Jim Mussared 4ab5156c01 tools/mpy-tool.py: Force native func alignment to halfword/word on ARM.
This is necessary for ARMV6 and V7.  Without this change, calling a frozen
native/viper function that is misaligned will crash.

Milan Rossa ae6fe8b43c py/compile: Improve the line numbering precision for comprehensions.
The line number for comprehensions is now always reported as the correct
global location in the script, instead of just "line 1".

Damien George 7d851a27f1 extmod/modure: Make regex dump-code debugging feature optional.
Enabled via MICROPY_PY_URE_DEBUG, disabled by default (but enabled on unix
coverage build).  This is a rarely used feature that costs a lot of code
(500-800 bytes flash).  Debugging of regular expressions can be done
offline with other tools.

Damien George 11ecdf2ec6 py/nlr: Use MP_UNREACHABLE at the end of arch-specific nlr_jump funcs.
Recent versions of gcc perform optimisations which can lead to the
following code from the MP_NLR_JUMP_HEAD macro being omitted:

    top->ret_val = val; \
    MP_NLR_RESTORE_PYSTACK(top); \
    *_top_ptr = top->prev; \

This is noticeable (at least) in the unix coverage on x86-64 built with gcc
9.1.0.  This is because the nlr_jump function is marked as no-return, so
gcc deduces that the above code has no effect.

Adding MP_UNREACHABLE tells the compiler that the asm code may branch
elsewhere, and so it cannot optimise away the code.

Damien George 0c80cb39af py: Introduce MP_UNREACHABLE macro to annotate unreachable code.
And use it to replace the same pattern at the end of nlrthumb.c:nlr_jump.

stijn af5c998f37 py/modmath: Implement math.isclose() for non-complex numbers.
As per PEP 485, this function appeared in for Python 3.5.  Configured via
MICROPY_PY_MATH_ISCLOSE which is disabled by default, but enabled for the
ports which already have MICROPY_PY_MATH_SPECIAL_FUNCTIONS enabled.

Damien George 3eff81288c stm32/i2c: Fix generation of restart condition for hw I2C on F0/F7.
Before this patch I2C transactions using a hardware I2C peripheral on F0/F7
MCUs would not correctly generate the I2C restart condition, and instead
would generate a stop followed by a start.  This is because the CR2 AUTOEND
bit was being set before CR2 START when the peripheral already had the I2C
bus from a previous transaction that did not generate a stop.

As a consequence all combined transactions, eg read-then-write for an I2C
memory transfer, generated a stop condition after the first transaction and
didn't generate a stop at the very end (but still released the bus).  Some
I2C devices require a repeated start to function correctly.

This patch fixes this by making sure the CR2 AUTOEND bit is set after the
start condition and slave address have been fully transferred out.

mpconfigboard.h.

Jim Mussared 8db517f26d esp32: Add per-board configs, following other ports.
Replaces the `SDKCONFIG` makefile variable with `BOARD`.  Defaults to
BOARD=GENERIC.  spiram can be enabled with `BOARD=GENERIC_SPIRAM`

Add example definition for TINYPICO, currently identical to GENERIC_SPIRAM
but with custom board/SoC names for the uPy banner.

Damien George acfbb9febd py/objarray: Fix amount of free space in array when doing slice assign.
Prior to this patch the amount of free space in an array (including
bytearray) was not being maintained correctly for the case of slice
assignment which changed the size of the array.  Under certain cases (as
encoded in the new test) it was possible that the array could grow beyond
its allocated memory block and corrupt the heap.

Fixes issue #4127.

Vicki Lowe afd10a4531 docs/pyboard: Emphasize the instructions for making a USB mouse.
It wasn't clear why that element was `10` instead of `0`.  Also bumped the

Milan Rossa 6f0c6bd774 unix: Enable sys.atexit, triggered after the main script ends. 2019-08-15 17:31:04 +10:00
Milan Rossa cb3647004f py: Implement new sys.atexit feature.
This patch implements a new sys.atexit function which registers a function
that is later executed when the main script ends.  It is configurable via
MICROPY_PY_SYS_ATEXIT, disabled by default.

This is not compliant with CPython, rather it can be used to implement a
CPython compatible "atexit" module if desired (similar to how
sys.print_exception can be used to implement functionality of the
"traceback" module).

Damien George 2ccf030fd1 esp32: Add support for mDNS queries and responder.
They are both enabled by default, but can be disabled by defining
MICROPY_HW_ENABLE_MDNS_QUERIES and/or MICROPY_HW_ENABLE_MDNS_RESPONDER to
0.  The hostname for the responder is currently taken from
tcpip_adapter_get_hostname() but should eventually be configurable.

Kenta IDA b6906fa573 esp32/network_ppp: Add authentication support to the PPP interface.
This commit adds the connect() method to the PPP interface and requires
that connect() be called after active(1).  This is a breaking change for
the PPP API.

With the connect() method it's now possible to pass in authentication
information for PAP/CHAP, eg:

    ppp.active(1)
    ppp.connect(authmode=ppp.AUTH_PAP, username="user", "password="password")

If no authentication is needed simply call connect() without any
parameters.  This will get the original behaviour of calling active(1).

Chris Wilson 3d02ebb4e8 stm32/sdcard: Support configuring the SD/MMC bus width to 1 or 4 bits.
Some SD/MMC breakout boards don't support 4-bit bus mode.  This adds a new
macro MICROPY_HW_SDMMC_BUS_WIDTH that allows each board to define the width
of the SD/MMC bus interface used on that board, defaulting to 4 bits.

Paul m. p. P f60229e261 py/modio: Call mp_import_name to do resource stream import.
So code is not duplicated and it can take advantage of __import__ being
overridden.

Paul m. p. P 60f1063797 py/runtime: Allow to override builtins.__import__ with Python func.
This patch adds a simple but powerful hook into the import system, in a
CPython compatible way, by allowing to override builtins.__import__.

This does introduce some overhead to all imports but it's minor:
- the dict lookup of __import__ is bypassed if there are no modifications
  to the builtins module (which is the case at start up);
- imports are not performance critical, usually done just at the start of a
  script;
- compared to how much work is done in an import, looking up a value in a
  dict is a relatively small additional piece of work.

Paul m. p. P a8e3201b37 py/builtinimport: Populate __file__ when importing frozen or mpy files.
Note that bytecode already includes the source filename as a qstr so there
is no additional memory used by the interning operation here.

Eric Poulsen 01054f2092 py/objdict: Quote non-string types when used as keys in JSON output.
JSON requires that keys of objects be strings.  CPython will therefore
automatically quote simple types (NoneType, bool, int, float) when they are
used directly as keys in JSON output.  To prevent subtle bugs and emit
compliant JSON, MicroPython should at least test for such keys so they
aren't silently let through.  Then doing the actual quoting is a similar
cost to raising an exception, so that's what is implemented by this patch.

Fixes issue #4790.

Damien George fa07deda9f stm32/usbd_hid_interface: Rewrite USB HID interface code.
The previous version did not work on MCUs that only had USB device mode
(compared to OTG) because of the handling of NAK.  And this previous
handling of NAK had a race condition where a new packet could come in
before USBD_HID_SetNAK was called (since USBD_HID_ReceivePacket clears NAK
as part of its operation).  Furthermore, the double buffering of incoming
reports was not working, only one buffer could be used at a time.

This commit rewrites the HID interface code to have a single incoming
buffer, and only calls USBD_HID_ReceivePacket after the user has read the
incoming report (similar to how the VCP does its flow control).  As such,
USBD_HID_SetNAK and USBD_HID_ClearNAK are no longer needed.

API functionality from the user's point of view should be unchanged with
this commit.
