Ref #6645
Problem:
When a window is resized it takes space from the window right/below first,
and only falls back to the window left/above when there is no more room.
Sometimes a user wants the space to come from a specific direction.
Solution:
Add nvim_win_resize(win, width, height, {anchor}) which resizes a window
with a choosable anchor edge, letting a window grow leftwards or upwards
by taking space from the window to the left or above first. The default
anchor reproduces nvim_win_set_width()/nvim_win_set_height().
Problem: An autocommand that redraws may do so while curwin is
temporarily set for the autocommand scope. This can result in
flickering or unexpected state with UI components (statusline,
winbar, decor providers...) that depend on the current window.
Current workaround for statusline and winbar specifically
delays the redraw, which can itself be unexpected for the
autocommand.
Solution: If redrawing happens with a temporary autocmd current window,
temporarily restore the current window while redrawing.
Problem: Attach-time terminal probes cannot distinguish responses from
different attached UIs.
Solution: Identify the UI by RPC channel id in `TermResponse` and make
`vim.tty.request()` filter responses by channel.
Problem: `nvim_exec_autocmds({buf=...})` may temporarily switch curwin/curbuf
through `aucmd_prepbuf()`. Requested statuslines/winbars before
`aucmd_restbuf()` may erroneously see the target window as current.
Solution: Track `aucmd_prepbuf()` window-switch depth and leave statusline/winbar
redraws marked dirty until the original window is restored.
Problem: When the cursor line has concealed text before the start of the
completion, the insert-mode completion popup is drawn at the wrong
screen column and the cursor no longer lines up with the completed
text.
Solution: Record the concealed width before the cursor on its screen line in
a new `win_T` field while `win_line()` draws it, subtract it in
`pum_display()` to place the menu over the visible text, and redraw
the cursor line so `win_line()` corrects the cursor too.

Problem: ':delete #' silently fails to update "# and clobbers "0.
Solution: Treat "# like "/, writable only with :let and setreg().

Problem: Clearing the screen doesn't clear the "last" virtual text.
Dupe counter virtual text is not increased beyond 1.
Solution: Clear "last" virtual text when clearing the screen.
Restore assignment lost in a previous commit.
Problem: Wrong dot-repeat when calling complete() while filtering
Ctrl-N completion.
Solution: Also check compl_started for whether completion is active.

Problem: Terminal background and truecolor detection runs only at startup,
gated on a UI being attached. A headless server has no UI then, so
`'background'` and `'termguicolors'` are never detected and remote
UIs ignore the terminal's theme.
Solution: Also (re)detect on UIEnter. The most recently attached terminal
wins; an explicit user value is preserved.
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.
Fixes#36257
Problem:
- Current 'statuscolumn' click label caveat is restrictive.
- v:virtnum is not unique to a line if it has both above and
below virtual lines.
- 'statuscolumn' click handler may expect v:virt/lnum to be set.
Solution:
- Store per-row click definitions for the statuscolumn in a
(nested line/virt number) map.
- Implement strategy that gives each 'statuscolumn' row a unique
v:virtnum.
- Set v:virt/lnum when determining which line is clicked.
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.
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:
Can't open swapfile when using a device path starting with `//?/`,
because `?` is a reserved char on Widnows.
Solution:
For device UNC paths, replace `//?/UNC/` and `//./UNC/` with `//`.
For other device paths, just strip their prefix (i.e. `//?/`, `//./`).
This aligns swapfile naming for device paths with regular UNC and DOS
paths.

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.
Problem:
an empty `{ isIncomplete = true, items = {} }` ends completion
instead of requerying.
Solution:
keep isIncomplete on empty lists and retrigger on keypress while incomplete.
Reset on <C-e> so it doesn't immediately re-query.
Problem: a font set via nvim_set_hl is lost or corrupted with font-only groups,
attribute combining, and update=true, and is dropped on any attr-table rebuild.
nvim__inspect_cell also frees the font name while a returned dict still borrows it.
Solution: register font-only groups, carry font through hl_combine_attr, inherit
it on update, and persist sg_font so a rebuild can restore it. Keep interned font
names across a rebuild instead of clearing them. Add the missing font field to
get_hl_info.

Problem: vim.diagnostic.Opts.VirtualLines.current_line and
vim.diagnostic.Opts.VirtualText.current_line cause redraw
on every CursorMoved event that makes the text jump
uncomfortably with rapid cursor movement.
Solution: `current_line` state is applied only on CursorHold,
while still being cleared on CursorMoved making it so that
until the cursor has stopped on a line, its diagnostic
looks like cursor is not on the line preventing flicker.
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:
On Windows and macOS, entries in `oldfiles` may differ only in case,
but actually refer to the same file.
Solution:
Previously, deduplication used `Set_cstr_t`. We can add a similar `Set_path_t`
that performs path-aware comparisons, ignoring case differences. On Windows, it
could also ignore path separator differences, and treat `C:\foo` and `\foo` as
the same path when the current drive is `C:`.

Problem:
On some non-US keyboards, like Estonian/Swedish/etc, widely used []
characters in vim are hard to type. One way to overcome this is to use langmap
option to map accented characters, that are in the same place as [] on US
keyboards to []. Unfortunately this does not work currently in neovim, it
cannot map multibyte characters via langmap.
Solution:
The fix iterates over characters in typeahead and key buffers, instead of bytes,
in getchar.c handle_mapping(). It does not handle macros though, these tests are
still failing when turned on.

Problem:
Any random ftplugin or other autocmd, can throw an error when
`:checktime` reloads a buffer. This causes a trace which makes it look
like an issue with `autoread.lua`.

Solution:
Use pcall() and surface the error via nvim_echo.
Problem:
Old 'autoread' only did `:checktime` on focus-change and shell (":!")
commands, and only for non-hidden buffers. Since 'autoread' is now
driven by OS filewatcher events, buffers are updated much more eagerly.
This should be surfaced to the user somehow, either via a carefully
placed notification, or a minimal UI indicator.
A "notification" would be noisy, unless it is conditional on specific
circumstances (e.g. when "many" buffers are updated).
Solution:
Use the existing 'busy' buffer-local option as a subtle hint about
activity.
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: Running `vim.filetype.match()` when current working directory
was removed from disk throws a `vim.fs.abspath` assertion error.
However, the matching might still be possible without trying to match
against full path (like if it is a known extension).
Solution: Safely compute absolute path and ignore it if it errors.
Problem: Clicking on a "below" virtual line interacts with the line
it is attached to for decor/drawing purposes, rather than
the line the extmark is placed at.
Solution: Account for "below" virtual lines when computing mouse line number.
Problem:
After 400f247397 the undotree test became flaky.
It seems to be caused by some kind of race condition where an entry in the undotree is not added when a change in the buffer happens (adding a bunch of sleep around buffer-change operations seems to fix the issue).
Solution:
Disable autoread plugin in undotree test.
Problem: Diagnostic virtual lines are hardcoded with "scroll" for
virt_lines_overflow option.
Solution: Add a `overflow` option to `virtual_lines` config
to support "wrap", "scroll", "trunc", and "auto".
Problem:
The 'autoread' option only checks for file changes reactively — on
FocusGained, :checktime, CmdlineEnter, etc. — by polling timestamps.
External changes are not detected until the user interacts with Neovim.
Solution:
Add a core module (runtime/lua/nvim/autoread.lua) enabled from
runtime/plugin/autoread.lua that watches each buffer's file using
vim._watch.watch() (libuv fs_event). On change detection it calls
:checktime, which invokes the existing buf_check_timestamp() logic
for reload/prompt handling. Watchers are managed via autocmds tied
to buffer lifecycle events and respect the 'autoread' option (global
and buffer-local).
Problem:
stdpath() may return a DOS 8.3 "shortened" filename, because Windows
truncates long usernames into `6ch~N` names in `TEMP/TMP` env vars.
We don't want to "leak" them into Nvim.
Solution:
For "run", pass `true` to `vim_FullName` to expand 8.3 filenames.
For "cache", call `os_realpath` to expand 8.3 filenames.

Problem:
Listing individual "skipped" notices for each non-actionable or
NVIM_TEST_INTEG test is noisy and makes the "skipped" list overwhelming
and less meaningful.
Solution:
- Mark non-actionable tests with "N/A".
- Report NVIM_TEST_INTEG tests as a separate 1-line summary.
