Another consequence of a583fe723 ("commandline -f foo" to skip queue
and execute immediately, 2024-04-08) is that "commandline -f repaint"
will paint the prompt with the current value of $status which might be
set from a shell command in a the currently executing binding, instead of
waiting for the top-level status. This is wrong, at least historically. It
surfaces in bindings like alt-w which always paint a status value of [1]
when on single-lines commandlines.
Another regression is that a redundant repaint in a signal handler outputs
an extra prompt.
Fix both by making repaint commands go over the input queue again. This way,
they are always run with a good commandline state. There is no need to
repaint immediately because I don't think anyone has a data dependency on it
(we currently don't expose the prompt string), it's only for rendering.

Since we enable/disable terminal protocols whenever we pass terminal ownership,
tests can no longer run in parallel on the same terminal.
For the same reason, readline shortcuts in the gdb REPL will not work anymore.
As a remedy, use gdbserver, or lobby for CSI u support in libreadline.
Add sleep to some tests, otherwise they fall (both in CI and locally).
There are two weird failures on FreeBSD remaining, disable them for now

Design and implementation borrows heavily from Kakoune.
In future, we should try to implement more of the kitty progressive
enhancements.
Closes#10359
This lacks the tmux-256color terminfo entry, leading to spurious
warnings like
warning: Could not set up terminal. <= no check matches
warning: TERM environment variable set to \'tmux-256color\'. <= no check matches
warning: Check that this terminal type is supported on this system. <= no check matches
warning: Using fallback terminal type \'ansi\'. <= no check matches
Prior to this change, tmux based tests would call 'isolated-tmux' which would
initialize tmux on first call, an admitted "evil hack." Switch to requiring
an explicit call to 'isolated-tmux-start' which then defines 'isolated-tmux'
and other functions. Add some loop-until-prompt logic into
'isolated-tmux-start'. This improves reliability of the tmux tests on systems
under load; at least it makes the tests pass in the background on my Mac.
Remove the '$sleep' variable, to be replaced with 'tmux-sleep'.
The tmux-prompt test would sometimes fail because the first call was:
isolated-tmux capture-pane -p
this would run a capture-pane which would race with starting fish
itself; occasionally the pane would be empty since fish has not yet
drawn a prompt. Add a loop to give fish time to draw the prompt.
This was long overdue since the setup logic is much more complex than
the actual tests.
tmux-prompt.fish had extra logic to protect against XDG_CONFIG_HOME
with leading double double-dot. I believe this is no longer necessary
with the new test driver.
We still use our own temp dir because we want to be able to run this
independently of the test driver, This can be useful for debugging
tests. For example we can insert a "$tmux attach" command in a test,
and then run
build/fish -C 'source tests/test_functions/isolated-tmux.fish' tests/checks/tmux-bind.fish
This allows to inspect the state of the test and debug interactively.
Attaching to the terminal doesn't work when running inside littlecheck
because littlecheck consumes our output and doesn't give us a terminal.
(Maybe there's an easy way to fix that?)
In some setups (eg. macports) $tmpdir can expand to more than
100 symbols and tests fail with 'socket file name too long'
errors.
Using relative path to socket file fixes the issue.
The tmux-prompt test was failing when run more than once, because
XDG_DATA_HOME has a leading double-dot, causing the uvars file to
leak across sessions. Descend more deeply into our tmpdir to isolate
our XDG_DATA_HOME.
This reverts commit b56b230076.
which somehow made us miss repaints on uvar notifications.
The commit was a workaround for a polling bug which was later properly
fixed by 7c5b8b855 ("Use the uvar notifier pipe timestamp to avoid
excessive polling"), so it's no longer necessary.
Add a system test. If I had a better understanding of the bug I could
probably write a better test.
Fixes#8088
