[issue38583] The activate script in Windows is not correct for venvs created in git-bash

[Mo]

New submission from Mo :

When creating a virtual environment on Windows from git-bash (using python -m 
venv), VIRTUAL_ENV in the activate script is set using a windows style path 
(C:\some\path) instead of the bash style (/c/some/path).

This means the system python and pip get used, despite the user thinking they 
are working in a venv after sourcing activate.

As activate is a bash script, the paths in it should always be in the bash 
style, regardless of platform.

This is described in a stack overflow issue here: 
https://stackoverflow.com/questions/57758841/windows-virtualenv-created-via-gitbash-using-system-python

I have confirmed the behaviour in 3.7.3, 3.7.4, 3.7.5 and 3.8.0.

[issue38583] The activate script in Windows is not correct for venvs created in git-bash

[Mo]

Mo  added the comment:

The issue comes as a result of abspath on line 59 of venv/__init__.py:
env_dir = os.path.abspath(env_dir)

This returns a Windows-style path, and os.path.abspath returning in this way is 
*probably* correct, as the OS is Windows, despite trying to forget that by 
using bash.

It is still my view that the activate script is a bash script, and therefore 
should only contain paths in that style, but the simple solution to this issue 
is to change the double quotes around the definition of $VIRTUAL_ENV in the 
activate script to single quotes. It works. The output of "which python" is a 
bit odd, but this is clearly a quirk beyond Python's control.

[issue38583] The activate script in Windows is not correct for venvs created in git-bash

[Mo]

Mo  added the comment:

I had also tested with pathlib and posixpath and come to the same conclusion.

As suggested by you, I looked into `activate` determining path when run. I 
believe this should do the trick (My bashfoo isn't strong, this is mostly from 
https://stackoverflow.com/a/179231):

pushd . > /dev/null
SCRIPT_PATH="${BASH_SOURCE[0]}"
if ([ -h "${SCRIPT_PATH}" ]); then
  while([ -h "${SCRIPT_PATH}" ]); do cd `dirname "$SCRIPT_PATH"`; 
  SCRIPT_PATH=`readlink "${SCRIPT_PATH}"`; done
fi
cd `dirname ${SCRIPT_PATH}` > /dev/null
cd .. > /dev/null
SCRIPT_PATH=`pwd`;
popd  > /dev/null

VIRTUAL_ENV="$SCRIPT_PATH"

[Mo Jia]

Mo Jia added the comment:

@Roundup Robot . Clone the newest 3.4 tag. The unicode problem is ok now .
@Zachary Ware , don't change anything after clone from the repo. What i do is 
just cd python src dir and runing : Tools\buildbot\build.bat .  the openssl 
verison is 1.0.1g . Seem the external.bat don't build openssl . I see the 
readme " The ssl.vcxproj sub-project simply invokes PCbuild/build_ssl.py,   
 which locates and builds OpenSSL." Seem I don't need build the openssl by 
handle .  After meet the error , I open the sln by vc2010 , and choose the ssl 
project build . Here is another error :

[issue29297] python3 open() does not check argument type before attempting to read() or write()

Python3 open(), read(), or write()doesn't check argument type before action

[Mo Ali]

Mo Ali added the comment:

Serhiy,

I expected a type error or a filenotfound like you received, however mine 
doesn't return the same. It just hangs.  I've attached a picture.  Also, I 
meant this to be for 3.6 not 3.5.

>>> test = False
>>> with open(test) as f:
... fail = f.read()

[issue29191] liblzma is missing from pcbuild.sln

[Mo Jia]

Mo Jia added the comment:

I think let user add the liblzma project by hand is not good enough. While the 
build.bat don't have this problem. So they should work similar.

[issue46703] boolean operation issue (True == False == False)

[jung mo sohn]

New submission from jung mo sohn :

In python 3.6.8, 3.7.3, 3.7.4, 3.7.5, 3.7.12, 3.8.8 versions, the output is 
False as shown below.

Python 3.7.5 (tags/v3.7.5:5c02a39a0b, Oct 15 2019, 00:11:34) [MSC v.1916 64 bit 
(AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> print(True == False == False)
False

However, in the openjdk1.8 version, the output is "true" as shown below. 

public class Test {
public static void main(String[] args) throws Exception{
System.out.println(true == false == false);
}
}

> java Test
true

In my opinion, "True" seems to be correct.
