[issue43746] Weird typing annotation closure behavior

[Karthikeyan Singaravelan]

Karthikeyan Singaravelan  added the comment:

I guess this is similar to the explanation at 
https://bugs.python.org/issue36363#msg338389

> The problem in the original code is that the annotation references a global 
> name that is shadowed by a local (to the class body) name, and because of the 
> initialization, the latter takes precedence.  (To see for yourself, use the 
> dis module to disassemble the code for Spam and Spaz.)

[issue43784] starting a thread in __del__ hangs at interpreter shutdown

[Eryk Sun]

Eryk Sun  added the comment:

It's not a subprocess bug, per se. It's due to creating the stdout/stderr 
worker threads from the __del__ finalizer while the interpreter is shutting 
down. Minimal reproducer, confirmed in both Linux and Windows:

import threading

class C:
def __del__(self):
t = threading.Thread(target=print, args=('spam',), daemon=True)
t.start()

c = C()
#del c # uncomment to prevent hanging

[issue43682] Make static methods created by @staticmethod callable

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

Currently pydoc on X.sm gives:
---
sm(x, y)
A static method
---


I concur with Mark Shannon. The root problem is that Python functions and 
built-in functions have different behavior when assigned as class attribute. 
The former became an instance method, but the latter is not.

If wrap builtin open with statickmethod, the repr of open will be something 
like "staticmethod()" instead of just 
"". It is confusing. It will produce a lot of 
questions why open (and only open) is so special.

Joël Larose  added the comment:

An easy workaround would be to alias your import or to import your class 
directly.

```
from ... import losses as l

class A:
  losses: l.Losses = l.Losses()
```

or 

```
from ...losses import Losses

class A:
  losses: Losses = Losses()
```

[issue43786] slice(None) is slice(None) is False

[Nico Schlömer]

New submission from Nico Schlömer :

I stumbled upon this when dealing with NumPy arrays:
```
slice(None) is slice(None)
```
```
False
```
This came up when trying to check if a variable `a` equals `slice(None)`. The 
comparison
```
a = slice(None)
a == slice(None)
```
```
True
```
works, but doesn't return a single Boolean if a is a NumPy array, for example.

Perhaps there's another way of finding out if a variable is exactly 
`slice(None)`, but the failure of `is` seems like a bug.

[issue43787] Optimize BZ2File, GzipFile, and LZMAFile __iter__ method.

[Inada Naoki]

New submission from Inada Naoki :

__iter__ method of BZ2File, GzipFile, and LZMAFile is IOBase.__iter__. It calls 
`readline()` for each line.

Since `readline()` is defined as Python function, it is slower than C iterator. 
Adding custom __iter__ method that delegates to underlying buffer __iter__ 
makes `for line in file` 2x faster.

def __iter__(self):
self._check_can_read()
return self._buffer.__iter__()

[issue38963] multiprocessing processes seem to "bleed" user information (GID/UID/groups)

[Bartosz Kwitniewski]

Bartosz Kwitniewski  added the comment:

It works as intended - pool of 5 processes is being reused with new data:
- First, 5 processes are created as root,
- in first run of check_permission they drop their privileges to user,
- when they finish processing check_permission function, they are not killed, 
but provided with new path for processing, therefore they retain their lower 
privileges,
- when maxtasksperchild=1 is used, processes are killed after single run of 
check_permission and recreated with root permissions.

[issue43786] slice(None) is slice(None) is False

[Steven D'Aprano]

Steven D'Aprano  added the comment:

The behaviour of `is` is correct.

The `is` operator tests for object identity, not equality. The reason that 
`slice(None) is slice(None)` returns False is that the two calls to the slice 
function return two different objects.

You say that using the equals operator `==` "doesn't return a single Boolean if 
a is a NumPy array", that is a design flaw in numpy, and there is nothing we 
can do about it.

You could try something like this:

def equal(a, b):
flag = (a == b)
if isinstance(flag, bool):
return flag
else:
return all(flag)

[issue43788] Make ssl_data.h version specific

[Christian Heimes]

New submission from Christian Heimes :

_ssl_data.h contains static tables with OpenSSL error names and reasons. The 
stables are created by scrapping header files. The current approach has two 
issues:

- error codes are version dependent. OpenSSL 1.1.1 uses different codes and has 
a different set of error reasons as 3.0.0.
- parsing header files with regular expressions is err-prone.

I'm going to introduce version-specific data tables and re-write the current 
make_ssl_data.py script to use OpenSSL's crypto/err/openssl.txt and 
crypto/err/openssl.ec. The text files exist since OpenSSL 1.1.

[issue43785] Remove RLock from BZ2File

[Ma Lin]

Ma Lin  added the comment:

This change is backwards incompatible, it may break some code silently.

If someone really needs better performance, they can write a BZ2File class 
without RLock by themselves, it should be easy.

FYI, zlib module was added in 1997, bz2 module was added in 2002, lzma module 
was added in 2011. (Just curious for these years)

https://check-python-cla.herokuapp.com/ ("You can check yourself to see if the

Submitting patches for the Python documentation never used to be this hard. :-)

> I'd also prefer a Py_IsNotNone() because it's more explicit than !Py_IsNone()

I would prefer keep the C API small. I don't think that we need to duplicate 
all functions testing for something. We provide PyTuple_Check(obj) but we don't 
provide PyTuple_NotCheck(obj) for example.

IMO !Py_IsNone(obj) makes perfectly sense in Python.

Also, "x == Py_None" is more common than "x != Py_None".

[issue43753] [C API] Add Py_Is(x, y) and Py_IsNone(x) functions

[Erlend Egeberg Aasland]

Erlend Egeberg Aasland  added the comment:

> I would prefer keep the C API small.

Yes, I see the value of that as well.

I tried applying this API on an extension, and I found the code to be slightly 
less readable for the "is not" cases.

[issue37712] Exception frames from unittest.TestCase.fail dependent on nesting

[Chris Jerdonek]

Chris Jerdonek  added the comment:

> I think this is the same as issue37712.

This issue was first reported as issue24959. It would be better to close the 
newer issues as duplicates of the first one, instead of keeping all the 
duplicates open. Otherwise, the history and discussion gets fragmented across 
multiple locations.

[issue43791] OpenSSL 3.0.0: TLS 1.0 / 1.1 connections fail with TLSV1_ALERT_INTERNAL_ERROR

[Christian Heimes]

New submission from Christian Heimes :

With OpenSSL 3.0.0-alpha14 several tests for TLS 1.0 and 1.1 connections are 
failing handshake with "[SSL: TLSV1_ALERT_INTERNAL_ERROR] tlsv1 alert internal 
error". OpenSSL is configured with default security level "1". Tests are only 
passing with @SECLEVEL=0.

I think the security default callback refuses NID_sha1 and NID_sha1_md5 
SSL_SECOP_SIGALG_SUPPORTED because their security bits are lower than minimum 
of 80 bits.

STINNER Victor  added the comment:

Sadly, there is Cython release supporting Python 3.10 yet:
https://github.com/cython/cython/issues/4046

By the way, I propose two PRs to fix Cython tests on Python 3.10:
https://github.com/cython/cython/issues/4100

I suggest you waiting until there a new Cython release supporting Python 3.10.

In Fedora, we have downstream patches on Cython, we backported the Python 3.10

Is there any activity on this issue? The way Pybind11 generates accessors for

[issue43746] Weird typing annotation closure behavior

[conchylicultor]

conchylicultor  added the comment:

Yes, I know I can rename the closure, or wrap the annotation in 'quote'.

I just wanted to point this out as it felt confusing to me.
For instance, it feels inconsistent with:

```
def fn(datetime: datetime.Time):  # Works as expected
```

Or:

```
@dataclass
class A:
  datetime: datetime.Time = field(default_factory=datetime.Time.now)
```

The `datetime.Time.now` and the `datetime.Time` of the same statement refer to 
different objects.

This might be the expected behavior, but this is confusing nonetheless.

[issue43753] [C API] Add Py_Is(x, y) and Py_IsNone(x) functions

[STINNER Victor]

STINNER Victor  added the comment:

> I tried applying this API on an extension, and I found the code to be 
> slightly less readable for the "is not" cases.

FYI you can try upgrade_pythoncapi.py on your project using the following PR to 
update code to use Py_IsNone/Py_IsTrue/Py_IsFalse:
https://github.com/pythoncapi/pythoncapi_compat/pull/8

For example, use "upgrade_pythoncapi.py -o Py_Is directory/" or 
"upgrade_pythoncapi.py -o Py_Is file.c".

[issue43794] OpenSSL 3.0.0: Handle UNEXPECTED_EOF_WHILE_READING / wrap SSL_OP_IGNORE_UNEXPECTED_EOF

[Christian Heimes]

New submission from Christian Heimes :

OpenSSL 3.0.0 state machine handles unexpected EOFs more strict and requires 
peers to properly shut down connections. The old OpenSSL 1.1.1 behavior can be 
get back with SSL_OP_IGNORE_UNEXPECTED_EOF.

I propose to add the option by default until Python's ssl module has better 
ways to perform one-way shutdown of connections.

https://www.openssl.org/docs/manmaster/man3/SSL_CTX_set_options.html

> Some TLS implementations do not send the mandatory close_notify alert on 
> shutdown. If the application tries to wait for the close_notify alert but the 
> peer closes the connection without sending it, an error is generated. When 
> this option is enabled the peer does not need to send the close_notify alert 
> and a closed connection will be treated as if the close_notify alert was 
> received.

> You should only enable this option if the protocol running over TLS can 
> detect a truncation attack itself, and that the application is checking for 
> that truncation attack.

[issue40485] Provide an abstraction for a select-able Event

[Faidon Liambotis]

Faidon Liambotis  added the comment:

Thanks so much for all the work on os.eventfd(), it's exciting to see it come 
to fruition.

An eventfd variant of Event (compatible with the threading & multiprocessing 
APIs) is now as simple as:

class Event:
_ONE = (1).to_bytes(8, byteorder=sys.byteorder)

def __init__(self):
self._event_fd = os.eventfd(0, os.EFD_NONBLOCK)
self._selector = selectors.DefaultSelector()
self._selector.register(self._event_fd, selectors.EVENT_READ)

def is_set(self):
return self.wait(timeout=0)

def set(self):
try:
os.write(self._event_fd, self._ONE)
except BlockingIOError:
pass

def clear(self):
try:
os.read(self._event_fd, 8)
except BlockingIOError:
pass

def wait(self, timeout=None):
return bool(self._selector.select(timeout=timeout))

def fileno(self):
return self._event_fd

Given this now has a fileno() method, it is now possible to wait for the event 
as part of a broader selector, among other events (e.g. a file or socket 
becoming available to read or write).

I don't know where (or how) such a variant would fit into stdlib. It's simpler 
and more lightweight (less fds) than both threading's and multiprocessing's, 
and could be used from both threads and processes. I'd love some guidance here. 
(If a maintainer or anyone else reading this wants to use the above code in a 
PR, feel free -- no copyright claimed or expected for this trivial piece of 
code above)

[issue43796] "install" package on PyPI

[Jared Ondricek]

New submission from Jared Ondricek :

I recently accidentally typed "pip install pip install " and it installed a package called "install" that has 1 star on GitHub. 
It is also in use by 2.3k repositories according to the GitHub dependency graph 
view. I don't think it's malicious, but it does seem a bit sketchy. I just know 
this sort of thing has been in the news lately, and maybe this is that sort of 
thing that ought to be looked at by someone smarter than me about security 
stuff.

The way Perl deals with this specific issue is by using a specific dummy module 
so no one can do this on accident.

Is this worth the time to discuss? Or am I just being paranoid about a third 
party library called install?

PyPI entry: https://pypi.org/project/install/
GitHub page: https://github.com/eugenekolo/pip-install
GitHub projects that depend on it:

[issue43737] Documentation of modulo operator should document behaviour clearly when second operator is negative

[Anthony Flury]

Anthony Flury  added the comment:

I fundamentally disagree with closing this - I know that this and many other 
'quirks' catch beginners out, and the tutorial is what they use to learn.They 
don't look in the reference document - it is too dense in BNF definitions which 
turns a lot of people off from any other useful information - When I was 
researching this issue I didn't even think to look in the reference section.

Looking in the library section for information about the built-in types is also 
non-obvious to beginners. 

If the tutorial doesn't contain the detail, and doesn't link to the detail then 
beginners are left entirely puzzled by the behavior.

Given how difficult it is to search the documentation if you don't know exactly 
what you are looking for, then how beginners would know to look at the FAQ is 
beyond me. Having communicated with a number of beginners on a number of issues 
they had no idea that the FAQ even existed.

The change didn't 'bury the tutorial in detail' - it added once sentence which 
linked to the FAQ. In fact all the change did was expand the FAQ entry by a few 
lines and link to the FAQ from the three places that are relevant.

I think this is a small change and it should be the start of making the 
tutorial beginner friendly.

[issue38820] Make Python compatible with OpenSSL 3.0.0

[Christian Heimes]

Christian Heimes  added the comment:

Miro,

I have pushed several fixes for OpenSSL 3.0.0

* bpo-43788 addresses wrong library and error reason codes (e.g. KRB5_S_TKT_NYV)
* bpo-43789 fixes an issue with exception state in password callbacks 
(_PyEval_EvalFrameDefault returned a result with an exception set)
* bpo-43791 disables TLS 1.0 and 1.1 testing with OpenSSL 3.0.0. I'll have to 
talk to upstream and figure out a better solution.
* bpo-43794 adds OP_IGNORE_UNEXPECTED_EOF and sets it by default. This makes 
the code behave like OpenSSL 1.1.0 and 1.0.2.

I'll look into the other issues next week.
