Problem: WinNew and win_enter autocommands can delete the target buffer to
switch to, causing a heap-use-after-free.
Solution: store a bufref to the buffer, check it before attempting to switch.
Problem: if switch_win{_noblock} fails to restore the old curwin after WinNew
(e.g: it was closed), wp will become the new curwin, but win_set_buf enter
events would still be blocked if !enter && !noautocmd.
Solution: fire them, as we've actually entered the new window.
Note: there's a problem of switch_win{_noblock} failing to restore the old
curwin, leaving us in wp without triggering WinEnter/WinLeave, but this affects
all callers of switch_win{_noblock} anyways. (It's also not clear how WinLeave
can be called if the old curwin was closed already).
Problem: BufWinEnter is not fired when not entering a new window, even when a
different buffer is specified and buffer-related autocommands are unblocked
(!noautocmd).
Solution: fire it in the context of the new window and buffer. Do not do it if
the buffer is unchanged, like :{s}buffer.
Be wary of autocommands! For example, it's possible for nvim_win_set_config to
be used in an autocommand to move a window to a different tabpage (in contrast,
things like wincmd T actually create a *new* window, so it may not have been
possible before, meaning other parts of Nvim could assume windows can't do
this... I'd be especially cautious of logic that restores curwin and curtab
without checking if curwin is still valid in curtab, if any such logic exists).
Also, bail early from win_set_buf if setting the temp curwin fails; this
shouldn't be possible, as the callers check that wp is valid, but in case that's
not true, win_set_buf will no longer continue setting a buffer for the wrong
window.
Note that pum_create_float_preview also uses win_set_buf, but from a glance,
doesn't look like it properly checks for autocmds screwing things up (win_enter,
nvim_create_buf...). I haven't addressed that here.
Also adds some test coverage for nvim_open_win autocommands.
Closes#27121.
Problem: win_set_config should have the observable effect of moving an existing
window to another place, but instead fires autocommands as if a new window was
created and entered (and does not fire autocommands reflecting a "return" to the
original window).
Solution: do not fire win_enter-related autocommands when splitting the window,
but continue to fire them when entering the window that fills the new space when
moving a window to a different tabpage, as the new curwin changes.
Also, remove "++once" from the WinEnter autocmd in the other test, as omitting
it also crashed Nvim before this fix.
Problem: win_enter autocommands can close new_curwin, crashing if it was the
last window in its tabpage after removing win, or can close parent, crashing
when attempting to split it later.
Solution: remove win first, check that parent is valid after win_enter.
NOTE: This isn't actually quite right, as this means win is not in the window
list or even has a frame when triggering enter autocommands (so it's not
considered valid in the tabpage). This is addressed in later commits.

`snprintf`'s second parameter should be no greater than the number of
remaining bytes in the allocated object. We can see that this was off
by one, because in the simple case where `tail == tempname` (for a file
in the current directory), `rename_with_tmp` was passing `MAXPATHL + 2`
for an object allocated with a size of only `MAXPATHL + 1`.
Introduced in 5f1a153831.
Setting the label `ci:skip-news` will skip the job. This is useful for
maintainers to indicate to contributors that a feature isn't big enough
to warrant a news entry, or for contributors who dislike red CI even if
there's nothing wrong.
Also change label `ci-s390x` to `ci:s390x`; this way it'll be easier to
see that `ci:` are a subcategory of labels that affect CI in some way.
Just some basic spring cleaning.
In the distant past, not all UI:s where remote UI:s. They still aren't,
but both of the "UI" and "UIData" structs are now only for remote UI:s.
Thus join them as "RemoteUI".

On exit, pty_process_close() may be called after pty_process_finish1()
but before start_wait_eof_timer(), in which case the timer shouldn't be
started because pty_process_close() has already closed it.

Before, we needed to always pack an entire msgpack_rpc Object to
a continous memory buffer before sending it out to a channel.
But this is generally wasteful. it is better to just flush
whatever is in the buffer and then continue packing to a new buffer.
This is also done for the UI event packer where there are some extra logic
to "finish" of an existing batch of nevents/ncalls. This doesn't really
stop us from flushing the buffer, just that we need to update the state
machine accordingly so the next call to prepare_call() always will
start with a new event (even though the buffer might contain overflow
data from a large event).
Problem: can only call getregion() for current buffer
Solution: Allow to retrieve selections from different buffers

Problem: null pointer member access in ui_client_start_server if
channel_job_start returns NULL.
Solution: check for it, return 0 in that case (which is already used to indicate
failure and is handled by main).
Happened on Linux when trying to run Nvim in an old gdbserver instance after having
rebuilt Nvim since. This gave E903 (the nvim binary was deleted, so " (deleted)" appears
as a suffix in the `v:progpath`, making it invalid), then ASAN complains due to the NPD;
instead it now then prints "Failed to start Nvim server!", as expected.

runtime(java): Recognise text blocks (vim/vim#14128)
Also, accept as valid the space escape sequence `\s`.
Also, consistently use the claimed `javaDebug` prefix for
syntax group definitions kept under `g:java_highlight_debug`.
Since `javaStringError` is commented out for its generality,
let's comment out `javaDebugStringError`, its copy, as well.

Xcode does not allow having multiple targets depend on a custom command.
This limitation severely hinders its usability and complying with it
would likely require extensive refactoring and boilerplate. It makes
more sense to simply refer users to use "Ninja" or "Unix Makefiles"
instead.
