DryIoc: Stackoverflow exception

I fixed it 👍 Stackoverflow is also gone. FEC LoadTest 17sec.
withoutFastExpressionCompiler LoadTest 21sec

Hi @Havunen

I have time Today to play with the LoadTest and wow! - this is an actual real-world usage scenario that DryIoc is needed to improve. 155 controllers - yay! So again - thanks for your work.

As of my test - 2nd and 3rd case are working for me. 1st is not and indeed throws a StackOverflow exception after a while. At the moment I am assuming the exception boils down to using FEC. Will try to track it down.

Thanks for the idea, but it didn’t work 😕

Its still crashing

Hi @havunen,

I had the typed Closure classes before with typed properties which look like that Closure<T1, T2... T8>. The problem is variation of property count, and anyway the fallback to the ArrayClosure at the end. Another problem is complexity where I need a conditional logic all over the place to load constants from the differrent closure types.

Regarding the number of instructions, it maybe solved by adding a method to access constant in ArrayClosure and emitting the method call. Will try it.

Btw, I did an experiment removing the Castclass in TryEmitConstant and it kind of worked, so will check other places to try the same.

Curry is no longer called in the branch, but SO is still here.

Did you see my tweets a min ago 😄 https://twitter.com/dadhi/status/1162447342366277633?s=19

Thanks a lot! How did you set a specific stack size?

Then I wanted to compare how much / what code Linq compiler emits and tried to use CompileToMethod. Unfortunately it failed to exception …

Unfortunately CompileToMethod can compile to static delegate only. That’s mean, no closure over non-literal values. Wich is not suitable for expressions produced by DryIoc.

I am currently fixing the issue with the shared closure in FEC to return to status quo. Then I will simplify logic in the ambient scope context - which is my current top suspect why SO hapens even without thread contention in Reduced load test.

Btw @dadhi I found something interesting today. Different compilation targets give different results:

Target Debug x86 - System.OutOfMemoryException AnyCPU - System.StackOverflowException x64 - Works

Target Release x86 - System.StackOverflowException AnyCPU - System.StackOverflowException x64 - -Works - Load Test Result – 00:05:06.48

Yes, I am playing both with compiled delegate and expression (sub-expression) cache.

The cache will be partitioned by service reuse:

• Singleton or Transient
• Scoped to specifically named or unnamed scope

Conditional request dependent services and decorators won’t be cached.

I debugged this further and realized its cycling between TryInterpret and TryInterpretMany always returning true and its going into NewExpression branch. I started tracking changes and noticed additional decorators were added quite same time this stackoverflow exception started occuring. I believe it has something to do with dependencies of decorators

Today this issue started happening in our development server, even without fast expression compiler.

new Container((rules) => 
    rules.WithoutFastExpressionCompiler().With(FactoryMethod.ConstructorWithResolvableArguments)
);

Here is crash dump:
