[Anthill-pro] Alternate means for retrieving the subversion revision number

[Jeff Adamson]

Chris,
	Since the stamps on each buildlife is the most recent revision included in that buildlife, the fall-back strategy we have typically been using for revision based stamping is to parse the stamp from the prior build.  The SvnModule (combined with the SvnSourceConfig and SvnRepository) is really just a means of describing the layout of the repository used for doing checkout/labels/....  It does not readily provide any info relating to changelogs or revisions of the current buildlife.


A Scripted Stamping Template along the lines of:
import com.urbancode.vcsdriver3.*;
import com.urbancode.anthill3.runtime.scripting.helpers.*;

int getMaxChangeSet(ChangeLog[] changelogArray) {
  int result = 0;
  for (int i = 0; i < changelogArray.length; i++) {
    ChangeSet[] changesetArray = changelogArray[i].getChangeSetArray();
    for (int j = 0; j < changesetArray.length; j++) {
      ChangeSet changeset = changesetArray[j];        
      id = changeset.getId();
      // edit out the "r" character for svn
      if (id.startsWith("r")) {
        id = id.substring(1);
      }
      int num = (new Integer(id.trim())).intValue();
      if (num > result) {
        result = num;
      }
    }
  }
  return result;
}

int highestChangeset = getMaxChangeSet(ChangeLogHelper.getChangeLogArray());

// If there is no changelog, look up the most recent failed and good build
// and take the highest number. We assume that the version number will
// be the first stamp.
if (highestChangeset == 0) {
 lastSuccess = BuildLifeLookup.mostRecentSuccess();
 lastFailure = BuildLifeLookup.mostRecentFailure();

 if (lastSuccess != null) {
   try {
     highestChangeset = new Integer(lastSuccess.getLatestStampValue()).intValue();
   } catch (NumberFormatException e) {
     // stamp was not recognized
   }
 } 
 if (lastFailure != null) {
   try {
     highestChangeset = new Integer(lastFailure.getLatestStampValue()).intValue();
   } catch (NumberFormatException e) {
     // stamp was not recognized
   }
 }
}
return ""+highestChangeset;
//------------

I hope this is helpful,
Jeff
