In how far is it complex, actually? File differences is at the core of for example git(1), and i do not mention all the other version control systems since sccs(1) from now i think 50 years (Marc Rochkind posted on Dec 13th IEEE Transactions on Software Engineering has asked me to write a retrospective on the influence of SCCS over the last 50 years, as my SCCS paper was published in 1975. They consider it one of the most influential papers from TSE's first decade. ), i mention git(1) because it now drives a lot of things, like email archives etc. Binary file differences / delta algorithms have a very long tradition. For the BSDiff that bsdipa "is" here https://en.wikipedia.org/wiki/Delta_encoding it seems that Google uses "it" in Chromium and Android, the RPM package manager of RedHat etc. If that isn't "scale", i do not know. (Do not trust the wikipedia however, i have seen all diffs in the FreeBSD source code, and if that is Google, .. i am not surprised.) |already published and uses a very well-established method has been |implemented before seems oddly counter-productive. | |d/ | |p.s. glad to hear you have done some local testing of an unmunger.
