A

Unfortunately, today our product owner can't attend the meeting, but we so I started the recording and we would be able to as usual, we would be able to provide the recording on a YouTube and we will send mark the recording of today's video. So today, our our weekly meeting is not it's not regular one, but because we will coordinate at the end of the contribution day, which happened just before the mage con conference.

A

Today, more than 85 developers visited magenta chief office and took part in the magenta contribution day and as a result, we have pretty interesting contribution, pretty interesting ideas, especially especially devoted to devoted to multi-sourcing mentoring. So we have several updates for you to be shown today, one of the update, so you can see Japan and other people who are awaiting to make a presentation.

A

So one of the one of the one of the big update for us, which we want to share with you today, is that finally, we managed to package and build the release candidate version of MSI, so the release candidate version of MSI. Let me share my screen.

A

We managed to deliver final pull request which, which contains several bug fixes which we, which we've done during this week, and so there are five bug fixes in the scope of this pull request and we managed to deliver this pull request yesterday night and actually that was the last pull request which finalized MSI development for to the tree that Oh and after that today. Today morning we built the they released candidate package, which already published on a repo magenta dot, Cole and and it will get to the release candidate of magenta tulips read at all.

A

So this is a pretty big big news for us and big news for everybody and.

A

And probably, let's go to the presentation of the pool request created in the scope of today's contribution day and the first one gonna be padding so but income and share what he did.

A

A

A

So hi guys, sorry for the short interruption yeah I had to figure out which, which covers the the right connector for the port for the ammonia.

A

So today, I start today with the idea to make some maintainer stuff, but after reviewing soundpool requests, I figure out that there is always the same arrow on Travis and after searching for some issues have already found out that there are already a issue created by eager for for this buck. So I start to investigate, and here it's still in progress.

A

What? Yes? Okay guys? Can you hear me? Yes,.

A

Okay, so, and so what I figure out so far is that this buck is regarding saving of stock items and depends on the reading dictation products behind. But investigation is still in progress, but since it was pretty hard to investigate, because I need to run the test several times and it took time I doing at the same time, another issue it's about reading files and all the MSI projects. So all the modules has really files, but there are pretty empty for now.

A

So right, the pull request where I try to describe what is the responsibility of each module and I specially focused on on the point. What is the extension? Where are the right extension points for this module if there are any, and especially about regarding our single responsibility principle, which is in the modules, which explains why we have so much modules? And what is what is the principle behind it?

A

So probably this is also a pull request where Lori could be involved, because it's a lot about text and I also try to link with deaf talks to the right pages there. So we already have here a few pages which are describing what is msi at all, and especially the topic I appoint before our single responsibility principle here also described there, so I linked to this page, but take a look in this lorry. Give me feedback, and so that's it from my side.

A

B

A

So the next present are gonna be Ricardo. A que xeric will show you big functionality, which was implemented during these actually.

C

Well, it started implementation.

A

Of this functionality using the magenta live Bureau, yes, and he managed to finance I D, so the presentation of new source selection algorithm. So, as you know, in a to the tree that over least.

A

Distance-Based ovaries and moreover, he implemented not just implementation, which is based on the Google Maps API they're offline fall back, so I will stop even the stage of recorder and I mute myself. So Ricardo will tell you more about that.

A

We can't really hear you Ricardo.

D

B

Can you speak up I, don't know if that's just my problem. Okay, it's very quiet. We don't hear you.

A

Excuse me: we had some slight technical issues, so Ricardo already started his presentation, but he actually was disconnected from zoom. So we will reconnect to Ricardo now and keep the presentation going absolutely can't miss the Rick.

A

A

D

D

Okay, can you hear me now.

D

Please let me know if you hear me: yes,.

B

D

Laurie's saying yes, so I'm sorry I just started my presentation without soon, but now I will try to explain you again. So basically, let me share my screen test of one, so what I did is to implement distance based selection algorithm because, as you as you know, and as Igor was saying before, we had only one priority, best selection, algorithm, I'm, not sure yeah I am.

D

Do you see my screen? Okay great. So previously we just had one single way to select the source by source priority. Now we have with even distance priority. What I did is not only to implement one distance priority system, but even a kind of distant provider. So you can choose between multiple providers, because maybe you can want the distance to be calculated by Google or maybe the distance between two points and your configuration.

D

In fact, you have the possibility to switch between google map and one offline distance calculation that is based on one database that is retrieved online and in which you have postcodes and latitude and longitude.

D

So, of course, this is less accurate google map, but of course you don't have to pay a google map, and if you use the Google distance provider, you can even choose between different computational modes, so drive in working a bicycling well, actually I decided to add working and bicycling, for example, for people that may run delivery by bike or something like that. That can be actually interesting and you can switch between distance and time to destination.

D

So basically, this is what, and if you spit in action, is nothing special when you see actually yeah and actually because you select distance priority and you got them sorted by distance. So in my specification is my specific case: I have custom source one a custom source to do two and they are both in Italy and the shipping address in Italy. But if, for example, I change, the custom source, one and I put let's say in Ukraine.

D

Ukraine I hope abroad keep in the right way.

D

Do you have any valid postcode for kill.

D

All six eight, oh, there is also another cool stuff. If you leave latitude and longitude empty, when you say with automatically computes computed using Google API and if I run the suit selection based on distance again, if it works, custom source two should be the first one, because it's in Italy and custom source, one is in Ukraine, so is much more expensive and that's it.

D

A

Thank you Ricardo. This looks really amazing how easily you implement it.

A

Such a big piece of functionality and I'm I'm, really little bit disappointed that we don't have a room to pull this personality into to the suite at all anymore, but I believe that will appear in the upcoming patch update and the next one are going to be sip on to show you another pull request created today and the functionality UI improvement introduced for a messiah, which would be especially especially useful for big merchant, who has big big merchants, who have quite a lot of sources.

A

So, while the pond is managing to connect his laptop to the two HDMI.

E

E

Okay, so everyone.

F

Let me share my screen with.

E

A small screen: oh yes,.

F

He looks good, we.

F

Stopped short and start from scratch.

E

Still not here, okay, I'll, move everything. Another screen.

F

Looks good and.

E

This technical problems.

E

Ii need additional time to handle my screen.

E

Yeah, like you, okay, can.

F

You see yep, okay,.

B

E

Started from scratch.

A

So while we have like technical issues, I will just tell a little bit what actually step on what to demonstrate so, some time ago, on it.

A

Don't stop greet and he added assigned sources a column and in this column he he added Frederick.

C

A

Sources assigned to particular stock, but depending on the stock for big merchants, who has a lot of warehouses, this list can be pretty big one, and this will introduce some.

A

This will probably spoil the the usability and and the look in the and actually looking few wouldn't be so good. So the idea was to add a tool tip which will provide an ability to.

A

To move the matter.

E

E

Yeah one two one, two, okay, so equate it to request. That makes our to grease much prettier. First of all, it's stop great end product goods. This to request its is divided by different branches, so well be able to show just one, but believe me, it's it's almost similar, so any provides us ability just to show the what was before that.

E

As you can see, this list is pretty big for the one row and my credit in you knew you a company which will use tooltip for showing the for cutting the this list and making it it much that and all another sources you can see in a tooltip once you hover to this code, so it looks like that is the product way so and was like that. So and the same will be here, but the another branch so I think then that's it from my side.

F

A

A

Thank You Stefan I seen that Lars also made one of the pool requests and he participated remotely so I want to ask class whether you want to make a presentation of the pool request. You've done today.

G

Yes, it's a very small proquest. It was some performance optimization, but I can show, of course, feel free to share your screen.

A

All the contribution counted so don't hesitate to.

G

Think you should see my screen not.

A

Good, give me a second.

G

Yep I see good, so what I do today um in most cases, I starting with refactoring for Enterprise Edition and make a compatibility to MSI and then I see some performance issues at a code, because I have some checker in my pitch piston and they told me hey Lars.

G

They are some optimization and this was the reason why I open the Perot trust for for introduced absolutely far paths to current methods, because in science, PHP version 7.0, it's some AC optimization for that, and if you have many calls it increased performance, our it's a small performance increase meant, but if you have a lot of course, it counts.

G

Also I see. Ok in we have many for each of every merge, but our merge is not required to have this and for each pickers era, merge is very slow in for each also. It needs a lot of memory. It depends or is why yeah, why I change to the explode and return the error emerge as last?

G

This was my to optimization yeah. This is from my side.

A

Okay, thank you Lars. So, regarding the Reynard, probably, this is pretty valid concern, but regarding the eddying aliens flash and the count in that global that all that function should be taken from the global namespace I. Don't think that this is the practice practice we need to follow in.

A

In a typical code development we usually do on a regular basis when we call that PHP function. So it's I wouldn't say that this is. This is really good practice we need to adopt, but, but regarding the merge said that if this is pretty very valid concern, we have it. We have it in a forage and the North, it's a it's pretty early source, so the function which which need quite a lot of resources for the processing so yeah. It makes sense.

G

Okay, I will change this pull request to only reemerge. There are the example. What is the resource- and here are a lot of performance measurements for airing March and also the same is here for function, f, q and replace. There are also some benchmarks yeah. They.

A

G

Lot of course, but.

A

Yeah I, but currently, especially for Web API, we need F p.m.

A

one of the requests created by record day is not yet mer, so we are not able to use not fully qualified name spaces or web services, especially it's pretty important to have the fully qualified name space in a in annotation okay. So, let's, let's proceed further and okay. Okay I will change it. No problem and the next one, probably gonna, be Laurie. Who will provide you an update of our documentation at what and water was prepared for the upcoming release.

C

You're ready, let's start sharing I, think everybody can see. Yes,.

C

Alright, everyone so everyone that pretty much knows this as the user guide, we've kept it in the wiki for MSI and it's been really good. I've been keeping this up to date, based on any PRS coming through keeping it in line with develop, but now that we have released formally I have gone ahead and moved this into the actual Magento user guide. So now, you're gonna find MSI through the Magento commerce, the b2b and the open-source user guides. When you click this link, it will take you into here, and here is your new landing page.

C

Now the contents working up a little differently, you're not going to see the word MSI immediately, because MSI is replacing all inventory management. So previously we had maybe two topics. Now we have close to sixty that are pretty much documenting everything you guys have done. It's broken up to help merchants understand what is in the new MSI inventory management how to get started. You know how to configure and just get going everything all the way down to managing their orders and shipments.

C

You o add a link, so everyone can start looking through this over on this side, you'll see how much content has just been added in this one area, and when you come up through here, you'll see you have this entire section. Quite a bit. Also other pages have been updated to show MSI content like each of the products.

C

When you go to update these you'll start seeing some MSI content on how to add sources, add quantities all sprinkled throughout here in the documentation, and we also have a page where we are tracking all of the new image into extensions, and that's where we'll have some call-outs I'm going to see?

C

If we can add some more names here, instead of just a link, you can see the Rick's previous work as well as everything you guys have done here, which also has links to all of the dev Doc's from within the User Content, just in case they're interested. But this page here will continue to get updated. As the user guide, that's in the wiki is going to continue being updated, based on work that you are actively pushing in to develop. I intend to keep this up to date with develop it that way. Every milestone has documentation.

C

This content in the actual live user guide is only going to match what we push out for two three beta and then two three GA. So it's also fully searchable and has lots of really nice diagrams and information that is going to look pretty similar to what you've seen before. That's pretty much it. Unless anyone has questions now add links to slack.

A

Thank You Rory, that's that's really great job and the please sure share the link to the documentation to our select channel I believe that lot of people will will need to look through this documentation and because many people ask about the documentation, even during the today's event, so I believe it will be really helpful and, and one more thing I wanted to share with you.

A

Let me share my screen one more time. I just want to to provide you a little bit more about one of the, but we were struggling with for a half of this week and one of the contributors was currently on a call. But who is he? You know this guy, this forgive from from charity, but he's try a little bit two men to make the update by here by himself, but he helped us.

A

He helped us a lot with fixing this issue so I will just I will just provide you already a little bit more details about this issue, because this was the last Booker issue for us, which prevented us to make the LC release a day or two days earlier. So the the main idea- and actually that was a gap in the initial implementation that we did not.

A

We did not support the custom option because a custom option in a product slightly changed the s cube of the product and, as you know, in MSI we work all the business logic is based on the nature of identity, so on the SQ, but not on the product ID, and we do the source deduction. We do reservation creation and the compensation or reservation creation based on the FQ only and for us the products with the.

A

So for us it was a pretty problematic because our algorithm can't find that appropriate Pro using using the SQ all of the product is a custom option. That's why they're coca stock stock deduction calculation was made incorrectly for for customer for product is a custom option and the initial fix was to provide the fallback to the product ID, which is also stored in the order item. So, as you know, in order item, we have two fields: product ID and product sq, and that was initial fix provided by Sergey.

A

But eventually it appeared that configurable products storage. So that the Product ID in a product in an order item for the configurable product actually referent to the to the parent product to the composite product, but not to the variation and the regarding the configurable product, we're supposed to work with with the SQ so introducing initial fix for the other products with a custom option we actually introduced the but for the configurable product. So Sergei introduced a dedicated service which has a several fall backs and so initially checks.

A

Whether the product is a managed, so whether it's simple or rich, all downloadable, so whether it's the one which support the source management manipulation. And if so, we we proceed with the visit, Product, ID fallback and if not where we are taking just the SQ, because in this case it probably is a configurable product. And in this case we take the SQ. So this is probably maybe not an optimal solution, because the optimal solution would be to refactor.

A

They exist in the existing way, however, how it stores the data to the order item, but they can into account that we are not allowed to introduce backwards, incompatible changes and taking into account that we don't want to spread this kind of I wouldn't say that desirable logic into all the MSI codebase.

A

So we just introduce additional service which supposed to provide the correct, is cube based on the order, item and Sergei made that series to be used in every place where we need this conversion from from order item to sq, and this is how we fix our latest bug and after that, we spent almost two days on testing this, because the fix of this bug affected quite a lot of areas of the functionality. So we had to.

A

We had to re test all this all the order, placement and the order shipment for all the composite product types like similar, like configurable, grouped bundle and, of course, simple and virtual, and also we we made quite a lot of testing of the configurable product with the theme of his variation, which use a custom option etcetera. So we made quite a lot of testing and finally fixing the bug we we made the final packaging as as I said from the beginning of today's demo. So thank you very much Sergey and thank you very much.

A

Everybody of you who was was pen time who spent time on a messiah contribution and who made that happen. I mean our release candidate and this probably all for today, sorry force for some technical issues. We had because we in El detour iam, and we are always switching our switching our laptops to make to make a possibility to broadcasts the screen to auditorium, and this probably introduced some some noise- maybe some so maybe it just annoyed you little bit. But- and this is all this is all what we wanted to present today.

A

If there are any other open questions, I'm, not sure that it would be suitable if it, if I'll be on through and right now. So just in just drop your question in a message like channel and we will be glad to answer all the question. So thank you very much guys. Thank you for your time and see you in a week on the next MSI weeks, the demo meeting.
