问题 Currently I am working on new App Engine application. Unfortunately it seems that my application uses to lot of resources even for relatively small user number. So I need to determine its bottle necks and optimize them. 回答1: Appstats: RPC Instrumentation for Google App Engine.

问题 As far as I understand from app engine tutorial, entity groups exist only for the purpose of transactions: "Only use entity groups when they are needed for transactions" (from the tutorial) The definition of being in the same entity group is to have the same root.. In that case, what is the use of having more than 1 hierarchy level? That is, why should I use "A -> B -> C" (A is the root, B his son, C his grandson) instead of "A -> B ; A -> C" ? (A, B and C are still in the same entity group

问题 We are offloading certain time consuming tasks using the GAE deferred library and would like to know how can we set the retry limit for those offloaded tasks. We are running into issues where certain tasks are retried for ever as the task would never succeed due to some un recoverable exception. 回答1: According to the documentation the _retry_options of the deferred.defer API can be used to pass retry options to the associated Task() instance: _countdown, _eta, _headers, _name, _target,

问题 I am new to using Google APIs. I followed steps to setup Google Calendar sample code in eclipse using Google client library. I deployed the code to app engine using the cmd command- mvn appengine:update (when tried to deploy through eclipse it gave me an error saying the project is not an App Engine project). Deploying through command line worked and I could launch my web application. Suddenly, after few API request calls, started getting invalid credentials error: error:401 domain:global

问题 Google offers git -> App Engine and git <-> Source Repository , so presumably somewhere it offers Source Repository -> App Engine . But I can't find where... even after twice reading all the Source Repository and App Engine docs I can find, inc. https://cloud.google.com/source-repositories/docs/ . I'd guess the procedure could be How to manually deploy direct from Bitbucket to Google App Engine? modified to access the SR files. But I can find the SR files in the GCS VM. Deleting all the $HOME

问题 I'm getting the following error when trying to fetch an URL with urllib2 in the google app engine: error: An error occured while connecting to the server: Unable to fetch URL: http://www.google.com Error: [Errno 10106] getaddrinfo failed This is the code calling the urllib2 open read methods: def get(self): self.write(urllib2.urlopen("http://www.google.com").read()) self.render_index() Nothing fancy, just a call to the library inside the main handler to ouptut the fetched text.

问题 Under python on my machine I can run datetime.now() to get the local time. If I inspect time.daylight flag it is set to 1 because we are currently in July (hence daylight saving). But if I run datetime.now() on Google App Engine (including the dev server) it doesn't account for daylight saving (british summer time) and returns the wrong time (13:47 instead of 14:47). If I inspect time.daylight in GAE it is set to 0 . How can I get the correct local time? Do I need to change the timezone on my
