问题 I just faced a problem with writing data to Google Cloud Storage using AppEngine FileService. The problem is timeout related as I think. I created new GS file and write data to it using Tasks. Every task closes FileWriteChannel with close(). But closeFinally() is called in about 2 hours after last write (It is required by my DataFlow). So I do not see any file in GS. Is it any timeoute between last write and closeFinally()? 回答1: There is no timeout between calls to close() and closeFinally()

问题 We have three projects in Google App Engine, each of them have a custom sub-domain name mapped to it like this: Project A: projecta.domain.com Project B: projectb.domain.com Project C: projectc.domain.com That worked very well until we added a wildcard ssl-certificate to Project A. Suddenly all three subdomains are mapped to Project A. They appeared under Project A, custom domains (Project A->App Engine->Settings->Custom Domains) and not one under each Project B and Project C, and when

问题 Do I need to pay to for a resident instance? The information available is confusing to me? I want to enable the "always on" feature for my java app. Thanks. 回答1: You do need to pay for a resident instance - just set the number of minimum idle instances to however many resident instances you want (3 is similar to the "Always On" feature). Some info about idle instances from the Applications page (where you set it): The Idle Instances slider allows you to control the number of idle instances

问题 I have recently worked through a bunch of kinks making cross-domain ajax calls to a GAE app and it is working beautifully, however, I am trying to set an http session id when making said service call and it is working fine, except that every time I perform the request, the session is null again. I'm assuming that this is because an ajax call and not making the request over http? How can I go about this? 回答1: Session tracking is usually done with cookies. If you are using Cross-Origin Resource

问题 I am trying to add a transaction to keep from creating two entities with the same attribute. In my application, I am creating a new Player each time I see a new Google user logged in. My current implementation occasionally creates duplicate players when multiple json calls are made by a new Google user within a few milliseconds. When I add the transaction like the one commented out here, I get various errors. What is the easiest way to ensure that I never create two player entities with the

问题 I'm currently working on an application that require me to deploy onto Google App Engine Server. My application runs perfectly fine locally on port 7777. However, when I deploy onto GAE, It starts to give me this error - java.lang.IllegalStateException: Committed and it just returns me a "null" in the GAE log. There's no error.

问题 I am creating a large database application in Google App Engine Go. Most of my pieces of data are small, so I have no problem storing them in Datastore. However, I know I will run into a few entries that will be a few megabytes big, so I will have to use Blobstore to save them. Looking at the reference for Blobstore, it appears that the service was mainly intended to be used for files being uploaded to the service. What are the functions I need to call to store arbitrary data in the Blobstore

问题 With Django-nonrel on GAE, how do I do I load in a fixture to the server after deploying? I'm able to do it locallay via python manage.py loaddata fixturename But how can I do it on a deployed app that is already on appspot.com? 回答1: I believe the answer is python manage.py remote loaddata fixturename with an additional 'remote' word. I've tested that (about five minute before I type this). It will prompt for your gmail account and password. You also need to enable remote_api in app.yaml (if
