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.

Bot for checking contribution rules in Hibernate projects
by Yoann Rodiere
Hello everyone,
I just deployed a GitHub bot on our infrastructure. The purpose of this bot
is to run basic checks on pull requests, so that contributors know right
away if something needs to be changed, without having to wait for a human
to take the time to review. And to avoid oversights for some boring, but
nevertheless important rules.
You can see a few failing checks in this playground project:
-
https://github.com/yrodiere/hibernate-github-bot-playground/pull/6/checks
- https://github.com/yrodiere/hibernate-github-bot-playground/pull/6
Pull requests failing these checks can still be merged ; the checks are
only here to help, not to enforce anything. So if you need to merge a few
commits that do not mention a JIRA ticket (e.g. changes in github
workflows), you can still do it.
The checks are obviously very simple. At the moment, we check:
- That the pull request title has at least two words
- That the pull request title doesn't end with a dot or ellipsis (they
are a sign that the title may be incomplete)
- That every commit message starts with a JIRA ticket key.
- That the pull request title/description mentions all JIRA ticket keys
mentioned in commit messages.
We can definitely work on adding more checks, or tuning the existing
checks. Please create issues here:
https://github.com/hibernate/hibernate-github-bot/issues
The bot is currently only enabled on Hibernate Search and Hibernate ORM. If
you want to enable it on other projects, please follow instructions here:
https://github.com/hibernate/hibernate-github-bot/#enabling-the-bot-in-a-...
To anyone interested, the bot was implemented using Quarkus and Guillaume's
GitHub extension: https://github.com/quarkiverse/quarkus-github-app
Cheers,
Yoann Rodière

Dialect.supportsValuesList() ignored for InsertUpdateTests.testInsertValues
by Mark Rotteveel
Testing against Firebird, it seems like Dialect.supportsValuesList() is
ignored.
Specifically the test
org.hibernate.orm.test.query.hql.InsertUpdateTests.testInsertValues
generates the following statement even with Dialect.supportsValuesList()
return false:
```
insert
into
Ticket
(id, ticket_key, subject, details)
values
(2, 'XYZ123', 'Outage', 'Something is broken'), (
13, 'HIJ456', 'x', 'x'
)
```
Or is this a situation where this is ignored because the HQL explicitly
contains two lists?

Query generated for insert ... select
by Mark Rotteveel
For an INSERT ... SELECT, Hibernate (in wip/6.0) will generate a SQL
statement with parentheses around the select statement.
This happens in AbstractSqlAstTranslator.visitQuerySpec(QuerySpec
querySpec) because the querySpec is not a root. Firebird doesn't support
a parenthesized select in insert (yet).
What would be the best way to address this in the AstTranslator or
elsewhere? Overriding the entire visitQuerySpec(QuerySpec querySpec)
method could be brittle as significant changes would need to be
replicated to the Firebird-specific translator, and this only really
applies when processing a select in an insert statement (I think; there
are some other places where Firebird doesn't support parenthesized
selects where the standard does).

List of keywords in AnsiSqlKeywords.java incomplete
by Mark Rotteveel
I was doing some testing Firebird against wip/6.0 and I tripped over the
fact the list of keywords in AnsiSqlKeywords.java (introduced for
https://hibernate.atlassian.net/browse/HHH-9768) is incomplete.
For example, the keyword POSITION is missing from the list, while it is
listed in SQL:2003 <reserved word>, on the other hand ADD is in the
list, which is only listed as non-reserved in <non-reserved word>. I
also notice that most - if not all - other function names are missing.
Firebird is particular finicky about keywords. I see two approaches:
1) I add the difference between the current list in AnsiSqlKeywords +
DatabaseMetaData.getKeywords() (which only returns those not reserved in
SQL:2003) and Firebird's actual keywords explicitly in the dialect
2) I update the list in AnsiSqlKeywords to contain all reserved words
from SQL:2003 (+ retain any additional keywords currently in the list)
This last option would have compatibility consequences (as additional
keywords may get quoted, which could change case-sensitivity for some
databases), so that may not be desirable.
Your thoughts on this?
Mark
