Version detection is broken

ALL software version info

$ pip show param       
Name: param
Version: 1.10.1

Description of expected behavior and the observed behavior

param.Version should not run git command on any random git repository it finds.

Complete, minimal, self-contained example code that reproduces the issue

param.Version.git_fetch runs git remote -v from the path of the file. If this is not a git repository, git will go up in the file tree until it finds a git repository, which can lead to some surprises and unexpected behavior.

The problem first appeared in GeminiDRSoftware/DRAGONS#244, where we run tox and import holoviews, which imports param. The path (self.fspath) in that case /.../dev/DRAGONS/.tox/py39-unit/lib/python3.9/site-packages/param/__init__.py and git returns the remote from our repository:

(Pdb) output
'origin\[email protected]:GeminiDRSoftware/DRAGONS.git (fetch)\norigin\[email protected]:GeminiDRSoftware/DRAGONS.git (push)'

(though Version is called here for param itself, from param/__init__.py).
Then repo_matches contains '', and '' in output is always True...
So it proceeds and parses the version but it crashes with DRAGONS' version. Which is probably not PEP440-compatible (v3.0.0-dev-1250-g9165f26bd-dirty), but that should not be param's problem.

param/param/version.py

Lines 177 to 185 in bbc1df8

	output = run_cmd([cmd, 'remote', '-v'],
	cwd=os.path.dirname(self.fpath))
	repo_matches = ['', # No remote set
	'/' + self.reponame + '.git' ,
	# A remote 'server:reponame.git' can also be referred
	# to (i.e. cloned) as `server:reponame`.
	'/' + self.reponame + ' ']
	if not any(m in output for m in repo_matches):
	return self

Even better, when importing param in a fresh virtualenv, it's __version__ will not be correct in some case. I use pyenv so fspath is /home/me/.pyenv/versions/dragons/lib/python3.9/site-packages/param/__init__.py and thus param.__version__ will actually report pyenv's version ... :

@jlstevens Wasn't this fixed?

[jlstevens]

Yes it was fixed on autover here: holoviz-dev/autover#67 and needs to be propagated to param.

[jlstevens]

I've ported the fix in #469
