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.
Can complete names in the global namespace, as well as a chain of
attributes, eg pyb.Pin.board.<tab> will give a list of all board pins.
Costs 700 bytes ROM on Thumb2 arch, but greatly increases usability of
REPL prompt.
Each result is displayed like this:
ssid='MySSID', bssid=b'\xc0J\x00z.\xcc', security=2, channel=None, rssi=-74
The CC3200 doesn't provide channel info, that why is 'None'.
This is actually a workaround Ter Term's issue of not obeying to the
telnet options that the server is sending. Therefore, we must buffer
chars until either a '\r' or the max length of the username/password
is received.
This doesn't handle case fo enclosed except blocks, but once again,
sys.exc_info() support is a workaround for software which uses it
instead of properly catching exceptions via variable in except clause.
The implementation is very basic and non-compliant and provided solely for
CPython compatibility. The function itself is bad Python2 heritage, its
usage is discouraged.
Before this patch a "with" block needed to create a bound method object
on the heap for the __exit__ call. Now it doesn't because we use
load_method instead of load_attr, and save the method+self on the stack.
