Re: (ITS#6500) get_ldap_property returns stale data from time to time

Not clear why you think this is an OpenLDAP bug. There's too little information to determine whether your application is using OpenLDAP's client library correctly.

Hi,

In a high load apache environment I am performing some ldap searches for some requests using a custom developed application and the OpenLdap client libraries.

...

From time to time I have the following segmentation fault:

Program terminated with signal 11, Segmentation fault. #0 0x00000000004033b9 in get_ldap_property (ldap=0x764870, entry=0x841160, attribute=0x87aa50 "smIMEI", context=0x76fc38) at ldap_query.c:30 30 if ( v != NULL && v[0] != NULL ) { (gdb) backtrace #0 0x00000000004033b9 in get_ldap_property (ldap=0x764870, entry=0x841160, attribute=0x87aa50 "smIMEI", context=0x76fc38) at ldap_query.c:30 #1 0x00000000004040f7 in query (pool=0x76fc38, ep=0x610290, ldap_request=0x76ff60) at ldap_query.c:353

And the function is :

char * get_ldap_property(LDAP* ldap, LDAPMessage *entry, char* attribute, apr_pool_t* context) {

char ** v = ldap_get_values(ldap, entry, attribute);

if ( v != NULL && v[0] != NULL ) {
    char* ret = apr_pstrdup(context,  v[0] );
    ldap_value_free( v );
    return ret;
}

return NULL;

}

Note that most of the queries (99%) work fine.

Did anyone experienced something simmilar?

Thanks, Alin
