Problem: nvim_win_set_config may merge configs despite failing to configure a
split, and without applying necessary side-effects (like setting style=minimal
options). Plus, autocommands may apply a different config after the merge,
causing side-effects to apply for an outdated config.
Solution: merge configs last, only on success. Include fields only relevant to
splits. Properly set _cmdline_offset for splits.
Maybe better to disallow _cmdline_offset for splits instead, as the pum is
relative to cmdline_row anyway? (I didn't want to change behaviour too much)
Also use expect_unchanged in an unrelated test to quash a warning.
Problem: nvim_win_set_config with style="minimal" does not take immediate effect
when a split is not moved.
Solution: don't skip nvim_win_set_config's epilogue when only a resize may be
needed. De-duplicate resize logic and remove unnecessary redraw. (win_set*_win
already handles that)

Running the test repeatedly somehow doesn't trigger the problem, but as
mentioned in #36792 a similar problem has also happened previously.
Problem: Expanded cmdline is left open after entering the cmdline again
without entering a command that emits another message (after 301c7065).
Solution: Wait for msg_show to reinstate the vim.on_key() handler.
If there was no message close the expanded cmdline.
Problem: Prompts and message text (in block mode) in the cmdline are
parsed and highlighted as if it is Vimscript.
Entering the cmdline while it is expanded can work more like
it does with UI1, where the press enter prompt is replaced
and previous messages stay on the message grid, while
subsequent messages are placed below it.
Solution: Highlight manually with string parser on lines starting with ':'.
Spoof cmdline block mode when the cmdline is entered while it
is expanded.
Problem: Previous tests for this relied on other events opening the
targets, which are not guaranteed to happen.
Solution: Open target windows when entering a new tabpage.
Problem: Calling nvim_set_hl() with url= crashes because it tries to
free arena-owned string memory.
Solution: Remove the bad free and return a validation error instead.
This reverts commit ab8371a26c.
Need to think of a different solution, which may require adding new
flags to nvim_ui_attach() (e.g. passing stdout or stderr fd).
Problem:
On FreeBSD, output written to TTY may be lost on exit.

Solution:
Call tcdrain() on stdout and stderr on exit.
This problem is only observed on FreeBSD, but it probably doesn't hurt
to do this on all platforms with termios.h. In fact using tcdrain() on
PTY slave is no-op on Linux according to Linux kernel source code.
Hyphenated language names are silently dropped when used as injections
(see #38132).
This combines the normalization of language aliases into `resolve_lang`,
and also adds the normalization of hyphens to underscores, which allows
for handling of injected language tags with hyphens in their names.
Fixes#38132.
- Use double underscores for the group targets as these targets usually
shouldn't be used directly.
- Use dash instead of underscore in the two targets that need to be used
directly. I'm not entirely sure about this, as both chars are used in
many targets, but a dash is easier to type than an underscore.
Problem: During initial "bootstrap" via lockfile synchronization, the
whole plugin specification is reconstructed from the lockfile data,
ignoring potential user changes added in the first `vim.pack.add()`.
This is enough in most situations since it is the only data needed
for actual installation.
However, this affects specification passed to `PackChanged[Pre]`
events. In particular, `data` field is missing which can be a problem
if there is a `PackChanged kind=install` hook that uses that field
(like with some kind of `build` method used during install).
And there might be different `version` set in `vim.pack.add()`.
Solution: Pass the `specs` input of the first `vim.pack.add()` down to
lockfile synchronization and use it to reconstruct plugin
specification for the to-be-installed plugin. If present among the
user's `specs`, it is used but with forced `src` from the lockfile (as
it is the one used during installation).
Note that this still has a caveat when using separate
`vim.pack.add()`, as only the specs from the first input (when the
lockfile synchronization happens) is taken into account.
Problem: 'listchars' "leadtab" not used in :list (after 9.2.0088).
Solution: Also check for "leadtab" when using :list. Fix memory leak on
E1572 if "multispace" or "leadmultispace" is set (zeertzjq).
closes: vim/vim#195575845741d69
Problem: nvim_win_get_config() does not return a window's "style".
Solution: always include it, and document `style=""`.
Always included so it can be used reciprocally with nvim_open_win() or
nvim_win_set_config(). (otherwise the config of a window with kWinStyleUnused
will not unset the kWinStyleMinimal style of another window if passed to
nvim_win_set_config, for example)
Problem: 5943a81 skips saving window options in `buflist_altfpos` for
style=minimal windows, which also prevents the window from restoring its own
options when switching buffers.
Solution: revert the change. In `get_winopts`, don't restore options from the
`WinInfo` of style=minimal windows when reusing values for a different window.
In `win_free`, clear `wi_optset` for minimal windows.
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).
closes: vim/vim#195494b30e40a1f
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).

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.

Problem: Color completion items display as plain text without visual preview
Solution: Parse RGB/hex colors from documentation and render with colored symbol ■
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
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.
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: closing a minimal float saves its style-imposed options into
buffer's wininfo, which get picked up by normal windows on :bnext.
Solution: don't save window options to wininfo for style=minimal windows.
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
when passed to readfile() (ehdgks0627, un3xploitable)
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().

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).

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.

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\\ \
```

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
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.
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).
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
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.
Problem: Not possible to know when a session will be loaded.
Solution: Add the SessionLoadPre autocommand (Colin Kennedy).

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.)
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.
