nu panics when using alias 'g' for git + push.

[antoniocorbi]

Hi all,

I've got an alias for git like this:

alias g = git

And when I use it for pushing changes in any git repo, like this:

g push

I always get this error (nu panics):

thread 'main' panicked at 'internal error: span missing in file contents cache', crates/nu-protocol/src/engine/engine_state.rs:474:9
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

It doesn't panics with other git subcommands, i.e. 'pull':

g pull

Works ok.

can you do version | to md and paste it so we know what environment you're in? i thought the bug issue form forced that.
are you using any custom completions?

[antoniocorbi]

Sure! I clicked the submit button too fast!

oh, you're on the latest in linux. i'm on the windows and get the same error.

Nope, very new to nushell, don't know how to do that.
I do use starship as my prompt customizer.

[antoniocorbi]

I've just checked that starship has nothing to do with this, I mean, without the starship-prompt the error remains.
I've also experimented this error compiling myself latest nushell on a raspberry pi4 with archlinux-arm + rust 1.60.0

[fdncred]

i don't use starship and have the same error so i don't think it's invovled either.

This is happening because git push is a known external, if you remove that, it works. I'll look into the issue, I just worked on that part of the code.

Apparently this was a problem before the recent changes too. Generally aliasing known externals behaves weirdly (and incorrectly).

Thanks for the info!
I don't know if this is somehow related...as I was having this problem I dediced to define another alias for 'git push' and I did this:

alias gp  = git push

In this case I get another error when using it:

❯ gp
Error: nu::shell::external_command (https://docs.rs/nu-protocol/0.61.0/nu_protocol/enum.ShellError.html#variant.ExternalCommand)

[filaretov]

Yeah, this is related, thanks for pointing it out!

I'll take a look over the weekend, hopefully we'll get it fixed.

@antoniocorbi could you try the latest main? I think #5213 should have fixed the issue.

Hi @filaretov !

It seems to be working for me right now, nu --version yields 0.61.1 and both aliases alias g = ... and alias gp = ... are behaving as expected.

Thanks for your help and support.

[filaretov]

That's great to hear! Thanks for filing the issue and have fun with nushell.

[fdncred]

nice, let's close this then.
