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)
Problem:
helptag.html is used to search for the online help documentation of a
specified tag. The previous URL was `/doc/user/helptag.html` but that
switched to `/doc/user/helptag/` in
https://github.com/neovim/neovim.github.io/pull/437. The alias of the
.html page was added to all other doc pages but forgotten for the
helptag.html page
Solution:
Add the alias to the helptag.html page too
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).
using the GNU compiler we just get a bunch of const warnings we can fix.
clang, however, gets really upset that the standard library suddenly
starts using a lot of c11 features, despite us being in -std=gnu99 mode.
Basically, _GNU_SOURCE which we set is taken as a _carte blanche_ by the
glibc headers to do whatever they please, and thus we must inform clang
that everything is still OK.
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.
Problem: byteidx_common() and f_utf16idx() are calling ptr2len() twice
per iteration, instead of reusing the already computed clen.
Solution: Reuse clen for pointer advancement in both functions

Problem: 'listchars' "leadtab" not used in :list (after 9.2.0088).

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.
Previous implementation used a full sort but this is unnecessary. Pairs
do not need to be processed in id-order, all that we did was make
"start" and "end" marks find each other. This can be done with a hash
table instead. The "grow only" khash_t mentioned in the TODO is
the since long merged #249855970157e refactor with dense value array,
to not regress on memory locality.
Problem: The has() function is slow because it performs a linear scan
of the feature list for every call.
Solution: Move common runtime checks and the patch-version parser to the
beginning of the f_has() function (Yasuhiro Matsumoto).

Problem: "leadtab" behavior inconsistent on line with only TABs

closes: vim/vim#195494b30e40a1f
Problem: cannot display tabs for indentation
Solution: Add the "leadtab" value to the 'listchars' option to

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.
Example test failure on CI:

Problem: When z= fails due to no word being found, 'spelllang' being

instead of returning early (Luuk van Baal).

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:
When cross-compiling, `$<TARGET_FILE:nlua0>` resolves to the target
binary, which cannot run on the host machine during the build process.
Solution:
Allow passing a host native nlua0 binary via
`-DNLUA0_HOST_PRG=/path/to/nlua0` when cross-compiling, so code
generation can run correctly on the host.
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: 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:
Descriptions of plugins often contain taglinks which are generally
concealed. This misaligns them by 2 characters with descriptions that
don't have a taglink in them.
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:
```
myplugin.txt lsp is cool
myplugin.txt this is a nice plugin
```
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.
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
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: Inefficient use of list_append_string()
Solution: Pass string length to list_append_string() where it is known
(John Marriott).

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.

fixes#37586
when doing `packadd mypackage` up to two exact paths are added
to &rtp. Instead of recalculating runtime_search_path from scratch,
we can "just" splice these two paths in
This is simple in theory, but get complicated in practice as
"after" dirs do exist and need some wrangling.
Echasnovski did some benchmarking, to show that this reduces overhead
of a init.lua configuration style where separate `packadd!` calls are
used spread out during the config. In addition, "batched" addition
(either using "start" packages or packadd! a lot of opt packages at
once) does not regress.
A theoretical simplification could be to NEVER explicitly add "after"
dirs to &rtp, but implicitly add all existing "after" dirs in reverse
order when calculating the effective run time path. This might be tricky
to do without breaking 12 tpope plugins again tho.
We might also instead consider solutions where &rtp remains fully expanded but no longer is the main source of truth. But this is all post 0.12 work. This PR is an alright stopgap to make 0.12 fully support intended use cases of vim.pack.add() .
Problem:
- `:args` and `argv()` can change after startup.
- `v:arg` includes options/commands, not just files.
- Plugins (e.g. Oil) may rewrite directory args.
Solution:
- New read-only var `v:argf`: snapshot of file/dir args at startup.
- Unaffected by `:args` or plugins.
- Unlike `v:argv`, excludes options/commands.
- Paths are resolved to absolute paths when possible
Example:
nvim file1.txt dir1 file2.txt
:echo v:argf
" ['/home/user/project/file1.txt', '/home/user/project/dir1', '/home/user/project/file2.txt']
Problem: Newlines emitted with ext_messages intended to position
the message/prompt on the message grid.
Solution: Don't emit these newlines with ext_messages, followup to 4260f73e.
