[issue47040] Remove invalid versionchanged in doc

[Ma Lin]

Ma Lin  added the comment:

`binascii.crc32` doc also has this invalid document:
doc: https://docs.python.org/3/library/binascii.html#binascii.crc32
3.0.0 code: https://github.com/python/cpython/blob/v3.0/Modules/binascii.c#L1035

In addition, `binascii.crc32` has an `USE_ZLIB_CRC32` code path, but it's buggy.
The length of zlib `crc32()` function is `unsigned int`, so if use 
`USE_ZLIB_CRC32` code path and the data > 4GiB, the result is wrong.
Should we remove `USE_ZLIB_CRC32` code path in `binascii.c`, or fix it?

`USE_ZLIB_CRC32` code path in binascii.c (bug code): 
https://github.com/python/cpython/blob/v3.11.0a6/Modules/binascii.c#L756-L767
crc32 in zlibmodule.c, it uses an UINT_MAX sliding window (right code):
 https://github.com/python/cpython/blob/v3.11.0a6/Modules/zlibmodule.c#L1436

Requests is a 3rd party package and not part of the standard library.

There is a problem with the HTTP server at http://183.246.199.100:8321. It is 
sending a HTTP redirect with the port number duplicated: ":8321:8321". Please

[issue46996] Drop support of Tcl/Tk older than 8.5.12

[Ronald Oussoren]

Ronald Oussoren  added the comment:

One consideration is support for older LTS distributions of Linux, RHEL/Centos 
7 appears to ship with Tcl/Tk 8.5. 

The system install of Tcl/Tk on macOS is also 8.5, but that variant has too 
many bugs to try to support it.

[issue46996] Drop support of Tcl/Tk older than 8.5.12

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

8.5.12 will be 10 years old at the time of releasing 3.11.

We can relax the requirements for 8.5.x, so the code can be build with older 
versions, but some tests will fail because we removed workarounds for 
differences in behavior in older versions from tests.

The LTS distributions can also provide their own patches which relax the 
requirements.

[issue47042] Fix test_html_doc in test_pydoc

[Serhiy Storchaka]

New submission from Serhiy Storchaka :

Due to missed splitlines() in test_pydoc the HTML output was not tested 
correctly. Instead of testing that the actual output contains every *line* from 
the expected output it tested that the actual output contains every *character* 
from the expected output. The test would pass with any actual output which 
contains all Latin letters and some punctuation.

The following PR fixes this bug and makes the test even more strict. Now it 
tests that the actual output contains the same lines as the expected output, in 
the same order, ignoring indentation and empty lines.

[issue47043] Argparse can't parse subparsers with parse_known_args

[rive_n]

New submission from rive_n :

Let's say we have default parser configuration:
https://docs.python.org/3/library/argparse.html#other-utilities

Like this one:

```python3
import argparse

parser = argparse.ArgumentParser(prog='PROG')
parser.add_argument('--foo', action='store_true', help='foo help')
subparsers = parser.add_subparsers(help='sub-command help')

# create the parser for the "a" command
parser_a = subparsers.add_parser('a', help='a help')
parser_a.add_argument('-a', help='bar help')

# create the parser for the "b" command
parser_b = subparsers.add_parser('b', help='b help')
parser_b.add_argument('-b', help='baz help')

```

So i want to parse all subparsers arguments. For this purpose i could use 
`parse_known_args` method. 

But for some reason there is no way to get all of current args specified via 
command prompt or via list:
`print(parser.parse_known_args(['a', '-a', '12', 'b', '-b', '32']))` - will not 
print 'a' and 'b' data. It will only contain first valid argument; 

This is pretty strange behavior. Why i can't just get all of actions 
(subparsers) ?

This is pretty strange behavior. Why i can't just get all of actions 
(subparsers) ? 

--- 

I've found a solutions:
1. Easy way (and most stupid):

```python3
args, unk_args = (parser.parse_known_args(['a', '-a', '12', 'b', '-b', '32']))
args, unk_args = (parser.parse_known_args(unk_args))
```

Simple recursive calls on `unk_args`

2. Hard way -> sources fork (or just fix this, lul!)

`parse_know_args` -> 1799-1807 lines:

```python3
try:
namespace, args = self._parse_known_args(args, namespace)
if hasattr(namespace, _UNRECOGNIZED_ARGS_ATTR):
args.extend(getattr(namespace, _UNRECOGNIZED_ARGS_ATTR))
delattr(namespace, _UNRECOGNIZED_ARGS_ATTR)
return namespace, args
except ArgumentError:
err = _sys.exc_info()[1]
self.error(str(err))
```

There is only 1 call to `self._parse_known_args` instead of amount of current 
subparsers.

[issue43019] wait_for(to_thread)) does not work as expected. Extra documentation or fix needed.

[Andrew Svetlov]

Andrew Svetlov  added the comment:

Threads are not interruptable in Python.
The same for concurrent.future executor.
asyncio and `wait_for` is not special.

I'm not sure should we document it and *if* yes -- where should we do it?

Adding a note to every function could be cumbersome.

[issue46382] dataclass(slots=True) does not account for slots in base classes

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

Sorry, the previous message was written via a phone because of blackout, so the 
formatting is a tine bit messy.

__slotnames__ is set in copyreg._slotnames(). If you want to keep a list of all 
slots you should save it in __slotnames__, either using copyreg._slotnames() 
directly or by duplicating its code.

But as for the original issue, I do not think that the current behavior is 
incorrect. At least it is consistent with the behavior of regular classes.

[issue46996] Drop support of Tcl/Tk older than 8.5.12

[Terry J. Reedy]

Terry J. Reedy  added the comment:

Ronald: According to a page (which I cannot find, E. Paine should know) Centos 
7 has the oldest tcl among current *nix distributions.  
https://centos.pkgs.org/7/centos-x86_64/tcl-8.5.13-8.el7.x86_64.rpm.html
says it is 8.5.13, which is what I remember from the comparison page.

Serhiy: IDLE has required TkVersion >= 8.5 for some years (currently top of 
pyshell.py).  Does the _tkinter.c line
  #error "Tk older than 8.5.12 not supported"
translate into an ImportError (which is already caught).  I never worried about 
someone trying to import 8.3 or before, but Apple's 8.5.9 is possible.

Is there any reason that IDLE might someday require 8.6 before tkinter does?

Python2. 
Configuration :
Mac osx Lion 10.7.5.
Python2 : 2.7.18
Compiler : clang (Xcode).
Tcl/Tk : 8.6.12.
If I succeed, log files will be enclosed hereby.
Thank you.

[issue46996] Drop support of Tcl/Tk older than 8.5.12

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

After PR 31839 has been merged you cannot build the _tkinter module with Tcl/Tk 
older than 8.5.12. If you will still try to run IDLE on such incomplete build, 
an import error during importing tkinter will be translated to IDLE error:

$ ./python -m idlelib
** IDLE can't import Tkinter.
Your Python may not be configured for Tk. **

IDLE might someday require 8.6 if it start using some 8.6 features 
non-optionally.

[issue47045] Remove the RESUME instruction

[Mark Shannon]

New submission from Mark Shannon :

The RESUME instruction was added to make resumption points explicit in the 
bytecode. This makes it easier to implement tracing, quickening, and interrupt 
checks as there is an explicit place to perform these checks.

Unfortunately, it also has considerable overhead. So we should remove it.
To do that, we need to:
1. Remove f_state from the InterpreterFrame so we don't need to update it.
2 .Quicken automatically in the adaptive instructions.
3. Check the evalbreaker when resuming a frame in the interpreter.
4. Add some metadata to the code object, so that we know when to fire "call" 
events when tracing.

[issue47046] Add `f_state` attribute to FrameObjects.

[Mark Shannon]

New submission from Mark Shannon :

When tracing, the event supplied is insufficient to determine what is actually 
happening.

E.g. A "call" event could be a call to a function or resuming a generator or 
coroutine.

Adding a state field to the FrameObject would allow these cases to be 
disambiguated without having to make dubious deductions from `f_lasti` or other 
frame attributes.

The proposed states would be:

FRAME_CREATED# Frame created, but not executed at all
FRAME_SUSPENDED  # Frame suspended after yield or yield from
FRAME_EXECUTING  # Frame is executed normally
FRAME_COMPLETED  # Frame has completed 
FRAME_CLEARED# Frame has been cleared


Ned, any other states that you might need to know about?

[issue47047] smtplib: allow custom policy or use msg.policy in send_message

[Mikael Koli]

New submission from Mikael Koli :

The method smtplib.SMTP.send_message does not use the message's Policy if all 
of the from_addrs or to_addrs are not international. See: 
https://github.com/python/cpython/blob/v3.10.3/Lib/smtplib.py#L983 (unchanged 
in current main). The email.generator.BytesGenerator does not capture the 
email's policy as it was not passed to its init.

This has at least one notable setback: you cannot set the mangle_from to False 
meaning that the method will always turn "From ..." to ">From ..." in the plain 
text part (though often that is desirable). This is especially confusing as 
email library has the mangle_from as False by default for EmailMessages but 
smtplib.SMTP's send_message does not respect this by default.

The smtplib.SMTP.send_message has a mention about this in the docstring thus 
not entirely sure if intentional:

... Otherwise the generator is called without modifying the
policy.


If we changed this line: 
https://github.com/python/cpython/blob/v3.10.3/Lib/smtplib.py#L983

from this:
g = email.generator.BytesGenerator(bytesmsg)

to this:
g = email.generator.BytesGenerator(bytesmsg, policy=msg.policy.clone()

smptlib's tests are passed but I suspect it's not that simple. The docstring 
mention indicates this is at some level intentional and I think the mangle_from 
needs to remain True as otherwise, it may cause security problems in existing 
code. Another option perhaps could be that the policy could be passed with the 
send_message and that is used if not None or we could have argument 
"msg_policy=False" that if True, the message's policy is used.

One could also think that this could be overcome by subclassing the SMTP. 
However, the logic is such deep in that it is not convenient.

So in short, the options I thought of:
- Have an argument "policy" in send_message to force usage of your own policy 
(safe option)
- Have an argument "msg_policy" (name debatable) in send_message and if True, 
the message's policy is always used (safe option)
- Use the message's policy always (unsafe, possibly breaking and causing 
security issues in existing code)

[issue42838] Wait for cleanup coroutines before event loop is closed.

[Andrew Svetlov]

Andrew Svetlov  added the comment:

asyncio.run() present since Python 3.7
After the main coroutine finish, it cancels all background tasks and waits for 
their termination.

Background tasks can use old good `try/finally` for resources cleanup.
An additional API is not required IMHO.

[issue46965] Enable informing callee it's awaited via vector call flag

[Dino Viehland]

Dino Viehland  added the comment:

Doh, sorry about that link, this one goes to a specific commit: 
https://github.com/facebookincubator/cinder/blob/6863212ada4b569c15cd95c4e7a838f254c8ccfb/Python/ceval.c#L6642

I do think a new opcode is a good way to go, and that could just be emitted by 
the compiler when it recognizes the pattern.  I think we mainly avoided that 
because we had some issues around performance testing when we updated the byte 
code version and the peek was negligible, but with improved call performance in 
3.11 that may not be the case anymore.

It's probably possible to keep most of gather in Python if necessary, there'd 
still need to be a C wrapper which could flow the wrapper in and the wait 
handle creation would need to be possible from Python (which slightly scares 
me).  There's probably also a perf win from the C implementation - I'll see if 
@v2m has any data on that.

[issue46996] Drop support of Tcl/Tk older than 8.5.12

[Terry J. Reedy]

Terry J. Reedy  added the comment:

tk release availability is a bit confusing.
  https://wiki.tcl-lang.org/page/Changes+in+Tcl%2FTk+8%2E6
appears to lists things 'new' in 3.6.1, but that seems to mean new since 8.5.1, 
as it includes thing introduced in 8.5.n, where n > 1. For instance, ttk 
spinbox is listed in this doc, but was available in 8.5.9, so is in 8.5.12+ and 
can be used without an 8.6 requirement.

Similarly,
  https://www.tcl.tk/man/tcl8.5/TkCmd/ttk_treeview.html
the 8.5.19 doc for the widget, shows the 'new in 8.6' treeview tag commands.  I 
suspect that they were present in 8.5.13.  Is there a specific 8.5.12 doc 
available?  I searched and tried adding '.12' in the url above and both failed. 
 Buildbots without _tkinter don't help either.

[issue47049] Incorrect shutil.copytree() behaviour with symlinks

[Zoltan Vajda]

New submission from Zoltan Vajda :

shutil.copytree incorrectly does not copy symlink contents if called
with symlink=False and ignore_dangling_symlinks=True.

The wrong behaviour can be reproduced like this:

$ tree
.
└── a
├── a.txt
└── b
└── a.txt -> ../a.txt

$ python3 -c "import shutil;shutil.copytree('a/b', 'c', symlinks=False, 
ignore_dangling_symlinks=True)"

As a result directoy c will be created but it will remain empty.
Expected result is a file c/a.txt with the contents of a/b/a.txt.

[issue47050] Cannot install Python 3.10.3 on Windows

[Alex Waygood]

New submission from Alex Waygood :

I have tried several times now to upgrade to Python 3.10.3 using the 64-bit 
installer for Windows at https://www.python.org/downloads/release/python-3103/. 
Each time, I encounter an error message stating that "The feature you are 
trying to use is on a network resource that is unavailable". Further error 
messages include statements that "The older version of Python 3.10.3 Test Suite 
(64-bit) cannot be removed", and finally, "0x80070643 - Fatal error during 
installation".

Screenshots of the full error messages are attached.

Hardware details:
- Microsoft Windows 10 Home, Version 10.0.19043 Build 19043
- A x64-based PC
- An HP Pavilion Notebook laptop
- Processor AMD A8-7410 APU

Does anybody have any idea what might be going wrong?

I initially tried installing Python 3.10.3 with 3.10.2 still installed, but 
have now uninstalled Python 3.10.2 from my machine. It has made no difference.

[Steve Dower]

Steve Dower  added the comment:

Looks like you may have "cleaned up" your package cache at some point, which 
means you can't uninstall the old version anymore.

Try getting the 3.10.2 installer and running it directly. If it's the right 
one, you'll get Modify/Repair/Uninstall options, and those should work. (At 
worst, "Repair" will work and then it should be uninstallable.)

I think it depends on whether we want to say the standard/included/built-in 
import mechanisms don't support byte paths, or byte paths are entirely not 
supported even for 3rd-party code? I definitely think we should at least do the 
former, but I'm hesitant to close the door for those that need it by doing the 
latter.

[issue47023] re.sub shows key error on regex escape chars provided in repl param

[Raymond Hettinger]

Raymond Hettinger  added the comment:

There seem to be a number of escaping problems in the OP's example.

Is this what was intended?

>>> re.sub(r"\{(\w+)\}", r"\1", "Hello! {user}")
'Hello! user'

[issue47052] allow string as sep in _Py_strhex_impl ( bytearray.hex() )

[arne123]

New submission from arne123 :

I use Python to support some C development.
Often I need to convert bytearrays to C like convention:
0x12, 0x34

It would be very convenient for this use case if the separator could be a 
string (like ", 0x") instead of just a single character.

Yes, I assume that's what the OP intended, but then stumbled across the error 
with '\s'.

In any event, I don't think there's a bug here so I'm going to close this.

[issue47050] Cannot install Python 3.10.3 on Windows

[Steve Dower]

Steve Dower  added the comment:

Okay, that kind of makes sense.

If you try to uninstall 3.10.3 (either through Programs & Features, or through 
the installer), how far can you get? Hopefully far enough that one of the 
3.10.2 options will work, or possibly for a new 3.10.3 install to succeed.

Unfortunately, once an install gets corrupted like this, it gets real hard to 
clean things up. The next option is to find a tool that will remove MSI 
metadata from your system so you can just delete the installs that way, clean 
up the files manually, and start fresh. But there's no nice recovery here, I'm 
afraid.

[issue47052] allow string as sep in _Py_strhex_impl ( bytearray.hex() )

[Dennis Sweeney]

Dennis Sweeney  added the comment:

Would there be substantial benefit of a new feature over using the existing 
feature and then calling str.replace()?

>>> b = b'abracadabra'
>>> "0x" + b.hex(":").replace(":", ", 0x")
'0x61, 0x62, 0x72, 0x61, 0x63, 0x61, 0x64, 0x61, 0x62, 0x72, 0x61'

[issue47052] allow string as sep in _Py_strhex_impl ( bytearray.hex() )

[arne123]

arne123  added the comment:

Well, I think there are many ways to solve this in python (e.g. I used 
iteration before, wasn't aware of the sep. at all), but when there is already a 
separator, why limiting it to one character?

[issue47052] allow string as sep in _Py_strhex_impl ( bytearray.hex() )

[Dennis Sweeney]

Dennis Sweeney  added the comment:

In particular, it's one ascii character:

>>> b'abracadabra'.hex('😋')
ValueError: sep must be ASCII.

I wouldn't be completely opposed to allowing longer strings, but since there 
are easy enough ways to do it already, put me at a -0. We can see if anyone 
else is in favor.

[issue46382] dataclass(slots=True) does not account for slots in base classes

[Eric V. Smith]

Eric V. Smith  added the comment:

I don't have a problem saying that for a class to be used as a base class for a 
dataclass, its __slots__ must not be an iterator that's been exhausted. That 
doesn't seem like a very onerous requirement.

I'm also not concerned about people using __slots__ to iterate over the fields, 
but I agree that a documentation note couldn't hurt.

@ariebovenberg: go ahead and submit your PR. Thanks!

[issue47023] re.sub shows key error on regex escape chars provided in repl param

[Matthew Barnett]

Matthew Barnett  added the comment:

I'd just like to point out that to a user it could _look_ like a bug, that an 
error occurred while reporting, because the traceback isn't giving a 'clean' 
report; the stuff about the KeyError is an internal detail.

[issue47053] Reduce de-optimization in BINARY_OP_INPLACE_ADD_UNICODE

[Dennis Sweeney]

New submission from Dennis Sweeney :

There was a discussion here: 
https://github.com/faster-cpython/ideas/discussions/269

Checking for whether the assignment target is the left-hand side, rather than 
just checking for the right refcount, is more stable and reduces the number of 
deoptimizations, and even increases performance on some benchmarks.

Note that `PyUnicode_Append` is already a somewhat expensive function that 
already checks for the right reference counts, so it's fine to let as much code 
as possible get there, even if it will take the slow path -- we mostly just 
want to reduce allocations and avoid the quadratic string concatenation 
otherwise.

These look great.  Currently, coverage.py only tries to distinguish between 
return/yield, which I guess will now be COMPLETED and SUSPENDED?
