Subject: [PATCH v4 05/13] attr: fix BUG() when parsing attrs outside of repo
Date: Tue, 7 May 2024 06:53:05 +0200 [thread overview]
Message-ID: <f098ce9690f03bd42411b47c4cea23ecc8d96dee.1715057362.git.ps@pks.im> (raw)
In-Reply-To: <cover.1715057362.git.ps@pks.im>
[-- Attachment #1: Type: text/plain, Size: 2167 bytes --]
If either the `--attr-source` option or the `GIT_ATTR_SOURCE` envvar are
set, then `compute_default_attr_source()` will try to look up the value
as a treeish. It is possible to hit that function while outside of a Git
repository though, for example when using `git grep --no-index`. In that
case, Git will hit a bug because we try to look up the main ref store
outside of a repository.
Handle the case gracefully and detect when we try to look up an attr
source without a repository.
