Summary
FilePutnow hashes the complete seekable body withio.Copy, so a legal short read cannot leave zero-padded bytes in the SigV4 payload hash. It rewinds the body before sending and avoids allocating a second buffer sized to the entire file. A local HTTP regression test checks both the transmitted body and hash header.Fixes #47.
Verification
go test -run '^TestFilePutHashesCompleteBodyWithShortReads$' ./...— passed.git diff --check— passed.
