Bug description:
Hi,
I've just performed an upgrade of our LDAP server on Ubuntu 10.04.4
LTS to Ubuntu 12.04 (I acknowledge this upgrade path is not officially
supported yet).
The incompatible database upgrading process in the preinst/postinst
files failed in the following scenario.
We have two suffixes/databases at the following paths:-
* /var/lib/ldap
* /var/lib/ldap/accesslog
The preinst database dumping part of the process worked just fine and
created the appropriate LDIF files under
/var/backup/slapd-2.4.21-0ubuntu5.7, however the restore failed
stating:-
"""
Loading from /var/backups/slapd-2.4.21-0ubuntu5.7:
- directory dc=REDACTEDs,dc=co,dc=uk... failed.
Loading the database from the LDIF dump failed with the following
error while running slapadd:
4fbdfebf olcDbDirectory: value #0: invalid path: No such file or directory
4fbdfebf config error processing olcDatabase={2}hdb,cn=config:
olcDbDirectory: value #0: invalid path: No such file or directory
slapadd: bad configuration directory!
"""
This is because when move_incompatible_databases_away() runs it finds
the main database first (/var/lib/ldap) and moves all top level
entries (find -mindepth 1 -maxdepth 1 ...) into the backup directory
and this includes the accesslog subdirectory which then no longer
exists. When slapadd runs it checks config specifying that directory
and bails with the above error given it is indeed missing.
I've tested a tentative fix and that's to patch the two find commands
(one in is_empty_dir() one in move_old_database_away to also specify
-type f so that the directory structure is preserved when moving the
old database away (accesslog will be backed up separately when its
suffx is iterated over in move_incompatible_databases_away()).
The simple and very tentative patch for this is:-
