@SimonAndréForsberg to be honest, don't have time to read all that :d

Simon André Forsberg

It's alright.

It is... quite complicated.

This question is probably the most complicated algorithm you'll ever see me put up for review.

Mat's Mug

@sim better put a real bounty on it then!

Simon André Forsberg

a real bounty?

what's a fake bounty?

Vogel612

@SimonAndréForsberg something like a measly 200 rep *wink wink*

Mat's Mug

I mean ^^^^ that

Simon André Forsberg

We'll see.

However, I have a feeling that if I would post a 500 bounty on it, that doesn't guarantee me an answer that's really worth 500. Perhaps the answer would be worth 100, or 250.

But I can't post a bounty on it for a couple of days anyway...

Mat's Mug

Even if you get an answer before then, it should be awarded a significant bounty ;)

Simon André Forsberg

Probably yes ^^

Depends on the quality of the answer

(a good worthy answer I mean)

Simon André Forsberg

What I'm mostly interested in is if there's anyone else who has done this before me, or if I'm the first to implement it.

I guess calculating detailed probabilities in Minesweeper is not something people do every day...

Q: Plus equal operator on an undefined variable produces NaN instead of the added value

Is there a way to use the plus equal operator as seen in the code below and produce 0 instead of NaN? var x; x += 5; x // NaN Is there a way to make this produce 5 instead of NaN? (What I'm saying is, is there a way to make it imply x is 0 instead of undefined without assigning x a value?)

Simon André Forsberg

Any spontaneous comments?

rolfl

11:34 AM

I don't like it when people extend HashMap ;-)

The deferred/buffer3ed hashCode is a problem too.

But, there is probably a good reason for it, so I figure I should look at the code more closely

but, I did read all the text, and decided the code would require a day to grok.

Simon André Forsberg

I'm not sure how much slower it would be if the hashCode would not be buffered.

rolfl

Well, not a day, but a few hours.

Simon André Forsberg

Yeah, it is complicated...

But hopefully you will also find it interesting :)

It is highly related to my other questions about combinatorics

rolfl

buffering the hashCode is not the problem, the problem is that it requires you to be disciplined to make sure you recalculate it when you need to.

there are some tricks you can do to avoid that, like a custom hashCode that is an XOR function, so you can recalcilate it with one operation each time you add a value.

and again when you remove a value.

Simon André Forsberg

I should perhaps use some more Immutable classes.

If I remember correctly, at the moment it gets constructed and then it stays that way.

rolfl

11:40 AM

int valcode  = val.hashCode();
int shift = valcode % 32;
valcode = (valcode >>> shift) | (valcode << (32 - shift))
hashCode ^= valcode;

Call that each time you add or remove a val.

it is naive, but effective.

Simon André Forsberg

Nice suggestion.

I'll go AFK for a couple of hours, visiting parents, be back later.

Dan Pantry

Question. What would you guys prefer -

public NetworkConnection(Stream stream, IPEndPoint address)

...

or

public NetworkConnection(TcpClient client)

RubberDuck

12:44 PM

One argument is always better than 2 IMHO

Dan Pantry

Well, the way I see it is that NetworkClient does not need the functionality of TcpClient

Jeroen Vannevel

What does the stream represent?

Dan Pantry

and by accepting a Stream, i can pass in a decorated Stream

Jeroen Vannevel

as in: what values could you pass?

Dan Pantry

Stream represents a bi-directional connection to the client

It would essentially be constructed like

var client = new TcpClient(...);
var stream = new DecoratorOrSomething(client.GetStream());
var connection = new NetworkConnection(stream, ...);

This lets me decorate my stream with a decorator that applies encryption

rather than have to tell the client "hey, you need to encrypt/decrypt this"

Vogel612

12:47 PM

I'd personally probably prefer the latter, but would expect an overload for the first...

or rather without the IPEndpoint...

Jeroen Vannevel

If you use the latter, how would you apply encryption?

Vogel612

because Streams can also need to be encrypted in non-network contexts.

@JeroenVannevel well you'd send it through the decorator before flushing.

Dan Pantry

@JeroenVannevel Pass in ICryptoTransforms into the Constructor and let the client decrypt encrypt it - which gives it more responsability

or have an IMessageEncoder that would be passed into the constructor of the client

It's that or decorated Stream

@Vogel612 I'd like to have the endpoint so consume the IP information of the connection elsewhere

IMO the NetworkConnection class should be a facade and thus not have to manage encryption decryption and so Stream should be decorated and accepted as a parameter

Just wondering what you guys would prefer if you came across the class in open source

(Java or C#)

Vogel612

so you'd go for something like:

Dan Pantry

EncryptedStream : Stream, IPAddress : IPEndPoint -> `NetworkConnection(Stream, IPEndPoint)

Vogel612

12:52 PM

NetworkConnection connection = new NetworkConnection(/*see overload of choice*/);
connection.setEncryptionStrategy(IEncryptionProvider);
connection.setStream(Stream);
connection.send(Packet);

Dan Pantry

Is my current solution, and I think that's the most idiomatic

@Vogel612 I really dont' like the idea of that

That's 3 mutators

NetworkConnection is concurrent - and is accessible throughout the application

It needs to present an API that won't modify it

Vogel612

then only allow setting them in the constructor...

Dan Pantry

Basically, I want that class to be immutable past construction.

What's the preferred constructor here - Stream, IPEndPoint or TCpClient

Vogel612

@DanPantry so like all fields final

Dan Pantry

That's my question :P

Vogel612

12:53 PM

but you want to decorate that with an Encryptor so the question is moot

also why not expose both?

Dan Pantry

Because I'm doing TDD and only writing what is necessary :P just wanted to know whether I was re-inventing the wheel by passing in a stream/address instead of just a socket

Vogel612

@DanPantry FWIW, if you just want network functionality, it would be dumb to expose a constructor taking a Stream...

Dan Pantry

@Vogel612 It is just for network functionality.

However, the added benefit as well with Stream is that I can mock a stream in C# - I can't mock TcpClient

we don't have cool stuff like Mockito in C#, the mocking framework I have limits me to mocking virtual methods on real classes, or interfaces

My other argument as well is that the NetworkConnection doesnt' need all of the functionality on TcpClient, just the Stream and it's IPEndPoint

I feel like this has been more like an interior monologue.. :p

Vogel612

cut -> class under test

skiwi

@Vogel612 You cut your new trainee?

Dan Pantry

@Vogel612 Yeah, I guess I agree. I'm wondering whether to make the type implement IObservable<T>, but that apparently violates the best use case of Rx

@Vogel612 Don't you mean UUT?

Vogel612

U != C??

Dan Pantry

No, but cut sounds like you injured someone :p

Vogel612

naaah...

Dan Pantry

1:34 PM

Let's say I alter my code I just wrote to something like this

using (var subscription = networkConnection.Read(5, mockObserver.Object))

read 5 bytes and notify the observer when it reads that many

5 could be omitted to read the maximum buffer size

thoughts?

Vogel612

that looks broken

that looks so extremely broken....

Dan Pantry

mockObserver.Object = Mock<IObserver<T>>

external library and is just for testing

using(var subscription = networkConnection.Read(5, myObserver))

in reality it would look more like

Vogel612

why would you allow Read(Int64 bytes, IObserver<T> observer)??

Dan Pantry

I was just offering alternatives to SubscribeRead

Hmm.. I'll think of something.

Vogel612

wouldn't you rather dispatch a readEvent ot all observers?

Dan Pantry

1:37 PM

I'm using something called ReactiveExtensions

which centers on the usage of IObserver<T> in place of dispatching events

IObserver<T> can be thought more alogn the lines of a 'stream' of data, rather than a stream of notifications

So IObserver<T> would be IObserver<byte[]> in this case, rather than IObserver<ReadEvent>

fk it. I'll just write a test suite and my usage of the class and post it for code review later

Vogel612

so the observer gets a copy of the actually "read" data??

Dan Pantry

@Vogel612 observer gets a copy of the byte array of read data, yes

Vogel612

public byte[] Read(Int64 bytes, IObserver<byte[]> observer)
{
     byte[] data = networkStream.Read(bytes);
     Observer.Stream(data.Copy());
     return data;
}

??

Dan Pantry

it would look more like this

public IDisposable Read(Int16 bytes, IObserver<byte[]> obs)
{
    return Observable.Defer(() => {
        var buffer = new byte[bytes];
        var offset = 0;
        return Observable.FromAsync(() => stream.ReadAsync(buffer, offset, buffer.Length))
            .Do(bytesRead => offset += bytesRead)
            .Select(bytesRead => { /* copy bytes */ })
    }).Subscribe(obs);
}

the returned IDisposable can be Dispose()d to 'unsubscribe' the observer from the observable

The whole chunk of code inside that method basically equates to "create a sequence that every time it is subscribed to will create a new byte buffer, and then run FromAsync and copy the byets into that buffer, and return it"

But thinking about it more, Read should return an IObservable because that allows you to compose stuff more. By returning IDisposable you are limiting the subscriber to do exactly as you say and not letting them compose stuff.. so I think I will violate the LoD here due to best practises of Rx

I'll psot a proper CR later. Maybe that'll give you more of an idea.

Simon André Forsberg

@firda As for whether or not you want to leave your comments there, that is up to you (although I bet @rolfl is scanning through them as we speak and might remove some of them). You may also flag Loki's comments if you feel that they should be removed for a specific reason.

Vogel612

(reasons include: offensive, too chatty, obsolete, not constructive and other)

firda

Well, I will think about asking him, that we both remove all the comments. He may be experienced, maybe he is too much experienced, that something that is obvious to him is not obvious to me. And searching in C++11 set by a key, that is not the value type is really not obvisou to me (I will either need C++14 enhancement, or some hack)

rolfl

@firda - I am struggling to understand both sides of the concerns here.

The base problem here is that the comments are not supposed to be a place to discuss strategies.

I think Loki is criticising your use of the preprocessor, and his review is not a comprehensive review of your application/code, just a subset of it.

I also see you suggesting he look in more detail at your code (and run things from links).

firda

The problem is under "Overdesign", he just states (no explanation), that the GetKey is never needed. That started it (I just asked). He made short comment and edited it. I was trying to get something positive, some meaning, std::map is the only think I can understand, std::set cannot be used (without GetKey or transparent less - which was added in C++14).

rolfl

2:45 PM

I can't debate the merits of his answer with you (I don't know C++ well enough).

What I can say though, is that objectively he appears to have reviewed your code based on what you presented.

Malachi

There are a lot of lowest voted questions that just need to be deleted..... let's use those moderation tools people

rolfl

It may not be a review you like, but it is a review.

It also does not appear to be offensive, or mean, or otherwise abusive.

Vogel612

seconding @rolfl here. The nice thing about this is: You can chose to ignore what he's saying If you have more information, than he has.

rolfl

It appears to be an earnest case of: you have things you don't need, you are leaking pointers, there are existing data structures that do that, and so on.

firda

It is ok he reviewed, the problem is I see his explanation-less statement as false and wanted to understand. That's all. Now he talks about my illusions. I must have angered him somehow (by I comment ended with: Of cours I can be the blind man)

@firda I cannot see any reference to 'illusions'.

I can understand that, but I am talking about his Overdesign and no need for GetKey. That is the point we talk about.

@firda: You asked me for a review. My review stands by itself. If you don't like it then ignore it. You seem to be under the illusion this is a competition were I am trying to win something. Its not; you asked my opinion I gave it. My role hear is not to make your life easier by providing you with answers to your questions, its to make you think about your mistakes so that you can improve. If you don't want to take advice then there seems little point in posting on the code review site. I will leave your questions alone in the future so that you don't feel threatened by my advice. — Loki Astari 1 hour ago
