Bug 668116 – dev-vcs/git-2.19.1: fatal: unable to start cache daemon: No such file or directory

• Status: UNCONFIRMED
• Product: Gentoo Linux

[Description Dennis Schridde 2018-10-09 08:18:37 UTC]

I was wondering why Git would still ask me for a password, even though I have:
```
# cat .gitconfig 
[credential]
        helper = cache --timeout 86400
```

Reading the source [1] I tried:
```
# /usr/libexec/git-core/git-credential-cache --timeout=86400 store
^D
fatal: cannot run git-credential-cache--daemon: No such file or directory
fatal: unable to start cache daemon: No such file or directory
```

[1]: https://github.com/git/git/blob/master/credential-cache.c

Next I straced the process:
```
# strace /usr/libexec/git-core/git-credential-cache --timeout=86400 store
^D

```

On Gentoo the binary is located here:
```
# q list -e git | grep git-credential-cache--daemon
/usr/libexec/git-core/git-credential-cache--daemon
```

It seems that either the binary should be in the default `PATH` or Git should be fixed to also search in `/usr/libexec/git-core`.
