EBrown

Hosch250

Can you check this query? data.stackexchange.com/codereview/revision/590654/740358/…

I want to find too broad questions.

If that is correct, we have 11 questions that are too broad that haven't been reopened.

EBrown

It probably is correct.

Hosch250

OK.

EBrown

We don't use "Too Broad" all that often.

Hosch250

3:39 AM

I know.

EBrown

I don't have mod tools anymore, so I can't verify.

Hosch250

That's what my meta question is going to be about.

I think we should use it for Gimme teh Codez questions.

Maybe, that is.

That is because they don't really fall into "Asking advice about code not yet written."

They aren't asking for advice at all--they just want the code.

EBrown

GRAH THIS THREADING STUFF IS NOT WORKING AT ALL

Hosch250

You see, we could use ^, or we could use "No code in question," or "Too Broad."

EBrown

It never removes my thread.

Hosch250

3:42 AM

I think TB would be the best fit, so I'm going to toss my argument before the site.

@EBrown Which lang?

EBrown

@Hosch250 C# of course.

Tasks are being dumb.

Hosch250

If you are using .NET, then just use the TPL.

The task will remove itself when it is finished.

EBrown

I am, they're not working.

It's not supposed to complete, is the thing.

Hosch250

In fact, just because you use a task doesn't even mean it creates a new thread.

EBrown

It's an infinite loop for a WPF GUI.

Hosch250

3:43 AM

GAHHHHHHAHAHAHAHAHAH

EBrown

The problem is that I am trying to "cancel" it without a cancellation token, and then detect when it cancels.

Hosch250

Never use infinite loops for GUI's, especially not in WPF.

EBrown

It's not for the GUI

Hosch250

Use events and commands.

EBrown

It's a simulator for something, but it reflects information into the GUI.

It works as expected, the problem is that I need it to cancel when I set a specific boolean flag.

Hosch250

3:44 AM

Hey there, @Mehrad!

EBrown

And it is, but the TPL isn't reporting it correctly.

Hosch250

Long time no see!

EBrown

Then I tried throwing an ArgumentException and that didn't work.

Hosch250

@EBrown Are you using the cancellation token correctly?

EBrown

@Hosch250 I'm not using a CancellationToken.

Hosch250

3:45 AM

Then I'm not surprised.

You need to pass a cancellation token into the thread and cancel it from outside the thread.

That's the C# way of doing it.

Or whatever you are doing.

You can cancel it anywhere you can control the token source, really.

EBrown

Well I'm trying to do it slightly different, and .NET is being entirely illogical about it.

Mehrad

@Hosch250 Good to see ya @Hosch250. Pretty busy with some C stuff and don't get to meet the old friends much :D

Hosch250

Nice.

EBrown

_task = Task.Factory.StartNew(() => Run().Wait());

Mehrad

Atm the moment dealing with some stack overflow :/

EBrown

3:47 AM

Then, inside Run, some of the code:

        private async Task Run()
        {
            var waitSw = new Stopwatch();

            while (_runTask)
            {
                // Some stuff
            }

            _taskFinished = true;
            throw new ArgumentException("Cannot run task when {nameof(_runTask)} is false.");
        }

Then I have a Clear method:

Hosch250

Uh, what?

You are making a task that is a field?

EBrown

public void Clear()
{
    while (!_taskFinished)
    {
        _runTask = false;
        Task.Delay(25).Wait();
    }

    _taskFinished = false;
    _runTask = true;
    _task = Task.Factory.StartNew(() => Run().Wait());
}

The problem is that the clear method is entering an infinite loop.

Because _taskFinished never get's set.

Hosch250

I'm pretty sure that isn't a very good idea.

EBrown

I thought about using the Task.Status property, but that doesn't work properly either.

It still shows Running instead of RanToCompletion.

Hosch250

Yeah.

You are never finishing the task.

.NET is working 100% right.

You need to kill the bloody task.

EBrown

3:50 AM

No, it's not.

It's working entirely wrong.

I have killed it

It's had a chance to die a million different ways.

It refuses.

Hosch250

No you haven't.

EBrown

The loop finishes.

The TPL registers the exception.

Even without the exception the TPL registers that the task finished.

The problem is that the TPL never let's me see that it finished.

Hosch250

Then the Task.Status won't be Running.

EBrown

But it is.

Hosch250

Also, why the heck are you restarting it after you clear it?

EBrown

3:52 AM

Don't worry about that.

That's intended.

Hosch250

OK.

Umm, I don't even see how you can even get the task to run.

while (!_taskFinished)
{
    _runTask = false;
    Task.Delay(25).Wait();
}

Look.

EBrown

Yes, and then right after that _taskFinished = false; _runTask = true;.

Hosch250

Oh, nvm.

EBrown

Then I recreate the task.

Hosch250

I thought you were delaying the running task.

EBrown

3:53 AM

Inside the task it only does things if another field is > 0.

Hosch250

Well, I tell you you are doing it wrong.

This is what you really want:

First, set the field and start the task.

EBrown

The problem isn't what is/isn't the best way, the problem is that .NET is not doing what it should.

Hosch250

Second, use the .OnCompletion() method to restart it.

EBrown

I just ran a few tests, and .NET doesn't register the exception being thrown sometimes.

Hosch250

Just wait a second.

You have a race condition.

EBrown

3:56 AM

75% of the time the debugger throws on the Task.Factory.StartNew(... line that created the task, but 25% of the time it doesn't finish.

Hosch250

_taskFinished has a race condition.

This code is so bad I don't even know where all your bugs are.

Just do it the right way the first time.

EBrown

"The code is so bad" bs.

You're not seeing what I'm seeing.

Hosch250

Maybe that's because I have a fresh look.

EBrown

No, you aren't seeing it in action.

Hosch250

@EBrown Maybe I'm seeing bugs you aren't. And please use Tasks correctly.

And if you think .NET has a bug, then contact the .NET team. I can't help if it is a .NET bug.

EBrown

4:04 AM

I give up.

Hosch250

OK, feel free to weigh in on my meta question.

Maybe I should have waited for Winter Bash. It would be a good one for hats, I think.

EBrown

CancellationToken isn't working either.

Hosch250

Are you using continuations?

EBrown

???

Hosch250

Use .ContinueWith to restart the task.

It will run each time the task completes.

EBrown

4:11 AM

I won't want to restart it yet.

It doesn't cancel yet.

python algorithm

EBrown

_cancellationTokenSource.Cancel();

while (_task.Status == TaskStatus.Running)
{
    Task.Delay(25).Wait();
}

It's still TaskStatus.Running even after cancelling.

You have got to be kidding me...

Hosch250

The task status should be TaskStatus.Cancelled.

EBrown

It's not.

Hosch250

Also, are you passing the token into the task correctly?

EBrown

4:15 AM

Yes.

It works 7/10 times.

Hosch250

Task.Run(() => {}, token)

EBrown

I changed the while to while (!_cancellationToken.IsCancellationRequested) and it's still not completing.

But the while loop also isn't looping.

Hosch250

Then, you need to call token.ThrowIfCancellationRequested().

I'm not sure if you call that periodically or just once.

It looks like you call it periodically.

EBrown

You don't need to call that at all.

Hosch250

Oh, right.

EBrown

4:17 AM

It's not throwing anyway.

Hosch250

@EBrown It sounds like you have a race condition to me.

EBrown

I CAN'T

Hosch250

Odds are you do.

EBrown

Unless the CancellationToken itself has a race condition.

I changed the entire code.

Hosch250

Do you access any variable from both threads?

EBrown

4:18 AM

Yes, but it can't be causing this issue.

Hosch250

I've done enough multithreading in RD's parser to be very suspicious.

EBrown

There's no way in hell that it can.

Hosch250

You might be surprised. I was.

You can always make an SO post.

Incoming off topic--no code.

EBrown

It's got to have something to do with the await in the Task.

Hosch250

Probably.

Uh, why are you awaiting in a task?

EBrown

4:21 AM

I'm not.

Hosch250

@EBrown Then what does thus mean?

EBrown

await Windows.ApplicationModel.Core.CoreApplication.MainView.CoreWindow.Dispatcher.RunAsync(Windows.UI.Core.CoreDispatcherPriority.Normal, () => Generation++);

That's a LoC in my Run method.

Looks like that's creating the issue.

Hosch250

Exactly.

That is booting up a third thread within the second thread.

EBrown

That makes no sense.

Hosch250

Yes it does.

That's what await calls do.

EBrown

4:23 AM

Please explain.

Because as far as I'm concerned it makes 0 sense.

Because everything else is working as expected.

Hosch250

async methods create a new thread to run the method in.

When you do an await call, it boots up a new thread because you are calling an async method.

EBrown

I know that.

But that does not at all explain why it's causing this issue.

Hosch250

When the async method returns, it continues from where you were with one of those continuations I mentioned.

No, I'm confused too.

Basically, your code looks like this:

EBrown

I think I figured it out.

As soon as I say that I'm wrong.

Hosch250

Task.Run(() =>
{
    // run code...
    await ...
    Task.Run(() => {async method body})
        .ContinueWith(() => { rest of method body });
}

Anyway, are you using C# 7?

EBrown

4:27 AM

No

Hosch250

OK.

Because they made some changes in that.

Hosch250

Huh?

EBrown

Don't use await or .Wait() on the "third" task.

Hosch250

4:37 AM

Hmm.

EBrown

var t = Task.Run(() => Windows.ApplicationModel.Core.CoreApplication.MainView.CoreWindow.Dispatcher.RunAsync(Windows.UI.Core.CoreDispatcherPriority.Normal, () => Generation++));

The TPL does not work with UWA very well.

Somehow the task is stopping it's work, but UWA is not telling me.

Hosch250

There is a difference between not working and being marked as finished, I think.

Q: Three numbers calculator

I made this three-function calculator. I have been learning C for a couple of months, and I learned C++ through the internet. This is my first "real" program in C++, it started really messy but I did a lot of refining and debuging and deleting unnecessary code and this is the final result. If you...

Q: Get parameters of many 3D objects

I'm working again on the 3D model of a building in order to parse in JSON every parameters of every objects of the model. My program works well but it is too slow because of the huge number of information : about ~10k objects each containing ~20 parameters. In order to get a lighter JSON we organ...

    query += ','.join(columns)
TypeError: sequence item 0: expected string, tuple found

The joys of dynamic typing.

It's an array of tuples and I'm doing it stupidly wrong.

@Mast wild guess: flatten = itertools.chain.from_iterable; query += ','.join(flatten(columns)) ?

or just ','.join(itertools.chain(*list_of_tuples)) maybe ? ^_^

Mast

Since I can control what columns looks like and I probably figured out how to avoid requiring tuples in the first place, I've simply made it an array instead.

@MathiasEttinger I think that doing the way I said will avoid lazy evaluation right ? :D

@Dex'ter I think both are equivalent. But looking at the source code of chain.from_iterable would give you a better answer ;)

    # Here Be Dragons
    query = '''CREATE TABLE IF NOT EXISTS {} ('''
    query += ','.join(columns)
    query += ')'

    cur = conn.cursor()
    cur.execute(query.format(table_name))

And yes, I should wrap my cursor, but that leads to unexpected behaviour for some reason.

So I'll have to fix that immediately after it works.

Dragons are pretty epic

I think I'll read this article waitbutwhy.com/2013/10/why-procrastinators-procrastinate.html about procrastinating later today
