[jira] Created: (HARMONY-1847) [drlvm] -verbose option does nothing
[drlvm] -verbose option does nothing
------------------------------------
Key: HARMONY-1847
URL: http://issues.apache.org/jira/browse/HARMONY-1847
Project: Harmony
Issue Type: Bug
Components: DRLVM
Environment: Any just java -version test
Reporter: Jean-Frederic Clere
Priority: Minor
java -verbose does not print any information
To debug an application it is very helpfull to know which classes and in which order they are loaded.
Something like what RI gives would be enough.

Xtrace:classloader contains the information but it is too verbose.

[jira] Updated: (HARMONY-1847) [drlvm] -verbose option does nothing
Posted by "Salikh Zakirov (JIRA)" <ji...@apache.org>.
[ http://issues.apache.org/jira/browse/HARMONY-1847?page=all ]
Salikh Zakirov updated HARMONY-1847:
------------------------------------
Attachment: log4cxx-fix.patch
The proper fix to the Log4cxx for autoflushing logging console output is attached as log4cxx-fix.patch.
Instructions on how to apply this patch to DRLVM:
cd .../build/pre-copied/common/LOG4CXX
svn update src/systemoutwriter.cpp src/systemerrwriter.cpp src/writerappender.cpp
patch -p0 < .../log4cxx-fix.patch
'svn update' step is needed as there are conflicting changes in those files.
The patch was submitted to log4cxx-devel mailing list.

[jira] Commented: (HARMONY-1847) [drlvm] -verbose option does
nothing

Salikh Zakirov commented on HARMONY-1847:
-----------------------------------------
By the way, fixing '-verbose:class' output to provide all desired information is an excellent exercise for a person who wants to get involved with DRLVM development :) It will take some reading (mostly in vm/vmcore/src/class_support/*.cpp), and putting calls like
INFO2("class", "Class " << name << " loaded");
to produce -verbose:class output.

--------------------------------------------
Rather than patch locally, can you let us know when there's an update to log4cxx and we can use the fix in there?

------------------------------------------
I think the root cause of the first issue lies in flawed shutdown sequence, so the LogManager has no chance to wrap up. Will check this on Monday.

[jira] Updated: (HARMONY-1847) [drlvm] -verbose option does nothing
Posted by "Salikh Zakirov (JIRA)" <ji...@apache.org>.
[ http://issues.apache.org/jira/browse/HARMONY-1847?page=all ]
Salikh Zakirov updated HARMONY-1847:
------------------------------------
Attachment: workaround-fflush-log.patch
There are two separate issues with -verbose.
First, there is a bug which prevents -verbose to print anything. I suspect this because of missing flush() calls in the logger. The attached workaround-fflush-log.patch provides a dirty workaround, which assumes that logger uses stderr for its output (which is the case by default). With the workaround, the expected output on HelloWord aplication is
GC init called
GC v4.1 Wed Oct 11 22:07:28 2006 (debug)
GC type = 0
GC will use adaptive algorithm selection
min heap size 16 mb
max heap size 256 mb
GC use small pages
Hi!
The second problem is that -verbose:class does not report loaded jar files and loaded classes.
('-verbose' is equivalent to '-verbose:gc -verbose:jni -verbose:class').
