Subject: [PATCH 3/5] match-trees: use hashcpy to splice trees
Date: Thu, 10 Jan 2019 04:25:49 +0000 [thread overview]
Message-ID: <20190110042551.915769-4-sandals@crustytoothpaste.net> (raw)
In-Reply-To: <20190110042551.915769-1-sandals@crustytoothpaste.net>
When we're splicing trees, we're writing directly from one location into
a buffer that is exactly the same size as a tree object. If the current
hash algorithm is SHA-1, we may not have a full 32 (GIT_MAX_RAWSZ) bytes
available to write, nor would we want to write that many bytes even if
we did. In a future commit, we'll split out hashcpy to respect
the_hash_algo while oidcpy uses GIT_MAX_RAWSZ, so convert the oidcpy to
a hashcpy so we copy the right number of bytes.
