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
This removes the 100 msec timeout from io_buffer_t. We no longer need to
periodically wake up to check if a command substitution is finished,
because we get explicitly poked when that happens.
io_buffer_t is used to buffer output from a command substitution, so we
can split it into arguments. Typically io_buffer_t reads from its pipe
until it gets EOF and then stops reading. However it may be that the
cmdsub ends but EOF is not delivered because the stdout of the cmdsub
escaped with a background process.
Prior to this change we would wake up every 100 msec (select timeout) to
check if the cmdsub is finished. However this 100 msec adds latency if a
background process is launched from e.g. fish_prompt.
Switch to the new poke() function. Now when the cmdsub is finished, it
pokes its item, which explicitly wakes it up. This removes the extra
latency.
Fixes#7559
In preparation for fixing #7559, add a function poke_item to fd_monitor.
fd_monitor has a list of file descriptors, and invokes a callback when an
fd becomes readable. With this change, we assign each item a unique ID and
return it when the item is added; the ID may then be used to invoke the
callback explicitly.
The idea is that we can stop reading from the pipe associated with the
cmdsub when the job is finished, even if the pipe is still open.
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.
This is mildly useful when activating virtualenvs. We had remove
these files earlier, but since there are no more false negatives from
__fish_complete_suffix it seems safe to re-add them.
