How to exclude all classes except for one in chord.ext.scope.exclude?

[Dongcai Shen]

Dear Chord maintainers,


Chord is very useful. I appreciate your great work. I stumble on a problem but don't know how to solve: exclude all classes except for one in chord.ext.scope.exclude. Would you mind giving me some hints?

For example, I want to exclude all classes with prefixes "java." except for java.lang.Runnable. I know that by this:
chord.ext.scope.exclude=java.
we exclude every class that starts w/ java.. However, is there any way to exclude every class except for java.lang.Runnable?

Many thanks.

Unfortunately, no. Worse, the exclusion is deep in the joeq library
and therefore a pain to fix. The thing I usually did was wrote a
simple stub implementation.

I believe JChord has this for Runnable. But I never looked hard at
that. For my work, I actually did a conservative approximation and
assumed that all Runnables that were ever constructed would get run.

Thanks, Ariel. I will try stub.

Btw, I followed the instruction of conf_analyzer (the README under its directory) and tried the hadoop example.

ant -Dchord.work.dir=`pwd`/examples/hadoop20/

The corresponding chord.properties has been changed to the actual address of hadoop jar in my machine. But, I got this error in log.txt:

It seems classes specified in multiple entrypoints are not analyzed and put in domain M. I am trying the multiple entrypoints in other scenarios but this seems not working (the same error). Maybe I miss sth, would you mind giving some hints? I am a newbie for chord. Thanks a lot.

Hi Dongcai,

I recently got this problem when running conf_analyzer by the instruction in the README file. I have no clue about it. Did you solve the problem? If yes, could tell me how to handle this problem?  Thanks a lot.
