[issue39135] time.get_clock_info() documentation still has 'clock' name

[Michael Wayne Goodman]

New submission from Michael Wayne Goodman :

The documentation for Python 3.8 and higher still refer to 'clock' as an 
accepted 'name' argument for time.get_clock_info() that returns a namespace 
readable by time.clock(), despite time.clock() being removed since Python 3.8.

See the first bullet point in the function documentation: 
https://docs.python.org/3.8/library/time.html#time.get_clock_info

In Python 3.8, calling time.get_clock_info('clock') raises "ValueError: unknown 
clock", so it seems the bug is only in the documentation.

[issue39132] Adding funcitonality to determine if a constant string node is triple quoted

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

It is impossible because of using newline escaping and string literal 
concatenation. In the following examples 
lineno != end_lineno, but strings use single quotes:

print('Hello '
  'world!')

print('Hello\
 world!')

Triple quotes can be also used for strings which occupy a single line of code 
and do not contain \n:

print("""exec("print('Hi!')")""")

We cannot also distinguish 1234 from 0x4_d2 and 1234.0 from 1.234e3 at the AST 
level.

I'm not sure the usage should be covered by "Abstract" syntax tree.

Isn't it a "Concrete" syntax tree?

[issue39134] can't construct dataclass as ABC (or runtime check as data protocol)

[Alexander Hirner]

New submission from Alexander Hirner :

At runtime, we want to check whether objects adhere to a data protocol. This is 
not possible due to problematic interactions between ABC and @dataclass.

The attached file tests all relevant yet impossible cases. Those are:

1) A(object): Can't check due to "Protocols with non-method members don't 
support issubclass()" (as outlined in PEP 554)
2) B(ABC): "Can't instantiate abstract class B with abstract methods x, y"
3) C(Protocol): same as A or same as B if @property is @abstractmethod

The problem can be solved in two parts. First allowing to implement 
@abstractproperty in a dataclass (B). This doesn't involve typing and enables 
the expected use case of dataclass+ABC. I analysed this problem as follows:
Abstract properties evaluate to a default of property, not to 
dataclasses.MISSING. Hence, `dataclasses._init_fn` throws TypeError because of 
deriving from class vars without defaults.

Second, eliding the exception of @runtime_checkable Protocols with non-method 
members if and only if the the the protocol is in its MRO. I didn't think that 
through fully, but instantiation could e.g. fail for missing implementations as 
expected from ABC behaviour (see case D in attached file). I'm not sure about 
the runtime overhead of this suggestion.

Give OS.  Provide specific code and describe specific problem.  Run the code 
directly with python from a command line to determine if IDLE is really

[issue16399] argparse: append action with default list adds to list instead of overriding

[Roy Smith]

Roy Smith  added the comment:

I just got bit by this in Python 3.5.3.

I get why it does this.  I also get why it's impractical to change the behavior 
now.  But, it really isn't the obvious behavior, so it should be documented at 
https://docs.python.org/3.5/library/argparse.html?highlight=argparse#default.

[issue39133] threading lib. working improperly on idle window

[Abhijeet]

New submission from Abhijeet :

Threading library's Thread and start functions not showing predicted result on 
idle. Especially, newline is not invoked between two threads while sometimes 
gets invoked in result. Often, running of code stops after thread ends i.e no 
further execution. Version - 3.8.0 exe installer

[issue37509] OSError preadv()

[YoSTEALTH]

YoSTEALTH  added the comment:

I am closing this topic as its right for python to raise OSError as `-errno` 
must be assigned to e.g. `OSError(-errno, os.strerror(-errno))` to raise 
appropriate exception.

[issue39106] Add suggestions to argparse error message output for unrecognized arguments

[hai shi]

hai shi  added the comment:

I checked some other common clis and it is show all right available options 
too. So I thought the argparse's help function is good enough too ;)

```
$ ps -etest
error: TTY could not be found

Usage:
 ps [options]

 Try 'ps --help '
  or 'ps --help '
 for additional help text.

For more details see ps(1).
```

```
$ top test
top: unknown option 't'
Usage:
  top -hv | -bcHiOSs -d secs -n max -u|U user -p pid(s) -o field -w [cols]
```
