Introduce pgroup_provenance_t, a type which captures "where the pgroup
comes from." This centralizes some logic around how pgroups are
assigned, and it anticipates concurrent execution.
Just another version of the error. We still want to get a bug if it
ever triggers a *wrong* error, so we still list all the options
instead of going for `.*option:.*Z.*`.
Fixes#6554
Solaris/OpenIndiana/Illumos `rm` checks that and errors out.
In these cases we don't actually need it to be a part of $PWD as
it's just for cleanup, so we `cd` out before.

In some cases on some platforms this could clobber errno, so doing something like
aThingThatFailsWithErrno();
FLOG(category, "Some message");
wperror("something");
would print the wrong error (presumably if that category was enabled).
In our case it was our (very) old friend RHEL6 returning ESPIPE instead of EISDIR.
Fixes#6545.
At the moment the "prepend sudo" functionality always sets the cursor to
the end of the line. This changes it to restore the relative position of
the cursor.
Prior to this fix, the cancellation C++ test would mark the parser as
interactive in an effort to install interactive signal handling (so that,
for example, SIGINT would stop the job and return control to the user).
However this flag would also cause fish to attempt to save and restore tty modes
across the job. This would fail since there is no tty, and so the job would fail
with an unexpected error code.
We don't need to mark the parser as interactive, we can just remove that line.
Fixes#6539.
Use some more move semantics to reduce allocations.
Correctly handle the case where the completion is empty. For example, if
you type:
ls<tab>
we get an empty completion (since ls is already a valid command), but we
still want to show its description.
Remove some unsafe statics - these are unsafe today in weird cases where
completions might invoke complete recursively, and also will soon be
unsafe with concurrent execution.
Prior to this fix, fish was rather inconsistent in when $status gets set
in response to an error. For example, a failed expansion like "$foo["
would not modify $status.
This makes the following inter-related changes:
1. String expansion now directly returns the value to set for $status on
error. The value is always used.
2. parser_t::eval() now directly returns the proc_status_t, which cleans
up a lot of call sites.
3. We expose a new function exec_subshell_for_expand() which ignores
$status but returns errors specifically related to subshell expansion.
4. We reify the notion of "expansion breaking" errors. These include
command-not-found, expand syntax errors, and others.
The upshot is we are more consistent about always setting $status on
errors.
macOS `mktemp -d` likes to return symlinks. Guard against that possibility.
That allows the test to succeed when run directly, instead of through the
build target.
