Re: [google-appengine] Re: X-AppEngine-City
The Maxmind Webapi is working well for me now. But I'm curious whether App Engine will ever provide this out of the box. perhaps the maxmind webapi would be another solution. > i've not tried ipinfodb, but i am using maxmind on several projects > (webapi and local db). > the webapi works quite well for me when caching results locally for a > short time. > when using the webapi i've sometimes put in the local db as a backup > solution in case the webapi times out etc. > -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.

Re: [google-appengine] X-AppEngine-City
Jeff, I didn't even consider using their Java api. The idea of keeping the data in memory on App Engine is absurd. I'm surprised you thought that might work. I'm following an approach similar to Ikai's in his blog post: http://ikaisays.com/2010/08/11/using-the-app-engine-mapper-for-bulk-data-import/ As you can see, he parses the Maxmind file into City and Zip entities so that he can do lookups by Key. Unfortunately I don't think this works to lookup a City from an IP address - because you have to scan a series of IP ranges in the underlying data (the data is not actually very complex). Brandon, "what's in it for me" is a good question to ask - on both sides of the transaction. In my case, it's a commercial app so why would I rely on your service? Who are you and how do I know you will be around in 6 months or 6 years? I don't mind paying for a service but I would prefer to pay for a service with some weight behind it. Juha, jsapi lookups are limited by daily quotas and questionable for a commercial app without paying an alleged $10,000 licensing fee for Google Maps Premium. - Krishna -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.

Re: [google-appengine] X-AppEngine-City
Jeff, Which code is horrific? I was going to load the Maxmind database into custom entities - so I don't see why it's a big deal if it's tough to load a split file a single time. After it's loaded into custom entities all of my geo queries would run against the datastore. Maybe I'm misunderstanding you.

Re: [google-appengine] X-AppEngine-City
Ikai, Uploading the data is a one-time cost, yes - but not an inexpensive one. And doing a city lookup upon each login is expensive because of the need to scan IP ranges in the Maxmind database. I assume this will require indexing but I don't know how expensive an IP/city lookup is going to be in terms of how many underlying datastore queries will need to be performed. Third party apis are out of the question (this is a commercial app) and a professional geolocation license for Google Maps allegedly costs $10,000 - which is also out of reach. For these reasons, it is disappointing that App Engine stopped short of implementing X-AppEngine-City - which would have saved countless developer hours and expense. - Krishna On Thu, Oct 6, 2011 at 4:54 PM, Ikai Lan (Google) wrote: > Krishna, > > It's a one time cost.

[google-appengine] Why does "appcfg.py request_logs" not accept "java" as a valid runtime in app.yaml?
Is there a way for a Java app to call "appcfg.py request_logs"? When I try to do so, I get this error which goes away if I kludge my app.yaml by changing the runtime value from 'Java' to 'Python': appcfg.py request_logs --application=s~example --email=exam...@gmail.com--num_days=1 . C:\request_logs.txt > Host: appengine.google.com > Error parsing yaml file: > Unable to assign value 'java' to attribute 'runtime': > Value 'java' for runtime does not match expression '^go|python|python27$' > in ".\app.yaml", line 2, column 10 But I don't want to have to remember to change the runtime value every time. Is there a way to avoid this kludge and download request logs for my Java app? -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
