config value 'safe.directory' was not found

[ernstki]

Probably everybody else has already dealt with this, but I work in an environment which lags behind the latest releases of things like Git by quite a ways.

Building git-hist 1.0.5 with cargo and Rust 1.71 is successful, but I receive this error message upon actually running git hist FILENAME:

$ git-hist FILENAME
Error: Faild to open a git repository for the current directory

Caused by:
    config value 'safe.directory' was not found; class=Config (7); code=NotFound (-3)

I believe this relates to a recently-discovered security vulnerability in Git, and a resulting workaround in git2-rs. I'll update the issue description with references as I do more research.

As a temporary workaround, you can define GIT_CEILING_DIRECTORIES as described here. Edit: git2-rs really wants what it says it wants, which is to see safe.directory for the current directory in ~/.gitconfig. Here's how to add that:

$ git config --add --global safe.directory $PWD

• update libgit2 to newer snapshot rust-lang/git2-rs#839

Note this is an upstream Git, libgit, and git2-rs problem, not git-hists's problem, therefore closing.

I just wanted to document it here for posterity, in case this error message from git-hist was someone else's first encounter with it.
