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,

Hibernate organization membership on GitHub
by Yoann Rodiere
Hello,
As part of the move to Commonhaus, I'm currently going through our GitHub
setup, and I'm noticing we have a lot of users with extensive (and I mean
*extensive*, sometimes admin or even owner) access to our
organization/repositories, but who are no longer regular contributors.
Additionally, we also have organization members on GitHub who are not
technically Hibernate members: they have never actually contributed to
Hibernate, but are there for technical reasons, for example because they're
coworkers who helped out with some infrastructure issue.
While it's fine in principle, because we trust these people, it's very,
very far from security best practices. Account hacking happens, email
addresses get stolen, and the people using these GitHub accounts might one
day be an attacker instead of the person we trust.
According to Commonhaus' automated report, we're currently at 32 people
having admin rights on one Hibernate repository or another. Which I think
we can all agree is much more than necessary.
For that reason, I'd like to propose that:
1. *We create an "Alumni" team in our GitHub organization*, moving to that
team anyone who is actually a member, but hasn't contributed for... let's
say 2 years? Of course this isn't a permanent thing, and we can simply move
alumni back to the relevant team if they become active again.
2. *We move non-members out of our GitHub organization*, or to "external
collaborators" (that's a GitHub feature) if still necessary.
3. *We schedule yearly audits of our GitHub configuration* to review access
rights again in the future, and move people to the Alumni team as necessary.
Note moving people in and out of teams will get them notified, so I would
send another email directly to impacted people before/during the move, to
avoid this being seen as personal/insulting. It's really not.
*Thoughts, opinions, +1s?*

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.

Boilerplate for LGPL+ASL2 agreement
by Yoann Rodiere
Hello,
Marko did some work on the Hibernate GitHub bot so that certain Hibernate
Team Members can be spared the "I accept both LGPL and ASL2" boilerplate in
their PR description (see [1] for full text).
This does not change requirements, and is only intended for convenience,
for frequent contributors. We are still licensing newer versions of our
projects under ASL2, but we still need agreement with LGPL in order to be
able to backport contributions.
*If you are a Hibernate team member on GitHub*, and want this check to be
skipped, please read the text below, check that you agree, and send that
text back verbatim as a reply to this message.
I confirm that all contribution I will make to Hibernate projects will be
> made under the terms of the Apache 2.0 license (
> https://www.apache.org/licenses/LICENSE-2.0.txt) and can be relicensed
> under the terms of the LGPL v2.1 license (
> https://www.gnu.org/licenses/old-licenses/lgpl-2.1.txt) in the future at
> the maintainers' discretion.
For the record, we keep track of such members by adding them to the
"license-agreement" team in the Hibernate organization.
