Subject: A loose object is not corrupt if it cannot be read due to EMFILE
X-Git-Tag: v1.7.4-rc0~92^2~2
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=3ba7a065527a;hp=b6c4ceccb3d6026c612fa55865c51374b26eb176;p=git.git

A loose object is not corrupt if it cannot be read due to EMFILE

"git fsck" bails out with a claim that a loose object that cannot be
read but exists on the filesystem to be corrupt, which is wrong when
read_object() failed due to e.g. EMFILE.
