Environment created from another environment ignores --no-pip, --no-wheel, --no-setuptools options

[xvik]

Issue

Affected: virtualenv 20.0.x

When environment created from another environment with --no-pip option, pip is still installed.
It is working with virtualenv 16.x (regression)

Case:

• Create first environt and install vitrtualenv inside it:
  virtualenv one
  one/bin/python -m pip install virtualenv

• Create second environment with no pip:
  one/bin/python -m virtualenv two --no-pip

Result: pip installed
Expected: no pip should be installed

(same with other flags)

Environment

• OS: ubuntu 19.10
• packages: python3, python3-pip
• pip updated, virtualenv installed with pip

Output of the virtual environment creation

The above case execution:

Hello, a fix for this issue has been released via virtualenv 20.0.11; see https://pypi.org/project/virtualenv/20.0.11/ (https://virtualenv.pypa.io/en/latest/changelog.html#v20-0-11-2020-03-18). Please give a try and report back if your issue has not been addressed; if not, please comment here, and we'll reopen the ticket. We want to apologize for the inconvenience this has caused you and say thanks for having patience while we resolve the unexpected bugs with this new major release.

[sbelharbi]

hi,
sorry, i don't know if i should create a new issue or not. but the version 20.0.23 of virtualenv causes a freeze in the command mkvirtualenv of the package virtualenvwrapper ([website] version: 4.8.4 (https://virtualenvwrapper.readthedocs.io/en/latest/index.html#)). after searching using the keyword create virtual environment via CPython3Posix. none has reported mkvirualenv freezing.

downgrading virtualenv to 16.0.0 which happens to work correctly on another server, allowed mkvirtualenv to work correctly. i use python 3.7.0 installed within conda3. let me know if you need more details. this is the first time virtualenvwrapper hangs.
thanks

[gaborbernat]

please do run the command by setting the environment variable PYTHON_VERBOSE=5, to see more information about what's hanging.

[sbelharbi]

i run with PYTHON_VERBOSE=5 with and without -v and it showed the same thing. let me know if something is wrong. thanks

[gaborbernat]

Eh, dunno what wrapper you're using but make it pass more verbosity flags.

[sbelharbi]

i'm using virtualenvwrapper site 4.8.4.

the command that hangs mkvirtualenv does not have a verbosity flag according to its doc. i tried -v and it seems to help.

when i used mkvirtualenv --help, i get this:

$ mkvirtualenv --help
Usage: mkvirtualenv [-a project_path] [-i package] [-r requirements_file] [virtualenv options] env_name

the issue seems to be originated here:

filelock.Timeout: The file lock 'path-to-home/.local/share/virtualenv/seed-app-data/v1.0.1/3.7/wheels.lock' could not be acquired.

thanks

[gaborbernat]

Is the path not write-able? 🤔 not sure why the path can't be acquired.

[sbelharbi]

this is the permission on the file wheels.lock which seems that i can write on it.

$ls path-to-home/.local/share/virtualenv/seed-app-data/v1.0.1/3.7/
total 2
drwxr-xr-x 2 myid g1 3 Jun 12 15:41 .
drwxr-xr-x 3 myid g1 3 Jun 12 15:41 ..
-rwxr-xr-x 1 myid g1 0 Jun 15 15:09 wheels.lock

link suggests to clean ~/.cache/pip which is done at every login, so it is not the issue. others suggest the possibility of the existence of another lock file/folder, but i am not sure about that since this lock is specific to virtualenv if i understand correctly.
thanks

[gaborbernat]

If you can start with a fresh path-to-home/.local/share/virtualenv or fix permissions on that file would fix it.

[sbelharbi]

• just deleted ~/.local/shared/virtualenv/* and tried mkvirtualenv test10, it hangs the same way. it did create a new file wheels.lock with the same permission.

$ ls .local/share/virtualenv/seed-app-data/v1.0.1/3.7/
total 2
drwxr-xr-x 2 myid g 3 Jun 15 15:51 .
drwxr-xr-x 3 myid g1 3 Jun 15 15:51 ..
-rwxr-xr-x 1 myid g1 0 Jun 15 15:51 wheels.lock

is there something wrong with the permission?
it is weird that the file is empty.

• also, i checked, and there is only one file named wheels.lock in ~.
  thanks

[gaborbernat]

It's alright for it to be empty, as it's only used to hold a lock; not a content. So the existence itself is what locks. Can you provide the full creation log post delete (-vvv)?

[sbelharbi]

ok. i see.

sorry, i don't know how to get this log.

Can you provide the full creation log post delete (-vvv)?

can you tell me the command?

if you are talking about the log of mkvirtualenv test11 after deleting ~/.local/shared/virtualenv/* here it is. thanks

^C1097930 KeyboardInterrupt:  [ERROR __main__:57]

[sbelharbi]

i found out that ipython hangs as well. so, i am not sure that the issue comes from virtualenv (it could be the case because virtualenv 16.0.0 works fine). so, i suggest to stop investigating. something weird is going on in my ~ due to some changes in ~ (move from old to new home). although, if you have any suggestion, do not hesitate.

thanks
