IT's 123_108_2016. Every time I deploy the app, the error dissapears and 
appears after a few hours.

Can you try var_dump($nr) to check its content?

Hello guys, Looking through my app logs, I saw an awkward error 
regarding tasks:


PHP Fatal error: Uncaught exception 
'google\appengine\runtime\ArgumentError' with message 'An error 
occurred parsing (locally or remotely) the arguments to 
taskqueue.BulkAdd().' in

Do you have any idea what is wrong here? Here is my code:

$nr = str_replace('/','-',$this->input->post('number'));
$queue = new PushQueue();
$task = new PushTask('/queue/refreshFolder', ['folder' => $nr]);
$queue->addTasks([$task]);

Re: [google-appengine] Java & Python Modules in Same App -- How?

[PK]

Hi Andrei,

I have not done it but my understanding is that it is possible. You would need 
multiple modules. The python modules would use yaml files. The Java modules xml 
files. The default module would have the one dispatch.yaml file that will route 
to the appropriate modules. Modules share the same state in stateful services 
like the datastore, memcache etc. 

An example would be useful, I agree.

[google-appengine] Java & Python Modules in Same App -- How?

[Andrei Matveev]

Hello,

I'd like to experiment w/ mixed language modules in App Engine. Currently 
I've got several Python based modules up & running already. I'd like to add 
a Java module for kicking off Dataflow jobs (I understand that in order to 
do this I might need to venture beyond the GAE sandbox and delve into the 
Managed VM terrain...). 

I couldn't find any examples or guides for building/managing Java & Python 
mixed module applications. Can anyone point me in the right direction? Can 
Python's YAML based configs be made to play nice w/ Java's 
appengine-web.xml configs?

Thank you in advance for taking a look!

[google-appengine] Production Issue not responded on the issue tracker

[Aswath Satrasala]

Hi,
We had a latency issue for a request serving from a fresh instance.  It was
suggested to create a issue in the tracker for better resolution.
A production issue on the appengine issue tracker was created  It was
answered and followed up by the appengine team during the initial period of
the issue.
But there is no response from the appengine team on the issue lately for
one month. I have been following up on the issue tracker every week lately,
but still no response.

FYI, the issue is
https://code.google.com/p/googleappengine/issues/detail?id=12564

Can someone help on this for getting the attention and resolution.

[google-appengine] Cloud Trace API on AppEngine - latency and other questions

[Alexander Bertram]

Hi there,
I've started to look at using the new CloudTrace API to add information on 
CloudSQL requests to traces on AppEngine requests, which we desperately 
need, but I encountered two challenges:

First, even batching all the traces for a request together in a single API 
call adds about 100 ms latency to the request (that's the /urlfetch.Fetch 
bar below), which I don't think I can stomach in production. Is there 
anyway to piggy back custom trace data onto AppEngine's existing reporting 
mechanism, which seems to run independently of requests? 

Second, is there any way to detect which requests AppEngine has sampled for 
tracing so that we only spend the time to report traces for those that are 
sampled for RPC traces?

Thanks,
Alex

Is that an error output from your application, in the logs? Or a

But nevermind i think what you said is the cleaner way how to

[google-appengine] Re: Reading existing entity from DB

[Nick]

I think you've been given some good pointers in the right direction, I'll just 
add that you need to read and understand the eventual consistency, 
transactional and cross entity group (XG) transaction docs for the datastore.

My guess is based on your question you haven't wrapped your head around it, and 
as a result your data models and subsequently data are going to get broken. 
Fixing them after go live will be hard, so you need to get a lot closer now.

Once you've got the basic concepts down, it should become clearer how to model 
this, and why this is happening.

In order for this to work as you expect you need strong consistency, which 
typically means a) have your entities be a part of the same entity group and b) 
do the query inside of a transaction.

As others have pointed out it’s much, much easier to simply use the id as they 
key and fetch by key. Though you still need to do the logic below inside of a 
transaction.

We are also facing the same issue though we have billing enabled in our

Any clues ?

[google-appengine] Re: Reading existing entity from DB

[Louise Elmose Hedegaard]

Hi guys,

Thank you for your answers.
I do not think I have explained my problem properly though when I read your 
answers.

I have a table "order" where I save different information about an order. 
The unique id of the order comes from an external system, and I want to 
save this unique id for the order.
When an order is updated in the external system, I want to update the GAE 
datastore accordingly. 
For this reason I first check whether the order that was updated in the 
external system already exists in my datastore. If it already exists I 
update it, if it does not already exist, I create the order in the 
datastore.
My problem is that I use this:

datastore.prepare(query).asSingleEntity();

which fails, as there are more than one entity with the unique id.
I do not understand how several entities can be created with the same 
unique id, when my logic says:

Entity entity = getEntity(uniqueId);
if (entity == null){
  createEntity();
}else{
  updateEntity();
}

It is as if the getEntity check does not detect that there already is an 
entity with the unique id.
It does seem that this is caused by a timing/concurrency issue - the 
external system sends two updates approximately at the same time, but 
shouldn't the datastore be able to handle this?

My first attempt of getEntity was:

Query query = new Query(OrderDBFields.ORDER_TABLE_NAME).setFilter(new 
Query.FilterPredicate(OrderDBFields.ID, Query.FilterOperator.EQUAL, id));
return datastore.prepare(query).asSingleEntity();

My second (confused attempt) is:


Transaction txn = datastore.beginTransaction();
Key orderKey = KeyFactory.createKey(OrderDBFields.ORDER_TABLE_NAME, 
id);
Entity orderEntity = null;
try {
orderEntity = datastore.get(orderKey);
} catch (EntityNotFoundException e) {
orderEntity = null;
}
txn.commit();
return orderEntity;

Any input is appreciated,
Thanks
-Louise

[google-appengine] Re: Reading existing entity from DB

[timh]

Having a unique id that is only a property and not the key of the entity 
makes it hard.
Are you generating the ID - is it sequential, or just unique (ie an email 
address) if the later, you could reliably use a combination of transactions 
and a child entity with a key of the unique id, and the ancestors key).

You don't even have store any data.

This can be reliable as you are able to use get operations in a transaction.

Anything entity you fetch by a query (unless it's an ancestor query) will 
be liable to eventual consistancy issues.

[google-appengine] Re: How can i set an order for .jar files in WEB-INF/lib

[Manuel Werder]

yeah it was: 
com.google.apphosting.api.ApiProxy$FeatureNotEnabledException: The Socket 
API will be enabled for this application once billing has been enabled in 
the admin console.

but as i said it was already enabled. so i deployed it to another project 
where billing already is enabled also. 
And it works there. Seems to be a bug with my project or something?
Thanks for your help though,
