Damien George 6d8816fe84 tests/import: Add test for importing invalid .mpy file. 2018-06-18 17:50:34 +10:00
Damien George 48829cd3c6 tests/extmod: Add test for ujson.dump writing to a user IOBase object. 2018-06-18 12:35:56 +10:00
Damien George 0ecce77c66 tests/extmod/ujson_dump.py: Add test for dump to non-stream object. 2018-06-18 12:35:56 +10:00
Damien George a5f5552a0a tests/unix/extra_coverage: Don't test stream objs with NULL write fun.
This behaviour of a NULL write C method on a stream that uses the write
adaptor objects is no longer supported.  It was only ever used by the
coverage build for testing the fail path of mp_get_stream_raise().

Damien George 6a445b60fa py/lexer: Add support for underscores in numeric literals.
This is a very convenient feature introduced in Python 3.6 by PEP 515.

Damien George a12d046c42 tests/pyb: Make i2c and pyb1 pyboard tests run again.
For i2c.py: the accelerometer now uses the new I2C driver so need to
explicitly init the legacy i2c object to get the test working.

For pyb1.py: the legacy pyb.hid() call will crash if the USB_HID object is
not initialised.

Damien George 36c1052183 py/objtype: Optimise instance get/set/del by skipping special accessors.
This patch is a code optimisation, trading text bytes for speed.  On
pyboard it's an increase of 0.06% in code size for a gain (in pystone
performance) of roughly 6.5%.

The patch optimises load/store/delete of attributes in user defined classes
by not looking up special accessors (@property, __get__, __delete__,
__set__, __setattr__ and __getattr_) if they are guaranteed not to exist in
the class.

Currently, if you do my_obj.foo() then the runtime has to do a few checks
to see if foo is a property or has __get__, and if so delegate the call.
And for stores things like my_obj.foo = 1 has to first check if foo is a
property or has __set__ defined on it.

Doing all those checks each and every time the attribute is accessed has a
performance penalty.  This patch eliminates all those checks for cases when
it's guaranteed that the checks will always fail, ie no attributes are
properties nor have any special accessor methods defined on them.

To make this guarantee it checks all attributes of a user-defined class
when it is first created.  If any of the attributes of the user class are
properties or have special accessors, or any of the base classes of the
user class have them, then it sets a flag in the class to indicate that
special accessors must be checked for.  Then in the load/store/delete code
it checks this flag to see if it can take the shortcut and optimise the
lookup.

It's an optimisation that's pretty widely applicable because it improves
lookup performance for all methods of user defined classes, and stores of
attributes, at least for those that don't have special accessors.  And, it
allows to enable descriptors with minimal additional runtime overhead if
they are not used for a particular user class.

There is one restriction on dynamic class creation that has been introduced
by this patch: a user-defined class cannot go from zero special accessors
to one special accessor (or more) after that class has been subclassed.  If
the script attempts this an AttributeError is raised (see addition to
tests/misc/non_compliant.py for an example of this case).

The cost in code space bytes for the optimisation in this patch is:

   unix x64:  +528
unix nanbox:  +508
      stm32:  +192
     cc3200:  +200
    esp8266:  +332
      esp32:  +244

Performance tests that were done:

- on unix x86-64, pystone improved by about 5%
- on pyboard, pystone improved by about 6.5%, from 1683 up to 1794
- on pyboard, bm_chaos (from CPython benchmark suite) improved by about 5%
- on esp32, pystone improved by about 30% (but there are caching effects)
- on esp32, bm_chaos improved by about 11%

Damien George 5ef0d2ab14 tests/extmod: Remove conditional import of uos_vfs, it no longer exists.
This conditional import was only used to get the tests working on the unix
coverage build, which has now switched to use VFS by default so the uos
module alone has the required functionality.

Damien George 6c02da2eec tests/extmod: Add test for importing a script from a user VFS. 2018-06-06 14:28:23 +10:00
Jeff Epler c60589c02b py/objtype: Fix assertion failures in super_attr by checking type.
Fixes assertion failures and segmentation faults when making calls like:

    super(1, 1).x

Jeff Epler 05b13fd292 py/objtype: Fix assertion failures in mp_obj_new_type by checking types.
Fixes assertion failures when the arguments to type() were not of valid
types, e.g., when making calls like:

    type("", (), 3)
    type("", 3, {})

Damien George dfeaea1441 py/objtype: Remove TODO comment about needing to check for property.
Instance members are always treated as values, even if they are properties.
A test is added to show this is the case.

Damien George 400273a799 py/objgenerator: Protect against reentering a generator.
Generators that are already executing cannot be reexecuted.  This patch
puts in a check for such a case.

Thanks to @jepler for finding the bug.

Jan Klusacek b318ebf101 py/modbuiltins: Add support for rounding integers.
As per CPython semantics.  This feature is controlled by
MICROPY_PY_BUILTINS_ROUND_INT which is disabled by default.

Damien George 1ad0013dec tests: Add some tests for bigint hash, float hash and float parsing.
Following outcome of recent fuzz testing and sanitizing by @jepler.

Damien George 7541be5637 tests/basics/special_methods2: Enable some additional tests that work.
These special methods are all available if MICROPY_PY_ALL_SPECIAL_METHODS
is enabled.

Damien George d2c1db1e5c tests/float/float_parse: Allow test to run on 32-bit archs.
Printing of uPy floats can differ by the floating-point precision on
different architectures (eg 64-bit vs 32-bit x86), so it's not possible to
using printing of floats in some parts of this test.  Instead we can just
check for equivalence with what is known to be the correct answer.
2018-05-11 13:51:18 +10:00
Damien George 3678a6bdc6 py/modbuiltins: Make built-in dir support the __dir__ special method.
If MICROPY_PY_ALL_SPECIAL_METHODS is enabled then dir() will now delegate
to the special method __dir__ if the object it is listing has this method.
2018-05-10 23:14:23 +10:00
Damien George 529860643b py/modbuiltins: Make built-in hasattr work properly for user types.
It now allows __getattr__ in a user type to raise AttributeError when the
attribute does not exist.
2018-05-10 23:03:30 +10:00
Damien George 2ada1124d4 tests/cpydiff: Remove types_int_tobytesfloat now that it doesn't fail.
Commit e269cabe3e added a check that the
first argument to the to_bytes() method is an integer, and now uPy
follows CPython behaviour and raises a TypeError for this test.

Note: CPython checks the argument types before checking the number of
arguments, but uPy does it the other way around, so they give different
exception messages for this test, but still the same type, a TypeError.

Damien George 74ab341d3a tests/cpydiff: Remove working cases from types_float_rounding. 2018-05-04 22:30:50 +10:00
Damien George cd9d71edc8 tests/cpydiff: Remove types_str_decodeerror now that it succeeds.
Commit 68c28174d0 implemented checking for
valid utf-8 data.
2018-05-04 22:27:14 +10:00
Damien George 4b5111f8e1 tests/cpydiff: Remove core_function_unpacking now that it succeeds.
Commit 1e70fda69f fixes this difference.

Ayke van Laethem 5eb198c441 tests/run-tests: Support esp32 as a target for running the test suite. 2018-05-02 17:20:48 +10:00
Damien George db2bdad8a2 tests/pyb: Update tests to run correctly on PYBv1.0.
In adcall.py the pyb module may not be imported, so use ADCAll directly.

In dac.py the DAC object now prints more info, so update .exp file.

In spi.py the SPI should be deinitialised upon exit, so the test can run a
second time correctly.

Mike Wadsten 9f1eafc380 tests/io/bytesio_ext2: Remove dependency on specific EINVAL value
If MICROPY_USE_INTERNAL_ERRNO is disabled, MP_EINVAL is not guaranteed
to have the value 22, so we cannot depend on OSError(22,).
Instead, to support any given port's errno values, without relying
on uerrno, we just check that the args[0] is positive.
2018-05-01 15:48:43 +10:00
Damien George d12483d936 tests/pyb: Add test for pyb.ADCAll class. 2018-04-11 17:12:13 +10:00
Damien George b30e0d2f26 stm32/dac: Add buffering argument to constructor and init() method.
This can be used to select the output buffer behaviour of the DAC.  The
default values are chosen to retain backwards compatibility with existing
behaviour.

Thanks to @peterhinch for the initial idea to add this feature.

Peter Hinch 4f40fa5cf4 stm32/adc: Add read_timed_multi() static method, with docs and tests. 2018-04-11 13:36:17 +10:00
Damien George 0096a4bd00 tests/pyb/adc.py: Fix test so that it really does test ADC values.
Reading into a bytearray will truncate values to 0xff so the assertions
checking read_timed() would previously always succeed.

Thanks to @peterhinch for finding this problem and providing the solution.
2018-04-11 13:21:57 +10:00
Damien George 5ad27d4b8b tests: Move recursive tests to the tests/stress/ subdir.
Keeping all the stress related tests in one place makes it easier to
stress-test a given port, and to also not run such tests on ports that
can't handle them.
2018-04-10 14:43:52 +10:00
Damien George 605fdcf754 tests/stress/recursive_gen: Add test for recursive gen with iter. 2018-04-10 14:39:51 +10:00
Jeff Epler cbf981f330 py/objgenerator: Check stack before resuming a generator.
This turns a hard crash in a recursive generator into a 'maximum recursion
depth exceeded' exception.

Damien George 5995a199a3 tests/micropython: Add set of tests for extreme cases of raising exc's. 2018-04-05 01:06:40 +10:00
Damien George 1bfc774a08 tests/basics/string_compare.py: Add test with string that hashes to 0.
The string "Q+?" is special in that it hashes to zero with the djb2
algorithm (among other strings), and a zero hash should be incremented to a
hash of 1.
2018-04-05 01:04:38 +10:00
Damien George 22161acf47 tests/basics/class_super.py: Add tests for store/delete of super attr. 2018-04-05 01:03:57 +10:00

Damien George a45a34ec31 tests/stress: Add test to verify the GC can trace nested objects. 2018-04-04 14:22:54 +10:00
Damien George 7d5c753b17 tests/basics: Modify int-big tests to prevent constant folding.
So that these tests test the runtime behaviour, not the compiler (which may
be executed offline).
2018-04-04 13:57:22 +10:00
Damien George f684e9e1ab tests/basics/int_big1.py: Add test converting str with non-print chars. 2018-04-04 13:56:00 +10:00
Damien George 430efb0444 tests/basics: Add test for use of return within try-except.
The case of a return statement in the try suite of a try-except statement
was previously only tested by builtin_compile.py, and only then in the part
of this test which checked for the existence of the compile builtin.  So
this patch adds an explicit unit test for this case.
