2019-04-24 08:39:16 UTC - Xue Shuai: Hi, every one, I try to test OW with `invoker_user_memory=256000m`, but when I invoke an action, I got error response, "Failed to provision resources to run the action." My server memory is 256Gb. Is there any upper limit for `invoker_user_memory`? Thank you.

2019-04-24 12:53:23 UTC - Christophe Jelger: Hi everyone. Is it possible to update the “kind” (and only this) of an action with `wsk`? I’m trying
```
wsk action update ACTION_NAME --kind nodejs:10
wsk action update ACTION_NAME --annotation exec nodejs:10
```
but it doesn’t work … any clue? Thx

----
2019-04-24 13:42:01 UTC - Christophe Jelger: the action has a runtime image no longer available on our platform (Adobe I/O Runtime) and I wanted to update all the actions that do have the old (removed) runtime

----
2019-04-24 13:43:36 UTC - Carlos Santana: I think I remember a corner case that you can't update if the current one is deprecated, worth opening an issue. I think @Rob Allen hit this at one point need it to reploy with action artifact.

----
2019-04-24 13:45:07 UTC - Carlos Santana: I think is a bug, since we are telling the user the current runtime on the action is not longer valid, and a new runtime is the valid one to move, lowest cost it would be to rename the `kind/exec`

2019-04-24 13:45:35 UTC - Christophe Jelger: ok I’ll open an issue: it’s indeed annoying to have to redeploy the code when one just wants to update the action kind

2019-04-24 13:46:17 UTC - Carlos Santana: I would love to see how you handle that in your automation scripts in CICD, you just deploy once and then just kind?

----
2019-04-24 13:48:11 UTC - Christophe Jelger: the problem is that we maintain multiple versions of our packages, like `foo@1.0.0`, `foo@1.1.0`, etc, and they always get deployed with `nodejs:latest`. The problem is that someone decided to remove the old kinds, and now we have a problem with old versions.

----
2019-04-24 13:59:36 UTC - Rodric Rabbah: it’s on the backend - updating the kind only when runtime is deprecated is perfectly reasonable

2019-04-24 14:05:35 UTC - Carlos Santana: It was an intentional easter egg, for who ever didn't read my PSA Tweets on nodejs6 is EOL April 30 update to nodejs10 before it becomes deprecated, because if not you can't just update the kind after that date :wink: :luckyegg:

2019-04-24 15:19:57 UTC - Oliver Stenbom: Hi there Whiskers!
I'm implementing "my own" invoker for my masters project at Imperial College that explores the use of checkpoint/restore to eliminate cold starts and increase serverless throughput.
Because of my lack of Scala knowledge, I'll be building a golang invoker that I'm hoping can nicely slot into any OpenWhisk deployment.
Could anyone verify that my understanding of the invoker communication is correct? It goes something like:
1. Get a unique id from zookeeper
2. Create a new kafka topic for "invokerx"
3. Send a ping message to the controller & start "ping" server (or does the controller send pings to the controller every x seconds)
4. Pull messages from activation queue, get function from entity store
5. ... Decide which container to run on etc. (the part which will be different for me)
6. Send active-ack to controller on "completedx" topic & store result in activationStore
Am i missing any communication here? Any extra info would be greatly appreciated before i end up getting it all wrong..
many thanks

----
2019-04-24 15:31:02 UTC - Rodric Rabbah: the model in general should be read image from a url like object store, and usually write it back to object store
if the action is a web action and you want to pass the image in the http request body, you’ll get the image as base64 encoded in `__ow_body`.
