Hi Here is a patch to resolve FS#18769. I created a new INFRQ/infolevel to describe package download size, so that it could be lazily calculated like most of the other package info. This differs slightly from most of the other infolevels, which correspond to information actually read by _alpm_db_read and alpm_pkg_load. However, I felt it better to do it this way than setting the download size to -1 for invalid, as this would make it the only field in pmpkg_t that needs to be initialized to something other than 0. It is also possible that the download size will be reported incorrectly if a package download size is read, and then that same package is downloaded with alpm_fetch_pkgurl. However, this is better than the present situation where download sizes aren't reported at all, and furthermore this is unlikely since alpm_fetch_pkgurl would probably not be used to download a package that is in the repositories. Thanks for your time, Jonathan
