Problem: autocommands can cause various problems in terminal mode, which can
lead to crashes, for example.
Solution: fix found issues. Move some checks to terminal_check and guard against
autocommands messing with things. Trigger TermEnter/Leave after terminal mode
has changed/restored most state. Wipeout the correct buffer if TermLeave
switches buffers and fix a UAF if it or WinScrolled/Resized frees the terminal
prematurely.
These changes also allow us to remove the buffer restrictions on TextChangedT;
they were inadequate in stopping some issues, and WinScrolled/Resized was
lacking them anyway.
This module is generally used by any tests that need the full Nvim TUI
instead of `screen.lua`. Thus it should live in `functional/` instead of
in `functional/terminal/`.
Specifically, functions that are run in the context of the test runner
are put in module `test/testutil.lua` while the functions that are run
in the context of the test session are put in
`test/functional/testnvim.lua`.
Closes https://github.com/neovim/neovim/issues/27004.
The terminal buffer closes automatically when using `:terminal` and the
command exits without an error. This messes up some tests that expect
the terminal buffer to still be open. We can force the buffer not to
close by passing an argument to `:terminal`. This can be anything, since
the shell-test stub simply prints whatever argument it's given.
Problem:
If shell-test finishes before the next RPC call, TermClose has already
been triggered, so the test fails.
Solution:
Add INTERACT argument so that shell-test keeps running.
Extend the capabilities of is_os to detect more platforms such as
freebsd and openbsd. Also remove `iswin()` helper function as it can be
replaced by `is_os("win")`.
This is essentially a convenience wrapper around the `pending()`
function, similar to `skip_fragile()` but more general-purpose.
Also remove `pending_win32` function as it can be replaced by
`skip(iswin())`.
- Partially fixes#10386 except for the case where the alternate buffer
is the default, empty, first buffer created on startup. #vimlife
- TODO: port patches related to `can_unload_buffer`, maybe that fully
fixes#10386?
