Problem:
on_attach() calls refresh(), but there is no guarantee the attached
buffer is the current buffer. This can make linked editing request
handling assume the wrong window.
Solution:
Call refresh() only if the current buffer is attached. This keeps the
initial highlighting behavior while avoiding making incorrect request.

Problem:
LSP hover erroneously drops blank lines before a 4-space-indented
codeblock, which is not valid Markdown. This causes incorrect parsing
and wrong display.
Solution:
Fix `split_lines` so that it doesn't drop the blank line just before
a 4-space-indented codeblock.

Problem
The current list of properties for inlay hint resolve support includes a
non-existent "location". This field should be "label.location" according
to the specification. Tooltips and commands for inlay hint "parts"
aren't advertised as being resolvable.
Solution
Remove "location" and add "label.location", "label.tooltip", and
"label.command".

fix(lsp): use LspNotify for document_color #40571
Problem: The document_color lsp module was already using the capability
framework but was still using raw buffer events to handle requests and
reloading. This means that every keystroke was sending a document_color
request to the server since there was no debounce in the raw handlers.
Solution: Switch to using LspNotify autocmd events. LspNotify fires just
after new document versions are synced with the server and provides a
built in debounce mechanism for changes. It also provides the signal for
when the current state should be cleared (didClose). The detach part is
already handled by the capability framework.
Fixes#39785
(cherry picked from commit 29db6ce84c)
Problem: A previous refactor removed the BufWinEnter autocmd that
initiated a token request. When an LSP server sends a refresh
notification, then buffers that aren't shown in any window lost their
only trigger to request new tokens.
Solution: Add the BufWinEnter autocmd back which simply requests tokens
for all clients attached to the buffer.
Some servers register `workspace/didChangeWatchedFiles` watchers for URI
schemes that cannot be watched locally. Skipping the unsupported glob
and keep the rest of the registration batch active.
(cherry picked from commit 4d9e5acfb5)
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.

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).
(cherry picked from commit ed267268b8)
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.
(cherry picked from commit 859790e244)
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:
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)

feat(ui): vim.ui.input(opts.scope) #39570
Problem: There is no way for a `vim.ui.input` caller to indicate for
which scope the input is. As in "This input is for something at cursor
scope". This information can be useful for `vim.ui.input`
implementation to tweak its behavior and presentation:
- Show different floating window depending on the scope. For example:
- Near cursor for "cursor" scope.
- At line start for "line" scope.
- In window corner for "buffer" and "window" scopes.
- In whole editor corner for "tabpage", "editor", "project" scopes.
- Navigate through history only for inputs with the same scope.
Solution: Document new `opts.scope` for `vim.ui.input`. Use it in the
codebase.
Problem:
Linter missed backtick and double-quote keynames in the quasi-keyset of
the `nvim_create_user_command` docstring.
Solution:
Update the linter to check backtick-surrounded and quote-surrounded key
names.
Problem:
LSP clients previously did not handle dynamic registration for off-spec methods
Solution:
Update the client logic to assume support for dynamic registration when
the method is unknown. Adjust the registration provider fallback and
enhance tests to verify correct behaviour for unknown methods and their
registration options. This improves compatibility with servers using
custom dynamic registrations.

docs: update instructions for debugging LSP
Previously, it was suggested to set:
vim.lsp.log.set_format_func(vim.inspect)
This made sense before f72c13341a, when
`format_func` was called once per argument being logged, but since that
commit it's called with the log level followed by the other args, so the
suggested setting would call `vim.inspect(log_level, ....)` which would
just print the human readable name of the current log level and no other
details, for example with this set I saw in my logs:
"DEBUG""DEBUG""DEBUG""DEBUG"
Instead just rely on the default formatter, which will:
> ... log the level, date, source and line number of the
caller, followed by the arguments.

fix(lsp): send didClose, didOpen when languageId changes
Problem:
If a buffer's filetype changes after the LSP client has already
attached (e.g. from json to jsonc via a modeline), but the client
supports both filetypes, it stays attached. It does not notify the
server of the new languageId, causing the server to incorrectly process
the file using the old languageId.
Solution:
Save the languageId used during textDocument/didOpen, and send
textDocument/didClose + textDocument/didOpen when buffer's languageId
changed.
Lsp spec:
0003fb53f1/_specifications/lsp/3.18/textDocument/didOpen.md (L5)
> If the language id of a document changes, the client
> needs to send a textDocument/didClose to the server followed by a
> textDocument/didOpen with the new language id if the server handles
> the new language id as well.

(cherry picked from commit 775c7d1b53)
Problem:
The LSP client incorrectly checks for server capabilities when determining
support for self-mapped methods (e.g., 'shutdown'), which do not have
corresponding capabilities in the server's response. This leads to false
negatives when checking if such methods are supported.
This was handled correctly for dynamic registrations, but not for static.
Methods such as 'shutdown', do not have a related server capability and should
be assumed to be supported.
Solution:
Update the `supports_method` logic to always return true for self-mapped
methods.

Problem:
LSP spec allows response message to have a null request-id.
This may happen when for example client sends unparseable request.
https://github.com/microsoft/language-server-protocol/issues/196
Solution:
Guard the server response branches against id=vim.NIL (json null),
and handle error responses with null id by logging a warning
and dispatching on error.
Problem:
CI (ubuntu asan, ubuntu tsan, windows) reports `uv_loop_close()
hang?` from the two new null-id response tests. The leaked
handle is the server-side accepted TCP socket created inside
`server:listen` callback. The tests closed only the listener
but not the accepted socket, so libuv could not finish shutting
down the loop and each test session took ~2s extra to exit.
Solution:
Hoist the accepted socket to the outer `exec_lua` scope and
close it at teardown before closing the listener. The close
runs synchronously inside `exec_lua`, so the loop has time to
dispose the handle before the session exits.
* test(lsp): close accepted socket on read-loop exit/error
Match the precedent in the handler test ("handler can return
false as response") and the shared `_create_tcp_server` helper
in `test/functional/plugin/lsp/testutil.lua`: close the
accepted socket from inside the `create_read_loop` exit/error
callbacks. The teardown close added in the previous commit
remains as belt-and-suspenders, so the socket is disposed
whether the server goes away first or the client does.
Problem:
After on_refresh() sends a textDocument/codeLens request, the buffer may
be deleted before the response arrives. The response callback then tries
to redraw that deleted buffer and raises Invalid buffer id error.
Solution:
Check buffer validity before redrawing.

passes through `gen_eval_files.lua` and `gen_vimdoc.lua`. And that's
a good thing.

Some variables use the wrong type (ClientToServer instead of ServerToClient)
and some use vaguer types that could be more strict.

Problem:
Since 2f6d1d3c88, `apply_text_edits`
unconditionally sets `buflisted=true`, causing spurious BufDelete events
if plugins restore the original 'buflisted' state on unlisted buffers:
65ef6cec1c/src/nvim/option.c (L2159-L2169)
Solution:
- Don't set 'buflisted' in `apply_text_edits`. Set it more narrowly, in
`apply_workspace_edit` where the semantics requires affected buffers
to be visible to the user.
- Also skip setting 'buflisted' if it would not be changed, to avoid
redundant `OptionSet` events.

Problem:
`:checkhealth vim.lsp` validates configured filetypes against

This causes false warnings in `:checkhealth vim.lsp` for configured
