https://bugzilla.redhat.com/show_bug.cgi?id=464854 [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 ou It 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 ou It 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 it to 1. Instead, it was cleared each time the function is called. It let index_range_read stop reading when it reaches sizelimit even though it should not have. [Proposed Fix] Created an attachment (id=328581) --> (https://bugzilla.redhat.com/attachment.cgi?id=328581) cvs diff ldapserver/ldap/servers/slapd/back-ldbm/filterindex.c Fix Description: list_candidates sets SLAPI_SEARCH_IS_AND to 1 in pblock when the filter starts with AND. This function is recursively called and the IS_AND info should be passed to the descendent candidates functions. The IS_AND flag is cleared only by the function which sets it to 1.
