The committer info in every commit will be the same as the author info, so the repository conversion is completely deterministic.
For cvsimport, it is not deterministic. Given cvs' ambiguous/buggy/inconsistent internal semantics around some operations, cvsps makes educated guesses about what happened. Later commits can affect those educated guesses. IIRC, this affects the exact tree at the birth of a branch, and files added on a branch (instead of on HEAD). If you use cvsimport in 'incremental' runs you won't have this problem. Whatever it decided to do, sticks. I haven't worked in detail with Keith Packard's parsecvs but I assume it has similar issues. hth, m -- martin.langhoff@gmail.com martin@laptop.org -- School Server Architect - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff
