**Problem:** An erroneous query in the treesitter highlighter gives a
deluge of errors that makes the editor almost unusable.
**Solution:** Detach the highlighter after an error is detected, so that
it only gets displayed once (per highlighter instance).

Problem:
Some language servers (e.g., rust-analyzer, texlab) are desynced when
the user deletes the entire contents of the buffer. This is due to the
discrepancy between how nvim computes diff and how nvim treats empty
buffer.
* diff: If the buffer became empty, then the diff includes the last
line's eol.
* empty buffer: Even if the buffer is empty, nvim regards it as having
a single empty line with eol.
Solution:
Add special case for diff computation when the buffer becomes empty so
that it does not include the eol of the last line.
Problem: There is no check for buffer validity before processing
semantic tokens response. This can lead to `Invalid buffer id` error
if processing request takes a long time and the buffer is wiped out.
For example, this can happen after by accident navigating to a buffer
from different project which leads to first loading project's
workspace and *then* processing semantic tokens. During that time
a buffer can be wiped out, as navigation to it was by accident.
Solution: Add extra check for buffer validity before processing semantic
tokens response.

Problem: autocmd to refresh folds always uses the current buffer if the
option type is local. However, the current buffer may not have a parser,
and thus the assert that checks for a parser could fail.
Solution: check if the foldinfo contains the buffer, and only refresh if
so.
Problem:
Exiting the insert mode with ctrl-c does not trigger InsertLeave
autocmd. This may lead to nil error in treesitter foldexpr.
Solution:
Check nil. Folds still can be stale after exiting the insert mode with
ctrl-c, but it will be eventually updated correctly.
An alternative solution would be to ensure that exiting the insert mode
always triggers do_foldupdate. This can be done either by "fixing"
ctrl-c or with on_key callback that checks ctrl-c (nvim-cmp does this).
Problem:
`o`-ing on a folded line opens the fold, because the new line gets the
fold level from the above line (level '='), which extends the fold to
the new line. `O` has a similar problem when run on the line below a
fold.
Solution:
Use -1 for the added line to get the lower level from the above/below
line.
Problem:
The floating window for hover and signature help always cuts off a few lines,
because the `_make_floating_popup_size` function counts empty lines as having
zero height.
Solution:
Ensure the height is at least 1.
(cherry picked from commit a4f575abd8)
The maximum signed value on 32-bit systems is 2 ^ 31 - 1. When using 2 ^ 31 for
the default timeout, the value would overflow on such systems resulting in
a negative value, which caused a stack trace when calling wait() without
a timeout.
(cherry picked from commit 4e130c1ee4)
Problem:
Diagnostics and inlay hints can be expensive to calculate, and we
shouldn't stack them as this can cause noticeable lag.
Solution:
Check for duplicate inflight requests and cancel them before issuing a new one.
This ensures that only the latest request is processed, improving
performance and preventing potential conflicts.
**Problem:**
The brackets in the RFC2732 regular expression are currently unescaped,
causing them to be misinterpreted as special characters denoting
character groups rather than as literal characters.
**Solution:**
Escape the brackets.
Fix#31270
(cherry picked from commit 442d338cb5)
Problem: In an autocommand Lua callback whether `args.file` is expanded
depends on whether `expand('<afile>')` has been called.
Solution: Always use the unexpanded file name for `args.file`.
Related to #31306 and vim/vim#16106. This doesn't provide `sfname`, but
at least makes `args.file` have a consistent value.
Problem: It is not obvious if a treesitter highlight priority shown in
`:Inspect` is higher or lower than the default.
Solution: Also print default priority (`vim.hl.priorities.treesitter`).
Add padding for better readability.
(cherry picked from commit b52ffd0a59)
Problem: `:Inspect` does not show priority for treesitter highlights,
leading to confusion why sometimes earlier highlights override later
highlights.
Solution: Also print priority metadata if set.
(cherry picked from commit 9c278af7cc)
Problem:
Previously the index was only checked against the UTF8 length. This
could cause unexpected behaviours for strings containing multibyte chars
Solution:
Check indicies correctly against their max value before returning the
fallback length
(cherry picked from commit 80e37aa533)
Problem: For :InspectTree, indent size (`&shiftwidth`) for the tree
viewer may be incorrect.
This is because the tree viewer buffer with the filetype `query` does
not explicitly configures the tab size, which can mismatch with the
default indent size (2) assumed by TSTreeView's implementation.
Solution: Set shiftwidth to be the same as TSTreeViewOpts specifies,
which defaults to 2.
(cherry picked from commit 5331f87f61)
Problem:
Linematch used to use strchr to navigate a string, however strchr does
not supoprt embedded NULs.
Solution:
Use `mmfile_t` instead of `char *` in linematch and introduce `strnchr()`.
Also remove heap allocations from `matching_char_iwhite()`
Fixes: #30505
(cherry picked from commit c65646c247)
Problem:
EditQuery shows swapfile ATTENTION, but this buffer is not intended for
preservation (and the dialog breaks the UX).
Solution:
Set 'noswapfile' on the buffer before renaming it.
(cherry picked from commit b63cd8cbae)
Problem:
fnamemodify with the :r flag will not strip extensions if the filename
starts with a ".". This means that files named ".in" could cause an
infinite loop.
Solution:
Add early return if the filename was not changed
(cherry picked from commit 032e024f8a)
fix(vim.fs): dirname() returns "." on mingw/msys2 #30480
Problem:
`vim.fs.dirname([[C:\User\XXX\AppData\Local]])` returns "." on
mingw/msys2.
Solution:
- Check for "mingw" when deciding `iswin`.
- Use `has("win32")` where possible, it works in "fast" contexts since
b02eeb6a72.
**Problem:** Top-level anonymous nodes are not being checked by the
query linter
**Solution:** Check them by adding them to the top-level query
This commit also moves a table construction out of the match iterator so
it is run less frequently.
Problem:
The LSP omnifunc can insert nil bytes, which when read in other places
(like semantic token) could cause an error:
semantic_tokens.lua:304: Vim:E976: Using a Blob as a String
Solution:
Use `#line` instead of `vim.fn.strlen(line)`. Both return UTF-8 bytes
but the latter can't handle nil bytes.
Completion candidates can currently insert nil bytes, if other parts of
Alternative fix to https://github.com/neovim/neovim/pull/30359
Note that https://github.com/neovim/neovim/pull/30315 will avoid the
insertion of nil bytes from the LSP omnifunc, but the change of this PR
can more easily be backported.

`path2name()` function doesn't process `'pluginname/health/init.lua'` correctly. Instead of retruning `'pluginname'` it returns `'pluginname.health'`
(cherry picked from commit 237d2aef4d)
Problem:
str_utfindex_enc could return an error if the index was longer than the
line length. This was handled in each of the calls to it individually
Solution:
* Fix the call at the source level so that if the index is higher than
the line length, utf length is returned
(cherry picked from commit f279d1ae33)
Problem:
str_byteindex_enc could return an error if the index was longer than the
lline length. This was handled in each of the calls to it individually
Solution:
* Fix the call at the source level so that if the index is higher than
the line length, line length is returned as per LSP specification
* Remove pcalls on str_byteindex_enc calls. No longer needed now that
str_byteindex_enc has a bounds check.
Problem: When preparing the parameters for a code actions LSP request,
the code set `context.diagnostics` when processing the first LSP client,
and then reused those `context.diagnostics` for subsequent LSP clients.
This meant that the second and next LSP clients got diagnostics that
did not originate from them, and they did not get the diagnostics that
they sent.
Solution: Avoid setting `context.diagnostics` (which is referenced by
all clients). Instead, set `params.context.diagnostics` directly, which
is specific to a single client.

Problem:
If there are errors in the last line of a buffer, something like `Gdk` or
`G2k3J` will produce an error (at least with `lua_ls`):
Error executing vim.schedule lua callback:
.../neovim/share/nvim/runtime/lua/vim/diagnostic.lua:1446: Invalid 'line': out of range
Solution:
Only set extmarks if the target buffer line still exists
(cherry picked from commit e5e81262af)
`buf.code_action` always included diagnostics on a given line from all
clients. Servers should only receive diagnostics they published, and in
the exact same format they sent it.
Should fix https://github.com/neovim/neovim/issues/29500
(cherry picked from commit 720b309c78)
Problem:
When there are multiple inlay hints present at the same position, they
should be rendered in the order they are received in the response from
LSP as per the LSP spec. Currently, this is not respected.
Solution:
Gather all hints for a given position, and then set it in a single
extmark call instead of multiple set_extmark calls. This leads to fewer
extmark calls and correct inlay hints being rendered.
**Problem:** A query file for something like `html_tags` will not be
given html node completion
**Solution:** Check for parser aliases before offering completions
