6902459566 was an attempt to not print
$status twice in the prompt. As a result we print $pipestatus but
not $status, which /usually/ is the same as $pipestatus[-1] --- unless
the builtin "not" is used, which inverts the $status of a job (it does
not alter $pipestatus).
As a result, the default prompt prints unexpected status codes:
~ > not false
~ [1]> not true
~ > not true | true
~ > not false | false
~ [1|1]>
This commit reintroduces printing of $status after $pipestatus, but only
if it is different from $pipestatus[-1].
Additionally, we only print anything at all if the $status is nonzero,
to avoid confusing output on `not false | false`
~ > not false
~ > not true
~ [0] 1> not true | true
~ [0|0] 1> not false | false
~ >
I think this is closer to users' expectations for those cases; they should
not have to think about this implementation detail of the not-statement.
This switches bufferfills from using an exclusively-owned thread, to
sharing an fd_monitor. This allows multiple bufferfills to all use the same
thread.
fd_monitor is a new class which can monitor a set of fds, waiting for them
to become readable. When an fd becomes readable, a callback is invoked.
Timeouts are also supported.
This is intended to replace the "bufferfill" threads. Rather than one
thread per bufferfill, we will have a single fd_monitor which can service
multiple bufferfills. This helps today with nested command substitutions,
and will help in the future with concurrent execution.
* Replace multiple calls to `tail` and `string` with a single `string
replace` execution
* Dynamically generate list of available benches, bins, and tests for
`--bench`, `--bin`, and `--test` switches

This makes two changes:
1. Remove the 'brace_text_start' idea. The idea of 'brace_text_start' was
to prevent emitting `BRACE_SPACE` at the beginning or end of an item. But
we later strip these off anyways, so there is no apparent benefit. If we
are not doing brace expansion, this prevented emitting whitespace at the
beginning or end of an item, leading to #6564.
2. When performing brace expansion, only stomp the space character with
`BRACE_SPACE`; do not stomp newlines and tabs. This is because the fix in
came from a newline or tab literal, then we would have effectively
replaced a newline or tab with a space, so this is important for #6564 as
well. Moreover, it is not easy to place a literal newline or tab inside a
brace expansion, and users who do probably do not mean for it to be
stripped, so I believe this is a good change in general.

fish has some unprincipled code that attempts to tcsetpgrp() to own the
terminal before running a builtin; this was added because 'read' might
want to read from the terminal. I added this code before fully
understanding how process groups and terminals work. A better fix would
be to ensure that fish is marked as the pgroup leader in the job when
the builtin is the first process in the job, and we do that now.
Courageously back out the changes to grab the terminal; see #5147 and
also #5133.
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.*`.

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.

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.

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.
