Subject: [PATCH 3/3] config: complain about --local outside of a git repo
Date: Fri, 12 May 2017 23:29:31 -0400 [thread overview]
Message-ID: <20170513032931.uyvhfw6fgju36ovf@sigill.intra.peff.net> (raw)
In-Reply-To: <20170513032414.mfrwabt4hovujde2@sigill.intra.peff.net>
The "--local" option instructs git-config to read or modify
the repository-level config. This doesn't make any sense if
you're not actually in a repository.
Older versions of Git would blindly try to read or write
".git/config". For reading, this would result in a quiet
failure, since there was no config to read (and thus no
matching config value). Writing would generally fail
noisily, since ".git" was unlikely to exist. But since
b1ef400ee (setup_git_env: avoid blind fall-back to ".git",
2016-10-20), we catch this in the call to git_pathdup() and
die with an assertion.
Dying is the right thing to do, but we should catch the
problem early and give a more human-friendly error message.
Note that even without --local, git-config will sometimes
default to using local repository config (e.g., when
writing). These cases are already protected by similar
checks, and covered by a test in t1308.
