[issue46080] argparse.BooleanOptionalAction with default=argparse.SUPPRESS and help specified crashes

[Felix Fontein]

New submission from Felix Fontein :

When argparse.BooleanOptionalAction is used with default=argparse.SUPPRESS and 
help is specified, trying to display --help results in a crash.

Reproducer:

import argparse
parser = argparse.ArgumentParser()
parser.add_argument('--test', action=argparse.BooleanOptionalAction, 
default=argparse.SUPPRESS, help='Foo')
parser.parse_args()

Result when running 'python t.py --help':

Traceback (most recent call last):

  File "/usr/lib/python3.10/argparse.py", line 627, in _expand_help
return self._get_help_string(action) % params
KeyError: 'default'

The problem is that in 
https://github.com/python/cpython/blob/f54fee7f37563fbd569596cf94aad023ac6c3179/Lib/argparse.py#L879,
 default isn't tested for SUPPRESS as well. I've prepared a patch to fix that 
and will push it to GitHub soon.

(I've experienced the crash with Python 3.9 and 3.10; the test I've created 
also crashes for the current main branch, so I guess that means that Python 
3.11 is also affected. I haven't tested older Python versions before 3.9.)

```

Found it when I tried to unparse previously parsed:
```py
class C:
i: int
```

Found in reality when trying to parse then emit:
- 
https://github.com/tensorflow/tensorflow/blob/ba146843/tensorflow/compiler/xla/python/xla_client.py#L402-L413


Which is creating this:
```
ast.Assign(targets=[ast.Name(id="interior_padding")],
   type_comment="int",
   value=None)
```

(one thing my library does is convert betwixt `ast.Assign` and `ast.AnnAssign`… 
later I'll be doing more interesting variable type tracing to generate big 
`typing.Union` of all possible types each variable may have… but if it finds 
`None` then it will infer `typing.Optional`.)

Here is my `ast.NodeTransformer` override for `visit_AnnAssign`: 
https://github.com/offscale/cdd-python/blob/968507e/cdd/doctrans_utils.py#L111-L131

Is there some way of rewriting an `ast.AnnAssign` to `ast.Assign` without 
losing type information?

[issue46077] Include sha256 hashes of release downloads in announcement communications

[Gregory P. Smith]

New submission from Gregory P. Smith :

The announcement email list 
(https://mail.python.org/archives/list/python-announce-l...@python.org/) and 
other places we make announcements beyond just the release pages like 
https://www.python.org/downloads/release/python-3101/ should include a list of 
sha256 hashes of the release binaries in the announcement text.

This serves as an alternative confirmation that nothing has changed as such 
announcements are widely distributed and archived by independent parties and 
individuals and can thus convey a level of trust that a hash listed on the 
downloads page cannot (where an attacker would simply modify both).

Yes there is a gpg signature on the downloads. I encourage people to use that.  
But this provides an alternate distributed mechanism to verify that nothing has 
changed at all since the release announcement.  Something a gpg signature 
cannot fully do (consider this protection against the possibility of new signed 
binary being put into its place by a compromised key/signer/builder/RM before 
anyone happens to notice and poke around).

A simple table of:

filename.tar.gz | sha256 hash
filename.msi | sha256 hash
filename.dmg | sha256 hash
...

At the end of the announcement email/post would suffice.

Less of an issue on source packages as those can be verified against the git 
repo. But it's nice for people to know if binaries change without an 
announcement and explanation and is easy for us to provide.

Bonus points if the release announcement email body itself is signed (if that 
is even feasible per our release signing GPG key management).

[issue46056] Cannot use virtual environment on Windows 10 in corporate security settings

[Gregory P. Smith]

Gregory P. Smith  added the comment:

While the discussion is interesting for some who are trying to work around 
security policy mechanisms, we can't control what policies people enforce upon 
themselves that make their machines useless for software development.  Marking 
as not a bug.

The normal thing to do is to obtain an exemption to policies from the corporate 
security org managing your machine(s) because you have a business need for it.

If you have specific implementation changes that would make life easier, file 
specific issues for those to be addressed.  (ex: PEP 582 is pretty specific - 
and there is a package manager https://pdm.fming.dev/ that supports it)

[issue46076] Document using __slots__ to provide per-attribute docstrings

[Alex Waygood]

New submission from Alex Waygood :

The ability to add docstrings for individual attributes, by using a dictionary 
for __slots__ was added in Issue36326. This is a fantastic feature, and 
deserves better documentation. It appears to currently only be documented in 
the "What's New" entry for Python 3.8: 
https://docs.python.org/3/whatsnew/3.8.html#inspect.

Moreover, the data model documentation currently states the following regarding 
using a mapping to specify __slots__:

"""
Any non-string iterable may be assigned to __slots__. Mappings may also be 
used; however, in the future, special meaning may be assigned to the values 
corresponding to each key.
"""

This is arguably now incorrect. A special meaning has been assigned to the 
values corresponding to each key: the values can be used for per-attribute 
docstrings.

[issue29699] shutil.rmtree should not fail with FileNotFoundError (race condition)

[coroa]

coroa  added the comment:

Just realised that the "race condition" is triggered consistently on Mac OSX 
machines working on non-Mac filesystems, where they store extended attributes 
like last access time in meta files with a `._` prefix. These files are listed 
by `os.scandir` after their original files and are removed, as soon as the 
original file is unlinked.

Ie. a test.txt, ._test.txt pair will always raise FileNotFoundError for 
._test.txt since the file system driver itself already removed it when the 
unlink on test.txt was executed.

Refer also to https://stackoverflow.com/a/70355470/2873952.

Current status seems to be:
1. https://bugs.python.org/issue29699 and https://bugs.python.org/issue37260 
are duplicates.
2. https://github.com/python/cpython/pull/13580 linked from here has been 
closed due to lack of unit tests (but with the possibility to re-open after 
providing those)
3. https://github.com/python/cpython/pull/14064 is still open and seems to be 
mostly the same patch, does have unit tests and awaiting a second review.

What is the next step?

[issue46028] 3.11.0a3: under tox, sys._base_executable is wrong

[Steve Dower]

Steve Dower  added the comment:

Does the first venv's 'python' link to python3[.11]? If so, maybe 
_base_executable should be based on real_executable's filename rather than 
executable (that is, *after* resolving symlinks rather than before).

I don't *think* that will cause any issues, and it shouldn't be any more 
expensive to compute. Only has to change for when a pyvenv.cfg is detected I 
think.

[issue46073] ast.unparse produces: 'FunctionDef' object has no attribute 'lineno' for valid module

[Nikita Sobolev]

Nikita Sobolev  added the comment:

Or, maybe this is a correct thing to do. Consider this case. Let's say we now 
check that `node` has `lineno` and exclude ones that don't.

Then, we write this test (in `Lib/test/test_unparse`):

```
def test_unparse_nodes_without_lineno(self):
# https://bugs.python.org/issue46073
def create_module(ignores):
return ast.Module(
body=[
ast.FunctionDef(
name="items_needed",
args=ast.arguments(
posonlyargs=[], args=[],
kwonlyargs=[], kw_defaults=[], defaults=[],
),
body=[ast.Pass()], decorator_list=[],
),
],
type_ignores=ignores,
)

ast1 = create_module([])
self.assertASTEqual(ast1, ast.parse(ast.unparse(ast1)))

ast2 = create_module([ast.TypeIgnore(lineno=1, tag='')])
# This fill fail without `ast2 = ast.fix_missing_locations(ast2)`
self.assertASTEqual(ast2, ast.parse(ast.unparse(ast2), 
type_comments=True))
```

In this case the second `assert` will fail, because the resulting codes would 
be different:

```
# "original"
def items_needed():  # type: ignore
pass

# unparsed
def items_needed():
pass
```

So, basically users will get different code. Which is not a good thing.

So, maybe raising an error that some `node` does not have `lineno` is good 
after all?

[issue46073] ast.unparse produces: 'FunctionDef' object has no attribute 'lineno' for valid module

[Brian Carlson]

Brian Carlson  added the comment:

I don't think passing `lineno` and `column` is preferred. It makes code 
generation harder because `lineno` and `column` are hard to know ahead of when 
code is being unparsed.

[Brian Carlson]

Brian Carlson  added the comment:

The second solution seems more optimal, in my opinion. I monkey patched the 
function like this in my own code:
```
def get_type_comment(self, node):
comment = self._type_ignores.get(node.lineno) if hasattr(node, "lineno") 
else node.type_comment
if comment is not None:
return f" # type: {comment}"
```

Thanks!

[issue46075] CookieJar.extract_cookies doesn't process cookies form local domains when domain is explicitly set in header

[Nick]

New submission from Nick :

Apparently, CookieJar.extract_cookies doesn't process cookies form local 
domains which explicitly set domain in Set-Cookie header. That means that 
headers with domain specified, like "Set-Cookie: foo=baz; Domain=localhost;", 
are ignored. As far as I can tell, this might be actually part of the standard: 
https://stackoverflow.com/questions/1134290/cookies-on-localhost-with-explicit-domain/32210291#32210291
 . However, it looks like other HTTP clients, including modern versions of both 
Chrome and Firefox do accept cookies from localhost with explicit 
domain=localhost, and this change doesn't appear to break existing software in 
any way. (simple POC to test behavior in browsers: 
https://gist.github.com/keddad/e2ce034f68b77e59077cdb1e887fa4a1). Maybe it 
would be best to also allow this behavior in Python?

[issue45339] concurrent.future.ThreadPoolExecutor should parameterize class used for threads

[Sergei Maertens]

Sergei Maertens  added the comment:

I was looking for some way to be able to add a thread finalizer, a piece of 
code to be called when the thread pool shuts down and all threads need cleaning 
up. Glad I came across this issue, since the example of using a Thread subclass 
with a custom run (wrapped in a context manager) would fill my needs completely.

> What are examples of your some_important_context()? Is it important to call 
> some code before destroying the thread?

I currently have a use case with a web-framework that has persistent DB 
connections - i.e. they span multiple HTTP requests. This also applies in the 
context of running a command-line script with said framework where database 
connections are opened.

We are calling external APIs (IO heavy), so using a ThreadPoolExecutor makes 
sense. However, since those "DB connection pools" are thread locals, we need to 
ensure that database connections are closed again to not leak resources.

The current workaround is to submit a job/function to the pool and have it 
close the database connections, which adds overhead since database connections 
are now opened and closed within the same thread that could have been re-used.

Using a context manager, we would be able to wrap the `super().run(...)` and 
close the database connections when the thread exits (succesfully or because of 
an Exception, even). This comes very close to having an `atexit` for individual 
threads.

Furthermore I like the idea of being able to provide the class as a context 
manager kwarg, but would also not be opposed to a class property specifying the 
Thread class to use - both would greatly enhance composability and are a 
cleaner solution than adding a finalizer option (similar to the `initializer` 
kwarg)

[issue46073] ast.unparse produces: 'FunctionDef' object has no attribute 'lineno' for valid module

[Nikita Sobolev]

Nikita Sobolev  added the comment:

Looks like this little patch can solve this problem:

```
   def unparse(ast_obj):
   unparser = _Unparser()
---return unparser.visit(ast_obj)
+++return unparser.visit(fix_missing_locations(ast_obj))
```

But, I am not sure we should call this helper here.

Another approach is to refactor `get_type_comment` function into something like 
this:

```
def get_type_comment(self, node):
comment = None
if hasattr(node, 'lineno'):
comment = self._type_ignores.get(node.lineno)
comment = comment or node.type_comment
if comment is not None:
return f" # type: {comment}"
```

I feel like this is more suitable for this case. Even `ast.pyi` has this line:

```
# TODO: Not all nodes have all of the following attributes
lineno: int
col_offset: int
```

So, I am going to propose a PR with the second option. Please, send your 
feedback!

[issue45292] Implement PEP 654: Exception Groups

[Irit Katriel]

Irit Katriel  added the comment:

The PR adds two new opcodes. Let's start with the simpler of the two - 
JUMP_IF_NOT_EG_MATCH.   This is the exception-group variation on 
JUMP_IF_NOT_EXC_MATCH.

JUMP_IF_NOT_EXC_MATCH checks for a match by checking if the exception is of the 
given type. The result is boolean.

JUMP_IF_NOT_EG_MATCH checks for a matching by calling .split() on the exception 
group. The result is two exception groups (the matching part and the 
non-matching part).

Can we do this without a new opcode?

[issue45292] Implement PEP 654: Exception Groups

[Mark Shannon]

Mark Shannon  added the comment:

PR 29581 resulted in a 1% slowdown, which is not terrible, but code not using 
except* should not be slowed down at all.

IMO, the way to avoid the slowdown is to implement except* using the existing 
instruction set (perhaps with a few minor additions)

We already implement try-finally, named except blocks and with statements 
without any complex bytecodes (except perhaps WITH_EXCEPT_START).

These used to involve a lot of state and more complex bytecodes. So it is 
possible to make these simplifications,
but it does take work.


There are a number of techniques we can use:

If any state is needed, push it to the stack as we do with `ctx.__exit__` in 
the with statement, and when pushing f_lasti in exception handlers.
Duplicate code paths when the semantics differ in different cases, as we do for 
finally blocks.
If anything is too complex to handle on the stack, put it in a temporary 
variable.
Be liberal in your use of virtual try-excepts (SETUP_FINALLY, POP_FINALLY 
pairs), as zero-cost exception handling should keep the cost down.


It may be too late for this advice, but if I were writing the `except*` 
implementation from scratch, I would:

1. Sketch out the pseudo Python that a try-except* would map to. This is a good 
opportunity to discover any design bugs that might result in undesirable 
behavior for corner cases.

2. Implement the translation in the compiler, not worrying about any redundancy 
or inefficiency, just correctness.

3. Look to improve the above, either in the compiler front-end, or by replacing 
inefficient code patterns in the back-end. Handling the optimization in the 
backend has the advantage that other code might benefit as well.

[issue18467] argparse - problematic 'default' behavior

[Matěj Týč]

Matěj Týč  added the comment:

Thanks for reaching out. I have no idea whether it helped me or not, sorry for 
not replying back in a timely manner :-(

I think that the feature request/bugreport originates from bad coding 
practices, when I wanted argparse to perform something more than just plain 
parsing of arguments into a data structure.

Nowadays I would tell myself to solve it by introducing a layer between 
argparse and the rest of the code without putting additional pressure on 
argparse.

[issue46074] deepfreeze should rehash all strings upon reset

[Guido van Rossum]

New submission from Guido van Rossum :

In https://github.com/python/cpython/pull/30096#discussion_r768802144 it is 
pointed out that the hash seed can be changed if the interpreter is reset.

To guard against this we need to force (re)calculation of all hash seeds in the 
generated code when the corresponding code object is retrieved. This can be 
done by adding extra code to the `_Py_get__toplevel()` functions. 
(Strings that are shared between code objects will have to be rehashed 
repeatedly -- no big deal.)

[issue46072] Unify handling of stats in the CPython VM

[Mark Shannon]

New submission from Mark Shannon :

By "stats" I mean the internal numbers gathered by the VM for performance and 
debugging. This has nothing to do with any statistics module.

Currently various parts of the VM gather stats: the GC, dicts, the bytecode 
interpreter, type lookup cache, etc.

These stats have various compile time flags to turn them on and off. They have 
differing ways to display the stats, and no unified way to gather stats across 
different runs.

For the specialization stats we dump stats, which we can parse to collate stats 
across runs.

We should:
1. Add a --with-pystats config flag (like with-pydebug) to turn on stat 
gathering at build time.
2. Convert the other stats to the format used by the specialization stats, so 
all stats can be parsed and collated.

[issue46046] I/O bound threads got to no chance to run with small CPU bound threads with new GIL

[Ken Jin]

Ken Jin  added the comment:

Hi,

Thank you for your interest in Python, and especially the GIL. David Beazley 
opened an issue for his PyCon 2010 GIL talk at 
https://bugs.python.org/issue7946. You can discuss more on that issue (I 
suggest first reading through it, there's a really long history behind the GIL).

I'm closing this issue as a duplicate, as discussion should be redirected to 
the abovementioned issue7946 instead.

[issue46071] Graphlib documentation

[David Mc Dougall]

New submission from David Mc Dougall :

The documentation for graphlib encourages users to represent their graphs in a 
awkward format.

Graphs are currently represented using dictionaries of nodes, for example:
graph["end_node"] = ["start_node"]

And this is unintuitive because you can't use the graph traverse edges in their 
forward direction.
If you look up a node in the graph, you get all of the nodes that point to the 
key,
as opposed to all of the nodes that the key points to.

The solution is to rewrite the documentation such that all of the edge 
directions are reversed.
The final topologically sorted list will be in the "opposite" direction as a 
consequence.

This will cause no functional changes.

[issue46056] Cannot use virtual environment on Windows 10 in corporate security settings

[wolfgang kuehn]

wolfgang kuehn  added the comment:

I can confirm that setting __PYVENV_LAUNCHER__ to ANY path with prefix  
./venv/Scripts/ does indeed mark the python session as being a virtual 
environment, no special permissions needed.

However, you will have no tooling support whatsoever (e.g. PyCharms Package 
Mngt) because __PYVENV_LAUNCHER__ is, after all, non-standard.

[issue45383] PyType_FromSpec API fails to use metaclass of bases

[Petr Viktorin]

Petr Viktorin  added the comment:

I haven't forgotten this issue, but when I get to it it always leads to a 
rabbit hole. Sometimes just chasing refleaks, but there are deeper issues as 
well.

AFAICS, there's no way to call metatype.tp_new for such a class. I guess the 
safest option is to fail when the metaclass has a custom tp_new -- because that 
means the metaclass is requesting that it wants to allocate/initialize its 
types itself.

We can call metatype.tp_init, and probably should. And __init_subclass__ too, I 
suppose.

But at that point, this is duplicating a lot of existing functionality, and I'm 
starting to wonder if this wouldn't all be better with calling the metaclass 
instead.
What's missing?
- basicsize/itemsize could be allowed with __basicsize__/__itemsize__ in the 
dict.
- flags: we could add mechanisms to set individual flags after the type is 
created, as needed.
- slots can usually be applied after the class is created; maybe there should 
be a public function for this.
- members could theoretically be copied to individual descriptors; there 
doesn't seem much need for keeping tp_members around.

Does that seem like a more reasonable direction to explore?

[issue46028] 3.11.0a3: under tox, sys._base_executable is wrong

[Steve Dower]

Steve Dower  added the comment:

Or possibly that error is coming from the attempt to copy it? And since 
both executable and base_executable don't have the 3/3.x suffix, the 
copy is failing because the "real" binary does have the suffix.

This could be corrected in getpath.py with a platform-specific quirk 
that searches for suffixed binaries for base_executable, but for 
performance reasons I think we'd prefer to have that check in venv so 
that it doesn't impact every single launch of CPython.

The actual binary could also be added to pyvenv.cfg as another value - 
parsing that out in getpath.py is now considerably easier for someone to 
add than it used to be.

> Error: [Errno 2] No such file or directory:

I assume /private/tmp/bpo-46028/311-nested/bin/python3.11 exists though? 
Probably that's the issue here - I don't know how else to get the real 
executable *name* other than copying from argv[0], and it isn't supposed 
to be necessary.

You also have v311/bin/python3.11, right? If you use that one, does it 
work? I'm trying to narrow down where the base executable is actually 
being launched and why.

[issue46070] broken subinterpreters

[graysky]

New submission from graysky :

Seems as though cpython is broken when working with subinterpreters. The 
problematic change could be (d0d29655ff) affecting import.c.[1] Reverting this 
commit and rebuilding python fixes the issues on my system with some scripts 
that import sqlite, for example, the Kodi plugin YouTube[2] and the IMDB 
Trailers plugin. Others have reported similar breakage with other python 
code[3].

Example output when the bug manifests:

ERROR : Traceback (most recent call last):
ERROR :   File "/usr/lib/python3.10/sqlite3/dbapi2.py", line 83, in
