I've noticed that there are some questions that are getting asked over and over again, and the best answers are scattered across many posts. This is a stab at compiling the wisdom of the group and making it easy for everyone to get the answers they need fast. So the next time someone drops their laptop into a pit of alligators and then realizes it had the only copy of their super awesome app, we can just point them here instead of snarkily explaining the virtues of source control and backups.
This is just a start. I included some specific requests for help/ feedback in << >> . any other suggestions are welcome. -peter -------------------------------- App Engine FAQ's Q: I accidentally deleted my source code from my hard drive. How do I download my source code from Google's servers once I upload it using dev_appserver.py? A: You can't. There are several steps you can take to improve your situation. In general, using a source control tool is a good way to keep your code safe. Google offers one such tool for free: http://code.google.com There are many other options for source control out there, and using app engine as your backup is not the best one. <<suggestions for other free source repositories welcome>> However, if you really want to access your uploaded code directly, you can include some code in your app that will allow you to download your code as a zip file: http://groups.google.com/group/google-appengine/browse_thread/thread/8f68d6a3e61fee8/aa5f0e44d14116ee?lnk=gst&q=zipme#aa5f0e44d14116ee << any other suggestions for revision-control-phobes? >> For shell like access to your uploaded code, check out http://shell.appspot.com/ http://con.appspot.com/ Q: When is App Engine going to support my favorite programming language? Q: When is App Engine going to support billing for higher quotas? A: The official roadmap is here: http://code.google.com/appengine/docs/roadmap.html Beyond that, the GAE team has not made any promises about particular features. Q: I am confused about High CPU warnings in my logs or in my dashboard. A: The mcycles number included in log entries does not include mcycles spent on API calls (like datastore or memcache calls). The number in the dashboard includes the mcycles used in both your code and API code. This is why the dashboard number is usually higher. <<I would love someone to verify that I got this right and not backwards. Also, if someone feels up to giving a clear, concise description of the CPU quota issue in general that would probably be helpful.>> Q: How do I use my favorite SQL feature in GQL? A: First, you must understand that SQL and GQL are very different. Not all features of SQL are available in GQL, just like not all features of GQL are available in SQL. Here are a few pointers on how to duplicate some common SQL features using the Datastore: * To simulate count(*) in the Datastore, you should construct a sharded counter. The datastore does not give you a way to count all your entities. You must maintain a count yourself. A sharded counter is the currently accepted best practice for doing this. For example implementations, see: http://github.com/DocSavage/sharded_counter/tree/master/counter.py (by Bill Katz) http://paste.blixt.org/1581 (by Sylvain?)

How can I get access? What's wrong with just using my email address? A: Look at http://code.google.com/appengine/kb/sms.html <<does anyone from china have any better advice? i'm from the US so i have no idea>> --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.
