tmpdir_factory and absolute paths that coincide with tmpdir_factory fails

[zerothi]

Prior to #5686 (I think) one could provide absolute paths to tmpdir_factory. I understand the security issues this brings. However, I had a conftest.py implementation which used tmpdir_factory.getbasetemp() and it self created full paths with the base being getbasetemp().

I think in such cases pytest should not fail since the directory is valid and could easily be checked against.

I.e. the directory/file passed should be resolved and if it is prefixed with getbasetemp then all is good, else fails.

I am only now encountering these problems in Travis, pytest version 5.4.1 (not on my local box, since I haven't updated pytest, I am still on 5.0.1).

See here for the output which creates the fails.

See here for the implementation which itself collects the directories and files that are created.

If anymore information is required, feel free to contact me.

Hmm. Validating that a path is safe just makes me nervous - is there a workaround you could try like calculating the relative paths you want?

Thanks!
I have now made a work-around, but it has some quirks. I'll see if I can simplify it out...
