[Description of Problem]If sizelimit is specified (e.g., -z 5) in ldapsearch, the filter including a range search does not return expected entries even if entries matches the filter.How to reproduce the problem: Create a test ldif file with dbgen.pl $ dbgen.pl -o /path/to/example10k.ldif -n 10000 Import it $ ldif2db -n userRoot -i /path/to/example10k.ldif Start the server $ start-slapd Run the following command $ ldapsearch -D 'cn=Directory Manager' -w <pw> -b "dc=example,dc=com""(&(l=Boston)(|(ou=Payroll)(ou=Accounting))(roomNumber>=9700))" dn roomNumber l ouIt returns 7 entries.$ ldapsearch -D 'cn=Directory Manager' -w <pw> -b "dc=example,dc=com" -z 5 "(&(l=Boston)(|(ou=Payroll)(ou=Accounting))(roomNumber>=9700))" dn roomNumber l ouIt returns no entries. This entry count could be random from 0 to 5. Expected result: returns 5 entries Problem description:SIZELIMIT is checked in index_range_read to eliminate the unnecessary data retrieval. But when the filter contains a range search which is connected by AND, then we should not do sizelimit. There was a bug in the function which sets is_and. The flag should have been cleared only when the function set itto 1. Instead, it was cleared each time the function is called. It letindex_range_read stop reading when it reaches sizelimit even though it shouldnot have.
[Revised proposed fix] Created an attachment (id=328591) --> (https://bugzilla.redhat.com/attachment.cgi?id=328591) Revised: cvs diff ldapserver/ldap/servers/slapd/back-ldbm/filterindex.c Thanks to Nathan for pointing out the flaw in my previous proposal. It had a bug in the nested AND case. Inner AND was clearing "is_and", which should not have. It was fixed in this new proposal.
