44ea4cfcc4 test(tui_spec): remove unnecessary job_opts variable (#40334)
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.

5ff4e147d0 fix(cmdline): avoid redraw loop after wrapped line #40240
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.

0b134d8b23 fix(messages): message kind for :recover and swapfile attention #39444
Problem:  No message kind and multiple events for :recover and
          (non-prompt) swapfile attention messages.
Solution: Assign these the "list_cmd" and "wmsg" kind.

527c7c8c6b fix(messages): "progress" kind for busy messages #39280
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).

fec4045601 backport: feat(lsp): clean up semantic token initialization and debounce #40266
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.

749126de08 fix(highlight): keep guisp underline color in float with 'winblend' #40283
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.

55205b3231 backport: feat(lsp): use LspNotify for semantic tokens (#40242)
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.

dc6a9170eb backport: fix(lsp): trailing blank line when edit inserts past end of buffer (#40176)
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.

ecda67662f backport fix(lsp): refresh codelens despite pending debounce #40177
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.

83d9b9afca fix(statusline): prevent various buffer overflows with item groups #40219
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.

585c93204f fix(path): nvim_get_runtime_file fails on DOS 8.3 filename #40144
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.

be4e7cfd6a fix(vim.hl): range(0,…) highlight not cleared after buffer-switch #40130
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.

3a3405d964 fix(test): only test for unibilium if a valid compilation string exists
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.

964e797fdf vim-patch:9.2.0395: tests: Test_backupskip() may read from $HOME (#39417)
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
not sure why this happens, but lets paper over it for the test.

We can also tell that (orthogonal to --clean) setting HOME='' works too.
Let's do that in addition since unsetting HOME isn't quite enough.

b9d39f5bb2 fix(vim.fs): fs.dir() may return nil "type" on some filesystems #39749
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.

b490fba786 fix(mouse): mouse=n should not adjust visual selection
Problem:

When mouse=n is set
  - Dragging the mouse enters visual mode, and then stops listening for
    mouse events.
  - Double/Triple/Quad clicking performs selections.
  - Clicking in visual mode moves the cursor (though not through the TUI).

Solution:

Explicitly gate mouse actions that affect visual mode with a check for
MOUSE_VISUAL. This matches the behavior described in :help mouse.

> If enabled for "v" (Visual mode) then double-click selects word-wise,
> triple-click makes it line-wise, and quadruple-click makes it
> rectangular block-wise.

781c43ea05 fix(api): adjust Visual position after nvim_buf_set_text #30690
Problem:
Visual selection could end up in the wrong place after
nvim_buf_set_text or nvim_buf_set_lines. In some delete cases,
Visual.lnum was already clamped before the line shift happened, so the
adjustment got skipped.

Solution:
Split fix_cursor_cols into reusable fix_pos_col logic and reuse it
for Visual updates. Also adjust Visual.lnum before changed_lines so
the shift uses the original position before final clamping.

5b8268356a fix(api): don't update 'title' when renaming non-curbuf #39743
Problem:  'title' is updated when changing the name of a non-current
          buffer with nvim_buf_set_name().
Solution: Set RedrawingDisabled when renaming the buffer.

d725ead5ec fix(messages): reset redirection message column after :echon #39472
Problem:  Message redirection column for captured output is not reset
          after :echon since (4260f73, e63346df).

Solution: Ensure msg_ext_append is set before the kind with :echon.

647b6be489 vim-patch:9.2.0461: Corrupted undofile causes use-after-free (#39707)
Problem:  The four pointer-resolution loops in u_read_undo() lack
          an i != j guard, so a header whose uh_next.seq equals
          its own uh_seq resolves uh_next.ptr to itself.  On
          buffer close, u_freeheader() sees uhp->uh_next.ptr !=
          NULL and skips updating b_u_oldhead, so u_blockfree()
          dereferences the freed header on the next iteration.
          The same pattern applies to uh_prev, uh_alt_next and
          uh_alt_prev.  A crafted .un~ file in the same directory
          as a text file can trigger the use-after-free and
          subsequent double-free when the buffer is closed.
          (Daniel Cervera)
Solution: Add an i != j guard to each of the four resolution
          loops, matching the guard already present in the
          duplicate-detection loop above.

79fd0b6655 fix(vim.range): empty ranges semantics vs regular ranges #39474
Problem:
- Empty ranges have different `<`, `<=`, `has` and `intersect` semantics compared to regular ranges.
- `to_inclusive_pos` assumes that the end position of a range is exclusive, which is not true for empty ranges

Solution:
Special case empty ranges in these operations.

2389cf2e39 fix(shell): preserve CR when :! outputs to binary-mode buffer #39558
Problem:
When `:!` writes shell output to a buffer, write_output() splits on `\r`, `\n`,
and `\r\n`, replacing the terminator byte with NUL. For a binary-mode buffer
this is wrong: `\r` should be preserved verbatim, not treated as a line
terminator. This wrong behavior causes a file like `\r\n` round-trips through
`:%!cat` to `\n`.

This was masked when 'shelltemp' was enabled, because output went through a temp
file and the regular file I/O path handled binary-mode correctly. Switching the
default to 'noshelltemp' exposed the bug, since output is now piped directly
into write_output().

Solution:
In `write_output()`, skip the `\r` and `\r\n` splits for a binary-mode buffer;
only split on `\n`.

b3cd33d029 backport feat(tui): restore 'ttyfast' to control tty requests (#39667)
feat(tui): restore 'ttyfast' to control tty requests

Problem:
When running nvim on a remote machine over SSH, if there is high ping,
then bg detection may not complete in time. This results in a warning
every time nvim is started. #38648

Solution:
Restore 'ttyfast' option and allow it to control whether or not bg
detection is performed. Because this is during startup and before any
user config or commands, we use the environment variable
`NVIM_NOTTYFAST` to allow disabling `ttyfast` during initialization.

03af1ec931 vim-patch:9.2.0450: [security]: heap buffer overflow in spellfile.c read_compound() (#39660)
Problem:  read_compound() in spellfile.c computes the size of the regex
          pattern buffer using signed-int arithmetic on the attacker
          controlled SN_COMPOUND sectionlen.  With sectionlen=0x40000008
          and UTF-8 encoding active the multiplication wraps to 27 while
          the per-byte loop writes up to ~1B bytes, overflowing the heap.
          Reachable when loading a crafted .spl file (e.g. via 'set spell'
          after a modeline sets 'spelllang').  The cp/ap/crp allocations
          have the same int + 1 overflow class (Daniel Cervera)
Solution: Use type size_t as buffer size and reject values larger than
          COMPOUND_MAX_LEN (100000).  Apply the same size_t treatment to
          the cp/ap/crp allocations.

dcf9e8a98e fix(treesitter): crash in ts_parser_delete after gc #39497
Problem:
parser_gc() calls ts_parser_delete() but leaves the userdata pointer
pointing to freed memory. If the GC finalizer runs at an unexpected time
(e.g. inside nvim_buf_get_lines #39411), a stale pointer could cause a crash.

Solution:
- NULL out `*ud` after ts_parser_delete() in parser_gc()
- Update parser_check() to handle NULL with a clear error message,
guarding all parser methods against UAF
