Ensure that multiple `-k` completions intermixed with one or more non-`-k`
completions are produced in the expected order with the order of all completions
in a single `-k` completion respected, non-`-k` completions correctly sorted and
interspersed, and the results of multiple `-k` completions in the
reverse-intuitive order (with chronologically later completions coming before
chronologically earlier `-k` counterparts), as per #9221.
This particular variant must be executed as a pexpect test since it relies on
the interactive-only `$history` to trigger the recursion. Note that recursion is
possible via other means (e.g. reading/writing a file), the usage of history
here is just one such example.
When fish runs with job control enabled, it transfers ownership of the
tty to a child process, and then reclaims the tty after the process
exits. If job control is disabled then fish does not transfer or reclaim
the tty.
It may happen that the child process creates a pgroup and then transfers
the tty to it. In that case fish will not attempt to reclaim the tty, as
fish did not transfer it. Then when fish reads from stdin it will
receive SIGTTIN instead of data.
Fix this by unconditionally claiming the tty in readline().
Fixes#9181
This starts two sleep processes and expects them to be killed on
SIGHUP.
Unfortunately, if this ever fails the second run will also fail
because it'll see the old sleep still lying around (because it'll run
for 130 seconds).
So, what we do is:
1. Keep the pids for these specific sleeps
2. Check if any of them are still running (and only fail for them)
3. Kill them from python
Fixes#9152
Curses variables like `enter_italics_mode` are secretly defined to
dereference through the `cur_term` variable. Be sure we do not read or
write these curses variables if cur_term is NULL. See #8873, #8875.
Add a regression test.
Prior to this change, if you tab-completed a token with a wildcard (glob), we
would invoke ordinary completions. Instead, expand the wildcard, replacing
the wildcard with the result of expansions. If the wildcard fails to expand,
flash the command line to signal an error and do not modify it.
Example:
> touch file(seq 4)
> echo file*<tab>
becomes:
> echo file1 file2 file3 file4
whereas before the tab would have just added a space.
Some things to note:
1. If the expansion would produce more than 256 items, we flash the command
line and do nothing, since it would make the commandline overfull.
2. The wildcard token can be brought back through Undo (ctrl-Z).
3. This only kicks in if the wildcard is in the "path component
containing the cursor." If the wildcard is in a previous component,
we continue using completions as normal.
Fixes#954.
Cancellation groups were meant to reflect the following idea: if you ran a
simple block:
begin
cmd1
cmd2
end
then under job control, cmd1 and cmd2 would get separate groups; however if
either exits due to SIGINT or SIGQUIT we also want to propagate that to the
outer block. So the outermost block and its interior jobs would share a
cancellation group. However this is more complex than necessary; it's
sufficient for the execution context to just store an int internally.
This ought not to affect anything user-visible.
Say the user has a multi-char binding (typically an escape sequence), and a
signal arrives partway through the binding. The signal has an event handler
which enques some readline event, for example, `repaint`. Prior to this
change, the readline event would cause the multi-char binding to fail. This
would cause bits of the escape sequence to be printed to the screen.
Fix this by noticing when a sequence was "interrupted" by a non-char event,
and then rotating a sequence of such interruptions to the front of the
queue.
Fixes#8628
`read` allows specifying the initial command line text. This was
text got accidentally ignored starting in a32248277f. Fix this
regression and add a test.
Fixes#8633
* fish_key_reader: Simplify default output
It now only prints the bind statement. Timing information and such is
relegated to a separate "verbose" mode.
* Adjust fish_key_reader docs
* Adjust tests
This finds the first broken component, to help people figure out where
they misspelt something.
E.g.
```
echo foo >/usr/lob/systemd/system/machines.target.wants/var-lib-machines.mount
```
will now show:
```
warning: Path '/usr/lob' does not exist
```
which would help with seeing that it should be "/usr/lib".
This allows rebinding escape in the user list without breaking e.g.
arrow keys (which send escape and then `[A` and similar, so escape is
a prefix of them).
Fixes#8428.
On macOS, the tests would often fail because calls to `pkill` would "leak"
across tests: kill processes run by other tests. This is because on macOS,
the -P argument to pkill must come before the process name. On Linux it
doesn't matter.
This improves test reliability on Mac.
Fixes#8232.
Note that this needed to have expect_prompt used in the pexpect test -
we might want to add a "catchup" there so you can just ignore the
prompt counter for a bit and pick it back up later.
This disables job control inside command substitutions. Prior to this
change, a cmdsub might get its own process group. This caused it to fail
to cancel loops properly. For example:
while true ; echo (sleep 5) ; end
could not be control-C cancelled, because the signal would go to sleep,
and so the loop would continue on. The simplest way to fix this is to
match other shells and not use job control in cmdsubs.

Today the reader exposes its internals directly, e.g. to the commandline
builtin. This is of course not thread safe. For example in concurrent
execution, running `commandline` twice in separate threads would cause a
race and likely a crash.
Fix this by factoring all the commandline state into a new type
'commandline_state_t'. Make it a singleton (there is only one command
line
after all) and protect it with a lock.
No user visible change here.
This apparently doesn't work at all under Github Actions with tsan, so let's skip it.
If anyone feels the need to dig deeper into this, have at it. I find
this distracting.
When the user presses control-C, fish marks a cancellation signal which
prevents fish script from running, allowing it to properly unwind.
Prior to this commit, the signal was cleared in the reader. However this
missed the case where a binding would set $fish_bind_mode which would
trigger event handlers: the event handlers would be skipped because of
the cancellation flag was still set. This is similar to #6937.
Let's clear the flag earlier, as soon as we it's set, in inputter_t.
Fixes#8125.
This is the last time I'm doing this before I rip these particular
tests out.
As far as I know there is no actual *problem* here, this is just
failing through a combination of macOS and Github Actions being slow
as molasses.
So it is wasting our time and therefore worse than not having these
tests at all, especially since they very rarely fail for good reasons.
We would leave some escape delay tests intact with generous timeouts, which would provide 90%
of the coverage with 10% of the hassle.
This simply checks if the parser requested exit after running any
binding scripts (in read_normal_chars).
I think this means we no longer need the `exit` bind function.
Fixes#7967.
