From YouTube: .NET Design Review: IBufferWriter

Description

We'd like to review the proposal for IBufferWriter:

https://github.com/dotnet/corefx/issues/34894

A

All right so awesome: do you want to give us an overview of what? How.

B

You want to run this sure so busy what I wanna go through the motivation of why we want to buy a documentation of a book writer and now the moonlight scenarios is really providing gamefication writer, which accepts this interface, which is a new interface that we ship into one called I, prefer either, as mainly meant for synchronous writing to adapt to buffer that the user basically provides provides us. We don't ever just mutation writer, support writing that into an array or write industry.

B

That is the primary thing we I want to turn resolve and silly favorite writer is a desktop, there's difficulty in terms of when do we dispose the memory, unlike memory and and we also cache the span as field, which is why I said after so we can't really accept its player stream. Then I redirect Lee had grow the buffer under-run lying over ourselves. So the plan was is to provide the intervention of our provider inbox. They pull that, and the user manage the disposal of this type. So then, you'll describe a positive integer rider.

B

The only two other type we have today in the shader, the fresh air frame but talked about this interface is pipe rider. So people who are primary today making is except thickeners, pass it directly to the deviation I. Don't what else? Okay and 500 has a method called flash I saying it lets you. Do this a synchronous write to the actual output? Whenever you are done, writing some data, that's the main motivation and probably I will fall.

B

Another thing is we: we shift our interface, we don't even single implementation, and we generally try to avoid doing that. So, as part of that, we want to make sure that you need, while some page in box, for the users they can use, or at least leverage SAP application when they are trying to cover their own and it also certifies the contract bit more and I keep quite if you feel better around the neck of companies on this interface.

B

This will help drive data go at least a discussion and we can all go the same page so yeah the UK surface. Is there aside from this limiting I disposable and because it's dead yeah, it's like advance to get memory gets bad. The key thing here is that I did too much this coffee method, its except the stream. The copy do and coffee a sec copy to and poppy to.

B

I said this is the bad program model, which is somebody in stash here, Saturday night, the but writer, the partial, which is a writer once they're done secretly writing to the Jason writer. You have a copy to it or what do I say onto the stream that you want to inspect it after after they write the.

C

Whole buffer right.

B

Or then to track, if they're written, let's say they're writing, but to give multiply, the mahkumat should be about a beta crack. Some threshold periodically got copied. Is it why.

C

Would we not do it kind of automatically basically create a wrapper for a stream that implements ibuffer writer.

B

Mainly because of the semantics are advanced, which is you don't flash now advanced correct, so yeah I prefer interfaces only had advanced get my understand. It have a kind of flush that what why do you write to the October I was three or.

C

Four, when you've come flash on the on the Robert, you would have to manually call it. This problem doesn't go away, no matter what the API is. It's just here. I can't have to do that as well. Yeah. In addition, I have to worry about calling copy tool and I would want copy to p2p.

B

To edge of life, oh really, yeah! You can't come because your big writing to underline reboot that buffer! So sorry that your anything already that keep going, what you're done, writing.

C

B

I call cookie to twice.

C

It doesn't copy the data twice um to this. Okay.

D

It basically it's.

C

Not really copy tools, it's.

D

C

Delete what I already heard I think it's not very intuitive, then.

B

C

Crave a wrapper full stream, as I said, but.

B

Now I don't know, stop already.

E

Copy to a sink doesn't call flush for you right. It just calls copy to a sink on the screen. You stop to call flush manual yourself,.

B

E

Calling copy to a sink and passing a stream, we don't this class under the hood, won't call flush for you on corresponding a stream correct.

B

That writes to the stream I, don't know what you mean, though,.

E

You're talking about flashy, um we don't watch the stream for you. We will copy to a sink on the stream for you when you call this method night, but we won't call scream flush or flush a sink for you. Yes,.

B

If you just do like a sink or rack to the stream, you think.

A

The flashy, referring to the flush on the buffer right all right.

B

There is no professional airport, then.

A

One flash that uses the word because you mentioned it reflect for you, though, in.

E

A stream, so so these two methods here copy to and copy to a sink, take a stream right and we call the corresponding copy to or copied to a sink on the stream. But we don't call flush for you on that stream. Yeah.

C

What would you write, yeah but I think so that is a good kind of additional point, but I think the biggest issue is. Nobody will know that this copy tool can be called periodically and that it clears there already was written. It's so nothing not how copy two methods work in the framework right I also.

F

Why can't this rap stream or the array case, because memory stream takes an array, a byte array that it writes directly to right? So, if you're, so, you could write to a fighter a backhand binary using memory stream. If we had this just in Poland well,.

C

But it doesn't stream, but it's not this, then it's not as performant I mean the performance kit would be quite significant, now you're making more hops. So how is it related to this feature that the Jeremy was working on? He was working on this hills, riobamba Rider yeah, exactly I was getting at the buffer right there. It even says array buffer writer, so.

B

It is hyper brighter, so I did the top Radison yeah.

C

And the rights to an error, in which case was also doing there, but.

B

um After I get here, then he's not. He doesn't like to dream like this copy.

C

Api well and I'm arguing this API is not very intuitive for writing to a stream I think we should have two types: we should have the buffer writer that Jeremy was working on and I, don't know the whole design discussions that popped in through some difficulties in issues and we never made progress, and then you should have a separate type, which is basically just a wrapper for stream that implements ibuffer right. So.

B

Over rider is not plan for your UI is put out, and this is a scenario need to resolve, or you give it this value, so I need to write to a stream and I try to run away. That's the primary motivation here right if buff rider was able to do that, we will be doing it if, as far as I, actually what the design work does not allow just to write. I can just rewrite that utility, which is my linear.

B

Okay, like this and then the second reason is, you want to implement an interface of this type of an operator and we don't have certain interface. So this acts also as a general purpose idea for anyone who wants I'm sorry for daily progress, so what I did, but what you're suggesting is not the same thing. Why.

A

Not because what you're suggesting is you have a stream that implements ibuffer Rider, it's different from being able to take a buffer while and writing it to a stream. So then, you have the string of implements ibuffer wider, but it doesn't give you the ability to take an API either takes I buffer writer and write it directly to a file stream that somebody gave. You know.

C

You take the first stream that they gave you. You wrap it in this type that I just talked about, and then you pass it to digest right. It was enough. Okay,.

A

By wrapping you don't mean the type of you don't mean it right. That extends fuel implements ibuffer writer that you're asking for sometimes they're basically come together either.

C

Type that puts them together or what you just said could be done too, because this is an interface, so it could be basically a you know, a buffer writer stream. It would be called it takes stream. It is a stream and it implements this interface, so you can use it either to write through stream in turn, but that stream interface but I mean the abstraction probably doesn't make a lot of sense cause it's just.

C

If you call the stream IP is you would be just right, calling a wrapper for no reason yeah, it would probably be just the type that you know implements. This interface takes the stream and I think.

A

It won't just the class that is provider or stream buffer wanna write that implements ibuffer writer. It takes a spin, but that is not itself all.

C

We could, you know, implement type of writing on stream now that we have default implementations of interfaces anyway, not that one is probably too risky to complicate it, but so also, if you ever asked for anything ever yeah.

A

C

So what we're like? Why did the battery turn this car since the Germany feature kind of stopped like what like? Because there were some like I talked to him and there were some shooting things to decide, but they were like well, we just have to make a decision and move on it.

B

Was mainly on timing and scheduling I just well, why can't you take a look this type on time, but not the other.

C

B

Lot more lighter yeah, while this latter.

C

What what is the, what what what does the other one to and this one does it the.

B

Other one is a whole feature-rich thing which has much the api's meaning remedy is supporting all either primary types like a lot of it. Really sequences is enough reserve. The bytes are witnesses, bye-bye all right drip the byte thing yeah. So so that's I think that we found out or not I like you should do it. Okay, this this is more around I, want an array: are they bad, I'm, afraid, intimidation? The carpet will just help us to they add it onto here if to support seriously it lesson you come together. Is this?

B

The user would just write this. We will give them the array gave ready to and they will handle the copy.

B

So we gotta move the copy to api's and but then I just heard usability for the screen case today. So so we can make it add stream rapper in the stream, but.

C

The the stream rapper yeah we need this time. Why would we not.

B

C

B

I came over for one feature, you say.

C

We need more features.

B

Of the stream prefer I drove over yourself. This is just one thing: okay, okay, okay, but this won't go through this.

A

One requires you to buffer effectively before you actually write to the stream right. So if you have the other kind of their basic directly rights to the stream, why would you ever use it.

B

The nation rally does not accept a stream based. It would never like that. You must evolve buffer. Actually, since, if you're doing a sing song it will buffer groups or some online array like asynchronously, how must you heat some sexually? Then you must be already all right to the stream, so the only five-time can avoid copies. Please read something.

F

My way, but isn't that just a limitation in the Jason writer and you don't need a public API to create the bridge between having a buffer and having a stream you you just internally need to say: if the user gives me a stream, then they can. Then they can right click. They don't necessarily need this River Bridge, you know, but it's stream fundamental. He requires buffering and copy well. I do.

C

Actually, unless.

F

It's a memory stream and there is no buffer, it just writes it's.

C

A it's an IP I issue, so a stream that right takes a byte array or is no other way to write anything thanks about yes. Well, the data needs to be in the battle to be able to write to a stream.

C

It is a butter. The name butter means somebody is. There is some data that is being buffered. Somebody has to first write it to a buffer, so you can then write into history.

F

Right, but that that can be a local buffer can be anything else. If you have this as well, then you have a third buffer, no.

C

That wouldn't be there wouldn't be if we implement it. Basically, this wrapper for a stream. It will implement a buffer writer and it would be exactly equivalent to. There is some buffer bytearray users rights to the buffer, and then the battery of the key gets basically written to stream. It would be.

B

This type and stream wrapper have.

B

That is it the buffer, well,.

F

Right but if you're wrapping a stream, then the stream is the buffer. No you, you have the bunker. So so right now you've got the Jason buffer and then, if you have this, you have another buffer and then you have the stream. You.

B

Have a barcode: it's grabbing the ruffle from yours out for sake. Oh, it's! Nothing I prefer edit. If we had to get standard memory, it's required, it gives you the buffer. So in the vibrator case, I write on his buffers, it returns to you, the buffer, that you are active, so you write directly to the output stream case or in this case, given a locator for my iPod, give that you that's a bunch of it and then we just write into it. We can give data stream if.

A

You think about the interaction and I. Just looked at I borrow it again. The interface looks like I.

B

A

Right I base it. Just gives you a span, you say: get span for I, think about four sides: right, yes and then effectively. So in that sense, I buffer writer provides you access to the underlying buffer you're supposed to write, and that just exposes that as its back. But let's say you create this time because I was proposing like the stream buffer Rider right, which base it takes the stream taker and implements ibuffer writer.

A

That type effectively in its implementation has to have an array that grows because the thing is, if you call get span URI, which is your interface to the people that take a buffer, whether you have to give it something to write to write when this guy is done, then, basically, what you do is you call stream dot, write a sing or whatever passing in that buffer it so like your implementation has ever buffer somewhere right.

A

So what he's proposing space is saying that I'm having to just have one which is this guy and then just have a convenience method that gives you the ability to just say. Oh, you know in order to write to it streaming and supposed to you doing it, you just copied.

C

By the way, I have an idea how to solve your problem of schedule and in one feature or another, just why do.

E

C

A sink to this type and make it virtual and basically.

C

You ship this type if I want to write to a stream I inherit from it and inside fly TransLink, I write the buffer into the history.

B

If this guy becomes virtual, then calls to gets patched up doors for downloaded there's.

C

Only one methyl bill, I see it's flash, I think and basically so, but I inherits from the side, because you cannot maybe in the future we ship the inherited types back, but for now I inherit from this time. I I add the field stream that override flash I think in front inside flash license or grab this memory and write it to the stream. There's.

B

Mass spectrum, what do you think a tutor today is if ever I prefer either but the other spectrum? Is they have this type and they do not do any of them discharge box you're staying here they have to write the flash I said you simply misread provider. Inbox liberation of I said it's about method, meaning it's not base. Go me. Implementation already, defaulted, notation, 3, provide interpretation already.

C

After maybe it's not a good idea so.

B

C

Depends who would call the flash is saying right so I don't send.

A

The flash a sinking, so why do we need the API at all which the flash I said yeah? Why don't you just inherit from Maria before right, I call you today well.

C

I've seen it should be smooth pass, but.

A

Let's say we don't see them, but, let's say inclusive Katie. Listen here! It's an array buffer rider called stream buffer rider like why do you need a virtual flush asing of the base? What would what does it by you.

C

Maybe it's you maybe right because I was I was imagining that it would be integrated with the JSON right there. So I don't have to worry about the flash, I think, but I have to call it anyway. I mean.

A

If you really care I mean what I would suggest, instead of doing that, I would sustain from an identifier a sin disposable and make a hissing disposable call flush. I, see.

C

No because then you want to flash periodically, you don't want to flash only when you in this box sure, but.

A

That, but that can be handled by by whoever handles it. Right like it's like when you change the contact of the Rebbe, a provider to say the consumer has to copy or Italy flash icing, because for the array, kids web.

C

Bye-Bye would you ever do that so I'm, not sure I'm, just saying that, like I I, think this possible doesn't solve the problem. So these.

E

Are just two convenience methods right you copy copy async we didn't have them and they'll be like one or two lines of code to your.

B

Sample that might hurt.

B

So the first one is not straightforward: cigarettes like to fight you see where the usages at the last line out to the copy to pass through, so the fashion got use anyway else inside this room writing the code, where you write into just an idea right, so it.

C

Could just be the user yeah, they would have to manually just basically say first thing that right, you know outputs or whatever the current buffer, yeah and then clean it and then move on okay, I would just remove those copy stream helpers, one. So one addition kind of architectural question, so this thing uses the buffer pool to allocate buffers. How do I return the things to the buffer tube is disposable.

B

So much you get rid of the rainbow project so.

C

I basically have to hold to the instance of the.

B

B

Copy attachment get it done hmm or on wherever you resized underlying forget it run this. So this is about based on the British products. We hadn't offered that yeah.

C

This so this is I'm not sure if it's the best design, okay, because why is it we, let's say I, you know, wrote an array now I want to send it over the network.

C

I kind of need to hold to this buffer writer till the network call returns. Otherwise, I cannot dispose the buffer before I know that the thing that was sent that's a bit of an issue not.

F

How most arrays and streams and everything else work, even if you were to do it manually now.

C

If I did it manually, I would just go to the instance of the array and then return it to the pool when it comes back now. I have to go to the instance of both the array and their item, because the only way to return the right to the pool is to have the rider right.

F

But that's not going to be expensive to do I, don't.

C

Know I mean it's not that it's expensive it's now I have to potentially have two different fields. You might think that you know, does the network interaction, but would you hold on to the array at all yeah.

F

Because the buffer is holding on to it, and so as long as you have the rider you have, the array and I didn't think we exposed the array anyways. We just exposed span and memory. So.

F

Hold on the array, your sofa back there.

B

So, by the way.

B

Some people know it was your voice.

B

Easier than line up data, how do we know that users it periodically flushed? So if you start writing on the be near death, that's what all the primary reasons to have to copy to method rather die on the user to like to the stream themselves that we maintain state and already evaporated to know beer we incorrect. So if you remove that, then the user has to do more more letters right to the stream, but they have to reset the Remo prior to them. So.

C

On a bit of a related note but separate question, so our JSON writer does not support writing two charts implementing this interface without boxing them correct. We remove this feature. Yes,.

B

If you were to use, if you have a strength-based limitation, then SP box said you do not see that the caller will not say. Okay, we copy wire.

B

hmm If you look at the resync sample, this is what I had in my room, which is you keep write it as you're writing an array of elements right suggestion and you track how much you've written once you pass them sink right. Threshold I'd say about a million bikes. Then you do the copy to a sink and then continue, but you're right. That's how you support! Writing, diverges and large files.

B

Just try today.

B

So I'm not too sure how great will be video people to come to the Maddox.

C

Yeah I, so this is actually not before I. Do don't have access to it? It's all. You know related to portability.

C

We don't have in the in net standard, API stew, right memory to stream. This.

B

Is why I discovered Dominic's.

F

Well for memory you just have to do memory get span and then write the span history, so you do have that either. Oh you mean.

B

In standard yeah yeah, so other reason why we may want to have the copper 2 minute we're.

F

Not exposing the span overloads into one a necessary one: yes, but not good right, but then, if the jason writer going to be in oh I thought that was also going to be 2. 1 I just write it available in.

B

English, nickel to you and a source that is that if I try to it Oh as.

F

A source package for Oh.

B

So this polymer occurred today occurs coming today in things like core setup or anywhere else, where you write to stream and then you to use the distal writer so as part of a at least a stopped-up feature to make sure that that works, and you can remove absolute upstream dependencies, easily PDA type ideas, we definitely a type. You are a provider which is my psycho provider. Now we got any coffee to or not that's arguable, but either fix evaluate. Why.

C

Don't we just give people access to the array that you hope to see? You are afraid that they will mess up the pruning and.

B

Again, it's like how many can be my neighbor Friday themselves today, I passed. That was never never the concern. The concern was making sure we have. Some abs are in two edition in boss. The users don't have to go either way. Every user does have 12 variety, so the whole part is this idea to is to make it is coming it and to private, based on the scenario that I need to write was trained, so the copy to method in a inherently supports that so that the user has to know no work.

B

The internet is typing words. Also.

A

Don't know Vidya this I memorized a minute was considered a mistake while giving the unlined all right. Yes, we basically change the behavior so that if you didn't pass it in the array, you don't get it or whatever, because otherwise you you up there, because as soon as the guy girls you're screwed right, because then you're holding on to the wrong way like it basically breaks encapsulation in general. When you do that, and then you have very subtle bugs that are hard to pinpoint so.

C

One thing we could do is just basically change the behavior of the copy to methods and say you cannot, you know they don't clear. I think this is basically the unintuitive part well, but no matter what right somebody has to remember to periodically do that. No.

B

You do it at the end because you cannot, like you need to clear the online buffer. It's very much buggy Rivera yeah yeah.

C

This type is not full writing. Multiple things of data, how.

B

C

You implement a stream I.

A

Think so, I'm thinking about it I think what we probably need is like the time to crystal suggests and the vein of this try. The ads is yes, it did so you could imagine that this type is implemented by just having the array buffer writer as a field, and then it just delegate the I buffer writer to the underlying thing and then also periodically cause flow. So for you.

B

I have four times a stream.

A

Buffer either yeah because yeah, because the stream I'm ready to read the value that it really adds. My opinion is to periodically setting the data and on the wire right and knowing when that, when that's a good good.

B

C

Buffer I would have to copy do method. Well, there is so.

B

C

There is a fundamental problem: you don't.

B

C

Over the wire, why? Because my partner writer is a synchronous interface right, send buffer over the wire. You need. The nascent called JSON writer does not have a single a synchro yeah. So this.

B

Time, that's why the started racing them and assume I, don't have the same thing. Yeah.

C

And then you know, Jason writer would not automatically call this AC method periodic before yeah yeah. That's.

G

What he knows saying.

C

That you know that periodically the stream writer would call something for you, I and it's kind of true. If somebody directly uses this wrapper type, but if just passes the ibuffer writer to taste on the writer, it won't happen right. Whatever.

A

You say no matter what there's a new API that is asynchronous, that one person has to call and we can decide whether that, where that lives effectively right, I.

C

Mean it seems like you know, it would be useful to have rena. I a sync battle. Writer and json writer takes it and then jason writer has a flash method plus a sink and.

B

You very much I think men have because you're after what? How can you have a pleasure? It's a mathematical answer. What's up sorry, yes, trap Oh.

H

A significant restaurants way: that's.

B

The primary reason why, even if you were to extend database well, the option is that we Polly Zuckerberg.

E

B

Away its provided, extend the iPad interface treated as an eye facing buffer edit, which has the fresh icing method. Its Piper I didn't even consider intimate. It comes in handy per fiber only in device, but they have fresh is imagined by Bible.

A

Never dated how does this work today so today you would say, let's say: I have to write. I, don't know five gigabytes of Jason. Oh my bad service right. So the idea would be that the message that does it somehow is.

I

A

Has to batch and then unwind the stack effectively keeping one to the Jason readers. The date invited stayed through the flush, acing and then again, new amplifier adjacent. My tyrannical said.

B

You know get a sample below the other like to write, be about support yeah. That is better, and the thing that's writing is that so you can't escape you restructured a nutritional writer. You write some jalapeno, let me say a million bikes and then our method of writing, because of it.

A

It is, unfortunately, the colorist.

B

That's what we have today, it's similar to the per ml for leader and right and the same thing and I see value in the cooperative methods, especially for this is to another scenario and what we have today, how do they actually do? But, besides just the only obvious which is right.

A

Taking it away in there and lengthening.

B

What would they have to mimic our commitments? Yeah if we don't have to tear down the language? Are you afraid, mother to me said they sent the cursor back to zero? Here's some data, especially.

C

Because it's not only copy, it's basically copy and consume its kind of copy. Exactly it's like to look.

B

At a permutation, actually I have a link to it that helps yeah I was at the store today. That's are you going.

A

This is co-op earrings for them.

B

Yes, well, oh yeah diversion you can see. Is that your puppy? Do it.

B

As it'll shucker.

G

C

Help her and clear helpers I think so additionally, so.

B

Is the data you've written.

C

And research, the cursor method, so I think we have scenarios I still feel this idea is not what we ultimately want to give you another example of scenario that I think I imagine people would want is never resize the buffer when you're about to resize. You know.

B

Call me so I can copy to and move on so I'm fred ages and you can be made a fixed size type of rider very strange to me for custom scenarios. We have the image I prefer it I mean you haven't. If a cyber predator there's nothing stopping that scenario, the question is: do we provide something? That's easy for you to do. Look on board! Yes, right! How.

C

Is the provided by this time this time sorry.

B

It's tribute is tribute to implement and on growing big size, buffer I did the radiation that's backed by a fixed size rate so and I don't know how come a nice area. So that's the reason why I'm focusing on providing this study, which is so that anyone who doesn't know anything it's what's right data we are able to do so. You in the right, but.

A

Then you're still back to square one because like when you it's the same problem that you're all done before, when, if you say he never grow at the time, you grow your in the synchronous context. So how do you do anything in synchronous like Mary made it to the wire.

A

The thing if you want to have a scepter last thing, you need to lie on somebody in an asynchronous contest. Pinging, your perfect way to say: do it. Will somebody answer back to the order loop, the net synchronous.

B

Also, the fixed size are what happens if you're there that was unexpected. You throw people work before the fix, I.

C

B

And you start writing more than was required. So he's.

A

Saying there's a callback in the copic has to do whatever it takes to make yeah well.

F

If you're doing with the stream, then the stream takes care of the buffering and the flushing as needed when you fill the buffer, but in this case it.

B

Is a fixed size buffer? That's just for K! You may not be done. Writing your single doping. Yeah he's on m1. Why do you flush, yeah I'll, touch periodically value in the middle of writing? Yeah.

C

The buffer, never you never can continue it parts are talking runs. You can only continue like. Basically, he could really call and say: hey, I, don't have enough space to write the next token. You cannot ever basically call you and say I know pallet of the talk, and can you give me a larger buffer, so I can write the other part well.

F

I mean if this, if this interface or this strong, took a fixed size buffer and had a flush method, then when the buffer was filled, you would call flush and continue writing whatever rest out of the buffer, that the user gave you to copy from until that was done, and then you would throw who would go to the flush whether you would have to when the fixed size buffer was full, because the user gives you a buffer that you're copying from and it's the same way stream works. It's it's you're, not you!

F

You have all the data you just have to send it in small packets to get it all processed.

C

um Well, he doesn't have all the data this sometimes degrees basically have all the data means. There is some buffer that has the data. Well, he's actually writing to their buffer, and if the batter is too small, he cannot have all.

F

The data, what happens if you have a token that is too large to fit in any dotnet allocatable buffer, then.

B

F

Conservative or yeah.

B

If you are anymore that took a bite of JSON string single string, that's gonna! Do it boys, yes,.

F

But that seems like something that realistically should work, and normally you do that by buffering and then writing small packets of the buffer right for to support that.

B

Scenario: the user. We have to add your custom, because that is I have not related to that issue, or that ask where someone is good. Looking to write more than one gig or single day.

F

You could imagine it's not necessarily always a case if the user has a large token. It could also be a case of the user. The users app in general has high memory, overhead and they're wanting to write, maybe like 10k of data, but but for whatever reason their app says. I can't allocate that much data. Another Sol because well.

C

But I think what he's saying is what you said. The scenario is valid and it can be implemented, but it's a more complicated feature he's saying: can we have something simple for the scenarios that are very common today and I? Think it's close I still worry about. The two is saying basically doing more than what copy two extinct methods in the framework I think it's very unintuitive.

C

On the other hand, if we remove them, then because this type doesn't give me access to the inner area, I cannot actually use it in the portable library and by the way, I object him more to the.

A

Name like let's say, we've renamed the method to make it clear that it actually does clear up, because that address the problem. Yeah, possibly I mean like move to a Singh or something that it seems.

C

Another thing we could do is, basically you keep them as copy to a sink, and the user has to manually. After calling this method to clear the problem.

B

Is they don't have the quality method? We have to do that just resets the index, so yeah actually yeah. So.

C

Actually, if this copy to async always copied the whole buffer, you would copy to a sink and then clear.

B

So yeah you could sew the cockpit like the user, asked first copy, then clear and yeah.

A

It seems like that's almost a menu at that point you may want to provide. It was just the one method where, because you mean why would you ever do copying not clear? Well.

C

I think it just make it makes transparent, what's happening sure. But now you have like, because.

A

Of this is like you can look at code that looks reasonable, but do you know Lee Graham or like crazy cuz? You forgot the clear method. Well,.

C

Then you called wouldn't work. You have a bad, it really wouldn't works properly. So I don't even.

E

C

The data every single time you care enough, so we could I mean if we have a great name for the method, you know sure it would but I don't it's called move to. But that's that's not what it does it moves. The data memory takes.

A

The memory from.

C

A

C

Maybe still can I, how do I know how much data is written, no to the button.

B

B

No I can expose it, so they don't know, we don't know how much you learn is.

C

There a way to because, basically for the you know the scenario of I don't want to every size or I wanted to minimize resizing. If I could basically check some properties like how much free space there's delays so.

B

So we had oh yeah, do you have by sitting and by some idiot I, keep forgetting and we can make this up as well yeah by so device committed, and we have the output as men. We have put a spell, so you you get the slice of data that you've written, that you actually forgot this data and you also have a majority.

A

A thing: if you want to implement a policy you want to know how many bites you have right, so you can make smart decisions about counting the bites. If you.

B

Go back to the yes service. I, just wanna make sure that you're on the same page, but.

G

Literally, we are I.

E

Mean you might use this is what I did I subtracted the two and I'm like okay 90% of allocation? You know time to call copy to or manually do it like getting the bytes or the span or whatever I see.

D

Because, usually the ratio between me.

C

But the full size of the buffer is it not the full size because I want to know I just need to know how much free space there is. That's what I need to know. I don't need to know the other things. I just need to know. Free space like cuz I'm, about to write an int and I know.

E

Referring to I thought you could subtract the two it you can't to get the free.

B

E

Like like, okay, you have an example usage down below and you have this threshold right, yeah, but I mean the threshold could be like hey if I have. You know, if there's only ten percent of my buffer left, I'm gonna stop right into it. How.

C

F

Well, isn't that just bites committed fights, written.

F

B

Bites committed should be no I need to know the full size of the buffer he's asking for the size, darling.

F

Right because you could have committed less fight, spin, the buffer, yeah.

E

Yeah so I thought that meant something else actually is so on. So.

G

What is another.

E

One called bytes allocated or something.

B

D

E

B

What is my it's Canadian music? Have we done caught me a seems to do memory hums, you good, so.

A

How much so it's the total number of bytes versus bytes written it's just basically in the current yeah, which.

B

Is why, when is it all wasn't in I, see.

A

B

Imagine can never grow more day so.

C

I think it may be exposing a property called capacity. Basically capacity is the size of the buffer, and then I can just subtract from capacity by well.

F

I think by threatened should probably called length or count like everything else. If we have capacity yeah.

A

Capacity should be the size of the buffer length is what you having.

D

A

Buffer, that's the wall. Speaker.

D

That's the local count, not the total list.

A

Thanks I think this is the size of the things you have in the buffer and the capacity is the size that the buffer is I.

B

A

B

Right now, the reason why I want to keep the budget is the parity between vice come in a bunch of it. No.

A

I think that makes sense. It's just that late I think length should be the current buffer window or basically, how many, how many have you have and then maybe you have total bytes written, which is basically well they're. Just basically like everything you ever have done right, I thought.

B

That which seems.

A

B

I find it rather than being in school and being in trade. Oh yeah,.

A

I mean at the end she said random. One can never be more than two gigs and yeah for almost everything you would do with that number. You probably wanted in the end of the day anyway, but as you pass it to expand or whatever right, but.

C

I wonder whether the binds or bites committed you have even a question doing interest. When would they use it.

B

If you I do namagiri into the stream, otherwise the user would Pat it in themselves, especially they want to move something I.

C

See yes, it's actually important if I want to right too extreme and know how much exactly.

B

A lot of my motivation is to our body quality code that you have to write yeah.

E

B

Provide features like animal encounter and remember yeah.

C

B

Lot of this racket before you I'm.

A

Trying to popular belief, we actually do think you being imagination. So there's one question so one was Ivan is asking: why don't you expose read only sequence of bite from the array buffer writer that way I can copy it to wherever I want. That is not a stream for.

B

A

You're not really a sequencer you're, always a single single.

B

Contiguous memory yeah right, if you have but.

C

Do we have a conversion from memory to read-only sequence,.

A

I think the read-only sequence of white would basically be an ibuffer write up a letter spec by an eye pipeline. Oh right, yeah but um I, don't know.

B

Committee well.

A

Like, logically, you are a connected buffer and you're I. Guess in this case you wouldn't buffer already, would just write it out as soon as you can I think that I think the the logical problem is that we don't want to keep everything in memory. Whether they were, the only sequence would would indicate.

B

One so far, one thing that was it's also considered I know, aside from streamwriter and buffer idea, which I feature, then you want to add is sequence based private, which is instead of allocating a reasonable time. Tv.

G

B

Append to in memory- and you keep throwing it using memory, pool I tried that approach and I mean consider adding another imitation of that debate, which is may may be memory buffer. I wrote a like that, but it made things that gets pan and his lower because you have to always productive to memory.

B

Well, you avoided the constant resizing and going the unlined because you keep opening size. No, professor, so digital of to be made here separately.

C

To examine one thing about the api specifics: why would the I buffer writer API is not be implemented explicitly? What.

B

Is the benefit is that they.

C

Are hidden because they kind of I, don't know you know like consumer of this type. Probably should not call these methods directly, okay, because they are kind of tricky to call like what do I pass, there's a hint and whatnot, and yes,.

B

C

Proposal I'm not sure about that, but, like one thing I wanted to run through, is then the three methods that are the I buffer I current implementations. Should they be implemented explicitly? Oh, how.

B

Are they hidden money? You just implement they're explicitly nearby.

A

B

Are they hidden, okay,.

A

You have to can step up right here, I think the that's probably fair, because you would never expect somebody to new up on the right before writer and call ibuffer writer methods ever right. I mean maybe.

C

You could you could, but.

B

Then you know they just need to cast our buffer right right word if you're doing something- and this is your interface bit to right to an area pool no custom data- is flash machine. That's naughty! To be gesture. Writing something else. Do you think you want to use this ApS, so this is the value in your edges. Do have a scenario. Is there a breaking change to go from an explicit card interface interpretation to explicit.

C

I, don't know but I don't think so, but every everything is breaking change right. We just need to look up in the document whether this one is really.

B

Something that we care about so I I mean I. Think of this as where users are using this type of as standalone type. It's nothing related to underline, rather than accept I prefer red, and then there were new details right, like I just want to write some hints Christine.

B

I won't be, then I would do that boss and get this bad stuff that just back to the data.

C

What, if I already have an array and I want to write to it, question.

B

Your contractor here in sequence, are not really actually that's true. um You could provide an overload. It.

C

Complicates the situation a bit because what happens? If then, you need to resign right, but.

C

It may be a real scenario.

B

So again for speech size before it is nothing stopping you to pediatrician library, be positive, so I want to avoid the corner cases and focus on the main items that we actually have. I agree that this many things that are not supported today so for I did know a fixed size buffer. Like yes, you haven't already, and you need to pass through this writer and you don't get what it going.

C

So if this is so okay so and one last thing, yeah, maybe because I need to run soon yeah, could we just implement a buck? A writer and list of the on list of team.

B

hmm Because it matches that going for you already.

C

Because, basically, it's winter, mr. three and after right there methods explicitly yeah. The rest of the API is are pretty much. You know what list of II have and nobody would even like, but I don't know. Maybe it's taking it too far anyway. I need to run alright.

F

I also think on a list of T the gets ban method that takes a size hint that doesn't return the underlying span, but resizes it that but returns the remaining capacity and potentially resizes the underlying capacity to match. That is really confusing for something like list of T.

F

Docks and I think that was api's in particular are confusing in general, but my.

B

List of T with me even more so because she did then it.

F

B

Gets all the specific questions I had how he, finally, the name the type name as being able forever.

F

Given that it only rights to an underlying array, I think that's probably.

B

Fine, do we need to say the name fool in there or doing to say binary, because it's everybody I prefer by you in the buffer is generic.

E

Yeah, it seems like I mean it's it I'll bite, it's you know so well, ray by itself doesn't seem right to me, but I.

F

Don't think binary makes sense as well, because mostly other places where we use binary it supports writing all the primitive types of data rather than just bite. Okay,.

B

What do you have any nice additional money? Are you good, didn't II, which part are you able friend, as a bad name, I? Think.

A

I went buffer, writer is fine, I think did nah.

F

I, don't like memory buffer writer, because that would to me that would imply. It also supports pan and on memory here, buddy backing data I.

A

Mean you were baking and buying array or ID in the same way that if they were to do the type crystals addressee would call it stream buffer rider, which is basically a Beckingham by street, like that seems the fact that it's also holding on to neighbor an array buffer writer. It's just this crystal said the way it spins work in general that somebody has to buffer right. So that seems you know not fine, but that's just you know, I think the.

B

Way the Chromebooks do we need to support customer able to the user passes in rather than using the shares.

B

F

Have a very cool interface, though right now public one I didn't think you could have.

B

F

Your custom variable.

B

E

Oh, it's you'd have to create another interface or something but I read. We.

F

React system buffers are a pool, no.

B

It'll just be a basic attractor, although in this case which accepts the pool right now, we used a shared pool. If you take it as a custom pool that they wanted us to use. Is this an episode or it's something to get before they don't there's a task today is only for today, I just I didn't want to just hold out there. Yeah.

F

I would think allowing a customer a pool would make sense, especially for for performance oriented scenarios where that may be. Okay.

B

So I don't know if you try to be up to me, I would rather be, but the other key there's nothing. Stopping us from Maddie.

F

And the only downside to not exposing it is that anyone who wanted that scenario would have to wait till that standard 2x and before they could use it. So what I.

B

Don't know if you were able make you do recording data by shooting it's not going. Yeah bicycling is totally legit. So.

A

That's just the conversation I have Nick Craver yeah, so basically, what I recorded was. We should rename by it's committed to total bytes written, invites written to length and we should add capacity. The problem is that Nick is pointing out. Is that length is somewhat confusing, because if you look at the other types that we have its list of T or string builder, they don't really represent sliding windows right thanks. So length is always everything you have written right. Capacity is just so big in the buffer.

A

Be right in that sense, I think capacity is fine. There's just is falling off. You know ii love. I it's written versus length. Maybe we should just have total bytes written and bytes written. Maybe that's good enough and, let me just say bites witness within the current. You know incarnation until you call flush, yeah and then total bytes.

B

Readiness effectively, if you do that, then I I don't know why I couldn't have been committed three days so by coming in. For my.

A

Whole, my stronger argument is: did from all the four people in the room, many Tooting Steve on the call. Nobody knew what it meant. Yeah.

F

A

Capacities, I think the the the easiest way to think about science.

E

A

Invites commit addresses by it's written I. Think it's unclear like unless you look at the return type, there's no clear, but the relationship is right in.

F

This particular case the most important information, including the information that would be useful for things like gets pan, seems like it would be bytes available, rather than the number of bytes that we've consumed out of the span that we have so far. So maybe we should consider exposing capacity bytes available, because from that you can infer the other but bytes available.

F

It's not only used internally in the birthplaces, but it would be used externally for things like can I fit it into what's remaining right there and then total bytes written indicating how many things we've actually pushed through the copy tips. So basically they move Missy gives.

B

You, the hint but they're, not get spend with you without going yeah.

A

Yeah group, whoever suggested bite spending the my phone with white spending, is that it kind of depends on your perspective so because, basically pending for what so pending to be flushed right. But it's not necessarily clear, depending on how you see that I think honestly, like bytes, written and total bytes written might be enough, because if you see both of them, you're like well there's only way you want to do that. Well,.

F

Yeah but then you, you, don't have a way of saying how much space do. I still have to write before I need to bro or flush. No.

A

That's capacity why it.

F

But then you have no way of determining how many total bytes you know.

B

You have to abide by his supervisor, fights.

A

Rendering capacity.

F

I think the bytes available what is more useful than the bytes written one I, think more I think most people will only need.

B

The binders at one.

F

For the scenario.

B

Because big question.

F

Is what you use for yeah I? Think most people will end up having bytes available because, rather than me anytime, they want to say: do I need to flush. They want to know how many bytes they have available. So they know, do I have enough space to do this or do I need to flush. Now.

E

Actually, you know what would be kind of cool is if somebody's asking for a memory, you can do an auto flush. If you don't have enough room.

A

But then you, this father was know every sink called. It has to do an asynchronous or a get right right.

B

And then you have to remember the street that your ID was rather than a button.

A

But I think honestly, I'm opposed to also exposing bytes available I mean yeah.

F

A

You can just document this literally just this one, this one and then you just write your code. Accordingly, right I mean I.

F

And I think that'd be fine if we expose both, but if we expose one I would be in favor of I it's available because I think that's what most people will end up needing. So here's the reason why used by ahead.

B

Budgeting is you keep writing until you read something so, let's say a million bytes, you don't come, you don't flush or you can come to me this way. So it's based on how much you've written that you'd then decide. Okay, nice reduce and retain enough data. I.

F

Think we're in performance oriented scenarios, people will would rather flush periodically and prevent resizing the underlying array, rather than just saying I'm, going to keep doing this. Okay, that's a big one!

F

Alright and like the underlying stream has a fixed size buffer as well, and it's not going to keep growing so in the default for that's like 81 K, and so someone might want to say I'm going to make this array buffer 81k as well, and when that fills I'm going to flush because I don't want to have you know a million bytes allocated on the GC. Okay.

A

Well, the only reason why you still want to have it is because you may not be able to do that. Okay, right.

F

You you might not be able to in all cases but I think.

A

Of your chick might happen after somebody roll data that is bigger than what your size was right. So, let's end you would just grow to the maximum. You need for it. Whatever your atomic, you know, units are right, basically ingest, it would probably be tokens or the J object that you're that you're fetching yeah but I think the yeah. I think that I think these properties would make sense.

A

The thing if you see them all together, like total bytes written by two written bytes available in people, will be able to reason about what they do over. These ones are a bit more in the yeah.

G

That's right and.

A

Then the other one we said we wanted to implement the ibuffer rider methods, as in its it's explicitly right.

B

Yeah I don't know if I about that, maybe because Chris respond is hiding and we call a basket.

E

B

Today, for if you have a writer that you write, but if you using the stylus download, you will call this a yes.

A

I said: well, how would you use it like? Why would you use this a standalone thing like what code would you write? Isn't it isn't it the passenger and you've used cases or the exclusive amount of these kids and you pass it through API?

A

That does the actual writing, because I know right, it's not great, but it's basically like well give me a span to write, to write and then have to do all the heavy lifting myself yeah versus that will probably wanna you up something else, a lot much of what the things actually want to write, either JSON or primitives or whatever write about.

B

The benefits of this could be that.

B

You could try telling bounce and while the net be fixed, will you write you advance by some amount, so you can fill it later with amount.

A

I hope communism not.

B

Very but I don't even know how I have to reason about how the gravity work and when I don't know the team exported so I've had it making an excuse me, but it wasn't asked to support the Pawlenty. That's right and I believe this would work for it. The little advance up front not as I go down in value.

I

Where did you determine initial capacity to 56 from.

B

Disappear overnight, a few fields, physics, so that Perez idea, there's no other, be a reason. I didn't want to allocate all right from the pool that one cave and what you wanna see a fork. A reporter unnecessary.

F

But if it's the array cool, aren't we probably going to have a number of 4k by version there already, because that's a common buffer limit used.

B

By like stream and other stuff, so the question is: do we have anybody quarter and then questions we have or DLP Buddhist or whatever else I think.

F

It could probably be in internal implementation detail what that limit is yeah like, instead of setting it to 256 here, yeah set it to negative one or something, and that way we can internally tweak it and people and.

E

Change it yeah.

F

I couldn't change it as needed, but we don't have to worry about Oh, someone compiled on against nets and ER to one right, and that was 256. We've moved forward and we've since determined that oh, it should be 49, that's six! Then they don't get that better. So everyone's fine, but keeping technicial lady.

B

For nothing, I, don't get what sighs I do, what everyone mmm and then that's what everyone.

A

Thought that Nick has, which is an interesting one, it's a! If do. We think the API servers of the type as not as a buffer, but as effectively the stage for the things you need to write yeah, then you would express your API calls, always not in terms of what I have not written yet, rather than how much space is left right. So you don't think of the buffer.

A

Is something you'll fill up to a certain point and then run so in that case, if you think of that, for maybe you should rename the api's like fights come attack by the things we just had I, don't know how we would call them, but basically I think if you think of it from a different point of view, you probably would write your API calls differently this by it's available. For example, it's not the question. You have advice available.

A

It's just you're, expressing your policy of Oddie to write the destination as a hint over on when he bites the available right, but that's long as the most natural way to think about this. It's more like home, you know! Is there stuff? Less that I should write it's the question. You really asking.

B

A

Not Bob, it's just about the names right. So, for example, we already said we will have bytes available and what's written yeah. The question is just if you're the consumer of the API, and you write this outer loop. That has to determine when to call you know, move to and move to a sink and flush in the stream yeah. Then our current model is that you're thinking in terms of oh I need to do this periodically, but use the whole much. My array buffer has been filled as a hint went to do this.

A

That's what we use terms like no bytes available in the buffer right, but if you were to think of it from a point of view, like oh, do I have everything do it? Do it have something to write now, do what you would call a class before me? You would say something like you know,.

A

Yeah, how much data is there for me to write for ago.

E

And in that same thought that um when advanced is called because you don't have a big enough buffer, is it filled to the exact size you need, or is it allocated more because I would have kind of affect how you wanna, you know, call flush or not call flush.

B

E

Assuming advanced did what does it do then? If.

B

You're motivated some data he wants AI would be within ten hundred bucks. That means you already had a hundred Vice in the opponent's offered right, but.

F

What if the user passes in a value that's larger than the buffer? That's wrote: okay,.

B

Come on Sparky at the buffer and you only advance what you've written, which is you get this? The pattern is you get span? You call gets bad. You get us back to right into once. You've written some data into it, go ahead, man to say, I've been to annex more data and that amount should definitely be less than for the best matter to you, because how are you and dividing.

E

Okay, for some reason, I thought it was a girl boom is.

B

Expanded memory, so it gets banned and you give a size in, and you say one being it doesn't have a million and it's feasible for you to grow to 1 million. It might give you something like I'm, a gay or 1 million.

B

I

Is my size, it.

B

So it's not guaranteed to give you what that's an official data provider. That's unnecessary part is a PMF I mean yesterday. I was following it ties. Name gives you, gives the I online intimidation and of how much the user requests and you can give ie between greater zero and that's not equal to the size. I.

A

B

A

Five anything to be back in million yes, but if asked for five hundred, even big to that's also possible, it's also very you just can't give him back an empty bucket. Yeah wait.

F

Wait so that's all you can say get span and I want five, because I have five bytes right and you can give me back one, that's two and then it's going to fail. Yes, that seems bad.

B

This, so it's not me whom side! That's, not sighs him really, because a casual usage little bit simplistic design. They require double it or not. You don't have that strong contract. It is, if you ask why you.

F

Have invited seems like there should be an option to say: I. Have you know this much data I have to write this much data. So therefore, I need a buffer. This big right, because otherwise users are going to have to keep requesting again and again and they're not going to have any escape hatch for oh I'm, using a buffer writer and I actually have this much data I have to write at once. Well,.

A

Then, mr., what do you have in the pool right like if you ask for 4k right? You may have a 2k offer in the pool right now yeah. You would rather fill this and then ask again for 2k then to force the thing to allocate the fork.

F

Right right, but that's why I said there should be an option saying that's my shadow and it I'm afraid yeah.

A

I think in practice you will never pass in sizes that you just said it's not that you want to write an incan you asked for for I did more prep, you very likely to ask for a much larger choices, in which case you're very unlikely, to write.

F

But but that's also, the case of like the user says I need like an 81 K buffer because they there they know that score. That's the performance metric for their stuff right and you give them back something that contains 1k I mean that they have no way to be able to say. I, definitely want this, and and on the flip.

A

No, they do look, it just means you have to do your own pooling like if you have super specific requirements of what you want and your you provide your own eye, buffer right implementation. That does the pooling the way you want money.

F

Well, that seems like the case for from the get-go definitely exposing the constructor that takes a right cool, so this thing will do what.

B

You ask them like, if you say, gets man you maybe like a little bit. It's just that the interface does not require groups. Oh.

A

Like it's a only similar length to the week method on on stream right, you say read, give me two: okay, I, give you a 2k buffer and then the thing gives you back a hundred, but it's not done yet right there, just because the hundred was just conveniently available memory, I decided on a block all right, so that's it similar, isn't like it might be inconvenient for the caller, but I think the problem in general is when you write your code, you have to handle the fact that you're writing more than what the memory currently has, regardless of whatever whether you've lost in your life in sides like the contract.

A

I think in practice is not actually constrained on you right, yeah like you're, normally loop will just handle that case. Just fine, but it.

F

Is there I guess on the flip side, if you have one particular case where you have to write like a t1 K, but then the rest of the time you have to write for K? Is there a way without disposing the buffer to be able to say, I want to shrink the backing pool that way over all goodness for the GC and for being able to share that buffer with other people without actually.

B

You guys people find.

F

You think I'll fight through the girl besides, that I know well not necessarily fine tune in that case, but to be able to say, I no longer need something, that's 81 K and can give it back and give me something that is smaller. You die before that you're done.

F

I would assume that any such shrinking method would require that we that the user did copy to in the first place, meaning that bytes available is the entire length of the underlying buffer, basically put a requirement that the user has flushed it, but be able to say you can give this one back and give me a smaller thing all right and if there's a scenario request for this future.

B

I don't adjust that mechanism well, what Hubbard data you're creating and whatever could be a act as a beacon. You should like only make sure you especially everything already if you have okay.

F

Is the the scenario would be like I'm writing a bunch of of Jason data and most of its small? But then I've got one really big one right and then now you until you dispose. Yes, you you're hogging, a bunch of memory that you don't need to be hogging.

A

So it seems like we're kind of question.

B

Okay, I was on this output as many oppressed and easy I was returned, what you've written so far and maybe expand. So if you want to be significant, then I, like the name. Yes really.

B

It's basically a view to the unlined over, which is wrong, then, from 0 to 5 rating.

A

Or maybe Manson's not polymeric,.

A

Output again, we might be more problematic because.

B

A

The main reason I guess I.

B

Think you can stop right about the main reason why we have output s in every is so that someone one can call puppy to a stake of fascism on the street they can take is outputted right at issue.

B

And steam hissing does not have a Spanish hole.

A

Because, if divided racing within the earth, it only takes movement, that's right.

A

G

A

I, wouldn't thinking about is this problem that we had with memory stream I'd made me dig the underlying array, like you, can yourself pretty bad, but.

B

In this case, better than I already I mean it could be yeah yeah, yeah, you're.

A

Just leaking effectively, and then you different you over that, so that you still.

G

Buy this be right, so it is readwrite part. At the same time,.

B

Because there just wasn't rolling.

G

It only to read would be weird to so I, don't know.

G

I mean you could buy to the span right and then call advance from you can still make the scenario of work. If you really want to write to.

B

No, this is bad, it's going hey the team. Just that you have you do not. You do not need to write to it. Then, the underlying writer, nobody.

A

Violence for openness, panic until the right to that span using some API that expand and then just advance for right there, just with four bytes to your underlined all right. This.

H

B

Yeah but I'm just saying like if you wanted to get you some online rider right data right and you want to say, give me the date of your written. So then I think now I, don't wanna call coffee I! Do my own stuff! Wait! I need this. You know.

A

That make sense, as I'm saying I mean in that sense, you could just constrain it. To read, only spend only memory right, also yeah, all I'm saying is that it doesn't buy you much because you can still safely right to it. Assuming you call advance yourself right, which seems fine.

B

Well, I would not like.

H

So neck is: why don't make it we go in this fair.

B

A

But all I'm saying is that I don't see a reason why, if you would just allow a defect, if you do it sure you just have to call it that, but that's basically the way I before itit works already right.

B

You know because this is actually telling your view into what I was already bended, if you're not ready to advance you've crafted a few days ago. Oh because.

A

That's literally what I see when I say: yeah: it's not yes! Yes, don't do that! Okay, make it your own. It makes more sense how about the name find it all I. Think I'll, put a square up at this moment is read-only and seems fine. Okay I mean this so far. Much of maybe that adds. Maybe it doesn't I think you say, output right so and replies it.

A

Oh, what's that should.

F

The outfits I have already been written, be read only because it implies that it would be incorrect to modify them yeah.

A

I just said like it seems like you, don't want this to be right because you literally divided over the stuff. You just brought yourself for.

B

Some reason I couldn't see- maybe I like memory that can you confirm that the Richmond stream dot right.

A

I think you're right but I think there's an unsafe cost. You can do it's.

E

Just scenario for these two methods- own I mean just you, the Daedric you've already written.

E

The scenario um I mean: what's the real-world scenario, for trying we're looking at the stuff, you already wrote: what is the scenario.

A

It's basically, if you want to do your own, basically own version of copy, to a copy to a team right.

B

Also debugging, but you want a nice little girl are.

E

You, okay, okay, yeah! Otherwise, you, okay! When you call get me a marine gets pani, I, buff, right or you're just getting the forward memory memory, the inverses.

D

Oh I'll put its memory.

A

I had the same confusion, I.

E

I think you want to rename these in some way done.

B

E

I, don't know memory written spam, written or something I, don't know.

A

Invites written as memory buys written in span I mean that's pretty much I.

E

Have two really quick things: one, the class isn't sealed: I wasn't sure if it should be and then the copy to a sink I, don't know what the deal would deal with. Task versus value task is anymore. Is it an that standard thing or you know, I thought belly task was recommended for perv, but I.

A

It's a good question so that started with the first one, so I think we googled it. We don't want to call the copy to what you want to call it something else that implies the move right, Oh Pete. You should be.

B

Even move to be not wait for the name or some sort of thing, then, if you get this all superior copy.

E

A

I mean to me move I mean the only way I can think about a move. Is that yeah you reset the other one right like I, don't know, I mean I, thought it would work, but I think you would call it send or copy to then. Yes, you need to include some sort of like, oh by the way, the data will be gone on your on your from your source. Right I mean I could live with clear and copy hook. So copy and clear the clock would be bad, but copying clear seems fine.

H

Between here and copy.

B

To clear, and here is it.

G

Coffee and clear mm yeah copy and clear so.

B

We drop the boom.

E

Baby, it seems like copy async and clear I know it has the end of the day you think, but the clears not a sink.

A

Yeah that one is one of those things. That's like I, don't care. The convention is more important than the yeah, because I mean that yeah okay I mean, if you think about it, you can't really don't start the cage racing with me sensible. So that seems fine, but the major task one is a good one. So should we make copy to a single tournament, it has a very task.

B

A

B

Don't set your do it.

A

B

The task finishes synchronously. There doesn't have that okay well.

A

That, but also like you can you can do the new, cheaper one if you wanted to whether we do even the ASIC operations and cheaper way, but the whole go with what's called the best in you, I.

B

G

B

To do I perform it's just even and if that, if he's fine with it.

B

The other thing was default argument, except there is no longer 2 is negative. 1.

E

And then did you say the class should be sealed. I can.

B

So I don't see any reason why someone want to yeah okay, otherwise.

E

I think the dispose as a pattern neuron correct yes to a.

G

Virtual Buddha textbook.

B

It's to the trap, what was the constructor one-inch.

A

The capacitors.

B

We said negative one as a difference.

F

Or later, or if we don't like negative one, then a in overload that takes no parameters and initial capacities, not people, cuz I know some those going to be back before of negative. One is a bad default value.

B

Equal to zero people, I am I, also wear it. Oh means I, don't care just mean whatever yeah. So zero is fine. Some it's some sentinels to indicate. Yes, some.

F

Say no that hard-coded here so we can change in the future I needed.

B

Because you nepali mix, that's true because I don't want you when you use a negative value and yeah yeah I mean.

A

I only say that point just have two constructors one.

B

That doesn't have anything and.

A

Then just set the dynamic value.

B

That's one hell of a show: I mean.

A

I think mr. capacity of zero would be pretty close to non sensible because you like, why would you serve an empty buffer at that? Make no sense? Yeah see you I mean one of these implants. Typically, the size is not minus one. So that's some other radio right, but the zero seems bad I mean personally I don't buy the argument that default parameters need to be defaulted to default because I mean the whole point of them is that they show up in intelligence. They show you what the value is.

A

So if you don't want to default, it's.

B

Just about there you're making the internal energy to the public but saying 256, yeah.

A

No I grab somebody by that. We don't want to need the actual radio, because then you can never change it. I think in practice, though you might find you can ever change that yes, but that's a different mode, because I mean it once you have like once once. 256 is widely used and now you've changed it to 4k. You might request perf left and right. Oh wait exhibit different race conditions, whatever I'd like that says well,.

F

We already have the case that 256 is is guaranteed. I least in this case, provide at least 256, but it could give you more so there shouldn't be a problem with upping it, because it's already the case that you may get more than what you asked for yeah.

A

I'm not saying that there's a violation; in the contrary, all I'm saying is that there is a problem and gentlemen. We mess with things like this mm-hmm because it turns out that, even though nobody have it as an extra second, you know dependency on it. You change the flow of your code. Now you run through multiple times, you allocate more memory, and that might be not what people for do what you want right.

B

So so one thing I wanted to talk about Christoph left is how we distribute this library. Are we shipping it because today you need to run in order to put it in the system buffers assembly? This is the hyper violent know, instead of memory or certain buffers wherever there will be him for something by me, you see here is a JSON writer in Turkish nation of the world. So what should we do around thanks? Ladies of course, it up music.

A

This is the whole whooping discussion again I mean I, don't know to me: that's almost orthogonal to API design like I would, as I said, like my general rule of samples, we started with assuming it's inbox and then we figure out after the what would need to happen in order to ship it down level. Okay, so we put the tiber everything it should be. Yep.

B

But for this type live next to the interface I before either ie in certain memory or surely legitimate, remember gear assembly, orphan living system operating there, yeah.

A

Am I making about the difference between the two is.

B

Just two separate Sandi's in terms of live system buffers contains a pool and see consider people. Let me pour some.

A

This is no memory, is the assembly where we ship spend on other right, yeah.

B

Yesterday, memory contains span that days I before at this interface I before I, do that I see only sequence and encodes entry, no ASAP as like it used to cut it, is a partial formality and operation shadows, a couple things that we may have tried needed now as well.

A

But that's I'm, saying I mean like most of the times that used to be in their type forward to zone right, so like they'd ship. This.

B

Is not really super sister about all usage special method.

A

Yeah I think as soon as you've, a partial for sound for your school. So if you, if you really want to do you only do down low down low, then you want something that you can actually wrap, but.

B

That you don't have anything like.

A

B

Because I mean the buffers in box system, buffers and boxes and everything box, so they both are a budget or something.

A

I think for full family for me doesn't matter which one you put it in, because they both encore the questions. What do you care about? If you want to be abundant neck or 202 one, then it matters, because if soon as you have these partial facades like you, can only update them all of them.

B

My my assumption is system memory in certain buffers are both proven and they're, both only being extended for three roni I see so I'm, actually before the not the most typical place where this would go, then.

A

I would just say: I would put it close to where we put array buffer, sorry, I right.

B

Cool not next to the interface.

A

Interfaces in lower, supposedly right or higher, the difference is higher than we cannot put it lower and it interfaces lower. Then we can put it higher I think it's.

E

A

Plan seems to be low enough. That is all I'm saying: okay, I, don't think need to be lower than I'm a fool. That's what I'm saying and inspect you probably can't, because you need to call it the rapist. Yes,.

B

A

B

Buffers get all done, you.

H

B

You can put things in sitting above the namespace inside yeah. We.

A

Have no word on that, like pain, spaces are organizational and writing something.

B

A

I believe you do.

B

Oh, my god. No, it's just! Oh yes, sorry believed instrument.

B

B

B

Anyone else have well.

A

There is like a fuckton of common sense: I looked last time, trying to read them now, but I know they're, just pontificating over Nick's use of VF. What use of you.

A

So ben says it should be tossed no value task. Okay, because tasks are completed. Task is faster than major task. Wrapping a task.

A

I, wouldn't repeat, and it would just be the complete major task, but the only reason why I said when you task is not so much me. You not allocate it in either case right, because you can always have a completed task. They don't have an actual t-there ID speaking all industrial, but the thing is that the only reason I said major tasks was because we we now have an ability to complete a synchronous operations in LSL, okay t way, and so that that was I. Don't know. This relates to video.

A

This is where the task of T, maybe the band the gains- are only the way the task of teen or I ready tasks, but I thought it was also for beta test cases where we completed synchronously. So when we added.

B

It yes, our district document, the turn task it. How many times have you decided them not so.

G

Well, the V explicitly decided at the user because that just being over sin.

B

Are just one method is pretty simple services.

A

You, whoever is asking what fool well, the eraser you are allocating here, are coming from the rape. Alright, you know you know what new in a brace yourself and then, when you grow, when you just return the current one, you get a new one right. Oh yeah,.

B

I definitely agree with to stopping that. We do need features around streamwriter. We need the operator feature, our sequence, writing or whatever it whatever. You want to call it perfect extreme case: oh yeah meanie, a stream writer, that's directly right into screen, so there's mostly about what is doing. You need a buffer right of it actually allowed into mice.

B

I prefer a vortex, but I prefer it unless you turn have to use not worry about that past when you just back so that if I start with evil anyway, it's a good buffer I do a friend up and say you hate one right end. You tell me right: I'll do that.

A

Oh I mean an actual one that gives you like convenience overloads that are actually sensible to the thing you want to write rather than you have a span and go party.

A

So what happens when you need to grow the array to something absurd that you just stopped using the array pool or does the way people handle the case we asked for a waiter waiter, we started.

B

To forget by the way throws we will not look like one of the games. Sorry.

A

I'm just saying some of the Earth's sides, I'd say I mean: do we actually pull away? There are two big concern. No fooling is this one I waited, and so once you grow beyond our.

B

Necks are advocating that intercepts are navigating the.

A

F

E

B

A good example: they exhausted right.

E

B

You say: loss to the food yeah.

A

Nice concern was there because you're fake when I'm a fool and you write something absurdly large, you didn't all stuck with this thing forever, but you're saying no. In that case, the pool just.

A

E

Just start question: if I call I get memory twice or whatever good memory and get span combinations and has some same numbers just gonna keep returning me the same thing right yes, and if I pass them something a little bigger, it's just gonna blow up. If a can, it's too big stuck in a real.

B

If you pass a song, as you subtract, was presently to large janna to grow up right, otherwise, no Oh based on size and if.

H

You just say: get stand without.

B

Sizing yeah just give you where it has, as always larger and Android.

B

E

What do you mean by broad I mean you, it has a it. Has a buffer under the under the hood? Does um maximum it won't grow automatically right based on another conversation,.

B

So if you keep calling against man without a sized end, it will only go up to a certain threshold and stop doing yes.

E

Okay, if I don't pass any any size hint, it's just gonna give me everything. No all right, but they're.

B

Also I'm gonna give you everything just give you whatever size. It has.

E

Oh okay: well, as my man, okay,.

E

So I mean that's a method, I know: you're, the ones are properties, um the ones I'll put as memory ones, but I don't think it matters, but.

B

My guest banquette memories are messages because they would resize. This means the access operations. Therefore, we do not bubbles top quiz. Many offers parent little slices of the underlying buffer, so they are very fast operation. They are not doing. Any reason is there to anyone, just giving you back already only new into what has already been written.

B

Is my banana book.

E

Okay, so every time you call get spanner getting buffer you and you call it again- you're gonna, you might get back a different person right, so you shouldn't keep those wrong.

E

B

B

The fight fighting is like around some finally adding cup of coffee to API. If I use a pasta to your stream- and they just say you do- is writing together. You don't want to say another right, I hate when you write good and here's some that I've written something about you, try to get up.

G

Yeah, that seems good bad.

B

Because the user, I guess and as I mentioned detail from their respective- and you said murder than that, you can use right.

E

Yeah I see no I I know you had an implementation of this um already so I'm. Just taking a look at that.

B

One thing I'll do as one of his five issues but for librarians reminder right.

H

B

Least, just wrap them I, don't have a proposal for the network yeah to Chris's point or like. If we just completed rope the ball on this one, it was either the Islander misses. The point was we'll just read it later, which is negative value requirement before I ever created an additional item, no not required it. So therefore, there was no strong scenarios to push for this.

A

You directly you type of yes.

B

A

Right so, unless somebody else has a question that I would call it day, I want to do this for half an hour, but it seemed that we were sipping difficut in or what we can do is that then I think consider this type of proved, with the Thunder feedback that I have yeah and then we need to I think as follow-up. We should just.

H

H

G

G

Generally, look and that's offer a reader Karina, the meters. There is positively.

G

Hoping that JSON baby.

G

But I'll sing it early all.

A

Right awesome, the nodes and then move to more fun stuff next week, I think next used now. Do we have significant find on Friday I, cancel everything because we've our glorious, All Hands and then on Tuesday. We have another one, our attempt at Levi's API, which last time we said will take an hour and we took it in a full hour to just review it. Half of the first one yeah you'll, see well.

B

A

That's the other thing: I want to do the triage next next Tuesday, which is why I, unfortunately had to decide the device thing is still an hour. We do one hour of triage one hour of YouTube, a goodness and then on. Thursday next review will look at Part B, the typewriter that first yeah, the stream adapters and then I think the week after we settled for of these Jason see you later. Okay,.

H

Cool thanks all right, thanks guys.

A

I took this correctly.

G

To Boudreau didn't turn hi folks.
