Hi all,
I'm looking at extending the version.sh output
And version.bat ?
to print the version of apr,
openssl (including when used via FFM), and tcnative that are available on
the system (so usable, but not necessarily configured for use in the
server.xml).
So it will pull in the configuration from setenv.sh (like it does now)
and then report the libraries it could load if configured in server.xml
given the current environment? So if there are multiple versions if
Tomcat Native, it will list them both?
I like it.
I also think it could be useful to list the name and version
information from third party jars in lib/.
OK. Initially, I wasn't sure about ecj.jar but given we tell folks they
can replace it with a newer version then listing it does make sense.
Basically I want to pull all of
the library version information from the log for the libraries loaded and
have it returned here so that version.sh gives a full picture of the
environment and not just the tomcat, JDK, and OS output.
Obviously this requires extending o.a.c.util.ServerInfo, which is a bit
more involved than I thought it might be :) I would need to add the
classpath and catalina home and base to the catalina.sh script's execution
of the version block so that ServerInfo has access to those.
Makes sense.
I think I can
access all the things I want with reflection to init the classes
Is there any refactoring we can do to reduce the amount of reflection
required? I'm thinking of AprLifecycleListener, JniLifecycleListener etc.
and get
version info, and use java.util.jar.* to check the jars in lib/. Before I> dive
too much into implementation I wanted to ask if anyone has thoughts
about this proposal or if there are suggestions for other useful things we
could add. If there's no objections, I'll add submitting a PR to my TODO.
Maybe the include the values of:
CATALINA_BASE
CATALINA_HOME
java.library.path
Here's some example output:
```

Looks good.
