Author: Michael Schroeder Date: 2016-10-24 (Mon, 24 Oct 2016) Changed paths: M src/backend/BSSrcdiff.pm Log Message: ----------- [backend] add batcher support to BSSrcdiff.pm If we need to do lots of diffs for a bif tar archive, we call the diff program from an extra process. While this sounds like something that makes no sense at all, it actually speeds up diffing by a factor of 20. The reason is that fork/exec is much slower if the process has a big memory size. A better approach would be a perl module that does the diffing with no exec at all but alas, there seems to be no such thing (execpt a pure perl version that is too slow).
