The builtin-buffering thing is huge and should be early in the big
ticket items, the performance improvement to completion of commands is
cool but not all that important.

Like Gold, it doesn't warn about sys_nerr, _sys_errlist, and co.
Unlike Gold, we can use this on all platforms. It's also faster than
both Gold and plain, old ld.
This was typically overridden by "too many/few arguments", but it's
actually incorrect:
sin(55
has the correct number of arguments to `sin`, but it's lacking
the closing `)`.
This is far preferable to the per-test XDG overrides that we may or may
not remember to add the next time around.
Also rename all the directories so it is clear via which variable a file
made its way into that path.
fish_user_paths is a fish-specific variable that can be persisted by
making it a universal variable or by making it a global variable set at
startup in `config.fish`.
Since it is not defined in a clean installation, a user could
inadvertently create it as `set -Ux fish_user_paths ....` the first
time, creating a horrible, ugly, self-loathing mess that will have you
chasing ghosts and bisecting for naught once fish re-imports
fish_user_paths as a *global* variable that shadows the universal one.
While that is true for any universal variable that is re-imported as a
global variable, only fish_user_paths has the potential to really screw
things up because we also re-export PATH based off of its value in turn.
This fixes up the SIGIO notifier in preparation for using it on BSD. It
removes the reliance on the signal's si_code, which is not available in
BSD, and it properly handles the BSD behavior where SIGIO is delivered on
a read even if the read returns EAGAIN.
Fix an error caused by `exec_job()` assuming a job launched with the
intention of being backgrounded would have a pgid assigned in all cases,
without considering the status of `exec_error` which could have resulted
in the job failing before it was launched into its own process group.
Fixes (but doesn't close) #7423 - that can be closed if this assertion
failure doesn't happen in any released fish versions.
This is super cheesy.
One of the most common feature requests we get is "control-r must
search", even tho just using history-search-backward via e.g. up-arrow
is perfectly capable. The only real difference is that ctrl-r search
in other shells allows editing the search term by default, while we
stop the history search and edit the new commandline in those cases.
So, since the major problem is muscle-memory on ctrl-r,
let's just use that!
This makes ctrl-r do nothing on empty commandlines, and do
history-search-backward otherwise, so the basic flow of "press ctrl-r
to start history search, enter your search term, press ctrl-r to cycle
through matches" just works (except the first ctrl-r is useless and it
doesn't show anything).
See #602.
It is apparently possible to launch fish such that its pid owns the tty,
but its pid is in a different pgroup. In that case, do not attempt to stop
with SIGTTIN; instead simply attempt to place fish in its own pgroup.
Fixes#7388
jobs -p %1 prints all processes in the first job.
fg is special because it only takes one argument. Using the last process
in the pipeline works for the cases I can think of.
Fixes#7406
We've heard news of this regressing, so let's add the test that should
have been there already (mea culpa!).
Because we now use POSIX_VDISABLE, this should also work in tandem
with ctrl-space (which sends NUL), but we can't test *that* because
some systems might not have POSIX_VDISABLE.
`complete_param_expand` knows how to handle cases like `foo=br` so we
don't need to bother sending just the `br` part. Furthermore, sending
just `br` is incorrect because we will end up replacing the entirety of
`foo=br` with the result of the completion. That is, `foo=br` will be
replaced with `bar` instead of being completed to `foo=bar`.
This switch is no longer necessary when only one command is given.
Internally completions are stored separately for each command,
so we only every print one command name per "complete" line anyway.
These aliases seem to be common, see #7389 and others. This prevents
recursion on that example, so `alias ssh "env TERM=screen ssh"` will just
have the same completions as ssh.
Checking the last token is a heuristic which hopefully works for most
cases. Users are encouraged to use functions instead of aliases.
This prevents a seemingly infinite loop in
fish -c 'alias ssh "env ssh"; complete -C "ssh "'
It still prints "maximum recursion depth exceeded", but a follow-up commit
will work around that.
Fixes#7389
