Problem: Crash when initializing for --startuptime errors.
Solution: Report the error to stderr, as neither logging nor messages
have been initialized yet.
Problem: Ext_messages chunks only contain the highlight attr id, which
is not very useful for vim.ui_attach() consumers.
Solotion: Add highlight group id to message chunks, which can easily be
used to highlight text in the TUI through nvim_buf_set_extmark():
hl_group = synIDattr(id, "name").
Problem: Highlight group id is not propagated to the end of the message call
stack, where ext_messages are emitted.
Solution: Refactor message functions to pass along highlight group id
instead of attr id.
Problem: Inccommand preview callback may flush inaccurate cmdline cursor position.
Solution: Ensure cursor is where it belongs when doing command preview.
Problem: Can receive dozens of <MouseMove> events for same cell position. #30965
Solution: Leverage check_multiclick() to detect if cell position is unchanged.
Problem:
When tmpdir is local. The returned values from tmpname may already
exist. This can cause problems for tests which pass `create=false` as
they may require the file to not exist yet.
Solution:
When creating tmp names, always remove it to ensure it doesn't exist,
and optionally open it if `create~=false`
Additionally refactor the tmpname code and flattrn some functions into
constants.
Also while debugging this issue. It was discovered that `exec_lua()`
doesn't report error messages properly. This has been fixed.

Problem: tests: still preferring python2 over python3
Solution: prefer Python 3 when picking a Python program in Vim tests,
by checking for the more specific python version first and
only when python3 not found, check for the python binary
(Yee Cheng Chin)
Most OSes have Python 3 mapped to `python3` instead of `python`. Vim
tests should prioritize using that instead of Python 2 in case that is
still installed on the host system.

Problem:
There are three different ways of marking an option as hidden, `enable_if
= false`, `hidden = true` and `immutable = true`. These also have different
behaviors. Options hidden with `enable_if = false` can't have their value
fetched using Vim script or the API, but options hidden with `hidden = true` or
`immutable = true` can. On the other hand, options with `hidden = true` do not
error when trying to set their value, but options with `immutable = true` do.
Solution:
Remove `enable_if = false`, remove the `hidden` property for options, and use
`immutable = true` to mark an option as hidden instead. Also make hidden option
variable pointers always point to the default value, which allows fetching the
value of every hidden option using Vim script and the API. This does also mean
that trying to set a hidden option will now give an error instead of just being
ignored.
while the implementation is not tied to screen chars, it is a reasonable
expectation to support the same size. If nvim is able to display a
multibyte character, it will accept the same character as input,
including in normal mode commands like r{char}

feat(diagnostics)!: sort underline with severity_sort
BREAKING CHANGE: underline will be applied with a higher value than `vim.hl.priorities.diagnostics`
* deprecate old signatures
* move to new str_byteindex/str_utfindex signature
* use single-underscore name (double-underscore is reserved for Lua itself)
Problem: We use `void *` for option default values, which is confusing and can cause problems with type-correctness. It also doesn't accomodate for multitype options. On top of that, it also leads to default boolean option values not behaving correctly on big endian systems.
Solution: Use `OptVal` for option default values.
BREAKING CHANGE:
- `:set {option}<` removes the local value for all global-local options instead of just string global-local options.
- `:setlocal {option}<` copies the global value to the local value for number and boolean global-local options instead of removing the local value.

PROBLEM:
There are several limitations to vim.str_byteindex, vim.str_utfindex:
1. They throw given out-of-range indexes. An invalid (often user/lsp-provided)
index doesn't feel exceptional and should be handled by the caller.
`:help dev-error-patterns` suggests that `retval, errmsg` is the preferred
way to handle this kind of failure.
2. They cannot accept an encoding. So LSP needs wrapper functions. #25272
3. The current signatures are not extensible.
* Calling: The function currently uses a fairly opaque boolean value to
indicate to identify the encoding.
* Returns: The fact it can throw requires wrapping in pcall.
4. The current name doesn't follow suggestions in `:h dev-naming` and I think
`get` would be suitable.
SOLUTION:
- Because these are performance-sensitive, don't introduce `opts`.
- Introduce an "overload" that accepts `encoding:string` and
`strict_indexing:bool` params.
```lua
local col = vim.str_utfindex(line, encoding, [index, [no_out_of_range]])
```
Support the old versions by dispatching on the type of argument 2, and
deprecate that form.
```lua
vim.str_utfindex(line) -- (utf-32 length, utf-16 length), deprecated
vim.str_utfindex(line, index) -- (utf-32 index, utf-16 index), deprecated
vim.str_utfindex(line, 'utf-16') -- utf-16 length
vim.str_utfindex(line, 'utf-16', index) -- utf-16 index

**Problem:** Tree-sitter 0.24.0 introduced a new symbol type to denote
supertype nodes (`TSSymbolTypeSupertype`). Now, `language.inspect()`
(and the query `omnifunc`) return supertype symbols, but with double
quotes around them.
**Solution:** Mark a symbol as "named" based on it *not* being an
anonymous node, rather than checking that it is a regular node (which a
supertype also is not).
**Problems:**
- `vim.treesitter.language.inspect()` returns duplicate
symbol names, sometimes up to 6 of one kind in the case of `markdown`
- The list-like `symbols` table can have holes and is thus not even a
valid msgpack table anyway, mentioned in a test
**Solution:** Return symbols as a map, rather than a list, where field
names are the names of the symbol. The boolean value associated with the
field encodes whether or not the symbol is named.
Note that anonymous nodes are surrounded with double quotes (`"`) to
prevent potential collisions with named counterparts that have the same
identifier.
This commit also marks `child_containing_descendant()` as deprecated
(per upstream's documentation), and uses `child_with_descendant()` in
its place. Minimum required tree-sitter version will now be `0.24`.

Problem: Lua accessors for
- global, local, and special variables (`vim.{g,t,w,b,v}.*`), and
- options (`vim.{o,bo,wo,opt,opt_local,opt_global}.*`),
do not have command-line completion, unlike their vimscript counterparts
(e.g., `g:`, `b:`, `:set`, `:setlocal`, `:call <fn>`, etc.).
Completion for vimscript functions (`vim.fn.*`) is incomplete and does
not list all the available functions.
Solution: Implement completion for vimscript function, variable and
option accessors in `vim._expand_pat` through:
- `getcompletion()` for variable and vimscript function accessors, and
- `nvim_get_all_options_info()` for option accessors.
Note/Remark:
- Short names for options are yet to be implemented.
- Completions for accessors with handles (e.g. `vim.b[0]`, `vim.wo[0]`)
are also yet to be implemented, and are left as future work, which
involves some refactoring of options.
- For performance reasons, we may want to introduce caching for
completing options, but this is not considered at this time since the
number of the available options is not very big (only ~350) and Lua
completion for option accessors appears to be pretty fast.
- Can we have a more "general" framework for customizing completions?
In the future, we may want to improve the implementation by moving the
core logic for generating completion candidates to each accessor (or
its metatable) or through some central interface, rather than writing
all the accessor-specific completion implementations in a single
function: `vim._expand_pat`.
An implication of this current approach is that `NVIM_API_LEVEL` should be
bumped when a new Lua function is added.
TODO(future): add a lint check which requires `@since` on all new functions.
ref #25416
Some composite/compound types even as basic as `(string|number)[]` are

Problem: quickfix list does not handle hardlinks well
Solution: store original file name with quickfix entry
(Austin Chang)
Quickfix list shows entries with duplicate name if the file is opened
with the path of hard links.
The major cause is that qflist assumed that the filename passed into
`qf_add_entry` matches the filename opened with the buffer.
This patch handles this case by introduce a `qf_fname` into `qfline_S`
structure. It stores the filename from `qf_add_entry` for each quickfix
line.

Ensure the screen is fully updated before blocking for input. This did
not always happen before, for example when setting `cursorline
scrolloff=9999`, which lead to jerky movement when using some GUI
applications.
Because of the duality of redraw_later, this can't be done in
command-line or when waiting for "Press ENTER". In many of those cases
the redraw is expected AFTER the key press, while normally it should
update the screen immediately. So, those special cases are excluded.

FUTURE:
This is a cheap workaround until we have #25718 which will enable:
- fully driven by `vimdoc/highlights.scm` instead of using highlight
tricks (`guibg=bg guifg=bg guisp=fg`)
- better support of "cterm" ('notermguicolors')
