Problem: Attach-time terminal probes cannot distinguish responses from
different attached UIs.
Solution: Identify the UI by RPC channel id in `TermResponse` and make
`vim.tty.request()` filter responses by channel.
Problem: Clearing the screen doesn't clear the "last" virtual text.
Dupe counter virtual text is not increased beyond 1.
Solution: Clear "last" virtual text when clearing the screen.
Restore assignment lost in a previous commit.
Problem: Terminal background and truecolor detection runs only at startup,
gated on a UI being attached. A headless server has no UI then, so
`'background'` and `'termguicolors'` are never detected and remote
UIs ignore the terminal's theme.
Solution: Also (re)detect on UIEnter. The most recently attached terminal
wins; an explicit user value is preserved.
Problem: Writing a message with a large number of newlines
(:echo "foo\n"->repeat(1000000)) takes longer than it has to
(since c973c7ae).
Solution: Accumulate newlines in a single API call when possible.
Problem:
This test is flaky since fff9897ce3 :
FAILED ...Xtest_xdg_terminal/test/functional/terminal/tui_spec.lua @ 4359:
TUI bg color does not trigger OptionSet from automatic background processing
Expected values to be equal.
Expected:
{ true, 0 }
Actual:
{ true, 1 }
stack traceback:
...Xtest_xdg_terminal/test/functional/terminal/tui_spec.lua:4380:

`apply_optionset_autocmd_now` does not emit `OptionSet` during startup:
void apply_optionset_autocmd_now(...) {
// Don't do this while starting up, failure or recursively.
if (starting || errmsg != NULL || *get_vim_var_str(VV_OPTION_TYPE) != NUL) {
return;
}

}
but if OSC 11 response arrives AFTER VimEnter, then
`nvim_set_option_value('background',…)` call triggers `OptionSet`.
Solution:
Use `:noautocmd` when setting 'background'.
Per fff9897ce3, OSC11 is not intended to trigger OptionSet.

Problem: Processing of a very long message may take a long time; there
is no visual feedback of work being done, and no way to abort
processing.
Calculating text height for spill indicator inhibits
performance for very long message.
Solution: Whenever writing part of a message is taking longer than 100ms,
show the first part of the message, while checking for CTRL-C.
Calculate ('wrap'-ed) text height accurately until 'lines',
use line count beyond that.
Problem:
`nvim_create_autocmd` is too verbose and its `callback` requires extra
"nesting".
Solution:
Introduce `nvim_on`. Start using it internally. Then we can get a feel
for how it should look before making it public.
Problem:
During startup, we manually trigger a useless and misleading `OptionSet`
event, which doesn't set `v:option_*` values (this is a limitation of
`nvim_exec_autocmds`).
ad4bc2d90c/runtime/lua/vim/_core/defaults.lua (L939).
Solution:
The `nvim_exec_autocmds('OptionSet',…)` call does not serve any purpose
since 5cbb9d613b, so just drop it.
Define `:packupdate` and `:packdel` as separate commands instead of a
unified `:pack {subcommand}` because the semantics between the two
commands vary differently enough that it doesn't make sense to combine
them. Additionally, `:pack! update/del` looks bad.
Problem:
- Configuring the height of one of the message targets to 1 is
recognized as 100% of 'lines'.
- Cmdline is expanded for message exceeding 'cmdheight' even if the
configured height is smaller than or equal to 'cmdheight'.
Solution:
- Recognize a height of 1 as absolute; a decimal number smaller than 1
is taken as a fraction of 'lines' (replace 1 with 0.999 for the old
behavior).
- Don't expand the cmdline if the configured height doesn't allow it.
Problem: - "bufwrite" message identifier is encoded in the message ID
of a "progress" kind message (since ff68fd6b); UI2 does not
allow routing by message ID.
- No documented way to set a default message target for all
but a few kinds (without copying all of |ui-messages| kinds
to cfg.msg.targets).
- A user adding a message route for the documented empty ""
kind can result in unexpected behavior.
- Showing duplicate message (x) indicator in msg and cmd
targets simultaneously is unsupported.
- Manually triggering CursorMoved autocommand to add matchparen
highlighting in the cmdline.
Solution: - Match cfg.msg.targets keys as Lua pattern to a message ID.
- Recognize "default" as key in cfg.msg.targets, drop the
undocumented cfg.msg.target field.
- Don't try to get configured target for "" message kind/trigger.
- Maintain msg indicator virtual text for the cmd and msg target.
- Add matchparen highlighting by directly calling the Lua module
(possible since b813c7e0).
Problem:
Regression from c822a2657c: `vim.wait(0)` does not call `loop_poll`,
so `vim.wait(1)` is needed to "yield" from Lua.
Solution:
- Ensure that `vim._core.loop_poll()` is always called, even when `time=0`.
- Document how to interrupt Lua code (ctrl-c).

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:
When showing the :connect menu, it is useful to know which servers
are most-recently active. But we don't have a good way to detect that.
Solution:
- Introduce `v:useractive`.
- Include this timestamp in `serverlist({info=true})`.

Problem: Entering the pager fails if <ESC> is remapped to :fclose by user.
Solution: Avoid executing mappings with nvim_feedkeys() that closes expanded cmdline.
Problem:
UI tools and orchestration engines need more context than just raw
socket addresses from serverlist(). Without knowing if a server belongs
to the current instance or knowing its PID, UIs cannot display
meaningful options to users.
Solution:
- Added the `info=v:true` option to `serverlist()`.
- When `info` is requested, it implies `peer=true` and returns a list of
dictionaries (defined as `vim.ServerInfo`) with `addr`, `pid` and
`own`.
- Uses an RPC request to `getpid()` across the socket to fetch the
peer's actual process ID.

Problem:
When using `vim.list.unique` or `vim.list.bisect`, if the `key` function is
complex, it can degrade performance, because it is invoked on every comparison
Solution:
The `key` interface convention is designed specifically to address this issue;
performance can be improved by memoizing its results.
Also added the shorthand use of the field name string as the key.
Problem:
The fallback that tokenizes `eap->arg` by unescaped whitespace (when the
parser doesn't pre-split via `EX_EXPAND` etc.) lives in `nlua_do_ucmd`,
so only user-command callbacks got `eap.fargs`. Builtin commands routed
through `nlua_call_excmd` have to re-parse the args themselves
(e.g. `M.ex_lsp`).
Solution:
- Move the tokenization into `nlua_push_eap` so every Lua handler sees
`eap.fargs`. Keep only the `EX_NOSPC` override in `nlua_do_ucmd` (the
`nargs=1`/`?` case which is genuinely user-command-specific).
- Drop the re-parse in `M.ex_lsp`.
Problem:
The argument to `:help` is normalized to fit the general tag format.
I.e. i^U-default, iCTRL-U-default and i_CTRL_U-default should all point
to the i_CTRL_U-default tag. Our normalization adds an underscore around
the CTRL keycode, e.g. iCTRL-GCTRL-J becomes i_CTRL-G_CTRL-J. That's not
necessary if the following part starts with a dash, like the case of
iCTRL-U-default.
Solution:
Do not insert an underscore if the following character is a dash/minus
(-).
Problem:
After 55ceb31, z= and tselect don't work if `vim.ui.select` is an async
provider (especially terminal buffers).
Solution:
Drop the `vim.wait()` approach, use an async approach.
fix#39506
Problem:
followup to 55ceb314ca#39478
`:oldfiles` and swapfile `:recover` do not delegate to `vim.ui.select`.
Solution:
- Delegate to `vim.ui.select`.
- Fix a long-standing `recover_names` bug where `concat_fnames(dir_name,
files[i], true)` produced malformed `<dir>//<dir>/<file>` paths (also
fixes `swapfilelist()`).
Problem:
- Various `TermRequest` handlers which all do similar things.
- `tty.query` is specific to `XTGETTCAP DCS`, can't be reused for other kinds of terminal queries.
Solution:
Provide `tty.request()`.
Problem:
Error when querying document symbols using python-lsp-server:
lsp/util.lua:1955: attempt to concatenate field 'containerName' (a userdata value)
Solution:
Check for `vim.NIL`.
Problem:
`:tselect` and `z=` (spell suggest) have their own bespoke select menus.
Solution:
- Delegate to `vim.ui.select` instead.
- Bonus:
- `:tselect` gains mouse support. `print_tag_list` didn't suport mouseclick.
This causes some minor regressions, which are not blockers:
- `z=` no longer draws the list right-left if 'rightleft' is set.
- TODO: can/should `vim.ui.select` / `vim.fn.inputlist()` handle that?
- `:tselect`
- No "column" headings (`# pri kind tag file`).
- No highlighting: (HLF_T: tag name, HLF_D: file, HLF_CM: extra fields).
- TODO: can `vim.ui.select()` support highlighted chunks (`[[text, hl_id], ...]`) ?

fix https://github.com/neovim/neovim/issues/31987
Problem:
`v:starttime`, `:uptime` use a monotonic high-resolution timer. This
only works as long as the timer keeps running (if the computer is
suspended the timer is paused). This is somewhat unintuitive, and
doesn't match the behavior of the `uptime` shell command.
Solution:
Implement `os_realtime` to get the real time since the
epoch in nanoseconds.
Move vim.wait into runtime/lua/vim/_core/editor.lua and replace
the C entrypoint with narrow vim._core helpers for polling, UI
flushing, and interrupt checks.
Keep the existing interval semantics by retaining the dummy timer that
wakes the loop while it is otherwise idle.
Update the docs to describe the success return values correctly, and
adjust the test expectation for the new vim.validate() callback error.

Problem: There are many Git forges each with a different way of
constructing permanent links to like commits and tags.
Solution: Add a private utility function that computes these special
links on the best effort basis.
Problem:
When running nvim on a remote machine over SSH, if there is high ping,
then bg detection may not complete in time. This results in a warning
every time nvim is started. #38648
Solution:
Restore 'ttyfast' option and allow it to control whether or not bg
detection is performed. Because this is during startup and before any
user config or commands, we use the environment variable
`NVIM_NOTTYFAST` to allow disabling `ttyfast` during initialization.
