kestrelhttpserver's Issues

Active Keep-Alive connections are not closed before shutting down the loop

I'm currently tracking down ways the loop resource handle's Finalizer from #60 is called instead of the Dispose method.

One occurrence is when there are still active Connection: Keep-Alive connections that a browser could (and will) reuse. Those are still active handles on the loop and should be actively closed instead of implicitly through the shutdown logic.

Shutdown requests might free their memory before running the callback

UvShutdownReq's base class UvMemory only allocates a weak GC-handle. This means between creating the class in a Connection and having libuv running the callback method, it's free for collection and the Finalizer might run, which frees the memory

Libuv: For Unix OSes do not supply an exact path

The only supplied binaries for libuv are for WIndows and Mac. The Linux library would be libuv.so . I suggest to force Linux users to install a build of libuv themselves into one of the standard UNIX library paths and let the OS do the library finding when dlopen is called. This is because Linux runs on a multitude of different architectures most of which are supported by mono. Therefore it is not feasible for kestrel to try and supply a build for each CPU possible.

WriteAsync ReadAsync cancellationToken can't work

RequestAborted cancellation tokens not triggered for Kestrel

Example:

public class Startup
{
        static int count = 0;
        public void Configure(IApplicationBuilder app)
        {
            app.Run(async context =>
            {
                int requestId = count++;
                Console.WriteLine("Received request {0}", requestId);
                context.RequestAborted.Register(() =>
                {
                    Console.WriteLine("Cancellation token fired for request Id : {0}", requestId);
                });

                await context.Response.WriteAsync("Hello world" + requestId.ToString());
                await System.Threading.Tasks.Task.Delay(10 * 1000);
                await context.Response.WriteAsync("Finished writing" + requestId.ToString());
            });
        }
}

Host this application using Kestrel and make a request from IE or Chrome. Hit escape to notice that cancellation tokens are not triggered.

Shutting down issue on Mac OS

The normal way to shutdown Kestrel server is by pressing enter key. On OSX, if the user hits some other key, for example, 'Ctrl + C', the process is hung and cannot be exited. Pressing 'Ctrl+Z' stop the server but the port is blocked by the process. It would be great if the experience can be made better or at least have a default message that says' Press Enter to Exit"

Shutting the server down causes a hang

I ran the sample on osx using k run and then hit enter to quit the app after making a single request, it hangs forever

KestrelHttpServer should be able to create multiple libuv threads per process to better utilize CPU

Starting Kestrel host throws an exception on Win8 and lower OSes

I ran this command on windows 8 pro, windows 2008r2, windows 2012 configs. machines did not have VS installed. I saw following error

D:\Users\FWTLABB\.kre\packages\KRE-CLR-x86.1.0.0-beta1-10587\bin\klr.exe --appbase D:\TestMatrix\Dependencies\BugTrackerDesktopLv\src\BugTracker "Microsoft.Framework.ApplicationHost" Kestrel --server.urls http://localhost:5006

Running k kestrel should display the address and port that is being listened on

Exception in OnSendingHeaders not handled resulting in request hangs

Currently exceptions in OnSendingHeaders are not handled in Kestrel resulting in request hangs when an exception is thrown.

I ran into this issue with aspnet/Security#28. Kestrel in this case is resulting in a request hang.

Web socket support

Need to get managed-code web socket framing on once upgrade api is established

NullReference exception while shutting down Kestrel based application

I have seen this several times now on shutting down an application using Kestrel.

Unhandled Exception: System.NullReferenceException: Object reference not set to
an instance of an object.
   at Microsoft.AspNet.Server.Kestrel.Networking.UvHandle.ReleaseHandle()
   at System.Runtime.InteropServices.SafeHandle.InternalFinalize()
   at System.Runtime.InteropServices.SafeHandle.Dispose(Boolean disposing)
   at System.Runtime.InteropServices.SafeHandle.Finalize()

Launch the app, make a few requests to the server and after a while stop the app by pressing enter in the command prompt.

Parse names/ports from server urls

Right now it's using the constant port 4001

Improve data flows

Several places are doing array copies and growing-reallocations which should be an array of arraysegment of pooled byte[]... This relates to primary input/output data flows

Make Kestrel part of Universe

UvMemory should be Weak in several cases

Specifically the UvTcpStream used by Connection should be weak to enable it to collect.

This also means that some layer, the Uv types, or the Connection, will need to be able make a normal GCHandle to root the object graph while read callbacks are pending

RemoteIpAddress is not set by Kestrel

Currently, getting the IP address for a request when running on Kestrel yields nothing instead of the remote client's IP.

Object reference not set to an instance of an object when k kestrel on mono 3.8.1 on CentOS 6.5

I check the Home project, it says kestrel should support on mono, do I need install something on CentOS first ?

Returns 200 for unhandled exceptions

When the application throws an exception and it is caught by the server, Kestrel returns the current response as is. See Frame.ExecuteAsync(). It should send a 500 error response instead.

Expected behavior:

If the headers have been sent:
- Abort the connection
If the headers have not been sent:
- Set the status code to 500
- Clear the response headers
- Do not fire the OnSendingHeaders event
- Send the response

Have a notification on successful startup

When we run 'k kestrel' from the command line or shell, we need to wait for sometime for the server to start and then send the request.

The Musicstore starts kestrel server via code and there is no way for it see when the server has started unless we keep pinging the url for success. Can there be some kind of notification when the startup is successful like setting a variable or writing to a file ?

Null reference when running on osx

I tried porting https://github.com/davidfowl/HelloWorldVNext to only use kestrel and this is the error I get when trying to run k web on OSX:

Update libuv and automate build

Instead of installing the rc2 version of libuv, we should update to the latest 1.1.0 release:
https://github.com/libuv/libuv/releases/tag/v1.1.0

See aspnet/aspnet-docker#22 for a related PR

Connections leak when closed by the client

I'm currently tracking down ways the loop resource handle's Finalizer from #60 is called instead of the Dispose method.

One occurrence is when a Connection: Keep-Alive session is closed by the client instead of being reused.

Add tons of tracing

Need to figure out what xplat apis that should be based on.

Updated by Troy
Here's a task break down:

Logging swallowed exceptions
Optimize the Kestrel trace interface (optional)
Remove IKestrelTest interface.

Never Log request/response headers

This is not a binding

https://github.com/joyent/libuv/wiki/Projects-that-use-libuv

This is not a binding for C#, this is an application specific binding therefore it belongs in the category "Apps / VM".

k kestrel command on ubuntu 14 generates error

I build libuv from source and now libuv.so.1 is installed at /usr/local/lib.

Is there any step I am missing?

Reload app when file changes are detected

I'm playing with vNext + Nancy + OmniSharpSublime which gives me code completion, and I can start kestrel from within sublime.

What's not so cool is that the current version of OmniSharpSublime, fails to restart the kestrel server. Maybe this is by design, but wouldn't it be a nice option for kestrel to reload the code if it detects code changes? A bit like a grunt watch task?

Writing should use PostAsync to flow exception back to writer

FromIntPtr return null in UvShutdownCb

    private static void UvShutdownCb(IntPtr ptr, int status)
    {
        var req = FromIntPtr<UvShutdownReq>(ptr);

        req._callback(req, status, req._state);
        req._callback = null;
        req._state = null;
    }

req some times is null

Serving static files by default?

I've just been looking into serving some JS with Kestrel. I'm going to assume that I'll need to write a static asset middleware handler? Is there something built in already? I can't see anything.

Kestrel requires a TTY to stay alive, but should be daemonizable

See the blog post about Dockerizing ASP.NET and this issue aspnet/aspnet-docker#13 for context.

Kestrel should be able to be run as a daemon.

Why libuv ?

Hi,

I would like to have some information, why you use libuv instead of System.Net.Sockets ? What were your considerations ? I know, this is an issue tracker, but I'm really curious, what the drawbacks would be look like, when using the standard library.

Error running kestrel on a windows 8.1 machine with no VS

Not a mainline scenario, but gave a try running kestrel server on a windows 8.1 machine having no VS

---------------------------
klr.exe - System Error
---------------------------
The program can't start because MSVCR120.dll is missing from your computer. Try reinstalling the program to fix this problem. 
---------------------------
OK   
---------------------------

Calling close on wrong thread should be avoided

That can happen when a safehandle is GC'ed - to work this will actually need to queue to the loop handle to actually finish releasing?

kestrel doesn't allow me to get around firewall warning

One windows I can get around the firewall warning when listen on InetAddress.getByName(null) but kestrel doesn't give me a change to do so (

KestrelHttpServer/src/Microsoft.AspNet.Server.Kestrel/Http/Listener.cs

Line 73 in 6b2099d

ListenSocket.Bind(new IPEndPoint(IPAddress.Any, port));

Establish which ipv4/ipv6 socket addresses to open

Assumption is localhost should be ipv4+ipv6 loopback, numeric addresses should be that address in ipv4 or ipv6, and any other name including + and * should be ipv4+ipv6 any ip

NullReferenceException when running Kestrel against vNext project on Ubuntu 14.04 LTS

When attempting to launch a vNext site with Kestrel on Ubuntu 14.04 LTS, I receive a NullReferenceException:

System.NullReferenceException: Object reference not set to an instance of an object
  at Microsoft.AspNet.Server.Kestrel.Networking.Libuv.loop_size () [0x00000] in <filename unknown>:0 
  at Microsoft.AspNet.Server.Kestrel.Networking.UvLoopHandle.Init (Microsoft.AspNet.Server.Kestrel.Networking.Libuv uv) [0x00000] in <filename unknown>:0 
  at Microsoft.AspNet.Server.Kestrel.KestrelThread.ThreadStart (System.Object parameter) [0x00000] in <filename unknown>:0

In the project.json file for both projects, Kestrel is launched with the following command:

Microsoft.AspNet.Hosting --server Kestrel --server.urls http://localhost:5004

This occurs with my own codebase and the HelloMvc example in the Home repository. Is this a known issue that is resolvable?

Cheers!

IApplicationShutdown.RequestShutdown is does not serve the outstanding requests but dies

Related# aspnet/HttpSysServer#71

Send a request to the application. It is expected to serve the outstanding requests and die. This works as expected on Helios.

On Kestrel the event seems to be honored, but the outstanding request is not served. The host process simply gets killed.

On weblistener this event is not being honored. This item tracks the issue for weblistener: aspnet/HttpSysServer#71

public void Configure(IApplicationBuilder app)
 {
app.UseServices();
app.Run(async context =>
                {
                    Console.WriteLine("Received shutdown request...");
                    var appShutdownToken = context.ApplicationServices.GetService<IApplicationShutdown>();
                    appShutdownToken.RequestShutdown();

                    try
                    {
                        if (!appShutdownToken.ShutdownRequested.IsCancellationRequested)
                        {
                            await Task.Delay(10 * 1000, appShutdownToken.ShutdownRequested);
                        }
                    }
                    catch (Exception exception)
                    {
                        Console.WriteLine(exception);
                    }

                    if (appShutdownToken.ShutdownRequested.IsCancellationRequested)
                    {
                        await context.Response.WriteAsync("Shutting down gracefully");
                    }
                    else
                    {
                        await context.Response.WriteAsync("Shutting down token not fired");
                    }
                });          
  }

Add Kestrel to the ci server

How to exit?

Other than doing kill of course. Ctrl+C doesn't do anything.

KestrelHttpServer hangs when attacked with multiple requests, e.g. hit F5 multiple times in the browser

This is easy to reproduce with the samples - tested with MusicStore and HelloMVC on ubunto 14.04, Kestrel 1.0.0-alpha4 and latest libuv 1.0.0.x, compiled from sources.

Add keep-alive

I have tried kestrel and noticed that connections are closed immediately after returning data by using "Connection: close". Would it be possible to add keep-alive functionality to kestrel which would allow sockets to eb kept open and reused instead of doing expensive creates and closes everytime?

Show proper exception when libuv not installed or failed to be loaded

Because a null reference is really bad.

White screen of death on error

Hi,

I'm trying to develop an asp.net 5 website using Mono and Kestrel development server. When the website compiles properly, I'm able to load the website without any dramas on the local development port after launching k kestrel

However, if there is an error with my .cshtml view file (referencing wrong model), or even something as simple as a null reference exception error, the Kestrel web server just returns a white screen of death, without any explanation to the cause of the error, either on the webpage (like the traditional asp.net yellow error pages) or within the terminal running Kestrel.

Is there any way that I can determine what is causing the error? The null reference exceptions aren't too bad, by I'm unable to determine the error within my view.

Cheers,
Justin

Inconsistent package naming

Helios, WebListener, and Kestrel all use different package naming systems.

Kestrel:

Microsoft.AspNet.Server.Kestrel – The actual server
Kestrel – IServerFactory, Asp.Net feature interfaces, and a Program.Main that invokes Hosting.Program.Main (??).

WebListener:

Microsoft.AspNet.Server.WebListener – The IServerFactory & AspNet feature interfaces
Microsoft.Net.Http.Server – The actual server implementation

Helios:

Microsoft.AspNet.Loader.IIS - The IServerFactory & AspNet feature interfaces
(Several other assemblies for IIS interop)
There is a metapackage called Microsoft.AspNet.Server.IIS.

Recommendation:

Use the Microsoft.AspNet.Server.* for the components that directly interact with the web stack (IServerFactory, feature interfaces, etc.)
Use a product specific name for the package that contains the actual server implementation.
For Kestrel this would mean swapping the names of its two packages.
