[appengine-java] JDO - simple update example
Datastore Group: I am spending way too much time trying to figure out how to perform a 'simple' update. I'm following the docs but nothing is working. When I get a no-record-found error I have to restart the appserver just to continue viewing the data using '_ah/admin'--which is _very_ disappointing. First of all, why is fist class error thrown when a query doesn't return a record? Second, why does a 'no-record-found- error' hang the entire server forcing a restart. Third, and most importantly, why is it not obvious how to perform a simple update of a single record? I'm using system generated keys, I can see the key value in the '_ah/admin' viewer, but I run into problems when I try to query the object/record using the system generated key value. I'm trying to use getObjectById(class-name.class, key-value); is this not the sanctioned method? It would be extremely appreciated if the documentation included a simple insert, update, select, delete example that everyone could copy and paste for immediate satisfaction instead of the deeper theoretical (and somewhat roundabout) form taken. I understand the documentation follows Datanucleus OEM product, but seriously, the appEngine docs should speak to this issue with greater brevity. I'm willing to do a write-up and post back to the list if someone can help me get started with basic CRUD. I feel it is a reasonable expectation that simple CRUD operations should CLEARLY be spelled out in the documentation available for 'quick' copy and paste.instant satisfaction. Also, a no-record-found error should not be an error, and it surely should not force a restart. I must be doing something wrong, I hope so, because I cannot imagine anyone working this way.

Re: [appengine-java] junit and local_db.bin
Hi Rommel with the method listAllDomain I can see the data, there should be
a problem with http://127.0.0.1:/_ah/admin/datastore perhaps a user roll
or something similar (in JUNIT or loggin with
http://127.0.0.1:/_ah/admin/datastore ?
Thanks.
2010/6/22 Ronmell Fuentes ringe...@gmail.com
Yup, for sure.
Let's suppose you have an entity called domain which has the following
attributes:
1. Key
2. Name
public void listAllDomain(){
List Domain results;
Query query=factory.newQuery(Domain.class);
try{
results=(ListDomain) query.execute();
if(results.iterator().hasNext()){
for(int k=0;kresults.size();k++){
Domain dumb=results.get(k);
System.out.println(Key:
\t+String.valueOf(dumb.getKey()).toString());
System.out.println(Domain
Name:\t+dumb.getDomainName());
}
}
else System.out.println(no results exist);
}
finally{query.closeAll();}
}
Where Domain.clas is the class type for your entity called Domain.
besides, in the query object you can set filters for your query.
this method will show the data in your data Store.
As I can see, if the local_db.bin is getting bigger each time JUnit is ran,
then the data must be there, so with this method you should be able to see
all the data stored in your Data Store. you have just replace all Domain
references for your Entity's.
Hope this is was helpful.

I think so, When I executed all is right, however I don't execute
teardown method because If I executed this the data are deleted.
Alsoeverytime I executed JUNIT the local_db.bin file is bigger than the
last
time so It has the data.

2010/6/22 Ronmell Fuentes ringe...@gmail.com
Hi Acerezo
remember the Data stored in dataStore is schemaless so, as far as I
know, only GAE knows how to deal with it.
When I want to see the data from the dataStore I use the classes
written in java in order to manage the data in Data Store.
in the other hand, you can use Restlets running on your app in order
to manage your data when deployed in GAE.
Rgds.

[appengine-java] Re: memcache best practice or framework
SimpleDS does also include a two-level Cache implementation. We are using the same approach of Hibernate: the first-level cache is bound to the current thread and will be discarded after the response is committed, and the second-level cache is relying on Memcache. The tricky part was dealing with partial cache results when invoking a multiple get(). Feel free to inspect the code to get your own ideas: http://code.google.com/p/simpleds/source/browse/#svn/trunk/src/main/java/org/simpleds/cache On Jun 18, 10:08 am, Toby toby.ro...@gmail.com wrote: Hello Ikai, Sorry but I might have worded my post incorrectly. I do not doubt memcache, in fact I use it very heavily and it is great. On Google I/O I learned that memcache is actually hosted on another machine and that for each request a significant network overhead is involved. In appstats I see about 20ms for a single request. Simple data-store requests are also between 20-50ms. So in fact memcache is good as second level cache but shows to be a bottleneck for data that I heavily use over and over again (plus it costs valuable API time). So the idea was to have some first level in-memory cache living on the same machine that is holding heavily used data to prevent the server round trip to the cache machine. Now you might tell me that my application is designed wrong. And indeed I could just put this in by myself. But as you also pointed out there are tricky parts like memory boundaries and other things to take care of. This is why I started this thread to see if someone has come up with a good solution. I think multiple cache layers are kind of a standard approach that has shown its usefulness in many places. It would be good to have that as part of GAE. Of course this is not the most urgent issue. Cheers, Toby On Jun 17, 6:46 pm, Ikai L (Google) ika...@google.com wrote: What aspect of Memcache is too slow? Have you run AppStats yet? The overhead of Memcache is low enough for many of the top sites on the internet to use. Some sites are listed on the main page here: http://memcached.org/ As you move closer and closer to local memory, the volatility of your cache will increase, so the only items I would store in local memory are items that are okay to lose. If you want, you can probably layer your application to fetch from memcache - fetch from authoritative source and place into local memory on a cache miss. Just be aware that there are process memory limits, and exceeding these will force a restart.

in java to show the data, does it work??
2010/6/22 Andrés Cerezo acerezoguil...@gmail.com
I think so, When I executed all is right, however I don't execute
teardown method because If I executed this the data are deleted.
Alsoeverytime I executed JUNIT the local_db.bin file is bigger than the
last
time so It has the data.
2010/6/22 Ronmell Fuentes ringe...@gmail.com
is your JUnit well configured??
2010/6/22 Andrés Cerezo acerezoguil...@gmail.com
But I can see the data created with the servlets with
http://localhost:/_ah/admin, but not when I the data are created
with junit.
2010/6/22 Ronmell Fuentes ringe...@gmail.com
Hi Acerezo
remember the Data stored in dataStore is schemaless so, as far as I
know, only GAE knows how to deal with it.
When I want to see the data from the dataStore I use the classes
written in java in order to manage the data in Data Store.
in the other hand, you can use Restlets running on your app in order
to manage your data when deployed in GAE.
Rgds.

Thanks.

Yup, for sure.
Let's suppose you have an entity called domain which has the
following
attributes:
1. Key
2. Name
public void listAllDomain(){
List Domain results;
Query query=factory.newQuery(Domain.class);
try{
results=(ListDomain) query.execute();
if(results.iterator().hasNext()){
for(int k=0;kresults.size();k++){
Domain dumb=results.get(k);
System.out.println(Key:
\t+String.valueOf(dumb.getKey()).toString());
System.out.println(Domain
Name:\t+dumb.getDomainName());
}
}
else System.out.println(no results exist);
}
finally{query.closeAll();}
}
Where Domain.clas is the class type for your entity called Domain.
besides, in the query object you can set filters for your query.
this method will show the data in your data Store.
As I can see, if the local_db.bin is getting bigger each time JUnit is
ran,
then the data must be there, so with this method you should be able to
see
all the data stored in your Data Store. you have just replace all
Domain
references for your Entity's.
Hope this is was helpful.

Re: [appengine-java] OneToMany mapping with JDO
If its an owned relationship, then if I'm not mistaken both classes (parent
and child) must have a Key class id, and cannot have a Long id, see this
excerpt from
docshttp://code.google.com/appengine/docs/java/datastore/relationships.html
:
The child class must have a key field whose type can contain the parent key
information: either a Key, or a Key value encoded as a string. See Creating
Data:
Keyshttp://code.google.com/appengine/docs/java/datastore/creatinggettinganddeletingdata.html#Keys
for
information on key field types.
Hope this helps,

Thanks Rajeev. I've raised http://code.google.com/p/googleappengine/issues/detail?id=3389 Setting the proxy properties did work.

It would be great if that could be fixed to.

You probably have struts configured to handle all requests. Wicket uses a filter rather than a servlet so it can pass unhandled URL's down the chain. Can you configure Struts like this?

[appengine-java] Re: Local Persistance of Data
Hello Ian , Hello John, Thanks for the response. @Ian : Yes, i m using the same URL but with my own port config ie http://localhost:/_ah/admin. I even tried http://localhost:/_ah/login but no output. I can see the local_db.bin file in my WEB-INF/appengine- generated/ directory. @ John, yep you are correct, all my request are mapped to be handle by struts. its by default '/' mapping.

Re: [google-appengine] Re: Is there any way to get around the Urlfetch 10 second deadline limit?
if it takes that much time for your server to respond your likely to fall
under the 30seconds limit.
if its a data that you need to receive back i suggest you alter the 2nd
servers code to call a url on the app engine once its complete with a dump
of the data. push and not pull.

I'm new to all of this, but doesn't the async method still have a

Now since the call goes to my server and then my server could take 15
seconds to run it's task and retuen a simple Data Added OK or Data

As I say, I'm very green so I may be missing the point completely, so

[google-appengine] Re: What is a pattern for keeping track of current users in google app engine?
I'm just giving a not-well-thought suggestion, but I'd rather use memcache for this. I guess something like using a time-dependent code as the key (i.e. a counter which increments every 30 seconds) and a list of user ids as the value, and simply doing a get() on the cache for the current counter value would work.

[google-appengine] Image Handler in Python
Dear All, I'm trying to handle pictures in my app. I'm trying to do it with the blobstore but I can't understand how it works. I just need to have a sidebar on the app where people can upload immagine and the app just shows thumbnails of these and clicking on it just links to the imagine page (old style, just a link to the imagine). Is there other solutions for this problem? Can I store the thumbs and the pics in a Expando DB? I can't understand if the blobs in the datastore are only long strings or picture too. But I suppose the the blobstore can store a lot more than a Expando DB. So I need just an handler to upload the picture (I can do this with the blobsotre, but I can't store) and a Handler to show them. Could someone show me the way? Please note, I'm not a programmer or a IT, this is just an hobby and I have no expertise in this matter.

[google-appengine] Re: What is a pattern for keeping track of current users in google app engine?
I wouldnt suggest Memcache for this purpose as memcache doesnt guarntee that what you put in it will be available after 30 seconds. Memcach can be flushed because of number of reasons. And memcache defnitely will not be scalable, if your number of ysers goes high then least used entries will be deleted automatically even if that entry comes under criteria of last 30 seconds. I think your first thought about using datastore is good enough. Why do you think Datastore will not be scalable? May be you can explain your problem statement bit more.

Alternatively, if you only want to see whether the user has polled, you could use the key 'user_%s_polled', substituting %s for the user's id, and place it in memcache with an expiration time of 30s. Every time you update the key, you can reset the expiration time. In Python, this would look like: memcache.set(user_%s_polled % user, True, time=30) Simply getting the key would tell you whether or not the user has polled in the last 30s. Memcache would then handle expiration; after 30s, the key is removed for you.

If you know an entity's key, there's no need to do a query at all; you can simply get the entity (using the low level Java API, as you seem to be, I believe you want DatastoreService.get(key) ).

Re: [google-appengine] Re: What is a pattern for keeping track of current users in google app engine?
I'm guessing it wont be scalable because if I have 1000+ polling users, I would have to query and fetch that many entries every time my task runs every second or so. Maybe that's not so bad?

I use appcfg.py script's upload_data functionality to upload backups to my test app. The app is written in Java, but I don't think it matters. I create backups using download_data script. Here's the problem: I have 124 entries of the specific kind in my datastore. All of them are downloaded and saved in a CSV file, so it's 124 lines. When I run upload_data script, it reports that all 124 entries were uploaded. But when I check them in a datastore viewer, only 83-103 of them are there. This effect is 100% reproducible. I then delete the temporary database file and re-run the upload (leaving the already uploaded entries in the datastore), and it progresses a bit, to like 110 entries. Then about 115, 118, and from then on it gets less and less per iteration: 120, 122, 123, 123, 124. So finally all of them appear there but it takes a lot of time and slows drastically in the end. I saw some people mentioning the similar problem (not all of the entries being uploaded) in the Web but their problems had something to do with a patch which I don't use.

Re: [google-appengine] Re: What is a pattern for keeping track of current users in google app engine?
The key for the pole would be made as follows second = #get the min interval of the current time if second29 second=second-30 #this gives us 0-29 and then 0-29 again for one min then make the mcache key as key='pole'+second I don't know how many users may pole in one second - but i cant see merging a list stored in each pole would be too much of a handful. If 30 poles are too many use 15 - 1 for each 2 second element or 3 Further more i don't know what info you need on the user - if all you want is their identifier - that can be stored in the list or their email this would save on needing to get the users data from the model using the key.

[google-appengine] Re: What is a pattern for keeping track of current users in google app engine?
I have more then 1000 users online at peak and I'm using datastore for this. Unfortunately, updating last online time costs quite a lot of CPU time. And I'm updating only once per 5 minutes (on each poll I write last online time to memcache and put it into datastore via cron).

I need to keep a list of the users that have polled in the last 30 seconds handy for a task I have queued to run every few seconds. The obvious way I see to do it is to update a datastore entry every time the user polls, and query the entries that have a timestamp within the last N seconds within my task queue. I can't imagine this scaling well. Any recommendations? Thanks. -- You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] How to speed up the task queue execution?
Back to my initial question... ;-) @djidjadji: Thanks for your post! Do you know more about this 1 second limitiaon? I'm working only on separate entity groups (but they are of the same kind) only. I've been in that talk at the Google IO but I'm still confused why I'm not able to execute more than ~2 tasks per second. Is there some global transaction/s limit per app? Or is the problem just that my app has low traffic for a long time and then I'm starting ~1500 concurrent tasks? But doing this for some time, I do not get any warnings about new allocated nodes, but it is still not getting faster.

Re: [google-appengine] How to speed up the task queue execution?
It's not a 1 second limitation. But if you hammer with concurrent transactions on a single entity group you get a lot of collisions and retries and that slows the whole process down. A rule of thumb is don't try to update a single entity group more then once a second for a long period of time. It's not about the kind but the individual instances of a kind. If you have 50 request/s and they all want to update 50 different objects with transactions it should work. It might slow down a bit if they all hit the same tablet server but you won't have collisions The example at the TaskQueue man page also mentions the 1/s update by transaction. 2010/6/24 dflorey daniel.flo...@gmail.com: Back to my initial question... ;-) @djidjadji: Thanks for your post!

[google-appengine] What is a pattern for keeping track of current users in google app engine?
I don't know if the solution allows a user to pole more than once in 30 seconds and i don't know if in fact you need to know if someone has polled multiple times in 30 seconds or keep an audit of all the historical poles - these questions would all change how this could and should be done. If you may have upto 1000 users polling in one 30 second segment then you would have a list of 33 user refs in a list stored in each pole. I also dont know what information must be stored when they pole - if you need time and user ref or just a ref or if in fact you need more information. mcache may loose data - though i am surprised some are saying this could happen in this scenario - so again i don't know how accurate this must be and if in fact a pole was lost from time time whether that would be a problem especially if of course the same users are polling continually and being added to other poles. speed over accuracy? Your first suggestion of using a model is still a good one tho 1000 entities being read every n seconds is hefty in my opinion. especially if you need to read user data from db and not just get the key. In the pole scenario a dictionary could be used and when the user poles their data read and stored in the pole in mcache at the time of polling as i have documented, which would save re-loading data from db when your task runs. That said in addition to my last post with the mcache 30 pole solution - a bug fix is below for working the pole no 1-30 i did mention i ran out of time on this method. The key for the pole would be made as follows second = #get the min interval of the current time from server if second29 second=second-30 #this gives us 0-29 and then 0-29 again for one min then make the mcache key as key='poles%' %(second) If 30 poles are too many use 15 - one for each 2 second element or 10 one for each 3 second element - again their are accuracy concerns here 30 being the more accurate this would be down to what you need from this routine. If you have a need for the user data stored in the list - their is no need to merge it? just load each pole and iterate it doing whatever function you need to pursue? Their is no reason to merge the 30 poles for what reason? Thats just making extra work. This is the only obvious way i can see of using mcache to perform such a task - in comparison to using a model and fetching entities with a time zone.

[google-appengine] Re: TemplateDoesNotExist: css/datastore.css
I'm using Django 1.0, so it may be that your advice doesn't apply to me. In case it does, I tried following what you're saying. Unfortunately, I'm find it quite difficult to understand what you think the problem is. I get your point about how there's some config in settings.py that sets what template loaders to use. I think what you're saying is that some other file is clobbering that setting. Specifically, you seem to be saying that if the following line exists in one of my files, I'll get sporadic TemplateDoesNotExist errors: from google.appeninge.ext.webapp import template I did a grep on my project, and I don't have that line anywhere. On May 17, 1:13 pm, Roger Hu roger...@gmail.com wrote: This import is causing massive headaches on App Engine deployments with TemplateDoesNotExist sporadic messages. Assuming you have Django 1.1 setup correctly, the global_settings.py file will setup TEMPLATE_LOADERS to load from both the project dir (/templates) as well as any INSTALLED_APPS dir. But we noticed sporadic issues with App Engine reporting the issue: TemplateDoesNotExist: Tried [u'/base/data/home/apps/ myapp1234/1-2-2-8.341999523263263665/templates/volunteer-11.html'] The reason? By default, Django has these two TEMPLATE_LOADERS defined in its global settings (defined in conf/global_settings.py): TEMPLATE_LOADERS = ( 'django.template.loaders.filesystem.load_template_source', 'django.template.loaders.app_directories.load_template_source', ) The second line tells Django to try all the INSTALLED_APPS dirs whenever attempting to render an HTML template. For instance, we do not need to specify volunteer-11.html because it will try to look inside ragendja/templates, accounts/templates, and civio/templates, in the order defined by INSTALLED_APPS inside settings.py: INSTALLED_APPS = ( 'django.contrib.auth', 'django.contrib.sessions', 'django.contrib.admin', 'ragendja', 'accounts', 'civio' ) If you accidentally import this line in your Python code, from google.appengine.ext.webapp import template The GAE reconfigures TEMPLATE_LOADERS inside google.appengine.ext.webapp.template: import django.conf try: django.conf.settings.configure( DEBUG=False, TEMPLATE_DEBUG=False, TEMPLATE_LOADERS=( 'django.template.loaders.filesystem.load_template_source', ), ) +#from google.appengine.ext.webapp import template The result is TemplateDoesNotExist messages that may or may not occur. 3. If you are using Django 1.1, you must be careful that you're not importing google.appengine.ext.webapp import template. The solution, I believe, is to simply remove all webapp dependency imports: perl -pi.bak -e s/^from google\.appengine\.ext\.webapp(.*)/#from google.appengine.ext.webapp\1/g *.py We're still confirming that these changes will resolve the issue, but it seems to explain the problem we have been having on Django 1.1.

When I updated to django 1.1 I get TemplateSyntaxError: Template u'../index.html' cannot be extended, because it doesn't exist.

[google-appengine] Cleanest way to start a looping task?
I have a task that resubmits itself, so that it loops over and over indefinitely. Every time I start dev_appserver.py, I have to open this url to get it going: http:///localhost:8080/loop?key=0. Is there some automated way to do this so that it starts when I run dev_appserver.py, or when my app gets uploaded? While I am on the topic of tasks, is there some way to automatically execute the task queue built into dev_appserver? The documentation seems to say I must do it manually, but I hear whispers that the java guys can automate it. I found a script to do it, but it's a pain to run every time I start things up again.

[google-appengine] Entity Groups - does write time increase as # of objects in entity group increase?
Hi,
I've created two simple classes which I want to use in an entity
group:
class User {
int numReports;
}
class Report {
}
the User object will always be the parent, Report instances are part
of a User's entity group. There can be many Report objects per User:
User
|--- Report
when I save a Report instance, I want to increment the 'numReports'
counter in the User object, in a transaction. This arrangement works
fine.
But as the # of Report instances increase, does app engine have to
lock all other Report instances in the same entity group before
performing the transaction? I'm worried that performance will degrade
as the # of Report objects per User increases.
Thanks

[google-appengine] Typical monthly costs for running an app
A previous thread morphed into a discussion about running costs and then then morphed back again. http://groups.google.com/group/google-appengine/browse_thread/thread/d92d127220fe4671/d12ed358b3fdaac9#d12ed358b3fdaac9 There were a lot of attempts to calculate theoretical costs, but no real-world examples. My app generally handles between 1 and 2 requests a second for most of the day. It currently attracts about 2000 unique users a day, who browse through 6 generated pages each (including multiple gets and puts, and at least one email sent). I have billing enabled, but have only ever paid a few cents a day for email - I don't get anywhere near my other free quotas. All this consumes about 0.6 cpu seconds a day, 300MB of bandwidth, and 200MB of storage. So from my perspective, the figures bandied about in the thread above above seem crazy.

Re: [google-appengine] Typical monthly costs for running an app
Well what can i say that is just brilliant! - you should be over the moon. This is why i congratulate Google on building a superb platform and a brilliant inventors notepad for creating applications and scaling them at a cost we can afford all to realize our dreams. Where can you get such fantastic technology like this for that price. I only hope they continue their efforts in moving it forward and continue to keep it's pricing so that we can all invest our precious time without having to outlay money we don't have to make applications a reality before they start making money. As i said well done Google. I think your example is a good one. I must say i have spent 6 months solid learning GAE and i have thoroughly enjoyed it. It is a well earned rest from wasting too much time with other known technologies that make you invest too much into configuration, deployment and into the decision making of which one of their dam technologies to use next. i think we know who i mean.
