ChangeVectorCollector

Uses the BIC information collected from DPminer to embed the BICs into a vector. The vector embedding is done by defining the type of changed nodes and their AST using an algorithm called Gumtree.

How to build: Gradle

 $ ./gradlew distZip 

or

 $ gradle distZip 

After the command do follwing to unzip the distZip:

 unzip ./build/distributions/change-vector-collector.zip 

The executable file is in build/distributions/change-vector-collector/bin

If you have trouble to build using gradlew, enter

$ gradle wrap

Project components

1. making buggy training set

   a. -r --repo (get BIC to BBIC)

   1. description: collects BBIC from BIC, which is needed before gumvec collection. BBIC contains the information of changes of before BIC.
   2. example:

    ./ChangeVectorCollector/change-vector-collector/bin/change-vector-collector -r -u "https://github.com/haidaros/defects4j-math" -i "/Users/jihoshin/Downloads/" -o "/Users/jihoshin/Downloads/" 

   b. -g --gumtree (BBIC to x and y)

   1. description: applies gumtree algorithm on BBICs and outputs change vectors and the information (label) file. 2.example:

    ./ChangeVectorCollector/change-vector-collector/bin/change-vector-collector -g -u "https://github.com/apache/commons-math" -i "/Users/jihoshin/Downloads/" -o "/Users/jihoshin/Downloads/" 

2. making clean training set

   a. -q --clean (repo to x and y)

   1. description: collects clean changes in a repo. This is used to collect clean train sets.
   2. example:

    ./ChangeVectorCollector/change-vector-collector/bin/change-vector-collector -q -u "https://github.com/apache/commons-math" -i "/Users/jihoshin/Downloads/" -o "/Users/jihoshin/Downloads/" 

3. making test set (combined)

   a. -a --all

   1. description: collects all changes (both buggy and clean) in a repo. This is used to collect test instances.
   2. example:

    ./ChangeVectorCollector/change-vector-collector/bin/change-vector-collector -a -u "https://github.com/apache/opennlp" -i "./assets/" -o "./assets/" 

4. miscellaneous

   a. -z --zero

   1. description: remove empty vectors and key duplications.
   2. example:

    ./ChangeVectorCollector/change-vector-collector/bin/change-vector-collector -z -u "https://github.com/apache/tez" -i "./assets/rm_zero/out/" -o "./assets/rm_zero/out/out2/" 

   b. -l --local

   1. description: loads BBIC from an existing file in the local system.
   2. example:

    ./ChangeVectorCollector/change-vector-collector/bin/change-vector-collector -l -u "https://github.com/apache/commons-math" -i "./assets/BBIC_commons-math.csv" 

   -o "./assets/"

   c. -d --defects4j

   1. description: makes test files for defects4j specifically (different in collecting BIC).
   2. example:

   ./ChangeVectorCollector/change-vector-collector/bin/change-vector-collector -d -u "https://github.com/apache/commons-csv" -i "./assets/d4j/" -o "./assets/d4j/"
