no, there are some int32 wrinkles to figure out @simonjayhawkins IIRC you use windows.  can you reproduce the failures here? > @simonjayhawkins IIRC you use windows. can you reproduce the failures here?

Not been successful running test suite locally on Windows for a long time. now use Ubuntu in WSL.

last time I tried to debug Windows issues, I seemed to be hit with #38214. (also concerns listlike) can confirm running full test suite still failing for me (with master)

here as a baseline. note the duration. although I think it had hung and I may have interrupted. will run on same hardware with Ubuntu for comparison and also with this branch on Windows shortly.

re test_clipboard, I saw the same failures on a headless Ubuntu machine that I sometimes use, fixed that by

1) adding `export DISPLAY=":0"` to .bash_profile
2) amending the alias I use for tests to `alias ptest="xvfb-run python3 -m pytest pandas/tests --skip-slow --skip-db"`

YMMV
 > re test_clipboard, I saw the same failures on a headless Ubuntu machine that I sometimes use, fixed that by

there's an open issue https://github.com/pandas-dev/pandas/issues/38527 and a potential fix https://github.com/pandas-dev/pandas/pull/38546

I'm using an (headless) desktop machine to run the tests (in WSL) using Windows remote desktop (from laptop).

i've not been too concerned since when I used to use the machine as my primary desktop machine, I always had clipboard errors. (the only difference being is that reruning the tests with --lf and they always then passed) @jbrockmendel good on this? yep
