This teaches the reader fast-path to use self-insert-notfirst, allowing
it to handle spaces. This greatly increases the performance of paste by
reducing redraws.
Fixes#6603. Somewhat improves #6704
This adds basic support for self-insert-notfirst. When we see a
self-insert-nonempty char event, we kick it back to the outer loop,
which only inserts the character if the cursor is not at the beginning.
This adds a new readline command self-insert-notfirst, which is
analogous to self-insert, except that it does nothing if the cursor
is at the beginning. This will serve as a higher-performance implementation
for stripping leading spaces on paste.
bbc3fecbe introduced a regression where support for 256 color was not
detected on xterm-like terminals that did not define the TERM_PROGRAM
env variable. Almost no terminal on linux define this variable.
f8ba0ac5bf introduced a bug where INT handlers would themselves be
cancelled, due to the signal. Defer processing handlers until the
parser is ready to execute more fish script.
Fixes the interactive case of #6649.
55e3270 introduced a regression where we would remove all completed
jobs. But jobs that want to print a status message get skipped, so
the status message (and associated event handlers) might not get run.
Fix this by making it explicit which jobs are safe to process, and which
should be skipped.
Fixes#6679.
Which happened when starting the selection at the end of the commandline.
In this case, selections still interact weirdly with autosuggestions (the
first character of the suggestion appears to be part of the selection
when it's not).

(cherry-picked from commit 99851c09b3)
Appending to an fd doesn't really make sense, but we allowed the
syntax previously and it was actually used.
It's not too harmful to allow it, so let's just do that again.
For the record: Zsh also allows it, bash doesn't.
Fixes#6614
(cherry picked from commit aba900a71f)
When building fish-shell with the macOS 10.12 SDK, <sys/proc.h> does not
include <sys/time.h> but references `struct itimerval`. This causes a
compilation failure if we don't import <sys/time.h> ourselves.
This was previously masked by an import of <sys/sysctl.h>, which was
removed in fc0c39b6fd.
(cherry picked from commit 47aeaa1535)
This was lost in 35671dd9f0.
Even tho we plan to drop caret redirection, while it's there it should
fully work.
Fixes#6591.
(cherry picked from commit 13b470af07)
Glob ordering is used in a variety of places, including figuring out
conf.d and really needs to be stable.
Other ordering, like completions, is really just cosmetic and can
change if it makes for a nicer experience.
So we uncouple it by copying the wcsfilecmp from 3.0.2, which will
return the ordering to what it was in that release.
Fixes#6593
(cherry picked from commit f053cd27c6)
The `function --on-job-exit caller` feature allows a command substitution
to observe when the parent job exits. This has never worked very well - in
particular it is based on job IDs, so a function that observes this will
run multiple times. Implement it properly.
Do this by having a not-recycled "internal job id".
This is only used by psub, but ensure it works properly none-the-less.

Backport of 6bf9ae9aebFixes#6613
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.
Fixes#6564
Sometimes we must spawn a new thread, to avoid the risk of deadlock.
Ensure we always spawn a thread in those cases. In particular this
includes the fillthread.
complete -C'echo $HOM ' would complete $HOM instead of a new token.
Fixes another regression introduced in
6fb7f9b6b - Fix completion for builtins with subcommands
64 is too low (it's actually reachable), and every sensible system should have a limit above
this.
On OpenBSD and FreeBSD it's ULONG_MAX, on my linux system it's 61990.
Plus we currently fail by hanging if our limit is reached, so this
should improve things regardless.
On my linux system _POSIX_THREAD_THREADS_MAX works out to 64 here,
which is just too low, even tho the system can handle more.
Fixes#6503 harder.
This commit recognizes an existing pattern: many operations need some
combination of a set of variables, a way to detect cancellation, and
sometimes a parser. For example, tab completion needs a parser to execute
custom completions, the variable set, should cancel on SIGINT. Background
autosuggestions don't need a parser, but they do need the variables and
should cancel if the user types something new. Etc.
This introduces a new triple operation_context_t that wraps these concepts
up. This simplifies many method signatures and argument passing.
When executing a buffered block or builtin, the usual approach is to
execute, collect output in a string, and then output that string to
stdout or whatever the redirections say. Similarly for stderr.
If we get no output, then we can elide the outputting which means
skipping the background thread. In this case we just mark the process as
finished immediately.
We do this in multiple locations which is confusing. Factor them all
together into a new function run_internal_process_or_short_circuit.
