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.

Still an issue with Agroal when closing the pool
by Guillaume Smet
Hi Luis,
We talked at some point about a potential issue in Agroal, you said 1.3
should have all the known issues solved but apparently, there is still one
as we have transient test failures on ORM from time to time.
A good example is the following one:
http://ci.hibernate.org/view/ORM/job/hibernate-orm-master-h2-javassist/la...
(it's build #265, haven't found a way to get a stable URL from Jenkins)
The issue is in this test:
org.hibernate.test.agroal.AgroalTransactionIsolationConfigTest.testSettingIsolationAsName
.
And we have the following stacktrace when closing the pool:
java.util.concurrent.RejectedExecutionException: Task
java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask@189a0b8e
rejected from io.agroal.pool.util.PriorityScheduledExecutor@2ded5d2e[Shutting

at org.hibernate.testing.common.connections.BaseTransactionIsolationConfigTest.testSettingIsolationAsName(BaseTransactionIsolationConfigTest.java:101)
It happens once in a while. I already had the issue locally but lately I
only observed it on CI.
I suppose it won't be easy to get to the bottom of it but it would be nice
if we could get this fixed.
Thanks.

Chat migration - D minus 115 until the death of HipChat
by Yoann Rodiere
Hi,
TL;DR: please vote here if you don't want to end up having to use a chat
tool you don't like: https://doodle.com/poll/h6scc9bsh6a4ymre
HipChat Cloud will stop working on February 15th, 2019 [1]. We need to
choose an alternative before we have our back against the wall, so I'll try
to resurrect the conversation.
As a reminder, Stride is no longer an option: Atlassian cancelled the
project, and encourages users to migrate to Slack.
The discussed options so far were:
- *Moving back to IRC*. Aye: ?; nay: ?
Pros: simple as hell.
Cons: basic as hell; we won't keep the chat history.
- *Migrating to Slack* [6], as suggested by Atlassian [2]. Aye:
Christian B; Nay: ?
Pros: we will keep the chat history (I think).
Cons: not open-source; desktop client consumes a lot of resources.
- *Migrating to Zulip* [3]. Aye: Emmanuel, Yoann. Nay: Guillaume (kind
of).
Pros: Advanced conversation management thanks to the "topics" feature.
Cons: Complex to use because of the "topics" feature; we won't keep the
chat history (1).
- *Migrating to Gitter* [5] (we'll create different rooms, probably).
Aye: ?, Nay: ?
Pros: Users seem to actually go there, so we could have our "live
support" rooms next to our "internal discussion" rooms.
Cons: not open-source; we won't keep the chat history (1).
I created a poll based on the discussion we had on the thread
"[hibernate-dev] Stride". I think everyone had the time to suggest another
option.
Please vote here and now, or remain silent forever ;):
https://doodle.com/poll/h6scc9bsh6a4ymre
I'd suggest the following rules: if there's a single clear winner (a
platform that everyone would be happy with), we'll pick that one. If there
are multiple clear winners, whoever does the migration work will pick
what's easier to set up (taking into account the various integrations).
Otherwise, back to discussing it on this thread...
(1) There seems to be some work in progress on a migration tool from
HipChat to Zulip, but it doesn't seem to be ready yet [4]

Loggers
by Steve Ebersole
Yes, I know no one likes talking about logging. "Its not important", until
it is ;)
TLDR I am considering moving to using "module names" for logger names
instead of Class names even for DEBUG/TRACE logging and see if anyone had
strong arguments to not do this..
Full version---
For some time I have been moving to an approach of defining message
loggers[1] using a single contract per function or "module" - e.g.:
1. the second level caching module uses the dedicated message logger
`ConnectionPoolingLogger`
2. the ManagedBeanRegistry module uses the dedicated message logger
`BeansMessageLogger`
3. etc
Each of these define a dedicate instance instance they can use. E.g.
ConnectionPoolingLogger is defined as:
````
@MessageLogger( projectCode = "HHH" )
@ValidIdRange( min = 10001001, max = 10001500 )
public interface ConnectionPoolingLogger extends BasicLogger {
ConnectionPoolingLogger CONNECTIONS_LOGGER = Logger.getMessageLogger(
ConnectionPoolingLogger.class,
"org.hibernate.orm.connections.pooling"
);
...
}
````
I won't get into all the whys I do this unless someone cares ;)
But I am contemplating doing the same for basic loggers so I wanted to ask
everyone else's opinion since this means a change in how you'd have to
configure logging for DEBUG/TRACE output. Usually you'd use the Class name
as the logger name and use that to control logging in the back-end (log4j,
etc). If I do this, you'd have to instead use the module name.
There are quite a few reasons I am considering this, including all of the
reasons I did it for message loggers in the first place. If I am
debugging the loading of a collection or an entity, today I'd have to know
all the packages involved (there is no common root name) and list them in
my log4j.properties; that is because the process is ultimately handled by
delegates or helpers in many different packages (`org.hibernate.loader`,
`org.hibernate.persister`, `org.hibernate.type`, ...). It sure would be
nice to just be able to say `org.hibernate.loading` or
`org.hibernate.loading.entity` or `org.hibernate.loading.collection` or ...
for a number of reasons:
1. When we need to see logging from someone it is a lot easier to tell
the module name(s) you need enabled as opposed a list of package and class
names.
2. When running JPA TCK it is essentially impossible to attach debugger
to step through code when debugging a failure - you have to rely on
debugging through output. *Well that used to be the case, but the
latest TCK broke logging to STDOUT somehow so we ended up having to try and
reproduce the failure in our testsuite - so then it does not matter either
way ;)*
3. Easier to document -
http://docs.jboss.org/hibernate/orm/5.3/topical/html_single/logging/Loggi...
Thoughts?
[1] JBoss Logging's `org.jboss.logging.annotations.MessageLogger` - which
we use for user-focused log messages. Should always be logged at >= INFO
[2]
[3] JBoss Logging's `org.jboss.logging.BasicLogger` - which we use for
developer-focused log messages (for debugging). Should always be logged at
DEBUG or TRACE
