August 2015 - hibernate-dev - Jboss List Archives

by Gail Badner

Just a gentle reminder that, in keeping with our project's guidelines[1], the 4.2 and 4.3 branches will no longer be actively maintained now that 5.0 has gone Final. I plan to do 1 more 4.3 release (4.3.12) [2]. That will be last 4.3 release. Applications using Hibernate ORM 4.3 should be migrated to use Hibernate ORM 5.0, and bugs reported on 4.3 branch will need to be reproduced on 5.0 branch to be considered for fixing in 5.0 branch.

Query Parser Redesign

by Steve Ebersole

Andrea, this is in relation to something you asked me on IRC today. Specifically in regards to FromClause and the fact that it maintains pointers to parent/children. As I said on IRC there is no intrinsic need (I do not foresee) for keeping this structure; I really only did that because FromCauseProcessor needed a stack of FromClauses and the FromClause itself made a simple place to do that. However, in later work I ran into minor problems because of that decision. I need to make a copy of an entire SelectStatement tree. But because the FromClause is held twice (for non-root FromClauses) in the tree, it makes it more complicated to do a "simple copy" than it need be. Basically I need to maintain a "Map<FromClause,FromClause> copy Map" :( Long story short, I think I might revisit that decision and instead write a dedicated stack in FromClauseProcessor for this. In the morning... its too late to start something that ambitious tonight. I'll start that in the morning, unless someone wants to pick that up in the next few hours before I get back on line.

Testing Hibernate 5: injecting a Spring managed interceptor

by Guillaume Smet

Hi, As I have cycles this week and next week, I thought I might as well do some QA on Hibernate 5. I'm still in the process of porting our code to 5 atm and I have a pattern we used before I can't find an elegant way to port on Hibernate 5: this pattern is used to inject a Spring managed interceptor. We override the persistence provider to inject the interceptor in the Hibernate configuration: https://gist.github.com/gsmet/e8d3003344938b1d327b I studied the new code for quite some time and I couldn't find a way to inject my interceptor in 5. Note that it's a pretty common usage in the Spring managed world. Thanks for any guidance. -- Guillaume

Re: [hibernate-dev] Ansible set-up, error "unknown key type ecdsa"

Ansible set-up, error "unknown key type ecdsa"

by Gunnar Morling

Sanne, When running Ansible to update the CI slaves on OS X, I get the following error: TASK: [jenkins-slave | Ensure cimaster is a known host] *********************** unknown key type ecdsa fatal: [209.132.178.232] => lookup_plugin.pipe(ssh-keyscan -t ecdsa 54.174.65.136) returned 255 Can we use another key type than "ecdsa"? Apparently the SSH coming with OS X has no support for it (see [1]) and I'd prefer to use the default version rather than having to install another one. Thanks, --Gunnar [1] http://apple.stackexchange.com/questions/77731/ecdsa-ssh-key-on-10-8-2

Search/Validator: Deleting old release files on hibernate.org

by Gunnar Morling

Sanne, Hardy, Can we delete all the non-displayed release files from https://github.com/hibernate/hibernate.org/tree/staging/_data/projects for Search and Validator? Fetching them takes a considerable time in the website build and I don't think they are needed any longer once set to display=false and a subsequent release has been done. Thanks, --Gunnar

[HSEARCH] Wrong query results when embedding *-to-many associations

by Gunnar Morling

Hi, in the forum [1] a user runs into a variant of the old problem where boolean searches on different fields of the elements of an embedded association return wrong results due to hits in different elements of the collections. What is our recommendation/answer to this type of question? I've seen it popping up several times, it seems to be a common trap for users. Having an FAQ entry for this would be nice. ES btw. nicely avoids this by storing nested objects in separate "hidden" documents [2]. This allows to run queries without getting results from different collection elements. It'd be a nice addition to do something similar in HSEARCH? Thanks, --Gunnar [1] https://forum.hibernate.org/viewtopic.php?f=9&t=1041259 [2] https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping-n...

SEO ranking of ORM docs

by Gunnar Morling

Hi, When searching the web for things around Hibernate ORM, I often find 3.x documents as the top result. E.g. searching for "hibernate inheritance" on Google returns https://docs.jboss.org/hibernate/orm/3.5/reference/en/html/inheritance.html as the first result. Instead it would be nice to see https://docs.jboss.org/hibernate/orm/4.3/manual/en-US/html/ch10.html there (or some other up-to-date docs containing the relevant information), i.e. docs from the latest stable release. I have no idea really what would have to be done to achieve that. But maybe someone else knows the right knobs to turn? Cheers, --Gunnar
