NAME<\/a> applydeltarpm \u2212 reconstruct an rpm from a deltarpm<\/p>\n applydeltarpm<\/b> [-v<\/b>] [-p<\/b>] [-r<\/b> oldrpm<\/i>] deltarpm newrpm<\/i> applydeltarpm applies a binary delta to either an old rpm or to on-disk data to re-create a new rpm. The old rpm can be specified with the -r<\/b> option, if no rpm name is provided on-disk data is used. You can use -p<\/b> to make applydeltarpm print the percentage of completion, or -v<\/b> to make it more verbose about its operation.<\/p>\n The second an third form can be used to check if the reconstruction is possible. It may fail if the on-disk data got changed (deltarpms are created in a way that config file changes do not matter) or the deltarpm does not match the rpm the delta was generated with. The -c<\/b> option selects full (i.e. slow) on-disk checking, whereas -C<\/b> only checks if the filesizes have not changed.<\/p>\n Instead of a full deltarpm a sequence id can be given with the -s<\/b> sequence<\/i> option. Such an id contains all the information that is needed to do reconstruction checking.<\/p>\n Finally information about a deltarpm can be printed with the -i<\/b> option.<\/p>\n applydeltarpm was written to work on systems with limited memory. It uses a paging algorithm to keep the size of in-core data low and not bring the system in an out-of-memory situation.<\/p>\n applydeltarpm returns 0 if the rpm could be recreated or the checking succeeded, it returns 1 and prints an error message to stderr if something failed.<\/p>\n
