ddtrace failure if pytest `no:legacypath` is set

[braingram]

Summary of problem

Usage of legacy pytest path features in ddtrace prevents disabling pytest legacypath (as recommended in the pytest docs).

Running a test suite with ddtrace and -p no:legacypath results in the following error:

How can we reproduce your problem?

I believe (but have not confirmed) that running any test suite with --ddtrace -p no:legacypath will produce the error.

What is the result that you get?

See error above.

What is the result that you expected?

No error due to ddtrace usage of pytest legacy path.

Thanks for bringing this to our attention, @braingram. We'll look into it.

@romainkomorndatadog do you think this could be related to recent changes to the pytest integration?

[romainkomorndatadog]

I don't think it's related to recent changes (we haven't touch our usage of rootdir).

@braingram , from reading this issue, I'm not getting the sense that this is a new error, and that this used to work in the past, is that correct?

[romainkomorndatadog]

I just did a quick "bisect" (with pip, not git) and it looks like this is an issue introduced in 2.x.

Tracking this with CIVIS-9265 .

[romainkomorndatadog]

https://github.com/DataDog/dd-trace-py/pull/7627 is what introduced the incompatibility with -p no:legacypath , although I'm assuming using ITR would also cause an error because of the places we access config.rootdir (like https://github.com/DataDog/dd-trace-py/blob/1.20/ddtrace/contrib/pytest/plugin.py#L83 and https://github.com/DataDog/dd-trace-py/blob/1.20/ddtrace/contrib/pytest/plugin.py#L96 ).

I guess we've not had combinations of -p no:legacypath and ITR usage.

[braingram]

Thanks all for the responses! @romainkomorndatadog you are correct that I don't believe this is a new error (we only started seeing it when we tried to use -p no:legacypath). I can also confirm that config.rootdir usage also causes errors when this option is enabled.

[jamt9000]

Looks like config.rootpath is the non-legacy version
