Explore along with a strategy for durable functions in general.

For reproduce this error you simply can run Getting started example.

In current version we must set Content-type for all requests, but in case of GET methods when we produce request from browser Content-type are not added to headers request.

I have research the HTTP Protocol specification and googling should we set Content-type for all requests and TL;DR: Get requests should not have content-type because they do not have request entity (that is, a body)

I suggest to make the Content-type is not required. (At least for GET requests)

Repro steps:

1. Run https://functionmonkey.azurefromthetrenches.com/guides/gettingStarted.html this guide.
2. Run HelloWorld function from browser.

Error reason:

Looks like trouble in http.csharp.handlebars file in line
string contentType = req.ContentType.ToLower();

UPD: I can suggest a PR to fix this bug, but I don't have permissions to push.

Nice project, will write blog post on it when time allows.

I know that the docs say route parameters are not optional, but is this going to be a permanent limitation?

Hey James, I followed your blog post to setup a simple REST API, but getting this error when compiling:

MSB3073 The command "dotnet "C:\Users\engj.nuget\packages\compilecommandingfunctions\0.2.0-beta000\build\netstandard1.0....\tools\netcoreapp2.0/CompileCommandingFunctions.dll" C:\Users\engj\source\repos\Experimental\FunctionApp1\bin\Debug\netstandard2.0\bin\FunctionApp1.dll C:\Users\engj\source\repos\Experimental\FunctionApp1\bin\Debug\netstandard2.0" exited with code -532462766.FunctionApp1C:\Users\engj.nuget\packages\compilecommandingfunctions\0.2.0-beta000\build\netstandard1.0\CompileCommandingFunctions.targets9

Any ideas?

For example, the following code throws an exception at build in FM.Compiler.

public interface ICustomCommand<T>: ICommand<T> { } // some custom stuff
public class MyFooCustomCommand: ICustomCommand<Foo>

The code throwing the exception is:

Type genericCommandInterface = CommandType.GetInterfaces()
.SingleOrDefault(x => x.IsGenericType && commandInterface.IsAssignableFrom(x));

Because the GetInterfaces() is returning ICommand<Foo> and ICustomCommand<Foo>.

It seems you are looking for just ICommand<Foo> in this case. Since this is at compile, you could narrow it down by adding a check on the interfaces for x. ICommand<Foo> will only have the one so && x.GetInterfaces().Count() ==1 would work (since you are already checking IsAssignableFrom(x)).

Thoughts?

Hello

I am trying to get the connection string through IOptions.

builder
.Setup((serviceCollection, commandRegistry) =>
{
serviceCollection.AddLogging();

                //serviceCollection.AddOptions();

                serviceCollection.AddOptions<DbSettings>("DbSettings");

....
....

DbSettings is defined in local.settings.json.

However, when I access this through the constructor of the command handler, the value is coming as null.

Any help is appreciated.

Thanks
Kris

How do you control the return status code from a HTTP trigger, eg: when a resource is not found and you want to return a 404? There doesn't seem to be anything on the Contextprovider to use here. And from looking at the templates in the source code, returning a HTTPResponseMessage from your handlers seems to be a no no?

public class GetEventByIdHandler : ICommandHandler<EventQuery, EventModel>
    {
        private readonly DBContext _context;
        private readonly IContextProvider _provider;

        public GetEventByIdHandler(DBContext context, IContextProvider provider)
        {
            _context = context;
            _provider = provider;
        }

        public async Task<EventModel> ExecuteAsync(EventQuery query, EventModel previousResult)
        {
            var @event = await _context.Events
                .Where(x => x.EventId == query.Id)
                .BuildEventModel()
                .FirstOrDefaultAsync();

           //If Event is null return 404

           return @event
        }
    }

I also have that helloworld example from your blog which is working fine but not this one. Error message is also not helpful because I have namespaces, classes and methods created correctly.

skeptical about the name I have now created a new project without dash in its name . azdeployerapi. it has the same configuration, command and command handler files inside it. This one builds succesfully without any issue. so I guess having dash (-) in its name is causing a project not to build. Please look into it.

Triggered by discussion in #41

I have been attempting to work with entity frameworks cosmos provider and function monkey.

Hi

First of all, thanks for the effort putting up something useful.

When following the examples provided here, the sample code provided for the following code snippet will not compile. The variable 'name' does not correspond to a corresponding variable, hence the error.

How can I rectify this?

Hi there,

I've been testing Function Monkey on a new project and I think it's great. However, I've run into an issue a couple of times now when trying to incorporate some Cosmos DB stuff. I managed to resolve it the last time by changing package versions, but thought I'd post it this time as I'm struggling to get past it this time. Not sure if you can help.

Hello
Thank you for this library, it is really useful and really appreciate this.

I would like to know whether the framework allows to have my own CreateResponse method.
Mainly, we are using SnakeCaseNamingStrategy instead of CamelCasePropertyNamesContractResolver for the JSON.

public static IActionResult CreateResponse(int code, object content)
{
ContentResult result = new ContentResult();
result.Content = JsonConvert.SerializeObject(content, Formatting.Indented,
new JsonSerializerSettings {ContractResolver = new CamelCasePropertyNamesContractResolver()});
<-- can this be SnakeCaseNamingStrategy()
result.ContentType = "application/json";
result.StatusCode = code;
return result;
}

Our ASP.NET Core MVC is using:

services.AddMvc(config => {
config.Filters.Add(typeof(CustomExceptionFilter));
}).AddJsonOptions(opts =>
{
opts.SerializerSettings.ContractResolver = new DefaultContractResolver
{
NamingStrategy = new SnakeCaseNamingStrategy()
};
opts.SerializerSettings.NullValueHandling = NullValueHandling.Ignore;
}); ;

Thanks
Kris

After I updated to 0.18.6 which fixed all my other problems, my VSTS build started failing. Im using the standard function app deployment template which does a build and publish.
I noticed that it passed running the 'after build' compile, but failed the 'after publish' compile with the error:
FunctionMonkey.ConfigurationException: CS1705:Assembly 'FunctionApp3' with identity 'FunctionApp3, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' uses 'System.Runtime, Version=4.2.1.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' which has a higher version than referenced assembly 'System.Runtime' with identity 'System.Runtime, Version=4.1.2.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' SourceFile([3106..3147))
I get the same error running the dontnet command from the command line.

After some digging I saw that in FunctionMonkey.Compiler.targets, you are differentiating the FunctionCompilerParams for dotnetcore and adding --netcore21. That is not being done for FunctionPublishParams.

Adding that flag to the command line seems to fix the error, but I don't have a way to do that from my VSTS build.

Sorry James,

Get this when i upgrade to latest 0.18, rolling back to 0.17 works.

Let me know if you need anything else to help debug

After a bit of digging around, I found that inside of netstandard1.0/FunctionMonkey.Compiler.targets I was specifying this path with:

    <FunctionCompilerExe Condition="'$(TargetFrameworkIdentifier)' == '.NETCoreApp' OR '$(TargetFrameworkIdentifier)' == '.NETStandard'">dotnet "$(MSBuildThisFileDirectory)..\..\tools\netcoreapp2.0\FunctionMonkey.Compiler.dll"</FunctionCompilerExe>

Surprisingly, the direction of those slashes was actually important - when I reversed them, I located the DLL correctly (I verified in the terminal that it was in fact at that location too)

    <FunctionCompilerExe Condition="'$(TargetFrameworkIdentifier)' == '.NETCoreApp' OR '$(TargetFrameworkIdentifier)' == '.NETStandard'">dotnet "$(MSBuildThisFileDirectory)../../tools/netcoreapp2.0/FunctionMonkey.Compiler.dll"</FunctionCompilerExe>

However, this might of fixed that issue but it uncovered a much more troublesome issue that I can't fix.

If you need any details I will happily provide. I am building a production system using this platform as I actually was going to build all of this myself before I stumbled upon the framework thanks to a tip from a mate (how lucky!!!).

Happy to help however I can! The only potential thing I can think of is that my DLL resides within netstandard2.0, while FM.Compiler seems to be in netstandard1.0?

No job functions found. Try making your job classes and methods public. If you're using binding extensions (e.g. Azure Storage, ServiceBus, Timers, etc.) make sure you've called the registration method for the extension(s) in your startup code (e.g. builder.AddAzureStorage(), builder.AddServiceBus(), builder.AddTimers(), etc.).

Azure Functions Core Tools (2.3.199 Commit hash: fdf734b09806be822e7d946fe17928b419d8a289)
Function Runtime Version: 2.0.12246.0

Forked the repo and added as existing projects then created reference built and played.

This is because I wan to update the microsoft azure document db core library and potentially the microsoft extensions dependency injection library.

Looks like I only have function monkey compiler 0.18.6-beta000 but my nuget package is 0.18.7-beta000. Not sure how to update my codes.

Header Mapping doesn't work as expected.
I want to bind my Authorization header to command property, in order to do this I use the following construction.
.HttpRoute("/Invoice", route => route
.HttpFunction(HttpMethod.Get)
.Options(options => options.AddHeaderMapping(x => x.Authorization, "Authorization"))
)

And this Authorization property always null.

Do you have any suggestions on why it can not work?

I've created a simple program to demonstrate it.
There is the following enum.

public enum SortOrder
{
Ascending = 1,
Descending = 2
}

and command:

public class EnumCommand : ICommand<string>
{
public SortOrder Order { get; set; }
}

For all requests below, the Order field is alwayws 0.

http://localhost:7071/api/Enum?Order=Descending
http://localhost:7071/api/Enum?Order=Ascending
http://localhost:7071/api/Enum?Order=1
http://localhost:7071/api/Enum?Order=2

Do you have any suggestions why this doesn't work?

Hello again!
It appears the compiler is playing up again. At this point, I have finished coding the system and have gone to start my debugging & testing.

It was compiling and working fine right up until I reference Netwonsoft throughout some models to make sure the JSON Serialisation process succeeded correctly (well, it could have happened before then, but that was the latest change before I attempted to build it again).

Then, when I went to run unit tests, I get:

Which is a gleefully large error message that seems to be just saying that it can't find Newtonsoft.

Which is troubling, as I have 11.0.2 installed across the platform and it is referenced from multiple dependencies as well. I have tried clearing the bin & obj, restoring, reinstalling Newtonsoft, downgrading Newtonsoft, ect...

But with no success.

Let me know if there are any other details you require,
Cheers,
Adam.

I get this when trying to use FunctionMonkey with the following assemblies

Cosmonaut v2.9.0
Microsoft.Azure.DocumentDB.Core v2.2.2
Microsoft.Azure.WebJobs.Extensions.CosmosDB v3.0.3
Microsoft.Azure.WebJobs.Extensions.SignalRService v1.0.0-preview1-10025
Microsoft.NET.Sdk.Functions v1.0.24

I believe this is related to a assembly version conflict with the Microsoft.Azure.DocumentDB.Core assembly and I am unable to downgrade due to the other package that I am using

Any ideas when you can bring the references more up to date?

The Azure Functions Service Bus and Storage Queue triggers have no sense of back off - so if you have a service bus message who's handler is failing (perhaps because a call to an external resource is failing) it gets pulled back through almost immediately - you can effectively end up "hammering on the door" of the external resource until the max retry count is reached.

A technique I've used to deal with this is to post a new message onto the service bus queue but with the enqueue visibility set to n seconds time and then allow the original message to be removed.

I'm considering codifying this in Function Monkey through an option on these trigger types.

Feedback welcome.

I didn't see anything in the samples where an ILogger can be added to the DI Container. I am aware that the Functions runtime does this by default but can you provide direction on how to configure for handlers and commands, etc.?

I am looking to get hold of the form object from the HTTP request (reqest.Form.Files)to be able to get a file that is being sent to a function. We currently get this through the request in the function call and im unsure on how to map this to a Command. Help appreciated!
Thanks

First. I love this project!

I dont know if I am doing something wrong, or missing something, but:
When I try to compile with timer or queue functions, it fails during the FunctionMonkeyCompiler, complaining: The type or namespace name 'ValidationException' does not exist in the namespace 'FunctionMonkey.Abstractions.Validation'. I searched through the repo and found that class in FunctionMonkey.Commanding.Abstractions.Validation (Commanding added), pulled, changed the templates and recompiled.

timer.csharp.handlebars
servicebusqueue.csharp.handlebars
servicebussubscription.csharp.handlebars
eventhubqueue.csharp.handlebars
storageblob.csharp.handlebars
storagequeue.csharp.handlebars

That error went away, but then it started complaining about messageId not being found. It seems messageId made it into some of the validation exception messages where it wasnt defined in the method signature.

timer.csharp.handlebars
eventhubqueue.csharp.handlebars
storageblob.csharp.handlebars
storagequeue.csharp.handlebars

Currently the Function Monkey compiler runs as a console app invoked via a target in the MSBuild chain. When an error is encountered it throws out an exception that gets logged in the output window but its really less than ideal - on Mac or Linux you can also end up with a system style dotnet exception.

I'd like to wrap the compiler in an MSBuild task that better integrates into the build chain.

https://docs.microsoft.com/en-us/visualstudio/msbuild/task-writing?view=vs-2017

Not something I've done before, if anyone has any best practice or hints and tips I'd love to hear them.

Following your recent Part 1 video on using FunctionMonkey and once I have a simple structure created to verify the plumbing works, I get the following error:

Have you seen this before?  Both macOS w/ VS Code and VS 2017 enterprise get the same result.  Debugging does not seem to get past some of the Function framework prices, or maybe I am missing a way to debug into the actual issue.  

I'll keep digging, but thought I would ask if this might be something simple.  

I was follwing steps in this tutorial. I tried the build the app and I ended up with error.

I am using FluentValidation in my project.
I have created my own IHttpResponseHandler and i have noticed that ValidationResult can't be overridden because generated code doesn't call it.

Should be able to expose (or reuse) the functionality FluentValidation has on ASP.Net

Currently every function type needs a connection string setting name specifiying. Aim of this change is to keep those functions but allow defaults to be provided (and overridable).

Hi James

Thanks for building this framework, appreciate the effort and good thinking.

I have a question regarding Auditing ability shown in this article.

I presume that I need the ICommandingDependencyResolverAdapter resolver or ICommandRegistry registry so I can add the Pre, Post and Execute Dispatch hooks. Is there a way that I can do it in FunctionAppConfiguration currently?

Thanks!

Hello

Do you mind, turning off the CamelCasePropertyNamesContractResolver() in method - CreateResponse in the file: http.csharp.handlebars?

So that we can change the JSON.NET default DefaultContractResolver to apply a different behavior for all the API.

After merging PR today output Function cs file has error. For example:

            Microsoft.Extensions.Primitives.StringValues queryParameterValues;
            string method = req.Method.ToUpper();
            if (method == "GET" || method=="DELETE")
            {
                        if (req.Query.TryGetValue("Id", out queryParameterValues))
                        {
                            {
                                {
                                    System.Nullable<System.Guid> nullableValue;
                                    if(TryParseNullable(queryParameterValues[0], System.Guid.TryParse, out nullableValue))
                                    {
                                        command.Id = nullableValue;
                                    }
                                }
                            }
                        }
                        if (req.Query.TryGetValue("Name", out queryParameterValues))
                        {
                            command.Name = queryParameterValues[0];
                        }
                        if (req.Query.TryGetValue("Order", out queryParameterValues))
                        {
                            {
                                FunctionApp1.SortOrder result;
                                if (System.Enum.TryParse<FunctionApp1.SortOrder>(queryParameterValues[0], out result))
                                {
                                    command.Order = result;
                                }
			}

            }

It seems that missed "}" at last line

This essentially boils down to allowing a function name (and the class name in the template) to be either user specified or generated using more than just the type name.

At present the http.csharp.handlebars template only sets up the Context Setter just prior to executing the Command. It would be extremely useful to have access to the Context from inside the ITokenValidator.ValidateAsync method.

If we moved the code that sets the Execution Context (currently line 118) to an earlier point (say Line 40) then the execution context would be available to all the code that runs from there on out .

Hi James. I've cloned the full FunctionMonkey solution locally and have set GettingStartedSample project as the startup project. I've done no other modifications to the source code and configuration. When running the project I get the following message in the function runtime terminal (version 2.0.12134.0):

"No job functions found. Try making your job classes and methods public. If you're using binding extensions (e.g. Azure Storage, ServiceBus, Timers, etc.) make sure you've called the registration method for the extension(s) in your startup code (e.g. builder.AddAzureStorage(), builder.AddServiceBus(), builder.AddTimers(), etc.)."

As a result no URL is provided for running the application. Could that be related to the changes in the Functions runtime since the latest version of FunctionMonkey was released?

How can I set up a function that will download a Zip file to the client when completed?

I have a function that will generate multiple PDF documents and would like to return a Zip file container each of the created PDF documents to the client, do you have any examples?

Thanks for the framework, love and keep up the good work.

I have a question though about how to add SignalR input binding to a function, for example if I create a standard function I can add [SignalR(HubName = "assessments")] IAsyncCollector<SignalRMessage> signalRMessages in the function which then allows me to send events using WebSockets

I cannot seem to find a way to do this with FunctionMonkey, if I add this to the ExecuteAsync method I get a compile error

For example allow 6 service bus queues to be associated with a single command by providing an array of queue names

A prereq to this is #53

Somewhat inspired by Azure/azure-functions-host#4234
