From YouTube: .NET Core Design Reviews: Portable PDB

Description

I this meeting, we'll taka a look at the Portable PDB APIs in the metadata reader.

A

B

Of ourselves to recording yep.

A

Recording it in broadcasting at the same time as usual, so let me actually project the screen. The problem.

C

C

On that button here we go perfect.

A

All right Sonique, I pinged only it's better and.

C

A

Give us a quick over you because you've always the best person to.

B

Do that, but I'll try to represent this.

C

Work as best we don't come yeah. We.

A

Did like literally like 10 minutes ago, maybe.

C

Compared to go so basically.

B

What this is is a maza compiler can now generate debug info I'm, a foreigner format that basically is exactly tables and metadata, and so the reader is implemented in system reflection, metadata this style of API matching matching the. So, basically you can see a whole bunch of new, like anything that is the flaw with a blah handle and a blah handle collection is effectively just like everything else in system metadata. So if you see all the other types or you know, there's method definition for, if did type definition type reference.

B

Any references are all tables, each of them on the handle and then go from the handle to the to the to the record. And then you have a collection of these records. So it's a very like there's do a lot of API, but this is very uniform, like you know, each handle Austin moment, conversions to the you know, general candle, but.

C

Basically, the idea is.

B

There are like five or six new tables, and then I will be useful to sort of call out that there's a there's, a specification for that. The rosslyn team has come up to the iowa-based delicious. Well, we might really be part of this specification at some point. Right would be, we would say, like a fanatic is extension. That is enough. Where is my cross.

D

Issued was just adjusting our.

B

It really shouldn't I mean I, don't see why I would but because you know it's just like exes like new, like I, mean.

A

Like name collision so are no.

D

I'm just warning at the actual format of the actual binary supplemental life, we're.

C

Putting it in an extra.

D

Table for that extra so take sounds like what there's.

C

That your teeth are gone because other I.

D

All commuters, but all understand the stables you have to come blow.

C

A

C

Is requesting like Janeiro of PDP Phibes? No we're not existing PTY. You do not are such as ed. There.

B

Is a bridge that the moss rose is not separate from this review that if you got it gets gets you if you get a Dyson reader, /, affordable, PP using this, and then it implements the up api out of the so you can. There is a bridge.

C

B

Hope I don't know the details there, I really Commission on secure so because.

C

It's so because it looks like redness. Why do we mix tape the ethics with PVD, because I should be me? Basically sympathy PMS from.

D

The metadata good.

B

I think because should they be separate API, as in um like I mean so basically like the way the format is designed, ends up being super efficient, a lot but I mean basically, we have all, but we it's basically like very uniform. It's like it does.

B

The PDP mistake like like, like a in terms of the ecosystem, having an just equally standardized way of getting given given like symbol of the symbols, are basically you don't want to get the sequence points, just like more information in metadata like but, like you know, we can put in a separate file or in the same file, but basically like I, think it belongs in the same library because, like it like it's a missing part, because it's like you have it standard, like is still I standard. You know metadata format.

B

We have, you know an open source implementation for a reader of that format, but we don't have this. What we don't have is like the symbols right so like putting it together with this is like basic, basically show you there's a there's, a few mins. You get the personal it's just because it don't it's so naturally like exact same pattern to access it as the rest of the metadata and then.

C

It's also understandable, isn't like let's say we want it to somebody, one you to test party PDP and related to managed metadata. It would be, it seems.

B

Like it would be awfully what you need by unrelated to Madame, like I, think.

D

They're, pretty tight, sorry I think were you actually if I correct me if I'm wrong, but if the portable pdb actually uses a lot of the meditative pieces? Those if you actually use tokens itself directly from the aisle in order to go back and forth and forget.

B

Jenny tells the format to be honest with you. I wish the muscles here, but we can go through the handles and see what foot go through the definitions and see which tables they reference, but it also really get to click through. It seems like these PDP's.

D

Would be able to be lots more than our old herbs, they.

B

Are connecting they are especially.

C

D

Can you do you can want to duplicate any data Lydia.

B

A look at method, body, okay, so, okay! So it's just a second point. Well, you need to look at the suspect for something this okay, so um so.

A

What dick! What's the cushion again? Because I think it.

D

Is whether or not they do they need to be tightly coupled to the aisle netted a reader or not mark commission should it be shepherd I think.

B

Like meaning in a separate library is like kind of like first of all, like regardless of the.

D

C

D

Duplicating a lot of the similar names I think not or use it to Beijing present reusing things from. It will certainly reusing.

B

Things but I'm trying to find I, don't I mean I. Don't make any sorry that I don't have the so.

A

B

Gave it a quick way to digital lega.

A

Was duplicating I mean it had to introduce a bunch of concepts for sure that didn't exist before, but I mean most of the stuff.

D

A

Know you need documents, obviously, in order to represent that it needs some more things from the actual IL which we have an exposed before, and I think this goes with method definition as well, which I believe a method. Barrios didn't exist before, but it took pretty much like what you would do when you would.

B

You like GT right there, look at the kick this machine, so this thing is a method definition. So right there, you have this disability to tie debug information to.

B

Do method definition ample.

D

C

Doesn't mean that you.

B

Can't have this in a separate, API southern new space. It just means that, like I mean.

C

I was thinking when something extreme, like you know, other blended to like c++ if I'm seen. Okay, oh that's like I, don't think that's in scope here! No, this is I mean there's the whole.

A

Point of this is to basically no I have to have a separate file format right. The.

C

A

Point is to make the pdb s an essential part of the ACMA 335 metadata specification, so.

C

This is surely.

A

About managed code there's nothing to do with C++ I mean you could.

C

A

That you have a fake, you know Eknath with you, five compliant binary that just doesn't have any code and it just uses it as the debug storage.

C

Engine house I have scope, but I I just wanted to make I think it would. It would be possible to implement basically a generic PDP leader and then the ridge idea applies to our metadata right. So.

B

We kind of have like, like again I'm speaking like very indirectly herb I, like you.

C

Can definitely imagine this is a low-level.

B

C

B

You may be able to use it. You know, however, been then you can certainly this.

C

B

So like like what what is available today already is, this is the low-level thing, but then there's already purchased the existing PB to be kissing. Gd P Dyson, an API solar here like I, mean.

C

You know, but it's kind of similar.

B

In the sense that this metadata is some reflection metadata and linking them through awesome, because.

C

B

Is very much behind the scenes. It represents like the ability to read the tables from, and these are just basically more more tables in the exact same, the exact same sort of style like it like whether.

C

B

C

Might want some.

B

Of the tables, and not others in given scenarios like I, think it's true, but I, don't think that's necessarily like it like needs, really makes a big difference in terms of the in terms of like splitting up the API, because it's.

C

Like very uniform API, it's like.

B

These are the tables on for each table, there's a record that you can get and like I. Don't think that, like dicing up that very low level like give me, the tables like into like different is like really buys you much in terms of scenarios, because it's completely like it's just.

C

B

There's a definition is like these are the tables. These are the schema and it basically you know, gives you gives you the records until like we can split along those lines, but basically the implementation and underneath is going to be exactly the same answer exactly the same style.

B

They need the same like they need the same low level like bit twiddling code to get around move around in the table and so like I think that if you want to like make more data, regardless of coupling just like just generally have more data in the equity 35 style, then we should like reserved. You know records for that data and add it to this API I, don't think we need in API is I thought at that level, but once.

C

You start to get a higher up.

B

You know, like you, you know, you know this is not the API for you, like necessarily. If you know you want to sort of build something higher level, but I think in terms of what this library does. What's specifically also, this namespace is like it's all the you know.

B

It's all the records and so I don't really see why we wouldn't just you know if you want to use exact, same sort of database format with the exact same, you know we table readers and headers and all the rest, then I don't have a problem personally I'm, just adding naming the records and put adding them to this API other thing: yeah, do you? Have it go samples? It's just like basic usage of the new API.

B

Unfortunately, I do we know who using them yet is it it's.

D

Rosalyn, because very comical.

B

Is not is the expression on the waiter is using it primarily right now. What's.

A

To what took away everything that.

B

Gets access TV that and use that's been done in this format instead of global program pain, but there's a bridge to this format, as I understand it like, so that not all the calling code, s like like I, not everyone who needs to access, affordable, pgps, to go straight through this ticking and go through existing API, have been rich over this. But I, don't know the details there, okay, right they've,.

C

Got so how do you block and you just write on the board like how do we get started? How do we load you.

D

Look like to feel.

B

C

At you know that reference is simply in the not love but like open reference send via.

D

The PDB files, not the references from the actual musicians, yeah.

C

Oh yeah, so you opened the implementation, this MV and the pdb file and you okay,.

A

Let's, let's step back for a second, so they always say portable pdb. This is replacement for pdb pdb is a specific format. That is what is written by c++, which is not cross flat. So the whole point of that this is basically merging the debug information into the same assembly with implementation lifts not as aware as in.

C

B

C

Some more reading, instead, we did, as I understand it, actually can you bring.

D

Up the strength here, yeah this plant, let's go for it look, is really helpful and honor yeah. I don't actually know if it's all and where's.

A

It is it and is it wasn't or is it in ours I.

D

Think what are the male's helping? Click on it? 10.

A

D

A

D

D

Implemented api's in valuing this way, the.

B

Violent one watch carefully: the red specks want to make sure.

B

D

It doesn't need to be Stewart yeah.

C

D

Is stored in the same I? Aha, that's why we're asking my initial question, which is: how does how do we not trip up existing aisle at an inn, Jewish and while they should be ignoring the tables into a new table? Is.

B

Like basically as I refer remember at the beginning, tables are like, like they look there there there's their election or they're like the ages. We have an index not like it's really.

D

It'd be interesting to see the size of this out the differences so volatile.

B

It be interesting one thing, that's interesting, separate file or same file. The pd itself is much smaller like then, the whole form.

D

Again, giving that most of the opium is actually containing the whole copy of the eye of fish. So once the extension.

C

It's a separate file is it the same, probably that's confusing to two different format so.

D

Okay, so in such as.

B

C

B

C

B

C

One it's a separate file and I assume like you, can open both sides using these it you guys, yes,.

A

C

The same API and say which would make it.

D

A lot more ships, whites in the villages, pardon.

C

B

Right- and there was you know, we could see the cross referencing but I, but imagine.

C

That, even if there are two files, it's just like.

B

Listen I, don't.

C

Think that it's a new format it that's it like the old PPD for life has nothing to do with the correct we just pdb. Yes, save me yeah.

D

I say: purpose EOP program.

B

That I've been it's like I, don't know we got seems like in fact I. Don't think the word portable pdb occurs anywhere in the API, so I think that can be discussed like thank you. Nor does the reader care about these medical plans. So I think those are things that you could follow up with with the rosslyn on, but I don't think that doesn't easily. It doesn't.

C

Really affect this.

B

Because if you basically talk about the records that you see here, and then you open a thing, you just take a string. There's! No, maybe there's no there's no notion of compile extension. Do we expect it.

D

Almost will always always be.

C

D

B

I don't know, I think the opposite, but I have you have to check with Rosen on their angry with expected. Actually.

D

Don't know that would also mean there's has to be a lot of Christians of providing better, not I, think they howl I.

A

Mean already have searched for.

C

Pdp to I know that they already asked his wish to say before 91 yeah, yeah, I.

B

Don't know that I don't know the details of the switches, but.

A

Yeah I suppose they do the right thing so.

B

Like I think it might be useful to go.

D

I think that's a good decent over here with the basic ideas, let's just kind of scam through the API, to see. If anything, she won't flip on us, that's kind of what we want to get out this way. So.

A

I think we should we separate mandate here at supposed right, because it's kind of like the poor time, so it.

C

A

C

Here you can basically.

B

Chance k, there's a collection of handles for each of the records like you can see it coming next to it like this, gives you like the one on top that assembly references gives you all the assembly references. It's basically.

A

C

B

C

Only reference table yep.

A

C

Collections just like special types and not a list of craig ooh ah perfect, so.

B

There's like the handles instruct the collection is a strong. The everything is everything. Everything is basically.

C

From its been chewing like and we go create a general-purpose charts list, let's go chose all that person. No.

D

Not with the to.

C

Extract just of tea, you.

B

Know like stroller I so proud to put of.

C

B

A

C

Would have need some virtual.

A

That it would give you like how you jack- oh you, actually numerate right, need something that actually does information. Whoa.

B

A

I can't give you a generic collection dead like how.

C

Would you do that because you.

A

Don't actually allocate the thing my you literally just enumerate.

B

The format as it is that's the thing: that's right! That's right, yeah, that's right, yeah, that's right, sorry, acid or sprinkles, yeah and there's a lying. The tea is not there's nothing to do with T. You have to know, particularly above the table, about the yeah, so kamik engineering and there are works to some of these enumerators like because they each have known code. They.

A

Probably do something really ugly, that involves a bunch of split no.

B

That's still like, like.

D

We're just follow the same pattern we already have about the.

C

Value over here yet yeah.

D

We did a bunch of performance of houses, originally I'll noticeable decided my great great, but.

B

I just yeah we'll work. It certainly makes the guy bar.

D

So what is the document in existence of affordable baby wasn't done.

A

It's basically a brewer typepad right to the to the actual source file.

D

Okay, so it's a sort of all done, but.

A

It I think it has like some I mean in your pdb. They had like a GUI that involved the language syntax. That's why the Thea that you know the language there.

C

Was some good that.

A

Represented this issue of this is VB or whatever I'm, not sure they have that in here as well, but I think that's essentially what it all communities you look at. The document definition I guess.

D

There's a language group yeah.

A

Here you go so same thing. Can.

D

You take that handle blog and let you pass it to the rosslyn API to get a syntax tree from. If you had a horrible.

B

No, but you can get the string, ah maybe I know they're also an API but I'm. You can get.

C

You do the same thing that you do with any of these records.

B

Say you always get handled because and then you go from the handle, you go back here and meditate. Every turn see you.

D

C

Give me the sorting that goes with this or give me a.

B

Good that goes with this, and.

D

They all have that we all have the same.

B

Pattern so um so I guess it's like a.

C

Micro thing, but document is a pretty genetic mate. Yes, I was just okay, I wonder if each industry source document or something like that I. That's that good feedback, yep.

A

29 here, a touchpad is crushing in its really annoyed if I want to use this.

C

A

Nibble here, which I can operate properly.

A

And what it mean when you say I said.

D

If it's not solvers, it looked like, it was really meant to a pointer to this into this much time. Maybe yeah.

A

What do you think it is.

C

A

Have this effect, everyone.

C

A

Mean this is literally they just.

B

Click on that. Listen to this page, one.

C

Okay, so this is document cable. This is so unstable, but it sounds like fun thing. Is it natively? Let's see I think so,.

B

C

Right, I think what I mean, I think.

B

The terms here, you know pretty common, like if you look at like CCI a look at like anything like this. Coming from the TV, I believe, like I've, heard the term document be the thing that symbols refer back to call it argument, but I mean like so there's some history to general yeah. I please my understanding, but I don't think that music am here, I mean.

A

Table I wouldn't add in here, because we don't use table anywhere else on our table, but I mean most.

B

Of the things are we here at inside yeah.

C

Right, well, maybe we don't need to invent the name. Also wise. Their property is new. Every single handle houses so.

B

Handle is basically very.

D

Similar in spirit.

B

To metadata token, but slightly abstracted, but underneath it's just an integer has basically one bite for the type and then the remaining bites represent the row in this table in the table right. So when 010.

C

B

Or total format, when the real point record number 0, it means mill so like me, like you, can only have like. Oh you know give me the way to handle for your this or not. So you know I'll have one that was about the name. Why do you.

C

Suddenly, just removed from that new also.

B

A 10 on doll is a non-null struck and he'll is the terminology that mean that that's what it's called in the inequity, jihadism know and I understand.

C

We already have these properties, we do any.

B

Other hand we do but I think that it actually we went back and forth in the original review and like is null, is pretty bad because it's not null and then his default is like okay, but like there's actually turn in the competi data for the system, Milt, Okun, Joey. No sorry.

A

It's better than its dummy, it's better than is dummy in Jersey.

B

I don't like to know it's like no, but for this particular kind of thing, if.

D

It snows is it actually valentino scope, no.

B

It's not about it's not valid in that whoa cuz I, don't like on.

D

Our seat pedals are good, we have is valid brain and it's.

C

That is a section.

B

Yep anybody is zero, is reserved his your Windex is like the nil, like not a not a rectory index, and one is the first. The first light thing: yeah.

A

C

So then that's.

A

Actually go back to our editor reader if.

C

I can find it that's right.

A

All right to say that this.

C

Screen is not large enough, so.

B

For the next one, so I talked at the multiplier. We want to change custom, debug information to custom, debug info and method body to method debugging book, because it's not a really good method body and there's already a method body in reflection, which is quite add one for the one. We do you there's actually two and there's actually not the body block method body exists, but they refer to actual body of a method. Whereas this method body refers to debug information on both the method body, so I don't know. Okay,.

D

I think that mission, so I do what.

B

The short contending all because it's getting long because it's going to be method to before so we wanted in for custom debug information is fine, but I wanted that to align.

C

With so method body.

B

Has to be renamed, that's a method, debug something method. So.

C

You said method debug info.

B

But then it's weird, if you have an information and info right next to each other method, debug information that you have method, debug information handle collection, do.

C

Realize but we don't have guidance. This is hope. You know if the name is too long.

B

Dude, this is a sudden, a space of reflection, yeah.

C

My reference all info, okay, that was no.

A

Because I knew that.

C

A

How I do about.

C

Residency vinings. We have the access info, but I did I think, to do you know yeah in.

B

The namespace info suffix is pretty common, so I think that's looks like wine. So what did you escape but ideally that, although we don't have guided because of the patterning here, I mean we do you don't suppose we have this guidance, but you should have some kinds of life. There comes a point where there is like quick certain from making greevey a shin, especially as we've used a lot like, especially when things are getting super long info information I, don't think as a lot of confusion, factor.

C

We can look at it as we do and show it means it's not one of those all right. Oh.

A

But you can totally pick shorter terms, sure.

C

Or even you can you can pick initials out shortly then I have to do research on the terminology around their iPad abbreviations. I. Remember.

C

Okay, good we're here we go.

A

Right so what is cutting give out information? Actually? Because if no idea, what it actually.

D

Like it I guess is tagged, it didn't renew it, so you don't forget, but yeah I don't know what is easy when I was sooo much custom attribute I think these collector.

C

Kind of bothered me I'd see it will makes it.

C

B

Pretty fly me just looking at this team I, you kundali, you can put a good associated.

D

B

Any entity meaning any table in the metadata and a blog I mean I know it's pretty much a way to mention I mean you can touch, I mean just from that. You have to read it, but you can imagine that the lousy touch any blog thing. They do. We have any entry.

D

Do we have a custom attribute type thing that does that connect same thing? Take.

C

Fields, custom attributes are very specific area, and that is just sufficient. They have do.

B

They have to say which constructor to the phone. They have a crazy format, you don't want to use custom attributes and what not every us much.

D

Greater than folding it doesn't really have a constructor, we got an issue. Does tender.

B

Voice audio to do custom. Actually it's not. This seemed similar to custom attribute that.

A

Database admitted a deformity of object tag. It's.

C

Really, what is its the pension? Just click on each.

B

Other I mean it seems fine way.

C

Of looking again, we can better.

A

C

A

C

B

You're asking right no.

A

I think your enters to the computer.

B

But that's based on my intuition so very.

C

It would be good to let me actually live up here.

A

B

And I see so it's got some.

C

Okay, plop a blah blah blah blah.

A

State machine noises or isn't.

B

Reserved their back to its that have specific blog formats, then.

A

I can't stand any guilt, very old people named pain, but.

B

It's so it's extensible right because you basically say all take a if I. If you find us to it, then the blob looks like this incense.

A

That's actually not bad well,.

B

It certainly helps it means that I don't know.

A

Yep make sense: sweet I was a time with the name. Okay, I mean the only.

C

A

One could consider is removing the word custom of it. Well,.

B

I think it's actually kind of nice because there's a lot. There is some similarity because I'm attributable to look I guess.

A

Everyone said like, but.

B

They they're different, so.

A

That make sense.

A

Right then, y of that um talk about document.

A

The header, I suppose, is just giving us.

A

Since then, the entry point of the year is.

C

It and appointing.

A

D

C

A

Ahead, uh probably not a good work to do here, it's not in the spec okay. What can accept you here?

A

Well, I, suppose it isn't it in gently. Don't you have everything you would expect an API that given them and that's it so.

C

A

You can get the debugging.

B

A

B

Metadata I, don't know just an interesting normally, the metadata does not have enter point. Oh there's a Thursday.

B

Elsewhere, like reporting the P file before you locate them the airport, because every point token or or r-va that get out sides I imagine this is just intuition based on the name, then, when he bugging scenarios and if you have only how to BB, still need to get this information, so you need to store it. Someone.

C

But was the Padres.

B

A

Interconnected the condition handle yeah.

D

And why does the PDB care about that record in this case the front against a where they would call entry point to.

B

B

Can ask for offline? It is a little odd to me that, like this yeah I, better struck with one he'll get one piece of information. I'll.

A

See what kind of trick did this that wasn't.

D

Even struck whether there was a civil class too hey, it's a little unite to it, because.

B

We do that for the other headers cuz. They only have one header you're right play it one header and then he thought, like some of them are getting large. So like this truck thing was getting like. You start passing around like deciding.

D

On to find out more information, yeah I do.

A

To me, though, Jonny.

A

D

Suspect we'll need to rename that property24 method, Valley Stream massive body, of course, yeah.

A

I didn't put it everywhere because it always had to rename like 16 things, I.

C

Don't know I would be dangerous for weekly change. Only change is not.

B

The matter body and it's not the method bodies like that name.

C

Is wrong? You want to make a distinction. You.

B

C

B

Not the body the body is elsewhere. This is things like put. You go with the body to tell you about how to debug, but it's none. It's not the bond. Okay,.

A

Out of curiousity, why wouldn't we just make it the one thing that has both.

B

There's some similar to the thing that I was saying at your point. This is my based on intuition. What method bodies are not in meditate there elsewhere, then the method just has a r-va. That basically says you know my.

C

Method, my aisle is.

B

Like so I give.

C

You only reading metadata.

B

You can actually have medley and I'm.

C

Method bodies, we have extension.

B

Methods that let you go back to the P reader and say you know, give me the method body, like the actual il for the actual good point. You have to go back to the period because if you only a.

C

Metadata readers.

B

Capable of reading just a metadata block, but there are no bodies in the meditative.

A

Law, I thought. The point is, you have been exposed yet, ah but it's just a different type. I guess that makes you on a different type. I.

B

Guess I'm exist.

A

Yeah well yeah, there might neck I'm just.

C

Taking up what happens, if you open the reference assembly through just metal vapor will enjoy bleep, do I, guess you're.

D

A

C

There were there'll be bodies, mission accom, they were my intuition. Tell me just compile. Is it away actually can tell from ethylene sure.

B

If they saw I want to meet with reference to yes, there's a flying usually marked in some look like suicide terrorism fly, but at the end of the day, if you just open like if you chose up in the metadata section, you can get this pointer to the method body. But then, if all.

C

You have is that it is actually have nowhere to go and like they now.

B

Give me the method body is like well, you have to having people over that top. The other section.

A

Then the moment.

C

It's pretty like obvious, like it's not like.

A

C

Not narrow continue anything yeah.

A

It all looks what I would expect it to look like.

D

You're going to get a custom collection to get like get custom. Debug info, that's returned to collection. I.

C

B

I see it probably needs an ass or something because we have get custom attributes right next to it. So it's the same pattern right. You can get just like you're, given a handle to a custom image you, as associate of the net you get like getting getting handled directly to the little blob. Basically well, the record that says there is a blog, you get one, but then you.

C

Can also say, gig air on this entity.

B

Going the other direct just give me all the custom thingies that are attached to it. I guess I should have enhanced I guess it should be.

C

Losing a parent same weird, but we're gonna get custom, debug approach, but.

A

I've, wouldn't be arable from you.

C

Without okay, Lisa's is.

A

Getting infos better than informations.

C

B

Okay, if you guys are here, I, think.

C

It goes it's fine, informations.

A

Will be very hard.

B

I guess we can also call it custom.

B

A

B

That is why we can always call it is you have to call it now if you just use the handle I in custom, debug info handles absorb, because we don't do that everywhere else. Doing that for here, yeah we're worried that because I would have put handles getting enough handling. Will.

C

A

Custom debug log I, don't.

B

Know I think it's fine if you I think it was acknowledging.

A

B

A

Mental to win even.

C

In the plural form,.

D

Give must bodies, that's the first read so much enjoy.

A

Holds water here he is the floor. Thong good! Let's go.

A

That seems fine, you pinch point a blog reader all over those things, but it's true can't make sense.

D

And others look, look it here. God.

A

Either clean is consistent. Alright, I started.

C

A

C

It's just jump through it.

C

Yep yep yep a loser. Oh yes, sorry.

D

We take time you said the actual information we using daytime also little bit. That's.

B

The constants and we have a tee time officer angles- were just missing.

B

If you look at concept that code, they probably already have those type codes, but you just never had a need to must see added you.

B

Can you look at constant that coat.

B

C

B

Those are so that is interesting, night ice, there's no Constantine time trial.

D

B

Might have the special occasion hasn't gotten be done with this is what else I thought. This was just missing things that this spec talked about. Reading my review this.

D

I would add it up to the visionary date, the information I think they should be here in the console. Well, no, you.

B

Know I wouldn't do that because the constant this is existing concept.

B

Like I, don't know, I mean she would cost entry constant can never return date. We already have a positive guessing, it's just a provocation. Obviously no it's not reads anything. You can read up I, just I made it next week. That was on all right.

A

Right I talked about that custom view an inflammation handle. These are just got meeting place for a big promotion. I.

C

Think my hartals I don't seems right. What's that it.

A

Was just a second thickening would what would what we're saying is just copy and paste boilerplate right? It's like equals, costing operators to mirror class hierarchy that you can't do abstract and that's pretty much. It.

A

This is my writing performing code. Internet kinda stuck there's a little that is kind of based on personal.

B

To handle so we didn't have an any handle. Originally you just I've handle and then all the kinds of hangings just basically.

C

Handles just so, you can you and.

B

Ask you what kind it is and think you can cast it down to the other handles, but then it turned out that some of the handles that needed so I thought like this is very much invitations etail, where you have 32 bits reserved for a handle and basically which follows like a metadata token. But we had some things which, like a string which is in a separate.

C

D

Tables in string need.

B

And the offsets there can be larger than the 24 bits of the we.

C

B

Handle now is actually as a 40-bit struck, so so we can represent any kind of handle. First entity handle can only can represent anything, that's in a table, and so it's Kim ends up being much faster to use entity handle. But if you really need to say a string or a or a table record that you just had on, you need to carry that extra bit. That extra buddy.

A

B

Did you handle is basically.

A

Between handle and everything else is done to it to finger Lynette like.

B

Hamill and.

A

B

Handle entity hobble method, definition actually.

C

Play yeah if these were, if these were objects,.

B

Yes or the implementation.

D

Are they actually storing a few of affinity handle these cases well.

B

D

Like they all lot like.

B

A feel typing interface.

C

B

You're like no, we don't ask the stores in some cases we could. But it's all it's all implementation detail yeah, but it turns out that you get better cochin by not doing some cases were evenly. But that's that's. That's trivia and.

C

D

Matter what was trivia yeah right.

A

Next, all right, so we talk about debug header already.

A

Here's our document mmm can handle same boilerplate, intellectually same boiler. Plant named blob, handle.

A

C

A

Cons kind of makes sense import definition.

C

You think we have time for recording, for definition,.

A

Really? Yes, it's a different basis. What is the same thing yeah? What a language wee-wee? Oh.

B

A

B

Don't think culture is closing on laughing I, don't think it is just run it out of me.

B

We also decided, when I review this way back, that handles what.

D

Is that, actually, what is it important mission discovers? It.

B

Looks like it's telling you what source, what you mean spaces are just from for.

C

C

Just not anything.

A

Yeah things like give me things, probably.

C

A

In C sharp as well, but this year fish are net vb sure. Well, it's on you with one incisor. Oh, you know what I think, that's for when you're in the debugger and you're riding in the watch window, that the debugger knows which usings you have essentially for the given.

C

Source file, your intentions.

A

Go yeah derrickson.

C

Also, the debugger now debug give a military documents if what's go, anyways yeah the other.

A

C

D

A

Yeah more of these so.

B

We got in your case. That's a new feature, not related. That's super awesome, so.

C

This thing just compares.

B

The bites of from a handle that represents the name of something represents a string in some way here are slightly orthogonal that we.

D

Just need it for debugging purposes, avoid.

B

We had the to do you want and just never got around to.

C

A

Compiler was allocating 14.

B

Db cases like that says, is just.

A

Me, or is it just, I think, like generally speaking, bulls are shitty and AP is because the problem is you, we didn't, you say: equals love, habla, como, tu, como habla, like what the tis true or false me in there. It's.

C

A bit dicey because, like I did think about this polite.

B

But you really can only implement two kinds of string comparison there like if you want to do anything like so.

D

I don't want to even you create another string.

B

Comparison, you know, because it can't be all right.

D

Gaby, though, can't.

B

Be string comparison like I'm going to implement. You know.

A

Quality know and would ok another gimmick so like.

B

It's really pooling, so you create a sort of competing with string comparison and let.

D

Me just rename them x equals more patient. Could do that, but.

C

What is it be very, but.

D

C

Is not helpful. It's okay to ordinal, always.

A

B

We're not going to like, because we don't have we number, don't we don't materialize, 2 strings a certain comparing bites from the string that you want to convert you to the metadata and, like we don't immune the business of culturally like if you want to do culturally, like get the string out of the metadata it'll, because you typically tipsy season will talk to globalization of a string like we're. Not enough distance like on the.

C

Other hand like.

B

D

Do have the request additional general strain relations in front of put them into method names like a cordon yeah.

A

So then, that's what I'm thinking I mean there's multiple ways to do it by one of.

B

You is like you end up, will say: you're writing something, and you want to like give you be in our case or something else don't now.

A

You have to like your noggin.

B

If you're not really like, you can imagine it like flowing down like, but if you can things like well.

C

B

Long time, no then like by the time you get down, just like sure you can I personally found like that's a trade-off when you start ignoring things like when they're shortcuts. But there's also like an overload that lets you that overloads useful one is like a helper that feeds it so like hey having only de method, neva, not sure, if that's better, but um the.

A

Method: name is a shitty for data-driven. That's right, I, I,.

B

D

A

D

We have the pattern, is about I, don't think it's necessary room right, there's a lot of look.

B

Like that, a writer I mean.

A

Equals I mean boolean, you would kind of think it is case, sensitivity and I. Think for.

B

Steroids a liver know, if you don't know the directionality like you do because of the existing could be I in the framework they're all like this true well.

A

Yeah I mean if you c equals.

B

The Rings I would never call this without saying your case colon, yes,.

D

Upstairs dead too man.

B

Unless I was possible on over.

A

And as you have tools that are smart to tell you that this is superfluous, you can remove that some competing product is all the time.

B

A

That one is a bit I saw that earlier, like it seems it weird I've, no idea what that means was probably like.

B

Four, when they remember when they do a sink or whatever damage some stuff and I magically, he budget so vain you tonight. What.

C

Should I should is, it should be baked into poor excuse? They.

B

Have to get the information tomorrow right and it's! This is informational at the.

C

End of the day, this is you.

B

Know the information that needs implement the debugger features does seem the whole specific, but I, but I don't know what else you do it.

A

Because I know.

C

What's between friends and you Peter, like they say, I'm.

B

Assuming I'll be nice, if you could.

C

Use existing methylate, oh you did. We do so reverse me, I. You have to look at what that I am forgetting. We beat alarms when.

A

By the names by the paintings on intuitive it probably something also.

A

Supporting a couple of those.

A

Sequence, porn.

C

C

A

Should they hidden I'm me visible.

C

A

This constantly visible, it says if it is filled, no I meant another property.

C

Such as you see me something I know it should.

B

A

This one already exposes a bull right, which I suppose just does the check whether the start line is they didn't I I, don't know the.

B

Question I think this: the field should be.

C

C

Me or kid that no.

A

C

D

There won't be don't like to yeah. We went through this in a very short view. Their time.

C

Like this and change them all the properties, is it okay,.

C

The secrets point.

D

Is I inuman Walt really cradles? I.

D

Should add blog reader, it doesn't look. A lot like a memorable should be part of this invested into that she was points up our work.

C

Little weird china, numerator grand national, pretty weird.

D

A

What what anytime, I'm.

D

Wondering whether it just where do you get the white Walker for this? Is it tied back to one of the other pieces of her like it's a time back to sequence, point should.

C

D

The numerator kind of thing on simply visit one sequence, point collection, all.

B

The rest of them and disc is.

D

B

D

Have a numerator just sitting in the injuries that usually tied back to something that you want to know right. In this case it looks like it's plain white buffer.

C

One more low in the format.

B

Of the sequence points right see how blood that the sequence points, then you want to.

D

Get reserves? Oh holy sorry, blogger,.

B

But I think it just returned the reader, but that means they won't be able to it.

B

C

A reckon- maybe obviously this.

B

Point collection and then returns ya. Consider I got.

B

I, it's a little weird, oh well! It's good information.

A

Because Hector is method reserved.

B

Yes, these are the methods that, let you we are the raw. If you know from some other.

C

B

The numeric value, like you, have a metadata joking you're going, can.

C

A

B

A

In the mix ins custody, very information.

C

A

C

Yep so yeah, that's it.

A

Yep more, you love the comments. I know, I didn't see any major, nothing.

D

A

I think the only thing that we talked about in the beginning was whether.

C

It's refer to split it out or not, and.

A

Never concluded it not yeah.

D

It looks like it uses.

A

D

The same instruction for handles and tables up like that yeah, the main thing I.

C

Will just do like with some super generic trains and the problem is dat ice like we don't want majority of our customers to ever see them or use them right like they're? Not very you know it has to be come on the use, so the problem of generic names is then they show up in searches where you say msdn, you know document you probably don't want to say. Yes, whoever so yeah.

A

But you also saw that we already these things, have super long names, because they're combined all the time. My like, if you see, if you pick a concept, you always.

C

A

A handle collection, you have handily of a definition you're like, and so, if you already pick a very specific name, the names get completely.

C

Unreal this all you know like, like you know, in like phrases, you can help skip the qualifier. So let's say the document was renamed to source.

D

C

B

If I even still have the something can solve a document handle which returns us a source document or something I.

A

B

A

C

Think document.

B

Is 5 out of work? Do I think um nothing.

A

Document is certainly one, then it's a bit too generic I, don't think I mean more bouncing home, doesn't just.

D

Go about this year's big things going to do. It looks better right.

A

um What else do we had? No, is it no.

A

Questions either.

C

A

C

Time I check for.

A

The record I did check for questions.

A

A

A

It seems I, they were some things that were in the Fallen it weren't in this backhoe at the laddie buck header, for example, with the entry point, any search.

B

For a trick way.

A

I'm doing a search for entry point.

B

There's the street there is the same value stored in the seal, our header in computing file. This is the problems that you only have metadata.

B

You don't have it features a PDB file or you don't have a key from look I figure out, which method is mean or can't you stover they'd.

D

Have to be in the same thing here: they're, never intend to same values, you don't you're. Given him overload, the two I mean like we have an entry point exposed somewhere else.

B

You can because the metadata reader doesn't know we haven't exposed from the skill I headed, but the still I had heard something of a metadata. It was nothing like it like.

C

The class metadata reader.

B

There's no like it just.

D

Takes a metadata.

B

Slob right so there's a more general.

D

Purpose to debug, then, is it another way of exposing that your point from the better view.

C

B

It's not really, I mean you can imagine not really like yes, I guess you can imagine a meeting one thing that only has the header and then has no no, that tables comin.

D

Just adding and I god.

B

I was just making a binge.

D

Opposed to be the same on one or more than I, even without the peewee, you can still get the entry point expose it.

B

As entry point out and budgetary readers, you can explore them under their ears metadata reader doesn't doesn't it take some metadata section? Flashy, yes, doesn't know, it doesn't know how to get a drink, but now you could get the debug one. If you have debug information, which will be the same, it's.

C

A little weird, it's a little.

B

Weird but I mean again.

C

B

C

B

Birthdays, what about I.

D

Show like to know what to be buggered each I.

D

Mean I think you could imagine.

B

And I not to talk to my site burning, some of it. It can seems more like more custom thing, f8.

C

Hit the break point.

D

Judging the break one of the what the initial I mean.

C

You can basically, if.

A

You feed at the way up full of whether it was fef a door if you'd ever know one of them yeah, then the base you said to break on the very first instruction like how do you know? How do you put it over that? It's that's.

B

Right or not, I looked a little weird because it just had the one things that keep on your header, but I can guess. The idea is that you can add more things, although I don't see too much importance for this getting larger, like there's no Field here that does yeah.

A

I can all to see this just being a person right, because you don't have lines or anything yeah.

B

Add more fields, weird of the one debug struck with the one entry point in it.

C

B

A

Then case, maybe we just get rid of the type and just make it a message right. Imagine reader that says, give me the entry point, I guess yeah and then give you that day, because I mean what boy is you say like. Why would I need to type then just set the single entry at the forum and it's odd, isn't even extensible, but.

B

D

A

D

Other dogs for putting stuff in the header, yeah.

A

D

Suppose these other table corners things, but.

B

We're going to ship this so, like you have to I boo boo, you would have to put some serve fly there to know that thing.

A

To know that, there's some data that, where you going to put it and we'll talk to muffling yeah, sounds good, was a thing called again. Was the u-boat.

D

C

Debug header, you know minute.

A

Eight ahead.

C

B

Is mirroring and I think we already did this person.

B

It is gonna, get.

B

B

Just we call get debug at your point, but it generally speaking it will get. You get your point. If you have a DVD of people, yeah who's, that the interesting thing will appear, even if you get injured from there, it's not giving you a method. Definition in blind, it's good! You giving you it's a walk, monitor all you get so convert them yeah.

B

But me you can get him a you get a token from the pier ear and then you can convert that to a method efficient and what's a bit of all right, um I mean you didn't really you get out.

B

Maybe we just say get edgy point you get up and in the extension EP on as you get a beating, it's not your typical. It takes an ereader and then it tries to find it either the debug editor or the important like you, the P readers optionally null or something it's weird man. It's gonna, get weird I think this is more in the spirit up before manages that we don't do like this is literally like Krista hold on how this month, there's like it's something for for the format.

B

So I don't know that we want to detect API okay.

A

B

But uh I think I have two questions. If that header is meant to grow, it doesn't look like it has an affordance for it and it's not meant to grow. Then she just have one method.

A

That seems very reasonable, actually.

C

A

Yeah just close my notes: now, I'm opening up who you.

C

Can prove music.

A

That's not going to end well, um alright, what you're hot.

A

That the baby doesn't.

D

Live here, those right.

D

Actually, the thing with a stream yeah I.

B

If, if crystal wants it.

A

Why do we want to call it a day yep? All right, then I'll. Stop the recording thanks, guys.

C
