[issue32133] documentation: numbers module nitpick

[Sergey B Kirpichev]

Sergey B Kirpichev  added the comment:

Maybe some methods from the Complex class could be moved to the Number class?

I think, that something like the ring structure (probably even a commutative 
ring) is expected from the number classes in the Python.  I.e. there should be 
__add__/__sub__/__mul__/__pos__/__neg__/__pow__/etc.  But not 
__truediv__/__floordiv__.

Even simpler idea: move the __eq__ method to the Number class.

Then it would be impossible to instantiate a Number.

[issue44140] WeakKeyDictionary should support lookup by id instead of hash

[conchylicultor]

New submission from conchylicultor :

WeakKeyDictionary are great to "associate additional data with an object owned 
by other parts of an application", as quoted from the doc: 
https://docs.python.org/3/library/weakref.html#weakref.WeakKeyDictionary

However, this currently only works for hashable types. Non-hashables are not 
supported:

```
@dataclass
class A:
  pass

a = A()

d = weakref.WeakKeyDictionary()
d[a] = 3  # TypeError: unhashable type: 'A'
```

With regular dict, this could be easilly solved by using `d[id(a)] = 3`, but 
WeakKeyDictionary don't accept `int` of course. I cannot wrap the object either 
as the weakref would not be attached to the original object, but the wrapper.

It would be great to be able to force WeakKeyDictionary to perform lookup on 
`id` internally. Like `d = WeakKeyDictionary(use_id_lookup=True)`

[issue44137] importlib.resources.path raises RuntimeError when FileNotFoundError is raise in context manager

[Miguel Brito]

Miguel Brito  added the comment:

I can reproduce this. From what I can see the issue is that 
`importlib.resources.path` intentionally suppresses `FileNotFoundError` errors.

https://github.com/python/cpython/blob/main/Lib/importlib/resources.py#L138

Based on `importlib.resources.path` docstring I think this is to avoid raising 
an exception if the file is deleted before the context manager exits.

On contextlib.py, since type is not None, it will try to throw the exception 
but since it's supressed nothing will happen and the code will reach the end by 
raising the RuntimeError.

https://github.com/python/cpython/blob/main/Lib/contextlib.py#L151

If I'm not mistaken, this is the test that verifies that behaviour: 
https://github.com/python/cpython/blob/main/Lib/test/test_importlib/test_path.py#L51


I'm not a core dev but it looks like it's an intentional behaviour.

Maybe the docs should be more clear about this. It's not obvious to me when I 
read the docs.

[issue44141] Getting error while importing ssl "import _ssl ImportError: DLL load failed: The specified procedure could not be found."

[Tarnum]

New submission from Tarnum :

Hello! I'm using specifically crafted Python 3.7.1 for NT 5.2 x86 (Server 2003 
R2) and cannot upgrade Python to later versions.
I always building OpenSSL myself using compatible version of MSYS2 with perl 
5.22.
Compiled DLLs of OpenSSL 1.1.1k works fine for me (libcrypto-1_1.dll and 
libssl-1_1.dll in C:\Python37\DLLs\).
But when I try building OpenSSL 3.0.0 alpha 16 (repacing libcrypto-3.dll with 
libcrypto-1_1.dll and libssl-3.dll with libssl-1_1.dll in
Makefile and util\mkdef.pl) I got this error because of OpenSSL 3.0 backwards 
incompatibility:

import ssl
File "C:\Python37\lib\ssl.py", line 98, in 
import _ssl (C:\Python37\DLLs\_ssl.pyd) # if we can't import it, let the error 
propagate
ImportError: DLL load failed: The specified procedure could not be found.

What could I do to fix it? Thanks in advance!

[issue44135] issubclass documentation doesn't explain tuple semantic

[Ken Jin]

Ken Jin  added the comment:

I agree that this subtlety could be expressed better. Thanks for the catch! 
Would you like to work on this?

BTW, only Python 3.9 and higher are still receiving bugfixes (including doc 
fixes). The older versions are either security fixes only or end of life :).

[issue13498] os.makedirs exist_ok documentation is incorrect, as is some of the behavior

[Bonifacio]

Bonifacio  added the comment:

I just read this issue's history and it looks like it is out of date. The docs 
now match the behaviour.

> If the file exists but the mode is different than that specified (or 
> defaulted) after applying the umask, then an error is raised regardless of 
> the value of exist_ok.

This isn’t true anymore.

> The above wording also implies that if the directory exists but has a 
> different mode, that the mode will be changed.  Again, this is not what the 
> code does.

The docs now state the behaviour explicitly: “The file permission bits of 
existing parent directories are not changed.”

This means the reported issue no longer exists. But somewhere along the 
discussion it became one about adding a new flag to control the behaviour when 
there are mode mismatches. I tried applying Hynek’s patch locally, but it 
doesn’t work anymore. If we want to go ahead with adding this new flag we would 
have to create a new patch. If we want to drop the change then this issue can 
be closed.

If we decide to go with the flag addition I’m glad to help fixing Hynek’s 
patch’s incompatibilities if he is ok with that.

[issue44142] ast.unparse: visually better code generation

[Batuhan Taskaya]

New submission from Batuhan Taskaya :

This issue is for tracking possible places where we could generate better code 
on ast.unparse (better as in more closely to what people are actually writing 
than our naive implementation). 

Examples;
>>> import ast
>>> ast.unparse(ast.parse('a, b, c = [1,2,3]'))
'(a, b, c) = [1, 2, 3]'

could be
>>> ast.unparse(ast.parse('a, b, c = [1,2,3]'))
'a, b, c = [1, 2, 3]'

OR
>>> print(ast.unparse(ast.parse('if value := d.get("something"): 
>>> print(value)')))
if (value := d.get('something')):
print(value)

could be
>>> print(ast.unparse(ast.parse('if value := d.get("something"): 
>>> print(value)')))
if value := d.get('something'):
print(value)

We could even go further with the long line unpacking (which would definitely 
require some sort of clever algorithm for nested structures). 

>>> source = '[\n' + '\tsomething,\n' * 20 + ']'
>>> print(source)
[
something,
something,
something,
something,
something,
something,
something,
something,
something,
something,
something,
something,
something,
something,
something,
something,
something,
something,

something,
]
>>> print(ast.unparse(ast.parse(source)))
[something, something, something, something, something, something, something, 
something, something, something, something, something, something, something, 
something, something, something, something, something, something]

[issue41486] Add _BlocksOutputBuffer for bz2/lzma/zlib module

[Ma Lin]

Ma Lin  added the comment:

Sorry, for the (init_size > UINT32_MAX) problem, I have a better solution.

Please imagine this scenario:
- before the patch
- in 64-bit build
- use zlib.decompress() function
- the exact decompressed size is known and > UINT32_MAX (e.g. 10 GiB)

If set the `bufsize` argument to the decompressed size, it used to have a fast 
path:

zlib.decompress(data, bufsize=10*1024*1024*1024)

Fast path when (the initial size == the actual size):
https://github.com/python/cpython/blob/v3.9.5/Modules/zlibmodule.c#L424-L426

https://github.com/python/cpython/blob/v3.9.5/Objects/bytesobject.c#L3008-L3011

But in the current code, the initial size is clamped to UINT32_MAX, so there 
are two regressions:

1. allocate double RAM. (~20 GiB, blocks and the final bytes)
2. need to memcpy from blocks to the final bytes.

PR 26143 uses an UINT32_MAX sliding window for the first block, now the initial 
buffer size can be greater than UINT32_MAX.

_BlocksOutputBuffer_Finish() already has a fast path for single block. 
Benchmark this code:

zlib.decompress(data, bufsize=10*1024*1024*1024)

  time  RAM
before: 7.92 sec, ~20 GiB
after:  6.61 sec,  10 GiB
(AMD 3600X, DDR4-3200, decompressed data is 10_GiB * b'a')

Maybe some user code rely on this corner case.
This should be the last revision, then there is no regression in any case.

The parser currently crashes when raising exceptions when the error indicator 
set. Reproducer:

[issue44132] Local import conflict with system import

[Ned Deily]

Ned Deily  added the comment:

Python is behaving as documented here. The problem is that you have a package 
named 'xml' which conflicts with the package of the same name in the standard 
library (https://docs.python.org/3/library/xml.html) which may cause conflicts 
for other packages depending on the import search order. The documentation for 
sys.path (https://docs.python.org/3/library/sys.html#sys.path) explains what 
you are seeing:

'As initialized upon program startup, the first item of this list, path[0], is 
the directory containing the script that was used to invoke the Python 
interpreter. If the script directory is not available (e.g. if the interpreter 
is invoked interactively or if the script is read from standard input), path[0] 
is the empty string, which directs Python to search modules in the current 
directory first. Notice that the script directory is inserted before the 
entries inserted as a result of PYTHONPATH."

So, in your first example, "testdriver" will be the first entry on sys.path 
because the script was invoked from there; this mean 'xml' will be imported 
from the "testdriver" directory. But, in your second example, the script is 
read from the command line via the -c argument so the first sys.path entry will 
be '' and the current directory is 'python_bug' so now your 'xml' package is no 
longer found first.

This is a common pitfall and is sometimes called the "name shadowing trap" (see 
http://python-notes.curiousefficiency.org/en/latest/python_concepts/import_traps.html#the-name-shadowing-trap).
  The easiest and most robust solution is to avoid using package and module 
names that conflict with those in the standard library.

[issue44123] make function parameter sentinel value true singletons

[Tal Einat]

Tal Einat  added the comment:

> And what you need is just to not pass to the wrapped function arguments which 
> were not passed to wrapper. *args and **kwargs do not contain arguments which 
> were not passed.

It's common for wrapper functions to mirror the defaults of the wrapped 
functions and pass those along... A quick search brings up an example from 
dataclasses where sentinel values are passed as arguments to a wrapped 
callable[1].

I concede that issues with pickling such values are very unlikely. I stumbled 
upon such an issue once and it was difficult to debug, but that was a very 
unusual circumstance.

Still, it's a bit surprising that we have public facing values in stdlib 
modules which don't behave as one would expect with regard to pickling. This is 
why I created this 

It seems that I should have marked this as "enhancement" rather than the 
default of "behavior", though, since I meant this to be an improvement on the 
current situation, rather then assert the current situation is "broken".

How are you trying to start the shell? Does "shell window" mean IDLE? What 
operating system are you using? What do you mean by "it glitches"?

[issue37373] Configuration of windows event loop for libraries

[Ben Darnell]

Ben Darnell  added the comment:

> proactor-wrapper policy at IOLoop start time, which means 
> `asyncio.get_event_loop()` returns a loop with add_reader. But pyzmq doesn't

That's not what I'm doing in Tornado; I don't change the policy or the result 
of get_event_loop. Instead, I call get_event_loop (only once) and wrap its 
result in AddThreadSelectorEventLoop. This works even while the event loop is 
already running (which is not an uncommon case; there is no expectation that 
you use tornado.ioloop.IOLoop.start instead of asyncio.EventLoop.run_forever). 

This relies on the fact that I already have my own thread-local lookup function 
to retrieve the wrapped event loop; an application that used the more typical 
asyncio patterns and relied on get_event_loop would indeed have difficulty with 
this pattern.

[issue13498] os.makedirs exist_ok documentation is incorrect, as is some of the behavior

[Terry J. Reedy]

Terry J. Reedy  added the comment:

This issue was really two issues: fix doc of existing behavior; change behavior 
(which would be an enhancement).  The first has been done; the second not.  I 
think this should be closed and if anyone still proposes the second, open a new 
enhancement issue for 3.11, referencing this one, that clearly lays out the 
proposed change and rationale, given the 3.10 status quo.  (I have no opinion 
about the proposed change.)

Once someone submits a patch, we are free to change it before or after applying 
it.  But before, we give the author first crack and wait a week or so for an 
answer.

Hynek, do you still propose the change in your second patch?  If so, do you 
want to update it and make a PR?

[issue29688] Add support for Path.absolute()

[Barney Gale]

Barney Gale  added the comment:

New PR up here: https://github.com/python/cpython/pull/26153

The correspondence between `pathlib` and `os.path` is as follows:


- `Path.resolve()` is roughly `os.path.realpath()`
- `Path.absolute()` is roughly `os.path.abspath()`

Differences:

- `resolve()` always raises RuntimeError on symlink loops, whereas `realpath()` 
either raises OSError or nothing depending on *strict*.
- `absolute()` doesn't normalize the path, whereas `abspath()` does. 
Normalizing without resolving symlinks can change the meaning of the path, so 
pathlib does the better thing here.

[issue44145] hmac.update is not releasing the GIL when openssl's hmac is used

[Gregory P. Smith]

New submission from Gregory P. Smith :

This prevents parallel hmac computations.

see michaelforney's comment left on https://github.com/python/cpython/pull/20129
where the problem was introduced when adding support for using OpenSSL's HMAC 
implementations.

easy fix.  PR coming.

We don't really have a way to unittest for regressions on things like this.
