Service Worker Scope - scope

Isn't this a wrong diagram, or am I missing something? Both trending.html & fav directory already under the worker's scope, so why it's skipping trending.html request?!

EventHubConsumerClient Apache Qpid memory leak?

I am reading events from an Azure EventHub cluster synchronously via the receiveFromPartition method on the EventHubConsumerClient class.
I create the client once like so:
EventHubConsumerClient eventHubConsumerClient = new EventHubClientBuilder()
.connectionString(eventHubConnectionString)
.consumerGroup(consumerGroup)
.buildConsumerClient());
I then just use a ScheduledExecutorService to retrieve events every 1.5s via:
IterableStream<PartitionEvent> receivedEvents = eventHubConsumerClient.receiveFromPartition(
partitionId, 1, eventPosition);
The equivalent logic in V3 of the SDK worked fine (using PartitionReceivers), but now I am seeing OOMs in my JVM.
Running a profiler against a local version of the logic I see the majority of the heap (90%, mainly in OG) is being taken up by byte[]s, referenced by org.apache.qpid.proton.codex.CompositeReadableBuffer. This pattern is not present when I profile the V3 logic.
What could be causing a leak of the AMQP messages here, do I need to interact with the SDK further, for example close a connection that I'm not aware of after each call?
Any advise would be very appreciated, thanks!
Turns out it was a bug, solved here: https://github.com/Azure/azure-sdk-for-java/issues/13775

Azure: what could be the cause of the error "Unable to edit or replace deployment"?

When I recreate my VM I got the following error:
Problem occurred during request to Azure services. Cloud provider details: Unable to edit or replace deployment 'VM-Name': previous deployment from '8/20/2019 6:20:33 AM' is still active (expiration time is '8/27/2019 5:17:41 AM'). Please see https://aka.ms/arm-deploy for usage details.
Help me please to understand.
What could be the cause of the error ?
UPDATED:
This deployment has not been started previously.
Prior to this, errors were received during creation:
Azure is not available now. Please Try again later
There were several such errors one at a time and then I got that error related to:
Unable to edit or replace deployment
My assumptions about this.
Tell me, am I right or not ?
I launched the image, then after some time I recreated it.
Creation began, but at that moment the connection with Azure was lost.
Then, when the connection was restored, we tried to make a deployment that was not removed in the previous attempt (because there was no connection with Azure).
As a result, we got such an error.
Does this theory make sense?
exactly what it says, there is another deployment with the same name going on at this time, either change the name of the deployment you are trying to queue or wait for the other deployment to finish\fail
This can also occur if you use Bicep templates for your ARM deployement and multiple modules or resources in the template have the same name:
module fooModule '../modules/foo.bicep' = {
name: 'foo'
}
module barModule '../modules/bar.bicep' = {
name: 'foo'
}
I got the same error initially pipeline was working but when retriggered pipeline took more time so i canceled the deployment and made a fresh rerun it encounters. i think i need wait until that deployment filed.

How to inject a variable in threadlocal in spring integration flow

I need to inject a callContext object as thread Local in spring integration flow. A traceId which is received in jms header should be extracted n set in the callContext object so that it gets printed in log which is configured at project level.
IntegrationFlows.from(Jms.messageDrivenChannelAdapter(connectionFactory).destination(topicName))
.log(INFO, m-> “message received for: + ((Order)m.getPayload()).getOrderId())
.handle(orderService)
.get();
You can just do it in your orderService, or add another service just before it.
I would say a Function for log() operator provides you full control over what you would like to log in the message. Of course, also avoiding overhead with the ThreadLocal. But if you still would like to use it, I would suggest a .wireTap() before that log(), so you can store a value in your ThreadLocal (MDC?) without effecting the main flow.
Only the problem that you have to remember to clean that callContext somehow to avoid thread local pollution.

TeamCity Build Agent name is not picked up from config file

I have recently setup a VM on azure to use as my build agent.
When the agent is started its name is calculated based on the azure instance name (_myservername) and the name I provide in the buildAgent.properties file is ignored completely.
This is particularly problematic when I have a second agent and the same name is chosen which will result in name conflict.
looking at the teamcity-agent.log I can see the following lines:
[2016-07-14 15:33:04,745] WARN - ds.azure.AzurePropertiesReader - Unable to set self port. Azure integration will experience problems
[2016-07-14 15:33:04,745] INFO - ds.azure.AzurePropertiesReader - Added alternative address is set to
[2016-07-14 15:33:04,745] INFO - ds.azure.AzurePropertiesReader - Instance name and agent name are set to _myservername
...
Question is:
Why is the name I provide via config file is not taking precedence over any other place it reads the name from? -- should it?
How can I possibly force a name on it?
OK, the came to find the answer to this and would share it here in case it would be useful for the humans of the future!
The issue was caused by the the azure-plugin where it was setting a configuration-parameter on the agent called instance name.

The issue is fixed in the latest version of the plugin so upgrading it solved my problem. :)

Azure Document Db Worker Role

I am having problems getting the Microsoft.Azure.Documents library to initialize the client in an azure worker role. I'm using Nuget Package 0.9.1-preview.
I have mimicked what was done in the example for azure document
When running locally through the emulator I can connect fine with the documentdb and it runs as expected. When running in the worker role, I am getting a series of NullReferenceException and then ArgumentNullException.
The bottom System.NullReferenceException that is highlighted above has this call stack
so the nullReferenceExceptions start in this call at the new DocumentClient.
var endpoint = "myendpoint";
var authKey = "myauthkey";
var enpointUri = new Uri(endpoint);
DocumentClient client = new DocumentClient(endpointUri, authKey);
Nothing changes between running it locally vs on the worker role other then the environment (obviously).
Has anyone gotten DocumentDb to work on a worker role or does anyone have an idea why it would be throwing null reference exceptions? The parameters getting passed into the DocumentClient() are filled.
UPDATE:
I tried to rewrite it being more generic which helped at least let the worker role run and let me attached a debugger. It is throwing the error on the new DocumentClient. Seems like some security passing is null. Both the required parameters on initialization are not null. Is there a security setting I need to change for my worker role to be able to connect to my documentdb? (still works locally fine)
UPDATE 2:
I can get the instance to run in release mode, but not debug mode. So it must be something to do with some security setting or storage setting that is misconfigured I guess?
It seems I'm getting System.Security.SecurityExceptions - only when using The DocumentDb - queues do not give me that error. All Call Stacks for that error seem to be with System.Diagnostics.EventLog. The very first Exception I see in the Intellitrace Summary is System.Threading.WaitHandleCannotBeOpenedException.
More Info
Intellitrace summary exception data:
top is the earliest and bottom is the latest (so System.Security.SecurityException happens first then the NullReference)
The solution for me to get rid of the security exception and null reference exception was to disable intellitrace. Once I did that, I was able to deploy and attach debugger and see everything working.
Not sure what is between the null in intellitrace and the DocumentClient, but hopefully it's just in relation to the nuget and it will be fixed in the next iteration.
unable to repro.
I created a new Worker Role. Single instance. Added authkey & endoint config to cscfg.
Created private static DocumentClient at WorkerRole class level
Init DocumentClient in OnStart
Dispose DocumentClient in OnStop
In RunAsync inside loop,
execute a query Works as expected.
Test in emulator works.
Deployed as Release to Production slot. works.
Deployed as Debug to Staging with Remote Debug. works.
Attached VS to CloudService, breakpoint hit inside loop.
