2020-04-05extmod/modubinascii: Make code private and module self-contained.Jim Mussared
This commit makes all functions and function wrappers in modubinascii.c STATIC and conditional on the MICROPY_PY_UBINASCII setting, which will exclude the file from qstr/ compressed-string searching when ubinascii is not enabled. The now-unused modubinascii.h header file is also removed. The cc3200 port is updated accordingly to use this module in its entirety instead of providing its own top-level definition of ubinascii. This was originally like this because the cc3200 port has its own ubinascii module which referenced these methods. The plan appeared to be that the API might diverge (e.g. hardware crc), but this should be done similar to I2C/SPI via a port-specific handler, rather than the port having its own definition of the module. Having a centralised module definition also enforces consistency of the API among ports.
2020-04-04extmod/uasyncio: Add global exception handling methods.Kevin Köck
This commit adds support for global exception handling in uasyncio according to the CPython error handling: https://docs.python.org/3/library/asyncio-eventloop.html#error-handling-api This allows a program to receive exceptions from detached tasks and log them to an appropriate location, instead of them being printed to the REPL. The implementation preallocates a context dictionary so in case of an exception there shouldn't be any RAM allocation. The approach here is compatible with CPython except that in CPython the exception handler is called once the task that threw an uncaught exception is freed, whereas in MicroPython the exception handler is called immediately when the exception is thrown.
2020-04-02extmod/uasyncio: Add StreamReader/StreamWriter as aliases of Stream cls.Damien George
To be compatible with CPython. Fixes issue #5847.
2020-04-02extmod/uasyncio: Add error message to Lock.release's RuntimeError.Kevin Köck
Otherwise it can be hard to understand what the error is if a blank RuntimeError is raised.
2020-04-02extmod/uasyncio: Implement Loop.stop() to stop the event loop.Damien George
2020-04-01extmod/uasyncio: Don't create a Loop instance in get_event_loop().Damien George
The event loop is (for now) just a singleton so make it so that Loop instances are not needed.
2020-03-30all: Fix implicit casts of float/double, and signed comparison.David Lechner
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.
2020-03-28all: Remove spaces inside and around parenthesis.Damien George
Using new options enabled in the uncrustify configuration.
2020-03-27unix: Implement PEP 475 to retry syscalls failing with EINTR.David Lechner
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.
2020-03-26extmod/uasyncio: Add manifest.py for freezing uasyncio Py files.Damien George
2020-03-26extmod/uasyncio: Add optional implementation of core uasyncio in C.Damien George
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.
2020-03-26extmod/uasyncio: Add new implementation of uasyncio module.Damien George
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.
2020-03-25extmod/vfs_posix_file: Include unistd.h to get STD{IN,OUT,ERR}_FILENO.David Lechner
2020-03-18unix: Remove custom file implementation to use extmod's VFS POSIX one.Damien George
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.
2020-03-18extmod/vfs_posix_file: Lock GIL when writing and allow stdio flush.Damien George
Also support MP_STREAM_GET_FILENO ioctl. The stdio flush change was done previously for the unix port in 3e0b46b9af8b7a6934b7ac68671ef8f55be2b848. These changes make this POSIX file implementation equivalent to the unix file implementation.
2020-03-18all: Convert exceptions to use mp_raise_XXX helpers in remaining places.Damien George
2020-03-18extmod/modlwip: Properly handle non-blocking and timeout on UDP recv.Damien George
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.
2020-03-18extmod/modlwip: Fix polling of UDP socket so it doesn't return HUP.Damien George
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.
2020-03-11extmod/vfs: Factor out vfs mount-and-chdir helper from stm32.Damien George
2020-03-11extmod/nimble: When getting BLE MAC try public address if random fails.Damien George
This is needed for BLE.config('mac') to work on esp32.
2020-03-11extmod/modbluetooth: Change scan result's "connectable" to "adv_type".Damien George
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.
2020-03-11extmod/modbluetooth: Unify error handling in remaining places.Thomas Friebel
Most error handling is done via `bluetooth_handle_errno()` already. Replace the remaining few manual checks with calls to that function.
2020-03-11extmod/nimble: Clarify active state and check for active in all methods.Jim Mussared
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.
2020-03-10stm32: Refactor Bluetooth HCI RX to be independent of transport layer.Damien George
Now all HCI specific code (eg UART vs WB55 internal messaging) is confined to modbluetooth_hci.c.

2020-03-10stm32: Refactor bluetooth stack/hci/driver bindings.Damien George
This makes a cleaner separation between the: driver, HCI UART and BT stack. Also updated the naming to be more consistent (mp_bluetooth_hci_*). Work done in collaboration with Jim Mussared aka @jimmo.
2020-03-06extmod/modbluetooth_nimble: Move nimble specific code, factor nimble.mk.Damien George
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. Work done in collaboration with Jim Mussared aka @jimmo.
2020-02-28all: Reformat C and Python source code with tools/codeformat.py.Damien George
This is run with uncrustify 0.70.1, and black 19.10b0.

2020-02-18py: Factor out definition of mp_float_union_t to one location.Damien George
2020-02-13py: Add mp_raise_msg_varg helper and use it where appropriate.Damien George
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 samd: +0 +0.000% ADAFRUIT_ITSYBITSY_M4_EXPRESS
2020-02-13py: Add mp_raise_type helper macro and use it where appropriate.Damien George
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.
2020-01-26extmod/vfs_posix: Release GIL during system calls.David Lechner
This releases the GIL during syscalls that could block.
2020-01-09py: Make mp_obj_get_type() return a const ptr to mp_obj_type_t.Damien George
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.
2019-12-27extmod/modbluetooth: Fix func prototype, empty args should be (void).Yonatan Goldschmidt
This fixes a -Wstrict-prototypes error.
2019-12-27extmod: Fix modbluetooth and modwebrepl to build in nanbox mode.Damien George
2019-12-27py: Introduce MP_ROM_FALSE/MP_ROM_TRUE for ROM to refer to bool objects.Damien George
This helps to prevent mistakes, and allows easily changing the ROM value of False/True if needed.
2019-12-27py: Introduce MP_ROM_NONE macro for ROM to refer to None object.Damien George
This helps to prevent mistakes, and allows easily changing the ROM value of None if needed.
2019-12-23extmod/uzlib: Explicitly cast ptr-diff-expr to unsigned.Damien George
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.
2019-12-20extmod/webrepl: Move webrepl scripts to common place and use manifest.Jim Mussared
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.
2019-12-13examples/natmod: Add urandom native module example.Damien George
