Re: [appengine-java] gae不支持事务？

If following operation throws an exception,we can not rollback the first
transaction, because it is already committed. What I can think of right now
is, you can manually delete it. but it is not the genuine solution.

Why don't you create owned relation between these two table?
Tell me about your thoughts?

Re: [appengine-java] gae不支持事务？

As article on http://www.keakon.net/article/1843 suggests , you can create
task queue on successful completion of 1st transaction , same can be done
when exception  occurred  in 1st transaction.
I did not try this solution but it seems like good option.

By this way we can achieve atomicity like in banking example .

[appengine-java] Cannot resize a .tif image using the ImagesService on the dev app server

2010-12-16 Thread Ian Marshall

I refer to the related post entitled WARNING: No image reader found
for format ico. An ImageIO plugin must be installed to use this
format with the DevAppServer. dated 7th June 2009 at:

http://groups.google.com/group/google-appengine-java/browse_thread/thread/7a44035eea5b1f4d/5fcd8b0a21f41db3?lnk=gstq=WARNING%3A+No+image+reader+found+for+format+%22ico%22.+An+ImageIO+plugin+must+be+installed+to+use+this+format+with+the+DevAppServer#5fcd8b0a21f41db3


where a query about the dev app server warnings below was raised, but
after Jason of Google asked a supplementary question he received no
response from the original poster.

My web app uploads an image file from a web browser user and then, if
the file is larger than around 900kB I use the GAE/J ImagesService to
reduce the image data size to this level. An extract of my relevant
code is:

byte[] baImageSource = [...];// Data from an uploaded image file
int nNewWidth  = [...];  // Calculate correct shrinkage
int nNewHeight = [...];  // Calculate correct shrinkage

Image imgSource = ImagesServiceFactory.makeImage(baImageSource);
ImagesService isService = ImagesServiceFactory.getImagesService();
Transform tfrm = ImagesServiceFactory.makeResize(nNewWidth,
nNewHeight);
Image imgNew = isService.applyTransform(tfrm, imgSource);
byte[] baResult = imgNew.getImageData();// The shrunken image
data


When I run my ImagesService code on my GAE/J development server
((latest) version 1.4.0) I get the two warnings:

16-Dec-2010 10:40:18
com.google.appengine.api.images.dev.LocalImagesService init
WARNING: No image reader found for format ico. An ImageIO plugin
must be installed to use this format with the DevAppServer.

16-Dec-2010 10:40:18
com.google.appengine.api.images.dev.LocalImagesService init
WARNING: No image reader found for format tif. An ImageIO plugin
must be installed to use this format with the DevAppServer.


My code runs well for shrinking .jpg files, but when I try this for
a .tif file of size 6.11 MB I get an IllegalArgumentException on my
call to ImagesService.applyTransform(...). (I set out a stack trace at
the foot of this post.)

I have a few questions for those interested:

  ·  How do I get a tif ImageIO plug-in for the ImagesService ()?
  ·  Should this plug-in be supplied with the GAE/J SDK in future
releases?
  ·  Does this issue apply to the dev app server only (I have not yet
deployed this to production)?

Cheers,

Ian Marshall

 You can not operate on two entities in single transaction unless both

 First delete CityNum  in one transaction and then delete ScheduleProcess

[appengine-java] Re: storing unowned objects(one to many) in datastore

2010-12-16 Thread WillSpecht

Why do you want to store both in the same transaction? To me, it seems
transactions are used to guarantee two things happen.  eg.  you don't
want to delete one record without making sure the a log of deleted
records is updated.  Transactions are also used to prevent collisions,
eg. I don't want two users adding to a counter at the same time and
one of their adds is lost.

It seems neither of these is likely.  It is unlikely that a new Person
will be created and before the system can save their mobile, some
other user will try and edit it.  It is also unlikely that either of
these will fail and not fail gracefully.  If you try and add a user in
one transaction then try to add a mobile in a second transaction
either both will succeed or fail.  Same outcome as a single
transaction.  Or one of the two fails and you simply try it again or
delete the one that didn't fail and inform the user.

If you really need a single transaction you can put both items in the
same entity group using a key builder.

You can see an example here under Creating Entities With Entity Groups
http://code.google.com/appengine/docs/java/datastore/transactions.html

 Dec 15, 10:16 pm, Didier Durand durand.did...@gmail.com wrote:
 Hi,

 If they don't belong to the same entity group, you will raise an
 exception by trying to store 2 objects in a single transaction.

 2 ways to handle that:

    a) you make Mobile belong to same entity group as Person so you'll
 be able to store both in a single transaction. I understand in your
 question that you can't go this way.
    b) you store one let's say Person in first transaction and during
 this transaction, you start a task as part of the transaction: You
 can enqueue a task as part of a datastore transaction, such that the
 task is only enqueued—and guaranteed to be enqueued—if the transaction
 is committed successfully. Tasks added within a transaction are
 considered to be a part of it and have the same level of isolation and
 consistency. as said 
 inhttp://code.google.com/appengine/docs/java/taskqueue/overview.html#Ta...

 Hope it helps

[appengine-java] Re: Files Limitation 3000

2010-12-16 Thread Francois Masurel

Hi Ravi,

I'm putting all the generated GWT files in a zip file and I'm serving
them with a specific servlet.

It works fine and even allows me to do some GWT versioning : /gwt
module = servlet/version/path to gwt file

Remember that, if you change the default GWT module path (like adding
a version number in it), you need to override the
RemoteServiceServlet#doGetSerializationPolicy method.

[appengine-java] Channel API problem

2010-12-16 Thread Tarun

I have been trying to use the newly launched Channel API on SDK 1.4 in
my project. I try to push a message to client which actually pops up a
notification but I am getting the ChannelFailureException.
Here is the code:
TestServlet Where the token is created:
public void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
PrintWriter out = resp.getWriter();
resp.setContentType(text/html);
// Creating the userID on the basis of the session id
String userId = req.getSession().getId();
// Starting the ChannelService of the channel API
ChannelService channelService = ChannelServiceFactory
.getChannelService();
// Creating the client token
String token = channelService.createChannel(userId);
req.getSession().setAttribute(token, token);

out.println(html);
out.println(head);
out.println(titleThis is a servlet which will be used to try 
the
new Channel API/title);
out.println(/head);
out.println(body);
out.println(a href=\/ChannelAPI.jsp\Click Here/a to 
recieve a
notification on the next page using channel API);
out.println(/body);
}
}

Channel API.jsp
script
channel = new goog.appengine.Channel('%= userId%');
socket = channel.open();
//socket.onopen = onOpened;
socket.onmessage = onMessage;
socket.onerror = onError;
socket.onclose = onClose;
onMessage = function (message){
$.pnotify({
pnotify_title: 'Regular Notice',
pnotify_text: message.data
});
};

onError = function (description,code){
$.pnotify({
pnotify_title: 'Uh Oh!',
pnotify_text: 'something went wrong',
pnotify_type: 'error',
pnotify_hide: false
});
};
 /script

Send Message servlet:
public void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {

String userId = (String) req.getSession().getAttribute(token);
ChannelService channelService =
ChannelServiceFactory.getChannelService();
channelService.sendMessage(new ChannelMessage(userId,
This is the message that has been sent));

}

}

The stack trace I got
Uncaught exception from servlet
com.google.appengine.api.channel.ChannelFailureException: An
unexpected error occurred.
at
com.google.appengine.api.channel.ChannelServiceImpl.sendMessage(ChannelServiceImpl.java:
59)

Can you tell me if there is something wrong with the code or with the
Channel API?

Thanks in advance,
Tarun

 Yet, I do face one last issue with an unexpected quota : blobstore bytes
 read.
 This quota cannot be tuned via the billing settings, and it's not clear
 whether it limits the speed of my process or not when it's reached.


 See ? Yep, it's a lot of bytes readŠ
 Could someone confirm that the blob csv file is *NOT* fully fetched each

[appengine-java] Re: Synchronized reads/writes on a memcache variable

2010-12-16 Thread Erwin Streur

I agree. You should seriously consider the method that you are using.
The MemCacheService is a component designed to increase (mostly read)
access to the Datastore. Users of this service should not rely upon
the presence of data in the MemCache, but should use the Datastore and
its transaction support.

If you really want to use the MemCache you can apply an optimistic
locking approach by using with versioned data
- use a counter for version
- get current version
- get List using Key derived from current Version
- modify the List
- increment counter for Version and get value (atomic operation)
- verify that new version is 1 higher then originally retrieved one
- in case it is, store modified list under key derived form new
version
- in case it isn't, get the list for the real previous version and
store it under the latest version key. The system should now be in
consistent state again

You can apply different strategies for recovery, either just report
ConcurrentModificationException or retry the whole operation

Re: [appengine-java] Multiple Async get vs one Sync batch get?

2010-12-16 Thread Ikai Lan (Google)

You're talking about the datastore API? Underneath the hood, synchronous
gets just make asynchronous calls and block on Future.get() anyway. Making a
single synchronous batch get would translate to a single asynchronous RPC
with multiple keys vs. multiple asynchronous get RPCs. I suspect the single
batch call will perform better from a CPU cost/quota perspective, but I'd
defer to AppStats benchmarks as the authoritative answer.

[appengine-java] com.google.appengine.api.datastore.Text does not preserve formatting

2010-12-16 Thread Ojasvi

Hi I am using Java + Jdo to store data. I am able to store Text. The text I 
get loses all its formatting ( new lines spaces are all converted to single 
space )
is their any way to prevent the same ? I have read both the community and 
official FAQ and searched this group.
Please help

Re: [appengine-java] Multiple Async get vs one Sync batch get?

2010-12-16 Thread Gal Dolber

Yes, I am talking about datastore api.

I made some isolated tests and the batch always wins (no by so much).

But in my app, when I break the batch into multiple async gets, I can start
processing each async get result (and doing another api calls) before... and
it seems to be perform better.

I'll keep doing tests and post if find anything interesting.
Thanks!

[appengine-java] Re: Newly deployed app doesn’t se em always reflected on the server.

2010-12-16 Thread nnhobbit


I think for sure there's some sort of delay of deployment sometimes.
It does not always happen.

You don't have to deploy your app again, just have to wait long enough
(time frame unpredictable) for your new deployment instance get going.
Even though in the console says the app is deployed and running, it is
not.

This unpredictability of deployment is really some serious issue.

p.s. the version number is changed, it is set to default, and it's
definitely no cache.

Does the email address used in your From have administrator privileges for

Re: [appengine-java] Re: Not sending email with Javamail and no error

I have much the same code although I set more headers.
How about adding yourself as a BCC and/or CC?
Also, do you see any utilization  in your Quota details - Mail API Calls
and Recipients Emailed ?

Re: [appengine-java] Re: storing unowned objects(one to many) in datastore

Hi,
I can not create entity group because both are both classes can
exists independently, It can be unowned relation  between them.
I want both should be stored  in datastore or none of
these(Atomic behavior ) . If one entity is not stored other entity must not
store in datastore .

Didier's suggestion looks good , but i did not try .

 Why do you want to store both in the same transaction? To me, it seems
 transactions are used to guarantee two things happen.  eg.  you don't
 want to delete one record without making sure the a log of deleted
 records is updated.  Transactions are also used to prevent collisions,
 eg. I don't want two users adding to a counter at the same time and
 one of their adds is lost.

 It seems neither of these is likely.  It is unlikely that a new Person
 will be created and before the system can save their mobile, some
 other user will try and edit it.  It is also unlikely that either of
 these will fail and not fail gracefully.  If you try and add a user in
 one transaction then try to add a mobile in a second transaction
 either both will succeed or fail.  Same outcome as a single
 transaction.  Or one of the two fails and you simply try it again or
 delete the one that didn't fail and inform the user.

 If you really need a single transaction you can put both items in the
 same entity group using a key builder.

 You can see an example here under Creating Entities With Entity Groups
 http://code.google.com/appengine/docs/java/datastore/transactions.html

  Hi,
 
  If they don't belong to the same entity group, you will raise an
  exception by trying to store 2 objects in a single transaction.
 
  2 ways to handle that:
 
 a) you make Mobile belong to same entity group as Person so you'll
  be able to store both in a single transaction. I understand in your
  question that you can't go this way.
 b) you store one let's say Person in first transaction and during
  this transaction, you start a task as part of the transaction: You
  can enqueue a task as part of a datastore transaction, such that the
  task is only enqueued—and guaranteed to be enqueued—if the transaction
  is committed successfully. Tasks added within a transaction are
  considered to be a part of it and have the same level of isolation and
  consistency. as said inhttp://
 code.google.com/appengine/docs/java/taskqueue/overview.html#Ta...

No ideas, anyone?

 I refer to the related post entitled WARNING: No image reader found

 http://groups.google.com/group/google-appengine-java/browse_thread/th...

 where a query about the dev app server warnings below was raised, but
 after Jason of Google asked a supplementary question he received no
 response from the original poster.

 My web app uploads an image file from a web browser user and then, if
 the file is larger than around 900kB I use the GAE/J ImagesService to
 reduce the image data size to this level. An extract of my relevant
 code is:

         byte[] baImageSource = [...];    // Data from an uploaded image file
         int nNewWidth  = [...];          // Calculate correct shrinkage
         int nNewHeight = [...];          // Calculate correct shrinkage

         Image imgSource = ImagesServiceFactory.makeImage(baImageSource);
         ImagesService isService = ImagesServiceFactory.getImagesService();
         Transform tfrm = ImagesServiceFactory.makeResize(nNewWidth,
 nNewHeight);
         Image imgNew = isService.applyTransform(tfrm, imgSource);
         byte[] baResult = imgNew.getImageData();    // The shrunken image
 data

 When I run my ImagesService code on my GAE/J development server
 ((latest) version 1.4.0) I get the two warnings:

         16-Dec-2010 10:40:18
 com.google.appengine.api.images.dev.LocalImagesService init
         WARNING: No image reader found for format ico. An ImageIO plugin

 com.google.appengine.api.images.dev.LocalImagesService init
         WARNING: No image reader found for format tif. An ImageIO plugin
 must be installed to use this format with the DevAppServer.

 My code runs well for shrinking .jpg files, but when I try this for
 a .tif file of size 6.11 MB I get an IllegalArgumentException on my
 call to ImagesService.applyTransform(...). (I set out a stack trace at
 the foot of this post.)

 I have a few questions for those interested:

   ·  How do I get a tif ImageIO plug-in for the ImagesService ()?
   ·  Should this plug-in be supplied with the GAE/J SDK in future
 releases?
   ·  Does this issue apply to the dev app server only (I have not yet
 deployed this to production)?

 Cheers,

 Ian Marshall

[google-appengine] This request used a high amount of CPU and may soon exceed its quota - 2010/2011

2010-12-16 Thread Matija

Hi, I am using google app engine from beginning. From the time when there 
was high cpu quota tickets. I understand difference between request time, 
cpu and api time. 

In one of my request I am putting two objects in one batch operation to 
datastore (from same entity group in transaction, although this 
is irrelevant for this discussion). I noticed in log these request/cpu/api 
times:

12-16 02:03AM 35.944   200 198ms 1847cpu_ms 1700api_cpu_ms 
12-16 02:03AM 35.813   200 128ms 1828cpu_ms 1700api_cpu_ms 
12-16 02:03AM 35.712   200 107ms 1829cpu_ms 1700api_cpu_ms 
12-16 02:03AM 35.586   200 145ms 1865cpu_ms 1700api_cpu_ms 
12-16 02:03AM 35.524   200 182ms 1810cpu_ms 1700api_cpu_ms 
12-16 02:03AM 35.387   200 203ms 1938cpu_ms 1700api_cpu_ms 
12-16 02:03AM 35.438   200 151ms 1791cpu_ms 1700api_cpu_ms 
12-16 02:03AM 35.298   200 171ms 1829cpu_ms 1700api_cpu_ms

I would probably ignore there lines if they are not in red color with 
triangle sign to warn me about 'high amount of cpu usage'. 

Reason for this 'high' api usage is index creation. Cost for first object is 
around 1200 api_cpu_ms and for second 500 api_cpu_ms (some changes and 
appstat revealed data). 

First object has 8 indexes where first attribute is list of strings (from 5 
to 11 members, this usage is for 11 members). This 8 indexes are for ability 
to sort on 4 columns (ascending and descending). If I leave this list empty, 
api_cpu_ms is around 330 ms for first object. Of course I must not leave 
list empty if I want this user interface feature.

I understand everything about this 'issue' and I am fine with 'high' cpu 
usage, because my request time is around 160 ms, top 200 ms.

Question: Is Google App Engine fine with my 'high' cpu usage ? Will I 
be penalized in any way (new instances, throtle, ...) because of this 'high 
abount of CPU' ?

If GAE is fine and I will not be penalized why don't you change this 
'coloring' schema to use only request time or maybe request time with (cpu 
time - api time) ?! This red color will make me crazy ;)

It seems every request that used more than 1000 cpu ms will be consider as
high amount of cpu usage.

If GAE is fine and I will not be penalized why don't you change this
'coloring' schema to use only request time or maybe request time with (cpu
time - api time) ?! This red color will make me crazy ;)

Re: [google-appengine] how can i write Arabic in app engine

I suggest you always use UTF-8, not windows-1256.

However, if you insist on using windows-1256, you should encode your unicode
output to str:
self.response.out.write(u'some unicode string'.*encode*('windows-1256'))
or:
self.response.out.write('some windows-1256 string') # don't decode it

 So I try to do that at the godaddy DNS panel, but here is the end of the
 game, godaddy says that a wildcard CNAME is not allowed.

 So how have others solved this ? Switched to another DNS provider ? Which
 one ? Or did I just so something wrong ?

[google-appengine] Forcing bulkloader to create missing properties as None

2010-12-16 Thread Justin

How can I force the [csv] bulkloader to create entities with 'None'
property values if the relevent bulk data field is empty, as opposed
to assuming the entity model property is missing ?

I've tried

- using 'import_transform: transform.none_if_empty(str)' in
bulkloader.yaml
- using 'db.StringProperty(default=None)' in the model definition

Neither of which seems to work; what I find is

- empty fields appear as blanks in the dev_appserver datastore viewer
[if I put a model to the datastore with an explicity 'None' field via
the interactive console, it appears as 'None']
- I can't query the empty fields using Query.filter(field = , None)
[the filter just gets ignored]

Thank you.

[google-appengine] Google App Engine Dashboard API or iPhone app?

2010-12-16 Thread Xin Liu

Hi,

Will there be an API that can expose all details we saw from Google App 
Engine Dashboard, so that we can do a lot of interesting things with it. Or 
will there be an iPhone app for Google App Engine Dashboard?

As an iOS/GAE developer I'd really love to see the combination.

Cheers,

Xin

[google-appengine] Storing properties dict as db.Model field

2010-12-16 Thread Justin

What's the approved way of doing this ?

I don't want the overhead of creating a separate db model.

I don't see a db.DictProperty [equivalent of db.ListProperty].

Right now I use a db.TextProperty, and serialise/deserialise the dict
with yaml.

I'm guessing this isn't the 'approved' way of doing things.

I think there is no approved way.

Which method will depend heavily on what you are sticking in your dict, how 
big it is etc..

I personally pickle dicts and stick them in a BlobProperty ;-)

 Hi, I am using google app engine from beginning. From the time when there
 was high cpu quota tickets. I understand difference between request time,
 cpu and api time.
 In one of my request I am putting two objects in one batch operation to
 datastore (from same entity group in transaction, although this
 is irrelevant for this discussion). I noticed in log these request/cpu/api
 times:
 12-16 02:03AM 35.944   200 198ms 1847cpu_ms 1700api_cpu_ms
 12-16 02:03AM 35.813   200 128ms 1828cpu_ms 1700api_cpu_ms

 12-16 02:03AM 35.298   200 171ms 1829cpu_ms 1700api_cpu_ms
 I would probably ignore there lines if they are not in red color with
 triangle sign to warn me about 'high amount of cpu usage'.
 Reason for this 'high' api usage is index creation. Cost for first object is
 around 1200 api_cpu_ms and for second 500 api_cpu_ms (some changes and
 appstat revealed data).
 First object has 8 indexes where first attribute is list of strings (from 5
 to 11 members, this usage is for 11 members). This 8 indexes are for ability
 to sort on 4 columns (ascending and descending). If I leave this list empty,
 api_cpu_ms is around 330 ms for first object. Of course I must not leave
 list empty if I want this user interface feature.
 I understand everything about this 'issue' and I am fine with 'high' cpu
 usage, because my request time is around 160 ms, top 200 ms.
 Question: Is Google App Engine fine with my 'high' cpu usage ? Will I
 be penalized in any way (new instances, throtle, ...) because of this 'high
 abount of CPU' ?
 If GAE is fine and I will not be penalized why don't you change this
 'coloring' schema to use only request time or maybe request time with (cpu

[google-appengine] Re: deploy restlet onto gae with error

2010-12-16 Thread Richard Berger

I was able to solve this problem.  There were a few steps, but
basically it comes down to updating libraries and modifying the
web.xml file.

Phase 1...
1. Replace the 7 jar files in WEB-INF/lib
(org.codehaus.jackson.core.jar, org.codehause.jackson.mapper.jar,
org.restlet.ext.gwt.jar, org.restlet.ext.jackson.jar,
org.restlet.ext.servlet.jar, org.restlet.ext.xml.jar, org.restlet.jar)
with newer versions I used the ones in restlet version 2.1 Milestone
1.  (If in Eclipse make sure the build path gets updated to use the
new jars).  These jars are available in the GAE download.
2. Replace the one jar in the lib directory (org.restlet.jar) with the
2.1 Milestone 1 version.  This jar is in the GWT download.

Phase 2
1. Change the web.xml file, as it currently refers to a class that no
longer exists (GwtShellServletWrapper).  Here's the relevant snippet.
servlet
servlet-nameadapter/servlet-name
!--  
servlet-classorg.restlet.ext.gwt.GwtShellServletWrapper/
servlet-class --

servlet-classorg.restlet.ext.servlet.ServerServlet/servlet-class
init-param
param-nameorg.restlet.application/param-name
param-
valueorg.restlet.example.gae.serialization.server.TestServerApplication/
param-value
/init-param
/servlet

And then it worked.

[google-appengine] App Redirecting to Zimbio

2010-12-16 Thread Iambeaker

Excuse my ignorance, first time poster, first time Google App
Developer...

I created an app but when I access it from my boss's computer (and
about 10 other computers) it redirects to zimbio.com.  However, I am
able to access it from my personal computer and work computer.

I do not have any code to allow the redirection.  Does the user need
to sign into their Google account to access this app or do they have
to follow some other workaround?

I would like to be able to give people the app website, and have them
be able to use it without them needing to sign into anything.

Any thoughts?

[google-appengine] problem using TextProperty

2010-12-16 Thread feynmansbastard


hello,

I'm running GAE 1.4 and python 2.5.2

I built an application on the development server which worked fine.
It's a simple application that takes data from external clients, puts
it in the datastore, and then allows users to view it on the web.

One of my fields in this model I recently switched from a
StringProperty to a TextProperty to allow larger inputs.

Since I have done this, I have not been able to get this field to
persist any data.   When I try to access this data in django or even
directly through a webbrowser, it's no longer present.

here is my model

class Request(db.Model):
   result = db.TextProperty()

class NewRequest(webapp.RequestHandler):
def post(self):
   r = Request()
   r.result = self.request.get('result')
   r.put()
   self.response.out.write(r.key())
   # in the development console regardless whether result is
string or Text I can see result here
   logging.info(request: +r.result);

# call with http://localhost:8080/test?key=keyprovidedaftersubmittingabove
class test(webapp.RequestHandler):
def get(self):
 r = Request.get(self.request.get('key'))
 # in the console I can see this result if the type is
String, but not when TextProperty is used
 logging.info(request: +r.result);

what am I doing wrong? I can't find any references to anybody with
this problem, so it must be something really simple.

[google-appengine] Memcache broken with Always On?

2010-12-16 Thread Tom Phillips

I posted on this this in the java forum, but no traction there and I
suspect it's not java specific.

Memcache entries seem to be being scoped to an instance, not global.
After a cache entry is made, it can be retrieved fine for any request
that goes to that same instance. Any request to one of the other
instances never finds the entry in the cache.

Bug in Always On? Bug in 1.4.0? Design intent?

Thanks,
Tom

 in appcfg.py?  What file would I have to modify in order to do this?

 Is there any easier way in python to automate user input?

 Any help would be appreciated.

The only penalty is that requests that take more than 1000 mS will not
benefit from automatic scaling. And you'll use more quota, obviously.

2010-12-16 Thread Tom Phillips

Certainly Ikai,

Firstly, some of my logs (url and classes slightly modified to hide
some app details) that show how only the same instance picks up the
entry. I'm determining and logging the instance using a UUID that I
assign to a static class variable. The key for the cache lookup is
passed in as a request query parameter to the followup requests.

Here are two runs of the code to follow. In each, the bottom log is
the cache entry being added. The next two are subsequent requests that
both look for the entry. The entry is only found when then instance
matches, regardless of which follow-up request.

This first run shows how the bottom instance is different from the one
that services both followup requests. So they don't find the entry:

[google-appengine] Instance scaling with problems

2010-12-16 Thread Tomas Alaeus

Due to lack of information about when App Engine starts new instances,
how it affect performance and side effects of scaling up I have here
made a short summary from my own experiences so others won't have to
find it out the hard way.

I still don't have any long experience with App Engine, but I see it
as a very promision product. The problems I see with it are mostly
associated with how the scaling of instances works. Mainly because NO
information exists on how it works. Not even the support (by mail)
seem to know how it works.

I've tried to split this post into three parts for readability. Sorry
for the wall of text.

__

First some basic facts on the non-billing (free) and billing enabled
versions.

The free version can start at most 30 instances, and the billing
enabled one have no hard limit. However, it got a soft limit which
starts at 30 and is incremented by 10 when needed. When the
application reaches its soft cap of instances and stays there for
about 10-15 minutes, and it still lacks performance, then the soft cap
is incremented by 10. If it still needs more it will be incremented by
10 after a few minutes, and so on.

This all looks fine (although it isn't mentioned anywhere, which lead
me to bad decisions). What is worse is some sort of minimum number of
instances, which I will refer to as min instances, which App Engine
will try to start up before activly forwarding the requests to hot
instances.

After a lot of testing, my results say that min instances starts on 1,
and is incremented by 1 for every soft cap increment. That is, this
value will be about a tenth of the soft cap.

__

What is the effect of this min instances more exactly?

If it is set to 4 then if there is/are: 0 instance started: An
instance starts, user feel a cold start 1 instance started: 25% of
user getting an hot instance, 75% of instance startup. 2 instances
started: 50/50% of getting an hot or cold instance. 3 instances
started: 75% of getting an hot... 4+ instances started: Now it behaves
as everyone believes.

Apart from being strange and not documented, there are some mayor
issues with this:

* It is not reverted! Even if the application is idle for a week, the
min instances are not lowered.

* Warmup requests is not triggered for the first min instances
instance startups.

* Always on starts only exactly 3 instance, if you sometime earlier
have boosted your min instance past 3 then users will still notice
cold starts, even if your application have been idle for the past
hours!

__

My story:

I didn't know about the soft cap, and hit the roof pretty quickly with
my stress tests. I aborted the tests then and asked support why it
didn't start more instances. They just said I should have the test run
longer. And so I did. I increased the soft cap to 100 instances or
something and felt that the service would handle anything that was
thrown at it.

Now when my application have gone live the first users will more or
less all be handeled by cold starts. It is always hard to predict the
number of users, but in the worst case the first users will get scared
away because of the performance issues and also warn other users about
it.

If by any means a Google employee knows about this issue, and knows
how to revert the min instances (without interrupting the service)
then please notify me!

I'm pretty sure Google is not just randomly sending your users to some

switch DNS providers.

You app can be served without forcing users to log into anything.

I do not have any code to allow the redirection. Does the user need

I would like to be able to give people the app website, and have them

Hi KP,
  I am not sure what you are asking, but these docs might be useful:
   Python:

   Java:
 
http://code.google.com/appengine/docs/java/config/appconfig.html#Static_Files_and_Resource_Files

  Static files are handled like, well, static files.  You specify the
path(s) for your static content, then when a user requests one of
those paths the static content is served.

Re: [google-appengine] Re: max_backoff_seconds - working?

2010-12-16 Thread Nicholas Verne

Vlad,

Your case is a bit of an edge case for us. At the time your task is
dispatched, do you have any other tasks still in the queue scheduled
to execute within the next twenty seconds? If not, your queue is
considered empty and will next be checked for tasks to dispatch in
twenty seconds time. If, during this interval, your task that was
running now fails, the task's retry won't be able to run until after
this twenty seconds has elapsed.

If there were other tasks in the queue scheduled to execute during the
twenty seconds after your task's eta, you might find your task meeting
its 7 second retry backoff more precisely.

 Hi Nick,

 Task schedule delays (best effort) are expected but this is not the case.
 Take a look at the log excerpt below which shows a task with 6 reties.
 Retries are perfectly timed on flat 20sec back off schedule. In other words
 I have never seen task reties follow what I put in my queue.yaml. Instead
 they *always* do 20 sec backoff.
 Another fact that might help is this has not changed at all with SDK 1.4.0
 release. This picture was exactly the same before the release.

 My queue.yaml

 queue:
 - name: default
   rate: 20/s
   bucket_size: 100
   retry_parameters:
     task_age_limit: 120s
     min_backoff_seconds: 1

[google-appengine] Custom Domain

2010-12-16 Thread david

Hi,

I configured my appengine app with my domain www.mydomain.com.co, but
it doesnt works just with mydomain.com.co (without subdomain).

There is a restriction? What could be wrong?

Thx a lot!

You can't do CNAME for bare domains

Some DNS providers have the facility of allowing you to specify a redirect 
from the bare domain to you www.

[google-appengine] Re: Appengine's Turkey problem

Shouldn't someone solve this problem?

 It took me a long time to figure out that the reason of my domain
 name(www.something.com) on Appengine not working is that Youtube IP's
 are banned in Turkey.

 So when i ping my domain, It can't reach ghs.l.google.com

 Should Google use seperate IP's for domain related things or should we
 forget about Turkey if we use Appengine?

Re: [google-appengine] Re: Newbie Q - Public IP address_DNS Server?

Nope - the best I can think of  ghs.google.com  although that is where
inbound traffic is going to and not necessarily where url fetch hits
originate from. I can't imaging all the traffic from the url fetch pool
coming from any single ip address.

FWIW, A web service whitelisting an ip address is poor security because it
is relatively easy for public relays to see where the traffic is coming from
and then spoof hits to come from those sources. It is much better to sign
your web service requests with a key like AWS SimpleDB does.

 Hello everyone,

 I come back on this subject because I need to set a public IP on my GAE.
 I need to call a Web Service from the server but this web service need a IP
 to authorize anyone to call it. When I lauch GAE in local, there's no
 problem because I can identify my IP.

 Is there a solution to set a public IP on a Google App Engine?

 Thanks a lot for your answer!

[google-appengine] Re: Appengine's Turkey problem

2010-12-16 Thread Tim Hoffman

Hi

I don't really believe it is solvable by google.

If they add a new pool of addresses for appengine, and some apps turn up on 
appengine that 
any particular government doesn't like, they will block access to that range 
and you are
back in the same situation.

All anyone can do is educate and lobby their government.

Publishing the uncompiled files is in the works! I know it'll be useful for 
those of you using closure (it could save a lot of code size). No definite 
time line but I'm working on it now.

[google-appengine] Re: [Channel API] How do I know the token expired or not in server side?

2010-12-16 Thread Moishe

I think this was also asked/answered over in the python group, but I'll post 
here too for the sake of completeness:

1. Token expires two hours from when you call create_channel. So if you 
wanted to store it server side, you could also store a time stamp. Note that 
the expiration's accuracy is on the order of seconds, not clock cycles, so 
don't worry about trying to get an exact timestamp match.

2. Notification of client connect/disconnect is in the works, but not 
available right now.
