Problem: error set by win_set_buf may leak if autocommands immediately close the
new window.
Solution: free the error set by win_set_buf. (prefer nvim_open_win's error as
it's more important and will cause 0 to be returned)
Problem: split_disallowed seemingly exists to prevent issues from changing
frames to accomodate a split window, which doesn't apply to floats.
Solution: remove the restriction for nvim_open_win, but only for floats.
(continue to check b_locked_split though)
NOTE: like before, the buffer we check b_locked_split for may not actually be
the target buffer "buf", as the later call to win_set_buf can fail to switch to
"buf" due to autocommands. (among other things)
Maybe we could attempt to close the new window in that case (or switch to a
different buffer if that also fails), but this is safer. (and simpler)
Fixes#36857 (and possibly some spurious E242s I've observed from extui)
Problem: vim.keymap.del has 'modes' as it's first argument while vim.keymap.set
has 'mode' as it's first argument despite both 'mode' and 'modes' taking in the
same type input of String or String[].
Solution: Updated vim.keymap.set docs to refer to it's first argument
as 'modes'.
Problem:
Tests that trigger `os_delay` messages may take 1-3 seconds, wasting
build/CI time, since this serves no purpose in tests.
Solution:
- Introduce `msg_delay` for cases where `os_delay` is being used as
a "UI feature".
- Skip `msg_delay` in tests.
Problem:
The q keymap is already set in open_floating_preview, so maparg('q') is not empty.
Solution:
Add a health.style check before setting the q keymap.
Problem: When fuzzy is enabled and the prefix is not empty,
items are not sorted by fuzzy score before calling fn.complete.
Solution: Use matchfuzzypos to get the scores and sort the items
by fuzzy score before calling fn.complete.
Problem:
CursorLine background check used global `normal_bg`, ignoring 'winhighlight'.
Solution:
Use `bg_attr` to get window-local Normal background instead.
Problem:
:messages history include the "search hit BOTTOM, continuing at TOP" message,
which is noise.
Solution:
Set msg_hist_off before giving the warning and reset it after warning.
Refactor capability checks in Client:_supports_registration and
Client:supports_method to properly handle dynamicRegistration and unknown
methods. Now, dynamic capabilities are checked before assuming support for
unknown methods, ensuring more accurate LSP feature detection.
Problem: feed_command, nvim_buf_set_option, nvim_buf_get_number, and exc_exec
are marked as deprecated.
Solution: Remove them from the test units in api/buffer_spec, autocmd/focus_spec,
ui/input_spec, and editor/put_spec.
Some test units only used a few deprecated functions, so creating a separate PR
for each would be excessive. Therefore, several were combined into a single PR.
Problem:
If the last visible line in a window is not fully displayed, this line
may not get injection highlighting. This happens because line('w$')
actually means the last *completely displayed* line.
Solution:
Use line('w$') + 1 for the botline.
This reverts 4244a96774
"test: fix failing lsp/utils_spec #36609",
which changed the test based on the wrong behavior.
Problem: Wrong cursor position after formatting with long 'formatprg'.
Solution: Don't show hit-enter prompt when there are stuffed characters.
Previously a stuffed character at the hit-enter prompt will dismiss the
prompt immediately and be put in the typeahead buffer, which leads to
incorrect behavior as the typeahead buffer is processed after the stuff
buffers. Using vungetc() when KeyStuffed is TRUE can fix this problem,
but since the hit-enter prompt isn't visible anyway (and is likely not
desired here), just skip the prompt instead, which also avoids a wait
when using "wait" instead of "hit-enter" in 'messagesopt'.

Problem:
After bc0635a9fc `vim.wait()` rejects floats
and NaN values.
Solution:
Restore the prior behavior, while still supporting `math.huge`. Update
tests to cover float case.
Problem:
When the terminal shrinks, Neovim tries to recompute the layout and
adjust every window so that the total width matches the new Columns. But
in the scenario of numerous windows split horizontally, there is
not enough space for all of them. The frame width (topframe->fr_width) never
reaches the new Columns value, the logic tries to redistribute this negative
space across child frames, but it triggers the assert.
Solution:
Skip this case in `win_update`.
Problem: CursorLine doesn't consistently highlight text using groups
linked to Normal (e.g., in quickfix, passwd files), while it works
for direct Normal usage.
Solution: Don't let normal background from linked groups override
explicit non-normal backgrounds during attribute combination.
Problem:
`nlua_wait()` uses `luaL_checkinteger()` which doesn't support
`math.huge` since it's double type. On PUC Lua this fails with
'number has no integer representation' error and on LuaJIT this
overflows int.
Solution:
Use `luaL_checknumber()` and handle `math.huge`.
Problem:
The `over_flow` parameter in `grid_draw_bordertext` always added 1 for
the '<' character. As a result, titles that fit exactly were still
truncated with an unnecessary '<'.
Solution:
Adjust `over_flow` only when the actual overflow is greater than 0.
Fix#36872
Problem: When exiting at the end of the more prompt (at the hit enter
prompt) by hitting q the recording mode will be started.

Solution: Don't add the q key to the typeahead buffer

Problem: Wrong display when using setline() at hit-enter prompt
(after 8.2.3204).
Solution: Only skip scrolling for changed lines in top area if it's
scrolled down due to w_topline change. Also add more testing
for what 8.2.3204 fixed (zeertzjq).
closes: vim/vim#18887e72eacceab
Problem:
We truncate the title from start, this is somewhat inconsistent
with the way vim works. Usually we use < to truncate and keep
more trailing characters.
Solution:
Keep more trailing characters.
Problem:
`clint.py` is the last python in our codebase, and beyond that it needs
some cleanup. And it lacks tests, so modifying it can be painful.
Also, we need a way to add ad-hoc lint rules for *Lua*, so it will help
to have our ad-hoc rules for C in the same language (the scripts may
share functions/techniques): https://github.com/neovim/neovim/issues/28372
Solution:
- convert to `clint.lua` (mostly AI-generated, but it now has test
coverage, unlike `clint.py`)
- drop rules that are no longer needed:
- "readability/multiline_string"
- technially still relevant, but very uncommon so doesn't really matter.
- "--line-length"
- Not used in the old clint.py, nor the new clint.lua.
- "comment whitespace" check
- It is enforced by uncrustify.
- "TODO" check
- The `-google-readability-function-size` clang-tidy rule enforces
"TODO(user)" format. (It was already enabled long ago.)
Problem: Wrong display when scrolling with 'scrolloff' and calling
sign_unplace() and setline() in CursorMoved (after 8.2.3204).
Solution: Still scroll for changed lines below the top area when the top
is scrolled down (zeertzjq)

Problem: sort() does not handle large numbers correctly

Use a Lua test for now, as the Vimscript test uses tuples.

Problem:
Every CI log has a lot of noise at the end, which makes it harder to
find relevant test failures:

Solution:
- Skip logging in test-mode.
- This can be reverted later, when these logs are changed to "INFO"
level, per this TODO comment:
```
// TODO(bfredl): This is really ILOG but we want it in all builds.
// add to show_verbose_terminfo() without being too racy ????
WLOG("TUI: terminal mode %d unavailable, state %d", mode, state);
```
