A weird interaction between grouped short options and our weird option
parsing that puts unknown options back:
```
echo "-n foo"
```
would see the `-n`, turn off printing newlines, interpret the " " as
another grouped short option, see that there is no short option for
space and put the entire token back on the arguments pile.
So it would print "-n foo" *without a newline*.
Fix this by keeping an old state of the options around and reverting
it when putting options back.
The alternative is *probably* to forbid the " " short option in
wgetopt, then check if an option group contains it and error out, but
this should only really be a problem in `echo` because that is,
AFAICT, the only thing that puts the options back.

This adds a test to ensure that if a long running background process is
launched from a command substitution, that process does not cause the
cmdsub to hang. That could easily happen if we just wait for the pipe to
close; this is verifying that we are also checking for the job to complete.
Prior to this change, `fish_private_mode` worked by just suppressing
history outright. With this change, `fish_private_mode` can be toggled on
and off. Commands entered while `fish_private_mode` is set are stored but
in memory only; they are not written to disk.
Fixes#7590Fixes#7589
Don't go into implicit interactive mode without ever executing
anything - not even `exit` or reacting to ctrl-d. That just renders
the shell useless and unquittable.
It was always a bit ridiculous that argparse required `X-longflag` if
that "X" short flag was never actually used anywhere.
Since the short letter is for getopt's benefit, we can hack around
this with our old friend: Unicode Private Use Areas.
We have a counter, starting at 0xE000 and going to 0xF8FF, that counts
up for all options that don't have a short flag and provides one. This
gives us up to 6400 long-only options.
6.4K should be enough for everybody.
Prior to this change, a glob like `**/file.txt` would only match
`file.txt` in subdirectories; the `**` must match at least one directory.
This is historical behavior.
With this change we move a little closer to bash's implementation by
allowing a literal `**` segment to match in the current directory. That
is, `**/foo` will match both `foo` and `bar/foo`, while `b**/foo` will
only match `bar/foo`.
Fixes#7222.
Before running a command, or before importing a command from bash history,
we perform error checking. As part of error checking we expand commands
including variables and globs. If the glob is very large, like `/**`, then
we could hang expanding it.
One fix would be to limit the amount of expansion from the glob, but
instead let's just not expand command globs when performing error checking.
Fixes#7407
This would tell you a function was "Defined in - @ line 1" for every
function defined via `source`.
Really, ideally we'd figure out where the *source* call was, but that'
much more complicated, so we just give a comprehensible message.
This matches what we do in --profile's output:
```
> source /home/alfa/.config/fish/config.fish
--> set -gx XDG_CACHE_HOME /home/alfa/.cache
--> set -gx XDG_CONFIG_HOME /home/alfa/.config
--> set -gx XDG_DATA_HOME /home/alfa/.local/share
```
instead of
```
+ source /home/alfa/.config/fish/config.fish
+++ set -gx XDG_CACHE_HOME /home/alfa/.cache
+++ set -gx XDG_CONFIG_HOME /home/alfa/.config
+++ set -gx XDG_DATA_HOME /home/alfa/.local/share
```
This increases a 100ms timeout to 200ms, because we've hit it on
Github Actions:
```
INPUT 3904.65 ms (Line 223): set -g fish_escape_delay_ms 100\n
OUTPUT +1.74 ms (Line 224): \rprompt 25>
INPUT +0.71 ms (Line 230): echo abc def
INPUT +0.57 ms (Line 231): \x1b
INPUT +0.57 ms (Line 232): t\r
OUTPUT +2.41 ms (Line 234): \r\ndef abc\r\n
OUTPUT +1.63 ms (Line 234): \rprompt 26>
INPUT +0.75 ms (Line 239): echo ghi jkl
INPUT +0.57 ms (Line 240): \x1b
INPUT +134.98 ms (Line 242): t\r
```
In other places it decreases sleeps where we just wait for a timeout to elapse, in which case we don't need much longer than the timeout.
And again clang-format does something I don't like:
- if (found != end && std::strncmp(found->name, name, len) == 0 && found->name[len] == 0) return found;
+ if (found != end && std::strncmp(found->name, name, len) == 0 && found->name[len] == 0)
+ return found;
I *know* this is a bit of a long line. I would still quite like having
no brace-less multi-line if *ever*. Either put the body on the same
line, or add braces.

E.g. if we do `string match -q`, and we find a match, nothing about
the input can change anything, so we quit early.
This is mainly useful for performance, but it also allows `string`
with `-q` to be used with infinite input (e.g. `yes`).
Alternative to #7495.
Currently a bit limited, unfortunately printf's `%a` specifier is
absolutely unreadable.
So we add `hex` and `octal` with `0x` and `0` prefixes respectively,
and also take a number but currently only allow 16 and 8.
The output is truncated to integer, so scale values other than 0 are
invalid and 0 is implied.
The docs mention this may change.
The '--import' flag was used for importing named capture groups, but it
was decided to always import them unconditionally. This flag was causing
the tests to fail.
Prior to this fix, when key binding is a script command (i.e. not a
readline command), fish would run that key binding using fish's shell
tty modes. Switch to using the external tty modes. This re-fixes
issue #2214.
With the upcoming fix to place the tty in external-proc mode, add a sleep
which resolves a race between emitting a newline and restoring it to shell
mode.
Prior to this change, when a process resumes because it is brought back
to the foreground, we would reset the terminal attributes to shell mode.
This fixed#2114 but subtly introduced #7483.
This backs out 9fd9f70346, re-introducing #2114 and re-fixing #7483.
A followup fix will re-fix #2114; these are broken out separately for
bisecting purposes.
Fixes#7483.
I *think* this might sometimes (on CI) be eating the prompt, so that the actual `prompt`
part of `expect_prompt` doesn't find anything.
On Github Actions we see things like:
```
Testing file pexpects/generic.py ... Failed to match pattern: prompt 5
generic.py:35: timeout from expect_prompt("echo .history.*")
[...]
OUTPUT +1.08 ms (Line 31): \rprompt 4>
INPUT +0.35 ms (Line 34): echo $history[1]\n
OUTPUT +1.58 ms (Line 35): echo $history[1]\r\necho $history[1]\r\n⏎ \r⏎ \r\rprompt 5>
```
so the prompt *is* printed, it's just not correctly matched.
Apparently on macOS SIGTSTP (from control-Z) causes `read()` to return
EINTR.
This means `cat | cat` will exit as soon as it's backgrounded and
brought back.
So instead we use `sleep`, which won't read(), and therefore is
impervious to these puny attacks.
See discussion in #7447.
The classic mistake: Some of these have a bit of a delay, but it's supposed to
be *under* the timeout, so it needs to be *shorter* not longer to
increase the slack.
We just had the following output on Github Actions:
INPUT +0.94 ms (Line 34): echo ghi jkl
INPUT +0.72 ms (Line 35): \x1b
INPUT +63.12 ms (Line 37): t\r
The default escape delay is 30ms, that had 60ms between an escape and
a tab, so it missed it.
So: We have to increase the delay for CI's benefit. Let's try with
80ms, because otherwise we'd have to bump up other timeouts and the
bind tests take long enough as it is.
