Subject: Let “ccache --hash-file” perform raw hashing again
X-Git-Tag: v4.0~389
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9875edc2e1de486d2db1131595a7a1a4fc858dce;p=thirdparty%2Fccache.git

Let “ccache --hash-file” perform raw hashing again

Unintended or not, #577 (213d9883) changed the behavior of “ccache
--hash-file” to use hash_binary_file, which essentially performs
hash(hash(path)) if the i-node cache is enabled, otherwise hash(path).
This means that “ccache --hash-file” behaves differently depending on if
i-node cache is enabled and also that it’s no longer usable for
benchmarking purposes.

Fix this by simply using “hash_file” again.
