Multigrid UI :quit closes multiple windows in tab

[akiyosi]

• nvim --version: v0.4.0-321-g9a1675b06

• Vim (version: ) behaves differently? yes

• Operating system/version: macOS

• Terminal name/version: Not using a terminal

Steps to reproduce using nvim -u NORC

gonvim [-u NONE]
:e /path/to/somefile.vim
:tabnew
gt
:vsp
:q

Actual behaviour

The first tab disappears when you do the abobe steps

Expected behaviour

The first tab should remain because it split the window with :vsp.

The following is the state of reproduction.
I'm testing with gonvim

nvim commit: 9a1675b06:

nvim commit: 0aba4d825:

is there something significant about 9a1675b and 0aba4d8? Was the behavior bisected to one of those commits? I can't tell from the gifs.

[akiyosi]

I haven't seen enough of these commit differences, but the behavior of the GUI in multigrid UI seems to change between those commits.

Can you write a Lua screen test showing the problem? See test/functional/example_spec.lua for an example.

You can run the test like this:

TEST_FILE=test/functional/example_spec.lua make functionaltest

[akiyosi]

I confirmed that this issue can be detected by neovim's test test/functional/ui/multigrid_spec.lua. That is, even with the following operations in multigrid_spec.lua, problems occur on the GUI side but the test succeeds.

vsplit
wincmd l
split
wincmd h
q

I trace the events notified to the GUI side in detail, and it seems that grid_destroy has been sent for two grids by the operation q in the GUI. I have not identified the cause why it is sent twice.

I continue to investigate this issue.

I'm very very sorry.😓
This was a bug on the GUI side. I was sending close command to nvim on the win_close.
@Mariappan solved this problem.
