thus not intergated inside Lagom
would that be possible?
Elijah Rippeth
@erip
I don't think so since it requires changes to the lagom internals.
Though very minimally
I suspect if those changes were made separately it might be possible.
Renato Cavalcanti
@octonato
Maybe a DRAFT PR, so we can easily compare the source code

@erip

:+1: The required changes are outlined here: https://github.com/lagom/lagom/issues/571#issuecomment-508942154

A large number of changes are just SJS compatibility changes of artifacts. The lagom changes are basically breaking components into separate files and adding a few abstractions.

Will talk to @mliarakos in case he isn't on gitter often. :)
Renato Cavalcanti
@octonato
one thing to take into account is that in the coming months we will be adding bits of Lagom back into Play
and the whole idea is to reduce Lagom’s code base (it should become a thin layer on top of Play)
this goes on the opposite direction because it increases Lagom, adds a new runtime (javascript) and more things to maintain
that’s why I would prefer it to be a side project
Elijah Rippeth
@erip
Understood. Some of the changes could likely be ported upstream, but don't quote me on that
The abstractions might be useful for Lagom even outside of this context (e.g., not relying so heavily on a wsClient from play)

Hi, folks! :wave:
What do you think about lagom/lagom-java.g8#60 ?
Tim Moore
@TimMoore
@ihostage I'll have to leave that up to the core development team. Seems like a fine idea IMHO but I'm not the one who will be maintaining it.
@ignasi35 any thoughts?
Sergey Morgunov

@TimMoore The core team is very busy until :disappointed: But you came to light and I caught you on the common channel. :joy:

Hello,
I'm doing PR lagom/lagom#2251 . I got to the point when I need an outside perspective. Some points are not so obvious. I'd appreciate any response.

Hi, folks! :wave:
@marcospereira @renatocaval Can you find a time to back on our discussion on the forum about release Play SOAP and review my PRs?
Renato Cavalcanti
@octonato
@ihostage, sorry for that. I thought this was already done. I lost track
I will wait for Marcos to come online. It's morning for him

Thank you, Renato :+1:
Just some member of community wait release with support Scala 2.13

@octonato
@ihostage, we are running short in time because right now. We have Play / Lagom major releases that we want to finalize and next week we have company meeting. Can we post pone it to after next week?
Sergey Morgunov
@ihostage
@renatocaval I think — yes :smile:
Moreover, if you do several actions that I described on our discussion on the forum, in the future Play Core Team not need to spend time for release Play SOAP. I can do that myself as maintainer. :wink:

Hey! Please note that Lagom 1.6.0-RC2 is released, with a couple of critical bug fixes: https://github.com/lagom/lagom/releases/tag/1.6.0-RC2

Hi everyone. First of all, kudos to you guys. We are using Lagom at work and it's great. Anyway, we have scenario where we want to publish only some messages to topic using TopicProducer. Current design requires to produce (Message, Offset) pair for message to be published. So in case we filter out messages, it won't commit offset until another message pass through, which results in unnecessary replays when app restarts. I've been playing with API of TopicProducer locally and changing it to accept Source[(Option[Message], Offset), Any] instead of Source[(Message, Offset), Any]. I wanted to ask if this is desirable change before I submit a PR.

@octonato
Hi @bossqone, sorry for the silence on the line.
I saw your PR and will comment there, but in a nutshell, the way it is now, it's backward-incompatible.

Hi guys
I have some spare time, and I would like to contribute patching lagom core. Since I don't have experience contributing with OSS projects. I would like to start with some first issues tag. If you allow me of course.
e.g. lagom/lagom#2553

@ihostage
@cajoruto No problem. Of course, you can help :+1:

Hmm, I think a user@root-lagom-foder/$ sbt +publishLocal before you try to load the project in IntelliJ should fix this issue. It sounds like a consequence of moving to sbt-dynver

Hi - I am deploying Lagom java services with persistance and message broker in Openshift platform and using discovery-method as kubernetes-api. I am having an issue in RBAC, as y orgnization does not give this Role and Role binding to be available for users. It is a financial organization and they say it is an Audit restriction to give all the pd objects which also contains environment variables along with it. Is there a way that we have a call to kubernettes to give only pod details rather than getting all pod objects. I see kubernettes mentions that api for get pod have "fields" passed in to be returned rather than getting all the details. Or is there a way that we contribute a different method to kubernettes which has to give back only pod detaiils and not the environment variables. doing kubernetes-api way of discovery makes life so easier, but this restriction makes to take other path, which is not so simple like this.

Hi @praajoo, unfortunately the cluster bootstrap operation sort of requires using kubernetes-api. Using akka-dns, for example, is not possible because the kubernetes DNS will not expose a POD until it’s ready and a lagom node is not ready until it has joind the cluster, and it won’t join the cluster until it can locate it’s peers that won’t be locatable until ready, and note ready until …
That being said, if you can think of alternative implementations for the discovery step of the cluster boostraping phase that don’t rely on Kubernetes api or extra RBAC settings it’d be a great addition!
I think this will be better contributed as an akka management subproject in https://github.com/akka/akka-management/

Thanks @ignasi35 , what I was thinking is instead of calling kubernetes api to return all the pod objects, if we can find another api of kubernetes which only gives the pod status and any other required pod details for the cluster start up, shall we use that for discovery phase !!! Let me try if that is feasible and like to contribute for it....

:point_up: June 23, 2020 6:48 AM :-) that’d be a great contribution! Please note that all discovery implementations and discussions are happening in https://github.com/akka/akka-management/

Hi, anyone tried Akka grpc in Lagom with maven ? I found some example with sbt. I am looking for a sample with maven to try it out in current project. Any help will be much appreciated

Hi, have you ever though about separating Play JSON serializer into a separate repository? It doesn't really depend on Lagom, and Akka's users could also benefit from it, but it being tied to Lagom's release cycle potentially stifles further development. I was thinking about generifying it a bit, so that a Circe serializer could be implemented, also providing an async alternative for migrations and serializers. If that is not something that Akka/Lagom team would want to take ownership of, I could do it myself, but I wonder how does the licensing impact any new open source development, since it can be considered to be a derived work. Could you comment on that?
