borg list: error on non-existent path

[WilliamDEdwards]

When listing archive contents with borg list, and specifying a non-existent path, the command exits with RC 0. I would expect an error to be raised.

TBF: whether a path doesn't exist is easy to detect, because Borg simply returns no contents at all. While for an empty path, the path itself is returned.

What borg version(s)?
Is the repo local or remote?

borg list REPO?
or
borg list REPO::ARCHIVE?

[WilliamDEdwards]

What borg version(s)?

1.2.4

AFAICS, this is not version-specific.

Is the repo local or remote?

Tested both.

[WilliamDEdwards]

Here's what I did in my Python library to work around this: CyberfusionIO/python3-cyberfusion-borg-support@7b0c0d3

[ThomasWaldmann]

Can you add a short reproducer / demo script to your top post that shows the problem?

[WilliamDEdwards]

Done.

[ThomasWaldmann]

IMHO, that's not a bug.

If a path pattern matches N pathes and borg output N pathes, it works correctly, including N == 0.

[WilliamDEdwards]

It is a pattern, but when no typical pattern operators are used, I would expect it to be a literal match on the path - behaving as such, thus failing when that path doesn't exist.

Don't get me wrong: I do understand your point, and I don't perceive this to be a bug. Simply a suggestion from a user's perspective.

[ThomasWaldmann]

Somewhere in borg we have a warning (IIRC) if nothing matched.

Could be looked up and compared with this case.
