This test is a copy of Test_bufunload_all() and requires too much
additional cleanup for the Windows log message.

back to the terminal buffer.

Problem: Crash when deleting terminal buffer and TermClose deletes
other buffers.
Solution: Close the terminal after restoring b_nwindows.
(cherry picked from commit 7297e9d339)
The test may wipe the wrong buffer if :bdelete switches to another one.
Also remove the builtin TermClose autocommand. It doesn't affect the
tests for now, but still it's better to avoid its interference.
(cherry picked from commit d42fa1753a)
Problem: unlike win_close, win_close_othertab could be used to close the
autocommand window from a different tabpage. This causes aucmd_restbuf to close
the wrong window, potentially causing a crash.
Solution: disallow closing it. Also replace a deprecated use of exc_exec in the
test file.
Fixes#21409.
Problem: TabClosed is fired after close_buffer is called (after b_nwindows is
decremented) and after the tab page is removed from the list, but before it's
freed. This causes inconsistencies such as the removed tabpage having a valid
handle and functions like nvim_tabpage_get_number returning nonsense.
Solution: fire it after free_tabpage. Try to maintain the Nvim-specific
behaviour of setting `<amatch>` to the old tab page number, and the
(undocumented) behaviour of setting `<abuf>` to the buffer it was showing
(close_buffer sets w_buffer to NULL if it was freed, so it should be OK pass it
to apply_autocmds_group, similar to before).
Problem: empty comma-separated patterns in an aupat aren't skipped correctly.
Solution: skip consecutive commas in an aupat.
Also simplify the logic.
(cherry picked from commit 1cde71233f)
Problem: patterns after a buffer-local pattern in a comma-separated aupat are
ignored.
Solution: ensure pat refers to the original buffer after each pattern, not the
buflocal_pat buffer, and when printing make sure it's normalized for
each pattern, not just the first.
Also simplify the logic when printing all autocommands for an event, and ensure
headings aren't repeated for each event when printing autocommands.
(cherry picked from commit 6d2330f50d)
Problem: use-after-free in win_move_after if win_enter autocommands free win1/2.
Solution: set w_pos_changed before calling win_enter.
(cherry picked from commit d1189ea508, also adding
an import of "exec" in the test)
Problem: apply_autocmds function can free both buf_T and win_T pointers
Solution: instead retain winids for WinResized and WinScrolled
autocmds and use curbuf pointer, which is consistent with other uses
of apply_autocmds function
(cherry picked from commit 0a0c349b6f)
Problem: TextChangedT fires depending on whether Nvim needs to update_screen
while in terminal mode. This makes little sense as redraws can be completely
unrelated to the terminal. Also, TextChanged could be fired from changes in
terminal mode after returning to normal mode.
Solution: trigger it when b:changedtick changes, like other such events. Happens
when invalid cells are refreshed, though is no longer affected by cursor
changes. Don't fire TextChanged from changes in terminal mode after leaving.
Unlike the other TextChanged* events, I've elected to not have it be influenced
by typeahead. Plus, unlike when leaving insert mode when no TextChangedI events
are defined, I don't trigger TextChanged when returning to normal mode from
changes in terminal mode (is that a Vim bug?)
Curiously, Vim's TextChangedT is different; it's tied to its terminal cursor
redraws, which triggers pretty eagerly (but is unaffected by unrelated redraws)
- usually *twice* when data is sent to the terminal (regardless of whether it
causes any visible changes, like incomplete escape codes; wasn't true for Nvim).
Not clear to me how this event was actually intended to work, but this seems to
make the most sense to me.
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.
The name of Cmdwin* events were changed to CmdWin* in 8ed2dbf6e2
without explanation. This commit changes them back.
This doesn't affect the creation or execution of autocommands. It only
affects the listing of autocommands.
Problem: there is no way to distinguish between user's explicit
completion stop/cancel and other automated reasons.
Solution: update "cancel" reason to be set only on explicit CTRL-e, and
set intentionally vague "discard" otherwise.
Problem:
Event handler declared with `once=true` can re-trigger itself (i.e. more
than once!) by calling `nvim_exec_autocmds` or `:doautocmd`.
Analysis:
This happens because the callback is executed before deletion/cleanup
(`aucmd_del`). And calling `aucmd_del` before `call_autocmd_callback`
breaks the autocmd execution...
Solution:
Set `ac->pat=NULL` to temporarily "delete" the autocmd, then restore it
after executing the callback.
Fix#25526

When a terminal application running inside the terminal emulator sets
the cursor shape or blink status of the cursor, update the cursor in the
parent terminal to match.
This removes the "virtual cursor" that has been in use by the terminal
emulator since the beginning. The original rationale for using the
virtual cursor was to avoid having to support additional UI methods to
change the cursor color for other (non-TUI) UIs, instead relying on the
TermCursor and TermCursorNC highlight groups.
The TermCursor highlight group is now used in the default 'guicursor'
value, which has a new entry for Terminal mode. However, the
TermCursorNC highlight group is no longer supported: since terminal
windows now use the real cursor, when the window is not focused there is
no cursor displayed in the window at all, so there is nothing to
highlight. Users can still use the StatusLineTermNC highlight group to
differentiate non-focused terminal windows.
BREAKING CHANGE: The TermCursorNC highlight group is no longer supported.
Problem:
- API functions using `try_start` directly, do not surface the
underlying error message, and instead show generic messages.
- Error-handling code is duplicated in the API impl.
- Failure modes are not tested.
Solution:
- Use `TRY_WRAP`.
- Add tests.
Before calling "attach" a screen object is just a dummy container for
(row, col) values whose purpose is to be sent as part of the "attach"
function call anyway.
Just create the screen in an attached state directly. Keep the complete
(row, col, options) config together. It is still completely valid to
later detach and re-attach as needed, including to another session.
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/`.
- `alter_slashes` belongs in `testutil.lua`, not `testnvim.lua`.
- `alter_slashes` is an unusual name. Rename it to `fix_slashes`.
- invert its behavior, to emphasize that `/` slashes are the preferred,
pervasive convention, not `\` slashes.
Problem: `CompleteDone` currently does not specify the reason for why completion was done, which is problematic for completion plugins as they cannot know whether the event was triggered due to the completion being canceled, accepted, or for some other reason.
Solution: Add a `reason` key to `v:event`, which is set by `CompleteDone` to indicate why completion ended.
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`.

Also close Nvim instance before removing log file, otherwise the Nvim
instance will still write to the log file.
Also adjust log level in libuv_process_spawn(). Ref #27660
Problem: Normal mode TextChanged isn't tested properly.
Solution: Combine Test_Changed_ChangedI() and Test_Changed_ChangedI_2()
and also run it on Windows. Fix a typo in main.c.

The changes to filetype.vim are N/A since Nvim always prefers filename
