Problem: Arbitrary restriction on 'cmdheight' with ext_messages.
The 'cmdheight'-area may be desirable for the replacing
cmdline.
Solution: Allow non-zero 'cmdheight' with ext_messages.
Problem: may not be clear why failing to split causes an ":Xdo" command
to abort if 'wfb' is set.
Solution: do not return immediately if win_split fails, so E1513 is
still given. Expect both errors in the test. Also fix tests to
pass CI.

Problem: several minor 'winfixbuf' issues exist, mostly relating to the
quickfix list
Solution: address them and adjust tests. Retab and reflow a few things too.
(Sean Dewar)
Things touched include:
- Replace the semsgs with gettext'd emsgs.
- Handle window switching in ex_listdo properly, so curbuf and curwin
are kept in-sync and trigger autocommands; handle those properly.
- Don't change the list entry index in qf_jump_edit_buffer if we fail
due to 'wfb' (achieved by returning FAIL; QF_ABORT should only be used
if the list was changed).
- Make qf_jump_edit_buffer actually switch to prevwin when using `:cXX`
commands **outside** of the list window if 'wfb' is set in curwin.
Handle autocommands properly in case they mess with the list.
NOTE: previously, it seemed to split if 'wfb' was set, but do nothing
and fail if prevwin is *valid*. This behaviour seemed strange, and maybe
unintentional? Now it aligns more with what's described for the `:cXX`
commands in the original PR description when used outside a list window,
I think.
- In both functions, only consider prevwin if 'wfb' isn't set for it;
fallback to splitting otherwise.
- Use win_split to split. Not sure if there was a specific reason for
using ex_splitview. win_split is simpler and respects modifiers like
:vertical that may have been used. Plus, its return value can be checked
for setting opened_window in qf code (technically win_split_ins autocmds
could immediately close it or change windows, in which the qf code might
close some other window on failure; it's already the case elsewhere,
though).

`get_target_property(<var> ...)` sets `<var>` to `<var>-NOTFOUND` if the
property doesn't exist for the given target. Detect this situation to
avoid adding various `-Dprop-NOTFOUND` and `-Iprop-NOTFOUND` to the

Problem: Internal error or crash when passing invalid position to

Solution: Give an error for invalid position (zeertzjq).

Problem: problem with writing extended attributes on failure
Solution: Change return type to ssize_t and check listxattr's return
value correctly on failure (Paul Tagliamonte)
The existing logic will return when the listxattr call returns with the
errno set to ENOTSUP (or a size of 0 bytes), without checking to see if
listxattr actually failed. listxattr can fail with at least E2BIG,
ENOTSUP, ERANGE, or anything that `stat(2)` can fail with (in my case;
ENOENT from stat).
The returned size is stored to a size_t, but the return type is a
ssize_t. On failure, listxattr returns -1, which will get translated to
size_t's MAX. If the listxattr call failed with anything other than
ENOTSUP, this triggers a request for size_t MAX bytes.
This means that, if the listxattr call fails with anything other than
ENOTSUP on save, vim will error with
`E342: Out of memory! (allocating 18446744073709551615 bytes)`
(keen observers will note 18446744073709551615 is 0xffffffffffffffff)
In reality, this is likely masking a different (usually filesystem?)
error -- but at least it's an error being pushed to the user now, and we
don't try to allocate size_t MAX bytes.
I've opted to change the type that we store listxattr to from size_t to
ssize_t, to match listxattr(2)'s signature, and to check for the -1
return value. Additionally, I've removed the errno check -- if we get a
listxattr failure for any reason, we may as well bail without trying;
it's not like we can even recover.

runtime(java): Recognise string templates (vim/vim#14150)
As this is encouraged in the referenced JEPs, "to visually
distinguish a string template from a string literal, and
a text block template from a text block", the default
colours for java\%[Debug]StrTempl are made distinct from
java\%[Debug]String.
According to §3.2 Lexical Translations (JLS, c. 1996 or any
more recent version), line terminators, white space, and
comments are discarded before tokens are accepted. Since
a template expression comprises a template processor, a dot,
and a template, it may be visually appealing to break up
its head across a few lines whenever its tail already spans
multiple lines. Curiously, no allowance for it is made in
the distributed tests for OpenJDK 21; the proposed regexp
patterns take in consideration a line terminator and white
space after a dot.

This reverts PR #27793.
On second thought, this solution may still crash, because it can leave a
window with a NULL buffer if there are autocommand windows or if closing
a floating window fails. It also makes close_last_window_tabpage() more
complicated, so revert it.
Problem: Crash in WinClosed after BufUnload closes other windows
Solution: Don't trigger WinClosed if the buffer is NULL (zeertzjq)
Now win_close_othertab() doesn't trigger any autocommands if the buffer
is NULL, so remove the autocmd blocking above (which was added not long
ago in patch v9.0.0550) for consistency.
Also remove an unreachable close_last_window_tabpage() above:
- It is only reached if only_one_window() returns TRUE and last_window()
returns FALSE.
- If only_one_window() returns TRUE, there is only one tabpage.
- If there is only one tabpage and last_window() returns FALSE, the
one_window() in last_window() must return FALSE, and the ONE_WINDOW
in close_last_window_tabpage() must also be FALSE.
- So close_last_window_tabpage() doesn't do anything and returns FALSE.
Then the curtab != prev_curtab check also doesn't make much sense, and
the only_one_window() can be replaced with a check for popup and a call
to last_window() since this is a stricter check than only_one_window().

Cherry-pick test_expand.vim change from patch 9.0.1257.
Problem: Crash on exit with EXITFREE and using win_execute().
Solution: Also save and restore tp_topframe. (issue vim/vim#9374)
dab17a0689
Couldn't repro the crash in the test, but I only care about this patch so
switch_win sets topframe properly for win_split_ins in nvim_open_win and
nvim_win_set_config.
Add a test using nvim_win_call and :wincmd, as I couldn't repro the issue via
nvim_open_win or nvim_win_set_config (though it's clear they're affected by this
patch).
That said, at that point, could just use {un}use_tabpage inside switch_win
instead, which also updates tp_curwin (though maybe continue to not set it in
restore_win). That would also fix possible inconsistent behaviour such as:
:call win_execute(w, "let curwin_nr1 = tabpagewinnr(1)")
:let curwin_nr2 = tabpagewinnr(1)
Where it's possible for curwin_nr1 != curwin_nr2 if these commands are run from
the 1st tabpage, but window "w" is in the 2nd (as the 1st tabpage's tp_curwin
may still be invalid). I'll probably PR a fix for that later in Vim.

Problem: nvim_win_set_config does not update the tp_curwin of win's original
tabpage when moving it to another.
Solution: update it if win was the tp_curwin. Add a test.
Problem: illegal memory access when completing with invalid bytes.
Solution: Avoid going over the end of the completion text.
vim/vim@4b28ba3
Co-authored-by: Bram Moolenaar <Bram@vim.org>
Problem Description: In ex_mode, the default_grid.chars are not allocated, and subsequently,
the w_grid.target in curwin is not allocated to default_grid in update_screen. This leads to
a null pointer crash when the completion function is executed in ex_mode.
Solution: Set full_screen when in ex_mode to ensure that default_grid is allocated.
Problem: :close may cause Nvim to quit if an autocommand triggered when
closing the buffer closes all other non-floating windows and
there are floating windows.
Solution: Correct the check for the only non-floating window.
Its corresponding test in Vim is in test_popupwin.win, so having it in
the middle of test_window_cmd.vim is strange, and it is now covered by
tests in ui/float_spec.lua anyway.
Problem: nvim_win_set_config does not update statuslines after removing a split.
Solution: call last_status.
Didn't realize this was missing in the original nvim_win_set_config for splits
PR.
As it can only be done for the current tabpage, do it if win_tp == curtab;
enter_tabpage will eventually call last_status anyway when the user enters
another tabpage.
Problem: there are new ways to escape textlock or break the cmdwin in
nvim_win_set_config and nvim_tabpage_set_win.
Solution: fix them. Use win_goto to check it in nvim_tabpage_set_win and use the
try_start/end pattern like with similar functions such as nvim_set_current_win
(which uses the existing msg_list, if set).
Careful not to use `wp->handle` when printing the window ID in the error message
for nvim_tabpage_set_win, as win_goto autocommands may have freed the window.
On a related note, I have a feeling some API functions ought to be checking
curbuf_locked...
Problem: nvim_win_set_config does not handle failure in win_split_ins properly
yet, which can cause all sorts of issues. Also nvim_open_win and
nvim_win_set_config do not set the error message to the one from win_split_ins.
Solution: handle failure by undoing winframe_remove, like in win_splitmove.
Make sure autocommands from switching to the altwin fire within a valid window,
and ensure they don't screw things up. Set the error message to that of
win_split_ins, if any.
Also change a few other small things, including:
- adjust win_append to take a tabpage_T * argument, which is more consistent
with win_remove (and also allows us to undo a call to win_remove).
- allow winframe_restore to restore window positions. Useful if `wp` was in a
different tabpage, as a call to win_comp_pos (which only works for the current
tabpage) after winframe_restore should no longer be needed.
Though enter_tabpage calls win_comp_pos anyway, this has the advantage of
ensuring w_winrow/col remains accurate even before entering the tabpage
(useful for stuff like win_screenpos, if used on a window in another tabpage).
(This change should probably also be PR'd to Vim later, even though it doesn't
use winframe_restore for a `wp` in a different tabpage yet).
Problem: heap-use-after-free in win_splitmove if Enter/Leave
autocommands from win_split_ins immediately closes "wp".
Solution: check that "wp" is valid after win_split_ins.

Problem: infinite loop in win_update with 'smoothscroll' set when

Test_window_split_no_room changes were already cherry-picked earlier.
Problem: can switch windows while textlocked via f_win_gotoid and

Solution: Check text_or_buf_locked in f_win_splitmove()
(Sean Dewar)
While at it, call text_or_buf_locked() in f_win_gotoid() instead of testing for
cmdwin_type() (which text_buf_locked() does and in addition will also verify
that the buffer is not locked).

Problem: saving and restoring all frames to split-move is overkill now
that WinNewPre is not fired when split-moving.

Adjust winframe_restore to account for Nvim's horizontal separators when the

0fd44a5ad8
Omit WSP_FORCE_ROOM, as it's not needed for Nvim's autocmd window, which is
floating. Shouldn't be difficult to port later if it's used for anything else.
Make win_splitmove continue working for turning floating windows into splits.
Move the logic for "unfloating" a float to win_split_ins; unlike splits, no
changes to the window layout are needed before calling it, as floats take no
room in the window layout and cannot affect the e_noroom check.
Add missing tp_curwin-fixing logic for turning external windows into splits, and
add a test.
NOTE: there are other issues with the way "tabpage independence" is implemented
for external windows; namely, some things assume that tp_curwin is indeed a
window within that tabpage, and as such, functions like tabpage_winnr and
nvim_tabpage_get_win currently don't always work for external windows (with the
latter aborting!)
Use last_status over frame_add_statusline, as Nvim's last_status already does
this for all windows in the current tabpage. Adjust restore_full_snapshot_rec to
handle this.
This "restore everything" approach is changed in a future commit anyway, so only
ensure it's robust enough to just pass tests.
Keep check_split_disallowed's current doc comment, as it's actually a bit more
accurate here. (I should probably PR Vim to use this one)
Allow f_win_splitmove to move a floating "wp" into a split; Nvim supports this.
Continue to disallow it from moving the autocommand window into a split (funnily
enough, the check wasn't reachable before, as moving a float was disallowed),
but now return -1 in that case (win_splitmove also returns FAIL for this, but
handling it in f_win_splitmove avoids us needing to switch windows first).
Cherry-pick Test_window_split_no_room fix from v9.1.0121.
Update nvim_win_set_config to handle win_split_ins failure in later commits.
Problem: nvim_open_win blocking all win_set_buf autocommands when !enter &&
!noautocmd is too aggressive.
Solution: temporarily block WinEnter/Leave and BufEnter/Leave events when
setting the buffer. Delegate the firing of BufWinEnter back to win_set_buf,
which also has the advantage of keeping the timing consistent (e.g: before the
epilogue in enter_buffer, which also handles restoring the cursor position if
autocommands didn't change it, among other things). Reword the documentation for
noautocmd a bit.
I pondered modifying do_buffer and callees to allow for BufEnter/Leave being
conditionally disabled, but it seems too invasive (and potentially error-prone,
especially if new code paths to BufEnter/Leave are added in the future).
Unfortunately, doing this has the drawback of blocking ALL such events for the
duration, which also means blocking unrelated such events; like if window
switching occurs in a ++nested autocmd fired by win_set_buf. If this turns out
to be a problem in practice, a different solution specialized for nvim_open_win
could be considered. :-)
Problem: currently, for splits, nvim_win_set_config accepts win without any of
split or vertical set, which has little effect and seems error-prone.
Solution: require at least one of split or vertical to also be set for splits.
Also, update nvim_win_set_config docs, as it's no longer limited to just
floating and external windows.
