From: Eric W. Biederman Date: Mon, 2 Oct 2023 02:40:29 +0000 (-0500) Subject: object-file: handle compat objects in check_object_signature X-Git-Tag: v2.45.0-rc0~75^2~5 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=8d691757b8fcbe9b7898a5d1dcb37b198a8c60e1;p=thirdparty%2Fgit.git object-file: handle compat objects in check_object_signature Update check_object_signature to find the hash algorithm the exising signature uses, and to use the same hash algorithm when recomputing it to check the signature is valid. This will be useful when teaching git ls-tree to display objects encoded with the compat hash algorithm. Signed-off-by: "Eric W.
