[issue38905] venv python reports wrong sys.executable in a subprocess on Windows

I get the same result as activating (i.e. shows the base interpeter). All 
results in cmd.exe as well.

PATH is as expected, the venv’s Scripts directory at the front after 
activation. I (only) have a python.exe from Windows Store in PATH. The one 
reported by subprocess is not in PATH.

I’ll try to find a clean machine (maybe a VM) and try whether I can replicate 
this. BTW the problematic versions for me was 3.7.5 and 3.8.0.

[issue38861] zipfile: Corrupts filenames containing non-UTF8 characters

[John Goerzen]

John Goerzen  added the comment:

I can tell you that the zip(1) on Unix systems has never done re-encoding to 
cp437; on a system that uses latin-1 (or any other latin-* for that matter) the 
filenames in the ZIP will be encoded in latin-1.  Furthermore, this doesn't 
explain the corruption that extractall() causes.

I think the Python implementation is adhering to the zip specification.

[issue38905] venv python reports wrong sys.executable in a subprocess on Windows

[Eric V. Smith]

Eric V. Smith  added the comment:

Your failing test case with 3.7 works for me.

If you don't use activate.bat, but just run the venv's python directly, what do 
you see? I get:

>py -m venv fooenv

>fooenv\Scripts\python -V
Python 3.7.0

>fooenv\Scripts\python -q
>>> import subprocess
>>> subprocess.check_output(['python', '-c', 'import sys; 
>>> print(sys.executable)'])
b'C:\\Users\\XXX\\fooenv\\Scripts\\python.exe\r\n'

What shell are you using? Above is with cmd.exe.

If you "echo %PATH%" after activate.bat, what do you see?

Before running activate.bat, do you have a python.exe in your path? If so, is 
it the one that subprocess is reporting?

[issue38901] Add a CLI flag to venv to use the pwd basename as the prompt

[Julien Palard]

Julien Palard  added the comment:

I like the idea and I think I will use it!

As it's a bit long to type, I'm searching if other shorter variants could be 
usefull like:

python3 -m venv --here
python3 -m venv --cwd
python3 -m venv --project

being the equivalent of `python3 -m venv --basename-prompt venv`, but I'm not 
satisfied with the names (and it enforces using "venv" as a directory name)...

[issue38547] test_pty fails when using setsid()

[David Bolen]

David Bolen  added the comment:

I think fixing the underlying pty issue should certainly be the goal, but the 
question is whether the process group change should remain active in the 
meantime, as its presence is causing a regression in the tests.  I think such 
cases in the past are usually rolled back, right?

I was originally on the fence since process groups address a real problem, 
especially in interactive testing, while creating an arguably aesthetic issue 
for my case of the buildbots (a warning rather than failure).

But Pablo's point about a normal manual full test run failing (not a warning as 
with the buildbots) feels persuasive since that's probably as common as the 
issue being addressed by the change.  Even if pre-existing, the pty failure is 
exposed by the process group change, so it might be best for the process group 
change to wait on fixing the pty issue.

I don't know how to weigh the relative impact though, e.g,. how many people are 
likely to run into each failure case.  There's probably more people doing a 
normal test run than breaking out of such tests though.  At the least, it's a 
worst impact than just the warnings on the buildbots.

Perhaps an intermediate fallback could be gating the process group change 
behind a regrtest option (opt-in) which could then preserve its benefits upon 
request, without negatively impacting the default test process, whether manual 
or on the buildbots.

At least until resource is available to resolve the pty issue.

What does this buy you beyond using

? Perhaps I'm not understanding what you're getting at - how about an example

I love process groups and they are awesome. But having these test being re-run 
on every buildbot and failing on my machine when just running test with -j is 
very annoying.

What do you mean by "limited"?

Process groups really help to prevent to leak grandchild processes in 
multiprocessing tests, when tests are interrupted manually by CTRL+C or by a 
timeout (sadly, only when the timeout is handled by regrtest, not when it's 
handled by faulthandler).

See bpo-38502 for the rationale.

[issue38906] copy2 doesn't copy metadata on Windows and MacOS

[Eryk Sun]

Eryk Sun  added the comment:

In Windows, using CopyFileExW and CreateDirectoryExW (with a template 
directory, for copytree) doesn't agree with how shutil implements copying with 
separate copyfile and copymode/copystat functions. We'd have to extend 
copyfile() to support alternate data streams, and we'd have to extend 
copystat() to support file attributes, extended attributes, and 
security-resource attributes. Or we'd have to abandon consistency between copy2 
and copyfile+copystat.

[issue38625] SpooledTemporaryFile does not seek correctly after being rolled over

[R. David Murray]

R. David Murray  added the comment:

The docs currently say "The returned object is a file-like object whose _file 
attribute is either an io.BytesIO or io.StringIO object (depending on whether 
binary or text mode was specified) or a true file object, depending on whether 
rollover() has been called."  The fact that taking an iterator gets you 
whatever the *current* _file object is is implied by that but not made 
explicit.  A doc update to make that explicit would probably be appropriate.

[issue38862] IDLE: Include end newlines in whitespace fix.

[Terry J. Reedy]

Terry J. Reedy  added the comment:

Currently, iomenu.IOBinding.fixnewlines makes sure that when a non-empty 
non-Shell file is saved (and possibly run), it ends with at least 1 newline.  
At one time, I believe, compile needed this, and it is still good practice.  
(Git diffs note the absence of a final newline.)

I originally planned to incorporate possible newline addition into do_rstrip, 
in anticipation of calling do_rstrip on save, but I have changed my mind, at 
least for the present.  That code can stay where it is.  If someone explicitly 
runs Strip Trailing Whitespace, adding a newline would sometimes be desired, 
but would sometimes be unexpected and possibly a nuisance.  do_rstrip will 
ensure that non-Shell files end with at most 1 newline.

My revised intent is that once we strip on save, saved files should be  
properly formatted for use or merging into a repository.

[issue38672] mimetypes.init() fails if no access to one of known files

[R. David Murray]

R. David Murray  added the comment:

I haven't looked at this in detail, but here are my general thoughts: I think 
it would be reasonable to expect that the module would function even if the 
file permissions are screwed up, similar to how unix commands that try to read 
.netrc will (try to) function even if its permissions are wrong.  I would, 
however, expect the module to emit a warning in that case.  I'm of two minds 
about the behavior when the caller specifies filenames explicitly.  I could see 
that going either way, but I lean slightly toward making the behavior 
consistent.  While the programmer might appreciate the traceback, the user of 
the program would probably appreciate the "try to keep going" behavior, since 
the filenames provided will often be in the same class of "standard defaults" 
as the existing well known files are, just in the context of that particular 
application.  But like I said, that is just a lean, and I could go the other 
way on this as well :)

I haven't looked at the isflie issue, but it seems reasonable that if the path 
exists we should make sure it is a file before reading it...but perhaps readfp 
will effectively do that?  Write a test and see what happens :)

I don't know whether to call this change a bug fix or a feature, so I guess 
we'd default to feature unless someone can tilt the balance with an argument :)

The "correct" solution here (as far as I remember, its has been a while since 
I've had time to even looked at the _header_value_parser code) would be to add 
a new 'invalid-msg-id' token, and do this:

message_id = MessageID()
try:
token, value = get_msg_id(value)
message_id.append(token)
except HeaderParseError as ex:
message_id = InvalidMessageID(value)
message_id.defects.append(InvalidHeaderDefect(
f"Invalid msg_id: {ex}"))
return message_id

[issue38908] Troubles with @runtime_checkable protocols

[Ivan Levkivskyi]

New submission from Ivan Levkivskyi :

The PEP 544 specifies that:

A protocol can be used as a second argument in isinstance() and issubclass() 
only if it is explicitly opt-in by @runtime_checkable decorator.

It is not specified exactly whether this should be enforced by static type 
checkers or at runtime. Currently it is enforced in both cases: mypy flags this 
as error, and a TypeError is raised at runtime.

There is however a problem with current runtime implementation: abc and 
functools modules may call issubclass() on non-runtime checkable protocols if 
they appear as explicit superclasses. This is currently solved by a 
sys._getframe() hack in  typing module.

The problem is that current solution is incomplete. For example, the TypeError 
is not raised in the case of non-method protocols:

>>> class P(Protocol):
... x: int
... 
>>> 
>>> class C: ...
... 
>>> isinstance(C(), P)
False  # should be TypeError

I tried to fix it this morning but after an hour of attempts to tweak the 
existing hack I gave up. It looks like there are only two reasonable solutions:

* Don't enforce @typing.runtime_checkable at runtime, make it a 
type-checker-only feature (like @typing.final).
* Add a little helper to abc module that would skip classes in MRO for which 
C._is_protocol is True but C._is_runtime_protocol is False.

Any thoughts/preferences?

[issue38907] Add IPv6 Dual-Stack control for http.server

[JIanqiu Tao]

New submission from JIanqiu Tao :

In Python 3.8+, when we run the http.server in a PC that support IPv6, it will 
bind IPv6 socket normally. On Linux or some other platforms, it also bind IPv4, 
that's pretty good, but on Windows, it doesn't work and "--bind 0.0.0.0" have 
to be provided to make it works in IPv4 environment.
In another case, once someone only want the http.server provide service in IPv6 
environment, but linux will still bind IPv4 socket automatically.

Could we add a argument such as "--ipv6-only" for http.server and open the 
support of Dual-Stack socket by default?

[issue37063] Incorrect application of func.__defaults__ by inspect's signature APIs

[Batuhan]

Batuhan  added the comment:

As mentioned in docs, getfullargspec is based on signature() and signature 
objects doesnt keep record of all defaults. It tries to map defaults with 
parameters but if you have less default then total parameter amount it will 
discard rest of defaults. IMHO this isn't a bug.

[issue37292] _xxsubinterpreters: Can't unpickle objects defined in __main__

[Lewis Gaul]

Lewis Gaul  added the comment:

Just to move the conversation from the subinterpreters project repo to here...

I'm going to take a look at how this is done by subprocess using the example 
provided by Guido:

import os
from concurrent.futures import ProcessPoolExecutor
from multiprocessing import get_context

class C:
def __getstate__(self):
print("pickled in %d" % os.getpid())
return {}

def __setstate__(self, state):
print("unpickled in %d" % os.getpid())

def hello(self):
print("Hello world")


if __name__ == "__main__":
with ProcessPoolExecutor(mp_context=get_context("spawn")) as ex:
ex.submit(C().hello).result()

Output:

pickled in 23480
unpickled in 23485
Hello world

[issue38906] copy2 doesn't copy metadata on Windows and MacOS

[Gregg Tavares]

New submission from Gregg Tavares :

MacOS have extended file attributes. Windows has both extended file attributes 
and alternate streams. In both OSes copy/cp and of course the Finder and 
Windows Explorer copy all this data. Python copy2 does not. 

On Windows it seems like CopyFileW needs to be called to actually do a full 
copy.

https://docs.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-copyfilew

On MacOS it appears to require copyItem

https://developer.apple.com/documentation/foundation/filemanager/1412957-copyitem

It's kind of unexpected to call a function to copy a file and have it not 
actually copy the file and have the user lose data

Windows example

[issue38905] venv python reports wrong sys.executable in a subprocess on Windows

[Tzu-ping Chung]

Tzu-ping Chung  added the comment:

3.6 works correctly on Windows:

> py -3.6 -m venv test36
> test36\Scripts\activate.bat
>>> import subprocess
>>> print(subprocess.check_output(['python', '-c', 'import sys; 
>>> print(sys.executable)']))
b'C:\\Users\\uranusjr\\Downloads\\test36\\Scripts\\python.exe\r\n'

So it seems the problem is introduced sometime after.

[issue38905] venv python reports wrong sys.executable in a subprocess on Windows

[Tzu-ping Chung]

Tzu-ping Chung  added the comment:

Linux works correctly (Ubuntu with self-compiled Python 3.7.5)

$ python3.7 -m venv fooenv
$ . fooenv/bin/activate
(fooenv) $ python -c "import sys; print(sys.executable)"
/home/uranusjr/fooenv/bin/python
(fooenv) $ python -q
>>> import subprocess
>>> subprocess.check_output(['python', '-c', 'import sys; 
>>> print(sys.executable)'])
b'/home/uranusjr/fooenv/bin/python\n'

[issue38905] venv python reports wrong sys.executable in a subprocess on Windows

[Tzu-ping Chung]

New submission from Tzu-ping Chung :

To reproduce:

> py -m venv fooenv
> fooenv\Scripts\activate.bat
(fooenv) > python -c "import sys; print(sys.executable)"  % This is correct
C:\Users\uranusjr\Downloads\venvtest\Scripts\python.exe
(fooenv) > python -q
>>> import subprocess
>>> subprocess.check_output(['python', '-c', 'import sys; 
>>> print(sys.executable)'])
b'C:\\Users\\uranusjr\\AppData\\Local\\Programs\\Python\\Python37\\python.exe\r\n'

The output shows the base interpreter, not the interpreter in venv. Not sure 
whether this is a venv or subprocess problem.
