This removes the need for the setup_child callback which is quite
tricky as it cannot touch any memory due to vfork, and removes the
Pipe abstraction in favor of a more general UniqueFd one.
Accepter is a wrapper around a socket watcher. It always uses
EventMode::Urgent, so it will be included in pselect(2) (via
EventManager::handle_next_events()) even while we are waiting for a
(blocking) shell command. However we will not execute the command
received on this socket until after the shell command is done.
This is implemented with an early return:
void handle_available_input(EventMode mode)
{
while (not m_reader.ready() and fd_readable(sock))
m_reader.read_available(sock);
if (mode != EventMode::Normal or not m_reader.ready())
return;
so we read available data but don't close the socket.
When using this reproducer
{
sleep 1 && echo 'nop' | kak -p session
} &
kak -n -s session -e '%sh{sleep 7}'
the first "m_reader.read_available(sock);" will read "nop". Then
"m_reader.ready()" is true but the socket is still readable. This
means that pselect(2) will return it every time, without blocking.
This means that the shell manager runs a hot loop between pselect(2)
and waitpid(2).
Fix this problem demoting command socket watchers from
EventMode::Urgent. This means that we won't pselect(2) it when handling
only urgent events. Control-C still works, I'm not sure why.
Alternative fix: we could read the commands but then disable the
socket. I tried this but it seems too complex.

An assert fails from time to time after reloading fifo buffers due
to being scrolled past the last line of the buffer. A repro case was
not found but this should fix the underlying issue.
The cached WordDB/Highlighters/FifoReader are not relevant and are
better fully rebuilt than updated. This speeds up rebuilding the
WordDB of big fifo buffers such as a `git log`.
Make it possible to move the current session to a daemon one after
the fact, which is useful to ensure the session state survives client
disconnecting, for example when working from ssh.
Filename arguments to kak -c SESSION are passed to the remote sessions
as commands like
edit 'FILENAME';
but single-quotes in FILENAME are incorrectly escaped as \' instead of
being doubled-up. Fix this so kak -c SESSION "foo'bar" becomes
edit 'foo''bar';
instead of
edit 'foo\'bar';

This removes the timing dependent behaviour where `Tab` would only
display the completion menu if pressed before the prompt idle timeout
This means `exec :dc<tab>` now expands 'dc' to 'define-command'
instead of just showing the completion menu a few millis early.
ensure cursor is visible after user input except if the command
implementation opted-out. Hooks and timers should not enforce
visible cursor.
PageUp/PageDown and `<c-f>` / `<c-b>` commands still move the cursor
as this seemed a desired behaviour.
Ensure we ignore SIGHUP once the TerminalUI is gone as it will be
sent again on fork, fix the parent process terminating due to trying
to write to stdout after it was closed.
Fixes#4960
This is currently broken on various corner cases and breaks the
"master branch should be good for day to day work" implicit rule,
ongoing work to stabilize this feature will take place on the
no-cursor-move-on-scroll branch until its deemed ready.
This reverts commit 1e38045d70.
Closes#4963
Kakoune now does not touch cursors when scrolling. It checks
if either the buffer or selections has been modified since
last redraw.

RegionsHighlighter::create_region() validates the highlighter type argument
but RegionsHighlighter::create_default_region() assumes it is correct,
segfaulting from dereferencing a null pointer if the given type isn't in
the highlighter registry HashMap.
@PJungkamp reported this in https://github.com/mawww/kakoune/issues/4959
with a simple recipe to reproduce:
:add-highlighter shared/test regions
:add-highlighter shared/test/ default-region invalid highlighter
:add-highlighter window/test ref test
Validate the type argument in RegionsHighlighter::create_default_region()
in the same way as RegionsHighlighter::create_region().
The current exponential behaviour does not seem that useful, it seems
more predictible that pressing `+` twice would end up with 3 copies
of the original selections instead of 4.
Fixes#4533
Commits e49c0fb04 (unmap: fail if the mapping is currently executing,
2023-05-14) 42be0057a (map: fail if key is currently executing,
2023-06-24) fixed potential use-after-free issues. By doing so,
it broke configurations that in practice have not triggered any
crashes [1] [2].
For example with,
set -remove global autocomplete insert
hook global InsertCompletionShow .* %{
map window insert <esc> <c-o>
}
hook global InsertCompletionHide .* %{
unmap window insert <esc> <c-o>
}
The execution of the <esc> mapping triggers InsertCompletionHide fails
at unmapping. This seems legit and I don't see an obvious alternative
way to write it (InsertIdle would not be correct though it would work
in practice).
Fix the regression by allowing map and unmap again while keeping the
mappings alive until they have finished executing.
Applying map/unmap immediately seems like the most obvious semantics.
Alternatively, we could apply them in between key presses.
