When generator raises exception, it is automatically terminated (by setting
its code_state.ip to 0), which interferes with this check.
Triggered in particular by CPython's test_pep380.py.
Exceptions in .close() should be ignored (dumped to sys.stderr, not
propagated), but in uPy, they are propagated. Fix would require
nlr-wrapping .close() call, which is expensive. Bu on the other hand,
.close() is not called often, so maybe that's not too bad (depends,
if it's finally called and that causes stack overflow, there's nothing
good in that). And yet on another hand, .close() can be implemented to
catch exceptions on its side, and that should be the right choice.
The code was apparently broken after 9988618e0e
"py: Implement full func arg passing for native emitter.". This attempts to
propagate those changes to ARM emitter.
The function and corresponding command-line option are only enabled for
the coverage build. They are used to exercise uPy features that can't
be properly tested by Python scripts.
upip is a simple and light-weight package manager for MicroPython modules,
offering subset of pip functionality. upip is part of micropython-lib
project: https://github.com/micropython/micropython-lib/tree/master/upip
This script bootstraps upip by downloading and unpacking it directly from
PyPI repository, with all other packages to be installed with upip itself.
As user_init() is not a true main functions, the stack pointer captured within
is not pointing at the base of the stack. This caused gc_collect being called
with sp being higher than stack_end, causing integer overflow and crashing as
gc tried to scan almost the entire address space.
esp8266 port now has working raw and friendly REPL, as well as working
soft reset (CTRL-D at REPL, or raise SystemExit).
tools/pyboard.py now works with esp8266 port.
