Until now, these embedded strings were SDS type 8, because they were copied as-is from EMBSTR encoded string objects, which always use SDS type 8. This change allows them to be embedded as SDS type 5, saving two bytes.
The implementation of embeddeding SDS strings in other structures is refactored.
sdswrite()
is a new function to create an SDS representation into a buffer provided by the caller, instead of allocating it.sdscopytobuffer()
which just copied the layout of an existing sds is deleted.The DEBUG SDSLEN command output is changed slightly, to account for correct allocation sizes of embedded strings and not report the same memory twice.
Fixes #1567
