Th RPM conversion process to new rpm using internal BDB 4.5 (there were too
many problems with BDB 4.6). Conversion is needed because BDB 4.5 cannot read
BDB "Hash version 9" format used in BDB 4.6.
BDB 4.5 is able to read "Hash version 8" and "Btree version 9". Our goal is to
convert databases to "Btree version 9" format, upgrade to new rpm, rebuild
databases once again and finally live with Hash 8 and/or Btree 9 but NOT Hash 9.
What to do:
* create backup of /var/lib/rpm directory
* install db4.6-utils (so you will have recovery tools when something goes
wrong)
* edit /usr/lib/rpm/macross and replace _dbi_config_XYZ {{{_dbi_htconfig}}}
ocurrences with {{{_dbi_btconfig}}} one. It will look like this:
{{{
%_dbi_config_Dirnames %{_dbi_btconfig}
%_dbi_config_Requireversion %{_dbi_btconfig}
%_dbi_config_Provideversion %{_dbi_btconfig}
%_dbi_config_Installtid %{_dbi_btconfig}
%_dbi_config_Removetid %{_dbi_btconfig}
%_dbi_config_Basenames %{_dbi_btconfig}
%_dbi_config_Conflictname %{_dbi_btconfig}
%_dbi_config_Filedigests %{_dbi_btconfig}
%_dbi_config_Group %{_dbi_btconfig}
%_dbi_config_Name %{_dbi_btconfig}
%_dbi_config_Packagecolor %{_dbi_btconfig}
%_dbi_config_Providename %{_dbi_btconfig}
%_dbi_config_Pubkeys %{_dbi_btconfig}
%_dbi_config_Requirename %{_dbi_btconfig}
%_dbi_config_Sha1header %{_dbi_btconfig}
%_dbi_config_Sigmd5 %{_dbi_btconfig}
%_dbi_config_Triggername %{_dbi_btconfig}
}}}
* delete almost all files in /var/lib/rpm/ leaving only file named
"Packages" (s at the end!)
* run {{{rpm --rebuilddb}}}. You should now see new database files in
/var/lib/rpm/.
* check with {{{file /var/lib/rpm/*}}} if new databases are one of these:
1. Berkeley DB (Hash, version 8, native byte-order)
2. Berkeley DB (Btree, version 9, native byte-order)
* if you still have "Berkeley DB (Hash, version 9, native byte-order)" then
there is a problem. Consult with [http://lists.pld-linux.org/ PLD mailing list]
subscribers
* upgrade rpm package to latest available
* run {{{rpm --rebuilddb}}} again to get Hash 8/Btree 9 type of databases
