[appengine-java] Doubt about Datastore (Python/JDO/Low level api)

2011-03-10 Thread coder
I was seeing this test http://gaejava.appspot.com/
and i have seen that crud operations in python are faster than in jdo
and that in low-level api is faster than in jdo.
So, i am tempted to leave java implementation for my google app engine
apps and to use python.

Or is there a way to create apps that are as fast as apps created in
python?

What do you think about this?

2011-03-10 Thread Didier Durand
Hi,

You should give a try to packages like Objectify (recommended by
Google also: they tend to push people away from JDO / JPA...)

It is simpler to learn than JDO and much more efficient in terms or
performance.

I abandonned JDO for Objectify many months ago and I am extremely
happy about that decision

So, give it a try

[appengine-java] Using BulkUpload into Local Java Dev Server on Mac

2011-03-10 Thread Brian Conneen
I've seen a bunch of threads on this issue, but there doesn't seem to
be a definitive example of getting this to work.

Essentially I want to migrate my existing Python app to Java, and I
know I can deploy both versions into production. But I want to do lots
of testing locally before ever deploying a Java version.  And in order
to test, I need to upload my data into my local Java dev server
datastore.

I can use bulkuploader to export the datastore from the production
PYTHON app and load it into a local PYTHON dev server datastore no
problem. I've done it hundreds of time.

If I try to use the same export to load into my local JAVA dev server
datastore, I always get an AuthenticationException [See stack below].
Yes I've configured remote_api. Yes I can access 
http://localhost:/remote_api
from a browser. It first takes me to the authentication page.  But
bulkupload just won't work against my local JAVA dev datastore.

I've now read every thread on this subject, and it seems like there
might be a commonality.  Perhaps everyone running into this
AuthenticationException is running on a Mac? I really don't know
what's causing it, and I can't believe more people don't want to do
the same thing.

[appengine-java] Can I set GAE's dev_appserver to automatically reload context when I change .class files?

2011-03-10 Thread Luca Matteis
Hello everybody!

I'm using Google AppEngine with their built in web server. My
development goes about in a simple way: I make changes to my .java
sources or .jsp and compile using ant and to see the changes I have to
restart the development server.

I'm wondering if there's a way I can avoid this last step of
restarting my development server - somehow refresh the cached classes
context of my web-server. The options provided by Google on this dev
server are quite limited and am wondering if there's a better way.

I would like to avoid using something like JRebel which I could buy,
but for this simple project I'm just wondering if I can remove the
burden of restarting my web-server... otherwise I'll live with it.

Thanks.

Luca

Me too (on a Mac after the update to JSE 6b24). Funny, it doesn't
happen all the time. I have more luck when I run the server under the
debugger. After that it will sometimes start to work without
debugging.

I notice this in the console, but I can't remember if it was there
before:

2011-03-10 11:34:13.397 java[628:903] [Java CocoaComponent
compatibility mode]: Enabled
2011-03-10 11:34:13.399 java[628:903] [Java CocoaComponent

Probably not related, but the process does seem to terminate after a
timeout (error 139).

[appengine-java] Re: GregorianCalendar source packages

2011-03-10 Thread Damien Dessagne


I ran into the same problem earlier today, and had to search for quite a 
long time to understand where the problem came from.
The problem comes only from GWT and is not related to AppEngine (obviously, 
this topic shouldn't be in the GAE/J GoogleGroup, but anyway ... ^^).
GWT emulates the JRE on the client-side, but not all classes are supported. 
Have a look at the GWT Documentation  Reference  JRE Emulation Reference 
section for more details on what is currently supported and what is not.

At the moment, the java.util.Calendar classes aren't supported 
(http://code.google.com/intl/fr-FR/webtoolkit/doc/latest/RefJreEmulation.html#Package_java_util),
 
but you can use the com.google.gwt.user.datepicker.client.CalendarUtil class 
to perform simple calculations though.

Hope this helps.

[appengine-java] Weird performance problem last 3 days or so

2011-03-10 Thread mdt
For the last couple of days our app performance has tanked, with requests 
that used to take a second or so taking up to 30 seconds. Since we've made 
minor changes that probably aren't the cause something gave me the idea 
of deploying the same code under a separate name, and comparing the two. 
That is, let's say we have foo.appspot.com normally, I deployed the SAME 
code as bar.appspot.com. 

The foo deployment crawls, and the bar deployment is fine. 

So it's as if the production app name has gotten messed up somehow. (Yes, I 
also tried yet another new deployment under the old app name). The two 
deployments, AFAIK, differ only in that the production version is linked to 
a custom domain name, but I've reproduced this problem using the appspot.com 
domain only, so it's clearly not a DNS problem (also, I see the really long 
latencies in the appengine logs).

We've been using app engine for Java successful for this app for six months, 
so we're not complete novices, but could still be doing something dumb. 

Any ideas how to diagnose this? Any help appreciated: this is threatening a 
venture that was just barely getting off the ground.

Oh, I thought of deleting the app and recreating, but I'm afraid I'll have 
trouble recreating it and then have to go messing with DNS mapping.

Thanks in advance!

[appengine-java] Re: Weird performance problem last 3 days or so

2011-03-10 Thread Jay Young
Might the difference between your foo and bar deployments be the size of the 
data set you have for each app?  If the fresh install is consistently fine 
and the old one is consistently slow, maybe you've hit a threshold where 
some inefficiency in your queries or data handling has started to actually 
matter.

Actually, I overstated things. The app actually now uses persistence VERY 
LITTLE, and only on one page. But the persistent store on the second 
deployment is empty. It would be strange if this was the problem, but it 
could be.

 section for more details on what is currently supported and what is not.

 At the moment, the java.util.Calendar classes aren't supported
 (http://code.google.com/intl/fr-FR/webtoolkit/doc/latest/RefJreEmulati...),
 but you can use the com.google.gwt.user.datepicker.client.CalendarUtil class
 to perform simple calculations though.

 Hope this helps.

[appengine-java] Re: Can I set GAE's dev_appserver to automatically reload context when I change .class files?

2011-03-10 Thread iein valdez
I have the same issue as you do. I decided to go with JRebel and it
works great with App Engine. I've been using it for months and it's
saved me a ton of time. IMHO worth the money.

 Hello everybody!

 I'm using Google AppEngine with their built in web server. My
 development goes about in a simple way: I make changes to my .java
 sources or .jsp and compile using ant and to see the changes I have to
 restart the development server.

 I'm wondering if there's a way I can avoid this last step of
 restarting my development server - somehow refresh the cached classes
 context of my web-server. The options provided by Google on this dev
 server are quite limited and am wondering if there's a better way.

 I would like to avoid using something like JRebel which I could buy,
 but for this simple project I'm just wondering if I can remove the
 burden of restarting my web-server... otherwise I'll live with it.

 Thanks.

[google-appengine] if I have a property for my model that I don't set, is there a cost to index it?

2011-03-10 Thread Joops
Hello all,

I am developing an app using the Python SDK and I would like to have a
deleted Date property on my model, (which for most items will be
unset).
This will be set when an item is deleted.

I am not using expando models.

Please could someone confirm if my thinking is correct

If I create a new instance and Put() it, it will not have to create an
index record for that column (as there is no value)

If I update an instance with a deletedDate and put() it, then it will
create the index record (and further updates to it will require
updating the index).

If I set it to None, then it will be indexed and there will be a cost
for future updates.

Thanks very much

J
ps. I am asking, as I want to ensure that adding and updating are as
cheap as possible

[google-appengine] Re: Deleting Data Really Expensive!

2011-03-10 Thread Jason Collins
We are also finding that deletion is an expensive prospect. So much so
that we find ourselves discussing the cost-tradeoff of simply leaving
the dead data around because the storage cost is so much lower than
what it would take to delete - even using the techniques mentioned in
this post.

It hurts me to think that we're leaving disks spinning with junk on
them.

Google, any improvements on this front that would lead to less
datastore CPU usage for deletions?

[google-appengine] Re: Deleting Data Really Expensive!

2011-03-10 Thread nickmilon
I also think deleting data is quite cpu intensive and expensive
process, different techniques described above by Tim, Wesley, Ikai and
others give only marginal benefits.
There are some use cases where we deal with ephemeral data and all
entities of a model are obsolete-irrelevant after some time.
There must be a way to wipe out a  model without having to delete all
individual entities.

Happy coding ;-)

[google-appengine] Re: Problems copying entities to the high replication datastore.

2011-03-10 Thread Francois Masurel
I had this problem on about 1% on my child entities containing binary data.

Hopefully, I didn't have too much data in my MS datastore, so I could 
recreate them manually.

[google-appengine] Re: Problems copying entities to the high replication datastore.

2011-03-10 Thread Petey
It does seem like it copied over some child entities so that isn't the
exact issue.
The main problem I have is that not everything gets copied. For
example, I have one entity kind that only got 730,000 entities copied
when the source app has 810,000 entities. I don't know how I would
find the missing ones and just copy those over. I also am afraid to
try it again because I don't want to get charged another $80.

  It looks like this happens to all child entities in an entity group. I

  Does anyone have any workarounds? I really need this to work. I've
  noticed several other people have had this issue, but they also have
  gotten no response.

[google-appengine] PyCrypto and user passwords.

PyCrypto offers the blowfish cipher, but not the bcrypt hash.

What's the best way to store passwords on App Engine with PyCrypto?

Thanks,

[google-appengine] Re: Where can I find commercial successfully websites created using GAE?

2011-03-10 Thread vlad
Just launched recently (not a commercial success yet) a free multi player 
poker site http://www.zodiacholdem.com. Built completely on appengine using 
python SDK.
I am pretty happy with the platform. Aside from stability the only gripe I 
have: It is pretty hard to build server driven workflows due to taskqueue 
unpredictable timing. This is really a key feature which in my mind enables 
a bunch of new interactive applications. Whenever user interaction is 
involved like in my case it is poker play among real people, not bots, so 
you need somewhat bounded timing from firing tasks.

Re: [google-appengine] App Engine TOS question

Hi Jeff,

Functional separation of the kind you describe is fine, and in compliance
with the TOS.

On Wed, Mar 9, 2011 at 1:03 PM, Jeff Knox lairdk...@gmail.com wrote:

 I am trying to serve two different sub domains (www.domain.com and
 app.domain.com).

 The www domain is the primary web site. This will initially be basic html
 and/or jsp pages. As it evolves there may be some simple servlets driving
 it.

 The app domain is the main application I'm developing (and currently my
 primary focus). It is a standalone application but there will be links
 between the two sites (www  app).

 My question is - Can I create two App Engine projects to support the sub
 domains? I understand that using multiple apps to spread out the quotas is
 not allowed. In this case I'm simply trying to divide up the functional
 units between the app and the web site.

 In the future there will likely be more than one application/project. Each
 of these will be linked from the www domain. In this case it makes even less
 sense for the sub domains to be combined as they will be unrelated apps.

 So I guess what I'm asking is if it is OK to create an app strictly for my
 WWW domain with links to my APP domain?

 Thanks

Re: [google-appengine] Apps and Accounts

2011-03-10 Thread Nick Johnson (Google)
Hi,

Applications are not 'tied' to domains unless you are using App Engine for
Business. Standard App Engine apps always have a presence on appspot.com;
other domains can then be mapped to them.

 Scenario:

 I develop an application under mydomain.com
 Share the application to someone at theirdomain.com
 Promote that person to be an owner of the application
 One year later mydomain.com goes away.

 Does the person at theirdomain.com still have full access to the app or is
 it permanently tied to the original creator and, thus, will it be deleted
 from App Engine?

 Thanks
