Package: pristine-tar Version: 1.33 Severity: normal Hi,
pristine-tar gendelta tarball.tar.gz delta1 pristine-tar gendelta tarball.tar.gz delta2 produces two different deltas, mainly due to different timestamps. It would be great, if pristine-tar could take this into account and create more easily reproducible deltas. One would be to use gzip -n to omit the timestamp when compressing the delta data. Another problem are the timestamps inside the (delta) tarball. The input tarball should have enough sources to provide a usable timestamp: * the gzip timestamp (unless created with gzip -n) * the modification time of the newest file/directory inside the tarball (the filesystem timestamp of that tarball is not a usable option) With a recent tar, there is a --mtime option that could be used while creating the delta tarball. Andreas PS: hmm, using pristine-tar again on the delta it created ... no I'm not going to explore this idea :-)
