[issue38210] Intersection of dict view with iterator returns empty set

[Dong-hee Na]

Dong-hee Na  added the comment:

>Interestingly, this doesn't seem to have a negative effect on correctness as 
>the silently omitted unhashable

I think so too.

The error actually raises when adding the object into the set.
https://github.com/python/cpython/blob/818628c2da99ba0376313971816d472c65c9a9fc/Objects/dictobject.c#L4384

Since the target object to be added is dynamically generated, I think that the 
issue does not need to be fixed.
Otherwise, we have to check that all objects are addable to `set` object before 
executing this operation but it looks harmful to performance.

[Erlend E. Aasland]

New submission from Erlend E. Aasland :

pysqlite_collation_callback() currently uses the variable argument function 
PyObject_CallFunctionObjArgs(). Suggesting micro-optimise this by using

What do you mean by this statement? You aren't doing anything to TestClass or 
its instance ("test") in this script. They remain in scope, so they will always 
be referenced.

super is not a pseudo-keyword. It's a regular builtin object that 
interacts with some (quite clever) compiler magic that occurs when 
classes are created.

https://stackoverflow.com/questions/19608134/why-is-python-3-xs-super-magic

The big difference here is that the magic behind super helps to prevent 
serious bugs in user code. super's magic isn't to reduce typing, it is 
to solve a number of real problems with the way people use inheritence.

[issue44603] REPL: exit when the user types exit instead of asking them to explicitly type exit()

[Mark Dickinson]

Mark Dickinson  added the comment:

> the confusion that it can cause when there is a mismatch between the 
> interactive interpreter and noninteractive execution

I've witnessed similar confusion when teaching, using IPython. After 
discovering that you can do

In [1]: import pandas as pd
In [2]: cd datafiles
/Users/mdickinson/Desktop/datafiles
In [3]: df = pd.read_csv("experiment0023.csv")

it's then a common error to copy those lines to a script and expect them to 
work. We learned to recommend that IPython's automagic always be turned off, so 
that at least we could easily explain that "if it starts with a %, it's a magic 
command interpreted by the IPython layer; otherwise it's passed to Python".

If Python grew a similar interpreter layer (which seems like one possible 
solution here), I think we'd have the same issue of making it easy for users to 
distinguish "commands" intended for the interactive interpreter from those 
interpreted by the Python core. I could imagine ending up with users typing 
"%exit" or "!exit" to exit, but one you're adding an extra sigil to distinguish 
your commands from plain old references to Python objects it doesn't seem so 
different from having to type "exit()".

[issue44603] REPL: exit when the user types exit instead of asking them to explicitly type exit()

[Aaron Meurer]

Aaron Meurer  added the comment:

When talking about making exit only work when typed at the interpreter, 
something to consider is the confusion that it can cause when there is a 
mismatch between the interactive interpreter and noninteractive execution, 
especially for novice users. I've seen beginner users add exit() to the bottom 
of Python scripts, presumably because the interpreter "taught" them that you 
have to end with that. 

Now imagine someone trying to use exit as part of control flow 

if input("exit now? ") == "yes":
exit

Unless exit is a full blown keyword, that won't work. And the result is yet 
another instance in the language where users become confused if they run across 
it, because it isn't actually consistent in the language model. 

There are already pseudo-keywords in the language, in particular, super(), but 
that's used to implement something which would be impossible otherwise. Exiting 
is not impossible otherwise, it just requires typing (). But that's how 
everything in the language works. I would argue it's a good thing to reinforce 
the idea that typing a variable by itself with no other surrounding syntax does 
nothing. This helps new users create the correct model of the language in their 
heads.

[issue44473] logging.handlers.QueueHandler acts unexpected

Jack DeVries  added the comment:

I have another question about the docstring in the source beneath 
logging.handlers.QueueHandler.prepare. It says:

> The object returned by this method is enqueued.

But, the prepare method doesn't do the enqueuing operation, it just prepares 
the record and returns it back, so it seems like this statement is not accurate?

[issue44616] Incorrect tracing for "except" with variable

[Barry A. Warsaw]

Barry A. Warsaw  added the comment:

I just retested my test case (see the coveragepy link below) with Python 3.10 
git head and coveragepy git head, and I'm still seeing the misses only in 
Python 3.10:

-- coverage: platform darwin, python 3.10.0-beta-4 ---
Name  Stmts   Miss Branch BrPart  Cover   Missing
-
flufl/lock/__init__.py5  0  0  0   100%
flufl/lock/_lockfile.py 253  0 80  399%   412->415, 
418->420, 535->exit
-


The lines in question:

if is_locked:
try:
os.unlink(self._lockfile)
except OSError as error:
if error.errno not in ERRORS:
raise
# Remove our claim file.
try:
os.unlink(self._claimfile)
except OSError as error:
if error.errno not in ERRORS:
raise

I'm not sure whether coveragepy needs to be updated or whether there are other 
lurking bugs in Python 3.10.  I'm reopening this issue until this is resolved.

[issue44640] Typos in error messages of isinstance() & issubclass()

[wyz23x2]

New submission from wyz23x2 :

>>> isinstance(2, 1)
Traceback (most recent call last):
  ...
TypeError: isinstance() arg 2 must be a type, a tuple of types or a union
>>> issubclass(int, 1)
Traceback (most recent call last):
  ..
TypeError: issubclass() arg 2 must be a class, a tuple of classes, or a union.

1) It should be "an union", not "a union".
2) The punctuation marks aren't the same -- there's a comma before "or" in 
issubclass, but not isinstance(). And issubclass()'s ends with a period, which 
isn't the same with other builtins' messages.

[issue44589] Pattern Matching - duplicate keys in mapping patterns

[Jack DeVries]

Jack DeVries  added the comment:

@brandtbucher, I'm sorry for the miscommunication. I started working on this 
patch at the beginning of the week after message 397215... I'm a new 
contributor too, and I wasn't sure if I would be able to make something that 
worked, so I just kept my mouth shut. Then, all of a sudden, it came together 
and I had a (mostly) working patch.

I'm going to incorporate your review now; thank you for the feedback, and I'm 
very sorry for any toes I may have stepped on.

[issue44639] [sqlite3] Confusing typo "transation"

[John M. Boger]

New submission from John M. Boger :

In the documentation for sqlite3.executescript() in python 3.9+, the pseudoword 
"transation" appears.  I am reasonably sure "transaction" is meant, although it 
could be "translation".

[issue38210] Intersection of dict view with iterator returns empty set

[Łukasz Langa]

Łukasz Langa  added the comment:

This caused an unintentional behavior change in the following code:

>>> {1: 2}.items() & {1: {2: 3}}.items()
set()

Before this change, Python 3.6 - 3.8 behaved like this instead:

>>> {1: 2}.items() & {1: {2: 3}}.items()
Traceback (most recent call last):
  File "", line 1, in 
TypeError: unhashable type: 'dict'

Interestingly, this doesn't seem to have a negative effect on correctness as 
the silently omitted unhashable (k, v) pair is only omitted if it's different 
between the two dictionaries:

>>> {1: {2: 4}}.items() & {1: {2: 3}}.items()
set()
>>> {2: 1, 1: {2: 4}}.items() & {2: 1, 1: {2: 3}}.items()
{(2, 1)}

If it's the same, we still get an error in Python 3.9:

>>> {1: {2: 3}}.items() & {1: {2: 3}}.items()
Traceback (most recent call last):
  File "", line 1, in 
TypeError: unhashable type: 'dict'
>>> {2: 1, 1: {2: 3}}.items() & {2: 1, 1: {2: 3}}.items()
Traceback (most recent call last):
  File "", line 1, in 
TypeError: unhashable type: 'dict'

Brandt Bucher  added the comment:

Thanks for the patch @jack__d! I'll try to find time to review it today.

I do wish you would have coordinated with me here before writing it, though. 
I'd already begun working on a patch with a few new contributors yesterday, as 
I mentioned in my comment.

In the future, please check in with those involved in the PR discussion first 
(*especially* if the issue is already "assigned"). We're doing this for fun, 
too. :)

[issue44618] inspect.signature does not work for datetime classes

[Guido van Rossum]

Guido van Rossum  added the comment:

You're right, it seems specific to built-in *classes* like those in datetime. 
We get the same with inspect.signature(int), since int is also a built-in class.

list[T] is correct. I was pretty puzzled since I thought their code is nearly 
the same, but then I noticed a subtle difference -- GenericAlias checks for 
type(o).__module__ == "typing", while Union checks for o.__module__ == 
"typing", and o.__module__ is wherever the user defines it.

[issue44618] inspect.signature does not work for datetime classes

[Mauricio Villegas]

Mauricio Villegas  added the comment:

> Doesn’t it do that with any built in function?

Sorry. I did not include what is the behavior for other classes. An example 
could be calendar.Calendar. In this case the signature gives:

>>> from calendar import Calendar
>>> import inspect
>>> print(inspect.signature(Calendar.__init__))
(self, firstweekday=0)
>>> print(inspect.signature(Calendar))
(firstweekday=0)

Note that the signature gives firstweekday which is the only init parameter. 
Calendar is not implemented with __new__ so getting the signature would be for 
object, that does not include named parameters.

It also works fine when you implement a class with __new__. For example:

>>> class MyClass:
def __new__(cls, paramA, paramB=1):
obj = object.__new__(cls)
obj.paramA = paramA
obj.paramB = paramB
return obj
>>> print(inspect.signature(MyClass.__new__))
(cls, paramA, paramB=1)
>>> print(inspect.signature(MyClass))
(paramA, paramB=1)

I do think it is a bug specific to the datetime classes.

[issue44638] zipfile.ZipFile is closed when zipfile.Path is closed

[Christian Steinmeyer]

New submission from Christian Steinmeyer :

When executing the code below with the attached zip file (or any other that has 
one or more files directly at root level), I get a "ValueError: seek of closed 
file". It seems, the zipfile handle being part of the `TestClass` instance is 
being closed, when the `zipfile.Path` is garbage collected, when it is no 
longer referenced. Since `zipfile.Path` even takes a `zipfile.Zipfile` as an 
argument, I don't think it is intended? It surprised me at least.


```
import zipfile


class TestClass:
def __init__(self, path):
self.zip_file = zipfile.ZipFile(path)

def iter_dir(self):
return [each.name for each in zipfile.Path(self.zip_file).iterdir()]

def read(self, filename):
with self.zip_file.open(filename) as file:
print(file.read())

root = "zipfile.zip"
test = TestClass(root)
files = test.iter_dir()
test.read(files[0])
```

[issue44637] Quoting issue on header Reply-To

[R. David Murray]

R. David Murray  added the comment:

There is definitely a problem here, though I see a different problem when I run 
it (AttributeError: 'Group' object has no attribute 'local_part', presumably 
because of the ':' not getting escaped correctly).  I believe it applies to any 
address header, not just Reply-To.  Unfortunately I don't have time to 
investigate the cause, at least right now.  An interesting first step on 
diagnosing it might be to produce a minimal example: start deleting special 
characters from inside that quoted string until you find the one (or ones) that 
is triggering it.

Subject: [issue44627] Python terminal cmd line recall

Eryk Sun  added the comment:

By default, reading input from the console uses the console's built-in 
command-line editor. You can clear the console input history with Alt+F7; 
display the history list with F7; navigate in the history list with the up and 
down arrow keys, even when the list isn't displayed; recall the first and last 
entries of the list with page up and page down; and cycle through matching 
command completions with F8.

Having said that, the new implementation of the console in Windows 10 has a bug 
in the "Discard Old Duplicates" history option [1]. Try disabling this option 
in the console's "Properties" dialog, which can be accessed from the Alt+Space 
control menu.

[issue44635] Convert None to NoneType in the union type constructor

[Serhiy Storchaka]

New submission from Serhiy Storchaka :

There is a difference between typing.Union and the builtin union type in 
representing None in __args__:

>>> import typing
>>> typing.Union[int, None].__args__
(, )
>>> typing.Union[int, type(None)].__args__
(, )
>>> (int | None).__args__
(, None)
>>> (int | type(None)).__args__
(, )

The former converts None to NoneType, the latter leaves it as is, and only 
performs conversion in __instancecheck__ and __subclasscheck__. In the 
discussion for issue44606 it was proposed to convert None to NoneType in the 
union type constructor to make more uniform with typing.Union and simplify 
__instancecheck__ and __subclasscheck__.
