Perhaps the build ID request should use the git hash instead of svn revision
now?

 
     # Creates a try job description.
+    # Always use Git hash to post build request since Commit positions are
+    # not supported by builders to build.
     job_args = {
-        'revision': 'src@%s' % svn_revision,
+        'revision': 'src@%s' % revision,
         'bot': bot_name,
         'name': build_request_id,
     }
