Paul Sokolovsky b8ee7ab5b9 py/runtime0.h: Put inplace arith ops in front of normal operations.
This is to allow to place reverse ops immediately after normal ops, so
they can be tested as one range (which is optimization for reverse ops
introduction in the next patch).

Paul Sokolovsky 50b9329eba py/runtime0.h: Move MP_BINARY_OP_DIVMOD to the end of mp_binary_op_t.
It starts a dichotomy of mp_binary_op_t values which can't appear in the
bytecode. Another reason to move it is to VALUES of OP_* and OP_INPLACE_*
nicely adjacent. This also will be needed for OP_REVERSE_*, to be soon
introduced.

Paul Sokolovsky d4d1c45a55 py/runtime0.h: Move relational ops to the beginning of mp_binary_op_t.
This is to allow to encode arithmetic operations more efficiently, in
preparation to introduction of __rOP__ method support.

Paul Sokolovsky 5c603bd0fd py/objlist: Properly implement comparison with incompatible types.
Should raise TypeError, unless it's (in)equality comparison.

tll 68c28174d0 py/objstr: Add check for valid UTF-8 when making a str from bytes.
This patch adds a function utf8_check() to check for a valid UTF-8 encoded
string, and calls it when constructing a str from raw bytes.  The feature
is selectable at compile time via MICROPY_PY_BUILTINS_STR_UNICODE_CHECK and
is enabled if unicode is enabled.  It costs about 110 bytes on Thumb-2, 150
bytes on Xtensa and 170 bytes on x86-64.

Damien George 4a93801c12 all: Update Makefiles and others to build with new ports/ dir layout.
Also renames "stmhal" to "stm32" in documentation and everywhere else.

Damien George d4b75f6b68 py/obj: Fix comparison of float/complex NaN with itself.
IEEE floating point is specified such that a comparison of NaN with itself
returns false, and Python respects these semantics.  This patch makes uPy
also have these semantics.  The fix has a minor impact on the speed of the
object-equality fast-path, but that seems to be unavoidable and it's much
more important to have correct behaviour (especially in this case where
the wrong answer for nan==nan is silently returned).

Paul Sokolovsky 9950865c39 py/objfloat: Fix binary ops with incompatible objects.
These are now returned as "operation not supported" instead of raising
TypeError. In particular, this fixes equality for float vs incompatible
types, which now properly results in False instead of exception. This
also paves the road to support reverse operation (e.g. __radd__) with
float objects.

This is achieved by introducing mp_obj_get_float_maybe(), similar to
existing mp_obj_get_int_maybe().

Damien George 2daacc5cee py/modstruct: Check and prevent buffer-write overflow in struct packing.
Prior to this patch, the size of the buffer given to pack_into() was checked
for being too small by using the count of the arguments, not their actual
size.  For example, a format spec of '4I' would only check that there was 4
bytes available, not 16; and 'I' would check for 1 byte, not 4.

The pack() function is ok because its buffer is created to be exactly the
correct size.

The fix in this patch calculates the total size of the format spec at the
start of pack_into() and verifies that the buffer is large enough.  This
adds some computational overhead, to iterate through the whole format spec.
The alternative is to check during the packing, but that requires extra
code to handle alignment, and the check is anyway not needed for pack().
So to maintain minimal code size the check is done using struct_calcsize.

Damien George 79d5acbd01 py/modstruct: Check and prevent buffer-read overflow in struct unpacking
Prior to this patch, the size of the buffer given to unpack/unpack_from was
checked for being too small by using the count of the arguments, not their
actual size.  For example, a format spec of '4I' would only check that
there was 4 bytes available, not 16; and 'I' would check for 1 byte, not 4.

This bug is fixed in this patch by calculating the total size of the format
spec at the start of the unpacking function.  This function anyway needs to
calculate the number of items at the start, so calculating the total size
can be done at the same time.

Damien George 793d826d9d py/modstruct: In struct.pack, stop converting if there are no args left.
This patch makes a repeat counter behave the same as repeating the
typecode, when there are not enough args.  For example:
struct.pack('2I', 1) now behave the same as struct.pack('II', 1).

Paul Sokolovsky b349479a49 tests/class_new: Add another testcase for __new__/__init__ interaction.
Similar to the existing testcase, but test that returning both value of
native type and instance of another user class from __new__ lead to
__init__ not being called, for better coverage.
2017-09-01 00:43:52 +03:00
Paul Sokolovsky 35be9e805f tests/class_new: Add checks for __init__ being called and other improvements. 2017-08-30 21:33:42 +03:00
Paul Sokolovsky b565c36963 tests/object_new: Better messages, check user __new__() method.
Make messages more verbose and easier to follow and check that user class'
__new__() is not called by object.__new__(user_class).

Paul Sokolovsky 784909ce16 py/objtype: Handle NotImplemented return from binary special methods.
NotImplemented means "try other fallbacks (like calling __rop__
instead of __op__) and if nothing works, raise TypeError". As
MicroPython doesn't implement any fallbacks, signal to raise
TypeError right away.

Paul Sokolovsky 37379a2974 py/objstr: startswith, endswith: Check arg to be a string.
Otherwise, it will silently get incorrect result on other values types,
including CPython tuple form like "foo.png".endswith(("png", "jpg"))
(which MicroPython doesn't support for unbloatedness).

Paul Sokolovsky e3383e9352 py/stream: seek: Consistently handle negative offset for SEEK_SET.
Per POSIX, this is EINVAL, so raises OSError(EINVAL).

Alex Robbins c89254fd0f extmod/modubinascii: Rewrite mod_binascii_a2b_base64.
This implementation ignores invalid characters in the input. This allows
it to decode the output of b2a_base64, and also mimics the behavior of
CPython.

Damien George 025e5f2b33 py/binary: Change internal bytearray typecode from 0 to 1.
The value of 0 can't be used because otherwise mp_binary_get_size will let
a null byte through as the type code (intepreted as byterray).  This can
lead to invalid type-specifier strings being let through without an error
in the struct module, and even buffer overruns.

Eric Poulsen d5191edf7f extmod/modussl_mbedtls.c: Add ussl.getpeercert() method.

A test is included.

Bas van Sisseren a14ce77b28 py/binary.c: Fix bug when packing big-endian 'Q' values.
Without bugfix:

    struct.pack('>Q', 16)
    b'\x00\x00\x00\x10\x00\x00\x00\x00'

With bugfix:

    struct.pack('>Q', 16)
    b'\x00\x00\x00\x00\x00\x00\x00\x10'

instances.

Damien George 3d25d9c7d9 py/objstr: Raise an exception for wrong type on RHS of str binary op.
The main case to catch is invalid types for the containment operator, of
the form str.__contains__(non-str).

There were several different spellings of MicroPython present in comments,
when there should be only one.

Damien George 04552ff71b py: Implement raising a big-int to a negative power.
Before this patch raising a big-int to a negative power would just return
0.  Now it returns a floating-point number with the correct value.

Damien George b86c65d31c extmod/modubinascii: Add check for empty buffer passed to hexlify.
Previous to this patch hexlify(b'', b':') would lead to a bad crash due to
the computed length of the result being -1=0xffffffff.

Paul Sokolovsky bc7659eb59 tests/connect_nonblock: Refactor towards real net_hosted test.
In the future, a special runner for such tests will import each test and
call test() function with an address of test server to use.

Paul Sokolovsky 3f9d59c87a tests/net_inet: Move tests which don't require full Internet to net_hosted.
The idea is that these tests can be run with just a test server running
on a test host, with device under test connecting to it, instead of
requiring Internet connection for testing.

Such setup is however WIP, and some tests in net_hosted/ are so far
written to connect to Internet, as there're not test server written
yet. This is expected to evolve over time.
