A friend and me are both working on tools for automated package updates. We intended to rely on the INDEX file to be found on the package repositories, however we came to recognize that the data provided is not reliable. Here's an example: ftp://ftp.de.freebsd.org/pub/FreeBSD/ports/amd64/packages-7-stable/INDEX Yesterday the OOo-3 version listed was openoffice.org-3.0.0 However under ftp://ftp.de.freebsd.org/pub/FreeBSD/ports/amd64/packages-7-stable/All you already found openoffice.org-3.0.0_1 editors/openoffice.org-3.0.0.tbz was a broken link at that time. Today this has returned to a consistent state, however yesterday relying on INDEX would have been fatal. Our code would have attempted to update with the wrong version and gracelessly failed. Was this some kind of exception or do we have to add server/INDEX consistency tests to our algorithms? Shouldn't old packages be kept until they are no longer referenced by the INDEX?
