Problem:
Since 2448816956, the --startuptime report shows
two blocks of data. The TUI process and its embedded nvim process write to the
file concurrently, which may interleave the two startup sequences into the same
timeline.
Solution:
Report each process as a separate section in the same file.
1. Each process buffers the full report.
2. After startup is finished, the buffer is flushed (appended) to the file.
Fix#23036

Problem:
rbuffer_consumed assertion fails if Unpacker fails to parse msgpack,
because it doesn't consume bytes on errors
Solution:
Call rbuffer_consumed_compact only if Unpacker isn't closed
The motivation for this update is Issue #15365, where background=light
is not properly set for Nvim running from an Nvim :terminal. This can be
encountered when e.g., opening a terminal to make git commits, which
opens EDITOR=nvim in the nested terminal.
Under the implementation of this commit, the OSC response always
indicates a black or white foreground/background. While this may not
reflect the actual foreground/background color, it permits 'background'
to be retained for a nested Nvim instance running in the terminal
emulator. The behaviour matches Vim.
Problem:
Not all Lua code is checked by stylua. Automating code-style is an
important mechanism for reducing time spent on accidental
(non-essential) complexity.
Solution:
- Enable stylua for entire `test/` directory.
- Exclude these high-churn files until this issue is resolved: https://github.com/JohnnyMorganz/StyLua/issues/829
```

test/functional/ui/float_spec.lua | 5826 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++-------------------------
test/functional/ui/multigrid_spec.lua | 1349 ++++++++++++++------
```
- Make surgical changes to these files (or add `stylua: ignore` in some
small scopes) to improve the result:
```
test/functional/vimscript/msgpack_functions_spec.lua | 1414 +++++++++++++++------
test/functional/api/buffer_spec.lua | 1389 +++++++++++----------
test/functional/api/vim_spec.lua | 2740 +++++++++++++++++++++++-----------------
```
- These "high churn" files are NOT excluded because the changes are
largely an improvement:

- TODO: how to check "all directories"? With `GLOB_DIRS *` and `/.deps/` (or
`.deps/`) in `.styluaignore`, Lua code in `.deps/` is still checked...
Problem: Updating default color scheme produced some feedback.
Solution: Address the feedback.
Outline of the changes:
- Colors `Grey1` and `Grey2` are made a little bit more extreme (dark -
darker, light - lighter) to increase overall contrast.
- `gui` colors are treated as base with `cterm` colors falling back to
using 0-15 colors which come from terminal emulator.
- Update highlight group definition to not include attribute definition
if it is intended to staty uncolored.
- Tweak some specific highlight groups.
- Add a list of Neovim specific highlight groups which are now defined
differently in a breaking way.
- Minor tweaks in several other places related to default color scheme.
uv_close asserts that a handle is not already closing. We can guard
against this assertion failure by manually checking the handle's closing
status ourselves.
This is the command invoked repeatedly to make the changes:
:%s/^\(.*\)|\%(\*\(\d\+\)\)\?$\n\1|\%(\*\(\d\+\)\)\?$/\=submatch(1)..'|*'..(max([str2nr(submatch(2)),1])+max([str2nr(submatch(3)),1]))/g
Set 'notermguicolors' in tests which spawn a child Nvim process to force
existing tests to use 16 colors. Also refactor the child process
invocation to make things a little bit less messy.

Relax the assertion.
Problem:
The test for 'nofsync' swapfile preservation on a deadly signal, does

Check that swapfile contents are present after getting SIGTERM.
TODO: this doesn't really verify that 'fsync' was called; it still
passes with this patch:

Solution:
Relax the assertion to `fsync >= 2` instead of exactly 2.
(Note this is not a behavior change: the next assertion has always
checked `fsync == 4`, it's just that the intermediate 3rd fsync was
never explicitly asserted.)
Problem: Default color scheme is suboptimal.
Solution: Start using new color scheme. Introduce new `vim` color scheme
for opt-in backward compatibility.
------
Main design ideas
- Be "Neovim branded".
- Be minimal for 256 colors with a bit more shades for true colors.
- Be accessible through high enough contrast ratios.
- Be suitable for dark and light backgrounds via exchange of dark and
light palettes.
------
Palettes
- Have dark and light variants. Implemented through exporeted
`NvimDark*` and `NvimLight*` hex colors.
- Palettes have 4 shades of grey for UI elements and 6 colors (red,
yellow, green, cyan, blue, magenta).
- Actual values are computed procedurally in Oklch color space based on
a handful of hyperparameters.
- Each color has a 256 colors variant with perceptually closest color.
------
Highlight groups
Use:
- Grey shades for general UI according to their design.
- Bold text for keywords (`Statement` highlight group). This is an
important choice to increase accessibility for people with color
deficiencies, as it doesn't rely on actual color.
- Green for strings, `DiffAdd` (as background), `DiagnosticOk`, and some
minor text UI elements.
- Cyan as main syntax color, i.e. for function usage (`Function`
highlight group), `DiffText`, `DiagnosticInfo`, and some minor text UI
elements.
- Red to generally mean high user attention, i.e. errors; in particular
for `ErrorMsg`, `DiffDelete`, `DiagnosticError`.
- Yellow very sparingly only with true colors to mean mild user
attention, i.e. warnings. That is, `DiagnosticWarn` and `WarningMsg`.
- Blue very sparingly only with true colors as `DiagnosticHint` and some
additional important syntax group (like `Identifier`).
- Magenta very carefully (if at all).
------
Notes
- To make tests work without relatively larege updates, each one is
prepended with an equivalent of the call `:colorscheme vim`.
Plus some tests which spawn new Neovim instances also now use 'vim'
color scheme.
In some cases tests are updated to fit new default color scheme.
Problem:
'nofsync' may lose data if the system has a hard shutdown. #9888
Solution:
Change default to 'fsync'. This may be revisited in the future when
'nofsync' can be made safer.
Using fnameescape() for the path argument of findfile() and finddir() is
wrong, as fnameescape() is intended to be used for parts of Ex commands,
not function arguments.
Problem:
On Windows, "gf" fails on a filepath that has a line:column suffix.
Example:
E447: Can't find file "src/app/core/services/identity/identity.service.ts:64:23"
Solution:
- Remove ":" from 'isfname' on Windows. Colon is not a valid filename
character (except for the drive-letter).
- Handle drive letters specially in file_name_in_line().
Fixes#25160
msg_puts_display was more complex than necessary in nvim, as in
nvim, it no longer talks directly with a terminal.
In particular we don't need to scroll the grid before emiting the last
char. The TUI already takes care of things like that, for terminals
where it matters.
Problem:
NVIM_APPNAME does not allow path separators in the name, so relative
paths can't be used:
NVIM_APPNAME="neovim-configs/first-config" nvim
NVIM_APPNAME="neovim-configs/second-config" nvim
Solution:
Let NVIM_APPNAME be a relative path. Absolute paths are not supported.
fix#23056fix#24966
Problem:
helpers.tmpname() may create a local file, depending on circumstances.
Solution:
Only use helpers.tmpname() for its parent directory (the "temp root").
Use fs_mkdtemp() to actually get a unique name.
