csharp-driver's Issues

Failure with the exceptions test

Code:

class Program {
    static void Main(string[] args) {
        int a;
        try {
            a = 1;
        } catch (System.Exception ex) {
            a = 2;
        } finally {
            a = 3;
        }
    }
}

Result:

--- FAIL: TestCsharpDriver (3.26s)
    --- FAIL: TestCsharpDriver/semantic (1.14s)
        --- FAIL: TestCsharpDriver/semantic/exceptions (0.03s)

Missing OS column val in the driver list table

A nitpick on the driver manifest most probably, but right now it looks like:

Failure with a simple test

(adding it as an issue to not block the current PR)

This code:

class Program {
    static void Main(string[] args) {
        while(true) {
            break;
            continue;
            goto Finish;
Finish:
    }
}

gives this error when trying to generate the integration test fixtures:

--- FAIL: TestCsharpDriver (3.22s)
    --- FAIL: TestCsharpDriver/semantic (1.11s)
        --- FAIL: TestCsharpDriver/semantic/flow_break (0.02s)

        			Error:      	Received unexpected error:
        			            	check: key "Identifier": field was not used: IsMissing

It also happens with some other tests, but this one is the simpler.

Native driver crashed

From bblfsh logs we got a message of rpc error native driver crashed. Example of files that triggered this error:

HtmlFragmentHelper/Program.cs

Driver does not support comments

The current implementation does not produce any comments in the native AST. Should find a flag to enable it.

Can't get value of csharp:InterpolatedStringText node

I have this code:

namespace SomeNamespace
{
    public static class SomeClass
    {
        public static String GetFromFoo(field String)
        {
            return " SELECT " + param + " FROM foo";
        }
      
      	public static String GetFromFooWithInterpolation(field String)
        {
            return $"SELECT {param} FROM foo";
        }
    }
}

This query returns the " SELECT " node:

//csharp:BinaryExpression_AddExpression/Left/uast:String[string-length(@Value) > 0]

However, this does not return the $"SELECT " node:

//csharp:InterpolatedStringExpression/Contents/csharp:InterpolatedStringText[1]/TextToken[string-length(@Value) > 0]

Even though I can see inspecting that it does have a Value attribute.

So far, it only happens with that node.

Blacklisted `IdentifierName` found in test

        --- FAIL: TestCsharpDriver/semantic/generics (0.09s)
        	fixtures.go:288: blacklisted nodes of type "IdentifierName" (1) found in the tree
        	fixtures.go:318: no test file found - generating

Happens with the tests generics.cs (generics.cs.bug in the current PR).

Driver doesn't start

I use bblfshd v2.11.4 and csharp-driver v1.2.0.

To reproduce the bug I use this simple program:

package main

import (
	"context"
	"fmt"
	"time"

	bblfsh "gopkg.in/bblfsh/client-go.v3"
)

const code = `// A Hello World! program in C#.
using System;
namespace HelloWorld
{
    class Hello
    {
        static void Main()
        {
            Console.WriteLine("Hello World!");

            // Keep the console window open in debug mode.
            Console.WriteLine("Press any key to exit.");
            Console.ReadKey();
        }
    }
}`

func main() {
	client, err := bblfsh.NewClient("127.0.0.1:9432")
	if err != nil {
		panic(err)
	}

	go func() {
		started := time.Now()
		for {
			time.Sleep(time.Second)
			fmt.Println("Time since request started", time.Now().Sub(started))
		}
	}()

	_, _, err = client.
		NewParseRequest().
		Context(context.Background()).
		Language("csharp").
		Content(code).
		UAST()
	if err != nil {
		fmt.Println(err)
	}

	fmt.Println("success")
}

$ go run bblfsh_csharp.go
Time since request started 1.004217185s
...
Time since request started 5m3.852441925s

there are no logs on the server side except when I Ctrl-C the program:

[2019-02-06T12:27:00Z]  WARN unable to allocate a driver instance: context canceled language=csharp
[2019-02-06T12:27:00Z] ERROR request processed content 341 bytes error: context canceled elapsed=5m4.8500838s language=csharp

I see this processes in the container:

I/O timeout

From bblfsh logs we got a message of rpc error read |0: i/o timeout. Example of files that triggered this error:

sdk/src/Services/KeyManagementService/Generated/_bcl45/IAmazonKeyManagementService.cs
tests/src/JIT/Directed/cmov/Float_Xor_Op.cs
tests/src/JIT/Directed/cmov/Int_And_Op.cs

Handle syntax errors properly

Currently, the driver does not handle the syntax errors as it should. We need to add a fixture that tests for parsing errors and implement error handling in the native driver.

Parsing a file rise a panic

discovered at https://github.com/src-d/empathy-sessions/issues/37#issuecomment-470045137

might be related to #27
causes bblfsh/bblfshd#259

While using bblfsh/bblfshd:v2.11.8 image (the current latest), and parsing a csharp file I discovered that it screwed the bblfsh container up, and it won't be able to accept new parse requests.

here is how to reproduce the bug:
