Arsenijs 00e7fe8ab1 docs/library/framebuf: Add missing module reference in example code. 2019-07-31 23:45:24 +10:00
Damien George 48f43b77aa tests: Add tests for overriding builtins.__import__. 2019-07-31 22:37:44 +10:00
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.

Damien George 7c15e50eb8 esp32/Makefile: Include CFLAGS_EXTRA in CFLAGS definition.
Following other ports, so builds can be customised more easily, eg on the
command line building with a user C-module.

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.

Damien George b1129df478 stm32/dma: Fix re-start of DMA stream by clearing all event flags.

Damien George 4d94fae833 tools/pyboard.py: Add filesystem commands to ls/cat/cp/rm remote files.
Use "-f" to select filesystem mode, followed by the command to execute.
Optionally put ":" at the start of a filename to indicate that it's on the
remote device, if it would otherwise be ambiguous.

Examples:

    $ pyboard.py -f ls
    $ pyboard.py -f cat main.py
    $ pyboard.py -f cp :main.py .   # get from device
    $ pyboard.py -f cp main.py :    # put to device
    $ pyboard.py -f rm main.py

Amir Gonnen 995f9cfdfc esp32: Pin MicroPython tasks to a specific core.
On this port the GIL is enabled and everything works under the assumption
of the GIL, ie that a given task has exclusive access to the uPy state, and
any ISRs interrupt the current task and therefore the ISR inherits
exclusive access to the uPy state for the duration of its execution.

If the MicroPython tasks are not pinned to a specific core then an ISR may
be executed on a different core to the task, making it possible for the
main task and an ISR to execute in parallel, breaking the assumption of the
GIL.

The easiest and safest fix for this is to pin all MicroPython related code
to the same CPU core, as done by this patch.  Then any ISR that accesses
MicroPython state must be registered from a MicroPython task, to ensure it
is invoked on the same core.

See issue #4895.

stijn 9da46a98cb windows/mpconfigport.h: Don't define restrict/inline/alignof for C++.
The C++ standard forbids redefining keywords, like inline and alignof, so
guard these definitions to avoid that, allowing to include the MicroPython
headers by C++ code.

Damien George 59b7166d87 stm32: Add initial support for STM32WBxx MCUs.
This new series of MCUs is similar to the L4 series with an additional
Cortex-M0 coprocessor.  The firmware for the wireless stack must be managed
separately and MicroPython does not currently interface to it.  Supported
features so far include: RTC, UART, USB, internal flash filesystem.

__builtin___clear_cache which is available under both gcc and clang.

Also replace tabs with spaces in this section of code (introduced by a
previous commit).

Damien George fd49fcb229 stm32/gccollect: Always use MP_STATE_THREAD(stack_top) to get stack top.
In a non-thread build, using &_ram_end as the top-of-stack is no longer
correct because the stack is not always at the very top end of RAM.  See
eg 04c7cdb668 and
3786592097.  The correct value to use is
&_estack, which is the value stored in MP_STATE_THREAD(stack_top), and
using the same code for both thread and non-thread builds makes the code
cleaner.
