Announcement: Aim to remove libdb-java from Fedora-rawhide

[Ondrej Dubaj]

Hello everyone,

we are aiming to remove libdb-java package from Fedora-rawhide, as we are
currently preparing for jdk update from jdk-1.8 to jdk-11 in Fedora
rawhide. The problem is that we are unable to rebuild this package with
jdk-11. It is still possible to "hack" it and rebuild it with jdk-1.8, but
that can cause unexpected runtime behaviour according to JVM-11, which will
soon be default in Fedora-rawhide.

There seems to be no packages, which depend directly to libdb-java and
upstream does not support version 5.3.28 anymore.

If anyone has any reasons why this should not be made, or someone is
currently active user of this JDBC connector, please leave a comment with
your opinion in the tracker [1] mentioned below.

There is also an existing tracker for deprecating libdb in Fedora [2], so
this can be understand as a first step.

Additional info about jdk-11 here [3].

Out of curiosity, what is the exact problem?

Thanks,

The problem is unknown runtime behaviour of libdb-java (build with jdk-1.8,
as it is unable to build with jdk-11) with JVM-11. Are you an active user
of libdb java ?

Thanks,
Ondrej

I am not.

Upon second thought, it doesn't seem to make sense to preserve
libdb-java (although I expect that it's only necessary to fix the
autoconf check).

 Maybe. However upstream of is dead. And usptream confirmed that they are unable to verify
that it
works in JDK11.

Imho droppoing such possibly instbale package is probably good way.  If it will be missed,
then it
can be returned, and the one wishing its return will be used as tester.

Is there some replacemnt for this subpackage? At least theoretical?

Agree,

I am not aware of any replacement of this JDBC connector. As you said, it
can be easily returned if it would be missed.

For the JDBC connector to SQLite, there's sqlite-jdbc and javasqlite.
But the on-disk format will be different.

For the key-value store, there is the je package, but again the on-disk
format is different.

Thanks,
Florian

I don;t think this is a reason not removing libdb-java subpackage from
Fedora-Rawhide. If you are an active user of it, or you know somebody who
actively uses it, we can discuss more about these issues.

Thanks,
Ondrej

Hello everyone,

today I am removing libdb-java subpackage from Fedora-rawhide (see messages
above for more info). If someone of you will face any problems, please let
us know.

Thanks! Regards,

Ondrej

I edited the autoconf check and it seems there are other issues, which are
causing problems. I also contacted upstream and they do not have any
experience with this version working with jdk-11 or jvm-11. I see it as a
high risk to "somehow" rebuild it
 and push it to rawhide. In addition, there is a deprecation announcement
to whole libdb, so I consider this as a good first step.

Thanks,
Ondrej
