pip freeze outputs deprecated form of VCS requirement

[bersbersbers]

Environment

• pip version: 20.2.4
• Python version: 3.8.6
• OS: Linux

Description

user@host:~/myproj> pip freeze | grep myproj
user@host:~/myproj> pip install -e .
Obtaining file:///home/user/myproj
  Installing build dependencies ... done
  Getting requirements to build wheel ... done
    Preparing wheel metadata ... done
Installing collected packages: myproj
  Running setup.py develop for myproj
Successfully installed myproj
user@host:~/myproj> pip freeze | grep myproj
-e git+git@git.company.com:user/myproj.git@haaaaaaaaaaaaaaaaaash#egg=myproj
user@host:~/myproj>

I am not sure that the -e ... line is intended like this at all, but it certainly uses a format that is deprecated:

pip/src/pip/_internal/req/req_install.py

Lines 639 to 644 in 9a5441c

	if not self.link.is_vcs:
	reason = (
	"This form of VCS requirement is being deprecated: {}."
	).format(
	self.link.url
	)

I assume title was a typo to VCS (version control system) because IIRC pip does not support CVS (Concurrent Versions System).

@DiddiLeija what where you waiting a response for?

Sorry, my misunderstanding got involved here.

@uranusjr, is there any update for this issue?

The legacy URL form is the only format supported for editable installs, so there’s no reasonable action available until someone can finish #9471.
