[JIRA] (HHH-16155) Problem with @Generated and jdbc.batch_size

by Danilov Roman (JIRA)

Danilov Roman ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=70121%3... ) *created* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiYzc5YmFhNTQz... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-16155?atlOrigin=eyJpIjoiYzc5Ym... ) HHH-16155 ( https://hibernate.atlassian.net/browse/HHH-16155?atlOrigin=eyJpIjoiYzc5Ym... ) Problem with @Generated and jdbc.batch_size ( https://hibernate.atlassian.net/browse/HHH-16155?atlOrigin=eyJpIjoiYzc5Ym... ) Issue Type: Bug Affects Versions: 6.1.6, 6.1.7 Assignee: Unassigned Attachments: hibernate-orm-6.zip Components: hibernate-core Created: 09/Feb/2023 03:58 AM Priority: Major Reporter: Danilov Roman ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=70121%3... ) After updating hibernate version from 5.6.12 to 6.1.6, a problem appeared. If Entity has field with annotation @Generated () and hibernate’s properties have parameter jdbc.batch_size > 0 then when new object of entity is saved to the database, an error appears in the logs and the saving does not occur. The error occurs in the class org.hibernate.metamodel.mapping.internal.GeneratedValuesProcessor. And the problem is that when in entity there is an annotation @Generated over the field, then in hibernate, first, it is saved in the database, and then these generated fields are received from the database. And apparently, when there is jdbc.batch_size > 0 setting, then INSERT to the database does not occur immediately, and SELECT tries to find a line in the database that is not there yet. With the old version of hibernate 5.6.12 everything worked without errors. Link to https://discourse.hibernate.org/t/problem-with-generated-and-jdbc-batch-s... ( https://discourse.hibernate.org/t/problem-with-generated-and-jdbc-batch-s... ) with more info. And i have attached test cases.

[JIRA] (HHH-13664) SimpleTimestamper hangs in loop when system clock jumps backwards

by Sanne Grinovero (JIRA)

Sanne Grinovero ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *commented* on HHH-13664 ( https://hibernate.atlassian.net/browse/HHH-13664?atlOrigin=eyJpIjoiMTJjOT... ) Re: SimpleTimestamper hangs in loop when system clock jumps backwards ( https://hibernate.atlassian.net/browse/HHH-13664?atlOrigin=eyJpIjoiMTJjOT... ) Hi Irina, I would suggest reading or listening some of the works of Stephen Colebourne about this topic; I just found this summary: https://www.infoq.com/articles/java.time ( https://www.infoq.com/articles/java.time ) - in particular read the section about Timezones. > > > > But the key fact is that time-zones are political creations. They are > often used to demonstrate political control over an area, such as the > recent change in Crimea to Moscow time. As with anything political, the > associated rules frequently defy logic. The rules can and do change with > very little notice. > > Clearly, that should be enough motivation for us engineers to not rely on such a time reference; especially not for timestamped coordination or for any situation in which a timestamp is required to disambiguate different instants in the “continuous flow of time” which we rely on in our models of reality (ignoring more advanced physics for sake of practical applications). I do wonder if we could do something better in Hibernate, but a the moment I can’t produce a better suggestion than to use UCT with NTP on any servers.

[JIRA] (HHH-13664) SimpleTimestamper hangs in loop when system clock jumps backwards

by Irina Tarasenko (JIRA)

You said “Of course never run a server in local timezones.” Could you explain a bit more?

[JIRA] (HHH-16154) Hibernate envers and ElementCollection

by Pierre-Alexandre Mancaux (JIRA)

Pierre-Alexandre Mancaux ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=5ccadf3... ) *created* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiNjVmNTAyZTg4... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-16154?atlOrigin=eyJpIjoiNjVmNT... ) HHH-16154 ( https://hibernate.atlassian.net/browse/HHH-16154?atlOrigin=eyJpIjoiNjVmNT... ) Hibernate envers and ElementCollection ( https://hibernate.atlassian.net/browse/HHH-16154?atlOrigin=eyJpIjoiNjVmNT... ) Issue Type: Bug Affects Versions: 5.6.14 Assignee: Chris Cranford ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) Components: hibernate-envers Created: 09/Feb/2023 00:21 AM Priority: Major Reporter: Pierre-Alexandre Mancaux ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=5ccadf3... ) I have a simple program with a Resource and List of ItemSelection like this @Audited @Table(name = "resource_item") public class Resource { @Id @GeneratedValue(strategy = GenerationType.AUTO) @Access(AccessType.PROPERTY) private Long id; private String nom; @ElementCollection(targetClass = ItemSelection.class) @CollectionTable(name = "item_selection", joinColumns = @JoinColumn(name = "resource_id")) @OrderColumn(name = "list_order") private final List<ItemSelection> itemSelections = new ArrayList<>(); ... ... @Embeddable @Access(AccessType.FIELD) public class ItemSelection { //@Column(name = "hierarchy_code", nullable = false) private String hierarchyCode; //@Column(name = "hierarchy_level", nullable = false) private int hierarchyLevel; //@Column(name = "hierarchy_value_code", nullable = false) private String hierarchyValueCode; ... ... When i m adding resource with 3 elements in itemSelections, hibernate envers log correctly: localhost sa@envers=# select * from item_selection_aud ; rev | revtype | resource_id | list_order | hierarchy_value_code | hierarchy_code | hierarchy_level -----+---------+-------------+------------+----------------------+----------------+----------------- 2 | 0 | 1 | 1 | hvalueCode3 | hcode3 | 3 2 | 0 | 1 | 0 | hvalueCode1 | hcode1 | 1 2 | 0 | 1 | 2 | hvalueCode2 | hcode2 | 2 (3 rows) when i m updating one line in item_selection, i only see one update in sql but hibernate envers log this: localhost sa@envers=# select * from item_selection_aud ; rev | revtype | resource_id | list_order | hierarchy_value_code | hierarchy_code | hierarchy_level -----+---------+-------------+------------+----------------------+----------------+----------------- 2 | 0 | 1 | 1 | hvalueCode3 | hcode3 | 3 2 | 0 | 1 | 0 | hvalueCode1 | hcode1 | 1 2 | 0 | 1 | 2 | hvalueCode2 | hcode2 | 2 3 | 0 | 1 | 0 | hvalueCode1 | CODE | 1 3 | 2 | 1 | 0 | hvalueCode1 | hcode1 | 1 (5 rows) as you can see, i have a revtype 2 and 0 for the modified line instead of revtype 1 for an update. I'have try to use @Column(name = "hierarchy_code", nullable = false) but nothing change. For now my only solution is to transform @ElementCollection into @OneToMany, but I have many @ElementCollection in my application so too many refactoring... Did I miss something in the configuration? I am using DefaultAuditStrategy, same behavior with ValidityAuditStrategy that only add revend column.
