WG API Expression Bi-Weekly Meeting for 20210105

A

All right uh welcome to vertical api expression, it's the 5th of january 2021. um We have nothing specific on our agenda today. I don't know if anybody wants to bring something up.

A

B

Switch something.

B

We might have something but just move on.

A

All right I'll I'll uh switch to the ga requirements.

A

I see them: okay,.

A

A

A

Clients, I don't think jenny or joe, are here. No, do you know anything you antoine.

B

B

No, I know that there's a camp and the proposal from joe and I need to look at it and I know daniel looked at it and commented, and so I need to look at that.

A

All right, um high bench fields, I think uh uh 942- is working on the cap.

B

Yes, I mean that's that's exciting, because it's moving very well.

A

Yeah is the cap here or the out or.

C

A

C

I'll update that.

A

Cool and I'll locate it later exciting.

A

That is yeah. I think we, we should be really good on that. um I don't know if we have anything uh still open, we need to take care of there.

A

um I think this just the one point I mentioned with making it easier for people to know if applies even available is is more for the clients and not for this one. So you should be good.

A

um Julian is on this.

B

A

um The others might know if it's me or you uh can, can you just understand me or should I be wait? Can I turn my volume.

D

A

D

Think I don't have any problem hearing you. Okay,.

A

But anton you're also a bit bit stuttery for me. So maybe it's a connection.

C

Yeah, I can't hear you.

C

A

A

um Yeah, uh the dangling fields is still only an issue. I.

A

A

The web version is particularly weird because I can hear I think I'm done typing, but he's muted.

E

A

D

Everybody's, like.

A

D

A

Okay, okay, I think I can hear you better. Does it work for you.

B

Yes, it's better.

A

B

Okay, you move it's, it's clearly more complicated than I expected, so I need to think a lot. I need to go through the code that uh prunes the the field and kevin I think looked at it. So it's terribly complicated.

A

B

It's pretty confusing to.

B

Spend some time.

A

Yeah, it's it's! uh It's uh not not really intuitive how it happens. I remember that.

A

Okay, um quantity fails type checking.

D

Yeah that one is for me, I uh started looking into the issue and antoine explained it for me I didn't start the code, yet I will work on that this week.

B

Okay cool, am I ready? No, did you say something like that about uh about this theology like did you say, do you.

D

Think the solution.

B

D

I will um I will first implement a solution that we will. We already talked about uh the easiest one, but uh after you see that and it is merged, we can think about the difficult solution. That is the actual um solution. I I I just thought I didn't like that easy solution, but I talked to uh daniel about that and danielle was happy about having the easy implementation first, so we don't. I think we need to go to that difficult route yet, but in future we might need that yeah.

E

Okay, come thank. You.

A

Cool um directly converts you, the instructional, schema to smd schema.

F

Oh hello, hey, um so I think we're antoine with us already um we have a pr out, for this um probably just needs daniel and stefan to look at it um the title's, a bit misleading. um I think we actually decided not to directly convert the structural schema to smd schema. um Originally, it was around fixing a bug where, when we pass in the uh x into or string annotation um there'd be some issues, but I think we found a way to directly fix that bug without like going through the conversion process.

A

Okay, didn't you didn't we want to do the conversion for something else? I thought I remember something.

B

I don't know for now: it's simple: it looks good, it does the job. I think it's the best solution and I I foresee reasons why this is eventually going to fail, but we don't have to consider them now.

A

I thought I remembered something with open api three and two.

B

A

B

I'm I'm trying to work on a proposal to get rid each of the open api v2, um but I mean this is for the long term. Okay,.

A

And it's uh this won't block us to go. Ga.

F

A

Yeah uh mutating admission controls can break many fields. um I managed to get a test and I think a fix I still have to. um uh We still have to define exactly what the validation is, that we want to make right now it's um api version. This is not allowed to be empty. The fields type is allowed to be empty. As far as I read, because we made an ex exclusion for that um for backwards compatibility.

A

I remember something about that and that the managed fields in general, like the psv1, does not allow it's not allowed to be empty. I don't know what other validation we might want to do. um We have to talk about that um right now. I've had I think. Yesterday I had problems running my test, though, because because of some some local networking issues with not having docker so I'll do what I usually do and I get a vm with docker on it and I run the test again.

A

uh It's it's annoying, but I'll get around it. So this should be. I I yeah I'll, probably get a pr out very very soon.

B

A

A

Nodo is on here, but I think he's working on the sub resource stuff.

B

Yeah, I don't think he's working on that specifically.

A

Yeah, should we remove him for now or.

B

A

I think this was a was a needs help before, because we still don't know what to do about it.

B

It's yeah, I think it's yeah. I don't know about this one. It's not super important.

A

Yeah, we still don't even know if it's blocking us.

E

A

um Expand coverage for atomics I've not seen this one before. I think.

F

Oh, you can click the click into the issue. If you want.

A

um Yeah, I think you won't see that I clicked it.

F

F

Okay, um basically, I split this into two parts. um One part is the open api generation where we need to generate the right opening api spec when we have these compositions of atomics, and the second part is the actual like for structure merge just to actually handle this part. um I have most of the stuff working for the first or generating open api spec. There are still some cases, I'm not sure how smd would handle. So I probably need to consult one of you further on this.

F

But ideally I'd like to probably get this finished by our next meeting. Awesome.

A

Okay, let's switch.

A

A

uh Yeah status, wiping I don't know if jenny had time to locate it yet.

A

It might not be.

B

A

Heard somehow about.

B

A

Yeah, we still don't know how important it is.

A

All right now the check marks mean they're done.

E

A

B

All right, maybe we should move them to a defense section. I don't know yeah.

A

No, it's it's! It's fine! I think.

B

Okay, I think I think we're good on that uh z, zaya ziya. I don't know how to pronounce your name. uh Do you wanna, introduce yourself.

E

uh Yeah yeah sure yeah yeah, you probably pronounce it correctly, the uh you already people, that's confident, uh hi everyone, uh I'm ziya. um I have been united into the school for entrance and uh I think uh um to give you some background of what I'm doing, I'm engineering, google and I'm working on uh configure connector uh like a project. um It's basically a director directly to them to help uh customers to uh directly.

E

You know, provision their infrastructures, it's kind of like a terraform, but it's a more uh toward to uh kubernetes class users, um and so uh we have some. uh We we use a lot of. uh We have a lot of our own crds. So most of the work that this group is doing is really interesting to us of, for example, the server apply we already leveraged it in our controllers.

E

So thanks for doing those amazing works and- and uh I think um um I'm trying to contribute um my insight uh from based on you know, the configured nectar uh experience um around the resource reference and also antoine will give me a pretty uh interesting part, a stat project, to about the immutability. um So I will also shoot uh project on my 20 project and uh yeah. I'm looking forward to working with you guys.

A

Awesome welcome.

E

Thank you, you're welcome.

F

A

Great I'm pretty.

F

A

You you'll you'll think up uh internally about the client work joe's doing.

A

If you're yeah.

G

Yeah I just I joined I'm late. um If there's any questions, I missed.

C

G

C

Yeah we didn't know about the client george, you know what the status is.

G

Yeah, let's see so I think the big status is the the uh the cap is out for review. um I got a review from daniel and antoine before break and kevin. Thank you. You got you. I got your review as well. um I need to make sure I get one from david eads and then hopefully we can get that in this provisional. The two outstanding things we need to determine are um how we structure the um go client like apply request itself.

G

um I had proposed um a signature for that that had some open questions and then we also needed to do an experiment that jenny is going to lead to see if the community prefers the uh go, struct based builders or the function based builders, so we've implemented it both ways um for the entry, implementation and jenny's going to try it with coupe builder.

G

um So I hope to get that um kind of re-kicked off here at the beginning of the year, um but we're still we still want to do everything in 121., um so we're going to kind of try and accelerate things and get them in. But that's the current plan.

G

um And thanks again everybody for the cap reviews. If anybody has questions about what I just down um brought up, I think the cap has explained that pretty well at this point um and feel free to dive in there and ask questions or do whatever needs to be done.

A

Yeah, I think I mostly did typos I read through it, but I'm I'm pretty happy with both approaches. I think my my preference would be the function. One okay, but I mean yeah.

G

I initially really liked the functions and I've um I'm now. I am now very much on the fence. um uh There were some people in the coop builder community that were very strongly in the ghost trucks camp. um So I was hoping I'm very hopeful that um doing an experiment with the community and getting direct feedback will help us guide. That decision, um but yeah, I know also um lava lamp.

G

um Daniel smith was very much in the function camp as well, um so um that I I do expect this to be by far the most contentious part of the design. The good news is, I have implementations of both in tree, so it's really just a matter of getting agreement.

A

Yeah, cool cool thanks again, I I just checked- and we actually have dates in here- are they? Are they fixed? Do.

F

We know that um they're, not I well. I follow up with the release um team last week on this. I think these should be like I think, they're finalizing this week, but most likely these will be the dates um giving their current estimates right now. um So that's why I just put them.

E

F

Update them probably next week once we get the actual dates. Oh um one more thing is I'm starting to work on updating the cap for getting service. I apply ga based on sort of what we have in the document so far, I'm just mostly compiling everything. um If you, if we make any like big changes um to the document, you can just let me know um so. I can.

A

F

Cap accordingly,.

A

Yeah, I think the only thing I want to add is is to mention that um uh when, when the admission controller breaks management, I will reset them, but I can't do that whenever you're done, I think first, I have to get proof of concept out anyways. Oh sure I thought that was already tracked.

A

Is it not tracked in here already um there was an admission kept pr that never got merged. I think, or did it about tracking the managed feeds, and I think we abandoned it, because we had the performance issues and.

F

Okay, okay, but it's something potentially want to happen for ga. Then.

A

I I think we should at least mention it that we do that and give people the opportunity to give feedback, because yeah.

F

Got it? Okay, thanks.

A

Cool anybody have anything else.

A

Silence means probably no.

E

A

Okay, then we we end early. uh I think um all right then uh see you in slack have a good start in the year. Happy.

F

A

Stop recording.

D

Thanksgiving. Thank you.
