API differences in Hibernate ORM 5.1 vs 5.3
by Gail Badner
Hi,
There were lots of differences in the compatibility report, so as a first
step, I've excluded packages/classes that I considered SPI, internal, or
"grey area". This reduced the the differences to a more manageable amount.
You can see a summary of the incompatibilities along with suggested
mitigation at [1].
The report is attached to [1], along with a zip with instructions for
running the report.
I believe there are some "false positives" in the report, and I have
documented them in the section, "False Positives?".
Feel free to comment on the article.
Thanks,
Gail

IP banned from forum
by Gunnar Morling
Hi,
Is anyone banning users from the forum? I am getting "A ban has been
issued on your IP address."
I don't think banning by IP is a good strategy as many users will have
dynamic IPs from their hoster's shared pool, so it's a random game to
hit an IP previously banned due to some other user's spam.
Thanks,

New CI machine preview
by Sanne Grinovero
You're all welcome to play with http://54.225.162.168/
however please keep these in mind:
- it's not the final machine: don't put too much effort in creating
nice build scripts as we'll reset it to clean state soon. We *might*
be able to store jobs defined so far, but we might choose not to.
- domain name should be coming: ci.hibernate.org ..not sure when, got
no replies so far from.
- authentication: just click on login, it will use OAuth2 to request
your identity via your GitHub account. Permissions to create new jobs,
edit existing jobs, run a build manually depend on your github account
be part of the Hibernate organization (or not, in which case you have
read only status)
At this stage I'd like to get a feeling if the hardware is powerful
enough, and also we need to select which other plugins we want to use,
I'm looking especially to:
- static analysis reports
- pull requests integration
both are relatively undefined, we can of course start simple and
improve later.. just checking this fits basic needs now.

Hibernate ORM: creating branch 5.5, long live 5.6
by Sanne Grinovero
Hi all,
While the Hibernate ORM core experts are focused on Hibernate ORM 6, we
have a small team working on Hibernate Reactive that needs some more
changes done on Hibernate ORM v5.x (as that's what they are using
currently).
I'm keen to apply these and they look great, but honestly I've been
hesitant as they are significant and with larger patches there always is
some degree of risk, no matter how cautious we are.
To better address these needs, I will bump the minor version of releases
more regularly than what we've seen in the past; this doesn't reflect a
change of pace of the project, nor should you expect significant features
to be highlighted in each minor release: it just puts us in a position to
more reliably be able to ship important fixes in older releases, w/o such
release having to include also the many fast paced changes required by the
Reactive team.
I'm confident this makes sense to all: after all that's what the
minor/micro differences are for.
So nothing is really different here, expect that you'll likely see minor
releases happening more frequently from now on.
Thanks,
Sanne

Re: HHH-14736 review and feedback requested

Subject: HHH-14736 advice needed - metamodel updates by Dialect
I am new to the meta model internals of Hibernate, please bear with me.
I am working in processElementAnnotations to use the new VersionColumnSupport to add Dialect based defaults to the meta model – but I seem to be looking at this wrong.
Is there a test case, commit, or other documentation I can review to review as an example?
Basically, if the Dialect says so (e.g. SQL Server @Version on Long) and the author of the Entity does not specify conflicting configuration
Add to the meta model:
@Source(value = SourceType.DBLONG)
@ColumnTransformer(read = "CAST(… as BIGINT)")
@Column(columnDefinition = "rowversion", nullable = false, insertable = false, updatable = false)
@Generated(GenerationTime.ALWAYS)
I was updating the Column in the SimpleValue, but that did not get reflected in the runtime behavior – it only helped with schema generation.
