set_equal is called only from set_binary_op, and this guarantees that the
second arg to set_equal is always a set or frozenset. So there is no need
to do a further check.
Previously, testing of stackless build happened (manually) in
travis-stackless branch. However, stackless offers important
featureset, so it's worth to test it as a part of the main
CI. Strict stackless is used because it's the "real" stackless
build, which avoids using C stack as much as possible (non-strict
just prefers heap over C stack, but may end up using the latter).
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".
