Don't assume that the @pkgdep lines in a given package on the FreeBSD servers will always point to an existing package. If it doesn't, watch what happens: Latest/foo.tbz based on s/@name (.*)-[^-]+$/$1/ extract foo.tbz entirely, rather then just +CONTENTS which is the first file in the tar archive find out that foo = foo-older-then-installed and discard the package I've solved this myself with an index format like this: # bzcat /var/pkg/7-stable/All/INDEX.bz2 |tail -1 archivers/zip:zip-3.0.tbz:72f4fcc337c74240eaa8ae989a452835231fe7ff32c7469094e3a5fe411d7430:181194 $origin:$pkgname.tbz:$sha256:$size High level view: Compare btree of /var/db/pkg with btree of indexfile, download and upgrade. Saves bogus downloads and doesn't need a portstree. Cons: buildserver needs to periodically create the index, index needs to be downloaded. -- Mel Problem with today's modular software: they start with the modules and never get to the software part. _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
