Find policy names in deferred javascript (with patch)

[GoogleCodeExporter]

Using code splitting, when a service is not included in the initial code, the 
policy name for this service is not found in the permutation html but in the 
deferred js file.

I changed the fetchSerializationPolicyName method to crawl the deferred js 
files.

Here is the modified method:

//////CODE//////////

public static Map<String, String> fetchSerializationPolicyName(String 
moduleBaseURL) throws IOException{
    Map<String, String> result = new HashMap<String, String>();

    moduleBaseURL = moduleBaseURL.trim(); //remove outer trim just in case
    String[] urlparts = moduleBaseURL.split("/");
    String moduleNoCacheJs = urlparts[urlparts.length-1] + ".nocache.js";   //get last word of url appended with .nocache.js

    String responseText = "";
    responseText = getResposeText(moduleBaseURL + moduleNoCacheJs);
    // parse the .nocache.js for list of Permutation name
    // Permutation name is 32 chars surrounded by apostrophe
    String regex = "\'([A-Z0-9]){32}\'";
    Pattern pattern = Pattern.compile(regex);
    Matcher matcher = pattern.matcher(responseText);
    // while (matcher.find())
    if (matcher.find()){
        /// BEGIN CHANGE////
        String permutationName=matcher.group();
        permutationName = permutationName.replace("\'", "");

      // Load the first permutation html file
      String  permutationFile =permutationName+ ".cache.html";
        /// END CHANGE///
      responseText = getResposeText(moduleBaseURL + permutationFile);
      matcher = pattern.matcher(responseText);
      int i = 0;
      while (matcher.find()){
        String policyName = matcher.group();

        policyName = policyName.replace("\'", "");

        if (0 == i++){
          // The first one is the permutation name
          continue;
        }
        responseText = getResposeText(moduleBaseURL + policyName + GWT_PRC_POLICY_FILE_EXT);
        result.putAll(parsePolicyName(policyName, new ByteArrayInputStream(responseText.getBytes("UTF8"))));
      }
        /// BEGIN CHANGE////
      //Iterate over fragment files
      boolean exists=true;
      int fragmentIndex=1;
      while(exists){
         String url= moduleBaseURL+"deferredjs/"+permutationName+"/"+fragmentIndex+".cache.js";
         try {
                 responseText = getResposeText(url);
              matcher = pattern.matcher(responseText);
              i = 0;
              while (matcher.find()){
                String policyName = matcher.group();

                policyName = policyName.replace("\'", "");

                responseText = getResposeText(moduleBaseURL + policyName + GWT_PRC_POLICY_FILE_EXT);
                result.putAll(parsePolicyName(policyName, new ByteArrayInputStream(responseText.getBytes("UTF8"))));
              }

        } catch (IOException e) {
            //no found
            exists=false;
        }
         fragmentIndex++;

      }
        /// END CHANGE///

    }

    if (result.size() == 0){
      logger.warning("No RemoteService fetched from server");
    }else{
      dumpRemoteService(result);
    }

    return result;
  }

//////END CODE//////////

I made that quickly but it works for my installation.

Thanks for submitting that patch, it worked for me right off the bat. But damn 
there are tons of warnings. I wonder if you happen to have patched the problem 
when it complains about certain classes not being found in the serialization 
policy file.

The patch you've submitted will be integrated into the next version (probably 
0.6) of the library as I will need to make some larger changes to the testing 
system to verify this feature. Thanks
