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).

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: tests: "Untitled" file not removed when running Test_crash1_3 alone
with TEST_FILTER (after v9.1.0695)
Solution: Use a TearDown function instead of another test.

Problem: Option insecure flags not copied when splitting window.
Solution: Move window-local insecure flags to winopt_T and copy them
properly (zeertzjq).

(cherry picked from commit 42f1864b62)
Problem: :set doesn't clear local insecure flag like :setlocal does.
Solution: Also clear the local insecure flag when using :set (zeertzjq).
This applies to local options like 'wrap', 'foldtext' and 'foldexpr',
whose global flags are actually never used. For global-local options
like 'statusline' the behavior is already correct, so add some tests.

Problem: 'nowrap' in a modeline may hide malicious code.
Solution: Forcibly use '>' as 'listchars' "extends" if 'nowrap' was set
from a modeline (zeertzjq).
Manual `:setlocal nowrap` disables this behavior. There is a separate
problem with `:set nowrap` that also applies to some other options.

(cherry picked from commit c9f6267402)
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

cmd: expected expected function or table with executable command,

Solution:
- `can_start`: check `config.filetypes` before checking the rest of the
config.

Problem: after #34287 nvim_win_set_config no longer errors when attempting to

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().
