518aa46158 vim-patch:9.2.0090: "leadtab" behavior inconsistent on line with only TABs
Problem:  "leadtab" behavior inconsistent on line with only TABs
          (after 9.2.0088).
Solution: Don't consider those as leading TABs. Also add more tests for
          existing behavior of "lead" and "leadmultispace" (zeertzjq).

3e81072293 vim-patch:9.2.0088: cannot display tabs for indentation
Problem:  cannot display tabs for indentation
Solution: Add the "leadtab" value to the 'listchars' option to
          distinguish between tabs used for indentation and tabs used
          for alignment (HarshK97).

a8361c3afc docs(diagnostics): use the original namespace in "on-jump" example (#38124)
Problem: currently in the example a new diagnostic namespace is created
for showing it manually with a custom config. Because of a separate
namespace, when the original diagnostic source sets diagnostics again,
it will not affect the diagnostic shown in that new namespace and the
user would need to implement the logic for hiding it themselves,
separately as well.

Solution: instead of creating a new namespace, reuse the original
diagnostic's namespace, so once the source sets diagnostics again, it's
removed and hidden automatically without user having to do anything
extra for that.

ab8371a26c fix(tui): server --listen error sometimes not visible (#38027)
Problem:  If Nvim server fails to --listen and prints error before the
          TUI enters alternate screen, the error isn't visible.
Solution: Forward server stderr using client side stderr handler instead
          of having the server inherit client stderr file descriptor.

This does mean that `stderr_isatty` will be `false` in the server, but
that value doesn't matter in embedded mode.

Always pass `stdin_fd` to embedded server to avoid a hang when reading
from stdin when it's a TTY (not sure why one wants to do that, perhaps
by mistake), because if `stdin_fd` isn't passed, the server will try to
use stderr as stdin.

Example test failure on CI:

FAILED   test/functional/terminal/tui_spec.lua @ 41: TUI exit status 1 and error message with server --listen error #34365
test/functional/terminal\tui_spec.lua:55: Failed to match any screen lines.

dea8430d59 test: suppress DSR wait warning when running tests (#38126)
Problem:
The DSR wait warning causes any test that involves Nvim TUI to become
flaky on Windows. Example:

c1e60f36f3 fix(difftool): don't reset quickfix list when closing quickfix window #38088
Closing the quickfix window previously triggered a WinClosed autocmd
that deleted all difftool autocmds and pushed an empty quickfix list,
making the difftool non-functional. Users who close the quickfix window
to gain screen real estate for viewing diffs had no way to continue
navigating entries.

Remove the qf_win tracking and its associated WinClosed autocmd so that
closing the quickfix window no longer tears down the difftool state.
Closing either diff window still performs full cleanup as before.

The BufWinEnter handler no longer passes with_qf to diff_files, so
navigating entries while the quickfix window is closed reuses the
existing diff layout without forcing a layout rebuild.

Fixes #37388

32e0d05d53 feat(ui2): configure targets per message kind #38091
Problem:  Unable to configure message targets based on message kind.
Solution: Add cfg.msg.targets mapping message kinds to "cmd/msg/pager".
          Check the configured target when writing the message.
          cfg.msg = { target = 'cmd', targets = { progress = 'msg', list_cmd = 'pager' } }
          will for example use the 'msg' target for progress messages,
          immediately open the pager for 'list_cmd' and use the cmdline
          for all other message kinds.

b40ca5a01c fix(channel): support :detach, :restart on Windows #37977
fix: allocate hidden console for detached server

Starting the server with UV_PROCESS_DETACHED results in DETACHED_PROCESS, leaving the child without a console. Without a console:

CONIN$ / CONOUT$ cannot resolve, causing channel_from_stdio to fail.

ConPTY cannot attach, breaking :terminal.

This patch allocates a hidden console via AllocConsole() when the server has none, restoring working stdio and enabling ConPTY.

Also updates os_set_cloexec to clear HANDLE_FLAG_INHERIT on the RPC pipe
handles, matching the Unix F_DUPFD_CLOEXEC behavior.

Problem:  memline: a crafted swap files with bogus pe_page_count/pe_bnum
          values could cause a multi-GB allocation via mf_get(), and
          invalid pe_old_lnum/pe_line_count values could cause a SEGV

Solution: Add bounds checks on pe_page_count and pe_bnum against
          mf_blocknr_max before descending into the block tree, and
          validate pe_old_lnum >= 1 and pe_line_count > 0 before calling
          readfile().

a416494e64 vim-patch:9.2.0078: [security]: stack-buffer-overflow in build_stl_str_hl() (#38102)
Problem:  A stack-buffer-overflow occurs when rendering a statusline
          with a multi-byte fill character on a very wide terminal.
          The size check in build_stl_str_hl() uses the cell width
          rather than the byte length, allowing the subsequent fill
          loop to write beyond the 4096-byte MAXPATHL buffer
          (ehdgks0627, un3xploitable).
Solution: Update the size check to account for the byte length of
          the fill character (using MB_CHAR2LEN).

e85fc92a6b vim-patch:9.2.0075: [security]: Buffer underflow with emacs tag file
Problem:  When parsing a malformed Emacs-style tags file, a 1-byte
          heap-buffer-underflow read occurs if the 0x7f delimiter
          appears at the very beginning of a line. This happens
          because the code attempts to scan backward for a tag
          name from the delimiter without checking if space exists.
          (ehdgks0627, un3xploitable)
Solution: Add a check to ensure the delimiter (p_7f) is not at the
          start of the buffer (lbuf) before attempting to isolate
          the tag name.

c4fdd3b072 vim-patch:9148644: runtime(env): add ftplugin for env filetype (#38098)
Patch 9.2.0033 (vim/vim#19260) introduced a dedicated `env` filetype for
.env files, which were previously detected as `sh`. This left env
files without `commentstring`, `comments`, or `formatoptions` since
no ftplugin was added alongside the new filetype.

Add runtime/ftplugin/env.vim to set these options, matching the
behavior that .env files had when they used the `sh` filetype.

453dfbf7d6 vim-patch:9.1.0535: newline escape wrong in ex mode
Problem:  newline escape wrong in ex mode (Konrad Schwarz)
Solution: partly revert patch 7.3.014, remove backslash in front of a
          newline when not in prompt mode in ex line mode
          (Mohamed Akram)

This fixes newline escaping to allow passing multiple commands to
":global", multiple lines to shell commands, and ending lines in append
mode with backslashes. This should fix a POSIX/(traditional) VI
incompatiblity.

This reverts a previous incorrect attempt at patch v7.3.014 to fix
append mode which removed half of trailing backslashes which lead to,
eg. the following two commands being parsed as having a different number
of backslashes:

```
!echo foo\\\
```

```
!echo foo\\ \
```

4a4de73043 fix(help): better align local-additions #38097

Descriptions of plugins often contain taglinks which are generally
concealed. This misaligns them by 2 characters with descriptions that

Solution:
Don't count "bar" characters (`|`) for the description width.

Example:

Actual buffer content:
```
myplugin.txt                  |lsp| is cool
myplugin.txt        this is a nice plugin
```

Rendered as:

dc5d313d66 fix(vim.fs): joinpath() should ignore empty items #38077
Problem:
vim.fs.joinpath treats empty string as a path segment
(it adds a path separator for each empty item):

    print(vim.fs.joinpath('', 'after/lsp', '')) -- '/after/lsp/'
    print(vim.fs.joinpath('', '')) -- '/'

Especially problematic if the empty segment is the first segment, as
that converts the path to an absolute path.

Solution:
Ignore empty (length of 0) path segments.

Benchmark:

    local function test(func)
      local t = vim.uv.hrtime()
      for _ = 1, 100000, 1 do
        func('', 'this/is', 'a/very/long/path', '', 'it', 'really', 'is')
      end
      print(math.floor((vim.uv.hrtime() - t) / 1e6), 'ms')
    end

- with Iter():filter() --> 370 ms
- building new segments table --> 208 ms
- with vim.tbl_filter --> 232 ms
- Instead of gsub split on `/` in all parts --> 1870 ms

2368a9edbd feat(terminal): support SGR dim, overline attributes #37997
Problem:
libvterm doesn't support parsing the dim and overline attributes, so when a program running in the embedded terminal emits one of these escape codes, we ignore it and don't surface it to the outer terminal.

Solution: tweak libvterm to add support for both attributes.

84d3bbef23 fix(map): use names like Map_key_value not Map_keyvalue
This makes little difference in practice except for extremely unlikely
ambiguities. But it looks nicer in compiler errors and stacktraces where
you see the fully expanded names

5cbb9d613b fix(startup): wait for bg detection before user config #37075
Problem:
Automatic background detection sets the background option too late,
which loads colorschemes twice and causes problems when the user's
terminal background doesn't match the default (#32109, #36211, #36416).

Solution:
Use a DA1 query to determine whether the TTY supports OSC 11. Wait for
background detection and setting to complete before processing user
config.

Note: To preserve the existing behavior as much as possible, this triggers
OptionSet manually on VimEnter (since it won't trigger automatically if
we set bg during startup). However, I'm unsure if this behavior is
truly desired given that the documentation says OptionSet is triggered
"After setting an option (except during |startup|)."

Also fixes flickering issue #28667. To check for flickering:

    nvim --clean --cmd "set termguicolors" --cmd "echo \"foo\"" --cmd "sleep 10"

On master, this gives me a black screen for 10 seconds, but on this
branch, the background is dark or light depending on the terminal
background (since the option is now set during startup rather than after
VimEnter).

f45c550f4e fix(restart): drop "-s <scriptfile>" from v:argv on :restart #38058
Problem: When nvim is started with "-s -" (read from stdin), ":restart"
drops the "-" argument but keeps "-s", leaving an orphaned "-s" in the
restarted server's argv, causing a crash.

Solution: Drop "-s" and its scriptfile argument when copying v:argv for
the restarted server. Like "-- [files…]", the scriptfile is a one-shot
startup input that should not be replayed on restart

ea5007b37f fix(lps): separate namespaces for pull/push diagnostics #37938
Problem:
Regression from b99cdd0:
Pull diagnostics (from `textDocument/diagnostic`) and push diagnostics
(from `textDocument/publishDiagnostics`) use the same namespace, which
is a problem when using language servers that publish two different sets
of diagnostics on push vs pull, like rust-analyzer (see
https://github.com/rust-lang/rust-analyzer/issues/18709#issuecomment-2551394047).

Solution:
Rename `is_pull` to `pull_id` which accepts a pull namespace instead of
just a boolean.

e63346dfe9 fix(messages): reset redirection message column at message start #38068
Problem:  Leading message newlines (not emitted with ext_messages since
          4260f73) were responsible for resetting the redirection message
          column (while the newline itself is later pruned...).
Solution: Ensure the redirection column is reset at the start of a message.
          (Instead of re-adjusting all the newline callsites which can
          themselves hopefully be pruned if ext_messages is enabled by
          default.)

37c0efb21c fix(marktree): fix edge case bug regarding changing intersections
fix #37867

This bug happens when only one end is moved between different nodes,
but the other end is also moved but within the same node.
When this happens we need the correct previous position even for the
internal move. This code shall be refactored to make the intent clearer,
(and avoid some unnecessary processing) but this is a fix for the observable
bug.

Thanks to KevinGoodsell for providing a deterministic
reproduce using fuzzing techniques.
