Problem: :fclose may crash Nvim if autocommands close floats prematurely.
Alternatively, :fclose may call win_close for windows not in curtab if
autocommands change curtab or move windows between tab pages via
nvim_win_set_config (may not crash, but is wrong).
Solution: check win_valid before calling win_close.

Backports #36134.
Problem
Similar to https://github.com/neovim/neovim/pull/33257, but for the date
component. When timezone is behind UTC the epoch date of individual
components mismatch causing the test to fail.
Solution
The `epoch` variable is created using `os.date` with a `!`, which means
format the date in UTC instead of local timezone:
https://www.lua.org/manual/5.1/manual.html#pdf-os.date.
Since the individual components like year, month, and day are expected
to match `epoch` they should all be created using a `!` as well.

Problem: Window may have wrong height if resized from another tabpage.
Solution: Improve check for whether a tabline has been added (zeertzjq).

(cherry picked from commit 28355050a8)
Problem: after #35601, nvim_open_win incorrectly attempts to set the size of a
split window to 0 if it wasn't specified.
Solution: only attempt to set the size again if it was actually specified. This has the effect of defaulting to half the size of the parent window (or it may be equalized with other windows to make room), like before.
Fix#36080
(cherry picked from commit d7472c0617)
Problem: 'cursorlineopt' "screenline" isn't redrawn when moving cursor
and then using line("w0") and :retab that does nothing.
Solution: Call redraw_for_cursorcolumn() when setting a valid w_virtcol
(zeertzjq).

(cherry picked from commit ba47cb7eda)
Problem: vertical separator of 'winfixwidth' windows may remain if they
become right-most windows from closing windows to the right.
Solution: Don't implicitly rely on frame_new_width to fix vseps, as the
call may be skipped for 'winfixwidth' windows to preserve
their width; do it explicitly in winframe_remove (Sean Dewar).
Note that I prefer win_new_width here over setting w_width directly, which
would've previously been done by win_split_ins after frame_add_vsep, as this
wasn't true for winframe_remove.
Though the equivalent issue of bottom 'winfixheight' windows leaving stray
statuslines with &ls=0 doesn't seem to exist, test it anyway.
closes: vim/vim#18481620c655677
Nvim: calling win_new_width over setting w_width directly is especially
important in making sure stuff like w_view_width is correct here.

Problem: :trust is executed even when inside false condition.
Solution: Make skip_cmd() return true for CMD_trust, as ex_trust() does
not handle eap->skip itself.
(cherry picked from commit 2f35221774)
Problem: requested window size passed to nvim_open_win for splits may be ignored
by win_split_ins if it decides to forcefully equalize window sizes instead (e.g:
in an attempt to make room for the new window).
Solution: try to set the size again if it differs from what was requested.

Use only a single clear() call in some test/functional/vimscript/ test
files whose test cases have very little side effect.
A downside of using a single clear() is that if a crash happens in one
test case, all following test cases in the same file will also fail, but
these functionalities and tests don't change very often.
Problem: Wrong display with 'smoothscroll' and long wrapped virtual
text at EOL.
Solution: Handle w_skipcol inside long wrapped virtual text at EOL
(zeertzjq).

Problem:
If there are 2 language servers with different trigger chars (`-` and
`>`), and a keymap inputs both simultaneously (`->`), then `>` doesn't
trigger. We get completion items from server1 only.
This happens because the `completion_timer` for the `-` trigger is still
pending.
Solution:
If the next character arrived enough quickly (< 25 ms), replace the
existing deferred autotrigger with a new one that matches this later
character.
(cherry picked from commit e69b81ad94)
Overriding vim.lsp.handlers['textDocument/formatting'] doesn't work here
because fake_lsp_server_setup() uses a table with __index to specify
client handlers, which takes priority over vim.lsp.handlers[], and as a
result the overridden handler is never called, and the test ends before
the vim.wait() even finishes.
Instead, set a global variable from the handler that is actually reached
(by vim.rpcrequest() from client handler), and avoid stopping the event
loop too early.

Problem:
`gx` does not work on tags in help buffers to open the documentation of that tag in the browser.
Solution:
Get the `optionlink`, `taglink` and `tag` TS nodes and set extmark "url" property.
`gx` then discovers the extmark "url" and opens it.

This fixes the following warning in tests with ASAN or TSAN:
-------- Running tests from test/functional/lua/watch_spec.lua
RUN T4253 vim._watch watch() ignores nonexistent paths: 29.00 ms OK
nvim took 2006 milliseconds to exit after last test
This indicates a likely problem with the test even if it passed!
Problem:
LSP logs show misleading "cannot start" messages when editing a filetype
NOT listed in the `config.filetypes` field.
[ERROR][2025-09-13 18:55:56] …/runtime//lua/vim/lsp/log.lua:151
"cannot start cssls due to config error: …/runtime//lua/vim/lsp.lua:423:
cmd: expected expected function or table with executable command,
got table: 0x0104701b18. Info: vscode-css-language-server is not executable"
Solution:
- `can_start`: check `config.filetypes` before checking the rest of the
config.
(cherry picked from commit 2f78ff816b)
Problem: after #34287 nvim_win_set_config no longer errors when attempting to
split from a floating window only if "win" is 0.
Solution: fix the regression, reduce the scope of "parent" and similar checks to
only where it's currently used and add test coverage for the errors.
(cherry picked from commit da39966a3a)
Problem: a horizontal separator may be added to a window that doesn't need one
if there is no room when moving a different window.
Solution: only restore a hsep in winframe_restore when the global statusline is
enabled.
(cherry picked from commit bf5f7c1591)
Problem:
with `foldmethod=expr foldexpr=v:lua.vim.treesitter.foldexpr()
foldminlines=0`, deleting lines at the end of the buffer always
reports an invalid top error, because the top value (i.e. the
start line number of the deletion) is always 1 greater than
the total line number of the modified buffer.
Solution:
remove the ml_line_count validation
(cherry picked from commit d73cfefed5)
Problem: many FileType autocommands assume curbuf is the same as the target
buffer; this can cause &syntax to be restored for the wrong buffer in some cases
when TSHighlighter:destroy is called.
Solution: run nvim_exec_autocmds in the context of the target buffer via
nvim_buf_call.
(cherry picked from commit 3ec63cdab8)
Problem: on_detach may be called after buf_freeall and other important things,
plus its textlock restrictions are insufficient. This can cause issues such as
leaks, internal errors and crashes.
Solution: disable buffer updates in buf_freeall, before autocommands (like the
order after #35355 and when do_ecmd reloads a buffer). Don't do so in
free_buffer_stuff; it's not safe to run user code there, and buf_freeall already
runs before then; just free them to avoid leaks if buf_freeall autocommands
registered more for some reason.

Problem:
Buffer-updates on_detach callback is invoked before buf_freeall(), which
deletes autocmds of the buffer (via apply_autocmds(EVENT_BUFWIPEOUT,
...)). Due to this, buffer-local autocmds executed in on_detach (e.g.,
LspDetach) are not actually invoked.
Solution:
Call buf_updates_unload() before buf_freeall().

Problem: Ctrl-G/Ctrl-T does not ignore the end search delimiter
(irisjae)
Solution: Check if the pattern ends with a search delimiter and ignore
it, unless it is part of the pattern.

Problem:
Cursor is visible in "hidden" floating window.
Solution:
Hide cursor when curwin is a hidden floating window.
Show cursor after returning to a normal (non-hidden) window.

- Add delimiter between function signature and documentation, matching hover formatting
- Show title only if there are multiple clients or multiple signatures
- Avoid duplicating the title inside the window if it's already shown in the border
(cherry picked from commit d26db4bfbf)
Problem: make_floating_popup_options only shows when opts.border is explicitly set, ignoring global winborder setting
Solution: check both opts.border and vim.o.winborder when determining whether to show title
(cherry picked from commit 5b1b46ea5a)
Problem: Using `addr` without `range` in nvim_create_user_command gives
"No range allowed" error, inconsistent with `:command -addr` behavior.
Solution: Set EX_RANGE flag when `addr` option is specified to match
`:command` behavior.
(cherry picked from commit 22df649210)
Avoid duplicate text when jumping back to a choice node. Set cursor to
end of tabstop range and prioritize current choice in completion items.
(cherry picked from commit 628d569a59)
When right_gravity is set to true for deactivating tabstop expansion we
have to set end_right_gravity to false to avoid expanding the tabstop
region on the right side. Vice versa for activating tabstop expansion
again.
