Hi Pierre,

Le 26/10/2022 à 16:47, Pierre Gruet a écrit :

My question is: apart from time to work on the package, is there any
reason we should remain with antlr4 4.7.2 in Debian although 4.11.1 has
been released upstream?

Yes, antlr is the kind of package you don't want to upgrade, because
it's likely to break another package and debugging a language grammar
without upstream consent is really the last thing you want to do. So as
long as it works, I'm not touching it :)

The safe way to upgrade antlr4 is to:
- check the version used by the reverse dependencies
- if the lowest version used is above the package version, then upgrade
- if the version you need is still higher, checkout the project, update
the antlr dependency and run the upstream test suite (not from the
Debian package build since tests are sometime disabled)
- if all goes well, upgrade the antl4 package
- if if not, clone the package to keep the previous version (we had to
do this with antlr 3.2)

Good luck!

Emmanuel Bourg

Hi Pierre,

java.io.InvalidClassException: org.antlr.v4.runtime.atn.ATN;
Could not deserialize ATN with version 4 (expected 3)

what exactly does it deserialise there?

Is this maybe something that we should build from source in the
Debian packaging instead?

That would also solve your issue, probaby with less effort and
additionally more DFSG-correctness ☺

bye,
