Subject [jira] Created: (PIG-654) Optimize build.xml
Date Sun, 01 Feb 2009 21:03:59 GMT
Optimize build.xml

                 Key: PIG-654
                 URL: https://issues.apache.org/jira/browse/PIG-654
             Project: Pig
          Issue Type: Improvement
          Components: impl
    Affects Versions: types_branch
            Reporter: Daniel Dai
            Assignee: Daniel Dai
            Priority: Trivial
             Fix For: types_branch

Build process can be faster. Here is the issues slow down the build process:
1. Should change test/org/apache/pig/test/utils/dotGraph/Dot.jjt to DOTParser.jjt. [jjtree]
assumes the output file name the same with the input file name, otherwise, it will recompile
every time
2. Delete src/org/apache/pig/backend/hadoop/executionengine/physicalLayer/relationalOperators/POPostCombinerPackage.java
and src/org/apache/pig/impl/plan/SplitIntroducer.java, both classes are empty and generates
no class file. Ant will recompile them every time since it do not see the output class file.

I do not know how to create a patch with file deletion and rename, so I describe the actions
1. mv test/org/apache/pig/test/utils/dotGraph/Dot.jjt test/org/apache/pig/test/utils/dotGraph/DOTParser.jjt
2. rm src/org/apache/pig/backend/hadoop/executionengine/physicalLayer/relationalOperators/POPostCombinerPackage.java
3. rm src/org/apache/pig/impl/plan/SplitIntroducer.java
4. apply patch to change build.xml (Dot.jjt -> DOTParser.jjt)
