Ignore inaccessible user config

[JelleZijlstra]

Fixes #2157

[Spacetown]

@JelleZijlstra How can I use this in my requirements.txt? I've only usedversions yet.

Looks good, lets just not be silent about it to save peoples time potentially ...

[cooperlees]

Lets add some logging (atleast @ debug level) so we at least tell the user why their config is not being picked up.

• Could save hours of debugging for someone one day
• Silent swallowing at debug level is evil

[JelleZijlstra]

Good point. I made it just unconditionally print for now. Maybe we'd want to do it only if -v is passed, but that's hard because this code gets executed during argument parsing.

[JelleZijlstra]

@Spacetown for quick testing I'd just manually edit the file (/usr/local/lib/python3.6/dist-packages/black/__init__.py in your case, based on the stack trace in the issue). Beyond that, you can install something from git directly (documented at https://pip.pypa.io/en/stable/cli/pip_install/#git), or you can wait for us to release the fix.

It's up to @cooperlees but I think we might want to do another release to get this fix out, since the bug seems to make Black completely unusable for use cases like yours.

[cooperlees]

I feel this is a super low risk bug fix and releases are easy now.

Let's wait till tomorrow morning pacific time and I'll evaluate cutting another release.

[JelleZijlstra]

Yes, we can also wait for other issues to come in.

@JelleZijlstra On my machine it's working. The result is also available here https://github.com/Spacetown/gcovr/runs/2451934895?check_suite_focus=true.

Thanks @Spacetown! Looks like a missing newline in the output but I think the first message isn't from Black, so that needs to be fixed elsewhere.
