Re: [google-appengine] where to put credentials?
I use resource files to store credentials and on app start i copy them in to a global config entity en the datastore. I cache it for fast access aswell.

Re: [google-appengine] How to get the path of a file saved in blobstore ?
Hello Anuja, When you upload a file to the blobstore, in the /_ah/upload callback you can grab the BlobKey that was uploaded: BlobstoreService blobstoreService = BlobstoreServiceFactory.getBlobstoreService(); MapString, ListBlobKey blobs = blobstoreService.getUploads(request); BlobKey *blobKey* = blobs.get(file).get(0); You need that blobkey to access the file again. If you want to accecss the file later, you might want to store it somewhere in the datastore. With the BlobKey you can retrieve a byte[] of the file to do whatever you want: byte[] file = blobstoreService.fetchData(*blobKey*, 0, BlobstoreService.MAX_BLOB_FETCH_SIZE-1); Hopes that helps. Good luck! 2013/11/14 anuja bothra anujabot...@gmail.com Hi, I have data in an excel sheet. I need to read that data and save it to the datastore. I am able to upload the excel to blobstore.

Re: [google-appengine] How to get the path of a file saved in blobstore ?
Hello Anuja, No, that is not possible because the actual file is not in the filesystem. But with the byte[] you can easily get a InputStream checkout: http://stackoverflow.com/questions/1802123/can-we-convert-a-byte-array-into-an-inputstream-in-java InputStream myInputStream = new ByteArrayInputStream(file); POIFSFileSystem myFileSystem = new POIFSFileSystem(myInputStream); 2013/11/14 anuja bothra anujabot...@gmail.com I actually wanted to parse the file in POI since I already had written code for that in a local app. FileInputStream myInput = new FileInputStream(filePath); POIFSFileSystem myFileSystem = new POIFSFileSystem(myInput); I need the filePath (the excel file's path) so that I can just pass that and reuse the code that I had already written. Is that not possible ?

Re: [google-appengine] add-on Google Cloud Storage to an existing GAE project
Hello again, For clarification on you last statment: *The goal is to store data from that project in GCS.* You can create a new entire project in GCS that has nothing related to your ABC project, and give that project permissions to your GCS buckets thorugh the GCS ACLs. The only thing you need is to gather the Service Account Name from you ABC's AppEngine console under Application Settings. Its looks like abc-proj...@appspot.gserviceaccount.com. Take that email and give it permissions in the GCS bucket you want to store your files.

Re: [google-appengine] Re: Over index creation quota
I dont know what kind of model do you have and what you can do with it, but for example with this entity: * Record* @Id Long id String user Boolean newsletter; //- indexed Boolean notifications; //- indexed String choice; //A,B or C - indexed How about splitting the entity this way? *RecordNewsletter* @Id Long id String user Boolean choiceA; Boolean choiceB; Boolean choiceC; *RecordNotifications* @Id Long id String user Boolean choiceA; Boolean choiceB; Boolean choiceC; As the 200 limit index count is only for composite indexes, with this model you have 0 indexes count.

We can increase the index quota, but only in exceptional circumstances. We store the data in expando model which is very huge.. The no of columns at the minimum will be around 300.

Re: [google-appengine] Re: Over index creation quota
Generally speaking, If I'm not too mistaken, your approach to my scenario wouldn't reduce write operations, it would just reduce index number, but in return require manual indexing via additional models, kind of like moving around the limitation, not that I'm against it We were talking about reducing indexes, but that usually comes with more read or write operations. The reads operations can be reduced with memcache or other caching mechanism. What you can do is delete all the indexes you think you don't need and test your application in a dev environmet. If there are any index needed that you don't define, the app is gonna crash with a handy log message saying which index is needed. As a rule, i always expect that error development logs prior to add the index to my appengine-index.xml Doing that i'm totally sure i don't have unused indexes defined. Cheers and good luck with your index crusade! 2013/10/19 Kaan Soral kaanso...@gmail.com In my scenario, there is a query with a sort order and there are optional filters, each optional filter doubles the index number Generally speaking, If I'm not too mistaken, your approach to my scenario wouldn't reduce write operations, it would just reduce index number, but in return require manual indexing via additional models, kind of like moving around the limitation, not that I'm against it An approach that keeps the simplicity but reduces the index number would be great I wonder what would happen if I only indexed each filter/property in a single index with the sort order and remove other combinations I'm not sure what would happen with a query that misses only one property from that index for example, does the system use that index, can error occur with huge datasets etc. I'm probably not going to exceed the 200, but I was thinking about refactoring a property from that index, which would cause a temporary increase in index numbers before vacuuming, which might cause issues Thinking about my case now, it might be a good idea to think about encoding the combinations and putting them inside a repeated property to be queried This wouldn't change the write operations, however would probably reduce indexes drastically Thanks for the advice and thanks for making me think :) On Saturday, October 19, 2013 1:24:32 PM UTC+3, Alejandro González Rodrigo wrote: I dont know what kind of model do you have and what you can do with it, but for example with this entity: * Record* @Id Long id String user Boolean newsletter; //- indexed Boolean notifications; //- indexed String choice; //A,B or C - indexed How about splitting the entity this way? *RecordNewsletter* @Id Long id String user Boolean choiceA; Boolean choiceB; Boolean choiceC; *RecordNotifications* @Id Long id String user Boolean choiceA; Boolean choiceB; Boolean choiceC; As the 200 limit index count is only for composite indexes, with this model you have 0 indexes count.

Re: [google-appengine] How to prevent overwriting an entity simultaneously?
In few words: whats you need are transactions.
Transactions are there to solve your problem. stop making rutines and
subrutines to solve a problem that si already solved.
Using a framework usually mitigates the learning curve. I don't know if you
are already using a framework or library to handle datastore stuff or if
you are using Java, phyton or PHP but you have a lot of examples out there.
If you give us more info about technologies and librareis used maybe we can
give you some code or links to good tutorials to solve your problem or
learning about transactions.
Cheers.

I've implemented routines to handle contention at a large level, a custom
pipeline implementation, there also also basic checks to prevent

However there are some operations that require no overwrite to occur, for
example:
- Signup related updates, email, external_user_id etc
- Email verification
- User information updates
When these get overwritten by another update simultaneously, it creates a
really disturbing experience
I've done a lot to prevent these, yet they do still happen rarely, and by
rarely it seems 1%, a lot
My plan is to dive into more custom routines to implement make sure
routines / prevention routines
I'm wondering whether there is something really basic I'm missing that
achieves what I want to do
For example I've never used transactions, without actually using it,
learning from the use cases, the documentation of transactions were
meaningless to me
I would appreciate any advice
(I'm also extremely unlucky, or lucky, tested my new app with ~10 users,
all of them experienced unique problems, some issues that occurred probably
have 1/1 probability of occurrence, a user triggered a second signup
request, probably by page refresh, it would only cause an issue if the last
part of the routine would execute around the same millisecond, and it did)

[google-appengine] Re: GAE Newbie question - User Login page
Hello, There is a lot of ways of doing and securing your application. GAE has an UserServicehttps://developers.google.com/appengine/docs/java/gettingstarted/usingusers and easy tutorials the get it rolling. You have security constrainshttps://developers.google.com/appengine/docs/java/config/webxml#Security_and_Authenticationas well, that can secure the urls you want and the only thing you need is to define them in your web.xml To secure services i would use Filtershttps://developers.google.com/appengine/docs/java/config/webxml#Filtersrather than implementing the security in each servlet doGet/doPost, this way you have all security centralized and the same for all servlets calls. Cheers!

I am stuck on creating the log-in page using OpenID. If I want every single page to require the user to be logged in to even view, how would I achieve this using servlets? Would I be putting in user login status at the beginning of doGet() of all servlets and if the user is not logged in, redirect to the log-in page and redirect back to the servlet? This seems like some boiler-plate code, is there some kind of configuration I can do to achieve the same thing easily? Also, I do appreciate Google's openID documentation, it is not detailed enough for me to understand how the work flow is in this framework. Is there a helpful tutorial site anyone knows? Had not much luck in google searches either... Thanks guys! -- You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Re: Securing web services
As far as i know there is nothing in appengine to do something like that (securize web services / API / endpoints ) you need to do it on your own. I dont know your whole scenario, but a standard way to secure web services is oAuth2 with the Client Credentials flow (in your case, with no end users). This way the app that wants to call your services, needs to be identifyed before he can request nothing to you. What you need to do is oAuth provider in your server to handle all authentications and store clients keys and secrets. There are some good opensource libraries to handle all oAuth stuff If you dont want go that far, you can keep it simplier with an API-Key schema, but is less secure.

We need to secure these endpoints such that only specific applications can access them. This will be programmatic access, so there will be no user involvement (i.e. no login screens). Looking at the documentation it seemed like service accounts would give us this ability, however this only seems to give access to the google API. Is there a standard way to secure appengine web services, or do we need to roll our own solution?

[google-appengine] Re: Problems with custom domain and SSL, stopped working
I have exactly the same problem. The custom domain was working for a couple of months and suddenly, last night, its stop working. Any info to fix this problem would be appreciated, since this is an issue with an application in a production environment. Thanks.
