Instead, I > think it "knows" on the server which binary diffs to send down to convert > specific known old versions of files to the current version of each file. For files in MergeChanges, the freebsd-update client will download both versions and then use diff3 to merge changes. For other files, the freebsd-update client will either leave the existing f= ile unchanged (UpdateIfUnmodified files with hashes which don't match the old release) or update to the new version; that updating can optionally use bin= ary diffs but that's just an optimization and if binary diffs don't work then it will fetch the entire new file. --=20 You are receiving this mail because: You are the assignee for the bug.=
