This commit adds micropython.heap_locked() which returns the current
lock-depth of the heap, and can be used by Python code to check if the heap
is locked or not. This new function is configured via
MICROPY_PY_MICROPYTHON_HEAP_LOCKED and is disabled by default.
This commit also changes the return value of micropython.heap_unlock() so
it returns the current lock-depth as well.
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.
This commit adds a test runner and initial test scripts which run multiple
Python/MicroPython instances (eg executables, target boards) in parallel.
This is useful for testing, eg, network and Bluetooth functionality.
Each test file has a set of functions called instanceX(), where X ranges
from 0 up to the maximum number of instances that are needed, N-1. Then
run-multitests.py will execute this script on N separate instances (eg
micropython executables, or attached boards via pyboard.py) at the same
time, synchronising their start in the right order, possibly passing IP
address (or other address like bluetooth MAC) from the "server" instance to
the "client" instances so they can connect to each other. It then runs
them to completion, collects the output, and then tests against what
CPython gives (or what's in a provided .py.exp file).
The tests will be run using the standard unix executable for all instances
by default, eg:
$ ./run-multitests.py multi_net/*.py
Or they can be run with a board and unix executable via:
$ ./run-multitests.py --instance pyb:/dev/ttyACM0 --instance exec:micropython multi_net/*.py
Only the "==" operator was tested by the test suite in for such arguments.
Other comparison operators like "<" take a different path in the code so
need to be tested separately.
When this variable is set to non-empty string it triggers the REPL after a
command/module/file finishes running.
The Python file without the file extension is because the cmdline: parser
in run-test splits on spaces, so we can't use the -c option since
`import os` can't be written without a space.
This commit implements a more complete replication of CPython's behaviour
for equality and inequality testing of objects. This addresses the issues
discussed in #5382 and a few other inconsistencies. Improvements over the
old code include:
- Support for returning non-boolean results from comparisons (as used by
numpy and others).
- Support for non-reflexive equality tests.
- Preferential use of __ne__ methods and MP_BINARY_OP_NOT_EQUAL binary
operators for inequality tests, when available.
- Fallback to op2 == op1 or op2 != op1 when op1 does not implement the
(in)equality operators.
The scheme here makes use of a new flag, MP_TYPE_FLAG_NEEDS_FULL_EQ_TEST,
in the flags word of mp_obj_type_t to indicate if various shortcuts can or
cannot be used when performing equality and inequality tests. Currently
four built-in classes have the flag set: float and complex are
non-reflexive (since nan != nan) while bytearray and frozenszet instances
can equal other builtin class instances (bytes and set respectively). The
flag is also set for any new class defined by the user.
This commit also includes a more comprehensive set of tests for the
behaviour of (in)equality operators implemented in special methods.
This commit adds a generator test for throwing into a nested exception, and
one when using yield-from with a pending exception cleanup. Both these
tests currently fail on the native emitter, and are simplified versions of
native test failures from uasyncio in #5332.
This commit adds backward-word, backward-kill-word, forward-word,
forward-kill-word sequences for the REPL, with bindings to Alt+F, Alt+B,
Alt+D and Alt+Backspace respectively. It is disabled by default and can be
enabled via MICROPY_REPL_EMACS_WORDS_MOVE.
Further enabling MICROPY_REPL_EMACS_EXTRA_WORDS_MOVE adds extra bindings
for these new sequences: Ctrl+Right, Ctrl+Left and Ctrl+W.
The features are enabled on unix micropython-coverage and micropython-dev.
As the mktime documentation for CPython states: "The earliest date for
which it can generate a time is platform-dependent". In particular on
Windows this depends on the timezone so e.g. for UTC+2 the earliest is 2
hours past midnight January 1970. So change the reference to the earliest
possible, for UTC+14.
It is possile for `run_feature_check(pyb, args, base_path, 'float.py')` to
return `b'CRASH'`. This causes an unhandled exception in `int()`.
This commit fixes the problem by first testing for `b'CRASH'` before trying
to convert the return value to an integer.
Instances of the slice class are passed to __getitem__() on objects when
the user indexes them with a slice. In practice the majority of the time
(other than passing it on untouched) is to work out what the slice means in
the context of an array dimension of a particular length. Since Python 2.3
there has been a method on the slice class, indices(), that takes a
dimension length and returns the real start, stop and step, accounting for
missing or negative values in the slice spec. This commit implements such
a indices() method on the slice class.
It is configurable at compile-time via MICROPY_PY_BUILTINS_SLICE_INDICES,
disabled by default, enabled on unix, stm32 and esp32 ports.
This commit also adds new tests for slice indices and for slicing unicode
strings.
Allows assigning attributes on class instances that implement their own
__setattr__. Both object.__setattr__ and super(A, b).__setattr__ will work
with this commit.
Because CPython 3.8.0 now produces different output:
- basics/parser.py: CPython does not allow '\\\n' as input.
- import/import_override: CPython imports _io.
