ArrayOf metadata existed before the LuaCATS type documentation refactor and is
useful to typed clients consuming api_info().
Keep Tuple metadata normalized to Array, since tuple element types can be mixed,
but preserve ArrayOf(...) for exported API metadata.

Problem: The table `history` in treesitter/_select.lua stores references
to previously selected TSNodes, but a TSNode needs to keep its
whole TSTree alive in memory, which may be kept alive even
after closing the buffer to which this history corresponds.
Solution: Store just the bits of information from the TSNode we need to
go back in selection history (the range and ID), without
referencing the TSNode itself.
(cherry picked from commit bcfc2037ef)
Problem: The function visual_select() in treesitter/_select.lua is
executing `:normal! v<Esc>` to ensure that `gv` later goes
back to character Visual mode, but doing so when mode() is
already `v` first switches back to the Normal mode, then
executes <Esc>, which causes a beep.
Solution: Check if the mode() is already `v` and avoid any switching in
that case.

Problem: LspNotify autocmds were not being triggered for didChange
requests when being used during undo/redo (and possibly other) actions.
autocmds are blocked when calling on_lines() callbacks while doing the
undo/redo action.
Solution: Defer firing the autocmd until after the action is complete.
This is closer to what existed before, but now there's a check in the
deferred function to only fire the autocmd if the client is still
active and the buffer is still attached, if applicable.
(cherry picked from commit 3c924d13fe)
Problem: LspNotify never passed a buffer when executing the autocmds, so
buffer-local LspNotify autocmd subscriptions didn't have the correct buf
in the event metadata. It was also wrapped in a schedule() so the actual
autocmd was delayed until after the event loop.
This could result in the wrong buffer receiving the notification if
multiple LspNotify autocmds with buffer filters were added. Only the
"latest" one would actually receive non-buffer-filtered autocmds, not
the matching one. It also caused listeners to receive the notification
"out of sync" with when the notification is actually sent. If a buffer
is being deleted (which fires a textDocument/didClose notification), the
notification is scheduled and fired after the buffer is already gone.
Solution: For LSP notifications that pertain to a particular buffer, set
it when executing the LspNotify autocmds so the callback functions that
are filtered on that buffer will get the correct notifications and the
metadata buf field will be correct. Additionally, there is no need to
wrap the LspNotify callback in vim.schedule when it can be called inline
when the notification to the rpc server is fired.
This is tested by removing now-unnecessary autocmds from semantic tokens
(InsertEnter and BufWinEnter should no longer be necessary now that
requests are fired by LspNotify). Without this fix, simply modifying a
buffer doesn't actually trigger LspNotify correctly, and the test for
that fails.

Problem: When multiline semantic token support was introduced, the loop
that finds the end line for a particular token didn't sanitize the token
length sent back by the LSP server. If the server returned an overflowed
length (near uint32 max), neovim would burn cpu and loop for an
extremely long time while trying to find the "end line" represented by
the massively large token, causing neovim to seemingly hang.
Solution: Stop looping once the calculated end_line reaches the actual
last line of the buffer.

(cherry picked from commit 6bc6461eac)
Co-authored-by: jdrouhard <john@drouhard.dev>
This was initially added so that the __NVIM_DETACH environment variable
can be added to the jobs started in this test. That environment variable
is no longer needed, and there is also vim.tbl_extend() that can be used
to add an environment variable to a job anyway.
Also, make a shallow copy of opts.env in setup_child_nvim(), as mutating
the opts.env passed in may mask problems in other tests.
(cherry picked from commit f876fd906e)
Today there is a constraint that these arguments to the enable filter be
mutually exclusive, but I do not know why such a constraint exists (it
is perfectly reasonable to want to enable a capabilility for just one
buffer and just one client).

Problem: A wrapped command line and screen width may be redrawn
repeatedly after calls to `redrawstatus` from lua.
Solution: redrawcmd() redraws the command line, but msg_clr_eos() may
invalidate cmdline_was_last_drawn during the redraw process.
Restore cmdline_was_last_drawn when redrawcmd() completes.

Problem:
:Man does not syntax highlight codeblocks (injected language).
Analysis:
init_pager() swapped pcall(parse_ref, ref) return values order, so
vim.b.man_sect was set to the manpage name instead of the section
number, so C syntax highlighting did not load.
Solution:
Swap the calls.
(cherry picked from commit 67b3cceaa7)
Problem: No message kind and multiple events for :recover and
(non-prompt) swapfile attention messages.
Solution: Assign these the "list_cmd" and "wmsg" kind.
Problem: The "Scanning:" completion, bufwrite, and indent (there may be
more) messages which indicate progress can use the "progress" kind
for their msg_show event. Indent message does not have a kind.
Solution: Emit these messages with the "progress" kind. Set the message id
to the replaced kind so that a UI knows to replace it (and to provide
a migration path in case a UI was distinguishing these messages for
whatever reason).
Problem: The refactor to use Capability left around some cruft and
semi-broken configuration for debounce.
Solution: Clean up now-unnecessary helper methods and simplify
deprecated ones to pass through to the non-deprecated ones. `debounce`
now defaults to 200 for all buffers but is overridable via the
deprecated start() method, which continues to take the max value
specified for any client attached to the buffer.
If we wish to expose changing the debounce in a non-deprecated way, we
will need to consider a "configuration" function, or even a bespoke
method to set the debounce time on the main metaclass (or provide
options to override for a particular buffer). General configuration of
specific LSP features is an as-of-yet unsolved problem.

Problem:
A colored (guisp) underline showing through a 'winblend' float
lost its special color and followed the foreground instead.
Solution:
In the blend-through case, blend the underline's special color
only when the cell below sets sp explicitly; otherwise clear it.

close#38987
(cherry picked from commit ebc69b387c)
Problem:
All (tested by me) terminals (xterm, st, ghostty, vte, foot, wezterm, konsole) do support `\x1b[0 q` as "reset cursor to default", but at least konsole and wezterm only understands `\x1b[0 q` as "reset to default", but have different behaviour on `\x1b[ q` (konsole sets "steady block", and wezterm does nothing (do not change cursor shape).
Solution:
Use `\x1b[0 q` would be more widely compatible "reset" sequence than `\x1b[ q`
P.S. actually, `xterm`, `ghostty` and `st` (with default config.h) sets "steady block" for both sequence, but still here `[0` behaves the same as `[`

`huntype` parses the address column by repeatedly left-shifting
`want_off` (a signed `long`) by 4 bits per hex digit. After 16 hex
digits the value occupies all 64 bits; the next shift moves a non-zero
bit into the sign bit -- signed overflow, i.e. undefined behavior.
This happens on the Zig build because it enables UBSAN. The bug was
pre-existing, but 966e7a98f5 added a test that exercises it.
Solution
Shift through `unsigned long` and cast back to `long`, making the
overflow well-defined wrap-around.

feat(lsp): use LspNotify for semantic tokens
Problem: The semantic token module is using its own debounce timer for
the buffer on_lines event. If its internal debounce is shorter than the
changetracking module's debounce, it's possible for semantic token
requests to fire for changed buffers before the textDocument/didChange
notification is sent to the server.
Solution: Trigger semantic token requests from the LspNotify autocmd
when the method is the didChange or didOpen notifications, which
enforces a strict happens-before relationship for the sync change
notification followed by a semantic token request.
Note: There is still an internal debounce mechanism in the semantic
token module to handle other debouncing needs specific to its
functionality, such as debouncing server refresh notifications and
handling WinScrolled events when using range requests.

Problem:
A text edit positioned entirely past the last buffer line, with
newText ending in a newline, leaves a stray blank line: the
past-the-end path appends the trailing empty fragment produced by
vim.split() and does not set has_eol_text_edit, so the end-of-buffer
cleanup is skipped. Formatting servers emit such edits whenever
formatting moves text to the end of a document.
Regression from ec94014cd1 (#20137), which split the past-the-end
fast path off the clamp path that sets the flag.
Solution:
Set has_eol_text_edit in the past-the-end path, like the adjacent
path that clamps end_row.

Problem:
When a server sends workspace/codeLens/refresh while an automatic codelens
request is already scheduled, Nvim ignores the server refresh. This can leave
rendered codelens text stale until another buffer edit triggers a new request.
Solution:
Cancel the pending automatic request and send the server-requested refresh
immediately. This preserves request coalescing while giving explicit server
refreshes priority.

Problem:
Various out-of-bounds writes inherited from vim (examples assume MAXPATHL==4096):
- truncated item groups where minwid>maxwid:
nvim --clean +"set stl=%<%{%repeat('x',4096-11)%}%50.5(12🙂345%)"
leads to fillchars spilling over the end of the group/buffer while trying to
compensate for truncating at a multicell character because minwid<=maxwid is assumed
- left-aligned item groups with multi-byte fillchar:
nvim --clean +"set fillchars+=stl:∙ stl=%<%{%repeat('x',4096-3)%}%-2(X%)"
wrongly leads to padding at the end of the statusline and `out_p-out==4097`
because the bounds check assumes a 1-byte fillchar
- right-aligned item groups with 1-byte fillchar:
nvim --clean +"set stl=%<%{%repeat('x',4096-4)%}%4(XY%)"
leads to "YX" instead of "XY" at the end of the statusline
because `memmove` is done before adjusting the offset
- right-aligned item groups with multi-byte fillchar:
nvim --clean +"set fillchars+=stl:∙ stl=%5(X%)"
leads to "∙∙∙∙<e2>", i.e. the fillchar is being written over the group contents
and eventually being overwritten itself at the second byte with the final NUL,
because the padding counter assumes a 1-byte fillchar; to crash Neovim,
nvim --clean +"set fillchars+=stl:∙ stl=%<%{%repeat('x',4096-149)%}%50(X%)"
Solution:
Clearer variable names and no recycling of variables for different purposes.
(cherry picked from commit e36659c82f)
Problem:
Flickering may occur when paging up/down in big files, as ranges for semantic
tokens are requested. This happens with LSP servers like gopls which return
"/full" semantic tokens if the file is too big, where we fall back to
viewport-range token retrievals.
Solution:
Broaden the requested ranges to one viewport of "overscan" on each side plus
some padding if possible:
(viewport_topline - viewport_height)..(viewport_botline + viewport_height)
(cherry picked from commit 3ed78daf83)
Problem:
`foldcolumn` is empty for virtual lines above the start of a nested

Problem:
`nvim -u NONE -d <(xxd one) <(xxd two)` has weird behavior.
Process substitution `<(...)` is a pipe and not a seekable file.
Test case:
cat /dev/random | head -c 10240 > one
cp one two
cat /dev/random | head -c 10240 >> two
nvim -u NONE -d <(xxd one) <(xxd two)
Solution:
Workaround the issue by skipping `nvim.difftool` if the 2 args are not
directories; fall-through to the builtin diff handling.

Problem:
stdpath() may return a DOS 8.3 "shortened" filename, because Windows
truncates some long usernames into `6ch~N` names. Then features such
as `nvim_get_runtime_file` fail to find the file.
Analysis:
When expanding an 8.3 filename path like `C:/Users/ADMINI~1/AppData/*`,
we treat `~` as a special character and first check whether a directory
named `ADMINI~1` exists under `Users`. Since no such directory actually
exists, the expansion fails.
Solution:
Treat `~` as a literal character in `do_path_expand`. Since the `~/`
case is already handled in `gen_expand_wildcards`, any remaining `~` is
just a literal character and will later be escaped to `\~` by
`file_pat_to_reg_pat` if needed.
(cherry picked from commit 7bf2ab4b87)
Problem:
When `vim.hl.range(0, …, { timeout = N })` is called, the deferred
`range_hl_clear` captures `buf=0`, which resolves to an arbitrary
"current buffer" at timeout. This may cause a stale highlight that never
gets cleared.
Solution:
Resolve `buf=0` explicitly, before `range_hl_clear` captures it.
(cherry picked from commit ec7dab077b)
Builds with -DNDEBUG do not contain the compilation string, so the test
will fail even if nvim is built with unibilium.
Similarly, zig builds only report "Compilation: TODO", so they also fail
the test even when build with unibilium
Detect both scenarios and skip the test, rather than failing it.

Problem: tests: Test_backupskip() may read from $HOME
Solution: Set $HOME to an empty value, use --clean
(D Ben Knoble)
Even though we unset HOME, we can see via scriptnames that user files
are still sourced! One of my installed plugins warns when not compiled
with +python3, so this test has a "press Enter" prompt.
Use `--clean` like most other GetVimProg()'s do to fix it. Some tests
use `system()` instead, but that turns this test into a failure rather
than passing; I'm not sure why other tests don't suffer from this.
To prove to ourselves, we can use code like this:
diff --git i/src/testdir/test_options.vim w/src/testdir/test_options.vim
index a408e20e1..044364a54 100644

Here, that causes "foo" to include a bunch of files under ~/.vim. I'm

Let's do that in addition since unsetting HOME isn't quite enough.

(cherry picked from commit 0039a13fe4)
Problem:
Currently, only some filesystems (Btrfs, ext2, ext3, ext4) have full
support of accessing the `dirent` entry-type. On other filesystems,
`uv.fs_scandir_next` may return `nil` for an existing but unsupported
entry-type.
This means consumers (such as `fs.dir()`), cannot know if `nil` means
"non-existent" or "unsupported".
Solution:
Fall back to `uv.fs_lstat` when `etype` is `nil`; return "unknown" if it
fails.

Problem: completion: cannot complete user cmd :K with 'ignorecase'
(rendcrx)
Solution: Skip the short-circuit when 'ignorecase' is set
(Yasuhiro Matsumoto)
The set_cmd_index() short-circuit for the :k command treats ":k<X>" as
":k {X}" (mark argument), which makes ":kz<Tab>" never reach the
command-name expansion path. With 'ignorecase' the same prefix on other
letters (":gz<Tab>") completes a user command like :Gz, so the result is
inconsistent. Skip the short-circuit when 'ignorecase' is set; default
behaviour is preserved so the existing :k tests still pass.
