Kevin Köck aca19c25d2 extmod/uasyncio: Add error message to Lock.release's RuntimeError.
Otherwise it can be hard to understand what the error is if a blank
RuntimeError is raised.

Damien George b389bc0afa extmod/uasyncio: Implement Loop.stop() to stop the event loop. 2020-04-02 00:14:18 +11:00
Damien George 711dd392d3 extmod/uasyncio: Don't create a Loop instance in get_event_loop().
The event loop is (for now) just a singleton so make it so that Loop
instances are not needed.

David Lechner a2110bd3fc all: Fix implicit casts of float/double, and signed comparison.
These were found by buiding the unix coverage variant on macOS (so clang
compiler).  Mostly, these are fixing implicit cast of float/double to
mp_float_t which is one of those two and one mp_int_t to size_t fix for
good measure.

David Lechner 9418611c8a unix: Implement PEP 475 to retry syscalls failing with EINTR.
https://www.python.org/dev/peps/pep-0475/

This implements something similar to PEP 475 on the unix port, and for the
VfsPosix class.

There are a few differences from the CPython implementation:
- Since we call mp_handle_pending() between any ENITR's, additional
  functions could be called if MICROPY_ENABLE_SCHEDULER is enabled, not
  just signal handlers.
- CPython only handles signal on the main thread, so other threads will
  raise InterruptedError instead of retrying.  On MicroPython,
  mp_handle_pending() will currently raise exceptions on any thread.

A new macro MP_HAL_RETRY_SYSCALL is introduced to reduce duplicated code
and ensure that all instances behave the same.  This will also allow other
ports that use POSIX-like system calls (and use, eg, VfsPosix) to provide
their own implementation if needed.

Damien George 3b68f36175 extmod/uasyncio: Add manifest.py for freezing uasyncio Py files. 2020-03-26 01:25:45 +11:00
Damien George bc009fdd62 extmod/uasyncio: Add optional implementation of core uasyncio in C.
Implements Task and TaskQueue classes in C, using a pairing-heap data
structure.  Using this reduces RAM use of each Task, and improves overall
performance of the uasyncio scheduler.

Damien George 63b9944382 extmod/uasyncio: Add new implementation of uasyncio module.
This commit adds a completely new implementation of the uasyncio module.
The aim of this version (compared to the original one in micropython-lib)
is to be more compatible with CPython's asyncio module, so that one can
more easily write code that runs under both MicroPython and CPython (and
reuse CPython asyncio libraries, follow CPython asyncio tutorials, etc).
Async code is not easy to write and any knowledge users already have from
CPython asyncio should transfer to uasyncio without effort, and vice versa.

The implementation here attempts to provide good compatibility with
CPython's asyncio while still being "micro" enough to run where MicroPython
runs. This follows the general philosophy of MicroPython itself, to make it
feel like Python.

The main change is to use a Task object for each coroutine.  This allows
more flexibility to queue tasks in various places, eg the main run loop,
tasks waiting on events, locks or other tasks.  It no longer requires
pre-allocating a fixed queue size for the main run loop.

A pairing heap is used to queue Tasks.

It's currently implemented in pure Python, separated into components with
lazy importing for optional components.  In the future parts of this
implementation can be moved to C to improve speed and reduce memory usage.
But the aim is to maintain a pure-Python version as a reference version.

David Lechner 58d9a4815d extmod/vfs_posix_file: Include unistd.h to get STD{IN,OUT,ERR}_FILENO. 2020-03-25 00:59:39 +11:00
Damien George 2cdf1d25f5 unix: Remove custom file implementation to use extmod's VFS POSIX one.
The implementation in extmod/vfs_posix_file.c is now equivalent to that in
ports/unix/file.c, so remove the latter and use the former instead.
2020-03-18 21:01:07 +11:00
Damien George 68b1bc2042 extmod/vfs_posix_file: Lock GIL when writing and allow stdio flush.
Also support MP_STREAM_GET_FILENO ioctl.  The stdio flush change was done
previously for the unix port in 3e0b46b9af.
These changes make this POSIX file implementation equivalent to the unix
file implementation.

Damien George 8f0778b209 extmod/modlwip: Properly handle non-blocking and timeout on UDP recv.
Fixes UDP non-blocking recv so it returns EAGAIN instead of ETIMEDOUT.
Timeout waiting for incoming data is also improved by replacing 100ms delay
with poll_sockets(), as is done in other parts of this module.

Fixes issue #5759.

Damien George 00267aae0b extmod/modlwip: Fix polling of UDP socket so it doesn't return HUP.
STATE_NEW will return HUP when polled so put active UDP sockets into a new
state which is different to STATE_NEW.

Fixes issue #5758.

Damien George dd0bc26e65 extmod/modbluetooth: Change scan result's "connectable" to "adv_type".
This commit changes the BLE _IRQ_SCAN_RESULT data from:

    addr_type, addr, connectable, rssi, adv_data

to:

    addr_type, addr, adv_type, rssi, adv_data

This allows _IRQ_SCAN_RESULT to handle all scan result types (not just
connectable and non-connectable passive scans), and to distinguish between
them using adv_type which is an integer taking values 0x00-0x04 per the BT
specification.

This is a breaking change to the API, albeit a very minor one: the existing
connectable value was a boolean and True now becomes 0x00, False becomes
0x02.

Documentation is updated and a test added.

Fixes #5738.

Thomas Friebel 41a9f1dec8 extmod/modbluetooth: Unify error handling in remaining places.
Most error handling is done via `bluetooth_handle_errno()` already.

Jim Mussared 1937fb22ab extmod/nimble: Clarify active state and check for active in all methods.
This commit ensures that the BLE stack is active before allowing operations
that may otherwise crash if it's not active.  It also clarifies the state
better (adding the "stopping" state) and renames mp_bluetooth_is_enabled to
the more self-explanatory mp_bluetooth_is_active.

Damien George c44d52f33e extmod/modbluetooth_nimble: Move nimble specific code, factor nimble.mk.
Move extmod/modbluetooth_nimble.* to extmod/nimble.  And move common
Makefile lines to extmod/nimble/nimble.mk (which was previously only used
by stm32).  This allows (upcoming) btstack to follow a similar structure.

Damien George ad7213d3c3 py: Add mp_raise_msg_varg helper and use it where appropriate.
This commit adds mp_raise_msg_varg(type, fmt, ...) as a helper for
nlr_raise(mp_obj_new_exception_msg_varg(type, fmt, ...)).  It makes the
C-level API for raising exceptions more consistent, and reduces code size
on most ports:

   bare-arm:   +28 +0.042%
minimal x86:  +100 +0.067%
   unix x64:   -56 -0.011%
unix nanbox:  -300 -0.068%
      stm32:  -204 -0.054% PYBV10
     cc3200:    +0 +0.000%
    esp8266:   -64 -0.010% GENERIC
      esp32:  -104 -0.007% GENERIC
        nrf:  -136 -0.094% pca10040

Damien George 97eca38c4f py: Add mp_raise_type helper macro and use it where appropriate.
This provides a more consistent C-level API to raise exceptions, ie moving
away from nlr_raise towards mp_raise_XXX.  It also reduces code size by a
small amount on some ports.

Damien George bfbd94401d py: Make mp_obj_get_type() return a const ptr to mp_obj_type_t.
Most types are in rodata/ROM, and mp_obj_base_t.type is a constant pointer,
so enforce this const-ness throughout the code base.  If a type ever needs
to be modified (eg a user type) then a simple cast can be used.

Damien George d97b40bdaa py: Introduce MP_ROM_FALSE/MP_ROM_TRUE for ROM to refer to bool objects.
This helps to prevent mistakes, and allows easily changing the ROM value of
False/True if needed.

Damien George ed2be79b49 extmod/uzlib: Explicitly cast ptr-diff-expr to unsigned.
The struct member "dest" should never be less than "destStart", so their
difference is never negative.  Cast as such to make the comparison
explicitly unsigned, ensuring the compiler produces the correct comparison
instruction, and avoiding any compiler warnings.

Jim Mussared 7ce1e0b1dc extmod/webrepl: Move webrepl scripts to common place and use manifest.
Move webrepl support code from ports/esp8266/modules into extmod/webrepl
(to be alongside extmod/modwebrepl.c), and use frozen manifests to include
it in the build on esp8266 and esp32.

A small modification is made to webrepl.py to make it work on non-ESP
ports, i.e. don't call dupterm_notify if not available.

Damien George 84958a8fe1 extmod/modbluetooth: Allow setting ringbuf size via BLE.config(rxbuf=).
The size of the event ringbuf was previously fixed to compile-time config
value, but it's necessary to sometimes increase this for applications that
have large characteristic buffers to read, or many events at once.

With this commit the size can be set via BLE.config(rxbuf=512), for
example.  This also resizes the internal event data buffer which sets the
maximum size of incoming data passed to the event handler.
