Ayke van Laethem 6572029dc0 tests: Make tests work on targets without float support. 2018-08-04 15:14:23 +10:00
Damien George 571295d090 tests/extmod/ujson_dump_iobase.py: Return number of bytes written.
Otherwise returning None indicates that the write would block and nothing
was actually written.  Fixes issue #3990.

Damien George e2e22e3d7e py/objgenerator: Implement __name__ with normal fun attr accessor code.
With the recent change b488a4a848, a
generating function now has the same layout in memory as a normal bytecode
function, and so can reuse the latter's attribute accessor code to
implement __name__.

Damien George d8dc918deb py/compile: Handle return/break/continue correctly in async with.
Before this patch the context manager's __aexit__() method would not be
executed if a return/break/continue statement was used to exit an async
with block.  async with now has the same semantics as normal with.

The fix here applies purely to the compiler, and does not modify the
runtime at all. It might (eventually) be better to define new bytecode(s)
to handle async with (and maybe other async constructs) in a cleaner, more
efficient way.

One minor drawback with addressing this issue purely in the compiler is
that it wasn't possible to get 100% CPython semantics.  The thing that is
different here to CPython is that the __aexit__ method is not looked up in
the context manager until it is needed, which is after the body of the
async with statement has executed.  So if a context manager doesn't have
__aexit__ then CPython raises an exception before the async with is
executed, whereas uPy will raise it after it is executed.  Note that
__aenter__ is looked up at the beginning in uPy because it needs to be
called straightaway, so if the context manager isn't a context manager then
it'll still raise an exception at the same location as CPython.  The only
difference is if the context manager has the __aenter__ method but not the
__aexit__ method, then in that case uPy has different behaviour.  But this
is a very minor, and acceptable, difference.

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

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.

Jeff Epler 05b13fd292 py/objtype: Fix assertion failures in mp_obj_new_type by checking types.

    type("", 3, {})

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.

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.

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.
