From commit b1369a52c24336da2d2d6d5dc6707a7834065d43
This adds the "REQUIRES" directive that allows specifying
preconditions for tests, which allows us to add tests that don't have
to run on all systems.
Now, I don't want to just make all tests specific to an OS or
something, but e.g. a `git` test would be a honkin' great idea, and we
can't ask everyone to have `git`!
This used to print a literal DEL character in the output for `bind`,
which wouldn't actually show up and made it hard to figure out what
the key was.
So we just escape it back to how we actually used it - `\x7f`.
Fixes#7631.
Fix 1: The --quiet flag must be at the end of the command. The way it was I would never get any status symbol in my prompt as the command failed.
Fix 2: After adding files to git, but before committing them, git status is unsorted. This gave me the output "M A M A" after `uniq`, which resulted in 4 status symbols instead of 2. Sorting them before filtering them fixed the problem.
This sometimes fails on github actions with ASAN. I am assuming that's
because the ctrl-c happens *before* the process has had a chance to
start.
So we do what we do and increase the delay.
These are a foreground and a background color. Now I see the point in
not naming them "foreground_color" and "background_color", but at
least "fg" and "bg" should do, right?
Prior to this change, histories were immortal and allocated with either
unique_ptr or just leaked via new. But this can result in races in the
path detection test, as the destructor races with the pointer-captured
history. Switch to using shared_ptr.
As mentioned in 5b706faa73, bare
`disown` has a problem: It disowns the last *existing* job.
Unfortunately, it's easy to see cases where that won't happen:
sleep 5m &
/bin/true & # will exit immediately
disown # will most likely disown *sleep*, not true
So what we do is to pass $last_pid.
In help especially this is likely to occur because many graphical
browsers fork immediately to avoid blocking the terminal (we only
added the backgrounding and disown because some weren't).
Note that it's *possible* this doesn't occur if used in the same
function, but I don't want to rely on those semantics.
It might be worth doing this as the default - see #7210.
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.
Fixes#7614
When adding a command to history, we first expand its arguments to see
if any arguments are paths which refer to files. If so, we will only
autosuggest that command from history if the files are still valid. For
example, if the user runs `rm ./file.txt` then we will remember that
`./file.txt` referred to a file, and then only autosuggest that if the file
is present again.
Prior to this change we only performed simple expansion relative to the
working directory. This change extends it to variables and tilde
expansion. For example we will now apply the same hinting for
`rm ~/file.txt`
Fixes#7582
