Jeff Epler cd0ed65b29 mp_obj_instance_make_new: clearer way to avoid null pointer dereference 2019-10-10 13:25:24 +09:00
Jeff Epler 8fbe19b993 mp_obj_instance_make_new: avoid undefined behavior
If kw_args is NULL then memcpy() gets a NULL source argument.
This is undefined behavior under the C standard, even if 0 bytes
are being copied.

This problem was found using clang 7's scan-build static analyzer.

Jeff Epler 85f0048d22 mp_bytecode_print_str: avoid undefined behavior
Left shift of negative numbers is undefined in the "C" standard.  Multiplying
by 128 has the intended effect (in the absence of integer overflow, anyway),
can be implemented using the same shift instruction, but does not invoke
undefined behavior.

This problem was found using clang 7's scan-build static analyzer.

Jeff Epler 46b6870ffa gc_alloc: Remove redundant 'collected' assignment
The remaining assignment was added in upstream micropython; the
deleted assignment was added in circuitpython as part of the long-lived
object area feature.  During the merge, the redundant assignment
was not removed.

(since collected is a local variable and no pointers to it escape,
it doesn't seem possible for the placement of the assignment before
or after GC_ENTER() is important)

This diagnostic was found by clang 7's scan-build static analyzer.

Left shift of negative numbers is undefined in the "C" standard.  Multiplying
by 256 has the intended effect (in the absence of integer overflow, anyway),
can be implemented using the same shift instruction, but does not invoke
undefined behavior.

While finding sources of clicks and buzzes in nrf i2sout, I identified
this site as one which could be long running.  Reproducer code was to
play a 22.05kHz sample and repeatedly print `os.listdir('')`

Jeff Epler 47d6dd843e audioio: By default, be compatible with 4.x
Testing performed: That the shipped .mpy files on a PyPortal (CP 4.x)
still work (play audio) with this branch, instead of erroring because
`WaveFile` can't be found in `audioio`.

Flash usage grew by 28 bytes.  (I expected 24, there must be some other
effect on size/alignment that I didn't predict)

Jeff Epler 076cbcc4f8 cicuitpy_mpconfg.h: Define RUN_BACKGROUND_TASKS
In #2013, @danh says:
    My choice of where to put the semicolon is deliberate,
    so that we can say

        RUN_BACKGROUND_TASKS;

    not have a redundant semicolon, and not confuse C code formatting.

Jeff Epler 3eb418af39 py: mp_obj_tuple_get: accept any item which can use tuple_getiter
.. such as namedtuple and attrtuple objects.  This is the same
predicate used elsewhere in the file to check for adequate compatibility
between the types.

This was discovered due to crashing `time.time()` on the nrf port.

Jeff Epler c4f3a02b3b makeqstrdata: permit longer "compressed" outputs
It is possible for this routine to expand some inputs, and in fact
it does for certan strings in the proposed Korean translation of
CircuitPython (#1858).  I did not determine what the maximum
expansion is -- it's probably modest, like len()/7+2 bytes or
something -- so I tried to just make enc[] an adequate
over-allocation, and then ensured that all the strings in the
proposed ko.po now worked.  The worst actual expansion seems to be a
string that goes from 65 UTF-8-encoded bytes to 68 compressed bytes
(+4.6%).  Only a few out of all strings are reported as
non-compressed.

Jeff Epler 6b44e40ee8 audiocore: Factor from audioio
When nrf pwm audio is introduced, it will be called `audiopwmio`.  To
enable code sharing with the existing (dac-based) `audioio`, factor
the sample and mixer types to `audiocore`.

INCOMPATIBLE CHANGE: Now, `Mixer`, `RawSample` and `WaveFile` must
be imported from `audiocore`, not `audioio`.

Add support for grayscale displays that are < 8 bit depth.
This also improves Palette so it stores the original RGB888 colors.

Lastly, it adds I2CDisplay as a display bus to talk over I2C. Particularly
useful for the SSD1306.
