Test suite hangs on OpenBSD #452

Closed vext01 closed 3 years ago

vext01 commented 3 years ago

Version 0.4.1:

cd /usr/local/pobj/py-neovim-0.4.1-python3/pynvim-0.4.1 && /usr/local/bin/py.test-3

test/test_buffer.py F

And then it hangs... Python sits idle. Deadlock?

If I add -x, we see the failing test is:

__________________________________ test_repr ___________________________________

vim = <pynvim.api.nvim.Nvim object at 0xfa5780da490>

    def test_repr(vim):

E       AssertionError: assert '<Buffer(handle=2)>' == '<Buffer(handle=1)>'
E         - <Buffer(handle=2)>
E         ?                ^
E         + <Buffer(handle=1)>
E         ?                ^

test/test_buffer.py:10: AssertionError
=========================== 1 failed in 0.21 seconds ===========================

Which looks a lot like #416 ?

Any ideas?

vext01 commented 3 years ago

The hang is due to $HOME being set to /nonexistent in the ports tree. So our fault, not yours.

After fixing that, we have failures that look a lot like #416. Will update #416.

I have the same error. I am with Archlinux, the problem happens in the same scenario

test/test_buffer.py .

In my case, the difference is that i changed the hostname (is my personal laptop) before install neovim and pynvim plugin

i changed the hostname with hostnamectl command, and change in /etc/hosts and /etc/hostname too

if i kill the python2 executable running the test (several times) i get this:
