[google-appengine] Re: How can I share files (HTML templates) between App Engine modules?
Thanks Nick, Glad my question found the right location in the end. I thought I would reply here just for completeness. I ultimately wanted to know how I can avoid file duplication in my own local repo when sharing application files between modules. The answer on StackOverflow suggests simlinking directories between modules is the only way to go. As Nick suggests I could store my file data in Cloud Storage or the datastore but I want to avoid the complexities of that. I'll accept the StackOverflow answer unless anyone has a better suggestion.

Jeff, Thanks for confirmation and all the extra background information. Dan On Tuesday, May 19, 2015 at 6:55:02 AM UTC+1, Jeff Schnitzer wrote: It isn't the other way 'round, no.

Re: [google-appengine] Re: Creating Unique Entities
Hi Francis, I think I understand exactly what you mean and it's an interesting edge case when designing the datastore transaction system. Somehow within a transaction it needs to record that the 'put' method either expects the entity it is saving to already exist or not exists. What's more this logic needs to kick in only if earlier in the transaction a 'get' bothered to detect if the entity existed in the first place! I hope the designers of the datastore considered this and am sure they have as I have not seen anything to suggest transactional integrity has ever been broken in my apps. I guess you are looking for confirmation though as the way the datastore's internals are described in various don't suggest the edge case is catered for. Maybe you could write a test and run it a reasonable number of times to see if atomicity guarantees break. I would be interested in seeing the results.

Re: [google-appengine] Re: How do I determine the order of HTTP requests?
Thanks for the replies. Robert, The rates come in bursts peaking over a few seconds and tail off quickly over the course of a few minutes. They are generated by users quickly clicking links in web browsers that use AJAX to connect to the GAE cloud. I would like to get the sequential order of these clicks over all users. I had a thought, I could have a 'Request' entity as so: class Request(db.Model): request_id = db.StringProperty() timestamp = db.DateTimeProperty(auto_now_add=True) count = db.IntegerProperty(long) The timestamp property is taken from the instances clock and count property is updated with memcache atomic increment for each new request. I could then use a task to select the Request entities ordered by timestamp and in memory also order by count. The count property takes precedence over the timestamp. The worst case scenario, where memcache is flushed before each new request, would degenerate to a resolution of the clock differences between each GAE instance. I don't expect I would hit the monotonically increasing value performance limitation as Ikai explained. However all I would need to do is not index timestamp and count properties and reindex them at a later date. Then the limitation would be how quickly can I call memcache increment. I don't expect this would be an issue either... In the general case, I think this method would provide the greatest accuracy and tolerate the occasional memcache flush. Relative to the latency variations inherent in the web, this could be a winner. If I needed to be even more specific, I could use Calvin's idea to make sure each GAE instance's clock isn't minutes different from other instances to minimise the disruption when memcache is flushed.

[google-appengine] How do I determine the order of HTTP requests?
I periodically have a large number of requests (thousands) to my site in the space of a few seconds. I need to record the order in which the requests access the site so I can do downstream processing. The order does not have to be exact, I only need resolution down to 1 second: I don't care which order two requests are in if they are 10 ms apart. However I do care which order they are in if they are 1500 ms apart. The only problem is that I cannot figure out how to do this. I though about creating a datastore entity that contains a timestamp for each request to the site. (It doesn't matter if two or more entities have the same timestamp.) However I understand the clocks between machines in App Engine are not necessarily synchronised and could vary wildly. It would be ok for business logic if they only varied by 1-1.5 seconds at the most but I don't think this can be guaranteed. I thought about using memcache's atomic increment function instead of a timestamp for each new request but this could be wiped at any time so is no good. Even if the wipe occurs rarely, I cannot afford it to happen just once. How can I solve this type of problem?

[google-appengine] Re: What's the point of memcache incr decr?
Strom, your use of memcache incr and decr is a great example: Synchronise a memcache counter with the count() of a datastore entity query. I imagine it could be tricky to *exactly* synchronise the memcache counter with the datastore if the memcache counter did get purged. Calvin, I had a look at the PubSubHubbub code and it seems they use memcache incr to determine if a subscriber is performing a DOS attack. In this case it doesn't really matter if the memcache counter gets wiped. Any more examples memcache incr/decr use? -- You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] What's the point of memcache incr decr?
Hi All, What are some use cases of memcache incr decr? I just don't see where a distributed atomic increment/decrement function would be useful when you know it could be wiped and reset at any point. People suggest periodically saving a memcache counter back to the datastore, but this guarantees nothing. Of course I can see the use of a monotonically changing distributed counter. The reason I ask is for education purposes. Why did Google engineers bother to implement this functionality? There must be a good rationale I am not aware of.

[appengine-java] Re: Fwd: BlobstoreService not compatible with HTML5 multiple file upload?
Sorry to keep this thread alive but does anyone know of a work around for the HTML5 multi-file upload problem? To summarise HTML5 allows you to upload multiple files at the same time. Unfortunately on most browsers it gives all the files the same name. Therefore the app engine api MapString, BlobKey blobs = blobstoreService.getUploadedBlobs(req) only returns one blob key as all the others get overwritten due to the unique keys constraint of java.util.Map. For example is it possible to determine which blobs were uploaded by manually parsing the headers of HttpServletRequest? I wonder how blobstoreService.getUploadedBlobs(req) does it? I had a look and couldn't find anything obvious in the HttpServletRequest object that would allow me to link back to the blobs that were uploaded. I suppose I could add some nasty applet or flash upload tool to the page but I would rather not do that. Any ideas?

[appengine-java] Cheapest way to run an SQL EXISTS query with Datastore API?
What is the absolute cheapest way (CPU cost) theoretically to run an

I imagine FetchOptions would be
FetchOptions.Builder.withChunkSize(1).limit(1).prefetchSize(1) and
probably option 1 below.
Query query = new Query(KIND);
//add filters and sorts here, if querying by key use
query.setKeysOnly()
DatastoreService datastoreService =
DatastoreServiceFactory.getDatastoreService();
PreparedQuery pq = datastoreService.prepare(query);
//Option 1
long count =
pq.countEntities(FetchOptions.Builder.withChunkSize(1).limit(1).prefetchSize(1));
if (count == 0) {
//does not exist
}
else {
//exists
}
// or maybe
//Option 2
if (pq.asIterator().hasNext()) {
//exists
}
else {
//does not exist
}
Is there anything cheaper?

[appengine-java] BlobstoreService not compatible with HTML5 multiple file upload?
Dear All, I would like to upload multiple files to my Blobstore using HTML5's multiple file upload feature. input type=file multiple name=myfiles However, on Safari at least, I imagine each file that is uploaded will be attributed with the same name myfiles. Therefore MapString, BlobKey blobs = blobstoreService.getUploadedBlobs(req); does not work as Map keys must be unique so only one Map.Entry will be in the Map as the others will get overwritten. I can see on my dev server that all my files are actually uploaded to the Datastore. Is there a way around this? I guess either Safari hasn't implemented multiple of HTML5 properly or the BlobstoreService API needs to be changed to cater for the new HTML5 feature...

It might be nice for blobstoreService.getUploadedBlobs(req) to return a com.google.common.collect.MultimapString, BlobKey but it is probably too late to change that method of the API.

[appengine-java] TransformerFactory.newInstance() not working in App Engine SDK 1.2.8
Dear All,
I just migrated my code to App Engine SDK 1.2.8 and GWT SDK 2.0.0.
I have a method that converts an XML Document object into a string:
public static String getStringFromDocument(Document doc) throws
TransformerException {
DOMSource domSource = new DOMSource(doc);
StringWriter writer = new StringWriter();
StreamResult result = new StreamResult(writer);
TransformerFactory tf = TransformerFactory.newInstance();
Transformer transformer = tf.newTransformer();
transformer.transform(domSource, result);
return writer.toString();
}
Unfortunately I now get this error in the SDK:
javax.xml.transform.TransformerFactoryConfigurationError: Provider
org.apache.xalan.processor.TransformerFactoryImpl not found
at javax.xml.transform.TransformerFactory.newInstance
(TransformerFactory.java:108)
I do not get this error when I upload my app. Any idea what is going
on?
Best wishes,
Dan

[appengine-java] Discussion on will-it-play-in-app-engine
I have been trying to use Batik SVG Toolkit (http:// xmlgraphics.apache.org/batik/) to generate images on GAE with no luck. I get a ClassNotFoundError on org/w3c/dom/svg/SVGDocument. I have included ALL the Batik jars in my application but can't seem to locate which jar this class should be in. Your help would be greatly appreciated. It would be great to add Batik Status: COMPATIBLE to the list. Although it seems this project hasn't released anything in over 1.5 years.
