The reftable format is usually used with files for storage. However, we abstract away this using the blocksource data structure. This has two advantages: * log blocks are zlib compressed, and handling them is simplified if we can discard byte segments from within the block layer. * for unittests, it is useful to read and write in-memory. The blocksource allows us to abstract the data away from on-disk files. Signed-off-by: Han-Wen Nienhuys <hanwen@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
