[JBoss JIRA] (ISPN-5561) Problem in dealing with the HQL queries that contain string comparison operations, when it involves empty string as an operand

by RH Bugzilla Integration (JIRA)

[ https://issues.jboss.org/browse/ISPN-5561?page=com.atlassian.jira.plugin.... ] RH Bugzilla Integration commented on ISPN-5561: ----------------------------------------------- Dave Stahl <dstahl(a)redhat.com> changed the Status of [bug 1238866|https://bugzilla.redhat.com/show_bug.cgi?id=1238866] from POST to MODIFIED > Problem in dealing with the HQL queries that contain string comparison operations, when it involves empty string as an operand > ------------------------------------------------------------------------------------------------------------------------------ > > Key: ISPN-5561 > URL: https://issues.jboss.org/browse/ISPN-5561 > Project: Infinispan > Issue Type: Bug > Components: Embedded Querying, Remote Querying > Affects Versions: 7.2.0.Final > Environment: Infinispan version: Infinispan 7.2.0-Final > Operating System: Linux > Compatibility mode is enabled. > Indexing is enabled and 'autoconfig' parameter is set to true. > Reporter: Pavan Kundgol > Assignee: Adrian Nistor > Fix For: 8.0.0.Beta2, 7.2.4.Final, 8.0.0.Final > > > When a HQL query that involves string comparison operation with the empty string matching is executed through hot rod client(java), it is resulting in the following error, > org.infinispan.client.hotrod.exceptions.HotRodClientException:Request for message id[7] returned server error (status=0x85): org.hibernate.search.exception.EmptyQueryException: HSEARCH000146: The query string '' applied on field 'CITY' has no meaningful tokens to be matched. Validate the query input against the Analyzer applied on this field. > The same problem may also occur when the string matching operation involves a string containing certain special keywords(hibernate search stop words), as operands. > The problem seems to be assosiated with the the 'hibernate-hql-lucene' parser used by the 'infinispan-remote-query-server' module. The problem here is that the hibernate-hql-lucene parser is translating comparison operations directly into lucene keyword matching operations, irrespective of the field type, though the phrase matching is more appropriate for string fields. This leads to invalid query formation when the field in concern is of type string, and is matched against an empty string(or a string containing one or more hibernate search stop words). > For example, > the where condition city='' present in the following HQL query > select name from com.test.User where city='' > is tralated to lucene query, the hql-lucene parser is currently translating to > queryBuilder.keyword().onField("city").matching("").createQuery() > whereas recommended one is > queryBuilder.phrase().onField("city").sentence("").createQuery() > In the former way of translation, Hibernate Search query execution fails due to its usage of standard analyzer while executing the query. Hence, the problem can also be avoided by disabling the standard analyzer while executing the query. > queryBuilder.keyword().onField("city").ignoreAnalyzer().matching("").createQuery() > Preferred solution may be to enhance the 'hibernate-hql-lucene' library to do type specific translations, and to specifically translate the string comparison operations of hql query into phrase matching operations of lucene query(instead of keyword matching operations). -- This message was sent by Atlassian JIRA (v6.3.15#6346)

[JBoss JIRA] (ISPN-5642) Reduce contention in the RPC timeout handling

by Dan Berindei (JIRA)

Dan Berindei created ISPN-5642: ---------------------------------- Summary: Reduce contention in the RPC timeout handling Key: ISPN-5642 URL: https://issues.jboss.org/browse/ISPN-5642 Project: Infinispan Issue Type: Task Components: Core Affects Versions: 8.0.0.Beta2 Reporter: Dan Berindei Priority: Minor Fix For: 8.0.0.Final Most of the RPC timeout tasks are cancelled way before their timeout expires. This means the scheduler spends a lot of time reordering the elements of its DelayQueue. It should be possible to store the tasks with a long timeout (e.g. 1s) in a queue and only move them to the scheduler's priority queue when they have less than 1s to expiration (e.g. by a worker thread that runs every 0.5s) Storing all the tasks in a single queue may be impractical because the worker thread would have more and work to do as load increases and the RPCs take longer to finish, so a [hashed timing wheel|http://www.cse.wustl.edu/~cdgill/courses/cs6874/TimingWheels.ppt] may be needed. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
