GAE上传时关于"Another transaction by user *** is already in progress "问题的解决

       今晚上传GAE程序时（appcfg.py update micolog；其中，micolog文件跟appcfg.py在同一个文件夹下），半天不响应。再次上传，提示：
Error 409: --- begin server output ---
Another transaction by user *** is already in progress for this app
and major version. That user can undo the transaction with appcfg.py's
"rollback" command.
--- end server output ---


        以前的挫折多了，有了经验：命令行反馈信息已经说明了问题所在及解决办法。仔细一看，果然如是，见上述返回信息的黑体+斜体部分。于是，appcfg.py rollback micolog ，返回:
......
Server: appengine.google.com.
Rolling back the update.
      再次appcfg.py update micolog ，成功更新项目。
