[appengine-java] Hosting Java application

2011-03-08 Thread foxyripper
Hello everyone,
Sorry for the stupid noob question. I'm creating a Java Application that use 
several libraries and basically gets streams from twitter and somehow use 
them to save jpg images. I wonder if Google App Engine is what I need to 
keep my application running without need to run it on my computer 
permanently. And is it possible to do that at all?
Thank you in advance guys

[appengine-java] Re: uploading 100k lines into the datastore is enough to max out the CPU time?

2011-03-08 Thread Didier Durand
Hi,

What captain says is true: you should remove your make persistent for
each iteration and replace it with a makePersistentAll()  every N
iterations: that will batch the writes and make them more efficient.
(but don't wait to have too many of have: I'd start with approx 100
and see if I can increase this number)

Beside that, I must admin that your code looks pretty standard...

Question: do you use the regular DS or the new Hgih Replication DS ?
HR DS is supposed to be slower for writes.

Let's see the result of this change

regards

didier

 Hi Claudio

 Try makePersistentAll()

 It will certainly help

I'm not sure if it's a red herring or not (currently assuming it is)
but I also see the following in the console when I try to upload:

And thirdly - I have noted that on occasion I get an error 500
internal server error when trying to connect to the GAE console
(https://appengine.google.com) - could this be something to do with
the issue I'm seeing?

I'm using app engine SDK version 1.4.2 and my upload command is as
follows:

Hopefully I've provided all the necessary information here, I realise
that there are plenty of 403 related posts out there but none of them
seemed to answer my specific issue hence posting this one.

Any one got any ideas what could be going wrong here?

Re: [appengine-java] Re: uploading 100k lines into the datastore is enough to max out the CPU time?

2011-03-08 Thread Stephen Johnson
Hi Claudio,
You have 12 total fields all of which you have indexed which is the default.
You have 1 key field and 11 non-key fields. This will result in 23 index
entries being written for each entity. You get 1 ascending index on the key
field and by default you get both an ascending and descending index on the
other 11 non-key fields. This will take A LOT of CPU for each entity. Do you
need them all indexed? If not, I would set them to unindexed. That should
help a lot.

Re: [appengine-java] Re: uploading 100k lines into the datastore is enough to max out the CPU time?

2011-03-08 Thread Cláudio Coelho
Hi,
I thought about taking out some indexes, but I can only take out 3 of them 
and I don't notice a big difference in the results.
However, the method persistentAll (quite logical actually!) did make a huge 
difference. It basically cut the time and cpu load to one 3rd. I'll probably 
be able to bring it down a bit more with some tweaking.

These 100k lines are to be inserted just on setting up the app, everything 
else is supposed to grow much slower and my app probably will have a 100:1 
read to write, so I guess I'm not too worried. I'm new to GAE and I was just 
a bit surprised to just how careful you have to be to minimize the cpu load.

Thanks everybody,

Cheers

Re: [appengine-java] Sub domain for static content

2011-03-08 Thread Jeff Knox
So I'm still trying to sort this out.

If I created a second app to serve the WWW web site would that be a 
violation of the App Engine TOS? While the two pieces are related they 
aren't the same.

The WWW mapping would be more of a traditional web site that would most 
likely grow and potentially include back end services like a blog and such. 
The PHOTOGRAPHY mapping is strictly the photo album and image services. (In 
the future there are other applications I would like to build but they won't 
be tied to the same domain name as these two are.)

I'm not trying to circumvent any quotas - just attempting to configure it 
all in the most logical/efficient way.

Thanks

[appengine-java] Hanging request after app deployment (no log entry)

2011-03-08 Thread John
I'm seeing a behavior that I hadn't observed before. After one of my apps is 
deployed, the first request hangs for a LONG time (I haven't left it sitting 
for more than 10 minutes yet, so I don't know how long). There is no GAE log 
entry corresponding to the hanging request. I don't have much to provide for 
an issue report. Figured I'd first ask whether anyone else has encountered 
something like that.

Offhand, I don't think this would be possible as you would be at least
creating a new .class file.
GAE allows no File I/O.

As others have pointed out the file I/O issue precludes using a

The best I can suggest is using BCEL to construct classes at
runtime... But I have never tried this with GAE so I do not know if
BCEL is whitelist safe.

Just as a followup you need to take a look at the BCEL API to see if

 Sorry for the stupid noob question. I'm creating a Java Application that use
 several libraries and basically gets streams from twitter and somehow use
 them to save jpg images. I wonder if Google App Engine is what I need to
 keep my application running without need to run it on my computer
 permanently. And is it possible to do that at all?

the only out bound connections available on appengine are http.
so if twitter supports http, all good.

saving images no problem

2011-03-08 Thread Jay Young
I dunno about this.  The different JVM language runtimes (JRuby, Rhino, 
Groovy, etc) all generate and run bytecode on the fly.  I don't know if you 
can cache that generated byte code and re-execute it later, though that 
seems like it'd be a shortcoming of the interpreter, not the App Engine 
environment.

[appengine-java] Development AppEngine server quits with no warnings.

2011-03-08 Thread RoyR
Hi

I started having a strange issue today (nothing changed, except for a Mac 
automatic system update).

As soon as start the AppEngine server, it comes up, and then just quits 
without any warning or errors. The listener stops listening on port , 
and the JVM just exits. Same thing happens in Eclipse as well as 
command-line.

Famous last messages... (running the default vanilla guestbook basic app)

Anyone know what could be going wrong here, or how to get more details on

I tried deleting the workspace and creating from scratch, as well as 
uninstalling and reinstalling GAE, GWT and the Eclipse plugin, but no use.

[appengine-java] Re: BlobstoreService, No image data is available.

2011-03-08 Thread Timothy Wilson
A solution 2 years later, but here is how I just solved this.

First, create the image from the blobkey

Crop that image with 0,0, 1, 1... Crop uses normalized coordinates.

The resultant image out of that applyTransform is the 'original' image, but 
it now has width/height all other image info.

The blob store does seem half-baked, its hard to store data, and these half 
implemented API calls are minefields.

then to add new one. 'There can be only one' :D I tried unsuccessfully to

disable old GAE app from Google Apps. We can have more GAE apps registered 
to Google Apps. 

Actually very nice and now so very logically.

Re: [google-appengine] HR datastore batch put

2011-03-08 Thread Matija
Hi Robert,
if you think of batch put as simple code helper for multiple entity put 
statement everything is pretty clear. 

But because latency for single and batch put is almost same batch put is not 
simple code helper. I don't ask for some kind of multiple entity group 
serialization isolation level. I ask if HR datastore batch put has atomicity 
guarantee or not. 

After every successful put statement I am able to get entity key for every 
stored entities but I don't need this information very often. I think that 
it would be nice to have in any kind of async/no response way that they can 
provide atomic batch put statement. I think that this paxos/transactional 
log replication/'jada jada' arhitecture provides means for this very 
interesting database concept. Or maybe I am wrong. So wrong :D

Thanks for the suggestion, Robert.

The problem is, under normal conditions, the catch blocks do get
executed. I've seen ApplicationError, db.Timeout and even
DeadlineExceededError get caught. But during this kind of error
spikes, I don't see the same piece of code get a chance to run.

 Yeah, I saw some several pretty serious spikes in the error rate
 earlier today too (several large spikes between 3 and 9 hours ago).

 It sounds like perhaps your try-catch is not wrapping the correct
 statements, or it is not catching the correct errors.

 For timeout related issues, I usually catch:
   apiproxy_errors.DeadlineExceededError,
   db.Timeout,
   apiproxy_errors.ApplicationError (check for application_error in 2, 5).

 The worst thing is, the except statements of our app rarely get executed
 during the occasions, therefore we don't get a chance to recover.

 I guess we are just a very ordinary site, about 3QPS on average. If I knew
 this kind of 'down time' rate on GAE before hand, I would definitely
 reconsider adopting the platform.

 With hopes,

 Thanks for the suggestion, Robert.

 The problem is, under normal conditions, the catch blocks do get
 executed. I've seen ApplicationError, db.Timeout and even
 DeadlineExceededError get caught. But during this kind of error
 spikes, I don't see the same piece of code get a chance to run.


Try this:

  
http://code.google.com/appengine/docs/python/config/appconfig.html#Custom_Error_Responses

specifically, the 'timeout' error handler.

Your exception handler wont run if none of your code is run if, for
example, there was a timeout in the google infrastructure before an
instance could be allocated to run your code.

[google-appengine] Cannot import name util

2011-03-08 Thread Tomas Rampas
Hello all,
I'm using Python, and Django 1.2 and currently I'm facing problem with 500 
App server error with following log entry:
type 'exceptions.ImportError': cannot import name util Traceback (most 
recent call last): File /base/data/home/apps/jdiakup/1.348854888698905944/

I have only one place where mentioned *util *module is referenced:

*from *google.appengine.ext.webapp *import *util

Does anyone have any idea why this is suddenly happening?

Thanks 

Tomas

So don't bother trying that as a workaround, because it doesn't help.

[google-appengine] Error in importing blobstore

2011-03-08 Thread jay
Hi 

An application that has been running fine .. is suddenly giving me a server 
500 error.
No change has been made to the application. When I look at the logs - it is 
pointing to
a line which is importing the blobstore.

from google.appengine.ext import blobstore

1) Can you please tell me what is happening to my app? 
http://rzoozx.appspot.com?
2) Is this related to a runtime issue that is being worked on now? or Is 
this my problem?

Thanks

It would be interesting if there was an AppEngine app whose sole purpose was
to provide a simple API that used your earlier gist to provide a moving
average of clock-skew within AppEngine.

It could also plot the collected time series as a quick visual guide to time
in the AppEngine domain.

Anyone interested in co-developing such an app?

 - A regex with the path of the affected request.

I've been looking for a known issue, but I had no luck. Should I open

Re: [google-appengine] Searching logs in log viewer fails

I've experience this as well.
a similar issue happens when you just use next several times. the log would 
'end' at random times.

Re: [google-appengine] Re: Massive DeadlineExceededError - MS datastore

2011-03-08 Thread Will
Thanks for the link, Stephen.

In my case, the code do get executed, they fail on datastore put(), mostly
due to DEE, timeout, ApplicationError. In normal circumstances, the failure
is rare and it gets caught by catch blocks, nicely. However, sometimes
during a short time frame, there are sudden bursts of this kind of errors,
and when that happens, the catch blocks never get a chance to run, according
to our logs.

Best,

Will

 Try this:


 http://code.google.com/appengine/docs/python/config/appconfig.html#Custom_Error_Responses

 specifically, the 'timeout' error handler.

 Your exception handler wont run if none of your code is run if, for
 example, there was a timeout in the google infrastructure before an
 instance could be allocated to run your code.

-Manual Verification of Potential Vulnerabilities
-Modification of Requests to the Application

The appID is ovb-dev

We will responsibly alert you to any vulnerabilities we may uncover.

Re: [google-appengine] High Replication and Blob storage price

2011-03-08 Thread Alfred Fuller
Blobstore is still $0.15 G / month when using the HR datastore. Only the
datastore storage price is different.

On Sat, Mar 5, 2011 at 8:53 AM, Peter Liu tinyee...@gmail.com wrote:

 Hi all,

 http://code.google.com/appengine/docs/billing.html

 In the doc it says HR cost is $0.45 G/month. Does it include the blob
 store storage? or the storage by blob store remains at $0.15? It's not
 clear on the doc and from the admin page I always see total storage
 that's datastore + blobstore.

 I can understand that HR mode charge more for data stored in bigtable,
 but blob store data is a different kind of storage right?

 Say an app has 1G of user data and 10G of images stored in blobstore.
 The images are served statically and can never be changed. In this
 case really don't see (and need) the benefit of HR in serving the
 images.

 If the 3x cost only applies to datastore, it makes much more sense to
 switch.

 Thanks.

[google-appengine] Request CPU variance with 'Always-on'

2011-03-08 Thread lp
hi all,

i have getting large variance in my request and api cpu on a java app.

I have read the countless articles on the topic and the quota doc.

what i am seeing is *not* do to process startup as i have 'Always on'
enabled since there is no more of the ' This request required a
process to startup.

Below are a sample of the logs for the same query within 15 minutes.

what is going on is my app really written that dodgy?
the same query is being executed each time but the results have an
enormous variance on the elapsed time and request cpu.

I have profiled my code and i can see where the variations are
happening but it is in JPA calls like em.find, em.merge which are
fairly basic stuff.

Q1.what is causing this variance... my code or appengine accounting?

any help is most welcome.

Re: [google-appengine] HR datastore batch put

2011-03-08 Thread Robert Kluin
Hi Matija,
  The batch-put gets 'parallelized,' that is part of the reason I do
not think the put (across multiple entity groups) will be able to be
atomic;  I don't think you'll be able to figure out which entities did
or did not get written if you get an exception.  Unless, of course,
the app engine datastore guys are working on cross-entity group nested
transactions.  Of course, then you would probably lose some of the
performance benefits of the batch put being parallelized.

 Hi Robert,
 if you think of batch put as simple code helper for multiple entity put
 statement everything is pretty clear.
 But because latency for single and batch put is almost same batch put is not
 simple code helper. I don't ask for some kind of multiple entity group
 serialization isolation level. I ask if HR datastore batch put has atomicity
 guarantee or not.
 After every successful put statement I am able to get entity key for every
 stored entities but I don't need this information very often. I think that
 it would be nice to have in any kind of async/no response way that they can
 provide atomic batch put statement. I think that this paxos/transactional
 log replication/'jada jada' arhitecture provides means for this very
 interesting database concept. Or maybe I am wrong. So wrong :D

[google-appengine] documentation improvements

2011-03-08 Thread Brian Lim
I don't want to write much about documentation improvement suggestions
so I will post briefly what kind of improvements could be made in many
places.

People like specifics so just to pick one page at random:

http://code.google.com/appengine/docs/java/datastore/hr/

This page is pretty short so there is not a lot wrong with it but the
fact that a short page can have problems is remarkable enough for me
to comment on it.  There are some obvious problems.  I guess this
could be the end of this comment  but to make it more
obvious, there is some information repeated across the two sections,
those sections being the ones linked from the top:

* Comparing the Data Storage Options
* Selecting a Datastore

In this particular case, but certainly not all cases on all pages, the
repetition about the algorithm and costs might be better if cleaned
up.

In the second section there is information about how to select a radio
button and what to click.  If this type of information is needed, it
might be better to ensure that the prompts are better.  For example:
radio buttons should not be labeled simply A and B.  If the prompts
are good enough then it might be better not to write about them in the
documentation.

There is also a screen capture.  If the user will see it when the user
goes to use it, I am not sure what the value is to have a screen
capture especially if the screen is a simple one.

I know there must be opposition to fixing these problems otherwise
they would have already been fixed but there exists an interesting
equilibrium.
