Problem:
`vim.lsp.buf.definition`/`vim.lsp.buf.declaration` use the same underlying code
via `get_locations`, whereas `vim.lsp.buf.reference` does not. This is because
`buf.reference` does not perform a jump when there is only one item.
Solution:
In #38510, I simplified the jump logic using `:cfirst`, so they can now share
code more easily. Additionally, this PR enables `buf.definition` to display the
corresponding qflist name.
Problem:
`:help dev-name-common` states that "buf" should be used instead of
"buffer" but there are cases where buffer is mentioned in the lua API.
Solution:
- Rename occurrences of "buffer" to "buf" for consistency with the
documentation.
- Support (but deprecate) "buffer" for backwards compatibility.

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: nvim_clear_autocmds() does not type check "event" correctly, and also
treats an empty array "event" like nil.
Solution: fix type checking. Treat empty array "event" as a no-op, like
nvim_exec_autocmds(). Add some extra tests.
Likewise the nil handling change may be considered breaking if anyone
(unintentionally) relied on that. It was also true that integer, function, etc.
"event"s would also be treated like nil!
Note that an empty string "event" is still an error, as that's must be an exact
match on an event name.
Problem: nvim_exec_autocmds() documentation incorrectly describes the default
for "pattern" as *, when it's actually the current file name (like :doautocmd).
Solution: correct it. Add a test.
Problem: in autocmd APIs, a non-nil "pattern" containing only empty
'sub'-patterns is silently treated as nil, causing the fallback value to be
unexpectedly used instead.
Solution: for nvim_create_autocmd(), raise a validation error (as no autocmds
would be created). For nvim_{exec,clear}_autocmds(), make it a no-op (as
matching no autocmds is not an error).
Problem:
The current LSP diagnostic implementation can't differ between a pull
diagnostic with no identifier and a set of diagnostics provided via push
diagnostics.
"Anonymous pull providers" are expected by the protocol https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#diagnosticOptions
, depending on how the capability was registered:
- Dynamic registrations have an identifier.
- Static registrations will not.
Solution:
Restore the `is_pull` argument removed in
https://github.com/neovim/neovim/pull/37938, keeping the identifier of
pull diagnostic collections.
Problem: vim.VersionRange had no __eq metamethod, so comparing 2 distinct
but same value instances always returned false. In vim.pack.add this caused
redundant lockfile rewrites, even when the resulting lockfile content was
unchanged.
Solution: Add __eq metamethod on vim.VersionRange
Problem:
`:checkhealth vim.lsp` validates configured filetypes against
`getcompletion('', 'filetype')`. This only reflects runtime support
files.
This causes false warnings in `:checkhealth vim.lsp` for configured
filetypes that are known to the Lua filetype registry, including
values added with `vim.filetype.add()` and built-in registry-only
filetypes.
Solution:
Build the healthcheck's known-filetype set from both
`getcompletion('', 'filetype')` and `vim.filetype.inspect()`.
Problem: When the 'ruler' is in the last line of the screen, it takes
local highlight definitions of the current window, tripping an
assert (since c1648cf8).
Solution: Don't use window-local highlight definitions when the ruler is
not part of a statusline.

Problem:
`vim.Range` and `vim.Pos` have signature mismatches on the docs of some functions.
Solution:
Split the "module" functions from the "class" functions (just like it's done in other modules like `vim.version`) and regenerate the docs.
the unix.vim file was probably accidentally ignored at some point.
An actual invokation of nvim-under-test would in practice look like
["/path/to/neovim/build/bin/nvim", "-u", "unix.vim", "-U", "NONE", "-i", "NONE", "--noplugin", "--headless", "-u", "NONE", "--cmd", "set shortmess-=F", "-S", "runtest.vim", "test_arabic.vim"]
but -u NONE cancels out the earlier -u unix.vim
By now, too many tests rely on specific behavior from "NONE", so copy in
the useful parts of unix.vim to the cmdline again. also, some tests
conflict with `directory=.` (or even `directory=Xtempswapdir`) so don't use that.
`-U NONE` is dead code in Nvim, remove it.
Problem: When Neovim is built with Zig, `:checkhealth` falsely reports
"Non-optimized debug build" for release builds. The extraction regex
stops at the first space, and the validation regex only lists CMake
build type names.
Solution: Fix the extraction regex to capture the full build type string
and add Zig optimization levels (ReleaseFast, ReleaseSafe, ReleaseSmall)
to the validation regex.

Problem: pum_col goes negative when item width + border exceeds screen.
Solution: account for border_width in pum_compute_horizontal_placement()
instead of adjusting pum_col after the fact
Problem:
On exit, rpc_free() is called when processing main_loop.events after
libuv calls close callbacks of the channel's stream. However, when there
are no child processes, these libuv callbacks are called in loop_close()
instead of proc_teardown(), and main_loop.events isn't processed after
loop_close(). As a result, calling remote_ui_disconnect() in rpc_free()
causes UILeave to depend on the presence of child processes.
Solution:
Always call remote_ui_disconnect() in rpc_close_event(), and remove the
call in rpc_free().
Problem: When emitting a msg_show event with the "empty" kind,
there may still be messages waiting to be emitted, which
are then dropped as a result of recursion protection.
Solution: Flush messages before emitting "empty" message show.
Problem: Undefined behavior when 'undodir' contains empty entry.
Solution: Don't try to remove trailing slashes from empty path. Also
don't remove a colon on Windows while at it.

Problem: 'inccommand' preview is not executed after setcmdline(),
and as a result cmdline_show event is emitted when redrawing
is not allowed (5b6477be).
Solution: Call command_line_changed() when ccline.cmdbuff_replaced is
set (by setcmdline()).
Problem: No way of inspecting the (user-added) filetype detection rules.
Solution: Add `vim.filetype.inspect()` returning copies of the internal
`extension`, `filename`, `pattern` tables. Due to the dynamic nature of
filetype detection, this will in general not allow getting the list of
known filetypes, but at least one can see if a given extension is known.
Problem:
We normally get the background color via continuous reporting. However,
if we were backgrounded while the light/dark mode changed, we won't have
received the report, and we'll have the wrong background color.
Without this change, if you background nvim, toggle the light/dark mode,
resume, and check `:set bg`, it will not match the current state.
Solution:
Query it on resume as well. (This requires separating the query from the
flush, to just do the query along with all the others, while waiting to
flush until we've set up uv.)
With this change, if you background nvim, toggle the light/dark mode,
resume, and check `:set bg`, it will have updated.
Problem: `buf` is optional even though its needed to perform conversions
and the ordering of `(buf, row, col)` is not consistent.
Solution: make `buf` mandatory on `vim.range` and `vim.pos` and enforce
the `buf, row, col` ordering
Problem: runtime(tar): some issues with lz4 support
Solution: Fix bugs (see below) (Aaron Burrow)
The tar plugin allows users to extract files from tar archives that are
compressed with lz4. But, tar#Extract() builds malformed extraction commands
for lz4-compressed tar archives. This commit fixes three issues in that code.
The first affects archives with a .tlz4 extension and the other two affect
archives with .tar.lz4 extension (but one of these is symmetric to the issue
that .tlz4 archives had).
(1) When trying to extract .tlz4 archives the command created by
tar#Extract looked like this:
tar -I lz4pxf foo.tlz4 foo
This isn't right. It should be something like this:
tar -I lz4 -pxf foo.tlz4 foo
This was happening because tar.plugin is just substituting on the
first - in "tar -pxf". This works fine if we just add a simple flag for
extraction (eg, z for .tgz), but for lz4 we need to add "-I lz4".
I don't believe that there is an obvious good way to fix this without
reworking the way the command is generated. Probably we should collect
the command and flags separately and the flags should be stored in a
set. Then put everything together into a string just before issuing it
as an extraction command. Unfortunately, this might break things for users
because they have access to tar_extractcmd.
This patch just makes the substitution a little bit more clever so that it
does the right thing when substituting on a string like "tar -pxf".
(2) .tar.lz4 extractions had the same issue, which my patch fixes in
the same way.
(3) .tar.lz4 extractions had another issue. There was a space missing
in the command generated by tar#Extract. This meant that commands
looked like this (notice the lack of space between the archive and output
file names):
tar -I lz4pxf foo.tar.lz4foo
This patch just puts a space where it should be.
Finally, I should note that ChatGPT 5.4 initially identified this issue
in the code and generated the test cases. I reviewed the test cases,
wrote the patch, and actually ran vim against the tests (both with and
without the patch).

Problem: vim.ui_attach() msg_show callback runs the risk of a recursive
loop_uv_run() when trying to display a message from a shell
command stream.
Solution: Schedule the message callback on the fast_events queue.
Problem: Normal Windows builtin-TUI startup spawns the embedded server as DETACHED_PROCESS, which breaks Ctrl-C delivery to :terminal jobs.
Solution: Restores the default behavior once the embedded server has a
console so terminal jobs inherit it.
Problem: :packadd may lead to heap-buffer-overflow when all entries in
'runtimepath' have the same length (after 9.2.0291).
Solution: Check for comma after current entry properly (zeertzjq).

Problem: too many strlen() calls
Solution: refactor concat_fname() and remove calls to strlen()
(John Marriott)
Function `concat_fnames()` can make up to 5 calls to `STRLEN()` (either
directly or indirectly via `STRCAT()`). In many cases the lengths of
arguments `fname1` and/or `fname2` are either known or can simply be
calculated.
This Commit refactors this function to accept the lengths of arguments
`fname1` and `fname2` as arguments. It also adds new argument `ret` to
return the resulting string as a `string_T`.
Additionally:
- function `add_pack_dir_to_rtp()` in `scriptfile.c`:
Use a `string_T` to store local variables `new_rtp` and `afterdir`.
Replace calls to `STRCAT()` with calls to `STRCPY()`.
Change type of variable `keep` to `size_t` for consistency with
other lengths.
- function `qf_get_fnum()` in `quickfix.c`:
Use a `string_T` to store local variables `ptr` and `bufname`
- function `qf_push_dir()` in `quickfix.c`:
Use a `string_T` to store local variable `dirname`.
Replace call to `vim_strsave()` with `vim_strnsave()`.
- function `qf_guess_filepath()` in `quickfix.c`:
Use a `string_T` to store local variable `fullname`.
- function `make_percent_swname()` in `memline.c`:
Rename some variables to better reflect their use.
Use a `string_T` to store local variables `d` and `fixed_name`.
Slightly refactor to remove need to create an extra string.
- function `get_file_in_dir()` in `memline.c`:
Use a `string_T` to store local variables `tail` and `retval`.
Move some variables closer to where they are used.
- function `cs_resolve_file()` in `if_cscope.c`:
Use a `string_T` to store local variable `csdir`.
Remove one call to `STRLEN()`.
- function `add_pathsep()` in `filepath.c`:
Refactor and remove 1 call to `STRLEN()`
- function `set_init_xdg_rtp()` in `option.c`:
Use a `string_T` to store local variable `vimrc_xdg`.

Problem: Commands that rely on Git may need its version to perform more
targeted actions (like decide which arguments are safe to use).
For performance, computing this version is delayed up until it is
needed (like to not compute on regular startup), but not done before
every Git operation (as it is too much and can be done better).
This requires storing the Git version in a variable which is currently
initiated via `vim.version.parse()` call (most probably because it was
easier to handle Lua types this way).
However, the problem is that this results in sourcing `vim.version`
and computing `vim.version.parse` on every startup even if no Git
operation would be done.
Solution: Don't call `vim.version.parse()` during `require('vim.pack')`
and ensure its more precise lazy computation.
