Today, I uploaded a new version for one of my GAE project.
For some reason. the uploading was stopped before it was finished.
When I uploaded it again, it prompts
Error 409: --- begin server output ---
Another transaction by user <My Name> is already in progress for app: s~<My-Project-ID>, version: v2. That user can undo the transaction with "appcfg rollback".
--- end server output ---
I encountered this situation many times before, so I I just run the "appcfg.py rollback" command, it run okay with any problems:
12:00 PM Application: <My-Project-ID>
12:00 PM Host:
appengine.google.com12:00 PM Rolling back the update.
But after the rollback, the "appcfg.py update" command still reports the error shown above.
Bug?
