[google-appengine] Re: How to take your Gmail ID as AppEngine ID?
Thank you Barry! Now I know what the problem is. When I registered this Gmail account I was in Germany, where there are legal issues between Google and one guy over the "Gmail" name. So, if you want to register a Gmail account from a German IP address, Google gives you an email with "@googlemail.com" ending. And Google App Engine refuses to create an App with your Gmail ID (or better said GoogleMail ID) if you have a "@googlemail.com" email. And this IS A REALLY ANNOYING BUG! Virtually most of the German and UK Gmail users are stripped the right to take their Gmail ID as their AppEngine application name. GOOGLE PLEASE FIX IT! And as far as I know, we, users with "@googlemail.com" addresses, can do nothing to make it work with GAE, as we are not able to choose between "@gmail.com" and "@googlemail.com" as our primary address or switch to "@gmail.com" at all. Can I report it somewhere as a bug? Do GAE developers have a public bug tracking system as e.g. Android?

[google-appengine] downloading state of datastore
I want to allow users to download the current state of my app data. There will be around 17MB of data over ~200K+ records, which makes me concerned about timeouts.

So you are not getting any actual error messages? Do you see requests showing up in the request log when expected? When you tell your app to do something does a request show up?

[google-appengine] [Billing rates] Billing is not feasible enough
I develop Facebook applications, I would really like to use AppEngine for future but I think billing should be more feasible. I have 4 million users, If I decide to email users every day, for an abridged summary, It would cost me 200$'s and I could only email 2 million users. According to my calculations If I use AppEngine the cost will be very very close to the income itself. In my opinion emails should be $0.1 instead of $0.0001 . As for the other rates, they are high too, but nearly feasible high, they could be %50 of what they are now. You could say why Google would lower its income to %50 of what it is now, but I think if they do they could attract more and more users to AppEngine. Instead of CDN or Fileservers people could start using AppEngine, or AppEngine based services. In my opinion server/cloud costs should be at %10 of the income, maybe between %10 and %30, %30 being extreme considering a move in economy can make you lose money. But like I said at current configuration of AppEngine I don't think its feasible to use AppEngine for an Ad income'd application.

Re: [google-appengine] Re: Mixed authenticated and unauthenticated content?
Thanks. Looks like I misunderstood GAE authentication. As I now understand matters, if I enable Google authentication for my app, then it's *available*, but not enforced unless I explicitly code something up using the Auth API, or set up a security constraint in web.xml. Which is perfect.

[google-appengine] Guest Google account?
I use Google Accounts to identificate users of my service. But not all users have registered google accounts. What can I do if I want to allow these users to sign-in to my site with 'guest' account, for example gu...@gmail.com. Should I register such account myself? May be Google have some special accounts for that purpose? Thanks and sorry for my English! -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.

[google-appengine] Re: [Billing rates] Billing is not feasible enough
It would probably be more cost effective to have a page people can visit to get the daily summary, rather than using email. I would also wonder why your pricing structure can't afford 3 cents a month per user to cover the email expense. But without knowing what the application is, I can't really speculate beyond that. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.

[google-appengine] Re: Idempotence & multiple task execution
My use case is as follows - 1. tasks which do not support idempotence inherently (such as deletes, and some puts) carry a unique identifier, which is written as a receipt in an attribute of an entity that is updated in the transaction. 2. When a task arrives carrying a receipt, I check that it does not already exist - so receipted tasks incur an additional, key only, db read This is essentially my algorithm for ensuring idempotence (in situations where it is not inherent) - ignore subsequent executions. If the same task *cannot* be running in parallel, then the check for the receipt can be done outside the transaction that writes the receipt - which has a couple of advantages - a. It can be done up front in the task handler, so I don't have to go all the way through to the transactional write before discovering it already executed b. More importantly, I can reduce the work done inside the transaction - every extra millisecond spent in the transaction locks the entity group, and at scale, those milliseconds can add up - especially on entity groups that are somewhat write intensive. If the same task *can* be running in parallel, then I need to do the receipt read inside the transaction that writes it. It would be a pity to do that extra work in every transaction for a very rare scenario. As stated earlier, it seems that it might be possible for GAE to guarantee that it does not execute the same task in parallel - by ensuring that, for error scenarios like those above (408, client crash, perhaps others), the 2nd execution waits 30 seconds. That has some obvious downsides, but given how rarely it occurs, and given that an app shouldn't be relying on the speed with which a task is executed, it seems like a reasonable trade-off to get a reduction in transactional work for the vast majority of the time - less contention, less CPU, less datastore activity. A simple example is a task which increments a counter - we don't want to increment the counter twice. The problem is the same whether one or many entities are being updated during handling of the task. Do you have many situations where you perform a read that does not result in some sort of update - db update, another task raised, email sent, external system notified etc.? There's a subset of most of these that we want to avoid doing twice. It's the multiple writes, rather than multiple reads causing issues.
