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 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 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.
2018-05-11 17:37:16 +10:00
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 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.

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

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.

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.
2018-04-04 01:43:16 +10:00
Damien George bcfff4fc98 tests/basics/iter1.py: Add more tests for walking a user-defined iter.
Some code in mp_iternext() was only tested by the native emitter, so the
tests added here test this function using just the bytecode emitter.
2018-03-30 14:23:13 +11:00
Damien George f50b64cab5 py/runtime: Be sure that non-intercepted thrown object is an exception.
The VM expects that, if mp_resume() returns MP_VM_RETURN_EXCEPTION, then
the returned value is an exception instance (eg to add a traceback to it).
It's possible that a value passed to a generator's throw() is not an
exception so must be explicitly checked for if the thrown value is not
intercepted by the generator.

Thanks to @jepler for finding the bug.

Damien George 3280788195 py/runtime: Check that keys in dicts passed as ** args are strings.
Prior to this patch the code would crash if a key in a ** dict was anything
other than a str or qstr.  This is because mp_setup_code_state() assumes
that keys in kwargs are qstrs (for efficiency).

Thanks to @jepler for finding the bug.

Damien George c607b58efe tests: Move heap-realloc-while-locked test from C to Python.
This test for calling gc_realloc() while the GC is locked can be done in

Damien George 955ee6477f py/formatfloat: Fix case where floats could render with negative digits.
Prior to this patch, some architectures (eg unix x86) could render floats
with "negative" digits, like ")".  For example, '%.23e' % 1e-80 would come
out as "1.0000000000000000/)/(,*0e-80".  This patch fixes the known cases.
2018-03-01 17:00:02 +11:00
Damien George 7b050fa76c py/formatfloat: Fix case where floats could render with a ":" character.
Prior to this patch, some architectures (eg unix x86) could render floats
with a ":" character in them, eg 1e+39 would come out as ":e+38" (":" is
just after "9" in ASCII so this is like 10e+38).  This patch fixes some of
these cases.
2018-03-01 16:02:59 +11:00
Damien George bc12eca461 py/formatfloat: Fix rounding of %f format with edge-case FP values.
Prior to this patch the %f formatting of some FP values could be off by up
to 1, eg '%.0f' % 123 would return "122" (unix x64).  Depending on the FP
precision (single vs double) certain numbers would format correctly, but
others wolud not.  This patch should fix all cases of rounding for %f.

Damien George 22ade2f5c4 py/vm: Fix case of handling raised StopIteration within yield from.
This patch concerns the handling of an NLR-raised StopIteration, raised
during a call to mp_resume() which is handling the yield from opcode.

Previously, commit 6738c1dded introduced code
to handle this case, along with a test.  It seems that it was lucky that
the test worked because the code did not correctly handle the stack pointer
(sp).

Furthermore, commit 79d996a57b improved the
way mp_resume() propagated certain exceptions: it changed raising an NLR
value to returning MP_VM_RETURN_EXCEPTION.  This change meant that the
test introduced in gen_yield_from_ducktype.py was no longer hitting the
code introduced in 6738c1dded.

The patch here does two things:

1. Fixes the handling of sp in the VM for the case that yield from is
   interrupted by a StopIteration raised via NLR.

2. Introduces a new test to check this handling of sp and re-covers the
   code in the VM.

Damien George 6dad088569 tests/float: Adjust float-parsing tests to pass with only a small error.
Float parsing (both single and double precision) may have a relative error

These new tests cover cases that can't be reached from Python and get
coverage of py/mpz.c to 100%.

These "unreachable from Python" pieces of code could be removed but they
form an integral part of the mpz C API and may be useful for non-Python
usage of mpz.

Damien George 77a62d8b5a tests/stress: Add test to create a dict beyond "maximum" rehash size.
There is a finite list of ascending primes used for the size of a hash
table, and this test tests that the code can handle a dict larger than the
maximum value in that list of primes.  Adding this tests gets py/map.c to
100% coverage.

Damien George 160d670868 py/objdeque: Protect against negative maxlen in deque constructor.
Otherwise passing -1 as maxlen will lead to a zero allocation and
subsequent unbound buffer overflow in deque.append() because i_put is

Damien George 4e469085c1 py/objstr: Protect against creating bytes(n) with n negative.
Prior to this patch uPy (on a 32-bit arch) would have severe issues when
calling bytes(-1): such a call would call vstr_init_len(vstr, -1) which
would then +1 on the len and call vstr_init(vstr, 0), which would then
round this up and allocate a small amount of memory for the vstr.  The
bytes constructor would then attempt to zero out all this memory, thinking
it had allocated 2^32-1 bytes.

Damien George 165aab12a3 py/repl: Generalise REPL autocomplete to use qstr probing.
This patch changes the way REPL autocomplete finds matches.  It now probes
the target object for all qstrs via mp_load_method_maybe to look for a
match with the given input string.  Similar to how the builtin dir()
function works, this new algorithm now find all methods and instances of
user-defined classes including attributes of their parent classes.  This
helps a lot at the REPL prompt for user-discovery and to autocomplete names
even for classes that are derived.

The downside is that this new algorithm is slower than the previous one,
and in particular will be slower the more qstrs there are in the system.
But because REPL autocomplete is primarily used in an interactive way it is
not that important to make it fast, as long as it is "fast enough" compared
to human reaction.

On a slow microcontroller (CPU running at 16MHz) the autocomplete time for
a list of 35 names in the outer namespace (pressing tab at a bare prompt)
takes about 160ms with this algorithm, compared to about 40ms for the
previous implementation (this time includes the actual printing of the
names as well).  This time of 160ms is very reasonable especially given the
new functionality of listing all the names.

This patch also decreases code size by:

   bare-arm:    +0
minimal x86:  -128
   unix x64:  -128
unix nanbox:  -224
      stm32:   -88
     cc3200:   -80
    esp8266:   -92
      esp32:   -84
2018-02-19 16:12:44 +11:00
Damien George 98647e83c7 py/modbuiltins: Simplify and generalise dir() by probing qstrs.
This patch improves the builtin dir() function by probing the target object
with all possible qstrs via mp_load_method_maybe.  This is very simple (in
terms of implementation), doesn't require recursion, and allows to list all
methods of user-defined classes (without duplicates) even if they have
multiple inheritance with a common parent.  The downside is that it can be
slow because it has to iterate through all the qstrs in the system, but
the "dir()" function is anyway mostly used for testing frameworks and user
introspection of types, so speed is not considered a priority.

In addition to providing a more complete implementation of dir(), this
patch is simpler than the previous implementation and saves some code
space:

   bare-arm:   -80
minimal x86:   -80
   unix x64:   -56
unix nanbox:   -48
      stm32:   -80
     cc3200:   -80
    esp8266:  -104
      esp32:   -64

Damien George d77da83d55 py/objrange: Implement (in)equality comparison between range objects.
This feature is not often used so is guarded by the config option
MICROPY_PY_BUILTINS_RANGE_BINOP which is disabled by default.  With this
option disabled MicroPython will always return false when comparing two
range objects for equality (unless they are exactly the same object
instance).  This does not match CPython so if (in)equality between range
objects is needed then this option should be enabled.

Enabling this option costs between 100 and 200 bytes of code space
depending on the machine architecture.

Damien George 49e0dd54e6 tests/run-tests: Capture any output from a crashed uPy execution.
Instead of putting just 'CRASH' in the .py.out file, this patch makes it so
any output from uPy that led to the crash is stored in the .py.out file, as
well as the 'CRASH' message at the end.

Damien George b75cb8392b py/parsenum: Fix parsing of floats that are close to subnormal.
Prior to this patch, a float literal that was close to subnormal would
have a loss of precision when parsed.  The worst case was something like
float('10000000000000000000e-326') which returned 0.0.

Damien George b45c8c17f0 py/objtype: Check and prevent delete/store on a fixed locals map.
Note that the check for elem!=NULL is removed for the

return non-NULL for such a case.

Ayke van Laethem 7642785881 extmod/vfs_fat_file: Implement SEEK_CUR for non-zero offset.
CPython doesn't allow SEEK_CUR with non-zero offset for files in text mode,
and uPy inherited this behaviour for both text and binary files.  It makes
sense to provide full support for SEEK_CUR of binary-mode files in uPy, and
to do this in a minimal way means also allowing to use SEEK_CUR with
non-zero offsets on text-mode files.  That seems to be a fair compromise.

Paul Sokolovsky 6364401666 py/objgenerator: Allow to pend an exception for next execution.
This implements .pend_throw(exc) method, which sets up an exception to be
triggered on the next call to generator's .__next__() or .send() method.
This is unlike .throw(), which immediately starts to execute the generator
to process the exception. This effectively adds Future-like capabilities
to generator protocol (exception will be raised in the future).

The need for such a method arised to implement uasyncio wait_for() function
efficiently (its behavior is clearly "Future" like, and normally would
require to introduce an expensive Future wrapper around all native
couroutines, like upstream asyncio does).

py/objgenerator: pend_throw: Return previous pended value.

This effectively allows to store an additional value (not necessary an
exception) in a coroutine while it's not being executed. uasyncio has
exactly this usecase: to mark a coro waiting in I/O queue (and thus
not executed in the normal scheduling queue), for the purpose of
implementing wait_for() function (cancellation of such waiting coro
by a timeout).

Paul Sokolovsky 103eeffcd9 tests/run-tests: Skip running feature checks for --list-tests/--write-exp.
The whole idea of --list-tests is that we prepare a list of tests to run
later, and currently don't have a connection to target board. Similarly
for --write-exp - only "python3" binary would be required for this operation,
not "micropython".

Paul Sokolovsky 3233537a15 tests/run-tests: Don't test for --target=unix with "pyb is None".

2017-12-14 13:36:06 +02:00
Paul Sokolovsky 64bb32d87f tests/run-tests: Add composable --include and --exclude options.
The idea that --list-tests would be enough to produce list of tests for
tinytest-codegen didn't work, because normal run-tests processing heavily
relies on dynamic target capabilities discovery, and test filtering happens
as the result of that.

So, approach the issue from different end - allow to specify arbitrary
filtering criteria as run-tests arguments. This way, specific filters
will be still hardcoded, but at least on a particular target's side,
instead of constant patching tinytest-codegen and/or run-tests.

Paul Sokolovsky da34b6ef45 tests: Fix few test for proper "skipped" detection with qemu-arm's tinytest.
"Builtin" tinytest-based testsuite as employed by qemu-arm (and now
generalized by me to be reusable for other targets) performs simplified
detection of skipped tests, it treats as such tests which raised SystemExit
(instead of checking got "SKIP" output). Consequently, each "SKIP" must
be accompanied by SystemExit (and conversely, SystemExit should not be
used if test is not skipped, which so far seems to be true).

These tests involves testing allocation-free function calling, and in strict

Paul Sokolovsky e02cb9ec31 tests/heapalloc_*: Refactor some tests to work in strict stackless mode.
In strict stackless mode, it's not possible to make a function call with

Damien George 84895f1a21 py/parsenum: Improve parsing of floating point numbers.
This patch improves parsing of floating point numbers by converting all the
digits (integer and fractional) together into a number 1 or greater, and
then applying the correct power of 10 at the very end.  In particular the
multiple "multiply by 0.1" operations to build a fraction are now combined
together and applied at the same time as the exponent, at the very end.

This helps to retain precision during parsing of floats, and also includes
a check that the number doesn't overflow during the parsing.  One benefit
is that a float will have the same value no matter where the decimal point
is located, eg 1.23 == 123e-2.

Damien George 5e34a113ea py/runtime: Add MP_BINARY_OP_CONTAINS as reverse of MP_BINARY_OP_IN.
Before this patch MP_BINARY_OP_IN had two meanings: coming from bytecode it
meant that the args needed to be swapped, but coming from within the
runtime meant that the args were already in the correct order.  This lead
to some confusion in the code and comments stating how args were reversed.
It also lead to 2 bugs: 1) containment for a subclass of a native type
didn't work; 2) the expression "{True} in True" would illegally succeed and
return True.  In both of these cases it was because the args to
MP_BINARY_OP_IN ended up being reversed twice.

To fix these things this patch introduces MP_BINARY_OP_CONTAINS which
corresponds exactly to the __contains__ special method, and this is the
operator that built-in types should implement.  MP_BINARY_OP_IN is now only
emitted by the compiler and is converted to MP_BINARY_OP_CONTAINS by
swapping the arguments.

Damien George f36975b679 tests/net_inet: Update tls test to work with CPython and incl new site.
CPython only supports the server_hostname keyword arg via the SSLContext
object, so use that instead of the top-level ssl.wrap_socket.  This allows
the test to run on CPython the same as uPy.

Also add the "Host:" header to correctly make a GET request (for URLs that
are hosted on other servers).  This is not strictly needed to test the SSL
connection but helps to debug things when printing the response.

Damien George 25e140652b py/modmath: Add full checks for math domain errors.
This patch changes how most of the plain math functions are implemented:
there are now two generic math wrapper functions that take a pointer to a
math function (like sin, cos) and perform the necessary conversion to and
from MicroPython types.  This helps to reduce code size.  The generic
functions can also check for math domain errors in a generic way, by
testing if the result is NaN or infinity combined with finite inputs.

The result is that, with this patch, all math functions now have full
domain error checking (even gamma and lgamma) and code size has decreased
for most ports.  Code size changes in bytes for those with the math module
are:

   unix x64:  -432
unix nanbox:  -792
      stm32:   -88
    esp8266:   +12

Tests are also added to check domain errors are handled correctly.

Damien George 2ac1364688 py/objset: Check that RHS of a binary op is a set/frozenset.
CPython docs explicitly state that the RHS of a set/frozenset binary op
must be a set to prevent user errors.  It also preserves commutativity of
the ops, eg: "abc" & set() is a TypeError, and so should be set() & "abc".

This change actually decreases unix (x64) code by 160 bytes; it increases
stm32 by 4 bytes and esp8266 by 28 bytes (but previous patch already
introduced a much large saving).
