Interleaved deltas, or SCCS weave is a method used by the Source Code Control System to store all revisions of a file. All lines from all revisions are "woven" together in a single block of data, with interspersed control instructions indicating which lines are included in which revisions of the file. Interleaved deltas are traditionally implemented with line oriented text files in mind, although nothing prevents the method from being applied to binary files as well.
Interleaved deltas were first implemented by Marc Rochkind in the SCCS in 1975. Its design makes all versions available at the same time, so that it takes the same time to retrieve any revision. It also contains sufficient information to identify the author of each line (blaming) in one block.[1] On the other hand, because all revisions for a file are parsed, every operation grows slower as more revisions are added. The term interleaved delta was coined later in 1982 by Walter F. Tichy, author of the Revision Control System, which compares the SCCS weave to his new reverse delta mechanism in RCS.[2]
