, allows for more Python
operations without using the heap and has reduced code size and stack
usage.
Changes in the way iterators are handled allows to iterate without
allocating on the heap for the types: tuple, list, str, bytes, bytearray,
array, dict, set, frozenset. It also allows to call the builtins all, any,
min max and sum without allocating heap memory for the iterator argument.
And improvements to the handling of super() means that super().foo() method
calls are now heap-less.
A new generic VFS subsystem has been added which allows to mount arbitrary
filesystems (even written in Python) at the root or at a mount-point within
the root. The FatFS driver has been replaced with an object-oriented
version (oofatfs) which allows a fully customisable filesystem layout.
A scheduling framework has been implemented in the core which gives the
ability to schedule callbacks to be called "as soon as possible". This
allows ports to implement "soft IRQs" which allow the programmer to
allocate memory during an interrupt handler, at the cost of some
performance related to response time of the handler. The new
micropython.schedule() function gives access to the scheduler.
Other improvements to the core include: consts can now be big-nums, for
example "X = const(1 << 100)"; addition of "help('modules')" to list
available modules; stack usage reduced for a Python call by 8 bytes on ARM
Cortex-M architectures; micropython.kbd_intr() function added to disable
Ctrl-C capture; addition of uio.resource_stream(); mpy-cross is built
automatically if needed; a helper tool mpy_cross_all.py is added to run
mpy-cross on an entire project.
The bytecode has changed in this version so existing .mpy files will need
recompiling. There have also been some changes to the C API, most notably
with mp_uint_t changed to size_t in many places.
In the extended modules the following main changes have been made: addition
of machine.Signal class to allow inversion on a Pin; framebuf has new
formats of the form MONO_xxx; addition of uselect.ipoll() for allocation-
free polling; addition of uos.ilistdir() for efficient iteration of a
directory listing; machine.Pin high/low methods are renamed to on/off in
esp8266 and zephyr (this is a backwards-incompatible change);
machine.time_pulse_us() function no longer throws exceptions, but returns
negative values instead.
For stmhal the pyb.fault_debug() function is added, and default behaviour
for a hard-fault is now an immediate reset. There is better support for F7
MCUs, in particular DMA and SD card support. A bug has been fixed with the
USB VCP (USB serial) where it would in rare cases (usually when the host PC
was under load) would lose characters. Pyboard now automatically mounts
all available partitions on the SD card. Multithreading has been
implemented and is available via the _thread module, but this feature is
disabled by default and must be enabled at compile time using the
MICROPY_THREAD and MICROPY_THREAD_GIL options. The ability to skip booting
from SD card is now available by creating an empty file on the flash called
"SKIPSD".
The cc3200 port has had some backwards incompatible changes, in particular
with I2C, Pin, UART and uos. Please see the documentation for the new
behaviour.
The esp8266 port has had a change in the size of the firmware in order to
accommodate additional features. As such the filesystem for this version
is incompatible with v1.8.7 and a device requires backup and erasure before
flashing this version. Soft IRQs are now implemented for Pin and Timer
callbacks, along with the general improvements described above.
In the documentation there is now a section describing the differences
between MicroPython and CPython. And code coverage is up to 98% across py/
and extmod/.
Changes in code size (in bytes) between v1.8.7 and this version are:
bare-arm: -1104
minimal: -1324
unix x64: -1115
unix nanbox: -11106
stmhal: +18116
cc3200: +1032
esp8266: +3060
Note that stmhal has increased significantly due to the addition of frozen
bytecode and the LCD160CR driver.
