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).
tinytest is written with the idea that tests won't write to stdout, so it
prints test name witjout newline, then executes test, then writes status.
But MicroPython tests write to stdout, so the test output becomes a mess.
So, instead print it like:
# starting basics/andor.py
... test output ...
basics/andor.py: OK
If TEST is defined, file it refers to will be used as the testsuite
source (should be generated with tools/tinytest-codegen.py).
"make-bin-testsuite" script is introduce to build such a binary.
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".
Some compilers can treat enum types as signed, in which case 3 bits is not
enough to encode all mp_raw_code_kind_t values. So change the type to
mp_uint_t.
Instead of passing thru more and more options from tinytest-codegen to
run-tests --list-tests, pipe output of run-tests --list-tests into
tinytest-codegen.
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.
Because otherwise the function can return with data still waiting to be
clocked out, and CS might then be disabled before the SPI transaction is
complete. Fixes issue #3487.
Gets passed to run-tests --list-tests to get actual list of tests to use.
If --target= is not given, legacy set hardcoded in tinytest-codegen itself
is used.
Also, get rid of tinytest test groups - they aren't really used for
anything, and only complicate processing. Besides, one of the next
step is to limit number of tests per a generated file to control
the binary size, which also will require "flat" list of tests.
Lists tests to be executed, subject to all other filters requested. This
options would be useful e.g. for scripts like tools/tinytest-codegen.py,
which currently contains hardcoded filters for particular a particular
target and can't work for multiple targets.
The way tinytest was used in qemu-arm test target is that it didn't test
much. MicroPython tests are based on matching the test output against
reference output, but qemu-arm's implementation didn't do that, it
effectively tested just that there was no exception during test
execution. "upytesthelper" wrapper was introduce to fix it, so switch
test implementation to use it.
This requires passing different CFLAGS when building the firmware, so
split out test-related parts to Makefile.test.

Also, fix PEP8 and other codestyle issues.
Tinytest is classical assert-style framework, but MicroPython tests work
in different way - they produce content, and that content should be matched
against expected one to see if test passes. upytesthelper exactly adds
helper functions to make that possible.
Code lineage:
osdebug() is based loosely on the version in esp8266, but there didn't
seem to be an obvious way of choosing a particular UART. The basic
behavior is the same, though: provide None, and logging is disabled;
provide an integer and logging is restored to the default level.
To build on that, and because the IDF provides more functionality, a
second parameter has now been implemented which allows the active log
level to be set:
esp.osdebug(uart[, level])
The module has a corresponding set of LOG_ values to set this accordingly.
When configuring a static set of values with ifconfig() the DNS was not
being set. This patch fixes that, and additionally uses the tcpip_adapter
API to ensure it is thread safe.
