I am trying to create an application that oversees message queues as they are processing messages.
To snapshot the message queue, i wrote the following code:
MessageEnumerator msgEnum = null;
try
{
// some code that fetches q (the queue)
msgEnum = q.GetMessageEnumerator2();
while (msgEnum.MoveNext())
{
Message current = msgEnum.Current;
Envelope msg = current.Body as Envelope;
// do something with the message
}
}
catch (Exception ex)
{
// handle exception
}
finally
{
if (msgEnum != null)
msgEnum.Close();
}
However, while another application is sending lots and lots of messages into the queue, i get the aforementioned exception.
I'm really confused as to why this is happening and what i need to do to make it work.
I also tried using GetAllMessages which resulted in the same exception.
Any help and/or explanations would be welcome.
edit:
the stack trace:

My postgres server version v12, Npgsql 7.0.0 used.
My question goes here: What's the status of DB Transaction on Postgres DB side, when Rollback a Npgsql.NpgsqlTransaction fails ?
And what's supposed to be done in that situation ?

I've been trying to make a build for Android with Unity, and I keep getting this error. I've reinstalled the Unity version and a few SDKs, but I can't figure anything out unfortunately. Any help would be appreciated!

When i lunch the app locally i check if no user exist then CreateAdminAccount creates an admin user.
Am sure the app cannot make any migrations before the app lunches in other to create the admin user.
I want to know how to apply the migration to the database when the app launches.

It appears that I am getting a few HttpRequestExceptions here.

You just need to keep digging. The exception "The response ended prematurely" isn't the root cause. Keep digging into the inner exceptions until you find the last one. You'll find this:
System.IO.IOException: Authentication failed because the remote party has closed the transport stream.
So it's not about your code. It seems the server you're hitting either can't handle the load, or is intentionally dropping your requests because you're hitting it too hard.
Also make sure the base address is correct
is it 'http' or 'https'
when you construct base address
In my case the problem was in the HTTP version. When I switched to HTTP/2.0 the exception was gone and the request completed successfully.
var message = new HttpRequestMessage(HttpMethod.Get, url) { Version = new Version(2, 0) };
var request = await httpClient.SendAsync(message);
I added the host and agent to the header, the problem was fixed.
var request = (HttpWebRequest)WebRequest.Create(url);
request.Host = request.RequestUri.Host; //"example.com"
request.UserAgent = "Dotnet";
In my case, a .netcore 3.1 application, it was solved by adding this line of code:
public void ConfigureServices(IServiceCollection services)
{
// Enable support for unencrypted HTTP2
AppContext.SetSwitch("System.Net.Http.SocketsHttpHandler.Http2UnencryptedSupport", true);
}
We had been successfully using the Microsoft ASP.Net Webhooks (specifically the Stripe one) in our WebAPI 2 project with Ninject. Recently we migrated to SimpleInjector and while everything else went well, we cannot get this webhook processor to work. It keeps throwing the following exception: System.MissingMethodException: 'No parameterless constructor defined for this object.'

Our global.asax looks like this:
var container = new Container();
container.Options.DefaultScopedLifestyle = new AsyncScopedLifestyle();
container.Options.PropertySelectionBehavior = new
InjectPropertySelectionBehavior();
// Register our stuff
container.RegisterMvcControllers(Assembly.GetExecutingAssembly());
container.RegisterWebApiControllers(GlobalConfiguration.Configuration);
container.Verify();
GlobalConfiguration.Configuration.DependencyResolver = new
SimpleInjectorWebApiDependencyResolver(container);
DependencyResolver.SetResolver(new SimpleInjectorDependencyResolver(container));
we're registering the WebHook handler like this:
container.Register<IWebHookHandler, StripeWebhookHandler>(Lifestyle.Singleton);
Has anyone gotten this to work with SimpleInjector? Or have any ideas what might be wrong?
Solution:
IWebhookHandler needs registered as a collection, so doing this:
container.Collection.Append(typeof(IWebHookHandler), typeof(StripeWebhookHandler));
instead of:
container.Register<IWebHookHandler, StripeWebhookHandler>(Lifestyle.Singleton);
was the trick!
I figured this out by stepping into the source of both the Microsoft Webhook assembly and SimpleInjector and found that when the Webhook assembly asked for all instances of type IWebhookHandler, SimpleInjector, in its GetServices implementation was trying to find all IEnumerable<IWebhookHandler> instead and so was coming up with nothing.
These kind of exceptions are thrown when trying to resolve a dependency that has parameter constructors but one or more of the parameters has not been registered and thus cannot be resolved, resulting in a fall back to a parameter-less constructor which in certain cases are absent.
Verify that you have registered all the components needed by WebHooks to work.
