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.
User instances are hashable by default (using __hash__ inherited from
"object"). But if __eq__ is defined and __hash__ not defined in particular
class, instance is not hashable.
Having NotImplemented as MP_OBJ_SENTINEL turned out to be problematic
(it needs to be checked for in a lot of places, otherwise it'll crash
as would pass MP_OBJ_IS_OBJ()), so made a proper singleton value like
Ellipsis, both of them sharing the same type.
From https://docs.python.org/3/library/constants.html#NotImplemented :
"Special value which should be returned by the binary special methods
(e.g. __eq__(), __lt__(), __add__(), __rsub__(), etc.) to indicate
that the operation is not implemented with respect to the other type;
may be returned by the in-place binary special methods (e.g. __imul__(),
__iand__(), etc.) for the same purpose. Its truth value is true."
Some people however appear to abuse it to mean "no value" when None is
a legitimate value (don't do that).
* UDP currently not supported
* As there is no way (that I know of) the espconn_regist_connectcb()
callback can recognize on which socket has the connection arrived,
only one listening function at a time is supported
Remove unused and unneeded functions, also create Pin.get_config() that
returns the whole configuration of the pin.
This reduces code size by ~500 bytes.
- by default look for a user.props in the msvc directory, which is more convenient
than the built-in way of looking for such file in the user's home directory
- make git ignore the file
While in STA mode isconnected() returns True when connected to an AP
and the IP has been acquired. In AP mode, WLAN.isconnected() returns
True if at least one connected station is present.
