The exception is thrown on accessing the 'to' header, so make that
print(msg['to'])

I didn't send a patch when originally submitting the bugreport in 2019.
I did write a patch about a year later, since there was no response to
the bugreport.

[issue44576] AttributeError: incorrect line identified in Python 3.10

[Andre Roberge]

New submission from Andre Roberge :

Consider the following program

# example.py
one = 1
two = "two"
a = [one
.
two]

Running this program with Python versions before 3.10, yields the following 
traceback:

Traceback (most recent call last):
  File "C:\Users\andre\example.py", line 3, in 
a = [one
AttributeError: 'int' object has no attribute 'two'

The line shown correctly includes the 'int' object. I have verified that this 
is the case for Python 3.6 to 3.9 inclusively.

However, with Python version 3.10.0b3, the following traceback is generated:

Traceback (most recent call last):
  File "C:\Users\andre\example.py", line 5, in 
two]
AttributeError: 'int' object has no attribute 'two'

[issue44577] Probably defect in Python 3.7.11

[Vladislav Kozlenko]

New submission from Vladislav Kozlenko :

After upgrade to 3.7.11 from 3.7.10 WebSockets start failing.
Django==2.1.2
djangorestframework==3.8.2
daphne==2.3.0
channels==2.3.1

>From the 3.7.11 changelog:
Following the controlling specification for URLs defined by WHATWG 
urllib.parse() now removes ASCII newlines and tabs from URLs, preventing such 
attacks.

Probably something is not good here now.

[issue44575] Windows installer prohibits different patches for the same version

[neonene]

neonene  added the comment:

To debug pure python, use embeddable pythons in different folders and copy Lib 
folder from source archive instead of using python3.9.zip.

When using msvc (python3*.lib), I think it's enouth to install python as 
follows or build from source.

1.Copy Installed Python to any folder.
2.Uninstall Python.
3.Install Python with different minor version.

[issue44530] Propagate qualname from the compiler unit to code objects for finer grained profiling data

[Mark Shannon]

Mark Shannon  added the comment:

I suspect that the 0.1% increase is noise.
The size of importlib.h etc show a small decrease, suggesting that the 
information content of the code object has *decreased*.

After all, the qualname has to stored somewhere and moving it from caller to 
callee should make no difference.

Organizing the code object so it wastes less memory is a separate issue.

[issue44578] dict with more than two type parameters doesn't raise a TypeError

[Michael]

New submission from Michael :

dict with three type parameters is legal (e.g., dict[str, str, str]), where I 
expected a TypeError. When using typing.Dict, it does raise a TypeError.

Example in python 3.9:

>>> from typing import Dict
>>> Dict[str, str, str]  # Raises a TypeError, as expected
Traceback (most recent call last):
  File "", line 1, in 
  File "/Users/michaelthe/.pyenv/versions/3.9.6/lib/python3.9/typing.py", line 
275, in inner
return func(*args, **kwds)
  File "/Users/michaelthe/.pyenv/versions/3.9.6/lib/python3.9/typing.py", line 
828, in __getitem__
_check_generic(self, params, self._nparams)
  File "/Users/michaelthe/.pyenv/versions/3.9.6/lib/python3.9/typing.py", line 
212, in _check_generic
raise TypeError(f"Too {'many' if alen > elen else 'few'} parameters for 
{cls};"
TypeError: Too many parameters for typing.Dict; actual 3, expected 2
>>> dict[str, str, str]  # No TypeError here?
dict[str, str, str]

This also works in 3.7 and 3.8:

Python 3.8.11 (default, Jul  6 2021, 12:13:09) 
[Clang 12.0.5 (clang-1205.0.22.9)] on darwin

[issue44576] AttributeError: incorrect line identified in Python 3.10

[Alex Hall]

Alex Hall  added the comment:

I believe this is the outcome of https://bugs.python.org/issue39316 which I 
filed, so I'm pulling in . Naturally I think the new behaviour is not a bug but 
a feature.

I think it's more important for the traceback to show the attribute access 
(`two`) than the value (`one`). That's what the frame was doing at the time 
which led to the error.

The difference becomes even more important when calling a method with no 
arguments. Given this script:

class A:
def b(self):
1 / 0


x = (
A()
.b()
)


The 3.9 traceback points to the line with `A()` in the `` frame, while 
3.10 correctly points to `.b()`, which makes the following line 'in b' make 
more sense.

Where the old behaviour has really gotten to me is when I run the pycharm 
debugger and put a breakpoint on the .b() line and it never gets hit. Not being 
sure what lines 'count', I sometimes defensively put breakpoints on a cluster 
of lines, then spend more time removing them later. Having that fixed in 3.10 
is great.

[issue44579] shutil.copy() inefficient implementation in Windows

[sfmc]

In Windows shutil.copy() uses _copyfileobj_readinto which copies file in user

In Windows there is an fast API to copy file in kernel mode: CopyFile (see

[issue44579] shutil.copy() inefficient implementation in Windows

[Eryk Sun]

Eryk Sun  added the comment:

> In Windows there is an fast API to copy file in kernel mode: CopyFile

The possibility of calling CopyFileEx() for shutil.copy2() is discussed in 
issue 30044. Note that CopyFileEx() is a high-level Windows API function, not a 
"kernel mode" copy. It opens the source and destination files and makes 
multiple system calls in order to copy file data and metadata (e.g. system 
calls such as NtOpenFile, NtCreateFile, NtReadFile, NtWriteFile, 
NtQueryInformationFile, NtSetInformationFile, NtQueryEaFile, NtSetEaFile, 
NtQuerySecurityObject, etc). This includes copying the primary data stream, 
alternate data streams, file attributes, extended file attributes, and security 
resource attributes.

[issue44580] pprint does not work for typing.Mapping

[Hayden Clark]

New submission from Hayden Clark :

If you make a user-defined type that inherits from typing.Mapping (which is an 
alias for collections.abc.Mapping), pprint does not dump the contents, it just 
treats it as an unknown class.
Examining the code, it is explicitly checking for "dict" type, even though it 
is only reading the data.

Here is a reproduction:
from typing import Mapping
from pprint import pprint


class MyMap(Mapping):
def __init__(self, **kwargs) -> None:
self.data = {
k:v for k, v in kwargs.items()
}

def __getitem__(self, k):
return self.data.get(k)

def __len__(self):
return self.data.__len__()

def __iter__(self):
return self.data.__iter__()


info = MyMap(
foo="bar",
baz=MyMap(bar="foo")
)

pprint(info)

[Zachary Ware]

Zachary Ware  added the comment:

The pull request you opened was invalid, because it was just trying to merge 
the `main` branch of the python/cpython repository into the `3.9` branch.  What 
we need instead is a pull request between a branch from `main` in your own fork 
of python/cpython with the change you want to see in a new commit.  You can 
find a more detailed walkthrough in the devguide, or if you prefer to leave it 
for someone else to do that is also a valid option :)

[issue44578] dict/list with more than two type parameters doesn't raise a TypeError

[Ken Jin]

Ken Jin  added the comment:

Sorry, I don't think this will be fixed as it is intentional. 
types.GenericAlias (the type of list[int] or dict[str, str]) does almost 0 
checking for two reasons IIUC:

- Types with wrong number of parameters will usually be caught by your IDE/type 
checker.
- Checking would add complexity and slow down runtime performance. The current 
implementation of GenericAlias in C is intentionally simple.

We can add a note in the docs noting that too many type parameters won't raise 
a TypeError. It would probably be here 
https://docs.python.org/3/library/stdtypes.html#generic-alias-type

BTW, I adjusted the issue's affected versions because this was introduced only 
in 3.9.

[issue44581] Interpreter can execute quickened opcodes in tracing mode

[Mark Shannon]

New submission from Mark Shannon :

This breaks a key invariant of PEP 659.

Inserting `assert(cframe.use_tracing == 0);` at the top of all quickened 
instructions results in several failures when running the test suite.

[issue44579] shutil.copy() inefficient implementation in Windows

[Steve Dower]

Steve Dower  added the comment:

> Note that CopyFileEx() is a high-level Windows API function, not a "kernel 
> mode" copy.

This is true today, but could change whenever Windows feels like changing it. 
If we switch to the native API then we'll get any advantage there automatically.

The only challenge is in managing changes to semantics (that is, anything extra 
we do to "match" Unix that isn't normally how copies work on Windows - 
personally, I'd rather be more native on Windows anyway).

[issue44575] Windows installer prohibits different patches for the same version

[Steve Dower]

Steve Dower  added the comment:

> Why does it have to be so complicated? What is the rationale behind 
> prohibiting different patches in separate folders?

Most users don't want different patches in separate folders - they want to 
update to the latest and greatest and use it everywhere.

Those users who *do* want different versions tend to be well-informed enough to 
figure out alternatives.

You can also grab the packages from https://www.nuget.org/packages/python/ 
which can be extracted anywhere you like and are not stripped down like the 
embeddable package.

[issue44577] Probably defect in Python 3.7.11

[Vladislav Kozlenko]

Vladislav Kozlenko  added the comment:

It will be not easy as I'll need to create some sandbox for you. The current 
code version is not available for sharing.


But ok. For example here is a routing.py file:

from django.conf.urls import url
from channels.routing import ProtocolTypeRouter, URLRouter
from channels.security.websocket import AllowedHostsOriginValidator
from channels.auth import AuthMiddlewareStack
from some_dir import MyConsumer

application = ProtocolTypeRouter({
'websocket': AllowedHostsOriginValidator(
AuthMiddlewareStack(
URLRouter([
url('api/socket/end-point-1', MyConsumer),
])
)
)
})

Let me know if you need more information

Mark Shannon  added the comment:

This is a tricky one.
Which is the "correct" line appears to be subjective.

I'm inclined to leave it as is, as the tracing sequence seems better in the 
case of method chaining.

[issue44479] Windows build doesn't regenerate some files

[Ken Jin]

Ken Jin  added the comment:

@Steve, after this change, the Azure Pipelines commit CI's appx tests started 
failing on main and 3.10.

https://dev.azure.com/Python/cpython/_build/results?buildId=83619&view=results

==
FAIL: test_printer_buttons (idlelib.idle_test.test_help_about.LiveDialogTest) 
(name='license')
Test buttons whose commands use printer function.
--
Traceback (most recent call last):
  File "D:\a\1\b\layout-appx-win32\lib\idlelib\idle_test\test_help_about.py", 
line 65, in test_printer_buttons
self.fail(name + ' full text was not found')

AssertionError: license full text was not found

It seems that idlelib's license isn't included in that specific build.

FWIW, I can't repro this on my own machine. Though I recall you explaining that 
appx has some differences in another issue.

Please take a look if you have the time. Thanks in advance!

Didn't even realise we had a test for it. Maybe it only runs in install-like

I'll simplify the regeneration by just doing it every time. Nothing else

[issue44575] Windows installer prohibits different patches for the same version

[Steve Dower]

Steve Dower  added the comment:

You found your way to the issue tracker where we can help, which is more 
enlightened than most of our other ~20 million users :)

Nuget allows you to download the packages directly. Go to the page I linked and 
choose your version, then find the download link. They have a bit more 
structure in the ZIP file than just a Python runtime, to enable them to 
interoperate properly with a Nuget-based build system (relatively common on 
Windows these days), but you can move the contents around however you like.

And unfortunately, any "options" are not free. Someone has to develop, 
document, test, maintain and support it, and everyone who's been willing to do 
it has chosen to do it independently from the core team (which is great! 
CPython is free open-source software for exactly that reason). Perhaps Anaconda 
would suit your needs better?

[issue44575] Windows installer prohibits different patches for the same version

[Константин Глухов]

Константин Глухов  added the comment:

Hi Steve,

Thank you for taking time to reply. I do appreciate it.

I did try nuget installs but they a little bit weird for my taste.
Anaconda is too bloated.
I also tried python-webinstall.exe /layout and install from .msi, these
work OK for the command line use, but do not work with Vim plugins for some
reason, so I cannot rely on them as I can on a normal Windows install.

As a side note, I think making the install restrictive is more work than
just let it install where user wants to install. The restrictions need to
be coded - don't they? :)

Konstantin

[issue44582] Accelerate mimetypes.init on Windows

[Steve Dower]

New submission from Steve Dower :

mimetypes.init is slow on Windows because of the big registry search, which 
involves touching thousands of entries in order to add a few hundred into the 
initial table.

Things get even worse when audit hooks are enabled, because the winreg methods 
need to be hooked. However, we know that this particular operation is coming 
from core, and so we could skip these hooks.

Both issues can be trivially solved (helped) with a native accelerator function.

Well at this point, the restrictions already exist! So change it now is the 
expensive part.

And having two ways to do something will always be more complicated than one 
way. We can't abandon the existing installation methods.

[issue44582] Accelerate mimetypes.init on Windows

[Steve Dower]

Steve Dower  added the comment:

It's only a rough benchmark, but my timings for `python -c "import mimetypes; 
mimetypes.init()` were ~200ms without the accelerator and ~100ms with the 
accelerator.

Since that includes all of startup, it's actually a better than 50% reduction 
for mimetypes.init(). I'm happy to take that without questioning precisely how 
much better it is ;)

Skip Montanaro  added the comment:

I routinely build with -O0 and have been getting test_gdb failures building the

nice ./configure OPT="-O0 -g3 -Wall" --with-pydebug --with-trace-refs

but test_gdb still fails. Output attached. Note that I have been getting CRC 
mismatches between a couple files. They are copious in the test output, so I

[issue44575] Windows installer prohibits different patches for the same version

[Steve Dower]

Steve Dower  added the comment:

Some quotes from my reply to an off-list email that may be useful for other 
people who encounter this issue:

---

Apps that use Python-based plugins we can't make Just Work - it's up to the 
host application to work with Python installs (or to bundle its own, which is 
easier on Windows). We're happy to help the people who can fix it on their side 
if you know who to work with.

Rather than developing our own installer, it's actually less effort to use the 
standard Windows Installer service to manage installs, and that's the system 
with the restrictions. Coding something from scratch that supports the 
equivalent upgrade/repair/uninstall mechanisms would be considerably more work, 
and we'd end up basically reimplementing it or end up regularly recommending 
people try and delete everything by hand.

We also support the newer Windows MSIX format via the Store, because that's 
even less work and is a better experience for most users. Unfortunately, it's 
even further away from what you want. If your preferences are so strong, you 
may need to do your own builds and manually put them where you need. The Nuget 
packages will let you skip the compile step, and the regular ones will let you 
also skip the "put them where you need" step.

[issue43941] Unit test failure in test_gdb only with -O0

[Pablo Galindo Salgado]

Pablo Galindo Salgado  added the comment:

Skip: I am still unable to reproduce in my machine unfortunately. Could you 
maybe bisect the failures if you can reliably reproduce the problem so we can 
at least narrow it down to one commit?

[issue43941] Unit test failure in test_gdb only with -O0

[Skip Montanaro]

Skip Montanaro  added the comment:

Unfortunately, I'm currently not able to build Python 3.8, 3.9 or 3.10 and get 
a non-failing test_gdb. I'll mess around a bit more, but I'm skeptical I'll 
find something simple. (I wonder if something changed in GDB which is causing 
the failure.)

[issue43126] IOBase.readlines(0) behaviour is inconsistent with documentation

[Andrei Kulakov]

Andrei Kulakov  added the comment:

Thanks for the report!

I agree docs could be improved. Note this method lives in `IOBase` so this 
behavior also applies to the file pointer returned from `open()` builtin.

I've put up the PR here: https://github.com/python/cpython/pull/27061/files

[issue11343] Make errors due to full parser stack identifiable

[Terry J. Reedy]

Terry J. Reedy  added the comment:

I retract my original comment as I now agree with SyntaxError + distinct 
message.

Given Irit's report, I think the remaining question is whether 

A. The implication that 'too many nested parentheses' is compiler specific is 
strong enough, and any thing further should be left to 3rd parties to explain, 
and this issue should be closed as 'out of date'.

B. We should be explicit and add something like 'for this compiler'.

Since Pablo has been working on improving error messages, I would give his 
opinion high weight.

To find the actual limit, I did the following with Win 10, 3.10.0b3, IDLE:

>>> def f(n):
... print(eval('('*n + ')'*n"))
... 
And after some trials, found
>>> f(200)
()
>>> f(201)
Traceback (most recent call last):
  File "", line 1, in 
f(201)
  File "", line 2, in f
print(eval('('*n + ')'*n))
  File "", line 1

()





^
SyntaxError: too many nested parentheses

The error is detected in 'string' line 1, 1-based offset 201, at the final '('. 
 There are 200 spaces before the caret but they are not obvious in this box, 
which does not wrap spaces properly. The end_lineno and end_offset are None, 
None rather than the 1,202 I expected.

[issue44575] Windows installer prohibits different patches for the same version

[Константин Глухов]

Константин Глухов  added the comment:

After reviewing all the suggested options of the "versioned" Windows install I 
came to the conclusion that the "NuGet" path is the easiest.
Assuming x - version, y - patch number, the following steps work

1. Unzip 'Tools' folder of the NuGet archive into Python\3xy
2. Re-install pip to add pip.exe to Python\3xy\Scripts

3xy\python.exe -m pip install -U pip --force-reinstall

It works like a regular install after that.

Switching between versions can be done via a symbolic link:

cmd /c mklink /d 3x 3xy

Optional: Add Python\3x\Scripts;Python\3x to the PATH env variable.
