tests: Move native for test from pybnative to micropython.

2021-01-29T12:57:10+00:00

And make it generic so it can be run on any target.

tests/micropython/extreme_exc.py: Unlink alloc'd lists earlier in chain.

2020-10-29T12:35:36+00:00

To help the GC collect this memory that's no longer needed after the test.

all: Rename "sys" module to "usys".

2020-09-03T14:10:24+00:00

This is consistent with the other 'micro' modules and allows implementing
additional features in Python via e.g. micropython-lib's sys.

Note this is a breaking change (not backwards compatible) for ports which
do not enable weak links, as "import sys" must now be replaced with
"import usys".

py/persistentcode: Maintain root ptr list of imported native .mpy code.

2020-08-02T12:34:09+00:00

On ports where normal heap memory can contain executable code (eg ARM-based
ports such as stm32), native code loaded from an .mpy file may be reclaimed
by the GC because there's no reference to the very start of the native
machine code block that is reachable from root pointers (only pointers to
internal parts of the machine code block are reachable, but that doesn't
help the GC find the memory).

This commit fixes this issue by maintaining an explicit list of root
pointers pointing to native code that is loaded from an .mpy file.  This
is not needed for all ports so is selectable by the new configuration
option MICROPY_PERSISTENT_CODE_TRACK_RELOC_CODE.  It's enabled by default
if a port does not specify any special functions to allocate or commit
executable memory.

A test is included to test that native code loaded from an .mpy file does
not get reclaimed by the GC.

Fixes #6045.

tests/micropython: Improve .mpy import tests to run on more targets.

2020-07-26T12:44:59+00:00

All imports are now tested to see if the test should be skipped,
UserFile.read is removed, and UserFile.readinto is made more efficient.

tests: Move .mpy import tests from import/ to micropython/ dir.

2020-07-26T12:04:31+00:00

These tests are specific to MicroPython so have a better home in the
micropython/ test subdir, and putting them here allows them to be run by
all targets, not just those that have access to the local filesystem (eg
the unix port).

py/emitnative: Implement binary operations for viper uint operands.

2020-06-26T14:24:04+00:00

uint types in viper mode can now be used for all binary operators except
floor-divide and modulo.

Fixes issue #1847 and issue #6177.

py/parse: Support constant folding of power operator for integers.

2020-05-03T06:23:19+00:00

Constant expression like "2 ** 3" will now be folded, and the special form
"X = const(2 ** 3)" will now compile because the argument to the const is
now a constant.

Fixes issue #5865.

py/parse: Remove unnecessary check in const folding for ** operator.

2020-04-09T06:02:39+00:00

In this part of the code there is no way to get the ** operator, so no need
to check for it.

This commit also adds tests for this, and other related, invalid const
operations.

py/objexcept: Allow compression of exception message text.

2020-04-05T05:02:06+00:00

The decompression of error-strings is only done if the string is accessed
via printing or via er.args.  Tests are added for this feature to ensure
the decompression works.
