jeffsvajlenko / cloneworks Goto Github PK

The path of CloneWorks on my computer is /home/USER_NAME/opt/CloneWorks.

OS: Ubuntu 18.04

With the default config where INSTALL_DIR=., the example test works ok.

Problematic config

Then I set INSTALL_DIR=/home/USER_NAME/opt/CloneWorks, and add export PATH="/home/USER_NAME/opt/CloneWorks/cwbuild:$PATH" to ~/.zshrc.

Failure

I tried cwbuild -i sources -f sources/files -b sources/blocks -l java -g function -c type3line > cwbuild.log in another directory, but I got the following errors (Exception: Broken pipe and Exception: Stream closed ):

Additional Info for debug

I log INSTALL_DIR and LIBS in cwbuild.

With the default setting, their values are:

INSTALL_DIR is  .
LIBS is  ./bin/:./libs/commons-lang3-3.4/commons-lang3-3.4.jar:./libs/commons-exec-1.3/commons-exec-1.3.jar:./libs/commons-cli-1.3.1/commons-cli-1.3.1.jar:./libs/commons-io-2.4/commons-io-2.4.jar
"./cfprocessors/txl_normalization" "r" "." "java" "function" extract

After modification, they are:

INSTALL_DIR is  /home/USER_NAME/opt/CloneWorks
LIBS is  /home/USER_NAME/opt/CloneWorks/bin/:/home/USER_NAME/opt/CloneWorks/libs/commons-lang3-3.4/commons-lang3-3.4.jar:/home/USER_NAME/opt/CloneWorks/libs/commons-exec-1.3/commons-exec-1.3.jar:/home/USER_NAME/opt/CloneWorks/libs/commons-cli-1.3.1/commons-cli-1.3.1.jar:/home/USER_NAME/opt/CloneWorks/libs/commons-io-2.4/commons-io-2.4.jar
"/home/USER_NAME/opt/CloneWorks/cfprocessors/txl_normalization" "r" "/home/USER_NAME/opt/CloneWorks" "java" "function" extract

I have a test function like this:

`
public org.jooby.Route.Definition apply(final org.jooby.Route.Definition route) {

        this.attrs.build().forEach(route::attr); **
        if (this.name != null) {
            route.name(this.name);
        }

        if (this.prefix != null) {
            route.name(this.prefix + "/" + route.name());
        }

        if (this.consumes != null) {
            route.consumes(this.consumes);
        }

        if (this.produces != null) {
            route.produces(this.produces);
        }

        if (this.excludes != null) {
            route.excludes(this.excludes);
        }

        if (this.mapper != null) {
            route.map(this.mapper);
        }

        if (this.renderer != null) {
            route.renderer(this.renderer);
        }

        return route;
    }

`
When I run this test case with command './cwbuild -i test/ -f test/ana.files -l java -b test/ana.fragments -g function -c type3token', I only got an empty fragments file.
Then I delete line ** (this.attrs.build().forEach(route::attr);) and seemed to work well. Why is that? Does it mean that it can not recognize the symbol like :: or?

src/detection/GTF/GTFHashMap.java

when updating gtf,if there is a same token in gtf before,gtf will not be updated,like this:
@OverRide
public void add(String term, long num) {
AtomicLong value = map.putIfAbsent(term, new AtomicLong(num));
if(value != null)
value.addAndGet(num);
}

maybe we should change to :
@OverRide
public void add(String term, long num) {
AtomicLong value = map.putIfAbsent(term, new AtomicLong(num));
if(value != null){
value.addAndGet(num);
map.put(term,value);
}
}

Dear Jeffrey,
I tried to test CloneWorks with the Code of the Testing Chapter in the readme.
But the Code

./cwbuild -i example/JHotDraw54b1/ -f example/JHotDraw.files -b example/JHotDraw.fragments -l java -g function -c type3_conservative

is not working because the type type3_conservative can't be found. I tried to use type1 - another configuration from ./config - and its working. So maybe just change it in the readme.md?
