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:
parser_gc() calls ts_parser_delete() but leaves the userdata pointer
pointing to freed memory. If the GC finalizer runs at an unexpected time
(e.g. inside nvim_buf_get_lines #39411), a stale pointer could cause a crash.
Solution:
- NULL out `*ud` after ts_parser_delete() in parser_gc()
- Update parser_check() to handle NULL with a clear error message,
guarding all parser methods against UAF

Problem:
For a given position, it is not easy to compare which of several other positions is closest to it.
Solution:
Add support for converting `vim.Pos` to a buffer byte offset.
This allows for sorting, e.g:
```lua
table.sort(positions, function(pos1, pos2)
return pos1:to_offset() < pos2:to_offset()
end
```
Or a binary search, e.g:
```lua
vim.list.bisect(positions, pos, { key = function(pos) return pos:to_offset() end })
```
Problem: Internal progress messages use the "nvim" source (since
ff68fd6b), plugins shouldn't be allowed to set the progress
message source to "nvim". The message ID used for internal
progress messages is not identifiable as such.
Solution: Disallow setting opts->source to "nvim" with nvim_echo().
Refactor msg_progress() and callees to bypass nvim_echo().
Prepend message id for internal progress messages with "nvim.".
Improve the vim.iter annotations with richer generics that track element and
tuple types through iterator pipelines, including multi-value stages and
list-specific methods.
Extend the LuaCATS parser and vimdoc generator so those richer generic classes
and overloads round-trip into the generated help. These annotations are only
supported by EmmyLua, so LuaLS still uses a broader fallback in _meta.lua.

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.

`definition` is now empty when cmd is function type.
Problem: When find_start_brace() scans backwards for the enclosing
block, '{' and '}' inside // and /* */ comments are counted,
producing wrong indent for code following such comments
(rendcrx).
Solution: Implement FM_SKIPCOMM in findmatchlimit() to track block-
comment state and skip matches inside comments. Pass
FM_SKIPCOMM from cindent's call sites
(find_start_brace, find_match_char, cin_iswhileofdo,
get_c_indent).

Problem: off-by-one bug in s:NetrwUnMarkFile()
Solution: Correctly loop through all buffers to unlet all variables
(J. Paulo Seibt)
When the function loops through buffers to clear s:netrwmarkfilelist_#
and s:netrwmarkfilemtch_#, it skips the last one at bufnr('$'), messing
up mark highlights and causing other functions that operate on those
arrays (like delete or rename) to target stale marked files.
The bufnr() help page says that bufnr("$") returns the highest buffer
number of existing buffers, so while ibuf < bufnr("$") does not clear
the last buffer-local arrays.
To reproduce:
Just opening a fresh Vim and running :Ex opens a netrw buffer at the
highest number. Then, typing mu after marking some files triggers the
mark highlight bug, and finally typing D would act like calling the
delete function against the previous marked files, as the buffer-local
arrays where not touched by s:NetrwUnMarkFile.

Problem: When closing gvim with an unsaved unnamed buffer, choosing
"Yes" in the "Save changes?" dialog and then "Cancel" in the
file selection dialog either silently writes the buffer to a
file named "Untitled" (overwriting any existing file with
that name) or discards the buffer altogether
(vibs29, after v9.1.0265).
Solution: In dialog_changed(), if browse_save_fname() leaves the buffer
without a file name, treat it as a cancel and return without
saving. Also stop clearing the modified flag in the restore
path on write failure, so the unsaved changes are kept and
the caller (e.g. gui_shell_closed()) can also cancel the
close. Pre-fill the file dialog with "Untitled" to match
the preceding "Save changes to ..." prompt. Add a test for
the write-failure path (Hirohito Higashi).

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:
Nested workspace capabilities like workspace.fileOperations.didCreate and
workspace.textDocumentContent are not handled consistently for dynamic and
static registration provider lookup.
Solution:
Generate explicit registration-provider mappings from the LSP metadata and use
them when registering and querying capabilities. Add coverage for dynamic and
static nested workspace registrations.
Problem:
With 'incsearch' enabled, the window can scroll while typing a
search pattern, but WinScrolled is not triggered until the next user
action in Normal mode. The event is effectively skipped for every
scroll that happens while the search prompt is still open.
Solution:
Call may_trigger_win_scrolled_resized() after update_screen()
in may_do_incsearch_highlighting() and finish_incsearch_highlighting().
Problem:
`EBUSY` during cleanup:
Windows CI can intermittently fail `pack_spec.lua` with `EBUSY` while removing
`site/pack/core/opt/plugindirs`.
This can happen because:
- the test Nvim session may still be alive when `after_each()` removes the pack
directory
- Windows does not allow removing a directory while another process still has an
open handle below it
- startup-time `vim.pack.add()` performs a real `git clone`, so process and file
handle release timing can vary on slower runners
Startup timeout:
The startup tests can also fail before cleanup because they wait for `_G.done`
with a fixed timeout. That timeout includes the time needed for startup to run
`vim.pack.add()` and finish the local clone.
Solution:
Close before cleanup:
Capture the pack, lockfile, and log paths while the test Nvim session is still
available, then call `n.check_close()` before removing the pack directory.
Extend Windows startup wait:
Increase the `_G.done` retry budget only on Windows so startup-time
`vim.pack.add()` has more time to finish on slower CI runners.
Problem:
The `nvim_get_chan_info()` terminal channel test used `shell-test INTERACT` to verify that `jobstop()` reports an unhandled `SIGHUP` as exit code `129`.
`INTERACT` reads from stdin with `fgets()`, so closing the PTY could race with `SIGHUP` delivery. If `fgets()` observed EOF first, `shell-test` exited normally with code `0`, causing intermittent failures on slower sanitizer builds.
Solution:
Add a `shell-test HOLD` mode that prints a readiness prompt and then waits without reading stdin. Use it for the `SIGHUP` assertion so PTY EOF cannot make the helper exit normally before the signal path is observed.
Problem: Test_termdebug_tbreak(), Test_termdebug_basic(), and
Test_termdebug_toggle_break() use synchronous assert_equal()
to check breakpoint signs immediately after sending commands
to gdb. On slow CI (ASAN, ARM64, macOS) gdb may not have
processed the response yet, causing the sign to be missing.
Solution: Wrap the three assertions in WaitForAssert() to poll until
the signs are placed, matching the pattern already used by
the other assertions in the same tests (Jesse Rosenstock).

Nvim already behaves correctly. Add a screen test as there are none.
Problem:
`gx` relies on `exepath` to get the fullpath of `cmd.exe`,
and that path must use `\`; otherwise, luv's spawn will fail.
Solution:
Revert `slash_adjust` in `exepath`, so that it still respects 'shellslash'
Problem:
This test would sometimes fail to match lines starting with `.` (indicating throttling) due to a race condition, likely because throttling completed before the test could properly assert.
Solution:
I 6x'd the amount of test data we were pushing into `nvim` in an attempt to trigger throttling consistently.
I don't _love_ this solution as it is still non-deterministic and might not hold up over time.
A good solution would be: create a deterministic way to pause neovim in a functional test, assert on the temporarily throttle state, then unpause neovim. However, it's likely this is not possible today and will take too much effort.
Before test time (30000 lines): ~0.40sec/run
After test time (150000 lines): ~1.7sec/run
This increases test runtime, but if it removes flakes I think it's worth it.
Problem: customlist completion cannot supply pum metadata

Problem: When an error line in a file passed to :cfile / :cgetfile is
longer than IOSIZE, qf_parse_file_pfx() copies the tail
into the fixed-size IObuff with STRMOVE(), overflowing the heap buffer.
The same code path can also loop indefinitely because
qf_parse_file_pfx() always returns QF_MULTISCAN when a
tail is present, and qf_init_ext() unconditionally goes
to "restofline" without bounding the tail length (Nabih).
Solution: Remove the STRMOVE() into IObuff. In the QF_MULTISCAN
branch, alias linebuf into the tail directly and update
linelen, requiring strict progress (new length less than
the previous length) before retrying; otherwise ignore
the line.

Problem:
`get_node_text()` returned inconsistent results between buffer and
string sources when a node's range ends at `end_col == 0` (i.e. the node
ends with a newline). The buffer path dropped the trailing newline; the
string path included it correctly.
Solution:
Append `'\n'` in `buf_range_get_text()` when `end_col == 0` and
`start_row ~= end_row`. The `start_row ~= end_row` guard excludes
zero-width nodes at column 0, which should return `""`.
Remove the workaround in the `#trim!` directive that manually
compensated for the missing newline.
Strip whitespace in `resolve_lang()` so injection language nodes ending
at `end_col == 0` (e.g. `">lua\n"`) still resolve correctly.
Problem: tests: Test_shortmess_F3() is flaky on MS-Windows
Solution: Increase the sleep to 3s (Yasuhiro Matsumoto)
On MS-Windows time_differs() treats mtime as unchanged unless st_mtime
differs by more than 1 second, so a 2-second sleep can fall short when
the two writes straddle a second boundary. Bump the non-nanotime sleep

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: With $d='[dir]', `:e $d/file.txt` opens the wrong file,
`:e $d/<Tab>` fails to complete, and `glob('$d/*')` returns
nothing. Wildcard characters inside expanded environment
variables get picked up by globbing again.
Solution: Turn the 4th parameter of expand_env_esc() from a bool into a
string of characters to escape in each expanded value. Callers
that pass the result to wildcard expansion should include
PATH_ESC_WILDCARDS in addition to " \t" (glepnir).

Problem:
LSP clients previously did not handle dynamic registration for off-spec methods

custom dynamic registrations.

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.

Do not insert an underscore if the following character is a dash/minus
