Bug#148437: ITP: Tra -- a file-system synchronizer
Package: wnpp
Severity: wishlist
Description:
Tra is a portable user level file system synchronizer designed to
facilitate easy disconnected operation. Most tools like Tra employ
version vectors, while Tra instead uses vector synchronization and
modification times. The semantic difference is small but has
significant effects; in particular, Tra operates without distributed
garbage collection.
Unlike most other synchronization tools, Tra can synchronize replicas
on multiple hosts, even when some of those hosts are temporarily
unavailable. For example, if at some time in the past A and B were
synchronized, and at a different time B and C were synchronized, it
is possible to synchronize A and C. This doesn't work well with
tools like Unison, which do pair-wise synchronization.
However, Tra is still in early development. It doesn't yet have a
GUI interface, the command-line interface is still evolving, there is
no support for Windows hosts, and it has received only limited
testing. Meanwhile, this package is meant to facilitate testing and
development of Tra.
